Additional analyses of a postmarketing trial that was required after the Food and Drug Administration’s approval of the Janus kinase inhibitor tofacitinib (Xeljanz, Xeljanz XR) has identified characteristics of older patients with rheumatoid arthritis with at least one cardiovascular risk factor who may be at higher risk for major adverse cardiovascular events (MACE) when taking the drug.

Results from the phase 3b/4 ORAL Surveillance trial presented at the virtual annual meeting of the American College of Rheumatology show that people taking tofacitinib for RA with at least one cardiovascular (CV) risk factor had a nonsignificant higher risk for MACE than did people taking tumor necrosis factor inhibitors (TNFi), with the risk from tofacitinib more pronounced in current smokers, aspirin users, people older than 65 years, and men, compared with women.

“It is the first large, randomized safety study of active RA patients with increased CV risk comparing tofacitinib to TNF inhibition,” study author Christina Charles-Schoeman, MD, said in an interview. “These data emphasize the importance of assessing baseline CV risk when treating patients with RA.” Dr. Charles-Schoeman is chief of rheumatology at the University of California, Los Angeles.

The results shed further light on the trial’s findings, which the FDA used in September 2021 to mandate boxed warnings about the risk of MI or stroke, cancer, venous thromboembolism, and death, as well as updated indications, for tofacitinib and other JAK inhibitors baricitinib (Olumiant) and upadacitinib (Rinvoq). The FDA limited all approved uses of these three medications to patients who have not responded well to TNFi to ensure their benefits outweigh their risks.

Tofacitinib is indicated for RA, psoriatic arthritis, ulcerative colitis, and polyarticular course juvenile idiopathic arthritis. Baricitinib and upadacitinib are approved only for RA.

While the overall results of the trial results show nonsignificant increased incidence rates for MACE in tofacitinib users versus TNFI users, Katherine Liao, MD, a rheumatologist at Brigham and Women’s Hospital in Boston, noted that more information is needed to determine who is at greatest risk. “Another thing to keep in mind is, while there was evidence of an elevated relative risk for MACE, compared to TNFi, the absolute risk, based on the numbers what we know so far, is small,” she said.

The trial compared two different doses of tofacitinib – 5 mg (1,455 patients) and 10 mg (n = 1,456) twice daily – and TNFi (n = 1,451) in people with moderate to severe RA over age 50. Patient characteristics were similar across all three treatment arms, Dr. Charles-Schoeman said. All patients had inadequate response to methotrexate, and about 57% in all three treatment groups were taking corticosteroids. The 10-mg tofacitinib patients switched to the 5-mg dose in February 2019 but represent the 10-mg group in the study analysis.

ORAL Surveillance demonstrated a 24% greater risk of MACE in the 5-mg tofacitinib patients and a 43% heightened risk the 10-mg group, compared with patients who received a TNFi.

The differentiating factor for MACE incidence was MI. The higher- and lower-dose tofacitinib groups had 69% and 80% greater risk for MI. While the risk for fatal MI were similar across all three treatment groups, the risk for nonfatal MI were more than doubled in the respective tofacitinib groups: hazard ratios of 2.32 and 2.08. The incidence of stroke was similar across all three arms, Dr. Charles-Schoeman said.

The study identified a number of baseline characteristics as independent overall risk factors for MACE across all treatment groups. Current smoking and aspirin use more than doubled the risk (HR, 2.18; P < .0001 and HR, 2.11; P = .004, respectively), while age greater than 65 years and male sex approached that level (HR, 1.81; P = .0011 and HR, 1.81; P = .0015) approached that level. Other factors that elevated the risk of MACE to a lesser extent were a history of diabetes, hypertension or coronary artery procedures, and a total cholesterol to HDL ratio greater than4.

Other ORAL Surveillance subanalyses and tofacitinib real-world data reported

This was one of several analyses presented at ACR 2021 that compared adverse event risks for tofacitinib versus TNFi drugs. A separate analysis of claims data from patients with RA in two U.S. insurance databases plus Medicare found a statistically nonsignificant increased risk of adverse CV outcomes (MI or stroke) with tofacitinib, compared with TNFi users, among patients who met the same inclusion and exclusion criteria of the ORAL Surveillance trial but not in a “real-world evidence” cohort of more than 102,000 patients with RA in routine care from the databases.

Two additional ORAL Surveillance analyses presented at ACR 2021 gave details about risk factors for higher rates of malignancies and venous thromboembolic events found in patients taking tofacitinib with at least one CV risk factor. As would be expected, older age (≥65 vs. 50-64 years) and current or past smoking (vs. never smoking) were independent risk factors for higher malignancy rates across all treatment arms. Pulmonary embolism events across treatment groups were independently associated with a history of venous thromboembolism, baseline use of oral contraceptives or hormone replacement therapy, baseline body mass index of at least 30 kg/m², age 65 or older, and history of hypertension.

The ORAL Surveillance findings are worth considering when determining treatments for RA patients with CV risk factors, Dr. Charles-Schoeman said. “Tofacitinib remains an effective RA treatment,” she said. “The choice of specific RA treatment for any patient remains an individual decision between the patient and physician, which is decided based on a number of different factors. This new study provides additional information regarding both tofacitinib as well as traditional CV risk factors for discussion with the patient.”

The ORAL Surveillance results may give rheumatologists reason to rethink use of tofacitinib in some patients with CV risk, said Dr. Liao of Brigham and Women’s Hospital in Boston. “Currently, we have limited data and are still awaiting a report of the full trial results,” she said in an interview. “Based on the data available, I can think of a few patients in my clinic where I would reconsider use of these drugs, i.e., history of heart attack with stable angina, especially if there are other options.” However, she noted that many patients on tofacitinib have already failed on older treatments.

These data emphasize the importance of addressing CV risk with patients, said Brittany N. Weber, MD, PhD, a cardio-rheumatologist at Brigham and Women’s Hospital who works with Dr. Liao. “It is also an opportunity to discuss modification of risk factors and to discuss primary prevention therapies, such as statin therapy, where appropriate,” she added. “Based on the individual’s cardiovascular risk, there may be a role for further risk stratification to further understand an individual’s risk, which can also inform primary prevention cardiovascular therapies and help guide these discussions.” Risk stratification could include cardiac CT for calcium scoring or cardiac coronary CT angiography for determining atherosclerotic burden.

The study was sponsored by Pfizer. Dr. Charles-Schoeman disclosed relationships with AbbVie, Bristol-Myers Squibb, Gilead Sciences, Pfizer, and Regeneron-Sanofi. Dr. Liao and Dr. Weber have no relevant disclosures.

Rituximab didn’t perform any worse or better at inducing remission after a year in patients with eosinophilic granulomatosis with polyangiitis (EGPA) than did conventional treatment with cyclophosphamide in the phase 3 REOVAS trial conducted in France.

