Beyond Increased Risk: Is APOE4 a Direct Cause of Alzheimer’s disease?
, a new study suggests.
More than 95% of those with two copies of the gene (APOE4 homozygotes) in a large multicohort study had higher levels of Alzheimer’s disease biomarkers by age 55 years than did those with other APOE gene variants. By age 65 years, most had developed Alzheimer’s disease symptoms and showed abnormal amyloid levels in cerebrospinal fluid and on PET.
Investigators said that such a high penetrance of Alzheimer’s disease pathology in this group suggests that APOE4 may not be just a risk factor for Alzheimer’s disease but also a distinct genetic form of the disease.
“Sometimes, we say we don’t know the cause of Alzheimer’s disease, but this would be behind 15%-20% of the population of people with Alzheimer’s disease,” lead investigator Juan Fortea, MD, PhD, director of the Memory Unit of the Neurology Department at the Hospital of Sant Pau, Barcelona, Spain, said at a press briefing.
Although some experts urge caution in interpreting these results, investigators and others say the findings, published online in Nature Medicine, could lead to calls for more widespread testing for APOE4 and may spur drug development.
High AD Penetrance
Mutations in the APP, PSEN1, and PSEN2 genes are linked to risk for early-onset autosomal-dominant Alzheimer’s disease, and dozens of other genes are associated with greater odds of late-onset disease. Among all these genes, APOE is considered the strongest genetic risk factor for late-onset Alzheimer’s disease.
Prior studies found that APOE4 homozygotes have a 60% lifetime risk for Alzheimer’s disease by age 85 years, a risk higher than that found with other gene variants or in single APOE carriers or noncarriers.
Despite that, no previous study had examined the predictability of symptom onset in APOE4 homozygotes, which make up about 2%-3% of the general population and 15-20% of those with Alzheimer’s disease. And because most biomarker studies have combined single- and double-carrier APOE4 carriers into one group, very little was known about the penetrance or disease progression in APOE4 homozygotes.
Investigators analyzed data from 3200 brain donors from the National Alzheimer’s Coordinating Center and more than 10,000 people with Alzheimer’s disease biomarkers from five multicenter cohorts in the United States and Europe.
Nearly all APOE4 homozygotes had either high or intermediate Alzheimer’s disease neuropathologic change scores compared with about 50% among APOE3 homozygotes and was the same regardless of age at time of death.
Beginning at age 55 years, APOE4 homozygotes exhibited higher levels of abnormal Alzheimer’s disease biomarkers than did APOE3 homozygotes. By age 65 years, nearly everyone with two copies of APOE4 showed abnormal levels of amyloid in cerebrospinal fluid and 75% had positive amyloid scans.
Other biomarkers showed a biologic penetrance of Alzheimer’s disease that increased with age. By age 80 years, penetrance for all amyloid and tau biomarkers reached 88%.
Postmortem analysis revealed Alzheimer’s disease and dementia symptoms were evident in APOE4 homozygotes 7-10 years before APOE3 homozygotes, with Alzheimer’s disease symptoms present at age 65 years, minor cognitive impairment at 72 years, dementia at 74 years, and death at 77 years (P <.05 differences).
When they limited analysis to only those who developed Alzheimer’s disease dementia, investigators found no difference in amyloid or tau accumulation between APOE3 and APOE4 homozygotes. That was surprising given the much earlier presentation of clinical symptoms and biomarkers in those who carried two copies of APOE4.
More Than a Risk Factor
Overall, study findings provide evidence that APOE4 homozygotes represent another form of genetically determined Alzheimer’s disease, similar to autosomal-dominant Alzheimer’s disease and down syndrome-associated Alzheimer’s disease, investigators said.
“Our work showed that APOE4 homozygotes meet the three main characteristics of genetically determined Alzheimer’s disease, namely near-full penetrance, symptom onset predictability and a predictable sequence of biomarker and clinical changes,” they wrote.
Based on the results, investigators recommend that future clinical trials avoid combining single and double APOE4 carriers into one study group.
