MRD status predicts transplant benefit in NPM1-mutated AML
.
This survival benefit did not extend to patients who were MRD-negative after their second induction therapy, Jad Othman, MBBS, reported at the American Society of Hematology annual meeting.
The findings confirm the value of assessing MRD after induction chemotherapy to help identify patients with NPM1-mutated AML in first complete remission who are more likely to benefit from allogeneic transplant, said Dr. Othman, of King’s College London and Guy’s and St Thomas’ NHS Foundation Trust, London, and the University of Sydney, Australia.
Recently, updated European LeukemiaNet recommendations, which stratify patients with AML by favorable, intermediate, and adverse prognoses, now include a revised genetic-risk classification. This classification generally considers NPM1-mutated AML favorable risk. However, having a co-mutation with FLT3-ITD raises the risk to intermediate.
Despite this increased granularity in risk stratification, “it’s still not really clear who should have transplant in first remission with NPM1-mutated AML,” Dr. Othman said. “And there is still significant variation in practice, not just worldwide but even center to center.”
Although accumulating evidence suggests that MRD-negative patients with intermediate-risk AML are unlikely to benefit from allogeneic transplant in first complete remission, the presence of a FLT3-ITD mutation is often considered an indication for transplant, Othman explained. However, most studies supporting this view occurred before the development of sensitive molecular MRD measurement techniques.
The latest findings, from two sequential prospective randomized trials of intensive chemotherapy in adults aged 18-60 years with newly diagnosed AML may help clarify who will probably benefit from transplant and who won’t based on MRD status and relevant molecular features.
The first study (AML17), conducted from 2009 to 2014, selected patients for transplant in first complete remission using a validated risk score that incorporated features including age, sex, and response after therapy. The other (AML19), conducted from 2015 to 2020, selected patients with NPM1-mutated AML for transplant only if they tested positive for MRD in peripheral blood after their second course of treatment, regardless of FLT3-ITD status or other baseline risk factors.
Overall, the current analysis included the 737 patients with NPM1-mutated AML, 348 from AML17 and 389 from AML19, who were in complete remission after two courses of treatment and had an MRD sample at that point.
In AML17, 27% of MRD-positive patients (16 of 60) and 18% of MRD-negative patients (52 of 288) underwent transplant in first complete remission compared with 60% (50 of 83) and 16% (49 of 306), respectively, in AML19.
Among all 737 patients, Dr. Othman and colleagues did not observe an overall survival benefit among those who underwent transplant vs those who did not (hazard ratio [HR], 1.01) or among patients who were MRD-negative (HR, 0.82).
However, patients who were MRD-positive did have a significant survival advantage after transplant (HR, 0.39). In these patients, 3-year overall survival was 61% among those who underwent transplant vs 24% among those who did not.
In MRD-negative patients, transplant in first complete remission did not improve overall survival despite improved relapse-free survival (HR, 0.50). This outcome, Othman explained, probably occurred because most patients who did not undergo transplant and who relapsed were salvaged, with about two thirds undergoing a transplant during their second complete response.
Results in patients with NPM1 FLT3-ITD co-mutation mirrored those in the overall population: MRD-positive patients in first complete remission who underwent transplant demonstrated improved overall survival compared with those without transplant (HR, 0.52), but the overall survival benefit did not extend to MRD-negative patients (HR, 0.80).
The findings show that molecular MRD after induction chemotherapy can identify patients with NPM1-mutated AML who are more likely to benefit from transplant in first remission, Dr. Othman concluded. However, he noted, because only 16% of patients overall were older than 60 years, the results may not be generalizable to older patients.

Researchers making strides to better understand RA-associated interstitial lung disease
SAN DIEGO — Clinically significant interstitial lung disease (ILD) is believed to occur in 5%-10% of patients with rheumatoid arthritis (RA), but robust data are lacking on how to best predict which patients face the highest risk for RA-associated ILD. However, the results of several studies presented at the American College of Rheumatology annual meeting indicate that researchers are making strides in this field of rheumatologic care.
Adding Genetic Factors Improves ILD Risk Prediction
In the realm of risk stratification, Austin M. Wheeler, MD, a rheumatology fellow at the University of Nebraska Medical Center, Omaha, discussed the development and validation of a combined clinical and genetic risk score for ILD. “There is clear and well documented phenotypic and genetic overlap of ILD with idiopathic pulmonary fibrosis (IPF),” Dr. Wheeler said. “A number of clinical risk factors have been described for RA-ILD, including older age, male sex, smoking history, higher disease activity, and seropositivity. There are also well-documented genetic risk factors for RA-ILD. The MUC5B genetic variant is the strongest risk factor for IPF, and it’s been described in RA-ILD as well.”
A recently published study indicated that a genetic risk score without the MUC5B variant improved predictive ability for IPF and interstitial lung abnormalities better than using the MUC5B variant alone, “but no prior attempts have been made at developing a composite genetic risk score in RA-ILD” using both genetic and clinical risk factors, he said.
For the current study, Dr. Wheeler and colleagues drew from 2,386 participants in the Veterans Affairs Rheumatoid Arthritis (VARA) Registry, a multicenter, prospective cohort of US veterans with rheumatologist-diagnosed RA and who fulfilled the 1987 ACR classification criteria. The researchers validated ILD through a systematic review of medical records, including clinical diagnosis of ILD plus either imaging or lung biopsy findings, and collected whole genome data that included 12 single nucleotide polymorphisms (SNPs) previously identified to be associated with risk for RA-ILD. They then used a meta-analytic approach to create pooled associations for each of those respective SNPs using data from the VARA registry participants as well as participants from the past study where the SNPs were first identified. “Those pooled associations were what we used for our effects size within the genetic risk score,” which ended up using five of the SNPs, Dr. Wheeler explained. Next, he and his colleagues combined the genetic risk score with clinical risk factors including age, sex, smoking history, disease activity, and rheumatoid factor (RF) positivity to create their combined risk score.
The mean age of the cohort was 70 years, 89% were male, 78% had a smoking history, and 78% were anti–cyclic citrullinated peptide (CCP) antibody positive. Of the 2,386 participants, 224 (9.4%) had RA-ILD. The full composite risk score had the highest area under the receiver operating curve (AUC) of 0.67, compared with an AUC of 0.623 using the clinical factors alone, 0.651 using the clinical factors plus only the MUC5B variant, and 0.654 using the composite score minus only the MUC5B variant. These AUCs show that “the combined risk score performs better than clinical factors even without the inclusion of the MUC5B variant in the score, which is notable because it supports the importance of further investigation into polygenic risk scores in RA-ILD as there is clearly more at play in a patient’s overall genetic risk,” Dr. Wheeler said.
As an example of the composite score’s ability to discriminate between people with and without RA-ILD, a cutpoint of 0.05 gave a sensitivity of 90.2% and would have eliminated about 25% of the cohort from unnecessary high-resolution CT scans and pulmonary function tests, he said.
“This study demonstrates the potential utility of genetic risk scores in RA-ILD identification and supports further investigation into individual risk stratification and screening,” he concluded. “This isn’t ready for clinical applicability by any means, but I think it serves as a proof of concept of the idea of a genetic risk score in RA-ILD.”
Biomarker Score Investigated
In a separate abstract, Brent Luedders, MD, assistant professor of rheumatology and immunology at the University of Nebraska Medical Center, and colleagues set out to determine if a previously derived biomarker score is associated with prevalent and incident ILD in the same VARA Registry cohort. An abstract presented at the ACR 2022 annual meeting found that a panel derived from IPF peripheral biomarkers was significantly associated with RA-ILD, including matrix metalloproteinase (MMP)-2, -7, and -9, eotaxin, macrophage-derived chemokine (MDC), monocyte chemoattractant protein-1 (MCP-1), fms-like tyrosine kinase 3 ligand (Flt3L) and interleukin-8 (IL-8). For the current analysis, Dr. Luedders and colleagues measured the concentrations of seven biomarkers (MMP-7, MMP-9, eotaxin, MDC, MCP-1, Flt3L, IL-8) from serum/plasma samples collected from VARA’s participants at enrollment to develop a score based on the concentrations of each biomarker.
Baseline characteristics were similar between the groups, although those with prevalent RA-ILD were slightly older than those without ILD, and those who developed incident ILD during follow-up had slightly higher RA disease activity at the time of enrollment. When the researchers examined the association of the biomarker score with prevalent RA-ILD as a continuous measure, they found an adjusted OR of 1.08 for prevalent RA-ILD for each 1-point increase in the biomarker score. “When this was divided into quartiles, we found that the highest quartile of the biomarker score was associated with an adjusted odds ratio of 2.31 for prevalent RA-ILD,” Dr. Luedders said. “We saw a significant P for trend of < .001, suggesting a dose-response relationship, in which higher scores had higher risk.” Similar associations were observed for incident RA-ILD, in which participants with the highest quartile had an adjusted hazard ratio of 2.26 for incident RA-ILD.
The AUC of 0.653 that was obtained with clinical factors did not significantly improve with inclusion of the biomarker score, rising to only 0.669. “In receiver operating characteristic analysis, the addition of the biomarker score to clinical variables (age, sex, race, smoking status, anti-CCP positivity, and RA disease activity by DAS28) did not lead to a significant increase in the area under the curve. Therefore, further work is needed to identify combinations of clinical, biomarker, and other factors to accurately predict which people with RA will develop ILD,” he said.
Dr. Luedders acknowledged certain limitations of the results, including the fact that MMP-2 was not measured in this cohort and thus not included in the score. “This was an observational study with usual care; therefore, the absence of systemic evaluation for ILD may miss early or mild RA-ILD cases,” he added. “Similarly, a male predominance may limit the generalizability, and we have limited information on the RA-ILD pattern.” He concluded that the study results “support the shared pathogenesis of IPF and RA-ILD. However, we found that this score has limited discriminative performance, compared to clinical risk factors alone.”
Drilling Down on ILD Subtypes
In a poster abstract presentation at the meeting, Gregory Campbell McDermott, MD, MPH, a rheumatologist at Brigham and Women’s Hospital, Boston, highlighted results from a study that investigated differences in demographic, serologic, and lifestyle factors for RA-ILD and the major subtypes of RA-ILD: usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP). “Historically, RA-ILD has been studied as a single entity, even though we increasingly recognized that there are lots of different subtypes that fall under the umbrella of RA-ILD,” Dr. McDermott said in an interview. “We are also learning that the different subtypes probably have both prognostic and potentially therapeutic implications. For example, the UIP subtype, which is the most fibrotic subtype, has the worst prognosis but also may be a potential target for antifibrotic therapies. We’ve been trying to see if we can identify factors that are associated with specific subtypes, in particular the UIP subtype which has the worst prognosis.”
He and his colleagues examined 208 patients with RA-ILD with a mean age of 51 years and 547 patients with RA but no ILD with a mean age of 49 years from two RA cohorts comprising 3,328 patients: the Mass General Brigham Biobank RA Cohort and the Brigham RA Sequential Study (BRASS). Of the 208 RA-ILD cases, nearly half (48%) were RA-UIP, 18% were RA-NSIP, 8% were organizing pneumonia, 3% were respiratory bronchiolitis-ILD, and 23% were other/indeterminate. After conducting multivariable adjusted analyses, the researchers found that RA-ILD was associated with male sex (OR, 1.58; 95% CI, 1.09-2.23), seropositivity for RF and/or anti-CCP (OR, 2.22; 95% CI, 1.51-3.24) and being an ever smoker (OR, 1.70; 95% CI, 1.13-2.54). Having all three of these risk factors was strongly associated with RA-ILD (OR, 6.04; 95% CI, 2.92-12.47) and with RA-UIP in particular (OR, 7.1). “We found that a lot of the traditional RA-ILD risk factors like male sex, history of smoking, and seropositive status were most strongly associated with a UIP pattern,” Dr. McDermott said. “We think this is a first step in trying to understand how these different ILD subtypes may have different risk factors, pathogenesis, and potentially different treatments, prevention, and screening strategies.”
While clinicians wait for guidelines on systemic autoimmune rheumatic disease-associated ILD that are expected to be published by the ACR in 2024, he added that “we probably shouldn’t screen every single person with RA for ILD, but we need to identify people who have symptoms or findings on clinical exam. This study wasn’t designed to look specifically at who is at high risk, but I think we are moving toward that question: Who is high risk, and who’s asymptomatic [but] may need more screening?”
He pointed out limitations of the study, including its retrospective design and the fact that imaging was done for clinical purposes, “so it’s probably a higher risk group to begin with than the whole RA population,” he said. “We also didn’t have data on RA disease activity or erosions, some of these other measures that we think are important for understanding the full RA disease phenotype in these patients.”
Dr. Wheeler reported having no disclosures. Dr. Luedders reported that his study was supported by the VA, the Rheumatology Research Foundation, and the University of Nebraska Medical Center Mentored Scholars Program. Dr. McDermott reported that his study was supported by the Rheumatology Research Foundation.

