Delaying surgery didn’t impact survival in early-stage cervical cancer
in the National Cancer Database.
The 5-year overall survival rate was 85.7% among women who had radical hysterectomy and lymphadenectomy within 4 weeks of diagnosis, 86.6% among those who had the same surgery 4-8 weeks after diagnosis, and 89.6% among those who had surgery 8-12 weeks after diagnosis (P = .12).
“For patients with clinical stage I cervical carcinoma undergoing radical hysterectomy, we found no evidence of a detrimental effect of waiting time (up to 12 weeks from diagnosis) on overall survival,” the study investigators reported in a poster at the Society of Gynecologic Oncology’s Virtual Annual Meeting on Women’s Cancer.
The investigators looked at the issue of surgical wait times because of surgery delays due to the COVID-19 pandemic, according to investigator Dimitrios Nasioudis, MD, of the University of Pennsylvania in Philadelphia.
“We wanted to see if there was a real impact in the survival of patients,” Dr. Nasioudis said in an interview. He added that “many times, there is a question of when to perform surgery,” especially when patients need medical optimization.
Dr. Nasioudis called the findings “reassuring” and said “waiting up to 3 or 4 months is reasonable.”
Still, the investigators plan to validate the results with more granular patient-level institutional data, he said. Given the limits of the database, there was no information on tumor relapse or cause of death and no central pathology review.
Study details
The study included 4,782 patients who underwent primary radical hysterectomy with lymphadenectomy. Patients had clinical stage I adenocarcinoma, squamous, or adenosquamous carcinoma of the cervix, with no history of another tumor or other cervical surgery.
The median time to surgery was 34 days across the study population. Patients were divided into three groups according to the timing of their surgery:
- Group 1 included 1,823 (38.1%) patients who had surgery less than 4 weeks from diagnosis.
- Group 2 included 2,207 (46.2%) patients who had surgery 4-8 weeks from diagnosis.
- Group 3 included 752 (15.7%) patients who had surgery 8-12 weeks from diagnosis.
Patients in group 1 had a higher rate of positive lymph nodes, compared with patients in groups 2 and 3 (18.4%, 15.6%, and 14.7%, respectively; P = .014). Patients in group 1 also had a higher incidence of lymphovascular space invasion (42.1%, 38.1%, and 33%; P = .007) and a higher rate of positive surgical margins (6.3%, 5.2%, and 3.9%; P = .047).
Group 1 patients “had more aggressive features,” which could explain why they had surgery within a month, Dr. Nasioudis said.
Patients in groups 3 and 2 were more likely to have government insurance, compared with patients in group 1 (35.6%, 31.6%, and 24.6%, respectively P < .001). Group 3 patients were more likely than those in groups 2 and 1 to have comorbidities (14.2%, 11.6%, and 10.5%; P = .29).
However, there were no survival differences between groups in a multivariate analysis controlling for confounders, which included tumor size, histology and extension, status of lymph nodes, receipt of radiotherapy, patient age, insurance, race, and comorbidities. Furthermore, in a stratified analysis based on tumor extent, the timing of surgery had no impact on survival.
Dr. Nasioudis said he suspects access to care was an issue for some women, and there were likely delays for medical optimization.
Access to gynecologic oncology services at the University of Pennsylvania is “pretty easy,” he said, so delays are usually related to medical optimization, but that’s not always the case in underserved areas of the United States.
There was no funding for this study, and the investigators didn’t have any disclosures.

Rucaparib extends PFS in BRCA-mutated ovarian cancer, with an exception
Investigator-assessed PFS in both an intention-to-treat (ITT) analysis and an efficacy analysis that excluded patients with BRCA reversion mutations was 7.4 months in the rucaparib arm, compared with 5.7 months in patients who received either platinum-based chemotherapy or weekly paclitaxel.
Among the 23 patients with BRCA reversion mutations, however, investigator-assessed PFS was 2.9 months with rucaparib and 5.5 months with chemotherapy.
Overall survival data were not mature at the time of data cutoff in September 2020.
“Although the numbers are very small, the results suggest that presence of a BRCA reversion mutation may predict a reduced benefit from rucaparib,” said Rebecca Kristeleit, MBChB, PhD, of Guy’s and St. Thomas’ NHS Foundation Trust in London.
She presented the findings from ARIEL4 at the Society of Gynecologic Oncology’s Virtual Annual Meeting on Women’s Cancer (Abstract 11479).
Invited discussant Ursula Matulonis, MD, of the Dana-Farber Cancer Institute in Boston, commented that the “BRCA reversion mutation data from ARIEL4 is intriguing. Strategies to overcome and better understand this type of resistance mechanism are needed.”
Study rationale and details
Rucaparib is approved as monotherapy for patients with BRCA-mutated, relapsed ovarian cancer who have received at least two prior lines of platinum-based chemotherapy. The approval was based on results of two phase 1/2 studies. ARIEL4 is a phase 3 confirmatory study, designed in consultation with both the U.S. Food and Drug Administration and the European Medicines Agency.
Women with relapsed, high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer with deleterious germline or somatic BRCA mutations were eligible for enrollment in ARIEL4. The patients had to have received at least two lines of chemotherapy, including at least one platinum-based regimen, with no prior PARP inhibitor or single-agent paclitaxel treatment.
Overall, 95% of patients had epithelial ovarian cancer, 3% had fallopian tube cancer, and 2% had primary peritoneal cancer. About 90% of cancers were serous in histology. Most patients (84%) had germline BRCA mutations, 16% had somatic mutations, and the status was unknown in the remaining patients.
Patients were randomized on a 2:1 basis to receive rucaparib at 600 mg twice daily (n = 233) or chemotherapy (n = 116), stratified by platinum sensitivity status. Patients assigned to chemotherapy whose disease was considered platinum resistant or partially platinum sensitive were assigned to weekly paclitaxel. Patients with fully platinum-sensitive disease were assigned to platinum-based single-agent or doublet chemotherapy. Treatment cycles were 28 days.
On radiologically confirmed disease progression or unacceptable toxicity, patients assigned to chemotherapy had the option to cross over to the rucaparib arm. The follow-up portion of the study began 28 days after the last treatment dose, with visits every 8 weeks thereafter.
Baseline characteristics in the ITT population were similar between arms. There were 13 patients in the rucaparib arm and 10 in the chemotherapy arm who had BRCA reversion mutations and were excluded from the efficacy population.
Efficacy and safety
Investigator-assessed PFS in the efficacy population was a median of 7.4 months with rucaparib and 5.7 months with chemotherapy, translating to a hazard ratio (HR) of 0.64 (P = .001). In the ITT population, the respective median PFS intervals were identical, although with a slightly less favorable HR of 0.67 (P = .002). In the 23 patients with BRCA reversion mutations, the median PFS was worse with rucaparib, at 2.9 months, compared with 5.5 months for chemotherapy. This translated to a HR of 2.77, although the 95% confidence interval was wide and crossed 1, likely due to the small sample size.
Among patients who had measurable disease at baseline, the overall response rate in the efficacy population was 40.3% with rucaparib and 32.3% with chemotherapy, a difference that was not statistically significant (P = .13). The overall response data were similar in the ITT population (37.9% and 30.2%, respectively).
In the efficacy population, the duration of response was significantly longer in the rucaparib arm, at a median of 9.4 months versus 7.2 months (HR, 0.59; 95% CI, 0.36-0.98). The respective median response durations were identical in the ITT population, but the HR was 0.56 (95% CI, 0.34-0.93).
In both the efficacy and ITT populations, global health status was virtually identical and unchanged from baseline in both treatment arms through cycle 7.