The B-cell–depleting agent also had a safety profile similar to cyclophosphamide during that window of time, Benjamin Terrier, MD, PhD, said in presenting results of the trial at the virtual annual meeting of the American College of Rheumatology. He is a professor of rheumatology at Cochin Hospital in Paris, the University of Paris, and vice president of the French Vasculitis Study Group.

“So some of the major adverse events that we can consider with this treatment, especially with cyclophosphamide and specifically the fertility issues and the cancer issues, the follow-up of this study does not allow us to evaluate the potential benefit of rituximab over cyclophosphamide,” Dr. Terrier said in an interview.

“But on the short-term study of 1 year, for which the major adverse events are infections, there is almost no difference between the two treatments,” he said. A total of 11 patients taking rituximab and 9 patients taking cyclophosphamide had infections in the study period.

The REOVAS trial randomly assigned 105 adult patients with EPGA, otherwise known as Churg-Strauss syndrome, to either rituximab (52 patients) or the conventional strategy using cyclophosphamide (53). The patients had either newly diagnosed or relapsing disease. There was no significant differences in average daily glucocorticoid use between the two arms.

Patient characteristics were similar in both arms, including the percentages of patients with severe disease. Overall, 60% in each group had a Five-Factor Score (FFS) of 0, while the remainder had an FFS greater than 1. The FFS is calculated by giving 1 point for the presence of each of the following: proteinuria greater than 1 g/day, serum creatinine greater than 140 micromol/L, GI involvement, cardiomyopathy, and CNS involvement. The presence of each FFS component was similar between the groups at baseline, although 25% of the rituximab group and 30.2% of the conventional arm had myeloperoxidase-positive antineutrophilic cytoplasmic antibodies, and the absolute eosinophil count was 180 per mm³ in the former and 300 per mm³ in the latter.

Treatment outcomes at 6 months and 1 year were similar in both groups. At 1 year, remission occurred in 59.6% with rituximab and 64.2% with cyclophosphamide, Birmingham Vasculitis Activity Score equaled 0 in 85.7% with rituximab and 86.5% with cyclophosphamide, and prednisone dose was less than 7.5 mg/day in 77.1% with rituximab and 71.2% with cyclophosphamide.

The cumulative total weeks of complete remission was about 16 weeks in each group. Relapse-free survival, prednisone dosage, quality of life, and disease sequelae patterns also were similar.

Tailor treatment choice to the patient

Despite the equivocal findings between the two treatments, Dr. Terrier said there may be individual patients for whom rituximab would be preferred to cyclophosphamide. “It’s not dependent on the disease by itself but more on the patients we want to treat,” he said. “And clearly if there is a young female patient who wants to get pregnant, knowing that rituximab is not superior but does not appear to be inferior to cyclophosphamide can be interesting.”

The researchers opted to test the superiority rather than noninferiority of rituximab versus cyclophosphamide because a noninferiority design would have required a larger patient population, “which is not possible for a disease like this one,” he said.

“Ostensibly, [the trial] failed to show superiority, but given its favorable side-effect profile, it may be sufficient to show it’s more or less the same,” Michael Putman, MD, MSc, an associate professor and director of the vasculitis program at the Medical College of Wisconsin, Milwaukee, said in an interview. However, he noted that the study didn’t include some phenotypes seen in patients with EGPA, “in particular patients with neurological involvement.”

Dr. Putman added that the French REOVAS findings support recommendations in the 2021 ACR/Vasculitis Foundation guideline for using rituximab as a possible first-line agent to induce remission in severe granulomatosis with polyangiitis and microscopic polyangiitis. “I was somewhat surprised by that,” he said of the ACR/VF recommendation. “These are the best data to date comparing rituximab to cyclophosphamide in EGPA. I would feel more comfortable using rituximab in cases where previously I would have reached for cyclophosphamide.”

He also concurred with Dr. Terrier’s comment that rituximab may be preferred in people of child-bearing age, even extending that to men. “Cyclophosphamide can be quite toxic in terms of ovarian toxicity and premature ovarian failure,” he said. “Young men or women of child-bearing age are a group in whom I would strongly consider using rituximab.”

The French REOVAS investigators’ future research into rituximab for EGPA will include long-term follow-up for relapse and the induction of remission, Dr. Terrier said.

The FFS is calculated by giving 1 point for the presence of each of the following: proteinuria greater than 1 g/day, serum creatinine greater than 140 micromol/L, GI involvement, cardiomyopathy, and CNS involvement. The presence of each FFS component was similar between the groups at baseline, although 25% of the rituximab group and 30.2% of the conventional arm had myeloperoxidase-positive antineutrophilic cytoplasmic antibodies, and the absolute eosinophil count was 180 per mm³ in the former and 300 per mm³ in the latter.

Treatment outcomes at 6 months and 1 year were similar in both groups. At 1 year, remission occurred in 59.6% with rituximab and 64.2% with cyclophosphamide, Birmingham Vasculitis Activity Score equaled 0 in 85.7% with rituximab and 86.5% with cyclophosphamide, and prednisone dose was less than 7.5 mg/day in 77.1% with rituximab and 71.2% with cyclophosphamide.

The cumulative total weeks of complete remission was about 16 weeks in each group. Relapse-free survival, prednisone dosage, quality of life, and disease sequelae patterns also were similar.

Tailor treatment choice to the patient

Despite the equivocal findings between the two treatments, Dr. Terrier said there may be individual patients for whom rituximab would be preferred to cyclophosphamide. “It’s not dependent on the disease by itself but more on the patients we want to treat,” he said. “And clearly if there is a young female patient who wants to get pregnant, knowing that rituximab is not superior but does not appear to be inferior to cyclophosphamide can be interesting.”

The researchers opted to test the superiority rather than noninferiority of rituximab versus cyclophosphamide because a noninferiority design would have required a larger patient population, “which is not possible for a disease like this one,” he said.

“Ostensibly, [the trial] failed to show superiority, but given its favorable side-effect profile, it may be sufficient to show it’s more or less the same,” Michael Putman, MD, MSc, an associate professor and director of the vasculitis program at the Medical College of Wisconsin, Milwaukee, said in an interview. However, he noted that the study didn’t include some phenotypes seen in patients with EGPA, “in particular patients with neurological involvement.”

Dr. Putman added that the French REOVAS findings support recommendations in the 2021 ACR/Vasculitis Foundation guideline for using rituximab as a possible first-line agent to induce remission in severe granulomatosis with polyangiitis and microscopic polyangiitis. “I was somewhat surprised by that,” he said of the ACR/VF recommendation. “These are the best data to date comparing rituximab to cyclophosphamide in EGPA. I would feel more comfortable using rituximab in cases where previously I would have reached for cyclophosphamide.”

He also concurred with Dr. Terrier’s comment that rituximab may be preferred in people of child-bearing age, even extending that to men. “Cyclophosphamide can be quite toxic in terms of ovarian toxicity and premature ovarian failure,” he said. “Young men or women of child-bearing age are a group in whom I would strongly consider using rituximab.”

The French REOVAS investigators’ future research into rituximab for EGPA will include long-term follow-up for relapse and the induction of remission, Dr. Terrier said.