Wheeler, MD, a rheumatology fellow at the University of Nebraska Medical Center, Omaha, discussed the development and validation of a combined clinical and genetic risk score for ILD. “There is clear and well documented phenotypic and genetic overlap of ILD with idiopathic pulmonary fibrosis (IPF),” Dr. Wheeler said. “A number of clinical risk factors have been described for RA-ILD, including older age, male sex, smoking history, higher disease activity, and seropositivity. There are also well-documented genetic risk factors for RA-ILD. The MUC5B genetic variant is the strongest risk factor for IPF, and it’s been described in RA-ILD as well.”
A recently published study indicated that a genetic risk score without the MUC5B variant improved predictive ability for IPF and interstitial lung abnormalities better than using the MUC5B variant alone, “but no prior attempts have been made at developing a composite genetic risk score in RA-ILD” using both genetic and clinical risk factors, he said.
For the current study, Dr. Wheeler and colleagues drew from 2,386 participants in the Veterans Affairs Rheumatoid Arthritis (VARA) Registry, a multicenter, prospective cohort of US veterans with rheumatologist-diagnosed RA and who fulfilled the 1987 ACR classification criteria. The researchers validated ILD through a systematic review of medical records, including clinical diagnosis of ILD plus either imaging or lung biopsy findings, and collected whole genome data that included 12 single nucleotide polymorphisms (SNPs) previously identified to be associated with risk for RA-ILD. They then used a meta-analytic approach to create pooled associations for each of those respective SNPs using data from the VARA registry participants as well as participants from the past study where the SNPs were first identified. “Those pooled associations were what we used for our effects size within the genetic risk score,” which ended up using five of the SNPs, Dr. Wheeler explained. Next, he and his colleagues combined the genetic risk score with clinical risk factors including age, sex, smoking history, disease activity, and rheumatoid factor (RF) positivity to create their combined risk score.
The mean age of the cohort was 70 years, 89% were male, 78% had a smoking history, and 78% were anti–cyclic citrullinated peptide (CCP) antibody positive. Of the 2,386 participants, 224 (9.4%) had RA-ILD. The full composite risk score had the highest area under the receiver operating curve (AUC) of 0.67, compared with an AUC of 0.623 using the clinical factors alone, 0.651 using the clinical factors plus only the MUC5B variant, and 0.654 using the composite score minus only the MUC5B variant. These AUCs show that “the combined risk score performs better than clinical factors even without the inclusion of the MUC5B variant in the score, which is notable because it supports the importance of further investigation into polygenic risk scores in RA-ILD as there is clearly more at play in a patient’s overall genetic risk,” Dr. Wheeler said.
As an example of the composite score’s ability to discriminate between people with and without RA-ILD, a cutpoint of 0.05 gave a sensitivity of 90.2% and would have eliminated about 25% of the cohort from unnecessary high-resolution CT scans and pulmonary function tests, he said.
“This study demonstrates the potential utility of genetic risk scores in RA-ILD identification and supports further investigation into individual risk stratification and screening,” he concluded. “This isn’t ready for clinical applicability by any means, but I think it serves as a proof of concept of the idea of a genetic risk score in RA-ILD.”
Biomarker Score Investigated
In a separate abstract, Brent Luedders, MD, assistant professor of rheumatology and immunology at the University of Nebraska Medical Center, and colleagues set out to determine if a previously derived biomarker score is associated with prevalent and incident ILD in the same VARA Registry cohort. An abstract presented at the ACR 2022 annual meeting found that a panel derived from IPF peripheral biomarkers was significantly associated with RA-ILD, including matrix metalloproteinase (MMP)-2, -7, and -9, eotaxin, macrophage-derived chemokine (MDC), monocyte chemoattractant protein-1 (MCP-1), fms-like tyrosine kinase 3 ligand (Flt3L) and interleukin-8 (IL-8). For the current analysis, Dr. Luedders and colleagues measured the concentrations of seven biomarkers (MMP-7, MMP-9, eotaxin, MDC, MCP-1, Flt3L, IL-8) from serum/plasma samples collected from VARA’s participants at enrollment to develop a score based on the concentrations of each biomarker.
Baseline characteristics were similar between the groups, although those with prevalent RA-ILD were slightly older than those without ILD, and those who developed incident ILD during follow-up had slightly higher RA disease activity at the time of enrollment. When the researchers examined the association of the biomarker score with prevalent RA-ILD as a continuous measure, they found an adjusted OR of 1.08 for prevalent RA-ILD for each 1-point increase in the biomarker score. “When this was divided into quartiles, we found that the highest quartile of the biomarker score was associated with an adjusted odds ratio of 2.31 for prevalent RA-ILD,” Dr. Luedders said. “We saw a significant P for trend of < .001, suggesting a dose-response relationship, in which higher scores had higher risk.” Similar associations were observed for incident RA-ILD, in which participants with the highest quartile had an adjusted hazard ratio of 2.26 for incident RA-ILD.
The AUC of 0.653 that was obtained with clinical factors did not significantly improve with inclusion of the biomarker score, rising to only 0.669. “In receiver operating characteristic analysis, the addition of the biomarker score to clinical variables (age, sex, race, smoking status, anti-CCP positivity, and RA disease activity by DAS28) did not lead to a significant increase in the area under the curve. Therefore, further work is needed to identify combinations of clinical, biomarker, and other factors to accurately predict which people with RA will develop ILD,” he said.
Dr. Luedders acknowledged certain limitations of the results, including the fact that MMP-2 was not measured in this cohort and thus not included in the score. “This was an observational study with usual care; therefore, the absence of systemic evaluation for ILD may miss early or mild RA-ILD cases,” he added. “Similarly, a male predominance may limit the generalizability, and we have limited information on the RA-ILD pattern.” He concluded that the study results “support the shared pathogenesis of IPF and RA-ILD. However, we found that this score has limited discriminative performance, compared to clinical risk factors alone.”
Drilling Down on ILD Subtypes
In a poster abstract presentation at the meeting, Gregory Campbell McDermott, MD, MPH, a rheumatologist at Brigham and Women’s Hospital, Boston, highlighted results from a study that investigated differences in demographic, serologic, and lifestyle factors for RA-ILD and the major subtypes of RA-ILD: usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP). “Historically, RA-ILD has been studied as a single entity, even though we increasingly recognized that there are lots of different subtypes that fall under the umbrella of RA-ILD,” Dr. McDermott said in an interview. “We are also learning that the different subtypes probably have both prognostic and potentially therapeutic implications. For example, the UIP subtype, which is the most fibrotic subtype, has the worst prognosis but also may be a potential target for antifibrotic therapies. We’ve been trying to see if we can identify factors that are associated with specific subtypes, in particular the UIP subtype which has the worst prognosis.”
He and his colleagues examined 208 patients with RA-ILD with a mean age of 51 years and 547 patients with RA but no ILD with a mean age of 49 years from two RA cohorts comprising 3,328 patients: the Mass General Brigham Biobank RA Cohort and the Brigham RA Sequential Study (BRASS). Of the 208 RA-ILD cases, nearly half (48%) were RA-UIP, 18% were RA-NSIP, 8% were organizing pneumonia, 3% were respiratory bronchiolitis-ILD, and 23% were other/indeterminate. After conducting multivariable adjusted analyses, the researchers found that RA-ILD was associated with male sex (OR, 1.58; 95% CI, 1.09-2.23), seropositivity for RF and/or anti-CCP (OR, 2.22; 95% CI, 1.51-3.24) and being an ever smoker (OR, 1.70; 95% CI, 1.13-2.54). Having all three of these risk factors was strongly associated with RA-ILD (OR, 6.04; 95% CI, 2.92-12.47) and with RA-UIP in particular (OR, 7.1). “We found that a lot of the traditional RA-ILD risk factors like male sex, history of smoking, and seropositive status were most strongly associated with a UIP pattern,” Dr. McDermott said. “We think this is a first step in trying to understand how these different ILD subtypes may have different risk factors, pathogenesis, and potentially different treatments, prevention, and screening strategies.”
While clinicians wait for guidelines on systemic autoimmune rheumatic disease-associated ILD that are expected to be published by the ACR in 2024, he added that “we probably shouldn’t screen every single person with RA for ILD, but we need to identify people who have symptoms or findings on clinical exam. This study wasn’t designed to look specifically at who is at high risk, but I think we are moving toward that question: Who is high risk, and who’s asymptomatic [but] may need more screening?”
He pointed out limitations of the study, including its retrospective design and the fact that imaging was done for clinical purposes, “so it’s probably a higher risk group to begin with than the whole RA population,” he said. “We also didn’t have data on RA disease activity or erosions, some of these other measures that we think are important for understanding the full RA disease phenotype in these patients.”