Treatment-emergent adverse events (TEAEs) were more frequent with rucaparib. The most common TEAEs in the rucaparib and chemotherapy arms, respectively, were anemia/decreased hemoglobin (53.9% and 31.9%), nausea (53.4% and 31.9%), asthenia/fatigue (49.6% and 44.2%), ALT/AST increase (34.5% and 11.5%), and vomiting (34.1% and 16.8%).
In all, 8.2% of patients in the rucaparib arm and 12.4% of those in the chemotherapy arm discontinued therapy due to TEAEs.
Four patients in the rucaparib arm developed myelodysplastic syndrome or acute myeloid leukemia – one during treatment and three during follow-up. There were no cases of myelodysplastic syndrome or acute myeloid leukemia in patients who received chemotherapy.
“Data from ARIEL4 fits the paradigm that single-agent activity of PARP inhibitors in BRCA-mutated, recurrent ovarian cancer may be comparable to chemotherapy, and may, at times, be superior, depending on the study population, trial design, and treatment for control patients,” Dr. Matulonis said.
The study was funded by Clovis Oncology. Dr. Kristeleit disclosed relationships with Clovis, Roche, and Tesaro. Dr. Matulonis disclosed relationships with Novartis, Merck, and Immunogen.

GVHD prophylaxis: Similar outcomes with PTCy and ATG
A newer regimen was no more effective than an older regimen when both were compared for graft versus host disease (GVHD) prophylaxis in patients who underwent reduced-intensity conditioning followed by a hematopoietic stem cell transplant (HSCT) from a 10/10 HLA-matched related or unrelated donor.
These results come from a multicenter randomized trial that compared posttransplant cyclophosphamide (PTCy) to antithymocyte globulin (ATG), which has been used for decades.
There were no significant differences between the two in either disease-free or overall survival, GVHD-free relapse-free survival (GRFS), or nonrelapse mortality, reported lead investigator Eolia Brissot, MD, of Hôpital Saint-Antoine, Sorbonne University, Paris.
Her presentation was judged ‘top abstract’ at the annual meeting of the European Society for Blood and Marrow Transplantation (EBMT), held virtually because of the pandemic.
ATG has been used for more than 30 years for GVHD prophylaxis in allogeneic HSCT. In contrast, PTCy is the new kid on the block, developed to facilitate haploidentical transplants using unmanipulated bone marrow cells to act as a method for selective allodepletion in vivo.
“PTCy [has proved] to be effective in preventing both acute and chronic GVHD,” Dr. Brissot said. “However, controversial outcome data remain when comparing PTCy and ATG according to the type of donors.”
Until now, she noted, there have been no prospective randomized data available for patients with donors (related or unrelated) that have 10 of 10 matched human leukocyte antigen (HLA) alleles. Hence, these were the patients studied in this latest trial, and in this population both regimens showed similar outcomes.
A bone marrow transplant specialist who was not involved in the study said that it’s a good first step.
“This is an important study to gain preliminary data to design a larger, subsequent phase 3 study,” said Zachariah DeFilipp, MD, of Mass General Cancer Center in Boston.
“The use of ATG as part of GVHD prophylaxis is common at many centers, especially in Europe, “ he explained. “The use of posttransplant cyclophosphamide is being expanded to more settings with transplant, beyond haploidentical transplant.
“Further investigations comparing the use of PTCy to ATG will help determine whether PTCy should be more broadly adopted as a standard-of-care GVHD prophylaxis approach, given currently available regimens,” he said in an interview.
Study details
The randomized phase 2b study (NCT02876679), conducted in centers in 11 cities in France, compared PTCy with ATG in patients with hematologic malignancies for whom a reduced-intensity allogeneic HSCT was indicated. This included patients aged 50 and older, and/or heavily pretreated patients who received an autologous HSCT or more than two prior lines of chemotherapy before allogeneic HSCT, as well as patients with poor performance status due to significant medical comorbidities.
Excluded from the trial were patients with creatinine clearance less than 30 mL/min; bilirubin or liver amino transferases more than three times the upper limit of normal; cardiac ejection fraction less than 40%; or pulmonary impairment with less than 50% lung carbon monoxide diffusing capacity.
Of 90 patients enrolled, 1 experienced a relapse before randomization, and the remaining 89 patients were assigned to either PTCy (experimental arm, 45 patients) or to ATG (control group, 44 patients).
Most patients had good performance status (Eastern Cooperative Oncology Group performance status 0 or 1). Diagnoses included acute myeloid and lymphoblastic leukemia, multiple myeloma, lymphomas, and myelodysplastic syndrome. The median age was 64 years, and the male to female ratio was about 2:1 in both groups.
All patients received “FB2” reduced-intensity conditioning with fludarabine30 mg/m2 per day for 4 days, and intravenous busulfan 130 mg/m2 per day for 2 days.
Patients in the experimental arm received cyclophosphamide 50 mg/kg per day on days 3 and 4 after transplant. Patients in the control group received ATG 2.5 mg/kg per day on days 3 and 2 prior to transplant.
All patients also received cyclosporine A, and those who had unrelated donors also received mycophenolate mofetil. In all, 39% of patients received cells from matched sibling donors, and 61% received cells from matched unrelated donors.
No significant differences seen
At 12 months of follow-up, there was no significant difference between the trial arms in the primary endpoint of GRFS, a composite of grade 3-4 acute GVHD, chronic GVHD requiring systemic treatment, relapse, or death. The rates of GRFS were 52.2% with PTCy vs. 45% with ATG.
Rates of disease-free survival were 68.5% with PTCy and 67.1% with ATG. The respective 12-month overall survival rates were 78.9% and 80.4%, respectively. The differences were not statistically significant.
The incidence of relapse at 1 year was 22.1% in the ATG group vs. 17.6% in the PTCy group. Respective nonrelapse mortality rates were 10.8% for the ATG group and 14% for the PTCy group. Neither difference was statistically significant.
There were also no significant between-group differences in the incidence at 12-month follow-up of either acute GVHD (34.9% PTCy arm vs. 24.3% ATG arm for grades II-IV combined, and 9.3% PTCy vs. 2.7% ATG for grades III or IV) or chronic GVHD (30.2% ATG vs. 26% PTCy).
The safety analysis showed no significant between-group differences in selected adverse events, including Epstein-Barr viral reactivation, cytomegalovirus reactivation, cardiac adverse events, or hemorrhagic cystitis.
The study was supported by Hospitals of Paris. Dr. Brissot and Dr. DeFilipp have disclosed no relevant financial relationships.

A newer regimen was no more effective than an older regimen when both were compared for graft versus host disease (GVHD) prophylaxis in patients who underwent reduced-intensity conditioning followed by a hematopoietic stem cell transplant (HSCT) from a 10/10 HLA-matched related or unrelated donor.
These results come from a multicenter randomized trial that compared posttransplant cyclophosphamide (PTCy) to antithymocyte globulin (ATG), which has been used for decades.
There were no significant differences between the two in either disease-free or overall survival, GVHD-free relapse-free survival (GRFS), or nonrelapse mortality, reported lead investigator Eolia Brissot, MD, of Hôpital Saint-Antoine, Sorbonne University, Paris.
Her presentation was judged ‘top abstract’ at the annual meeting of the European Society for Blood and Marrow Transplantation (EBMT), held virtually because of the pandemic.
ATG has been used for more than 30 years for GVHD prophylaxis in allogeneic HSCT. In contrast, PTCy is the new kid on the block, developed to facilitate haploidentical transplants using unmanipulated bone marrow cells to act as a method for selective allodepletion in vivo.
“PTCy [has proved] to be effective in preventing both acute and chronic GVHD,” Dr. Brissot said. “However, controversial outcome data remain when comparing PTCy and ATG according to the type of donors.”