Immunosuppressed patients with autoimmune diseases who received the Moderna mRNA-1273 SARS-CoV-2 two-dose vaccine series had a frequency of adverse events similar to the general population albeit with a somewhat reduced, but still significant, antibody response with no severe vaccine-related disease flares, results of a prospective, nonrandomized open-label comparative trial in Canada demonstrated.

At the same time, patients with RA who were taking rituximab and patients with systemic lupus erythematosus (SLE) who were taking mycophenolate mofetil seemed to have reduced humoral responses after receiving the vaccine, said Ines Colmegna, MD, reporting results of the COVID-19 Vaccine in Immunosuppressed Adults with Autoimmune Disease (COVIAAD) study as a late-breaking poster abstract at the virtual annual meeting of the American College of Rheumatology. Dr. Colmegna is an associate professor of rheumatology in the division of experimental medicine at McGill University, Montreal.

“The frequency of adverse events, specifically the reactogenicity in people with comorbid conditions regardless of their diagnosis, was similar to healthy controls in this study, and their frequency was similar also the initial studies in the general population,” Dr. Colmegna said.

COVIAAD prospectively enrolled 220 fully vaccinated patients, 162 with rheumatic disease (131 with RA, 23 with SLE, and 8 with other diseases) and 58 controls. Adverse events a week and a month after each dose was the primary outcome. The postvaccine presence of the IgG antibody against the SARS-CoV-2 spike protein and the receptor binding domain (IgG-RBD) was the secondary outcome. Dr. Colmegna said that the study will continue evaluating participants after they get a third dose.

The Canadian trial appears to validate the ACR’s COVID-19 vaccine guidance, the fourth version of which was issued in October, said Jeffrey Curtis, MD, MS, MPH, professor of immunology and rheumatology at the University of Alabama at Birmingham and lead of the ACR COVID-19 Vaccine Guidance Task Force. Specifically, the guidance recommends that patients on rituximab or other anti-CD20 B-cell–depleting agents discuss vaccine timing with their rheumatologist.

“A few things changed over time when there was a paucity of evidence for any vaccine, but as time has gone on, mostly we were more correct than we weren’t,” Dr. Curtis said of the task force’s work. “The evidence that now is in this poster with regard to systemic lupus erythematosus and mycophenolate mofetil is [that] you have impaired vaccine response. If you’re on a B-cell drug like rituximab, you really have impaired vaccine response.”

In the study, 100% of controls had immunogenicity in terms of anti-spike and anti-RBD levels after the first and second dose. The rate of immunogenicity after the first and second dose were 67% and 88% in all patients with RA, and 35% and 78% in patients with SLE who were taking mycophenolate mofetil. The subset of patients with RA on rituximab (n = 17) had rates of immunogenicity of 5.9% and 17.6%, respectively.

“Measured antibody response is not the only way in which people develop a response to a vaccine, and there are also similar responses that occur even in people who are on rituximab and have not developed antibodies,” Dr. Colmegna said. “That’s a very important message also that we need to convey to patients: The immune response really extends beyond antibody protection.”

Overall, disease activity in both patients with RA and SLE did not appreciably change from baseline within 7 days and 28 days of each vaccine dose.

The study raises important questions about the timing of the vaccine, particularly in patients on rituximab, Dr. Colmegna said in an interview. “In theory, there is no element to suggest that, if you would schedule the vaccine a month prior to the next dose of rituximab, the effect of the drug would have decreased the number of B cells, and that the possibility of developing antibodies in response to the vaccine might be better if you give rituximab a month later when the amount of the drug and the effect of the drug is maximal,” she said. The average interval between patients receiving rituximab and vaccines was 4.5 months, Dr. Colmegna said in answering a question after her presentation.

Dr. Curtis said that the effect of holding rituximab or the vaccine to boost antibodies “is somewhat yet unknown. We think it will help, but that’s not a guarantee,” he said. “We don’t have direct evidence that just because the drug impairs vaccine response, that holding that drug for a week or 2 is going to take care of the problem.”

The study does arm rheumatologists with more information for discussing COVID vaccines with vaccine-hesitant patients with autoimmune diseases, Dr. Curtis said.

“It gives them evidence that for most of our immunomodulatory drugs the vaccine works pretty well,” he said. “The poster provides evidence that, compared to healthy controls, the vaccine doesn’t work quite as well in some patients, but for most people it actually did work pretty well. That reinforces the message: Go get vaccinated because [you] will mount [an immune] response, even, if that response isn’t quite as brisk as it is in healthy people.”

Dr. Colmegna and Dr. Curtis have no relevant relationships to disclose. The study received funding from Health and Social Services Quebec.

The use of statins by patients with rheumatoid arthritis appears to provide an overall net benefit on cardiovascular disease outcomes that outweighs the risk of type 2 diabetes mellitus (T2DM) seen with the drugs in the general population, according to evidence from a cohort study of more than 16,000 people in the United Kingdom that was presented at the virtual annual meeting of the American College of Rheumatology.

“Our study emphasizes that RA patients should be assessed for statin initiation to improve CVD risk,” lead study author Gulsen Ozen, MD, a third-year resident at the University of Nebraska, Omaha, said in an interview. Because the risk of T2DM with statin use is no worse in patients with RA than in the general population, statin initiation “is actually a great opportunity to address the risk factors for T2DM such as activity and exercise, obesity and weight loss, and [use of glucocorticoids], which have other important health effects,” she said.

“Also, importantly, even if [patients] develop T2DM, statins still work on CVD and mortality outcomes as in patients without diabetes,” Dr. Ozen added. “Given all, the benefits of statins way outweigh the hazards.”

Dr. Ozen said this was the first large cohort study to evaluate CVD mortality and T2DM risks with statins in patients with RA, a claim with which rheumatologist Elena Myasoedova, MD, PhD, of the Mayo Clinic in Rochester, Minn., concurred.

Dr. Myasoedova, professor of rheumatology and epidemiology at Mayo, said in an interview that the study was “methodologically rigorous” using time-conditional propensity score (TCPS) matching and a prevalent new-user design, “thus addressing the immortal time bias” found in the design of studies in which patients enter a cohort but do not start a treatment before developing the outcome of interest and are assigned to the untreated group or when the period of delay from when patients enter the cohort to when they are treated is excluded from the analysis. An earlier study from the same authors did not use TCPS matching, she said.

“The study findings suggest that patients with RA can benefit from statin use in terms of CVD outcomes and mortality but physicians should use vigilance regarding increased T2DM risk and discuss this possibility with patients,” Dr. Myasoedova said. “Identifying patients who are at higher risk of developing T2DM after statin initiation would be important to personalize the approach to statin therapy.”
 

Study details

The study accessed records from the U.K. Clinical Practice Research Datalink and linked Hospital Episode Statistics and Office of National Statistics databases. It analyzed adult patients with RA who were diagnosed during 1989-2018 in two cohorts: One for CVD and all-cause mortality, consisting of 1,768 statin initiators and 3,528 TCPS-matched nonusers; and a T2DM cohort with 3,608 statin initiators and 7,208 TCPS-matched nonusers.