Because the global average proportion of APOE4 homozygotes is estimated to be approximately 2%, APOE4-homozygous Alzheimer’s disease may represent one of the most frequently occurring Mendelian diseases worldwide. This could have implications for genetic counseling and genetic screening recommendations, they said.
“We may need to start treating these homozygotes as a separate group in our research so we can really understand the relation between amyloid and tau and symptoms in E4 homozygotes in a way that we have not been able to because of our practice in the field of thinking that APOE4 is this unitary risk effect,” co-investigator Sterling Johnson, PhD, professor of geriatrics and dementia, University of Wisconsin-Madison, said at a press briefing.
The findings may also have implications for Alzheimer’s disease prevention, investigators added.
“What’s particularly important is the promise that perhaps we could treat people before symptoms, particularly in people who already have the disease in their brain such as APOE4 homozygotes, which reliably predicts that they will have impairment and try to treat them beforehand,” co-investigator Reisa Sperling, MD, director of the Center for Alzheimer Research and Treatment at Brigham and Women›s Hospital and Massachusetts General Hospital, Boston, said at a press briefing.
“This is important for preventing Alzheimer’s-related dementia and a real movement forward in defining the disease on the basis of genetics and biomarkers,” she added.
Experts Offer Mixed Reactions
Commenting on the findings, Paul Mathews, MD, DPhil, group leader of the UK Dementia Research Institute Centre at Imperial College, said that the data point to a need to look at APOE4 differently.
“One implication of this work is that testing for APOE4 gene homozygosity should be assessed for use clinically, when late middle-aged people present to their doctors with symptoms of dementia,” Dr. Mathews, who was not part of the study, said in a statement.
In an accompany editorial, Yadong Huang, MD, PhD, Departments of Neurology and Pathology, University of California, San Francisco, and co-authors noted that the findings also have implications for clinical drug trials.
“So far, APOE4 homozygotes have not been treated as a separate predefined treatment group in clinical trials,” they wrote. “Following this study, APOE4 status must be recognized as a crucial parameter in trial design, patient recruitment and data analysis, with APOE4 homozygotes and heterozygotes being clearly separated. Such an approach may enhance the treatment efficacy and help tailor therapeutic interventions more effectively towards genetically defined patient populations.”
Other experts urge caution when interpreting the findings.
“It is clear that APOE4 homozygosity is tightly linked to the appearance of Alzheimer’s-related pathology, but even at age 80, 12% of people with APOE4/E4 did not have amyloid/tau biomarkers,” said Yuko Hara, PhD, director of aging and Alzheimer’s disease prevention at the Alzheimer’s Drug Discovery Foundation. “Also, having two copies of APOE4 does not mean you will definitely develop symptoms of Alzheimer’s disease in your lifetime,” Dr. Hara added.
Researchers have long known that APOE4 is a strong risk factor for Alzheimer’s disease and that people with two copies of the gene are at especially high risk, David Curtis, MD, PhD, Genetics Institute at University of College London, England, said in a statement.
“I do not see anything in this paper to justify the claim that carrying two copies of APOE4 represents some ‘distinct genetic form’ of Alzheimer’s disease,” Dr. Curtis said. “No matter how many alleles of APOE4 one carries, the underlying disease processes seem similar across cases of Alzheimer’s disease, suggesting that any effective treatment and prevention strategies, which have yet to be developed would have broad applicability.”

Consider a Four-Step Approach to Shared Decision-Making in Pediatric Dermatology
SAN DIEGO — In the clinical experience of Kelly M. Cordoro, MD, .
“SDM is a cornerstone of person-centered care,” Dr. Cordoro, professor of dermatology and pediatrics at the University of California, San Francisco, said at the Society for Pediatric Dermatology meeting, held in advance of the annual meeting of the American Academy of Dermatology. “We do it all the time. It can be patient-led, clinician-led, or a patient/family dyad approach. If we do it well, it can improve outcomes. Patients report more satisfying interactions with their care team. It brings adolescent patients especially a sense of independence and they adapt faster to their illness.”