Until now, she noted, there have been no prospective randomized data available for patients with donors (related or unrelated) that have 10 of 10 matched human leukocyte antigen (HLA) alleles. Hence, these were the patients studied in this latest trial, and in this population both regimens showed similar outcomes.
A bone marrow transplant specialist who was not involved in the study said that it’s a good first step.
“This is an important study to gain preliminary data to design a larger, subsequent phase 3 study,” said Zachariah DeFilipp, MD, of Mass General Cancer Center in Boston.
“The use of ATG as part of GVHD prophylaxis is common at many centers, especially in Europe, “ he explained. “The use of posttransplant cyclophosphamide is being expanded to more settings with transplant, beyond haploidentical transplant.
“Further investigations comparing the use of PTCy to ATG will help determine whether PTCy should be more broadly adopted as a standard-of-care GVHD prophylaxis approach, given currently available regimens,” he said in an interview.
Study details
The randomized phase 2b study (NCT02876679), conducted in centers in 11 cities in France, compared PTCy with ATG in patients with hematologic malignancies for whom a reduced-intensity allogeneic HSCT was indicated. This included patients aged 50 and older, and/or heavily pretreated patients who received an autologous HSCT or more than two prior lines of chemotherapy before allogeneic HSCT, as well as patients with poor performance status due to significant medical comorbidities.
Excluded from the trial were patients with creatinine clearance less than 30 mL/min; bilirubin or liver amino transferases more than three times the upper limit of normal; cardiac ejection fraction less than 40%; or pulmonary impairment with less than 50% lung carbon monoxide diffusing capacity.
Of 90 patients enrolled, 1 experienced a relapse before randomization, and the remaining 89 patients were assigned to either PTCy (experimental arm, 45 patients) or to ATG (control group, 44 patients).
Most patients had good performance status (Eastern Cooperative Oncology Group performance status 0 or 1). Diagnoses included acute myeloid and lymphoblastic leukemia, multiple myeloma, lymphomas, and myelodysplastic syndrome. The median age was 64 years, and the male to female ratio was about 2:1 in both groups.
All patients received “FB2” reduced-intensity conditioning with fludarabine30 mg/m2 per day for 4 days, and intravenous busulfan 130 mg/m2 per day for 2 days.

Can supplementary estrogen relieve MS symptoms in menopausal women?
, a neurologist told colleagues at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
This kind of research should explore the effects of aging, including in the brain, and “focus on what is preventable – this dramatic and abrupt loss of estrogen in women with MS,” said Rhonda Voskuhl, MD, of the Brain Research Institute at the University of California, Los Angeles.
“This is a call to action. There’s a huge gap that needs to be filled,” she added in an interview. “Not enough attention has been paid to menopause and cognitive issues in MS and even in healthy women.”
Research has found that many women with MS experience a decline in function during menopause, she said. “They’re having a worsening of their preexisting disabilities,” she noted, due to neurodegeneration.
Dr. Voskuhl highlighted a 2016 study, for instance, that found postmenopausal women with MS on hormone replacement therapy reported better physical function and quality of life than did their counterparts after adjustment for covariates. She also pointed to a 2019 study that concluded that “natural menopause seems to be a turning point to a more progressive phase of MS.”
Estrogen appears to play a significant role. “It’s involved in synaptic plasticity,” she said. “That’s why the disabilities are worsening.”
Dr. Voskuhl supports a year-long, randomized and controlled study of estrogen supplementation in 150-200 participants. The goal, she said, is “not just to prevent loss and bad things from happening but also make improvements.”
In healthy patients, she said, outcomes should include cognitive decline in menopause, cognitive domain outcomes, and region-specific biomarkers in the frontal cortex and hippocampus instead of global cognition and global brain volume. In patients with MS, she said, the focus should be on worsening of disability with emphasis on specific disabilities such as walking and region-specific biomarkers for the motor cortex and spinal cord.
“We need to be looking at cortical gray matter, which we know is responsive to estrogen,” Dr. Voskuhl said. She led a 2018 placebo-controlled study that found women with MS who took estrogen supplements appeared to experience localized sparing of progressive gray matter, which the researchers linked to improved results in cognitive testing. The findings, the study authors wrote, suggest “a clinically relevant, disability-specific biomarker for clinical trials of candidate neuroprotective treatments in MS.”
What about men? Does hormone loss worsen their MS? Dr. Voskuhl said there seems to be a connection between lower levels of testosterone and more disability in men with MS. But their situation is different. Loss of testosterone in men is gradual and happens over decades instead of over the short period of menopause in women, she said.
Jennifer Graves, MD, a neurologist at the University of California, San Diego, agreed that it’s time for further research into estrogen supplementation in MS. As she noted, “we don’t know the exact biological mechanism that might link perimenopause with developing a more progressive type of MS.”
She added: “An overall decrease in estrogen may be at play but there are other biological changes around menopause. We must also take care in studies to try to separate out what might be due to ovarian aging versus other types of aging processes that might be happening at the same time.”
Dr. Voskuhl disclosed that she is an inventor on university patents for use of estriol and estrogen receptor–beta ligands as treatments. Dr. Graves reports no relevant disclosures.

FROM ACTRIMS FORUM 2021
Colchicine before PCI for acute MI fails to improve major outcomes
In a placebo-controlled randomized trial, a preprocedural dose of colchicine administered immediately before percutaneous coronary intervention (PCI) for an acute ST-segment elevated myocardial infarction (STEMI) did not reduce the no-reflow phenomenon or improve outcomes.
No-reflow, in which insufficient myocardial perfusion is present even though the coronary artery appears patent, was the primary outcome, and the proportion of patients experiencing this event was exactly the same (14.4%) in the colchicine and placebo groups, reported Yaser Jenab, MD, at CRT 2021 sponsored by MedStar Heart & Vascular Institute.
The hypothesis that colchicine would offer benefit in this setting was largely based on the Colchicine Cardiovascular Outcomes Trial (COLCOT). In that study, colchicine was associated with a 23% reduction in risk for major adverse cardiovascular events (MACE) relative to placebo when administered within 30 days after a myocardial infarction (hazard ratio, 0.77; P = .02).
The benefit in that trial was attributed to an anti-inflammatory effect, according to Dr. Jenab, associate professor of cardiology at Tehran (Iran) Heart Center. In particular as it relates to vascular disease, he cited experimental studies associating colchicine with a reduction in neutrophil activation and adherence to vascular endothelium.
The rationale for a preprocedural approach to colchicine was supplied by a subsequent time-to-treatment COLCOT analysis. In this study, MACE risk reduction for colchicine climbed to 48% (HR 0.52) for those treated within 3 days of the MI but largely disappeared (HR 0.96) if treatment was started at least 8 days post MI.
PodCAST-PCI trial
In the preprocedural study, called the PodCAST-PCI trial, 321 acute STEMI patients were randomized. Patients received a 1-mg dose of oral colchicine or placebo at the time PCI was scheduled. Another dose of colchicine (0.5 mg) or placebo was administered 1 hour after the procedure.
Of secondary outcomes, which included MACE at 1 month and 1 year, ST-segment resolution at 1 month, and change in inflammatory markers at 1 month, none were significant. Few even trended for significance.
For MACE, which included cardiac death, stroke, nonfatal MI, new hospitalization due to heart failure, or target vessel revascularization, the rates were lower in the colchicine group at 1 month (4.3% vs. 7.5%) and 1 year (9.3% vs. 11.2%), but neither approached significance.
For ST-segment resolution, the proportions were generally comparable among the colchicine and placebo groups, respectively, for the proportion below 50% (18.6% vs. 23.1%), between 50% and 70% (16.8% vs. 15.6%), and above 70% (64.6% vs. 61.3%).
