NASHVILLE, TENNESSEE — Individuals with multiple sclerosis are living longer, healthier lives. More than half of patients with MS are 55 years or older, and the incidence of late-onset MS is rising.
This can lead to complex treatment decisions, according to Amy Perrin Ross, APN, MSN, CNRN, MSCN, who is the neuroscience program coordinator at Loyola Medical Center in Maywood, Illinois.
said Ms. Ross, during a presentation at the annual meeting of the Consortium of Multiple Sclerosis Centers. But there is little evidence to support treatment decisions, since there are few older patients enrolled in clinical trials. The average age is around 30-34 years.
MS in Older Patients
Aging is associated with immune system changes. There is a decline in inflammatory activity and an accompanying 17% reduction in the relapse rate with every 5 years of advancing age, and the majority of relapses occur within 30 years of onset. The bad news is that patients have reduced capacity to recover from relapses as they age.
“When I’m talking to patients about pros and cons [of treatment], I do mention that, yes, your relapse rate might be less, but as we age, we have less of an ability to completely recover,” said Ms. Ross.
The efficacy of disease-modifying therapies (DMTs) goes down with advancing age. One meta-analyis of 38 randomized trials and 13 therapies found that benefit with respect to disease progression generally disappeared by the age of 53. “Age is an essential modifier of drug efficacy,” said Ms. Ross.
On the other hand, another meta-analysis found that success in treating relapses was similar across age groups. “So it seems that we can successfully treat our patients’ relapses: There was no significant association between age and reductions in annualized relapse rate,” she said, though she noted that clinical trial populations are likely to be dissimilar to aging patients, many of whom have gone years without experiencing a relapse.
Aging can also lead to differences in potential adverse effects of DMTs. Patients with MS experience faster immunosenescence, in which normal changes to the innate and adaptive immune system are accelerated. This can lead to greater risk of infection, and other adverse events can include post-administration reactions and changes to serum IgG levels.
Other conditions that should be monitored for include progressive multifocal leukoencephalopathy, and malignancies are more prevalent among people with MS than the general population, although it is unclear if this is due to the use of DMTs or other factors, or even just coincidence, said Ms. Ross. “Those are all things to keep in mind as we’re pushing forward with therapy for patients,” she said.
Comorbidities that occur with aging can also affect treatment outcomes, and could tip the balance against use of DMTs in some situations.
What Does the Literature Say?
There has been a range of retrospective studies looking at the results of discontinuation of DMTs with advancing age, and the results have been mixed. Some factors are associated with greater likelihood of disease reactivation, including younger age, female sex, shorter duration without a relapse, MRI activity, and degree of disability.
A study of a French registry including patients aged 50 years and older who went off DMTs found that 100% of patients who discontinued therapy were on older injectable DMTs, and 34.9% of that group restarted therapy over a mean follow-up of 7 years. The risk of relapse or disability progression was similar between the groups, but discontinuers who started with Expanded Disability Status Scale (EDSS) scores lower than 6.0 were more likely to reach an EDSS score of 6.0.
The DISCOMS study compared 259 patients randomized to continue DMTs versus discontinuation of DMTs. “What they found was that noninferiority was not shown. Disease activity, such as relapses and new lesions, [occurred in] 12% of the discontinuers and 5% of the continuers,” said Ms. Ross.
One option to balance risk and benefit is DMT de-escalation, with the aim to match disease therapy with disease activity over time. A 2023 survey of 224 neurologists to identify characteristics in older patients that would prompt de-escalation. The most common reasons were overall safety or comorbidity concerns (62% endorsed), high risk of infection (59%), low disease activity or stable disease (50%), concerns about efficacy (41%), high disability (37%), and patient choice (36%). About 7% reported that they generally do not de-escalate.
The preferred de-escalation therapies included glatiramer acetate (29%), fumarates (27%), teriflunomide (23%), and interferon betas (21%).
Ms. Ross noted that the study was likely conducted around the height of the COVID-19 pandemic. “So I wonder if some of these results might be a little bit different [than if it was conducted at a different time],” she said.
Other Concerns and Options
During the Q&A session, one audience member asked if physicians should consider low-efficacy medications in older patients with the idea that they at least get a little bit of protection.
Patricia Coyle, MD, who also presented during the session, framed her response around whether the patient had relapsing or progressive MS. “If somebody has had relapsing MS and has never transitioned to progressive MS, and they’re 70, maybe they don’t need to be on any DMT. If there’s no longer a focal inflammatory relapsing phase, if we could feel confident on that possibility, then maybe they don’t need to be on a relapsing DMT,” said Dr. Coyle, who is director of the MS Comprehensive Care Center at Stony Brook University Medical Center in Stony Brook, New York.
Alternatively, if a patient has progressive MS, she said she would recommend discontinuing treatment if she believes the patient is being harmed by it, to focus instead on health and wellness.
Another questioner wondered what to do with a 70-year-old patient who has had no infections, has normal IgG, but insists on continuing high-efficacy B-cell therapy. Dr. Coyle responded that she would tell the patient that she believes it isn’t offering any benefit, but if the patient insisted, she would continue: “I’m not living with MS the way they are. If they tell me, ‘I believe it’s helping me and I want to stay on it,’ then so long as I don’t think I’m overtly harming them, I’m going to treat them.”
Ms. Ross agreed, and suggested that ceding to the patient’s will is an important consideration. “I think sometimes what we’re doing, if we’re not causing harm, what we’re doing is bolstering these people’s ability to continue to have hope, and that in my mind is a big part of managing their disease,” she said.
Ms. Ross has financial relationships with Alexion Pharmaceuticals, Amgen/Horizon, ArgenX, Banner, Bristol Myers Squibb, EMD Serono, Roche, Sandoz, TG Therapeutics, UCB, and Viatris. Dr. Coyle has consulted for Accordant, Amgen, Bristol Myers Squibb, EMD Serono, Genentech, GlaxoSmithKline, Horizon Therapeutics, LabCorp, Eli Lilly, Mylan, Novartis, and Sanofi Genzyme. She has received research funding from Celgene, CorEvitas, Genentech/Roche, NINDS, and Sanofi Genzyme.