In the entire cohort, statin use was associated with a 32% reduction in CV events (composite endpoint of the nonfatal or fatal MI, stroke, hospitalized heart failure, or CVD mortality), a 54% reduction in all-cause mortality, and a 33% increase in risk for T2DM, Dr. Ozen said. Results were similar in both sexes, although CV event reduction with statins in men did not reach statistical significance, likely because of a smaller sample size, she said.

Patients with and without a history of CVD had a similar reduction in CV events and all-cause mortality, and risk for T2DM increased with statins, but the latter reached statistical significance only in patients without a history of CVD, Dr. Ozen said.

Patients with RA who are at risk for T2DM and who are taking statins require blood glucose monitoring, which is typically done in patients with RA on disease-modifying antirheumatic drugs, and hemoglobin A1c testing when glucose levels are impaired, she said. “Any concerns for T2DM would be also communicated by the primary care providers of the patients to initiate further assessment and management,” she said.

But Dr. Ozen noted that confusion exists among primary care physicians and rheumatologists about who’s responsible for prescribing statins in these patients. “I would like to remind you that instead of assigning this role to a certain specialty, just good communication could improve this care gap of statin underutilization in RA,” she said. “Also, for rheumatologists, given that all-cause mortality reduction with statins was as high as CV event reduction, statins may be reducing other causes of mortality through improving disease activity.”

Early intervention with the immunomodulator abatacept (Orencia) may enable people at risk for rheumatoid arthritis but who don’t yet manifest symptomatic inflammation to either avoid or delay the onset of full-blown, symptomatic rheumatoid arthritis, early results of a European clinical trial have shown.

Early results of the ARIAA study, presented at the virtual annual meeting of the American College of Rheumatology, showed that among patients considered at-risk for RA and having arthralgia and subclinical inflammation – considered symptomatic but not having full-blown RA – 61% of those who received a 6-month course of abatacept versus 31% of the placebo group had an improvement in MRI inflammation score (P = .0043), said Juergen Rech, MD, a rheumatologist at Friedrich-Alexander University of Erlangen-Nuremberg (Germany) and University Clinic Erlangen.

“When we actually talk about early treatment, this may be not early enough or at least could be improved,” Dr. Rech said in an interview when asked what the findings add to the evidence for treating at-risk RA patients before disease onset. “It seems as if we were in the situation of delaying the development of disease or possibly even preventing it in some patients, and in our trial this approach was safe with abatacept.”

ARIAA randomized 100 patients to abatacept or placebo at 14 study sites between November 2014 and December 2019. The goal is to treat at-risk patients for 6 months with abatacept, then follow them for 12 months to determine their progression to RA. Dr. Rech noted that 8% of patients in the treatment group and 35% in the placebo group developed arthritis (P = .0025).

He noted that the safety profile of abatacept in this patient population was similar to previous trials. “No safety issues emerged,” Dr. Rech said.

The investigators used MRI to determine the patients’ status for arthralgia and subclinical inflammation before enrollment. They had no history of clinically obvious inflammation fulfilling the criteria for RA and no previous treatment with glucocorticoids or disease-modifying antirheumatic drugs.

The results showed that abatacept is superior to placebo in improving subclinical inflammation and in inhibiting the progression to RA in at-risk patients at 6 months, Dr. Rech said, but early clinical results of patients in the study who’ve had 18 months of follow-up, which were not part of the dataset he presented, revealed that time-limited treatment with the immunomodulator has a significant sustained effect on progression to RA. That “means 6 months of treatment with abatacept will delay the development of RA after 18 months,” he said.

After the complete 18-month dataset is analyzed, the next step for investigators will be to re-evaluate the ARIAA population, perhaps for genetic markers, Dr. Rech said. What would then follow, he said, could be to conduct a larger phase 3 trial, determine the risk factors that drive RA autoimmunity, see if disease progression varies among ethnic groups and people in different geographic regions, and perhaps start a head-to-head trial with rituximab (Rituxan) or an evaluation of combined time-limited abatacept and rituximab in at-risk patients.

“We should think about new strategies, new life-quality questionnaires, new biomarkers and tools for covering and understanding these RA patients at-risk in a better way,” Dr. Rech said, noting that a European Alliance of Associations for Rheumatology task force has already addressed this topic.

John D. Isaacs, MBBS, PhD, professor of rheumatology at Newcastle (England) University, said in an interview that ARIAA is the first readout from a number of studies evaluating preemptive treatment to prevent or delay RA onset. “You have to ask a question: Is this just suppressing what’s going on?” Dr. Isaacs said. “In other words, now that the treatment has been stopped, there’s great interest in what happens over the next 12 months of this study. Have we delayed the onset of rheumatoid arthritis or have we actually prevented it? I think that’s the $10 billion dollar question of this and similar studies.”

Answering that question may be difficult without a known blood biomarker. “That’s not a criticism of the trial; we just don’t have that scientifically at the moment,” Dr. Isaacs said. “Until then, it will be difficult to say we have delayed or we have prevented rheumatoid arthritis. My feeling is, even if we delay it 6 months or even a year with safe treatment, that would be worth it.”

Bristol-Myers Squibb sponsored the trial. Dr. Rech and Dr. Isaacs disclosed having financial relationships with Bristol-Myers Squibb and other pharmaceutical companies.

Early intervention with the immunomodulator abatacept (Orencia) may enable people at risk for rheumatoid arthritis but who don’t yet manifest symptomatic inflammation to either avoid or delay the onset of full-blown, symptomatic rheumatoid arthritis, early results of a European clinical trial have shown.

Early results of the ARIAA study, presented at the virtual annual meeting of the American College of Rheumatology, showed that among patients considered at-risk for RA and having arthralgia and subclinical inflammation – considered symptomatic but not having full-blown RA – 61% of those who received a 6-month course of abatacept versus 31% of the placebo group had an improvement in MRI inflammation score (P = .0043), said Juergen Rech, MD, a rheumatologist at Friedrich-Alexander University of Erlangen-Nuremberg (Germany) and University Clinic Erlangen.

“When we actually talk about early treatment, this may be not early enough or at least could be improved,” Dr. Rech said in an interview when asked what the findings add to the evidence for treating at-risk RA patients before disease onset. “It seems as if we were in the situation of delaying the development of disease or possibly even preventing it in some patients, and in our trial this approach was safe with abatacept.”

ARIAA randomized 100 patients to abatacept or placebo at 14 study sites between November 2014 and December 2019. The goal is to treat at-risk patients for 6 months with abatacept, then follow them for 12 months to determine their progression to RA. Dr. Rech noted that 8% of patients in the treatment group and 35% in the placebo group developed arthritis (P = .0025).

He noted that the safety profile of abatacept in this patient population was similar to previous trials. “No safety issues emerged,” Dr. Rech said.

