No Benefit to Salvage Transplant in R/R Multiple Myeloma
Patients receiving a second, salvage-autologous stem cell transplant alongside lenalidomide-dexamethasone maintenance therapy did not demonstrate improved progression-free survival (PFS) or overall survival compared with patients who continued the two-drug regimen without salvage transplant, according to research presented at the American Society of Hematology annual meeting.
The primary phase 3 analysis, published in 2021, showed no survival benefit following salvage transplant at the time of relapse, though it only followed patients for a median of 37 months.
However, because a significant fraction of patients in the transplant arm — about 29% — did not undergo the planned salvage transplant before dropping out of the study, the researchers performed further analyses that “suggested a survival benefit in patients who actually received the transplant,” first author Marc-Andrea Baertsch, MD, of the German Cancer Research Center and University Hospital Heidelberg, reported at ASH.
Now, the latest analysis, which followed patients for a median of 99 months (8.25 years), confirmed the initial 2021 findings, Dr. Baertsch explained.
“The writing on the wall is clear: Don’t repeat a transplant at the time of relapse for those who have already gotten a transplant,” said Manni Mohyuddin, MD, of the University of Utah in Salt Lake City, who was not involved in the research. Dr. Mohyuddin added, however, that this finding doesn’t apply to those who haven’t yet gotten a transplant. “Data from other trials suggests a role of transplant in this situation, depending on the unique circumstances.”
The current trial included 282 adult patients, aged 75 years or younger, with relapsed or refractory multiple myeloma. Between 2010 and 2016, patients in the intention-to-treat analysis (n = 277) were randomized to lenalidomide-dexamethasone reinduction and maintenance, along with salvage high-dose chemotherapy with melphalan and autologous stem cell transplantation (n = 139) or just continuous lenalidomide-dexamethasone until progression (n = 138).
Patients in both arms received three cycles of lenalidomide-dexamethasone up front: 25 mg of lenalidomide on days 1 through 21, and 40 mg of dexamethasone on days 1, 8, 15, and 22 in 4-week cycles. Those in the salvage transplant arm then received high-dose chemotherapy with 200 mg/m2 of melphalan followed by transplant and 10 mg of lenalidomide maintenance therapy daily, while those in the control arm continued with receiving lenalidomide-dexamethasone.
All patients had received one to three prior lines of therapy, had good performance status, and had a time-to-disease-progression of at least 12 months after frontline autologous stem cell transplant.
In the primary 2021 study, patients in the salvage transplant group did not demonstrate a survival benefit (hazard ratio [HR] for PFS, 0.87; HR for overall survival, 0.81).
In the latest analysis, no survival benefit emerged after following patients for a median of about 8 years. Patients in the salvage transplant arm had a median PFS of 20.5 months vs 19.3 months in the continuous therapy arms (HR, 0.98; 95% CI, 0.76-1.27; P = .9). Median overall survival was 67.1 months in the salvage transplant arm and 62.7 months in the continuous treatment arm (HR, 0.89; 95% CI, 0.66 - 1.20; P = .44).
Time to first progression after frontline transplant was associated with a PFS benefit but did not predict an overall survival benefit, Dr. Baertsch noted.
When evaluating outcomes from the time of salvage transplant to account for the high number of dropouts, the PFS and overall survival findings held. Patients who received salvage transplant did not experience significantly improved PFS (HR, 0.91) or overall survival (76.3 months in the salvage group vs 65.9 months in the continuous treatment arm; HR, 0.80).
The lack of PFS and overall survival benefit occurred across all myeloma subgroups, Dr. Baertsch said.
Overall, the results indicate that “ a repeat transplant at the time of relapse for patients who had already gotten a transplant previously was no better than continuing a two-drug regimen,” Dr. Mohyuddin said.
However, he noted, “a lot has changed for myeloma care” since this trial was initially conducted. “We now have better regimens available that do not involve a transplant. If a repeat transplant couldn’t beat a two-drug regimen, it surely cannot beat a three drug or four drug regimen.”

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.

CAR T-Cell Therapy: Cure for Systemic Autoimmune Diseases?
A single infusion of autologous CD19-directed CAR T-cell therapy led to persistent, drug-free remission in 15 patients with life-threatening systemic lupus erythematosus, idiopathic inflammatory myositis, or systemic sclerosis, according to research presented at the American Society of Hematology annual meeting.