The average troponin levels were nonsignificantly lower at 6 hours (1,847 vs. 2,883 ng/mL) in the colchicine group but higher at 48 hours (1,197 vs. 1,147 ng/mL). The average C-reactive protein (CRP) levels at 48 hours were nonsignificantly lower on colchicine (176.5 vs. 244.5 mg/L).
There were no significant differences in postprocedural perfusion, as measured with TIMI blood flow, or in the rate of stent thrombosis, which occurred in roughly 3% of each group of patients.
The small sample size was one limitation of this study, Dr. Jenab acknowledged. For this and other reasons, he cautioned that these data are not definitive and do not preclude a benefit on clinical outcomes in a study with a larger size, a different design, or different dosing.
Timing might be the issue
However, even if colchicine has a potential benefit in this setting, timing might be a major obstacle, according to Binata Shah, MD, associate director of research for the Cardiac Catheterization Laboratory at New York University.
“We have learned from our rheumatology colleagues that peak plasma levels of colchicine are not achieved for at least 1 hour after the full loading dose,” Dr. Shah said. “With us moving so quickly in a primary PCI setting, it is hard to imagine that colchicine would have had time to really kick in and exert its anti-inflammatory effect.”
Indeed, the problem might be worse than reaching the peak plasma level.
“Even though peak plasma levels occur as early as 1 hour after a full loading dose, we see that it takes about 24 hours to really see the effects translate downstream into more systemic inflammatory markers such as CRP and interleukin-6,” she added. If lowering these signals of inflammation is predictive of benefit, than this might be the biggest obstacle to benefit from colchicine in an urgent treatment setting.
Dr. Jenab and Dr. Shah reported no potential conflicts of interest.

In that study, colchicine was associated with a 23% reduction in risk for major adverse cardiovascular events (MACE) relative to placebo when administered within 30 days after a myocardial infarction (hazard ratio, 0.77; P = .02).
The benefit in that trial was attributed to an anti-inflammatory effect, according to Dr. Jenab, associate professor of cardiology at Tehran (Iran) Heart Center. In particular as it relates to vascular disease, he cited experimental studies associating colchicine with a reduction in neutrophil activation and adherence to vascular endothelium.
The rationale for a preprocedural approach to colchicine was supplied by a subsequent time-to-treatment COLCOT analysis. In this study, MACE risk reduction for colchicine climbed to 48% (HR 0.52) for those treated within 3 days of the MI but largely disappeared (HR 0.96) if treatment was started at least 8 days post MI.
PodCAST-PCI trial
In the preprocedural study, called the PodCAST-PCI trial, 321 acute STEMI patients were randomized. Patients received a 1-mg dose of oral colchicine or placebo at the time PCI was scheduled. Another dose of colchicine (0.5 mg) or placebo was administered 1 hour after the procedure.
Of secondary outcomes, which included MACE at 1 month and 1 year, ST-segment resolution at 1 month, and change in inflammatory markers at 1 month, none were significant. Few even trended for significance.
For MACE, which included cardiac death, stroke, nonfatal MI, new hospitalization due to heart failure, or target vessel revascularization, the rates were lower in the colchicine group at 1 month (4.3% vs. 7.5%) and 1 year (9.3% vs. 11.2%), but neither approached significance.
For ST-segment resolution, the proportions were generally comparable among the colchicine and placebo groups, respectively, for the proportion below 50% (18.6% vs. 23.1%), between 50% and 70% (16.8% vs. 15.6%), and above 70% (64.6% vs. 61.3%).
The average troponin levels were nonsignificantly lower at 6 hours (1,847 vs. 2,883 ng/mL) in the colchicine group but higher at 48 hours (1,197 vs. 1,147 ng/mL). The average C-reactive protein (CRP) levels at 48 hours were nonsignificantly lower on colchicine (176.5 vs. 244.5 mg/L).
There were no significant differences in postprocedural perfusion, as measured with TIMI blood flow, or in the rate of stent thrombosis, which occurred in roughly 3% of each group of patients.
The small sample size was one limitation of this study, Dr. Jenab acknowledged. For this and other reasons, he cautioned that these data are not definitive and do not preclude a benefit on clinical outcomes in a study with a larger size, a different design, or different dosing.
Timing might be the issue
However, even if colchicine has a potential benefit in this setting, timing might be a major obstacle, according to Binata Shah, MD, associate director of research for the Cardiac Catheterization Laboratory at New York University.
“We have learned from our rheumatology colleagues that peak plasma levels of colchicine are not achieved for at least 1 hour after the full loading dose,” Dr. Shah said. “With us moving so quickly in a primary PCI setting, it is hard to imagine that colchicine would have had time to really kick in and exert its anti-inflammatory effect.”
Indeed, the problem might be worse than reaching the peak plasma level.
“Even though peak plasma levels occur as early as 1 hour after a full loading dose, we see that it takes about 24 hours to really see the effects translate downstream into more systemic inflammatory markers such as CRP and interleukin-6,” she added. If lowering these signals of inflammation is predictive of benefit, than this might be the biggest obstacle to benefit from colchicine in an urgent treatment setting.
Dr. Jenab and Dr. Shah reported no potential conflicts of interest.

Telerheumatology will thrive post pandemic
Telemedicine has had a profound effect upon the practice of rheumatology during the COVID-19 pandemic and will continue to do so afterward, speakers predicted at the 2021 Rheumatology Winter Clinical Symposium.
“Telemedicine will change the way we do business. It already has,” observed Eric M. Ruderman, MD, professor of medicine (rheumatology) at Northwestern University in Chicago.
“All of a sudden in March of last year we all turned on a dime and went 100% remote, and we made it work. And it has worked well. It’s not the same as seeing people in person, but I’m pretty sure that going forward probably somewhere in the range of 30% of our visits are going to be telemedicine. It’s an incredible way to deal with people who are stable and are driving in from an hour-and-a-half away to get their prescription refilled,” he said.
Conditions well suited for video patient visits are those where the physical exam isn’t informative or necessary, such as polymyalgia rheumatica, axial spondyloarthritis with axial disease only, childhood periodic fever syndromes, and even many cases of rheumatoid arthritis, in Dr. Ruderman’s view.
“People who are stable – maybe not in remission, but we’ve decided they’re at that their target – a lot of those visits can be done remotely. It’s way more efficient. Everybody loves it: We like it, the patients like it. But we have to get to where we can do it better. The technology is clumsy right now,” he said.
“We do need better and smarter platforms,” agreed Alvin F. Wells, MD, PhD, a telerheumatology pioneer who has been involved in digital/video communication with his patients for nearly 6 years. “But the biggest issue is connectivity. Not all of our patients can get on the Internet.”
The telerheumatology paradigm he has used during the pandemic and will continue to use afterward is to see every new patient in the office, then do the follow-up visits virtually.
“They don’t need to come back into the office in 4 weeks. I’ve done my physical exam, ordered the x-rays and lab work. At the virtual 4-week follow-up we go over everything and I tell them if they need to come in for training in giving their injections,” explained Dr. Wells, a rheumatologist in Franklin, Wisc.
“The telemedicine visit doesn’t take the place of an in-person visit, but it allows you to stratify, to say who needs to be seen sooner rather than later,” he added.
While he anticipates that physician-patient virtual visits will continue to be an important part of clinical practice post pandemic, he predicted the major growth areas for telerheumatology once COVID-19 is squashed will be in clinician-to-clinician interactions and remote patient monitoring using smart devices.
Dr. Wells hasn’t gone into the hospital once since the pandemic began. Initially, that was because he didn’t want to deal with the personal protective equipment shortage or expose himself to the virus. Now, it’s because it’s just a more efficient use of his time to conduct virtual – and billable – 15-minute e-consults with clinicians in the hospital.