Conditions such as acne, psoriasis, and atopic dermatitis have multiple treatment options, often without a single best choice. The ideal treatment depends on disease characteristics (extent, sites affected, symptoms, and natural history), the patient (age, comorbidities, overall disease burden), therapies (safety, efficacy, duration, and adverse events), and preferences (logistics, time, shots vs. pills, etc.). “These factors vary between patients and within the same patient over time, and at each step along the course of the condition, SDM approaches are relevant,” she said.
AHRQ’s Five-Step Approach
The Agency for Healthcare Research and Quality developed a five-step approach to SDM known as SHARE: Seek your patient’s participation; Help your patient explore and compare treatment options; Assess your patient’s values and preferences; Reach a decision with your patient, and Evaluate your patient’s decision. “We do this all the time in practice with adult patients, but may not label it as SDM,” said Dr. Cordoro, chief and fellowship director of pediatric dermatology at UCSF.
“Where it gets a little murkier is in pediatric decision-making, which is a complex type of surrogate decision-making.” In this situation the patient — a minor — does not have full autonomy. The challenge for caregivers is that giving or withholding permission for interventions is a difficult role. “Their job is to protect the patient’s well-being while empowering them toward independence,” she said. “It can be hard for caregivers to understand complex information.” The challenge for clinicians, she continued, is to know when to invite SDM. This requires relational and sharp communication skills. “We must consider our patient’s/family’s health literacy and be sure the information we share is understood,” she said. “What are the social and structural determinants of health that are going to influence decision-making? You want to move into a relationship like this with cultural humility so you can understand what their preferences are and how they’re seeing the problem. Because there’s no universal agreement on the age at which minors should be deemed decision-making competent in health care, the approach is nuanced and depends on each individual patient and family.”
Dr. Cordoro proposed the following four-step approach to SDM to use in pediatric dermatology:
Step 1: Share relevant information about the condition and treatment options in a clear and understandable manner. The average US resident is at the seventh-to eighth-grade level, “so we have to avoid medical jargon and use plain language,” Dr. Cordoro said. Then, use the teach-back approach to assess their understanding. “Ask, ‘What is your understanding of the most important points that we talked about?’ Or, ‘Please share with me what you heard so I’m sure we all understand the plan.’ Using these techniques will reduce the barriers to care such as health literacy.”
Step 2: Solicit and understand patient/patient family perspectives, preferences and priorities. The goal here is to uncover their beliefs, concerns, and assumptions that may influence their decisions. “Be mindful of power asymmetry,” she noted. “Many families still believe the doctor is the boss and they are there to be told what to do. Be clear that the patient has a say. Talk directly to the patient about their interests if developmentally appropriate.”
Step 3: Invite patients/family into a shared decision-making conversation. Consider statements like, “There are many reasonable options here. Let’s work together to come up with the decision that’s right for you.” Or, “Let’s start by exploring your specific goals and concerns. As you think about the options I just talked to you about, what’s important to you?” Or, “Do you want to think about this decision with anyone else?”
Step 4: Check back in frequently. Pause between significant points and check in. “See how they’re doing during the conversation,” she said. “At future appointments, remember to solicit their input on additional decisions.”
In Dr. Cordoro’s opinion, one potential pitfall of SDM is an over-reliance on patient decision aids. “Very few are available in dermatology,” she said. “Some are relevant but none specifically to pediatric dermatology. They are often complex and require a high reading comprehension level. This disadvantages patients and families with low health literacy. Keep it clear and simple. Your patients will appreciate it.”
Dr. Cordoro reported having no relevant disclosures.

The goal here is to uncover their beliefs, concerns, and assumptions that may influence their decisions. “Be mindful of power asymmetry,” she noted. “Many families still believe the doctor is the boss and they are there to be told what to do. Be clear that the patient has a say. Talk directly to the patient about their interests if developmentally appropriate.”