Sickle Cell: Good Outcomes for Haploidentical Transplants
Of 42 patients aged 15-45 who were fully treated, 95% survived to 2 years post transplant (overall survival, (95% CI, 81.5%-98.7%), and 88% reached the primary endpoint of event-free survival at 2 years (95% CI, 73.5%-94.8%), according to the findings, which were released at the annual meeting of the American Society of Hematology.
At an ASH news briefing, study lead author Adetola A. Kassim, MBBS, MS, of Vanderbilt University Medical Center, in Nashville, Tennessee, said the results support haploidentical stem cell transplants “as a suitable and tolerable curative therapy for adults with sickle cell disease and severe end-organ toxicity such as stroke or pulmonary hypertension, a population typically excluded from participating in gene therapy.”
Dr. Kassim added that the findings are especially promising since there are so many potential donors in stem-cell transplants: “Your siblings can be donors, your parents can be donors, your cousins can be donors. First-, second-, and third-degree relatives can be donors. So there’s really endless donors within the family.”
In an interview, Mayo Clinic SCD specialist Asmaa Ferdjallah, MD, MPH, of Mayo Clinic in Rochester, Minnesota, who was not involved with the study but is familiar with its findings, said stem cell transplant is the only option to cure SCD.
“This is advantageous because SCD is otherwise a chronic disease that is marked by chronic pain, risk of stroke, frequent interruptions of school/work due to sick days, and decreased life span,” she said. “Most patients, assuming they can tolerate the conditioning chemotherapy that is given before transplant, are eligible.”
Matched sibling donors are preferable, but they can be hard to find, she said. It hasn’t been clear whether half-matched donors are feasible options in SCD, she said. “This means that, if you are a patient with sickle cell disease, and you don’t have a suitable matched donor, haploidentical transplant is not a recommendation we can make outside of enrollment in a clinical trial.”
For the study, researchers enlisted 54 patients with SCD and prior stroke, recurrent acute chest syndrome or pain, chronic transfusion regimen, or tricuspid valve regurgitant jet velocity ≥2.7 m/sec. Participants had to have an HLA-haploidentical first-degree relative donor who would donate bone marrow.
“The median age was 22.8 years at enrollment; 47/54 (87%) of enrolled participants had hemoglobin SS disease, 40/54 (74.1%) had a Lansky/Karnofsky score of 90-100 at baseline, and 41/54 (75.9%) had an HLA match score of 4/8,” the researchers reported. “Recurrent vaso-occlusive pain episodes (38.9%), acute chest syndrome (16.8%), and overt stroke (16.7%) were the most common indications for transplant.”
“We knew going into this that we were going to get very high-risk patients,” Dr. Kassim said.
Forty-two patients went through with transplants. As for adverse events, 2 patients died, all within the first year, of organ failure and acute respiratory distress syndrome; 4.8% of participants had primary graft failure, and 2.4% had secondary graft failure before day 100. “The cumulative incidence of grades II-IV acute GVHD [graft-versus-host disease] at day 100 was 26.2% (95% CI, 14.0%-40.2%), and grades III-IV acute GVHD at day 100 was 4.8% (95% CI, 0.9%-14.4%).”
The outcomes are similar to those in transplants with matched sibling donors, Dr. Kassim said.
Dr. Ferdjallah said the new study is “robust” and impressive, although it’s small.
“As a clinician, these are the kind of outcomes I have been hoping for,” Dr. Ferdjallah said. “I have been very reluctant to suggest haploidentical transplant for my sickle cell disease patients. However, reviewing the results of this study with my motivated patients and families can help us both to use shared medical decision-making and come together with what is best for that specific patient.”
As for adverse events, she said they “confirm a fear of using haploidentical transplant, which is graft failure. Fortunately, out of 42 who proceeded to transplant, only 2 had primary graft failure and 1 had secondary graft failure. This is not overtly a large number. Of course, we would hope for more durable engraftment. The other side effects including GVHD and infection are all to be expected.”
As for cost, Dr. Kassim said the transplants run from $200,000 to $400,000 vs over $2 million for gene therapy, and Dr. Ferdjallah said insurance is likely to cover the treatment.
Moving ahead, Dr. Ferdjallah said she looks forward to getting study data about pediatric patients specifically. For now, “we should consider HLA-haploidentical seriously in patients with sickle cell disease and no available HLA-matched donors.”
Grants to the Blood and Marrow Transplant Clinical Trials Network from the National Heart, Lung, and Blood Institute and National Cancer Institute funded the study. Dr. Kassim had no disclosures.