The responses persisted at 15 months median follow-up, with all patients achieving complete remission, reported Fabian Mueller, MD, of the Bavarian Cancer Research Center and Friedrich-Alexander University of Erlangen-Nuremberg, Bavaria, Germany.
The CAR T-cell treatment appears to provide an “entire reset of B cells,” possibly even a cure, for these 15 patients who had run out of treatment options and had short life expectancies, Dr. Mueller said. “It’s impressive that we have treated these patients.”
Some of the cases have been described previously — including in Annals of the Rheumatic Diseases earlier this year, Nature Medicine in 2022, and the New England Journal of Medicine in 2021.
Now with substantially longer follow-up, the investigators have gained a greater understanding of “the B-cell biology behind our treatment,” Dr. Mueller said. However, “we need longer follow-up to establish how effective the treatment is going to be in the long run.”
All 15 patients included in the analysis were heavily pretreated and had multi-organ involvement. Prior to CAR T-cell therapy, patients had a median disease duration of 3 years, ranging from 1 to as many as 20 years, and had failed a median of five previous treatments. Patients were young — a median age of 36 years — which is much younger than most oncology patients who undergo CAR T-cell therapy, Dr. Mueller said.
The 15 patients underwent typical lymphodepletion and were apheresed and treated with a single infusion of 1 x 106 CD19 CAR T cells per kg of body weight — an established safe dose used in a phase 1 trial of B cell malignancies.
The CAR T cells, manufactured in-house, expanded rapidly, peaking around day 9. B cells disappeared within 7 days and began to reoccur in peripheral blood in all patients between 60 and 180 days. However, no disease flares occurred, Dr. Mueller said.
After 3 months, eight patients with systemic lupus erythematosus showed no sign of disease activity and dramatic improvement in symptoms. Three patients with idiopathic inflammatory myositis experienced major improvements in symptoms and normalization of creatinine kinase levels, the most clinically relevant marker for muscle inflammation. And three of four patients with systemic sclerosis demonstrated major improvements in symptoms and no new disease activity. These responses lasted for a median of 15 months, and all patients stopped taking immunosuppressive drugs.
Patients also tolerated the CAR T-cell treatment well, especially compared with the adverse event profile in oncology patients. Only low-grade inflammatory CAR T-related side effects occurred, and few patients required support for B-cell-derived immune deficiency.
However, infectious complications occurred in 14 patients, including urinary tract and respiratory infections, over the 12-month follow-up. One patient was hospitalized for severe pneumonia a few weeks after CAR T therapy, and two patients experienced herpes zoster reactivations, including one at 6 months and one at 12 months following treatment.
During a press briefing at the ASH conference, Dr. Mueller addressed the “critical question” of patient selection for CAR T-cell therapy, especially in light of the recently announced US Food and Drug Administration investigation exploring whether CAR T cells can cause secondary blood cancers.
Although the T-cell malignancy risk complicates matters, CAR T cells appear to behave differently in patients with autoimmune diseases than those with cancer, he said.
“We don’t understand the biology” related to the malignancy risk yet, Dr. Mueller said, but the benefit for end-of-life patients with no other treatment option likely outweighs the risk. That risk-benefit assessment, however, is more uncertain for those with less severe autoimmune diseases.
For now, it’s important to conduct individual assessments and inform patients about the risk, Dr. Mueller said.
Dr. Mueller disclosed relationships with BMS, AstraZeneca, Gilead, Janssen, Miltenyi Biomedicine, Novartis, Incyte, Abbvie, Sobi, and BeiGene.

“We don’t understand the biology” related to the malignancy risk yet, Dr. Mueller said, but the benefit for end-of-life patients with no other treatment option likely outweighs the risk. That risk-benefit assessment, however, is more uncertain for those with less severe autoimmune diseases.
For now, it’s important to conduct individual assessments and inform patients about the risk, Dr. Mueller said.

A single infusion of autologous CD19-directed CAR T-cell therapy led to persistent, drug-free remission in 15 patients with life-threatening systemic lupus erythematosus, idiopathic inflammatory myositis, or systemic sclerosis, according to research presented at the American Society of Hematology annual meeting.
The responses persisted at 15 months median follow-up, with all patients achieving complete remission, reported Fabian Mueller, MD, of the Bavarian Cancer Research Center and Friedrich-Alexander University of Erlangen-Nuremberg, Bavaria, Germany.