Following up on its 2007 initiative to improve care for people who have ST-segment elevation myocardial infarction (STEMI), the American Heart Association has issued a policy statement that includes a host of recommendations to further overcome barriers to optimal care for this most severe type of heart attack.

American Heart Association

The statement recommends steps for designing what the writing committee calls “the ideal STEMI system of care” for patients who have these severe heart attacks.

The focus of the policy statement is the AHA’s Mission: Lifeline national initiative to coordinate and improve the quality of care to patients with STEMI, which was introduced in 2007. Since then, the number or participating hospitals has increased from 485 to 857, now covering more than 85% of the U.S. population, noted the new statement, published online in Circulation.

“Bringing STEMI referring hospitals, STEMI receiving centers and emergency medical services [EMS] together in the development of local and regional systems of care within the AHA’s Mission: Lifeline program has led to significant improvement in time to treatment and outcomes for patients with STEMI,” Alice K. Jacobs, MD, lead statement author and vice chair for clinical affairs in the department of medicine at Boston Medical Center and a professor at Boston University, said in an interview.

“Yet,” Dr. Jacobs added, “opportunities exist to further improve the coordination of care and address remaining barriers to providing ideal care. Moreover, Mission: Lifeline systems of care have been extended to other time-sensitive cardiovascular disorders including stroke and out-of-hospital cardiac arrest.”

The statement itself noted, “Although there have been significant improvements in patients with STEMI receiving guideline-recommended care, progress has slowed during the past few years.” From 2008 to 2012, a number of key quality care measures at participating hospitals had improved markedly. For example, door-in-door-out (DIDO) transfers improved from a median of 76 to 62 minutes (P < .001).

However, from 2012 to 2019, with more hospitals participating, while many key measures improved, a few either plateaued or worsened slightly. Median DIDO time, for example – again, with more hospitals participating, compared with the earlier dataset – went from 45 in 2012 to 48 in 2019, according to AHA data.

Key recommendations aim to impact and improve hospital care for patients with STEMI, Dr. Jacobs said. “In addition to avoiding patient delay at the onset of recognized symptoms of a heart attack, accessing 911 and following EMS destination protocols, the prehospital activation of the cardiac catheterization lab and providing a 911 response for interhospital transport as well as direct-to-cardiac-catheterization-lab transport bypassing the emergency department when appropriate would all impact and improve hospital care.”

Other key recommendations of the statement include:

• Increasing public awareness of heart attack signs and symptoms and the importance for calling 911.
• Addressing post-MI care, including use of evidence-based practices for cardiac rehabilitation and even getting insurance companies to encourage cardiac rehab through incentives.
• Engaging rural hospitals by leveraging telemedicine to expedite percutaneous coronary intervention (PCI) and by developing systems for treatment protocols and rapid transport among facilities.
• Tearing down financial barriers with a global reimbursement model that encompasses each stop in a patient’s journey through the care system: the referring hospital, receiving center, EMS transport and transfer, and ancillary services.

The statement also took into account improving disparities in the quality of care women with STEMI receive. “It has been reported that women with STEMI may have less typical symptoms than men and arrive later [delay longer] than men after symptom onset,” Dr. Jacobs said. “Educating the public and all members of the health-care team about issues specific to women will be helpful in improving care in women. Of note, STEMI systems of care have been shown to reduce sex and age disparities in care.”

The statement also addressed implications of the COVID-19 pandemic, stating that PCI should remain the dominant treatment for patients with classic STEMI. “Patients must be reassured that appropriate precautions have been implemented by EMS and hospital to protect them and health care workers from COVID-19 infection,” the statement noted.

Dr. Jacobs has no relevant relationships to disclose.

Social distancing and the shutdown of services like physical and occupational therapy because of COVID-19 have had a profound impact on the mental health of people with Parkinson’s disease, a team of researchers in the Netherlands reported, but they also identified meaningful targets for intervention.

Lisanne Dommershuijsen, MSc, a PhD candidate and researcher in epidemiology at the Erasmus University Medical Center in Rotterdam, the Netherlands, reported on a cross-sectional study of 833 participants with Parkinson’s disease in the PRIME-NL study at the International Congress of Parkinson’s Disease and Movement Disorders. The average age of participants was 70.2 and 38% were women.

“We studied targeted hypothetical interventions on COVID-19 stressors in people with Parkinson’s disease,” Ms. Dommershuijsen said. “This disruption in normal life caused considerable psychological stress in community-dwelling individuals. People with Parkinson’s disease might be especially vulnerable to this stress.

“For instance, because reduced levels of physical activity have worsened symptoms or because people with Parkinson’s often have difficulty with flexible [adaptations] to drastic and rapid changes in daily routines, such as those introduced by the COVID-19 pandemic, previous studies found that COVID-19 worsened depression and anxiety symptoms and reduced quality of life (QOL) in people with Parkinson’s disease,” Ms. Dommershuijsen said.

Hence, the goal of the study was to identify the most vulnerable subgroups in the Parkinson’s population and to suggest potential interventions to ameliorate these impacts, she said.

The study focused on eight different stressors that emerged in the pandemic: access to care, medicine and nursing services; loss of social contact; canceled social events; tension or conflict in the home; inability to perform physical activity or relax; and COVID-19 symptoms. The outcomes of interest were depression, as measured with the Beck Depression Inventory (BDI); anxiety, as measured with the Spielberger State-Trait Anxiety Inventory (STAI); and QOL, with the Parkinson’s Disease Quality of Life Questionnaire. The aggregate resulted in a scale of 0-40, with the mean stressor score in the study being 9.6, Ms. Dommershuijsen said.

The BDI and STAI scores for social stressors – loss of social contacts, social events canceled and tension or conflict at home – exceeded those for the so-called care stressors – problems accessing care, medication or nursing – she said, although all eight stressors yielded higher BDI and STAI scores across the board.
 

Vulnerable subgroups

“When we looked at vulnerable subgroups of people with Parkinson’s disease, we found more pronounced associations between the COVID-19 stress and mental health in women, in highly educated participants, and in participants with advanced Parkinson’s disease,” Ms. Dommershuijsen said. The impact on women and people with advanced disease is explainable, Ms. Dommershuijsen added in an interview; the former because depressive symptoms are more common in women, and the latter because loss of access to care impacts mental wellness.

“The finding that social stressors were more related to anxiety in highly educated people was surprising to us, given that depression in general is more common in people with a lower education,” she said in an interview. “One previous study of the general population suggested this might be related to expectations about available resources, but this findings and the possible explanation warrants further investigation.”

When the study stratified for coping strategies, the COVID-19 stressors had a smaller effect on depressive and anxiety symptoms in Parkinson’s disease patients prone to confrontive coping and planful problem solving, she said. “Whereas, we observed a larger effect of these stressors in people who are prone to using distancing or seeking social support as coping mechanisms,” Ms. Dommershuijsen said.