“I’ve had a lot of appropriate consults with the hospitalists,” he said. He can walk a hospitalist through a real-time physical exam at a gout patient’s bedside and order the right laboratory tests.
“I don’t need to go into the hospital. The interventional radiologist can tap an ankle or toe as well as I can,” the rheumatologist said.
Dermatologist George Martin, MD, rose from the audience to say that while he recognizes that pandemic telemedicine has been a good fit for rheumatologists, it’s been a very different story in dermatology.
“I realize telemedicine works really well when you don’t have to lay your hands on a patient, or when you’re just doing a stable follow-up and talking about test results. But we in dermatology have found as a group that telemedicine is pretty worthless. When patients are trying to send you a video stream of what their melanoma looks like, or maybe it’s a benign seborrheic keratosis, you’re going to hang their life on that? Dermatology is a very hands-on, visual thing, and unless the camera work becomes better telemedicine is worthless, with the exception of a laboratory follow-up or a stable visit where a physical exam is not required,” declared Dr. Martin, who is in private practice in Maui.
Dr. Wells reported serving as a consultant to MiCare Path, a remote health and monitoring company.

Novel Alzheimer’s drug slows cognitive decline in phase 2 trial
Results from the TRAILBLAZER-ALZ trial were presented at the 2021 International Conference on Alzheimer’s and Parkinson’s Diseases (AD/PD) and were simultaneously published online March 13 in the New England Journal of Medicine.
As previously reported by Medscape Medical News, topline results showed that donanemab slowed cognitive decline by 32% on the Integrated AD Rating Scale (iADRS) from baseline to 76 weeks relative to placebo.
The newly released detailed findings showed that “the use of donanemab resulted in a better composite score for cognition and for the ability to perform activities of daily living than placebo at 76 weeks, although results for secondary outcomes were mixed,” the investigators, with first author Mark A. Mintun, MD, an employee of Eli Lilly, reported.
Results revealed improvement in scores on the Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) and the 13-item cognitive subscale of the AD Assessment Scale (ADAS-Cog13), but the differences between the two treatment groups were not significant. In addition, score changes on the AD Cooperative Study–Instrumental Activities of Daily Inventory (ADCS-iADL) and the Mini-Mental State Examination (MMSE) were not “substantial.”
However, the donanemab group did show an 85-centiloid greater reduction in amyloid plaque level at 76 weeks, as shown on PET, compared with the placebo group.
Proof of concept?
The humanized antibody donanemab, which was previously known as LY3002813, targets a modified form of deposited amyloid-beta (A-beta) peptide called N3pG.
The randomized, placebo-controlled, double-blind TRAILBLAZER-ALZ trial, which was described as a “phase 2 proof of concept trial” in the AD/PD program, was conducted at 56 sites in the United States and Canada and included 257 patients between the ages of 60 and 85 years (52% were women). PET confirmed tau and amyloid deposition in all participants.
The active treatment group (n = 131) was randomly assigned to receive donanemab 700 mg for three doses; after that, treatment was bumped up to 1,400 mg. Both the donanemab and placebo groups (n = 126) received treatment intravenously every 4 weeks for up to 72 weeks.
Participants also underwent F-florbetapir and F-flortaucipir PET scans at various timepoints and completed a slew of cognitive tests.
The study’s primary outcome measure was change between baseline and 76 weeks post treatment on composite score for cognition, as measured by the iADRS. The iADRS combines the ADAS-Cog13 and the ADCS-iADL.
This measure ranges from 0 to 144, with lower scores associated with greater cognitive impairment. Both treatment groups had an iADRS score of 106 at baseline.
More research needed
Results showed that the score change from baseline on the iADRS was –6.86 for the active treatment group vs –10.06 for the placebo group (group difference, 3.2; 95% confidence interval [CI], 0.12-6.27; P = .04). Although significant, “the trial was powered to show a 6-point difference,” which was not met, the investigators note.
Differences in score changes from baseline to 76 weeks for the treatment vs. placebo groups on the following secondary outcome measures were:
- CDR-SB: –0.36 (95% CI, –0.83 to –0.12).
- ADAS-Cog13: –1.86 (95% CI, –3.63 to –0.09).
- ADCS-iADL: 1.21 (95% CI, –0.77 to 3.2).
- MMSE: 0.64 (95% CI, –0.4 to 1.67).
The CDR-SB was designated as the first secondary outcome, and because it did not show a significant between-group difference, “the hierarchy failed and no definite conclusions can be drawn from data regarding the differences between groups in the change in the ADAS-Cog13,” the investigators wrote.
In addition, the differences in scores on the latter two secondary outcomes were not “substantial,” they reported.
However, at 76 weeks, the donanemab group showed a reduction of 84.13 centiloids in amyloid plaque level vs. an increase of 0.93 centiloids in the placebo group (between-group difference, 85.06 centiloids). At 24 weeks, the active-treatment group had a 67.83-centiloids greater reduction vs. the placebo group.
In addition, 40%, 59.8%, and 67.8% of the donanemab group achieved “amyloid-negative status” at 24, 52, and 76 weeks, respectively. Amyloid-negative status was defined as an amyloid plaque level of less than 24.1 centiloids.
Total incidence of death or serious adverse events did not differ significantly between the groups. However, the donanemab group had significantly more reports of ARIA-E compared with the placebo group (26.7% vs. 0.8%).
Overall, the researchers noted that more trials of longer duration with larger patient numbers are warranted “to further determine the efficacy and safety of donanemab” in AD.
Positive signal?
In a statement, Maria Carrillo, PhD, chief science officer for the Alzheimer’s Association, said the organization “is encouraged by this promising data.
“It is the first phase 2 Alzheimer’s trial to show positive results on a primary outcome measure related to memory and thinking,” Dr. Carrillo said. However, “more work needs to be done on this experimental drug therapy.”
Dr. Carrillo noted that because the trial was moderately sized and only 180 participants completed the study, “we look forward to the results of a second, larger phase 2 trial of this drug.”
Still, she added, there were several “novel and innovative aspects” in the way the study was conducted noting that it showcases the evolution of AD research.
“I’m hopeful for the future,” Dr. Carrillo said.
Also commenting on the results, Howard Fillit, MD, neuroscientist and founding executive director and chief science officer of the Alzheimer’s Drug Discovery Foundation, said the study showed “the pharmacology works” and that the drug did what it was supposed to do in terms of removing A-beta plaque.
“It also gave us a signal in a relatively small phase 2 study that there might be a modest cognitive benefit,” said Dr. Fillit, who was not involved with the research.
He noted that although the rate of decline slowing was statistically significant it remains to be seen whether this is clinically meaningful, particularly in light of the fact that the secondary outcome results were mixed.
“Basically, it was a positive study that probably needs to be followed by another, much larger study to get us to really see the benefit,” Dr. Fillit said.
Dr. Mintun is an employee of Eli Lilly, which funded the study. Dr. Carrillo and Dr. Fillit have reported no relevant financial relationships.

The study’s primary outcome measure was change between baseline and 76 weeks post treatment on composite score for cognition, as measured by the iADRS. The iADRS combines the ADAS-Cog13 and the ADCS-iADL.
This measure ranges from 0 to 144, with lower scores associated with greater cognitive impairment. Both treatment groups had an iADRS score of 106 at baseline.
More research needed
Results showed that the score change from baseline on the iADRS was –6.86 for the active treatment group vs –10.06 for the placebo group (group difference, 3.2; 95% confidence interval [CI], 0.12-6.27; P = .04). Although significant, “the trial was powered to show a 6-point difference,” which was not met, the investigators note.
Differences in score changes from baseline to 76 weeks for the treatment vs. placebo groups on the following secondary outcome measures were:
- CDR-SB: –0.36 (95% CI, –0.83 to –0.12).