The CAR T-cell treatment appears to provide an “entire reset of B cells,” possibly even a cure, for these 15 patients who had run out of treatment options and had short life expectancies, Dr. Mueller said. “It’s impressive that we have treated these patients.”
Some of the cases have been described previously — including in Annals of the Rheumatic Diseases earlier this year, Nature Medicine in 2022, and the New England Journal of Medicine in 2021.
Now with substantially longer follow-up, the investigators have gained a greater understanding of “the B-cell biology behind our treatment,” Dr. Mueller said. However, “we need longer follow-up to establish how effective the treatment is going to be in the long run.”
All 15 patients included in the analysis were heavily pretreated and had multi-organ involvement. Prior to CAR T-cell therapy, patients had a median disease duration of 3 years, ranging from 1 to as many as 20 years, and had failed a median of five previous treatments. Patients were young — a median age of 36 years — which is much younger than most oncology patients who undergo CAR T-cell therapy, Dr. Mueller said.
The 15 patients underwent typical lymphodepletion and were apheresed and treated with a single infusion of 1 x 106 CD19 CAR T cells per kg of body weight — an established safe dose used in a phase 1 trial of B cell malignancies.
The CAR T cells, manufactured in-house, expanded rapidly, peaking around day 9. B cells disappeared within 7 days and began to reoccur in peripheral blood in all patients between 60 and 180 days. However, no disease flares occurred, Dr. Mueller said.
After 3 months, eight patients with systemic lupus erythematosus showed no sign of disease activity and dramatic improvement in symptoms. Three patients with idiopathic inflammatory myositis experienced major improvements in symptoms and normalization of creatinine kinase levels, the most clinically relevant marker for muscle inflammation. And three of four patients with systemic sclerosis demonstrated major improvements in symptoms and no new disease activity. These responses lasted for a median of 15 months, and all patients stopped taking immunosuppressive drugs.
Patients also tolerated the CAR T-cell treatment well, especially compared with the adverse event profile in oncology patients. Only low-grade inflammatory CAR T-related side effects occurred, and few patients required support for B-cell-derived immune deficiency.
However, infectious complications occurred in 14 patients, including urinary tract and respiratory infections, over the 12-month follow-up. One patient was hospitalized for severe pneumonia a few weeks after CAR T therapy, and two patients experienced herpes zoster reactivations, including one at 6 months and one at 12 months following treatment.

FDA greenlights iptacopan to treat paroxysmal nocturnal hemoglobinuria
Iptacopan, a factor B inhibitor, offers “superior hemoglobin improvement in the absence of transfusions” in patients with this rare chronic blood disorder, according to a Novartis press release.
“An efficacious oral treatment with a demonstrated safety profile could be practice-changing for physicians and help relieve burdens experienced by people with PNH,” Vinod Pullarkat, MD, of City of Hope Cancer Center, Duarte, California, said in the company press release.
Previously, the only approved treatments for PNH were injectable C5 complement inhibitors.
The latest approval was based on the randomized, open-label, phase 3 APPLY-PNH trial in 97 adults with PNH and anemia and was supported by safety and efficacy findings from the phase 3, single-arm APPOINT-PNH study in 40 C5 complement inhibitor–naive patients.
APPLY-PNH participants included adults with residual anemia receiving a stable regimen of anti-C5 treatment in the prior 6 months. Patients were randomly assigned to switch to 200 mg of iptacopan (n = 62) given twice daily or to remain on the anti-C5 therapy (n = 35).
The investigators reported greater increases in hemoglobin levels in patients who switched to iptacopan, with sustained increases ≥ 2 g/dL in 82.3% compared with 0% of patients who did not switch. Investigators also observed increases ≥ 12 g/dL in 67.7% of patients who switched vs 0% of those who did not. Almost all patients (95.2%) in the iptacopan group avoided a red blood cell transfusion vs 45.7% among patients who did not switch.
In the APPLY-PNH trial, common adverse reactions with iptacopan vs anti-C5 therapy included headache(19% vs 3%), nasopharyngitis (16% vs 17%), diarrhea (15% vs 6%), abdominal pain (15% vs 3%), bacterial infection(11% vs 11%), nausea (10% vs 3%), and viral infection(10% vs. 31%). Two patients experienced serious adverse events, which included pyelonephritis, urinary tract infection, and COVID-19.