Measurable residual disease–guided therapy promising for CLL
The targeted therapy combination was also associated with better progression-free survival among patients with CLL with worse prognostic features, including immunoglobulin heavy chain variable (IGHV) unmutated disease and cytogenetic abnormalities, such as the 11q deletion, trisomy 12, and 13q deletion.
Personalizing treatment duration of ibrutinib-venetoclax, as determined by measurable residual disease (MRD), allowed more than half of patients assigned to the combination therapy to stop therapy by 3 years because they had achieved MRD negativity, reported Peter Hillmen, MBChB, PhD, from the Leeds Institute of Medical Research at St James’s University Hospital in Leeds, United Kingdom.
The shorter course of therapy could help to ameliorate toxicities and lower the risk for the development of drug-resistant disease, he said.
“This is the first trial to show that an MRD-guided approach with treatment beyond [MRD] negativity has a significant advantage over chemoimmunotherapy, both in terms of [progression-free] and overall survival. Over 90% of patients achieve an MRD-negative in this combination in the peripheral blood,” said Dr. Hillmen in a media briefing prior to his presentation of the data in an oral abstract session here at the American Society of Hematology annual meeting.
The study results were also published online in The New England Journal of Medicine to coincide with the presentation.
Adaptive Trial
The FLAIR study is a phase 3 open-label platform trial that initially compared ibrutinib-rituximab with fludarabine-cyclophosphamide-rituximab (FCR) in patients with untreated CLL. However, in 2017 the trial was adapted to include both an ibrutinib monotherapy and an ibrutinib-venetoclax arm with therapy duration determined by MRD.
At ASH 2023, Dr. Hillmen presented data from an interim analysis of 523 patients comparing ibrutinib-venetoclax with FCR.
In the ibrutinib-venetoclax group, patients received oral ibrutinib 420 mg daily, with venetoclax added after 2 months, beginning with a 20-mg dose ramped up to 400 mg in a weekly dose-escalation schedule. The combination could be given for 2-6 years, depending on MRD responses. FCR was delivered in up to six cycles of 28 days each. Two thirds of patients assigned to FCR completed all six cycles.
After a median follow-up of 43.7 months, 12 patients (4.6%) randomly assigned to ibrutinib-venetoclax had disease progression or died compared with 75 patients (28.5%) assigned to FCR. The estimated 3-year progression-free survival with ibrutinib-venetoclax was 97.2%, compared with 76.8% with FCR, translating into a hazard ratio (HR) for progression or death with the targeted therapy combination of 0.13 (P <.001).
Among patients with unmutated IGHV, the combination led to improved progression-free survival compared with FCR (hazard ratio [HR] for progression or death, 0.07); for patients with mutated IGHV, however, the combination did not improve progression-free survival (HR, 0.54; 95% CI, 0.21-1.38).
In all, eight patients (3.5%) assigned to ibrutinib-venetoclax and 23 assigned to FCR (9.5%) died.
The 3-year overall survival rates were 98% in the targeted therapy group vs 93% in the FCR group (HR for progression or death, 0.31).
At 2 years, 52.4% of patients assigned to ibrutinib-venetoclax had undetectable MRD in bone marrow compared with 49.8% with FCR. At 5 years, the respective percentages for MRD in bone marrow were 65.9% vs 49.8% and 92.7% vs 67.9% for MRD in peripheral blood.
The safety analysis showed higher rates of blood and lymphatic system disorders with FCR, whereas cardiac, metabolic/nutrition disorders, and eye disorders occurred more frequent with ibrutinib-venetoclax.
A total of 24 secondary cancers were diagnosed in 17 patients randomly assigned to ibrutinib-venetoclax and 45 secondary cancers among 34 patients randomly assigned to FCR. One patient assigned to ibrutinib-venetoclax developed myelodysplastic syndrome/acute myeloid leukemia (AML), as did eight patients assigned to FCR. One patient in the ibrutinib-venetoclax arm and four patients in the FCR arm had Richter’s transformation.
The incidence rate for other cancers was 2.6 per 100 person-years with ibrutinib-venetoclax compared with 5.4 per 100 person-years with FCR.
The most frequently occurring cancers in each arm were basal cell or squamous cell carcinomas. The incidence of myelodysplastic syndromes, AML lymphoma, and prostate/urologic cancers was higher among patients on FCR.
This research “unequivocally shows the superiority of targeted therapy over traditional cytotoxic chemotherapy,” commented briefing moderator Mikkael A. Sekeres, MD, from the University of Miami Miller School of Medicine.
The ibrutinib-venetoclax combination has the potential to reduce the incidence of myelodysplastic syndromes secondary to CLL therapy, Dr. Sekeres suggested.
“As someone who specializes in leukemia and myelodysplastic syndromes, I have the feeling I won’t be seeing these CLL patients in my clinic — years after being treated for CLL — much longer,” he said.
In an interview with this news organization, Lee Greenberger, PhD, said that “I think that duration-adapted therapy is a great story. Using MRD negativity is a perfectly justified way, I think, to go about a new combination that’s going to be really potent for CLL patients and probably give them many years of treatment and then to get off the drug, because ultimately the goal is to get cures.”
This combination, though highly efficacious, is unlikely to be curative; however, because even when MRD is undetectable, “it will come back,” said Dr. Greenberger, chief scientific officer for the Leukemia & Lymphoma Society.
Dr. Greenberger added that MRD testing of bone marrow, which provides a more detailed picture of MRD status than testing of peripheral blood, is feasible in academic medical centers but may be a barrier to MRD-adapted therapy in community oncology practices.

The targeted therapy combination was also associated with better progression-free survival among patients with CLL with worse prognostic features, including immunoglobulin heavy chain variable (IGHV) unmutated disease and cytogenetic abnormalities, such as the 11q deletion, trisomy 12, and 13q deletion.

However, in 2017 the trial was adapted to include both an ibrutinib monotherapy and an ibrutinib-venetoclax arm with therapy duration determined by MRD.
At ASH 2023, Dr. Hillmen presented data from an interim analysis of 523 patients comparing ibrutinib-venetoclax with FCR.
In the ibrutinib-venetoclax group, patients received oral ibrutinib 420 mg daily, with venetoclax added after 2 months, beginning with a 20-mg dose ramped up to 400 mg in a weekly dose-escalation schedule. The combination could be given for 2-6 years, depending on MRD responses. FCR was delivered in up to six cycles of 28 days each. Two thirds of patients assigned to FCR completed all six cycles.
After a median follow-up of 43.7 months, 12 patients (4.6%) randomly assigned to ibrutinib-venetoclax had disease progression or died compared with 75 patients (28.5%) assigned to FCR. The estimated 3-year progression-free survival with ibrutinib-venetoclax was 97.2%, compared with 76.8% with FCR, translating into a hazard ratio (HR) for progression or death with the targeted therapy combination of 0.13 (P <.001).
Among patients with unmutated IGHV, the combination led to improved progression-free survival compared with FCR (hazard ratio [HR] for progression or death, 0.07); for patients with mutated IGHV, however, the combination did not improve progression-free survival (HR, 0.54; 95% CI, 0.21-1.38).
In all, eight patients (3.5%) assigned to ibrutinib-venetoclax and 23 assigned to FCR (9.5%) died.
The 3-year overall survival rates were 98% in the targeted therapy group vs 93% in the FCR group (HR for progression or death, 0.31).
At 2 years, 52.4% of patients assigned to ibrutinib-venetoclax had undetectable MRD in bone marrow compared with 49.8% with FCR. At 5 years, the respective percentages for MRD in bone marrow were 65.9% vs 49.8% and 92.7% vs 67.9% for MRD in peripheral blood.
The safety analysis showed higher rates of blood and lymphatic system disorders with FCR, whereas cardiac, metabolic/nutrition disorders, and eye disorders occurred more frequent with ibrutinib-venetoclax.
A total of 24 secondary cancers were diagnosed in 17 patients randomly assigned to ibrutinib-venetoclax and 45 secondary cancers among 34 patients randomly assigned to FCR. One patient assigned to ibrutinib-venetoclax developed myelodysplastic syndrome/acute myeloid leukemia (AML), as did eight patients assigned to FCR. One patient in the ibrutinib-venetoclax arm and four patients in the FCR arm had Richter’s transformation.
The incidence rate for other cancers was 2.6 per 100 person-years with ibrutinib-venetoclax compared with 5.4 per 100 person-years with FCR.
The most frequently occurring cancers in each arm were basal cell or squamous cell carcinomas. The incidence of myelodysplastic syndromes, AML lymphoma, and prostate/urologic cancers was higher among patients on FCR.
This research “unequivocally shows the superiority of targeted therapy over traditional cytotoxic chemotherapy,” commented briefing moderator Mikkael A. Sekeres, MD, from the University of Miami Miller School of Medicine.
The ibrutinib-venetoclax combination has the potential to reduce the incidence of myelodysplastic syndromes secondary to CLL therapy, Dr. Sekeres suggested.
“As someone who specializes in leukemia and myelodysplastic syndromes, I have the feeling I won’t be seeing these CLL patients in my clinic — years after being treated for CLL — much longer,” he said.
In an interview with this news organization, Lee Greenberger, PhD, said that “I think that duration-adapted therapy is a great story. Using MRD negativity is a perfectly justified way, I think, to go about a new combination that’s going to be really potent for CLL patients and probably give them many years of treatment and then to get off the drug, because ultimately the goal is to get cures.”
This combination, though highly efficacious, is unlikely to be curative; however, because even when MRD is undetectable, “it will come back,” said Dr. Greenberger, chief scientific officer for the Leukemia & Lymphoma Society.
Dr. Greenberger added that MRD testing of bone marrow, which provides a more detailed picture of MRD status than testing of peripheral blood, is feasible in academic medical centers but may be a barrier to MRD-adapted therapy in community oncology practices.
The FLAIR study is supported by grants from Cancer Research UK, Janssen, Pharmacyclics, and AbbVie. Dr. Hillmen disclosed employment and equity participation with Apellis Pharmaceuticals. Dr. Sekeres disclosed board activities for Geron, Novartis, and Bristol-Myers Squibb and owner of stock options Kurome. Dr. Greenberger reported no relevant financial disclosures.