- ADAS-Cog13: –1.86 (95% CI, –3.63 to –0.09).
- ADCS-iADL: 1.21 (95% CI, –0.77 to 3.2).
- MMSE: 0.64 (95% CI, –0.4 to 1.67).
The CDR-SB was designated as the first secondary outcome, and because it did not show a significant between-group difference, “the hierarchy failed and no definite conclusions can be drawn from data regarding the differences between groups in the change in the ADAS-Cog13,” the investigators wrote.
In addition, the differences in scores on the latter two secondary outcomes were not “substantial,” they reported.
However, at 76 weeks, the donanemab group showed a reduction of 84.13 centiloids in amyloid plaque level vs. an increase of 0.93 centiloids in the placebo group (between-group difference, 85.06 centiloids). At 24 weeks, the active-treatment group had a 67.83-centiloids greater reduction vs. the placebo group.
In addition, 40%, 59.8%, and 67.8% of the donanemab group achieved “amyloid-negative status” at 24, 52, and 76 weeks, respectively. Amyloid-negative status was defined as an amyloid plaque level of less than 24.1 centiloids.
Total incidence of death or serious adverse events did not differ significantly between the groups. However, the donanemab group had significantly more reports of ARIA-E compared with the placebo group (26.7% vs. 0.8%).
Overall, the researchers noted that more trials of longer duration with larger patient numbers are warranted “to further determine the efficacy and safety of donanemab” in AD.
Positive signal?
In a statement, Maria Carrillo, PhD, chief science officer for the Alzheimer’s Association, said the organization “is encouraged by this promising data.
“It is the first phase 2 Alzheimer’s trial to show positive results on a primary outcome measure related to memory and thinking,” Dr. Carrillo said. However, “more work needs to be done on this experimental drug therapy.”
Dr. Carrillo noted that because the trial was moderately sized and only 180 participants completed the study, “we look forward to the results of a second, larger phase 2 trial of this drug.”
Still, she added, there were several “novel and innovative aspects” in the way the study was conducted noting that it showcases the evolution of AD research.
“I’m hopeful for the future,” Dr. Carrillo said.
Also commenting on the results, Howard Fillit, MD, neuroscientist and founding executive director and chief science officer of the Alzheimer’s Drug Discovery Foundation, said the study showed “the pharmacology works” and that the drug did what it was supposed to do in terms of removing A-beta plaque.
“It also gave us a signal in a relatively small phase 2 study that there might be a modest cognitive benefit,” said Dr. Fillit, who was not involved with the research.
He noted that although the rate of decline slowing was statistically significant it remains to be seen whether this is clinically meaningful, particularly in light of the fact that the secondary outcome results were mixed.
“Basically, it was a positive study that probably needs to be followed by another, much larger study to get us to really see the benefit,” Dr. Fillit said.
Dr. Mintun is an employee of Eli Lilly, which funded the study. Dr. Carrillo and Dr. Fillit have reported no relevant financial relationships.

RA expert updates latest pathologic findings from Accelerating Medicines Partnership
Macrophages are among the most important inflammatory cells in the synovium of patients with rheumatoid arthritis, according to research discussed at the Canadian Arthritis Research Conference: Research with Impact.
Work conducted as part of the Accelerating Medicines Partnership (AMP) Rheumatoid Arthritis and Systemic Lupus Erythematosus (RA/SLE) Network suggests that not only do macrophages play an inflammatory role, but there may also be a subset of macrophages that have a predominantly anti-inflammatory effect.
“These are cells that are really activated and can produce a lot of proinflammatory cytokines, including TNF [tumor necrosis factor],” said Jennifer Howitt Anolik, MD, PhD, associate professor of medicine at the University of Rochester (N.Y.) and cochair of the AMP RA/SLE Network.
“In addition to inflammatory mediators there’s an anti-inflammatory population which may control the disease,” she added, at the virtual meeting, which was sponsored by The Arthritis Society, the Canadian Rheumatology Association, and Canada’s Institute of Health and Arthritis.
There are up to 15 different populations of macrophages found so far as part of a project by Fan Zhang of Brigham and Women’s Hospital and Harvard Medical School in Boston, Dr. Anolik revealed. Of these, three have been shown to be proinflammatory and five have been shown to be anti-inflammatory – including one of particular interest that expresses MERTK, which recent work suggests are lacking in people with RA, compared with a control population of people with osteoarthritis (OA).
Clearly, Dr. Anolik said, there is “lots more work to do to understand how those anti-inflammatory monocytes might work, understand the relationship to treatment response and treatment failure, and how to target them.”
AMP RA/SLE Network: Examining RA synovial tissue
What’s unique about the AMP’s work is that it is involving single-cell analytics in which individual cells derived from patients with RA are subjected to an array of RNA sequencing and molecular classification methods.
“If we’re able to define the cells that are driving the disease at the tissue level, this may lead to better therapeutics and more of like a precision medicine approach,” Dr. Anolik said. An important feature of the AMP’s work is that it is based on the use of existing and thus “very informative cohorts” for whom we know a lot about disease characteristics, she said.
The AMP RA/SLE Network officially formed in 2014 and is a public–private partnership between the National Institutes of Health, the Food and Drug Administration, several biopharmaceutical companies, and nonprofit organizations. The task was to try to accelerate discoveries that would lead to better patient care.
“The initial phase [Research Phase 0], was really about developing the procedures in a standardized way,” Dr. Anolik said. “Because we’re looking at patient joint tissue samples, we needed to access that tissue and that required developing needle biopsy approaches.” Synovial biopsy had been pioneered in the United Kingdom and become fairly standard to perform, she added, but this was not an approach that was routinely being used in the United States at the time.
In the next step, Research Phase I, researchers looked at the expression profiles of RA synovial cells in a small group of patients. In all, around 5,000 cells from the joints of up to 20 patients with RA were analyzed. What was apparent was that while there were fibroblasts, monocytes, T cells, and B cells all present to some degree, there was substantial heterogeneity among those subtypes.
“Within all the different immune cells and stromal cells, we found 18 different populations overall,” Dr. Anolik said, giving some of the top-level findings. Both single-cell RNA sequencing and mass cytometry revealed that there were greatly (16-fold) increased numbers of a population of sublining fibroblasts and a 3.3-fold increase in interleukin-1-beta-expressing proinflammatory monocytes. There was a threefold increase in a subset of B cells expressing CD11/T-bet, and a 2.4-fold increase in certain peripheral T cells.
“Interestingly, we were able to pinpoint which cells are making which kinds of inflammatory mediators like inflammatory cytokines,” Dr. Anolik said. Notably, one of the fibroblast populations and one of the B cells were prominent producers of interleukin-6.
The AMP RA/SLE Network is now in Research Phase II, looking at much greater numbers of cells (>5,000) in more than 100 samples from individual patients. It’s a “very comprehensive, big data look at RA,” according to Dr. Anolik.
Research Phase II will also see more rigorous groups of patients being examined, including those who have not had any or much exposure to disease-modifying antirheumatic drugs and those who have inadequately responded to methotrexate or anti-TNF drugs.
Recent AMP RA/SLE Network findings
Recent work by the AMP RA/SLE Network has shown that stromal fibroblasts can become highly inflammatory in RA.
“What’s becoming clear is that these are more than just lining of the joint or structure of the joint, they actually play an active role in the disease,” Dr. Anolik said.
There is a lot of diversity in these fibroblasts but they broadly fall into lining or sublining subtypes. Those that are proinflammatory tend to express markers such as HLA-DR and CD90, and one that is of notable interest is a subgroup of sublining fibroblasts that express Notch3. Indeed, it has been shown that the higher the number of Notch3-expressing fibroblasts there are in the joint, the greater the level of inflammation. Also, mice lacking Notch3 seem to get less arthritis than those with Notch3. This makes Notch3 an interesting potential target that no one had thought of before.