In the APPOINT-PNH trial, the most common adverse events were headache (28%), viral infection (18%), nasopharyngitis (15%), and rash (10%). Serious adverse events, reported in two patients (5%), included COVID-19 and bacterial pneumonia.
“Fabhalta may cause serious infections caused by encapsulated bacteria and is available only through a Risk Evaluation and Mitigation Strategy (REMS) that requires vaccinations for encapsulated bacteria,” Novartis cautioned.

How to address chemo-related amenorrhea in early breast cancer to help improve quality of life
in a large multicenter French cohort study.
The findings, which showed a particularly increased risk of persistent CRA in older women and those who received adjuvant tamoxifen, can help inform communication, personalized counseling, and supportive care, according to the investigators.
At 1 year after treatment, CRA occurred in 1242 of 1497 women (83.0%) from the prospective, longitudinal Cancers Toxicity Study (CANTO). The rates at years 2 and 4 after treatment were 72.5% and 66.1%, respectively, Rayan Kabirian, MD, of Gustave Roussy, Villejuif, France, and Sorbonne University, Paris, and colleagues reported.
In a quality-of-life analysis conducted among 729 women from the cohort, 416 (57.1%) had persistent CRA, although 11 of 21 women aged 18-34 years who had no menses at year 2 had late menses recovery between years 2 and 4. Those with persistent CRA at year 4, compared with those who had menses recovery at any time, had significantly worse insomnia (mean difference, 9.9 points), worse systemic therapy-related adverse effects (mean difference, 3.0 points), and worse sexual functioning (mean difference, -9.2 points).
Factors associated with greater risk of persistent CRA included receipt versus non-receipt of adjuvant tamoxifen (adjusted odds ratio, 1.97), and hot flashes at diagnosis (aOR, 1.83, and older age versus age 18-34 (aORs, 1.84 for those aged 35-39 years; 5.90 for those aged 40-44 years, and 21.29 for those 45 or older).
The findings were published online November 16 in JAMA Network Open.
The study cohort included 1636 women under age 50 years (mean age of 42.2 years) at the time of diagnosis of stage I to III breast cancer. Outcomes at up to 4 years after diagnosis and enrollment between 2012 and 2017 were reported. QOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires c30 and br23.
“Breast cancer is the most commonly diagnosed tumor in women, and approximately 20% of women with breast cancer are younger than 50 years at diagnosis,” the investigators note, explaining that younger survivors have higher risk of cancer-related symptoms and quality-of-life deterioration. “In particular, treatment-related symptoms linked to the menopausal transition (ie, vasomotor symptoms and sexual problems) represent an important source of distress during and after treatment, highlighting a need to monitor and address survivorship-related problems that are specific to this population.”
The current analysis “helps answer several clinical questions about long-term trajectories of CRA and menses recovery rates by age and about factors associated with higher likelihood of CRA,” they added, noting that the findings have several clinical implications.
For example, premenopausal women should be made aware of the risks associated with chemotherapy-related premature ovarian failure and persistent CRA, and should and receive systematic oncofertility counseling, they argue.
“In addition, in light of data showing possible late [menses] recoveries, contraceptive options should also be clearly discussed,” and “[d]edicated gynecological counseling may help patients who have an inaccurate perception of infertility due to previous exposure to chemotherapy and long-term absence of menses.”
Given that a late menses recovery pattern was also observed in older age groups in the cohort, the investigators noted that choosing the optimal adjuvant endocrine treatment can pose a challenge.
“The absence of menses after completion of chemotherapy should not be used as a proxy for permanent transition to menopause, because it does not represent a reliable surrogate of gonadotoxicity,” they warned. “Adjuvant endocrine treatment choices should be based on a more thorough and comprehensive evaluation, combining absence of menses, assessments of circulating hormone levels, and gynecological ultrasonographic imaging.”
These findings “can inform personalized care pathways targeting patients at higher risk of QOL deterioration associated with a permanent menopausal transition,” they noted, concluding that “[r]isk and duration of CRA, including potential late resumption of menses and its downstream implications for QOL, should be approached using a coordinated biopsychosocial model addressing multiple dimensions of physical, psychological, and social health.
“Proactive management of premenopausal women with early breast cancer undergoing chemotherapy should also include adapted strategies for risk communication, as well as personalized counseling and early supportive care referrals.”