The targeted therapy combination was also associated with better progression-free survival among patients with CLL with worse prognostic features, including immunoglobulin heavy chain variable (IGHV) unmutated disease and cytogenetic abnormalities, such as the 11q deletion, trisomy 12, and 13q deletion.
Personalizing treatment duration of ibrutinib-venetoclax, as determined by measurable residual disease (MRD), allowed more than half of patients assigned to the combination therapy to stop therapy by 3 years because they had achieved MRD negativity, reported Peter Hillmen, MBChB, PhD, from the Leeds Institute of Medical Research at St James’s University Hospital in Leeds, United Kingdom.
The shorter course of therapy could help to ameliorate toxicities and lower the risk for the development of drug-resistant disease, he said.
“This is the first trial to show that an MRD-guided approach with treatment beyond [MRD] negativity has a significant advantage over chemoimmunotherapy, both in terms of [progression-free] and overall survival. Over 90% of patients achieve an MRD-negative in this combination in the peripheral blood,” said Dr. Hillmen in a media briefing prior to his presentation of the data in an oral abstract session here at the American Society of Hematology annual meeting.
The study results were also published online in The New England Journal of Medicine to coincide with the presentation.

Mantle Cell Lymphoma: Drug Combo Improves PFS
Still, “in the countries where ibrutinib is indicated, this combination should be a new standard therapy for relapsed/refractory mantle cell lymphoma,” Michael Wang, MD, of the University of Texas MD Anderson Cancer Center, Houston, said in a media briefing at the annual meeting of the American Society of Hematology.
Its use would be off label, according to the authors of the industry-funded trial, because no nation has approved the combination therapy for MCL, a rare, aggressive form of non-Hodgkin lymphoma.
As Dr. Wang noted, ibrutinib (a Bruton tyrosine kinase inhibitor) is approved by the Food and Drug Administration to treat MCL, while venetoclax (a BCL-2 inhibitor) is approved for chronic lymphocytic leukemia and previously untreated acute myeloid leukemia. “The combination of these two agents leverages complementary modes of action and has demonstrated synergistic anti-tumor activity in preclinical models of mantle cell lymphoma,” he said. And “in patients with relapsed/refractory mantle cell lymphoma, promising clinical activity has also been observed in early-phase studies.”
For the multinational, randomized, phase 3, double-blind SYMPATICO study, researchers assigned 267 adults with relapsed/refractory MCL after 1-5 prior therapies 1:1 to receive oral ibrutinib 560 mg daily with oral venetoclax (standard 5-wk ramp-up to a target dose of 400 mg once daily) or placebo for 2 years. Then they continued with ibrutinib alone until progressive disease or unacceptable toxicity.
The study began in 2017. The median age of patients was 68, and the numbers of patients in each group were 134 (both drugs) and 133 (ibrutinib plus placebo).
At a median of 51.2 months, median PFS — the primary endpoint — was higher in the combination group vs. ibrutinib alone (31.9 vs. 22.1 months, hazard ratio [HR]=0.65, 95% CI, 0.47–0.88, P = .0052). While overall survival was higher in the combination group vs. ibrutinib alone, an interim analysis found that the difference was not statistically significant (44.9 months vs. 38.6 months, 95% CI, HR = 0.85, 0.62-1.19, P = .3465).
When questioned about this finding at the ASH news briefing, Dr. Wang said that 170 events are needed for a full overall survival analysis, and there are just 144 now. The study may reach that point in early 2025, he said.
Over a median treatment duration of 22.0 months for the combination treatment and 17.7 months for ibrutinib alone, grade ≥ 3 adverse events occurred in 84% and 76% of patients, respectively. At 60%, the level of serious adverse events was the same in both groups.
In an interview, Brian T. Hill, MD, PhD, of Cleveland Clinic, noted that in general, MCL “has a pretty relentless pattern of relapses and disease progression without an easy cure in the vast majority of patients.”
Ibrutinib has revolutionized treatment over the past decade with generally manageable side effects, and clinicians are now turning to other Bruton tyrosine kinase inhibitors, he said. Still, “there is a need for improving the durability and the response rates second-line treatment or beyond,” Dr. Hill said.
The new study is important since it’s the first randomized trial “that demonstrates that additional venetoclax significantly improves not only response rates, but also progression-free survival with a trend toward overall survival,” he said. “The toxicity profile doesn’t really seem to be significantly more worse than what we might expect with each agent given individually.”
However, Dr. Hill noted that “it’s a relatively small study and relatively short follow-up.”
It may be difficult to get an ibrutinib-venetoclax combination approved today since ibrutinib is no longer the preferred Bruton tyrosine kinase inhibitor for clinicians, he said.
Pharmacyclics, maker of ibrutinib, is the study sponsor and Janssen is a collaborator.
Dr. Wang reports research funding Acerta Pharma, AstraZeneca, BeiGene, BioInvent, Celgene, Genentech, Innocare, Janssen, Juno Therapeutics, Kite Pharma, Lilly, Loxo Oncology, Molecular Templates, Oncternal, Pharmacyclics, and VelosBio. Other authors report multiple and various relationships with industry. Dr. Hill discloses research funding and consulting relationships with Pharmacyclics, AbbVie, BeiGene, and AstraZeneca.