The researchers also created a model of a hypothetical 50% reduction in COVID-19 stressors among all study participants, but the effect wasn’t clinically relevant, Ms. Dommershuijsen said. However, in people with advanced Parkinson’s disease – that is, with an Movement Disorder Society–Unified Parkinson Disease Rating Scale score above median – the effect was clinically relevant in all outcomes.

The potential interventions the study identified were telemedicine via virtual consultations to alleviate care stressors, and virtual support groups and online classes to address social stressors. “However, a more personalized approach is needed to target tension or conflict at home, which was the most important social stressor influencing depression and anxiety symptoms in our study,” she said. “Social work can play an important role here.”

Asked to comment on the study, Roy Alcalay, MD, professor of neurology at Columbia University Irving Medical Center in New York, said in an interview that the findings align with his research on the impact of COVID-19 and related restrictions on people with Parkinson’s disease.

“The pandemic has affected people in different ways,” he said. “Initially very acutely, people just didn’t have access to doctors. There was also the acute question in movement disorders, but also in other diseases where the people with Parkinson’s disease are going to have the worse outcome when they have COVID-19.” Dr. Alcalay authored two recent papers on the impact of COVID-19 in people with Parkinson’s disease.

“Then we see that, in addition to that question, there’s the question of even if they don’t have COVID-19, just the social distancing and the lack of access to health care, and specifically to physical and occupational therapy and other services, can be quite damaging,” he said.

What’s commendable about the study, he said, was that it just doesn’t highlight the problem. “They’re also highlighting potential solutions, that planful problem solving and coping strategies can be helpful to people.”

Neither Ms. Dommershuijsen nor Dr. Alcalay have any relevant relationships to disclose.

Social distancing and the shutdown of services like physical and occupational therapy because of COVID-19 have had a profound impact on the mental health of people with Parkinson’s disease, a team of researchers in the Netherlands reported, but they also identified meaningful targets for intervention.

Lisanne Dommershuijsen, MSc, a PhD candidate and researcher in epidemiology at the Erasmus University Medical Center in Rotterdam, the Netherlands, reported on a cross-sectional study of 833 participants with Parkinson’s disease in the PRIME-NL study at the International Congress of Parkinson’s Disease and Movement Disorders. The average age of participants was 70.2 and 38% were women.

“We studied targeted hypothetical interventions on COVID-19 stressors in people with Parkinson’s disease,” Ms. Dommershuijsen said. “This disruption in normal life caused considerable psychological stress in community-dwelling individuals. People with Parkinson’s disease might be especially vulnerable to this stress.

“For instance, because reduced levels of physical activity have worsened symptoms or because people with Parkinson’s often have difficulty with flexible [adaptations] to drastic and rapid changes in daily routines, such as those introduced by the COVID-19 pandemic, previous studies found that COVID-19 worsened depression and anxiety symptoms and reduced quality of life (QOL) in people with Parkinson’s disease,” Ms. Dommershuijsen said.

Hence, the goal of the study was to identify the most vulnerable subgroups in the Parkinson’s population and to suggest potential interventions to ameliorate these impacts, she said.

The study focused on eight different stressors that emerged in the pandemic: access to care, medicine and nursing services; loss of social contact; canceled social events; tension or conflict in the home; inability to perform physical activity or relax; and COVID-19 symptoms. The outcomes of interest were depression, as measured with the Beck Depression Inventory (BDI); anxiety, as measured with the Spielberger State-Trait Anxiety Inventory (STAI); and QOL, with the Parkinson’s Disease Quality of Life Questionnaire. The aggregate resulted in a scale of 0-40, with the mean stressor score in the study being 9.6, Ms. Dommershuijsen said.

The BDI and STAI scores for social stressors – loss of social contacts, social events canceled and tension or conflict at home – exceeded those for the so-called care stressors – problems accessing care, medication or nursing – she said, although all eight stressors yielded higher BDI and STAI scores across the board.
 

Vulnerable subgroups

“When we looked at vulnerable subgroups of people with Parkinson’s disease, we found more pronounced associations between the COVID-19 stress and mental health in women, in highly educated participants, and in participants with advanced Parkinson’s disease,” Ms. Dommershuijsen said. The impact on women and people with advanced disease is explainable, Ms. Dommershuijsen added in an interview; the former because depressive symptoms are more common in women, and the latter because loss of access to care impacts mental wellness.

“The finding that social stressors were more related to anxiety in highly educated people was surprising to us, given that depression in general is more common in people with a lower education,” she said in an interview. “One previous study of the general population suggested this might be related to expectations about available resources, but this findings and the possible explanation warrants further investigation.”

When the study stratified for coping strategies, the COVID-19 stressors had a smaller effect on depressive and anxiety symptoms in Parkinson’s disease patients prone to confrontive coping and planful problem solving, she said. “Whereas, we observed a larger effect of these stressors in people who are prone to using distancing or seeking social support as coping mechanisms,” Ms. Dommershuijsen said.

The researchers also created a model of a hypothetical 50% reduction in COVID-19 stressors among all study participants, but the effect wasn’t clinically relevant, Ms. Dommershuijsen said. However, in people with advanced Parkinson’s disease – that is, with an Movement Disorder Society–Unified Parkinson Disease Rating Scale score above median – the effect was clinically relevant in all outcomes.

The potential interventions the study identified were telemedicine via virtual consultations to alleviate care stressors, and virtual support groups and online classes to address social stressors. “However, a more personalized approach is needed to target tension or conflict at home, which was the most important social stressor influencing depression and anxiety symptoms in our study,” she said. “Social work can play an important role here.”

Asked to comment on the study, Roy Alcalay, MD, professor of neurology at Columbia University Irving Medical Center in New York, said in an interview that the findings align with his research on the impact of COVID-19 and related restrictions on people with Parkinson’s disease.

“The pandemic has affected people in different ways,” he said. “Initially very acutely, people just didn’t have access to doctors. There was also the acute question in movement disorders, but also in other diseases where the people with Parkinson’s disease are going to have the worse outcome when they have COVID-19.” Dr. Alcalay authored two recent papers on the impact of COVID-19 in people with Parkinson’s disease.

“Then we see that, in addition to that question, there’s the question of even if they don’t have COVID-19, just the social distancing and the lack of access to health care, and specifically to physical and occupational therapy and other services, can be quite damaging,” he said.

What’s commendable about the study, he said, was that it just doesn’t highlight the problem. “They’re also highlighting potential solutions, that planful problem solving and coping strategies can be helpful to people.”

An investigative formulation of a botulinum neurotoxin (BoNT) for cervical dystonia may significantly reduce the risk of dysphagia after injection compared with existing injections, and may have a longer duration of beneficial effect, according to results of a phase 3 clinical trial presented at the virtual International Congress of Parkinson’s Disease and Movement Disorders.

The ASPEN-1 trial evaluated 301 patients with moderate to severe cervical dystonia for up to 36 weeks and found that those receiving two doses of DaxibotulinumtoxinA, known as DAXI, versus placebo improved their scores on the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), said Joseph Jankovic, MD, professor of neurology and director of the Parkinson’s Disease Center and Movement Disorders Clinic at Baylor College of Medicine in Houston.