FDA investigates secondary cancers from CAR T-cell therapies
Secondary cancers are a known risk for this class of immunotherapies, known as B-cell maturation antigen (BCMA)–directed or CD19-directed autologous CAR T-cell therapies, and are included in the prescribing information for these drugs. However, the FDA has received 19 reports of secondary cancers, including CAR-positive lymphoma, since 2017, when the first CAR T-cell treatments were approved, according to Endpoints News.
Most of these reports came from the FDA’s postmarketing adverse event system and others from clinical trial data.
Although the overall benefits of these products continue to outweigh their potential risks, “FDA is investigating the identified risk of T-cell malignancy with serious outcomes, including hospitalization and death, and is evaluating the need for regulatory action,” the agency said in a press release.
Currently approved products in this class include idecabtagene vicleucel (Abecma), lisocabtagene maraleucel (Breyanzi), ciltacabtagene autoleucel (Carvykti), tisagenlecleucel (Kymriah), brexucabtagene autoleucel (Tecartus), and axicabtagene ciloleucel (Yescarta).
“Patients and clinical trial participants receiving treatment with these products should be monitored life-long for new malignancies,” the FDA added.
Suspected adverse events, including T-cell cancers, should be reported by contacting the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

FDA OKs capivasertib for certain advanced breast cancers
Specifically, the first-in-class AKT kinase inhibitor approval is for patients with one or more PIK3CA/AKT1/PTEN alterations, as detected by an FDA-approved test, whose metastatic disease progressed on at least one endocrine-based regimen or who experienced recurrence on or within 12 months of completing adjuvant therapy, according to the FDA approval announcement.
The FDA also approved a companion diagnostic device, the FoundationOne CDx assay, to identify patients who are eligible for treatment with capivasertib.
Approval of capivasertib was based on findings from the randomized, placebo-controlled, phase 3 CAPItello-291 trial, which involved 708 patients with locally advanced or metastatic HR-positive, HER2-negative breast cancer, including 289 whose tumors had PIK3CA/AKT1/PTEN alterations. All had progressed on aromatase inhibitor–based treatment and may have received up to two prior lines of endocrine therapy and up to one line of chemotherapy.
Patients were randomized to either 400 mg of oral capivasertib or placebo twice daily for 4 days, followed by 3 days off treatment each week over a 28-day treatment cycle. Patients in both arms received 500 mg intramuscular fulvestrant on cycle 1 days 1 and 15, and then every 28 days thereafter. Treatment continued until disease progression or unacceptable toxicity.
In the 289 patients with PIK3CA/AKT1/PTEN–altered tumors, median progression-free survival (PFS) in the capivasertib arm was 7.3 months versus 3.1 months in the placebo group (hazard ratio, 0.50).
An exploratory analysis of PFS in the 313 (44%) patients whose tumors did not have a PIK3CA/AKT1/PTEN alteration demonstrated a less notable benefit to the combination (HR, 0.79; 95% confidence interval, 0.61-1.02), indicating that “the difference in the overall population was primarily attributed to the results seen in the population of patients whose tumors have PIK3CA/AKT1/PTEN alteration,” the FDA explained.
Adverse reactions occurring in at least 20% of patients included decreased lymphocytes, leukocytes, hemoglobin, and neutrophils; increased fasting glucose, creatinine, and triglycerides; and diarrhea, nausea, fatigue, vomiting, and stomatitis.
The recommended capivasertib dose is 400 mg orally twice daily, given about 12 hours apart with or without food, for 4 days followed by 3 off days until disease progression or unacceptable toxicity, according to the prescribing information.

Patients were randomized to either 400 mg of oral capivasertib or placebo twice daily for 4 days, followed by 3 days off treatment each week over a 28-day treatment cycle. Patients in both arms received 500 mg intramuscular fulvestrant on cycle 1 days 1 and 15, and then every 28 days thereafter. Treatment continued until disease progression or unacceptable toxicity.
In the 289 patients with PIK3CA/AKT1/PTEN–altered tumors, median progression-free survival (PFS) in the capivasertib arm was 7.3 months versus 3.1 months in the placebo group (hazard ratio, 0.50).
An exploratory analysis of PFS in the 313 (44%) patients whose tumors did not have a PIK3CA/AKT1/PTEN alteration demonstrated a less notable benefit to the combination (HR, 0.79; 95% confidence interval, 0.61-1.02), indicating that “the difference in the overall population was primarily attributed to the results seen in the population of patients whose tumors have PIK3CA/AKT1/PTEN alteration,” the FDA explained.