Dr. Anolik noted that some evolving concepts about T cells include evidence showing CD8-postive T cells are more abundant in the joint tissue than previously thought and, together with natural killer (NK) cells, are an important producer of interferon-gamma.
“There are some very interesting CD4 T-cell populations, including an expansion of T peripheral helper cells that may be very important in driving B-cell activation,” Dr. Anolik said. There are also many other clusters of T cells and NK cells that have unknown roles.
Over the past years, Dr. Anolik’s research had focused on the role B cells play in autoimmune disease, and one of the cells of interest are known as age-related B cells, or ABCs. High percentages of ABCs have been found in the RA synovium, and these seem to be related to disease activity as measured by the Disease Activity Score in 28 joints (DAS28). These cells also seem to cluster with some of the T helper cell populations found in the joint. Another interesting target could be B cells expressing a transcription factor known as T-bet. Work in mice suggests that the absence of T-bet B cells could be associated with reduced levels of arthritis.
“One of the things that we’re really interested in about B cells, in addition to their production of autoantibodies, is that they may be important for some of the structural damage that occurs with rheumatoid arthritis,” she said.
T-bet B cells seem to have an effect on both osteoclasts and osteoblasts – activating one while inhibiting the other to have a negative effect on bone overall, she explained. However, knocking out T-bet seems to resolve this, again suggesting that T-bet B cells may be another interesting subpopulation to target.
“Overall, the AMP has been a really interesting approach. This is a massive data set. We are putting the data together now to publish, and it will be available in the public domain,” Dr. Anolik said.
Members of the AMP RA/SLE Network include: AbbVie, the Arthritis Foundation, Bristol‐Myers Squibb, the Foundation for the NIH, the Lupus Foundation of America, the Lupus Research Alliance, Merck Sharp & Dohme, the National Institute of Allergy and Infectious Diseases, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, Pfizer, the Rheumatology Research Foundation, Sanofi, and Takeda Pharmaceuticals International.

FROM CARC 2021
Target-lesion failure reduced 2 years after MI with biodegradable stent
For a primary composite target-lesion failure outcome, a biodegradable polymer sirolimus-eluting stent showed superiority at 2 years over a durable polymer everolimus-eluting stent in patients undergoing percutaneous intervention (PCI) for an ST-segment elevated acute myocardial infarction (STEMI), according to a late-breaking trial presentation at CRT 2021.
As in the previously reported 1-year results from the BIOSTEMI trial, the advantage of the biodegradable device was “driven by lower rates of target-lesion revascularization,” reported Thomas Pilgrim, MD, of the University of Bern (Switzerland).
Drug-eluting stents have already been established as superior to bare-metal stents, but the question asked in this study is whether the polymer that carries antiproliferative drugs, such as sirolimus or everolimus, improves lesion-based outcomes if it is biodegradable rather than durable, Dr. Pilgrim explained.
The composite primary outcome was target-lesion failure defined by cardiac death, target-lesion MI, or clinically indicated target-lesion revascularization.
After 2 years of follow-up, the rates of target-lesion failure were 5.1% and 8.1% for the biodegradable and durable polymer stents, respectively. This 0.58 rate ratio was statistically significant, favoring the biodegradable stent.
The investigator-initiated BIOSTEMI trial randomized 1,300 patients to one of two drug-eluting stents with ultrathin struts. One was the Orsiro stent that employs a biodegradable polymer to deliver sirolimus. The other was the Xience Prime/Xpedition that uses a durable polymer stent to deliver everolimus.
The strut thicknesses of the Orsiro stent are 60 mcm for stents of 3.0 mm in diameter or smaller and 80 mcm for those with a larger diameter. The strut thickness of the Xience stent is 81 mcm regardless of diameter.
“Patients with an acute myocardial infarction are at increased risk of stent-related events due to exacerbated inflammatory response and delayed arterial healing,” Dr. Pilgrim said. The theoretical advantages of polymer that biodegrades include “mitigation of the arterial injury, facilitation of endothelialization, and reduced intimal hyperplasia,” he explained at the meeting sponsored by MedStar Heart & Vascular Institute.
The rates of cardiac death (2.9% vs. 3.2%) and target-vessel MI (2.9% vs. 3.2%) were lower for the biodegradable polymer stent, but not significantly. However, the rates of target-vessel revascularization at 2 years were 2.5% versus 5.1%. The associated rate ratio of 0.52 favoring the biodegradable stent was significant.
Similar results favoring the biodegradable polymer stent were observed at 1 year, but those earlier results factored in historical data from the BIOSCIENCE trial, using a Bayesian analysis, to improve the power of the comparison. In this 2-year analysis, the superiority of the biodegradable polymer stent to the durable polymer stent remained statistically significant even when excluding those historical controls.
The advantage of the biodegradable polymer stent was confined to “device-oriented” outcomes, according to Dr. Pilgrim. When compared for important patient-oriented outcomes at 2 years, there were no significant differences. Rather, several were numerically more common, including death (4.2% vs. 3.8%) and MI (3.7% vs. 3.1%) in those who were randomized to the biodegradable polymer stent.
But these types of clinical outcomes are not necessarily related to stent assignment because “up to one-half of all events over the 2 years of follow-up were unrelated to the stent implanted,” Dr. Pilgrim said. He noted that high rates of events unrelated to the implanted stent have also been seen in follow-up of other comparative stent trials.
The superiority of the biodegradable stent is noteworthy. Although Dr. Pilgrim described the BIOSTEMI trial as “the first head-to-head comparison of two new-generation drug-eluting stents in patients undergoing a primary percutaneous intervention for acute myocardial infarction,” there have been several studies comparing stents for other indications. Significant differences have been uncommon.
“Over the last 10 years, we have seen a number of noninferiority stent trials, but only now are we seeing some superiority differences. This is a move in the right direction,” commented Sripal Bangalore, MD, director of the cardiovascular outcomes group, New York University.
However, he, like others, questioned whether the difference in outcomes in this trial could be fully attributed to the type of polymer. He noted that all stents could be characterized by multiple small and large differences in design and composition. Any specific characteristic, such as biodegradable polymer, might be an important contributor but not an isolated factor in the outcomes observed.
On the day that the 2-year results of the BIOSTEMI trial were presented at the CRT 2021 meeting they were simultaneously published in JACC: Cardiovascular Interventions.
Dr. Pilgrim reports financial relationships with several companies that make stent devices, including Biotronik and Boston Scientific. Dr. Bangalore reports no potential conflicts of interest.

The theoretical advantages of polymer that biodegrades include “mitigation of the arterial injury, facilitation of endothelialization, and reduced intimal hyperplasia,” he explained at the meeting sponsored by MedStar Heart & Vascular Institute.
The rates of cardiac death (2.9% vs. 3.2%) and target-vessel MI (2.9% vs. 3.2%) were lower for the biodegradable polymer stent, but not significantly. However, the rates of target-vessel revascularization at 2 years were 2.5% versus 5.1%. The associated rate ratio of 0.52 favoring the biodegradable stent was significant.
Similar results favoring the biodegradable polymer stent were observed at 1 year, but those earlier results factored in historical data from the BIOSCIENCE trial, using a Bayesian analysis, to improve the power of the comparison. In this 2-year analysis, the superiority of the biodegradable polymer stent to the durable polymer stent remained statistically significant even when excluding those historical controls.