‘Baby TAM’ effective, tolerable for breast cancer prevention
SAN ANTONIO — The drug can reduce incidence of breast cancer in high-risk individuals, but side effects that mimic menopause have led to low rates of uptake. Lower-dose tamoxifen aims to reduce those side effects, but there remains some uncertainty about the minimum dose required to maintain efficacy.
The TAM-01 study, first published in 2019, demonstrated that a 5-mg dose of tamoxifen led to a reduction in recurrence of invasive breast cancer or ductal carcinoma in situ (DCIS). At the San Antonio Breast Cancer Symposium, two studies were presented that provided insight into dose efficacy and likelihood of medication adherence in women taking baby TAM.
“We all know that women who are at increased risk for breast cancer may benefit from the use of tamoxifen to help lower their risk, although historical uptake to tamoxifen in the prevention setting has been quite low,” said Lauren Cornell, MD, during a presentation. Her team investigated the impact of patient counseling on how well they understood their risk, as well as their likelihood of adherence to the medication.
The study included 41 women, and 31 completed follow-up at 1 year. “We saw that 90% of our patients reported good or complete understanding of their breast cancer risk after the consultation, emphasizing the benefit of that consult, and 73% reported that the availability of baby tamoxifen helped in their decision to consider a preventative medication,” said Dr. Cornell during her presentation. After 1 year of follow-up, 74% said that they had initiated baby tamoxifen, and 78% of those who started taking the drug were still taking it at 1 year.
Participants who continued to take baby TAM at 1 year had a higher estimated breast cancer risk (IBIS 10-year risk, 12.7% vs 7.6%; P = .027) than those who discontinued. “We saw that uptake to baby TAM after informed discussion in patients who qualify is high, especially in those patients with high risk and intraepithelial lesions or DCIS, and adherence and tolerability at 1 year follow up is improved, compared to what we would expect with traditional dosing of tamoxifen. It’s important to note that the NCCN guidelines and the ASCO clinical practice update now include low-dose tamoxifen as an option for select women, and future randomized control trials on de-escalation of tamoxifen and high-risk patients based on their risk model assessment still need to be done. Future study should also focus on markers to identify candidates best suited for low versus standard dose of tamoxifen,” said Dr. Cornell, who is an assistant professor of medicine at Mayo Clinic Florida in Jacksonville.
At another SABCS session, Per Hall, MD, PhD, discussed findings from the previously published KARISMA-2 study, which examined efficacy of various doses of tamoxifen. A total of 1440 participants, 240 in each arm, received tamoxifen doses of 20 mg, 10 mg, 5 mg, 2.5 mg, 1 mg, or placebo. During his talk, Dr. Hall pointed out that measuring outcomes would take a very large number of participants to identify small differences in breast cancer rates. Therefore, the researchers examined breast density changes as a proxy. As a noninferiority outcome, the researchers used the proportion of women in each arm who achieved the median decrease in breast density seen at 20 mg of tamoxifen, which is 10.1%.
The women underwent mammograms at baseline and again at 6 months to determine change in breast density. Among all women in the study, the proportion of patients who had a similar breast density reduction as the 20-mg dose were very similar in the 10 mg (50.0%; P = .002), 5 mg (49.3%; P < .001), and 2.5 mg (52.5%; P < .001) groups. The 1 mg group had a proportion of 39.5% (P = .138), while the placebo group had 38.9% (P = .161). However, the results were driven by premenopausal women, where the values were 63.3%, 70.7%, 74.4%, and 69.7% in the 20-mg, 10-mg, 5-mg, and 2.5-mg groups, respectively, and 32.9% at 1 mg and 29.7% on placebo. In postmenopausal women, the values were 41.9%, 36.7%, 33.3%, and 41.9% in the 20-mg, 10-mg, 5-mg, and 2.5-mg groups, with values of 44.2% in the 1-mg group and 43.8% in the placebo group.
The median density change was 18.5% in premenopausal women and 4.0% in postmenopausal women.
“We didn’t see anything in the postmenopausal women. The decrease for those on 20 milligrams and those on placebo were exactly the same. Why this is, we still don’t know because we do know that tamoxifen in the adjuvant setting could be used for postmenopausal women. It could be that 6 months is too short of a time [to see a benefit]. We don’t know,” said Dr. Hall, who is a medical epidemiologist and biostatistician at Karolinska Institutet, Stockholm, Sweden.
Severe vasomotor side effects like hot flashes, cold flashes, and night sweats were reduced by about 50% in the lower tamoxifen doses, compared with 20 mg.
Dr. Hall also pointed out that tamoxifen is a prodrug. The CYP2D6 enzyme produces a range of metabolites, with endoxifen having the strongest affinity to the estrogen receptor and being present at the highest plasma concentration. He showed a table of endoxifen plasma levels at various tamoxifen doses in women of various metabolizer status, ranging from poor to ultrafast. Among intermediate, normal, and ultrarapid metabolizers, 5- and 10-mg doses produced plasma endoxifen levels ranging from 2.4 to 6.2 ng/mL, which represents a good therapeutic window. “For intermediate and normal metabolizers, it could be that 5 mg [of tamoxifen] is enough, but I want to underline that we didn’t use breast cancer incidence or recurrence in this study, we used density change, so we should be careful when we use these results,” said Dr. Hall. His group is now conducting the KARISMA Endoxifen trial, which will test endoxifen directly at doses of 1 and 2 mg.
Dr. Cornell has no relevant financial disclosures. Dr. Hall is a member of the scientific advisory board for Atossa Therapeutics.

It’s important to note that the NCCN guidelines and the ASCO clinical practice update now include low-dose tamoxifen as an option for select women, and future randomized control trials on de-escalation of tamoxifen and high-risk patients based on their risk model assessment still need to be done. Future study should also focus on markers to identify candidates best suited for low versus standard dose of tamoxifen,” said Dr. Cornell, who is an assistant professor of medicine at Mayo Clinic Florida in Jacksonville.
At another SABCS session, Per Hall, MD, PhD, discussed findings from the previously published KARISMA-2 study, which examined efficacy of various doses of tamoxifen. A total of 1440 participants, 240 in each arm, received tamoxifen doses of 20 mg, 10 mg, 5 mg, 2.5 mg, 1 mg, or placebo. During his talk, Dr. Hall pointed out that measuring outcomes would take a very large number of participants to identify small differences in breast cancer rates. Therefore, the researchers examined breast density changes as a proxy. As a noninferiority outcome, the researchers used the proportion of women in each arm who achieved the median decrease in breast density seen at 20 mg of tamoxifen, which is 10.1%.
The women underwent mammograms at baseline and again at 6 months to determine change in breast density. Among all women in the study, the proportion of patients who had a similar breast density reduction as the 20-mg dose were very similar in the 10 mg (50.0%; P = .002), 5 mg (49.3%; P < .001), and 2.5 mg (52.5%; P < .001) groups. The 1 mg group had a proportion of 39.5% (P = .138), while the placebo group had 38.9% (P = .161). However, the results were driven by premenopausal women, where the values were 63.3%, 70.7%, 74.4%, and 69.7% in the 20-mg, 10-mg, 5-mg, and 2.5-mg groups, respectively, and 32.9% at 1 mg and 29.7% on placebo. In postmenopausal women, the values were 41.9%, 36.7%, 33.3%, and 41.9% in the 20-mg, 10-mg, 5-mg, and 2.5-mg groups, with values of 44.2% in the 1-mg group and 43.8% in the placebo group.
The median density change was 18.5% in premenopausal women and 4.0% in postmenopausal women.
“We didn’t see anything in the postmenopausal women. The decrease for those on 20 milligrams and those on placebo were exactly the same. Why this is, we still don’t know because we do know that tamoxifen in the adjuvant setting could be used for postmenopausal women. It could be that 6 months is too short of a time [to see a benefit]. We don’t know,” said Dr. Hall, who is a medical epidemiologist and biostatistician at Karolinska Institutet, Stockholm, Sweden.
Severe vasomotor side effects like hot flashes, cold flashes, and night sweats were reduced by about 50% in the lower tamoxifen doses, compared with 20 mg.
Dr. Hall also pointed out that tamoxifen is a prodrug. The CYP2D6 enzyme produces a range of metabolites, with endoxifen having the strongest affinity to the estrogen receptor and being present at the highest plasma concentration. He showed a table of endoxifen plasma levels at various tamoxifen doses in women of various metabolizer status, ranging from poor to ultrafast. Among intermediate, normal, and ultrarapid metabolizers, 5- and 10-mg doses produced plasma endoxifen levels ranging from 2.4 to 6.2 ng/mL, which represents a good therapeutic window. “For intermediate and normal metabolizers, it could be that 5 mg [of tamoxifen] is enough, but I want to underline that we didn’t use breast cancer incidence or recurrence in this study, we used density change, so we should be careful when we use these results,” said Dr. Hall. His group is now conducting the KARISMA Endoxifen trial, which will test endoxifen directly at doses of 1 and 2 mg.
Dr. Cornell has no relevant financial disclosures. Dr. Hall is a member of the scientific advisory board for Atossa Therapeutics.
SAN ANTONIO — The drug can reduce incidence of breast cancer in high-risk individuals, but side effects that mimic menopause have led to low rates of uptake. Lower-dose tamoxifen aims to reduce those side effects, but there remains some uncertainty about the minimum dose required to maintain efficacy.
The TAM-01 study, first published in 2019, demonstrated that a 5-mg dose of tamoxifen led to a reduction in recurrence of invasive breast cancer or ductal carcinoma in situ (DCIS). At the San Antonio Breast Cancer Symposium, two studies were presented that provided insight into dose efficacy and likelihood of medication adherence in women taking baby TAM.
“We all know that women who are at increased risk for breast cancer may benefit from the use of tamoxifen to help lower their risk, although historical uptake to tamoxifen in the prevention setting has been quite low,” said Lauren Cornell, MD, during a presentation. Her team investigated the impact of patient counseling on how well they understood their risk, as well as their likelihood of adherence to the medication.
The study included 41 women, and 31 completed follow-up at 1 year. “We saw that 90% of our patients reported good or complete understanding of their breast cancer risk after the consultation, emphasizing the benefit of that consult, and 73% reported that the availability of baby tamoxifen helped in their decision to consider a preventative medication,” said Dr. Cornell during her presentation. After 1 year of follow-up, 74% said that they had initiated baby tamoxifen, and 78% of those who started taking the drug were still taking it at 1 year.
Participants who continued to take baby TAM at 1 year had a higher estimated breast cancer risk (IBIS 10-year risk, 12.7% vs 7.6%; P = .027) than those who discontinued. “We saw that uptake to baby TAM after informed discussion in patients who qualify is high, especially in those patients with high risk and intraepithelial lesions or DCIS, and adherence and tolerability at 1 year follow up is improved, compared to what we would expect with traditional dosing of tamoxifen.