Adverse reactions occurring in at least 20% of patients included decreased lymphocytes, leukocytes, hemoglobin, and neutrophils; increased fasting glucose, creatinine, and triglycerides; and diarrhea, nausea, fatigue, vomiting, and stomatitis.
The recommended capivasertib dose is 400 mg orally twice daily, given about 12 hours apart with or without food, for 4 days followed by 3 off days until disease progression or unacceptable toxicity, according to the prescribing information.

Specifically, the first-in-class AKT kinase inhibitor approval is for patients with one or more PIK3CA/AKT1/PTEN alterations, as detected by an FDA-approved test, whose metastatic disease progressed on at least one endocrine-based regimen or who experienced recurrence on or within 12 months of completing adjuvant therapy, according to the FDA approval announcement.
The FDA also approved a companion diagnostic device, the FoundationOne CDx assay, to identify patients who are eligible for treatment with capivasertib.

FDA approves first tx for rare, deadly clotting disorder
Congenital TTP affects fewer than 1,000 people in the United States and is caused by a mutation in the ADAMTS13 gene, which makes an enzyme that regulates blood clotting. Patients with the congenital TTP typically receive prophylactic plasma-based therapy to replenish the ADAMTS13 enzyme and reduce the risk for clotting and bleeding. The condition, however, can be fatal if left untreated.
The new agent is a purified recombinant form of the ADAMTS13 enzyme that works by replacing low levels of the deficient enzyme in patients with congenital TTP. Adzynma is given prophylactically to reduce the risk for disease symptoms and on demand when a patient is experiencing an acute event, according to the FDA approval announcement.
The approval was based on a global randomized phase 3 study comparing the product with plasma-based therapies in 46 patients with congenital TTP. Patients in the trial were randomized to receive 6 months of treatment with either intravenous Adzynma — given once every other week as prophylactic enzyme replacement therapy or once daily as on-demand enzyme replacement therapy — or plasma-based therapies. The patients then crossed over to the other treatment for 6 months.
Interim findings from the study showed that Adzynma reduced the incidence of thrombocytopenia — the most common symptom of congenital TTP — by 60% compared with plasma-based therapy (rate ratio, 0.40). No patients experienced an acute TTP event during Adzynma prophylaxis, Takeda said.
Significantly more patients receiving plasma-based therapies experienced treatment-emergent adverse events compared with those receiving the biologic.
The most common side effects associated with the biologic were headache (31.3%), diarrhea (16.7%), migraine (14.6%), abdominal pain (12.5%), nausea (12.5%), upper respiratory tract infection (12.5%), dizziness (10.4%), and vomiting (10.4%). No treatment-related adverse events, including allergic reactions, were observed during administration.
“The FDA remains deeply committed in our efforts to help facilitate the development and approval of safe and effective therapies for patients with rare diseases,” Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, stated. The “approval reflects important progress in the development of much-needed treatment options for patients affected by this life-threatening disorder.”

Prior authorizations interfere with recommended cancer care
Of 178 respondents with a prior authorization (PA) experience, 39 (22%) did not receive the care recommended by their treatment team because of a PA requirement, and 123 (69%) experienced a delay in receiving the recommended care, Fumiko Chino, MD, of Memorial Sloan Kettering Cancer Center, New York, and colleagues reported.
Reasons for not receiving recommended care included complete denial by the insurance company (26 of 39 patients), and a change in treatment plan because of initial denial (13 of 39 patients). Delays in receiving recommended care were 2 or more weeks for 90 of 123 patients, and 1 month or more in 40 of 123 patients.
Delays in receiving recommended care were associated with increased patient anxiety, a negative perception of the PA process, and patient administrative burden, the investigators noted.
The findings, which capture patient-based perspectives in the ongoing PA debacle, were reported online in JAMA Network Open.
“Prior authorization requires clinicians and patients to navigate a complex approval pathway. Resultant delays and denial can be particularly problematic for patients with cancer, who often need urgent treatment or symptom management,” the investigators explained. “Focusing on patient experiences with PA highlights a missing perspective in policy discussions and suggests another potential factor associated with eroding trust in the health care system.”
To assess the impact of PA, they conducted an anonymous survey using a convenience sample of patients with any cancer-related PA experience from July 1 to Oct. 6, 2022. Mean self-reported PA-related anxiety scores were 74.7 on a scale of 0-100, whereas usual anxiety scores were 37.5.