The advantage of the biodegradable polymer stent was confined to “device-oriented” outcomes, according to Dr. Pilgrim. When compared for important patient-oriented outcomes at 2 years, there were no significant differences. Rather, several were numerically more common, including death (4.2% vs. 3.8%) and MI (3.7% vs. 3.1%) in those who were randomized to the biodegradable polymer stent.
But these types of clinical outcomes are not necessarily related to stent assignment because “up to one-half of all events over the 2 years of follow-up were unrelated to the stent implanted,” Dr. Pilgrim said. He noted that high rates of events unrelated to the implanted stent have also been seen in follow-up of other comparative stent trials.
The superiority of the biodegradable stent is noteworthy. Although Dr. Pilgrim described the BIOSTEMI trial as “the first head-to-head comparison of two new-generation drug-eluting stents in patients undergoing a primary percutaneous intervention for acute myocardial infarction,” there have been several studies comparing stents for other indications. Significant differences have been uncommon.
“Over the last 10 years, we have seen a number of noninferiority stent trials, but only now are we seeing some superiority differences. This is a move in the right direction,” commented Sripal Bangalore, MD, director of the cardiovascular outcomes group, New York University.
However, he, like others, questioned whether the difference in outcomes in this trial could be fully attributed to the type of polymer. He noted that all stents could be characterized by multiple small and large differences in design and composition. Any specific characteristic, such as biodegradable polymer, might be an important contributor but not an isolated factor in the outcomes observed.
On the day that the 2-year results of the BIOSTEMI trial were presented at the CRT 2021 meeting they were simultaneously published in JACC: Cardiovascular Interventions.
Dr. Pilgrim reports financial relationships with several companies that make stent devices, including Biotronik and Boston Scientific. Dr. Bangalore reports no potential conflicts of interest.
For a primary composite target-lesion failure outcome, a biodegradable polymer sirolimus-eluting stent showed superiority at 2 years over a durable polymer everolimus-eluting stent in patients undergoing percutaneous intervention (PCI) for an ST-segment elevated acute myocardial infarction (STEMI), according to a late-breaking trial presentation at CRT 2021.
As in the previously reported 1-year results from the BIOSTEMI trial, the advantage of the biodegradable device was “driven by lower rates of target-lesion revascularization,” reported Thomas Pilgrim, MD, of the University of Bern (Switzerland).
Drug-eluting stents have already been established as superior to bare-metal stents, but the question asked in this study is whether the polymer that carries antiproliferative drugs, such as sirolimus or everolimus, improves lesion-based outcomes if it is biodegradable rather than durable, Dr. Pilgrim explained.
The composite primary outcome was target-lesion failure defined by cardiac death, target-lesion MI, or clinically indicated target-lesion revascularization.
After 2 years of follow-up, the rates of target-lesion failure were 5.1% and 8.1% for the biodegradable and durable polymer stents, respectively. This 0.58 rate ratio was statistically significant, favoring the biodegradable stent.
The investigator-initiated BIOSTEMI trial randomized 1,300 patients to one of two drug-eluting stents with ultrathin struts. One was the Orsiro stent that employs a biodegradable polymer to deliver sirolimus. The other was the Xience Prime/Xpedition that uses a durable polymer stent to deliver everolimus.
The strut thicknesses of the Orsiro stent are 60 mcm for stents of 3.0 mm in diameter or smaller and 80 mcm for those with a larger diameter. The strut thickness of the Xience stent is 81 mcm regardless of diameter.

Point-Counterpoint: The future of rheumatology is sub-subspecialization
Sub-subspecialization would be counterproductive: Orrin M. Troum, MD
The much-discussed looming rheumatology workforce shortage is actually here already. And it’s going to worsen rapidly. Add to that the striking geographic maldistribution of rheumatologists across the United States, and it makes little sense for some rheumatologists to declare they’re only going to see patients with psoriatic arthritis, or gout, or lupus. Such sub-subspecialization will only worsen the workforce problem, Orrin M. Troum, MD, asserted at the 2021 Rheumatology Winter Clinical Symposium.
Besides, surveys indicate that most rheumatologists like what they do now, despite their status as the lowest-paid subspecialists within internal medicine. They enjoy a sense of satisfaction stemming from their ability to help patients with chronic debilitating diseases turn their lives around as a result of revolutionary treatment advances in the last 2 decades, said Dr. Troum, a rheumatologist at the University of Southern California, Los Angeles, and in private practice in Santa Monica.
The 2015 American College of Rheumatology Workforce Study concluded that the demand for adult rheumatology services already outstripped the supply by 12.9% in 2015. And as current rheumatologists retire in tandem with a growing aged general population saddled with an accompanying burgeoning prevalence of rheumatic and musculoskeletal diseases, demand is expected to exceed supply by a whopping 102% in 2030.
The Workforce Study also highlighted the geographic maldistribution problem, with 21% of all adult rheumatologists now practicing in the Northeast and only 3.9% in the Southwest. Rheumatologists are also few and far between across large swaths of the South Central, North Central, and Northwest United States.
Today rheumatologists spend about half their working hours seeing patients with rheumatic diseases, one-quarter of their time in administrative tasks, 20% seeing patients with nonrheumatic diseases such as osteoarthritis, and the rest in teaching or research. It could be argued that, if rheumatologists declined to see patients with osteoarthritis, a nonrheumatic disease, it would put a sizeable dent in the workforce shortage, but it’s clear that nonrheumatologists can’t reliably differentiate inflammatory from noninflammatory arthritis. And there’s another problem with the idea of rheumatologists barring the office door to patients with nonrheumatic diseases: imagine a young clinical rheumatologist going out into practice and trying to tell referring internists, family physicians, and orthopedists that he or she doesn’t want to see patients with osteoarthritis, noninflammatory back pain, or fibromyalgia.
“How busy do you think you’re going to be, ever, if you tell the referring docs that you’re not going to see patients they think they need help with? And who’s going to make the correct diagnosis if we don’t at least see these patients initially?” Dr. Troum asked.
The case for sub-subspecialization: Martin J. Bergman, MD
Think about how many patients you’re treating for vasculitis, systemic lupus erythematosus, Behçet’s disease, or systemic sclerosis. Do you think you’re doing the best job that’s possible when you’re seeing just a handful of these patients, or would outcomes be better if they were seen at centers where the focus is specifically on these somewhat rare diseases? asked Martin J. Bergman, MD, a rheumatologist at Drexel University, Philadelphia, and in private practice in Ridley Park, Pa.
We can take a lesson from other specialties. It’s well-documented that higher surgical volume brings better care and better outcomes for cardiovascular and cancer surgery. Specialized high-level trauma centers achieve 20%-30% better outcomes. And outcomes are also improved when joint replacement surgery is done at specialty centers. Why would we expect rheumatology to be any different?
Actually, there is already evidence from within our own field to support this concept. A longitudinal study of 150 consecutive SLE patients – half treated at the general rheumatology clinic at Rush University, Chicago, and the other half at the medical center’s specialized lupus clinic – showed demonstrably better quality-of-care outcomes for the patients seen in the dedicated lupus clinic. They were roughly twice as likely to undergo antiphospholipid antibody testing and were also significantly more likely to have bone mineral density testing, pneumococcal vaccination, and sunscreen counseling.
Look, I get it. This is not going to be possible everywhere. In underserved geographic areas, it may not be feasible. But I would think that, even in places where you can’t have sub-subspecialty clinics, maybe it’s time for rheumatologists to start thinking in terms of sub-specializing their own practice and getting out of areas where we can make little or no impact beyond what other physicians can accomplish. Most of us provide very little value for patients with fibromyalgia and chronic fatigue syndrome. We have only so much time, and rather than taking care of anybody who has an ache or a pain we should focus on where we can make the most impact, and that’s inflammatory disease.
The speakers reported having no financial conflicts regarding their presentations.