Step 3: Invite patients/family into a shared decision-making conversation. Consider statements like, “There are many reasonable options here. Let’s work together to come up with the decision that’s right for you.” Or, “Let’s start by exploring your specific goals and concerns. As you think about the options I just talked to you about, what’s important to you?” Or, “Do you want to think about this decision with anyone else?”
Step 4: Check back in frequently. Pause between significant points and check in. “See how they’re doing during the conversation,” she said. “At future appointments, remember to solicit their input on additional decisions.”
In Dr. Cordoro’s opinion, one potential pitfall of SDM is an over-reliance on patient decision aids. “Very few are available in dermatology,” she said. “Some are relevant but none specifically to pediatric dermatology. They are often complex and require a high reading comprehension level. This disadvantages patients and families with low health literacy. Keep it clear and simple. Your patients will appreciate it.”

SAN DIEGO — In the clinical experience of Kelly M. Cordoro, MD, .
“SDM is a cornerstone of person-centered care,” Dr. Cordoro, professor of dermatology and pediatrics at the University of California, San Francisco, said at the Society for Pediatric Dermatology meeting, held in advance of the annual meeting of the American Academy of Dermatology. “We do it all the time. It can be patient-led, clinician-led, or a patient/family dyad approach. If we do it well, it can improve outcomes. Patients report more satisfying interactions with their care team. It brings adolescent patients especially a sense of independence and they adapt faster to their illness.”
Conditions such as acne, psoriasis, and atopic dermatitis have multiple treatment options, often without a single best choice. The ideal treatment depends on disease characteristics (extent, sites affected, symptoms, and natural history), the patient (age, comorbidities, overall disease burden), therapies (safety, efficacy, duration, and adverse events), and preferences (logistics, time, shots vs. pills, etc.). “These factors vary between patients and within the same patient over time, and at each step along the course of the condition, SDM approaches are relevant,” she said.
AHRQ’s Five-Step Approach
The Agency for Healthcare Research and Quality developed a five-step approach to SDM known as SHARE: Seek your patient’s participation; Help your patient explore and compare treatment options; Assess your patient’s values and preferences; Reach a decision with your patient, and Evaluate your patient’s decision. “We do this all the time in practice with adult patients, but may not label it as SDM,” said Dr. Cordoro, chief and fellowship director of pediatric dermatology at UCSF.
“Where it gets a little murkier is in pediatric decision-making, which is a complex type of surrogate decision-making.” In this situation the patient — a minor — does not have full autonomy. The challenge for caregivers is that giving or withholding permission for interventions is a difficult role. “Their job is to protect the patient’s well-being while empowering them toward independence,” she said. “It can be hard for caregivers to understand complex information.” The challenge for clinicians, she continued, is to know when to invite SDM. This requires relational and sharp communication skills. “We must consider our patient’s/family’s health literacy and be sure the information we share is understood,” she said. “What are the social and structural determinants of health that are going to influence decision-making? You want to move into a relationship like this with cultural humility so you can understand what their preferences are and how they’re seeing the problem. Because there’s no universal agreement on the age at which minors should be deemed decision-making competent in health care, the approach is nuanced and depends on each individual patient and family.”
Dr. Cordoro proposed the following four-step approach to SDM to use in pediatric dermatology:
Step 1: Share relevant information about the condition and treatment options in a clear and understandable manner. The average US resident is at the seventh-to eighth-grade level, “so we have to avoid medical jargon and use plain language,” Dr. Cordoro said. Then, use the teach-back approach to assess their understanding. “Ask, ‘What is your understanding of the most important points that we talked about?’ Or, ‘Please share with me what you heard so I’m sure we all understand the plan.’ Using these techniques will reduce the barriers to care such as health literacy.”
Step 2: Solicit and understand patient/patient family perspectives, preferences and priorities. The goal here is to uncover their beliefs, concerns, and assumptions that may influence their decisions. “Be mindful of power asymmetry,” she noted. “Many families still believe the doctor is the boss and they are there to be told what to do. Be clear that the patient has a say. Talk directly to the patient about their interests if developmentally appropriate.”