PA-related anxiety scores were significantly correlated with the length of treatment delay (P = .04), time spent on PA (P < .001), and overall PA experience (P < .001).
“Dealing with PA issues adds an extra layer of stress, which is known to increase anxiety and can worsen treatment-related and disease-related symptoms and adverse effects,” the investigators noted.
PA issues also eroded trust: 89% of respondents trusted their insurance company less, and 83% trusted the health care system less after a PA experience. Patient involvement in the PA process increased the likelihood of such distrust and of having a negative experience.
Of the 178 respondents, most were women (88%), non-Hispanic White individuals (84%), college graduates (84%), and young (18-39 years, 41%; 40-54 years, 33%). Most (67%) had to personally become involved in the PA process by calling their insurance or filing an appeal.
The investigators noted that “efforts to create national health policy solutions that streamline PA and make the process more transparent have been a major lobbying effort of large oncology societies,” and that bipartisan legislation to “establish regulations on the quality and timeliness of PA in the Medicare Advantage population” has stalled.
“In the meantime, the Centers for Medicare & Medicaid Services acted directly by issuing a final rule in April 2023 aimed at improving PA processes within the Medicare Advantage population by 2024,” they wrote, adding that “streamlining the PA process is key to optimizing the quality of care delivered and improving patients’ experience with cancer care.
“Policy interventions will be necessary to reform the PA process, as will advocacy efforts at the patient, clinician, and hospital level,” they concluded.

T-DXd benefits persist for HER2-low breast cancer
and low HER2 expression in the randomized phase 3 DESTINY-Breast04 study, according to 32-month follow-up data.
The overall safety profile of the HER2-directed antibody drug conjugate was also comparable to that observed at the primary analysis in 2022, and longer exposure did not appear to increase toxicity, Shanu Modi, MD, reported on behalf of the DESTINY-Breast04 investigators at the European Society of Medical Oncology (ESMO) Congress 2023.
“These results continue to support the use of T-DXd as the new standard of care after one line of chemotherapy in patients with HER2-low metastatic breast cancer,” said Dr. Modi, a breast oncologist and attending physician at Memorial Sloan Kettering Cancer Center, New York.
DESTINY-Breast04 enrolled 557 patients 2:1 to receive 5.4 mg/kg of T-DXd every 3 weeks or physicians’ choice of capecitabine, eribulin, gemcitabine, paclitaxel, or nab-paclitaxel, and established HER2-low mBC as “a new targetable patient population with T-DXd as a new standard of care,” she explained.
Median overall survival (mOS) with a median of 18.4 months of follow-up at the Jan. 11, 2022, primary data cut-off was 23.4 months in the T-DXd arm versus 16.8 months in the TPC arm and 23.9 versus 17.5 months, respectively, in the hormone receptor–positive (HR+) cohort (hazard ratio, 0.64 for both groups). At the preplanned extended follow-up with data cut-off on March 1, 2023, the mOS was 22.9 versus 16.8 months for T-DXd versus TPC, and 23.9 versus 17.6 months for the HR+ cohort, respectively (HR, 0.69 for both).
Median progression-free survival (PFS) by investigator assessment was 8.8 versus 4.2 months for the full cohort, and 9.6 versus 4.2 months for the HR+ cohort (HR, 0.36 and 0.37, respectively). PFS was consistent with the results from the primary analysis.
The benefits in the HR+ patients were consistent across all patient subgroups, Dr. Modi noted.
“I do think it’s interesting to point out that at the landmark 2-year point, all patients on standard chemotherapy discontinued study treatment, whereas 15% on T-DXd remain [on treatment] without any evidence of disease progression, Dr. Modi added
An exploratory analysis in the hormone receptor–negative (HR–) cohort showed mOS of 18.2 versus 8.3 months at the primary analysis (HR, 0.48), and a “clinically meaningful and numerical advantage for T-DXd” persisted at the planned follow-up (mOS, 17.1 vs. 8.3; HR, 0.58), she said.
PFS in the HR- cohort was 8.5 versus 2.9 months at the primary analysis, and 6.3 versus 2.9 months at the update (HR, 0.46 and 0.29, respectively).
An assessment of post-study therapies received by patients showed that those therapies did not account for the significant survival advantage conferred by T-DXd, Dr. Modi said.
She noted, however, that while no new safety signals were observed at follow-up, lung toxicity remains a “toxicity of special interest,” having occurred in 12.1% of cases at the time of the primary analysis.