“Botulinum neurotoxin is clearly the treatment of choice for cervical dystonia,” Dr. Jankovic said in an interview. “While the majority of patients obtain satisfactory benefit from BoNT injections, some experience adverse effects such as neck weakness and difficulty swallowing.” Another limitation of BoNT is that its effects wear off after about 3 months or less and patients have to be re-injected, he said. 

“This is why I am quite encouraged by the results of the DAXI study that suggest that this formulation of BoNT (type A) may have a longer response and relatively few side effects,” he said.

Patients in the study were randomized 1:3:3 to placebo, DAXI 125U or DAXI 250U. The average TWSTRS score upon enrollment was 43.3. The placebo group had a mean ± standard error TWSTRS improvement of 4.3 ± 1.8 at 4 or 6 weeks, while the treatment groups had mean ± SE improvements of 12.7 ± 1.3 for 125U and 10.9 ± 1.2 for 250U (P = .0006 vs. placebo). They translate into improvements of 12%, 31%, and 27% for the placebo and low- and high-dose treatment groups, respectively.

“Even though paradoxically it seems the high-dose group did slightly less well than the low-dose group, there was no difference between the two groups,” Dr. Jankovic said in the presentation.

The median duration of benefit was 24 weeks in the low-dose group and 20.3 weeks in the high-dose group.

The treatment groups demonstrated similar benefit compared with placebo in TWSTRS subscales for disease severity, disability, and pain, Dr. Jankovic said. “The majority of the patients had little better, moderately better, or very much better from the botulinum toxin injection with respect to clinical global impression of change and patient global impression of change,” he said.

Likewise, both the Clinician Global Impression of Change (CGIC) and Patient Global Impression of Change (PGIC) demonstrated improvement versus placebo: 77.6% and 76.9% in the 125U and 250U doses versus 45.7% for the former; and 71.2% and 73.1% versus 41.3% for the latter.

Side effects “were remarkably minimal,” Dr. Jankovic said, “but I want to call attention to the low frequency of neck weakness or dysphagia in comparison with other studies of botulinum toxin in cervical dystonia.” The rates of dysphagia were 1.6% and 3.9% in the 125U and 250U treatment groups, respectively. Sixteen of the 255 patients in the treatment groups reported muscular weakness or musculoskeletal pain, and seven had dysphagia.

The rate of dysphagia after injection is noteworthy, said David Charles, MD, professor and vice chair of neurology at Vanderbilt University in Nashville, Tenn., who was not involved in the research. “The one thing we worry about most in people with cervical dystonia are swallowing and choking – dysphagia – and the numbers are very modest: 2 out of 127 in the 125U dose and 5 of 130 in the 250U dose,” he said. “That’s a very low rate of that adverse event.”

The duration of action for both doses is “rather remarkable,” Dr. Charles said. “With the other formulations, my patients are coming back every 12 weeks for treatment; the BoNT helps so much that [these] patients make their appointments every 3 months for as far out as they can,” he said. “This could potentially mean two or three trips a year as opposed to four trips a year.”

The trial was funded by Revance Therapeutics. Dr. Jankovic is an investigator for Revance, and three coauthors are employees of Revance. Dr. Charles is a consultant to the company.

Progress has been made over the years to recruit more diverse worldwide populations for genetic studies in Parkinson’s disease, but there is a need to break down barriers to expanding those populations beyond European ethnicity and to get clinically meaningful data out of those studies, attendees at the International Congress of Parkinson’s Disease and Movement Disorders were told.

“Through the years, as we’ve increased the number of individuals that we’ve included in our genetic studies, the number of risk factors that we’ve been able to identify has increased exponentially,” said Ignacio F. Mata, PhD, a neurogeneticist and principal investigator with the Genomic Medicine Institute of the Cleveland Clinic Lerner Research Institute. “This is all due to collaborations.”

Dr. Mata reviewed no fewer than seven initiatives that are gathering genetic data from people with Parkinson’s disease in Central and South America, India, China, Africa, Oceania, the Middle East, and Central Asia, along with efforts to target diverse populations in London and African Americans in the United States.

“One of the problems that we’ve had in the past is that most of the studies have been done just with individuals that are of European ancestry, so there’s a big gap of other populations that we haven’t been able to study,” Dr. Mata said. “And this is true for all of the current studies that are ongoing here in the United States.” That includes the Parkinson’s Progression Markers Initiative, he said, in which fewer than 6% of participants are non-European. Dr. Mata is also the lead in the Global Parkinson’s Genetics Program (GP2) for underrepresented populations.

Lack of diversity in genetic studies isn’t an issue in Parkinson’s studies alone, Dr. Mata said. “This is a generalized problem across all genetic studies,” he said, citing a 2016 analysis that found the proportion of participants in genome-wide studies was 96% European descent in 2009, shifting to 80% by 2016. “There’s still a big gap because most of the non-European populations came mostly from Asia,” Dr. Mata said, with Latinos and people of African descent representing less than 1% of the study populations.

In an interview, Dr. Mata noted there are a multitude of reasons for enrolling more diverse populations. “We’re going to be able to use genetics to create new treatments and do risk prediction – the so-called precision or personalized medicine,” he said. “We’re leaving a big chunk of the population behind if we don’t include those individuals.”
 

Scientific basis for diversity

There are a multitude of scientific reasons for doing so, too, said Dr. Mata. “In the whole genome we try to find gene variants that modify the risk for certain disease,” he said. “These regions can be quite large, so increasing the number of individuals that come from different genetic backgrounds can actually help us reduce the number of regions that need to be studied to find the causal variants.”

Andrew Singleton, PhD, director of the Center for Alzheimer’s and Related Dementias at the National Institute of Aging in Bethesda, Md., concurred that enrolling more diverse populations can speed up research for targeting genetic variants.

The synthetic medium-chain triglyceride triheptanoin has shown potential to restore brain energy and decrease caudate atrophy in Huntington’s disease, and improved motor function for up to a year, according to data presented at the International Congress of Parkinson’s Disease and Movement Disorders.

Reporting results of TRIHEP3 and an extension study, Fanny Mochel, MD, PhD, of Sorbonne University in Paris and the Paris Brain Institute, said in an interview that her group is the only one investigating triheptanoin to target caudate atrophy in Huntington’s disease. The Food and Drug Administration last year approved triheptanoin for the treatment of long-chain fatty acid oxidation disorders.

“The main findings are two observations: that patients were clinically stable based on their gradation of total motor score (TMS) on UHDRS (Unified Huntington’s Disease Rating Scale) after 1 year,” Dr. Mochel said in an interview. “The other is that we observed a reduction of the caudate atrophy progression that we usually see over 1 year by about 50%.”