Step 3: Invite patients/family into a shared decision-making conversation. Consider statements like, “There are many reasonable options here. Let’s work together to come up with the decision that’s right for you.” Or, “Let’s start by exploring your specific goals and concerns.

High Olive Oil Intake Linked to Lower Dementia-Related Death
, a new study suggested.
Data from a prospective study of more than 92,000 people showed consuming at least 7 g of olive oil a day — about half a tablespoon — was associated with a 28% lower risk for dementia-related death.
Replacing one teaspoon of margarine and mayonnaise with the equivalent amount of olive oil was associated with an 8%-14% lower risk for dementia-related mortality.
“Opting for olive oil, a natural product, instead of more processed fats such as margarine and mayonnaise, is a safe choice and may reduce risk of fatal dementia,” said lead investigator Anne-Julie Tessier, RD, PhD, research associate, Department of Nutrition, Harvard T.H. Chan School of Public Health, Boston.
However, “intervention studies are needed to confirm causal effect and optimal quantity of olive oil intake,” she added.
The study was published online in JAMA Network Open.
A Spoonful of Olive Oil
A growing body of evidence has shown a link between the Mediterranean diet and preserved cognitive function and lower risk for cardiovascular disease (CVD). But its association with dementia mortality was unknown.
Investigators analyzed data on over 92,000 participants (66% women; mean age, 56 years) in the Nurses’ Health Study (NHS) and Health Professionals Follow-Up Study (HPFS) who were free of CVD and cancer at baseline.
Both studies were conducted between 1990 and 2018, with olive oil intake assessed every 4 years using a food frequency questionnaire. Dementia-related mortality was ascertained from death records.
The researchers also evaluated the joint association of diet quality (particularly adherence to the Mediterranean diet and Alternative Healthy Eating Index score) and olive oil consumption with the risk for dementia-related mortality. And they estimated the difference in the risk for dementia-related mortality when other dietary fats were substituted with an equivalent amount of olive oil.
There were 4751 dementia-related deaths during the 28-year follow-up period. People with two copies of the apolipoprotein epsilon-4 (APOE epsilon-4) allele — a known risk factor for Alzheimer’s disease — had a fivefold to ninefold greater likelihood of dementia-related death.
Compared with no or rare olive oil intake, consumption of 7 g of olive oil or more per day was associated with a 28% lower risk for dementia-related mortality (adjusted hazard ratio [HR], 0.72; P < .001), after adjusting for lifestyle and socioeconomic factors. The finding remained consistent even with further adjustment for the APOE epsilon-4 allele.
Each 5-g increment in olive oil consumption had an inverse association with dementia-related death in women (HR, 0.88; 95% CI, 0.84-0.93) but not in men (HR, 0.96; 95% CI, 0.88-1.04).
No interaction by diet quality scores was found.
No Link With Diet Quality
“Typically, people who use olive oil for cooking or as a dressing have an overall better quality of their diet, but interestingly, we found the association between more olive oil and reduced risk of dementia-related death to be regardless of this factor,” Dr. Tessier said.
Replacing 5 g per day of margarine and mayonnaise with the equivalent amount of olive oil was associated with an 8%-14% lower risk for dementia mortality. Substitutions for other vegetable oils or butter were not significant.
“Some antioxidant compounds in olive oil can cross the blood-brain barrier, potentially having a direct effect on the brain,” Dr. Tessier said. “It is also possible that olive oil has an indirect effect on brain health by benefiting cardiovascular health.”
The authors noted several study limitations, including the possibility of reverse causation, due to the observational nature of the study.
It is also plausible that higher olive oil intake could be indicative of a healthier diet and higher socioeconomic status, although the results remained consistent after accounting these factors, the authors noted.
The study population included only healthcare professionals and was primarily non-Hispanic White people, which could limit generalizability.
Causality Versus Connection
Commenting on the findings, Rebecca M. Edelmayer, PhD, senior director of scientific engagement for the Alzheimer’s Association, cautioned that the study was designed to show correlation, not causation.
Other notable limitations include measuring prevalence or incidence of dementia from death records because dementia and Alzheimer’s disease are often underreported as a cause of death.