Living in a Food Swamp Tied to High Breast Cancer Mortality
SAN ANTONIO — a novel ecological study has found.
“Food deserts and food swamps are both bad, but it’s worse in food swamps,” Malcolm Bevel, PhD, MSPH, with Augusta University in Georgia, said in an interview.
He presented his research at the San Antonio Breast Cancer Symposium.
Breast cancer is the fourth leading cause of cancer death in the United States and is one of 13 obesity-related cancers. Healthy food consumption is a protective factor shown to decrease obesity risk and postmenopausal breast cancer mortality.
However, residing in food deserts or food swamps reduces access to healthy foods and has been severely understudied regarding postmenopausal breast cancer mortality, Dr. Bevel explained.
To investigate, Dr. Bevel and colleagues did a cross-sectional, ecological analysis where they merged 2010 to 2020 postmenopausal breast cancer mortality data from the Centers for Disease Control and Prevention (CDC) with aggregated 2012 to 2020 data from the US Department of Agriculture Food Environment Atlas.
A food swamp score was calculated as the ratio of fast-food and convenience stores to grocery stores and farmer’s markets.
A food desert score was calculated as the proportion of residents living more than 1 mile (urban) or 10 miles (rural) from a grocery store and household income ≤ 200% of the federal poverty threshold.
The researchers categorized food deserts and food swamps as low, moderate, or high, with higher scores denoting counties with fewer resources for healthy food.
Counties with high postmenopausal breast cancer mortality rates had a higher percentage of non-Hispanic Black population (5.8% vs. 2.1%), poverty rates (17.2% vs 14.2%), and adult obesity (32.5% vs 32%) and diabetes rates (11.8% vs 10.5%), compared with counties with low postmenopausal breast cancer mortality rates, Dr. Bevel reported.
The age-adjusted odds of counties having high postmenopausal breast cancer mortality was 53% higher in counties with high food desert scores (adjusted odds ratio [aOR] 1.53; 95% CI, 1.26 - 1.88), and over twofold higher in those with high food swamp scores (aOR, 2.09; 95% CI: 1.69 - 2.58).
In fully adjusted models, the likelihood of counties having moderate postmenopausal breast cancer mortality rates was 32% higher in those with moderate food swamp scores (aOR, 1.32; 95% CI, 1.03 - 1.70).
Growing Epidemic Requires System Change
These findings are in line with another study by Dr. Bevel and his colleagues published earlier this year in JAMA Oncology.
In that study, communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, as reported by this news organization.
There is a “growing epidemic” of food deserts and food swamps in the US, which could be due to systemic issues such as gentrification/redlining and lack of investment with chain grocery stores that provide healthy food options, said Dr. Bevel.
Local policymakers and community stakeholders could implement culturally tailored, sustainable interventions for obesity and obesity-related cancer prevention, including postmenopausal breast cancer. These could include creating more walkable neighborhoods and community vegetable gardens, he suggested.
“This is an important study demonstrating how the environment impacts outcomes in postmenopausal women diagnosed with breast cancer,” said Lia Scott, PhD, MPH, discussant for the study.
“Most of the literature is primarily focused on food deserts to characterize the food environment. However, these authors looked at both food deserts and food swamps. And even after adjusting for various factors and age, counties with high food swamp scores at greater odds of having higher postmenopausal breast cancer mortality rates,” said Dr. Scott, who is from Georgia State University School of Public Health in Atlanta.
“There is a clear need for systems change. With ecological studies like this one, we could potentially drive policy by providing actionable data,” she added.
The study had no specific funding. Dr. Bevel and Dr. Scott report no relevant financial relationships.

Oncotype Score Helps Avoid Unnecessary Radiation in DCIS
SAN ANTONIO — There’s a long-standing concern among oncologists that many women with ductal carcinoma in situ (DCIS), a potential precursor to invasive breast cancer, receive more treatment than they need. The potential for overtreatment largely revolves around the extent of surgery and the use of radiation.
Using the Oncotype DX Breast DCIS Score test, a laboratory test that estimates DCIS recurrence risk, may help identify patients with low-risk DCIS who can safely avoid adjuvant radiation after surgery, according to new research (abstract GS03-01) presented at the San Antonio Breast Cancer Symposium.
Low-risk patients who skipped adjuvant radiotherapy after breast-conserving surgery demonstrated similar 5-year recurrence rates compared with high-risk patients who received adjuvant radiotherapy.
This is the first prospective study to evaluate radiation decisions among patients with DCIS.
Lead author Seema A. Khan, MD, who presented the research, called the findings “reassuring.”
However, “we need larger and better trials” as well as longer follow-up to confirm this less-is-more approach, said Dr. Khan, a breast cancer surgeon and researcher at Northwestern University, Chicago.
Virginia Kaklamani, MD, who moderated the presentation, noted that it is good to finally have prospective data on this topic. And although they are not definitive, “I personally think these results should be used” for counseling, said Dr. Kaklamani, leader of the breast cancer program at UT Health San Antonio.
To reduce the risk for DCIS recurrence or progression to invasive breast cancer, most patients with DCIS undergo breast-conserving surgery followed by adjuvant radiotherapy, Dr. Khan explained. Instead of breast-conserving surgery, about one in four patients opt for mastectomy.
Earlier results from this trial revealed that MRI helped identify patients who can safely receive breast-conserving surgery instead of mastectomy.
The current results assessed whether the Oncotype DX score can guide radiation treatment decisions.
The study included 171 patients with DCIS who had wide local excisions after MRI confirmed that they could forgo more extensive surgery.
Surgical specimens were then sent for testing to determine the DCIS score using the 12-gene Oncotype DX test.
Women who scored < 39 points on the 100-point Oncotype DX scale were considered to be at low risk for recurrence and were advised to skip radiation. Women who scored > 39 were advised to undergo radiation. Overall, 93% of the patients followed the radiation recommendations: 75 of 82 patients (91.4%) deemed as low risk skipped adjuvant radiotherapy and 84 of 89 patients (94.4%) deemed as high risk had radiotherapy.
At a median follow-up of 5 years, 5.1% (4 of 82) of low-risk patients experienced a recurrence vs. 4.5% (4 of 89) of higher-risk patients.
Recurrence rates among patients who followed the radiation recommendations mirrored these overall findings: 5.5% of 75 patients with low-risk DCIS who skipped radiotherapy experienced disease recurrence vs. 4.8% of 84 patients with high-risk DCIS who received radiotherapy.
Age did not appear to affect the outcomes. Among the 33 women younger than 50 years, two experienced a recurrence (4%), both invasive. One occurred in the low-risk group and the other in the higher-risk group. Among the 138 older women, six had recurrences, three in each group, and one recurrence in each was invasive.
In short, “women who skipped radiation based on this score did not experience an excess risk of” ipsilateral recurrence over 5 years, said Dr. Khan.
Overall, the study offers “strong evidence” that the DCIS score might help “prevent excessive treatment for some patients,” she concluded, adding that 10-year outcomes will be reported.
The work was funded by the National Cancer Institute. Dr. Khan has no conflicts of interest. Dr. Kaklamani has extensive industry ties, including being a speaker for Pfizer, Genentech, Novartis, and AstraZeneca.

Recurrence rates among patients who followed the radiation recommendations mirrored these overall findings: 5.5% of 75 patients with low-risk DCIS who skipped radiotherapy experienced disease recurrence vs. 4.8% of 84 patients with high-risk DCIS who received radiotherapy.
Age did not appear to affect the outcomes. Among the 33 women younger than 50 years, two experienced a recurrence (4%), both invasive. One occurred in the low-risk group and the other in the higher-risk group. Among the 138 older women, six had recurrences, three in each group, and one recurrence in each was invasive.
In short, “women who skipped radiation based on this score did not experience an excess risk of” ipsilateral recurrence over 5 years, said Dr. Khan.
Overall, the study offers “strong evidence” that the DCIS score might help “prevent excessive treatment for some patients,” she concluded, adding that 10-year outcomes will be reported.
The work was funded by the National Cancer Institute. Dr. Khan has no conflicts of interest. Dr. Kaklamani has extensive industry ties, including being a speaker for Pfizer, Genentech, Novartis, and AstraZeneca.