TRIHEP3 randomized 100 patients with early-stage Huntington’s disease to triheptanoin 1g/kg daily and placebo. It followed on previous research in which the group used 31-phosphorus brain MR spectroscopy to demonstrate triheptanoin restored a normal brain energetic profile in patients with Huntington’s disease. TRIHEP3 was a 6-month randomized controlled trial at two centers, followed by a 6-month open-label phase. After that, 42 patients opted to participate in the 1-year extension study.

TRIHEP3 found no difference in caudate boundary shift integral (cBSI) at 6 months – the primary endpoint. But in the extension study, TMS tended to stabilize in patients treated for 1 year (0.6 ± 5.1), compared with those treated for 6 months (2.5 ± 4.5, P = .072).

Using a placebo control group from an external study of patients with Huntington’s disease with what Dr. Mochel described as “identical clinical characteristics,” she said the research confirmed TMS clinical stability in treated patients at 1 year (2.6 ± 4.6 vs. 0.6 ± 5.1, P = .057) and found significantly lower caudate atrophy (–3% vs. –6.7%, compared with baseline, P < .001).

Dr. Mochel also noted that Diffusion Tensor Imaging and Fixed-based analyses (FBA) showed fewer alterations in fiber metrics at 24 months in patients treated from baseline. FBA also showed improved fiber trophicity at 24 months in both groups.
 

‘The first good news’

Dr. Mochel noted that the Huntington’s disease community had been shaken in the spring by the failure of three trials of gene-targeting therapies for Huntington’s disease. Roche halted a phase 3 study of its antisense oligonucleotide (ASO) tominersen, and Wave Life Sciences scuttled two ASO programs in phase 1/2 trials.

“Triheptanoin is not going to cure Huntington’s disease; it’s a disease with many components, but it does work on the energy aspects and that seems to stabilize patients over the time of observation,” Dr. Mochel said. “That’s the first good news.”

She also noted that side effects were mainly gastrointestinal in nature, and they typically resolved with dietary management.

As a target in Huntington disease, the caudate nucleus is highly desirable, and caudate atrophy has been shown to occur even before the onset of motor symptoms, said N. Ahmad Aziz, MD, PhD, a neurologist and epidemiologist at the German Center for Neurodegenerative Diseases at the University of Bonn (Germany). “In this light, the findings of the trial conducted by Dr. Mochel and colleagues, which suggest that triheptanoin intake may slow down the rate of caudate atrophy in patients with early-stage Huntington’s disease, are highly promising,” Dr. Aziz said in an interview.

However, he noted that the improvement in caudate atrophy was only a secondary endpoint in the extension study. “Nevertheless, given  triheptanoin’s biologically plausible mechanism of action – i.e., provision of substrates to the Krebs cycle and at least partial restoration of the well-documented defective mitochondrial function in Huntington’s disease – combined with its apparently relatively mild side-effect profile and good tolerability, I think that the preliminary findings of this trial are very promising and justify a larger phase 3 trial,” Dr. Aziz said.

Dr. Mochel said that the findings are prompting the investigators to consider just that.

Dr. Mochel has received consulting fees from and conducted investigator‐sponsored studies supported by Ultragenyx Pharmaceuticals. Dr. Aziz has no relevant financial relationships to disclose.

Using a placebo control group from an external study of patients with Huntington’s disease with what Dr. Mochel described as “identical clinical characteristics,” she said the research confirmed TMS clinical stability in treated patients at 1 year (2.6 ± 4.6 vs. 0.6 ± 5.1, P = .057) and found significantly lower caudate atrophy (–3% vs. –6.7%, compared with baseline, P < .001).

Dr. Mochel also noted that Diffusion Tensor Imaging and Fixed-based analyses (FBA) showed fewer alterations in fiber metrics at 24 months in patients treated from baseline. FBA also showed improved fiber trophicity at 24 months in both groups.
 

‘The first good news’

Dr. Mochel noted that the Huntington’s disease community had been shaken in the spring by the failure of three trials of gene-targeting therapies for Huntington’s disease. Roche halted a phase 3 study of its antisense oligonucleotide (ASO) tominersen, and Wave Life Sciences scuttled two ASO programs in phase 1/2 trials.

“Triheptanoin is not going to cure Huntington’s disease; it’s a disease with many components, but it does work on the energy aspects and that seems to stabilize patients over the time of observation,” Dr. Mochel said. “That’s the first good news.”

She also noted that side effects were mainly gastrointestinal in nature, and they typically resolved with dietary management.

As a target in Huntington disease, the caudate nucleus is highly desirable, and caudate atrophy has been shown to occur even before the onset of motor symptoms, said N. Ahmad Aziz, MD, PhD, a neurologist and epidemiologist at the German Center for Neurodegenerative Diseases at the University of Bonn (Germany). “In this light, the findings of the trial conducted by Dr. Mochel and colleagues, which suggest that triheptanoin intake may slow down the rate of caudate atrophy in patients with early-stage Huntington’s disease, are highly promising,” Dr. Aziz said in an interview.

However, he noted that the improvement in caudate atrophy was only a secondary endpoint in the extension study. “Nevertheless, given  triheptanoin’s biologically plausible mechanism of action – i.e., provision of substrates to the Krebs cycle and at least partial restoration of the well-documented defective mitochondrial function in Huntington’s disease – combined with its apparently relatively mild side-effect profile and good tolerability, I think that the preliminary findings of this trial are very promising and justify a larger phase 3 trial,” Dr. Aziz said.

Dr. Mochel said that the findings are prompting the investigators to consider just that.

The synthetic medium-chain triglyceride triheptanoin has shown potential to restore brain energy and decrease caudate atrophy in Huntington’s disease, and improved motor function for up to a year, according to data presented at the International Congress of Parkinson’s Disease and Movement Disorders.

Reporting results of TRIHEP3 and an extension study, Fanny Mochel, MD, PhD, of Sorbonne University in Paris and the Paris Brain Institute, said in an interview that her group is the only one investigating triheptanoin to target caudate atrophy in Huntington’s disease. The Food and Drug Administration last year approved triheptanoin for the treatment of long-chain fatty acid oxidation disorders.

“The main findings are two observations: that patients were clinically stable based on their gradation of total motor score (TMS) on UHDRS (Unified Huntington’s Disease Rating Scale) after 1 year,” Dr. Mochel said in an interview. “The other is that we observed a reduction of the caudate atrophy progression that we usually see over 1 year by about 50%.”

TRIHEP3 randomized 100 patients with early-stage Huntington’s disease to triheptanoin 1g/kg daily and placebo. It followed on previous research in which the group used 31-phosphorus brain MR spectroscopy to demonstrate triheptanoin restored a normal brain energetic profile in patients with Huntington’s disease. TRIHEP3 was a 6-month randomized controlled trial at two centers, followed by a 6-month open-label phase. After that, 42 patients opted to participate in the 1-year extension study.

TRIHEP3 found no difference in caudate boundary shift integral (cBSI) at 6 months – the primary endpoint. But in the extension study, TMS tended to stabilize in patients treated for 1 year (0.6 ± 5.1), compared with those treated for 6 months (2.5 ± 4.5, P = .072).