Moreover, people in the highest olive oil consumption group also had better diet quality, higher alcohol intake, were more physically active, and less likely to smoke, Dr. Edelmayer said.
“All of these factors may have an impact on risk of cognitive decline and dementia, separately from or in addition to olive oil consumption,” said Dr. Edelmayer, who was not involved with the study.
She echoed the authors’ concerns that the study was conducted in predominantly non-Hispanic White people and noted that the protective benefits of olive oil were no longer statistically significant for men after adjusting for potential confounders.
It “would be wonderful if a particular food could delay or prevent Alzheimer’s disease, but we do not have scientific evidence that these claims are true,” Dr. Edelmayer said. “We need randomized controlled clinical trials to evaluate whether any foods have a scientifically proven beneficial effect.”

Do Patients Benefit from Cancer Trial Participation?
TOPLINE:
METHODOLOGY:
- The view that patients with cancer benefit from access to investigational drugs in the clinical trial setting is widely held but does necessarily align with trial findings, which often show limited evidence of a clinical benefit. First, most investigational treatments assessed in clinical trials fail to gain regulatory approval, and the minority that are approved tend to offer minimal clinical benefit, experts explained.
- To estimate the survival benefit and toxicities associated with receiving experimental treatments, researchers conducted a meta-analysis of 128 trials comprising 141 comparisons of an investigational drug and a control treatment, which included immunotherapies and targeted therapies.
- The analysis included 42 trials in non–small cell lung cancer (NSCLC), 37 in breast cancer, 15 in hepatobiliary cancer, 13 in pancreatic cancer, 12 in colorectal cancer, and 10 in prostate cancer, involving a total of 47,050 patients.
- The primary outcome was PFS and secondary outcomes were overall survival and grades 3-5 serious adverse events.
TAKEAWAY:
- Overall, the experimental treatment was associated with a 20% improvement in PFS (pooled hazard ratio [HR], 0.80), corresponding to a median 1.25-month PFS advantage. The PFS benefit was seen across all cancer types, except pancreatic cancer.
- Overall survival improved by 8% with experimental agents (HR, 0.92), corresponding to 1.18 additional months. A significant overall survival benefit was seen across NSCLC, breast cancer, and hepatobiliary cancer trials but not pancreatic, prostate, colorectal cancer trials.
- Patients in the experimental intervention group, however, experienced much higher risk for grade 3-5 serious adverse events (risk ratio [RR], 1.27), corresponding to 7.40% increase in absolute risk. The greater risk for serious adverse events was significant for all indications except prostate cancer (RR, 1.13; 95% CI, 0.91-1.40).
IN PRACTICE:
“We believe our findings are best interpreted as suggesting that access to experimental interventions that have not yet received full FDA approval is associated with a marginal but nonzero clinical benefit,” the authors wrote.
“Although our findings seem to reflect poorly on trials as a vehicle for extending survival for participants, they have reassuring implications for clinical investigators, policymakers, and institutional review boards,” the researchers said, explaining that this “scenario allows clinical trials to continue to pursue promising new treatments — supporting incremental advances that sum to large gains over extended periods of research — without disadvantaging patients in comparator groups.”
SOURCE:
Renata Iskander, MSc, of McGill University, Montreal, Quebec, Canada, led this work, which was published online on April 29, 2024, in Annals of Internal Medicine.
LIMITATIONS:
There was high heterogeneity across studies due to variations in drugs tested, comparators used, and populations involved. The use of comparators below standard care could have inflated survival benefits. Additionally, data collected from ClinicalTrials.gov might be biased due to some trials not being reported.

Multiple Sclerosis Highlights From AAN 2024
The latest research on therapeutic management of patients with relapsing-remitting multiple sclerosis (RRMS) presented at the American Academy of Neurology (AAN) 2024 annual meeting is reported by Dr Pavan Bhargava from the Johns Hopkins University School of Medicine in Baltimore, Maryland.