CGRP in migraine prodrome can stop headache, reduce severity
BARCELONA, SPAIN — In the randomized, placebo-controlled crossover PRODROME trial, treatment with ubrogepant (Ubrelvy) 100 mg, one of the new CGRP receptor antagonists, during the prodrome prevented the development of moderate/severe headache at both 24 hours and 48 hours post-dose. The medication also reduced headache of any intensity within 24 hours and functional disability compared with placebo.
“This represents a totally different way of treating a migraine attack – to treat it before the headache starts. This is a paradigm shift in the way we approach the acute treatment of migraine,” study investigator Peter Goadsby, MBBS, MD, PhD, professor of neurology at Kings College London, UK, said in an interview.
The findings were presented at 17th European Headache Congress (EHC) and were also recently published online in The Lancet.
A New Way to Manage Migraine?
The prodrome is usually the earliest phase of a migraine attack and is believed to be experienced by the vast majority of patients with migraine. It consists of various symptoms, including sensitivity to light, fatigue, mood changes, cognitive dysfunction, craving certain foods, and neck pain, which can occur several hours or days before onset.
Dr. Goadsby notes that, at present, there isn’t very much a patient can do about the prodrome.
“We advise patients if they feel an attack is coming not to do anything that might make it worse and make sure they have their acute treatment available for when the headache phase starts. So, we just advise people to prepare for the attack rather than doing anything specific to stop it. But with new data from this study, we now have something that can be done. Patients have an option,” he said.
Dr. Goadsby explained that currently patients are not encouraged to use acute migraine medications such as triptans in the prodrome phase.
“There is actually no evidence that taking a triptan during the prodromal phase works. The advice is to take a triptan as soon as the headache starts, but not before the headache starts.”
He noted that there is also the problem of medication overuse that is seen with triptans, and most other medications used to treat acute migraine, which leads to medication overuse headache, “so we don’t like to encourage patients to increase the frequency of taking triptans for this reason.”
But ubrogepant and other members of the “gepant” class do not seem to have the propensity for medication overuse problems. “Rather, the more a patient takes the less likely they are to get a headache as these drugs also have a preventative effect,” Dr. Goadsby said.
Major Reduction in Severity
The PRODROME trial was conducted at 75 sites in the United States in 518 patients who had at least a 1-year history of migraine with or without aura and a history of two to eight migraine attacks per month with moderate to severe headache in each of the 3 months before study entry.
Participants underwent a rigorous screening period during which they were required to show that they could identify prodromal symptoms that were reliably followed by migraine headache within 1-6 hours.
They were randomly assigned to receive either placebo to treat the first qualifying prodrome event and ubrogepant 100 mg to treat the second qualifying prodrome event or vice versa, with instructions to take the study drug at the onset of the prodrome event.
Efficacy assessments during the double-blind treatment period were recorded by the participant in an electronic diary. On identifying a qualifying prodrome, the patient recorded prodromal symptoms, and was then required to report the absence or presence of a headache at regular intervals up to 48 hours after the study drug dose. If a headache was reported, participants rated the intensity as mild, moderate, or severe and reported whether rescue medication was taken to treat it.
The primary endpoint was absence of moderate or severe intensity headache within 24 hours after study-drug dose. This occurred after 46% of 418 qualifying prodrome events that had been treated with ubrogepant and after 29% of 423 qualifying prodrome events that had been treated with placebo (odds ratio, 2.09; 95% CI, 1.63 - 2.69; P < .0001).
“The incidence of moderate to severe headache was almost halved when ubrogepant was taken in the prodrome,” Dr. Goadsby reported.
Ubrogepant also showed similar impressive results for the secondary endpoints in the absence of moderate to severe headache within 48 hours post-dose and the absence of any headache of any intensity at 24 hours.
Little to No Disability
The researchers also evaluated functional ability, and more participants reported “no disability or able to function normally” during the 24 hours after treatment with ubrogepant than after placebo (OR, 1.66; P < .0001).
Other findings showed that the prodromal symptoms themselves, such as light sensitivity and cognitive dysfunction, were also reduced with ubrogepant.
Dr. Goadsby said he was pleased but not surprised by the results, as the “gepant” class of drugs are used in both the acute treatment of migraine and as preventive agents, although different agents have been approved for different indications in this regard.
“The ‘gepants’ are a class of medication that can be used in almost any way in migraine — to treat an acute migraine headache, to prevent migraine if taken chronically, and now we see that they can also stop a migraine from developing if taken during the initial prodromal phase. That’s unique for a migraine medication,” he said.
While the current study was conducted with ubrogepant, Dr. Goadsby suspects that any of the “gepants” would probably have a similar effect.
He noted that the prodromal phase of migraine has only just started to be explored, with functional imaging studies showing that structural brain changes occur during this phase.
Dr. Goadsby said the current study opens up a whole new area of interest, emphasizing the clinical value of identifying the prodrome in individuals with migraine, better characterizing the symptomology of the prodrome and understanding more about how to treat it.
“It’s the ultimate way of treating migraine early, and by taking this type of medication in the prodromal phase, patients may be able to stop having pain. That’s quite an implication,” he concluded.
The PRODROME study was funded by AbbVie. Dr. Goadsby reports personal fees from AbbVie.

Is migraine really a female disorder?
BARCELONA, SPAIN — Migraine is widely considered a predominantly female disorder. Its frequency, duration, and severity tend to be higher in women, and women are also more likely than men to receive a migraine diagnosis. However, gender expectations, differences in the likelihood of self-reporting, and problems with how migraine is classified make it difficult to estimate its true prevalence in men and women.
Different Symptoms
Headache disorders are estimated to affect 50% of the general population ; tension-type headache and migraine are the two most common. According to epidemiologic studies, migraine is more prevalent in women, with a female-to-male ratio of 3:1. There are numerous studies of why this might be, most of which focus largely on female-related factors, such as hormones and the menstrual cycle.
“Despite many years of research, there isn’t one clear factor explaining this substantial difference between women and men,” said Tobias Kurth of Charité – Universitätsmedizin Berlin, Germany. “So the question is: Are we missing something else?”
One factor in these perceived sex differences in migraine is that women seem to report their migraines differently from men, and they also have different symptoms. For example, women are more likely than men to report severe pain, and their migraine attacks are more often accompanied by photophobia, phonophobia, and nausea, whereas men’s migraines are more often accompanied by aura.
“By favoring female symptoms, the classification system may not be picking up male symptoms because they’re not being classified in the right way,” Dr. Kurth said, with one consequence being that migraine is underdiagnosed in men. “Before trying to understand the biological and behavioral reasons for these sex differences, we first need to consider these methodological challenges that we all apply knowingly or unknowingly.”
Christian Lampl, professor of neurology at Konventhospital der Barmherzigen Brüder Linz, Austria, and president of the European Headache Federation, said in an interview, “I’m convinced that this 3:1 ratio which has been stated for decades is wrong, but we still don’t have the data. The criteria we have [for classifying migraine] are useful for clinical trials, but they are useless for determining the male-to-female ratio.
“We need a new definition of migraine,” he added. “Migraine is an episode, not an attack. Attacks have a sudden onset, and migraine onset is not sudden — it is an episode with a headache attack.”
Inadequate Menopause Services
Professor Anne MacGregor of St. Bartholomew’s Hospital in London, United Kingdom, specializes in migraine and women’s health. She presented data showing that migraine is underdiagnosed in women; one reason being that the disorder receives inadequate attention from healthcare professionals at specialist menopause services.
Menopause is associated with an increased prevalence of migraine, but women do not discuss headache symptoms at specialist menopause services, Dr. MacGregor said.
She then described unpublished results from a survey of 117 women attending the specialist menopause service at St. Bartholomew’s Hospital. Among the respondents, 34% reported experiencing episodic migraine and an additional 8% reported having chronic migraine.
“Within this population of women who were not reporting headache as a symptom [to the menopause service until asked in the survey], 42% of them were positive for a diagnosis of migraine,” said Dr. MacGregor. “They were mostly relying on prescribed paracetamol and codeine, or buying it over the counter, and only 22% of them were receiving triptans.
“They are clearly being undertreated,” she added. “Part of this issue is that they didn’t spontaneously report headache as a menopause symptom, so they weren’t consulting for headache to their primary care physicians.”
Correct diagnosis by a consultant is a prerequisite for receiving appropriate migraine treatment. Yet, according to a US study published in 2012, only 45.5% of women with episodic migraine consulted a prescribing healthcare professional. Of those who consulted, 89% were diagnosed correctly, and only 68% of those received the appropriate treatment.
A larger, more recent study confirmed that there is a massive unmet need for improving care in this patient population. The Chronic Migraine Epidemiology and Outcomes (CaMEO) Study, which analyzed data from nearly 90,000 participants, showed that just 4.8% of people with chronic migraine received consultation, correct diagnosis, and treatment, with 89% of women with chronic migraine left undiagnosed.
The OVERCOME Study further revealed that although many people with migraine were repeat consulters, they were consulting their physicians for other health problems.
“This makes it very clear that people in other specialties need to be more aware about picking up and diagnosing headache,” said MacGregor. “That’s where the real need is in managing headache. We have the treatments, but if the patients can’t access them, they’re not much good to them.”