Most cases were grade 1 or 2, and no new cases were observed at follow-up, but one patient with lung toxicity and an initial grade 3 event experienced clinical deterioration and later died from lung toxicity, which underscores the importance of remaining vigilant and intervening promptly in all cases of lung toxicity, Dr. Modi stressed.
Invited discussant Giampaolo Bianchini, MD, reiterated that T-DXd is an effective treatment option and said, “we must accurately identify patients and avoid improperly denying this important therapeutic option.”
Although HER2-low disease is not a unique biological disease entity, it is a “practical and pragmatic definition used to select patients with ‘some degree’ of HER2 protein expression adopting a test and a scoring system already implemented in the routine clinical practice,” said Dr. Bianchini, head of the breast cancer group and head of clinical translational and immunotherapy research at IRCCS Ospedale, San Raffaele, Milan.
However, the current definition may be inadequate, he said, explaining that the ongoing DESTINY-Breast06 study “will challenge the current definition of what we consider HER2-low definition,” potentially extending the T-DXd indication to HER2 ultra-low.
Furthermore, current HER2 testing was designed to discriminate cases with high abundant protein – not for the low HER2 dynamic range, which leads to technical inaccuracy.
Given these considerations, he suggested considering a new biopsy, if feasible, in patients with an immunohistochemistry (IHC) score of 0 in all tumor biopsies, and having a revision performed by the pathologist.
In patients with an IHC score of 1 or greater only in one biopsy, there is no need to confirm the HER2-low status, he said.

Median progression-free survival (PFS) by investigator assessment was 8.8 versus 4.2 months for the full cohort, and 9.6 versus 4.2 months for the HR+ cohort (HR, 0.36 and 0.37, respectively). PFS was consistent with the results from the primary analysis.
The benefits in the HR+ patients were consistent across all patient subgroups, Dr. Modi noted.
“I do think it’s interesting to point out that at the landmark 2-year point, all patients on standard chemotherapy discontinued study treatment, whereas 15% on T-DXd remain [on treatment] without any evidence of disease progression, Dr. Modi added
An exploratory analysis in the hormone receptor–negative (HR–) cohort showed mOS of 18.2 versus 8.3 months at the primary analysis (HR, 0.48), and a “clinically meaningful and numerical advantage for T-DXd” persisted at the planned follow-up (mOS, 17.1 vs. 8.3; HR, 0.58), she said.
PFS in the HR- cohort was 8.5 versus 2.9 months at the primary analysis, and 6.3 versus 2.9 months at the update (HR, 0.46 and 0.29, respectively).
An assessment of post-study therapies received by patients showed that those therapies did not account for the significant survival advantage conferred by T-DXd, Dr. Modi said.
She noted, however, that while no new safety signals were observed at follow-up, lung toxicity remains a “toxicity of special interest,” having occurred in 12.1% of cases at the time of the primary analysis.
Most cases were grade 1 or 2, and no new cases were observed at follow-up, but one patient with lung toxicity and an initial grade 3 event experienced clinical deterioration and later died from lung toxicity, which underscores the importance of remaining vigilant and intervening promptly in all cases of lung toxicity, Dr. Modi stressed.
Invited discussant Giampaolo Bianchini, MD, reiterated that T-DXd is an effective treatment option and said, “we must accurately identify patients and avoid improperly denying this important therapeutic option.”
Although HER2-low disease is not a unique biological disease entity, it is a “practical and pragmatic definition used to select patients with ‘some degree’ of HER2 protein expression adopting a test and a scoring system already implemented in the routine clinical practice,” said Dr. Bianchini, head of the breast cancer group and head of clinical translational and immunotherapy research at IRCCS Ospedale, San Raffaele, Milan.
However, the current definition may be inadequate, he said, explaining that the ongoing DESTINY-Breast06 study “will challenge the current definition of what we consider HER2-low definition,” potentially extending the T-DXd indication to HER2 ultra-low.
Furthermore, current HER2 testing was designed to discriminate cases with high abundant protein – not for the low HER2 dynamic range, which leads to technical inaccuracy.
Given these considerations, he suggested considering a new biopsy, if feasible, in patients with an immunohistochemistry (IHC) score of 0 in all tumor biopsies, and having a revision performed by the pathologist.
In patients with an IHC score of 1 or greater only in one biopsy, there is no need to confirm the HER2-low status, he said.