Dr Bhargava first discusses a small study out of Germany exploring child development after exposure to monoclonal antibodies (mAbs) during breastfeeding. Currently, most mAbs are not approved for use during lactation. However, researchers found that infants studied for up to 36 months showed no evidence of adverse development or health effects compared with controls.
Next, Dr Bhargava discusses a trial examining pregnancy and infant outcomes in patients receiving ocrelizumab. They analyzed registry data of 3000 pregnancies and determined that in-utero exposure to ocrelizumab was not associated with an increased risk for adverse outcomes.
He then details a small, single-center cohort study evaluating the infection rates associated with anti-CD20 use in pediatric-onset RRMS. The study reported that approximately one third of participants experienced moderate to severe infections over 5 years of follow-up.
Finally, Dr Bhargava highlights the CHIMES trial, a 1-year analysis of efficacy and safety data from Black and Hispanic persons with RRMS who received ocrelizumab. Researchers found that the overall efficacy and safety results were similar to prior ocrelizumab clinical trials.

Dr Bhargava first discusses a small study out of Germany exploring child development after exposure to monoclonal antibodies (mAbs) during breastfeeding. Currently, most mAbs are not approved for use during lactation. However, researchers found that infants studied for up to 36 months showed no evidence of adverse development or health effects compared with controls.
Next, Dr Bhargava discusses a trial examining pregnancy and infant outcomes in patients receiving ocrelizumab. They analyzed registry data of 3000 pregnancies and determined that in-utero exposure to ocrelizumab was not associated with an increased risk for adverse outcomes.
He then details a small, single-center cohort study evaluating the infection rates associated with anti-CD20 use in pediatric-onset RRMS. The study reported that approximately one third of participants experienced moderate to severe infections over 5 years of follow-up.
Finally, Dr Bhargava highlights the CHIMES trial, a 1-year analysis of efficacy and safety data from Black and Hispanic persons with RRMS who received ocrelizumab. Researchers found that the overall efficacy and safety results were similar to prior ocrelizumab clinical trials.

Progressive Multiple Sclerosis Highlights From AAN 2024
Biomarkers indicating worsening of progressive multiple sclerosis (MS) can inform decisions about treatment, and two studies presented at the 2024 American Academy of Neurology meeting show promise in this area.
Dr Patricia Coyle of Stony Brook University Hospital in Stony Brook, New York, discusses a study showing that stool glial fibrillary acidic protein (GFAP) was markedly increased in patients with progressive MS vs those with relapsing-remitting disease or healthy controls.
A separate study using brain and cervical spine MRI showed that cervical spine gray matter atrophy, particularly at C2-3, strongly correlated with disability markers in patients with progressive MS.
Dr Coyle closes by outlining a small but important study showing that nasal foralumab dampened microglial activation and stabilized clinical progression in patients with progressive MS.

Myasthenia Gravis Highlights From AAN 2024
Highlights of the latest research on therapeutic management of patients with myasthenia gravis (MG) presented at the American Academy of Neurology (AAN) 2024 annual meeting are discussed by Dr Richard Nowak of Yale University, New Haven, Connecticut.
Dr Nowak first discusses LUMINESCE, a phase 3, randomized, double-blind study assessing the efficacy and safety of satralizumab, a humanized interleukin-6 receptor monoclonal recycling antibody. In this trial with 188 participants, satralizumab provided a statistically relevant, though modest, improvement in the Myasthenia Gravis Activities of Daily Living score.
Next, Dr Nowak details part A of ADAPT NXT, comparing a fixed- cycle dosing vs every-other-week dosing of intravenous efgartigimod. The researchers found that efgartigimod was well tolerated regardless of the regimen used, offering a way to individualize treatment for patients with MG.
He then discusses the CHAMPION MG open-label extension trial, which examined the long-term efficacy and safety of ravulizumab in adults with anti-acetylcholine receptor antibody–positive generalized MG. The final analysis demonstrated the drug's durable efficacy through 164 weeks in this patient population.
Finally, Dr Nowak reports on a small trial using retrospective data determining the effectiveness of eculizumab treatment by start time. The study found that early eculizumab initiation in the first 2 years of diagnosis may offer greater clinical benefit compared with later initiation.

OTC Solution for Erectile Dysfunction?
Up to 60% of men with erectile dysfunction who were not candidates for phosphodiesterase 5 (PDE5) inhibitors achieved erections in less than 10 minutes after a single application of a first-on-the-market nonprescription gel to the glans, a new study found.
Wayne Hellstrom, MD, chief of andrology at Tulane School of Medicine in New Orleans, who presented the study of MED3000 [Eroxon] on May 5 at the 2024 annual meeting of the American Urological Association in San Antonio, Texas, said that the gel is considered to be a device by the US Food and Drug Administration (FDA). The agency approved the product in June 2023.
A spokesman for Futura, which makes MED3000, said that the gel will be on the market 2025. No price for the United States has been announced, but a four-pack of single-use tubes sells for the equivalent of roughly $31 in the United Kingdom.
Dr. Hellstrom, a former adviser to Futura, he said he expects MED3000 will be “a potential first-line therapy in addition to PDE5 inhibitors,” which are vasodilating drugs that stimulate the corpora cavernosa of the penis, facilitating erection with sexual stimulation.
He noted that PDE5s are contraindicated for many men; are not tolerated in others; are not completely effective; or work too slowly, taking 1-2 hours to work. As a result, up to 50% of patients cease using a PDE5 inhibitor within 1 year, he said.
Futura said the gel contains a combination of volatile solvents which, when applied to the head of the penis, evaporate rapidly, stimulating nerve endings through an initial cooling effect followed by a warming sensation. This reaction releases nitric oxide, relaxing the smooth muscle tissue inside the penis and increasing blood flow that is needed to obtain an erection.
Dr. Hellstrom noted that MED3000 is noninvasive and causes no side effects and is slightly more effective if applied by a partner.
The new findings come from two studies of 250 men with erectile dysfunction (FM57) who used MED3000 over 12 weeks and a randomly assigned arm (FM71) with two groups of 48 men who used either MED3000 or 5 mg of tadalafil over 24 weeks.
Erections were achieved in less than 10 minutes in 60.1% of men in the FM57 group and 44.9% of those in the FM71 group.
Overall, less than 2% of the men who usedMED3000 and 4% of those who took tadalafil reported adverse effects. These events included headaches in 3% of the combined MED3000 group and 19.1% of the tadalafil group. Roughly 1% of men who used MED3000 reported penile burning sensation compared with none in the group taking tadalafil.
Problematic Design?
Kevin McVary, MD, a professor of urology at Stritch School of Medicine of Loyola University, outside of Chicago, and director of the Center for Male Health, criticized the study design and added that he did not believe MED3000 had been proven beneficial.
“Are they expecting the Cialis 5 mg to work within 10 minutes? Because it doesn’t,” Dr. McVary said. “It doesn’t get absorbed into the bloodstream for about 2.5 hours.”
Dr. McVary said that men with erectile dysfunction will probably do anything to avoid seeing a physician about the condition, which could make MED3000 highly marketable.
However, he said, examinations would be important to detect unrecognized underlying cardiac disease, especially in younger men. “ED can function as the classic canary in a coal mine where it tells you who’s at risk for unexpected early death,” he said.
Dr. Hellstrom is a former adviser to Futura Medical Developments, which funded the research. Dr. McVary reported no relevant financial conflicts of interest.

From Pharma’s Factories Direct to You
Pharmaceutical giant Eli Lilly recently announced that its newly approved weight loss medication Zepbound — a glucagon-like peptide 1 receptor agonist (GLP-1 RA) akin to Mounjaro, Ozempic, and Wegovy — will be prescribed by independent telehealth providers on a platform managed by the company itself. The drug can be subsequently shipped direct to consumer (DTC), allowing delivery straight to patients’ homes.
This arrangement raises serious concerns about an inherent conflict of interest, as we previously discussed. What happens when a pharmaceutical company influences access to remote providers who prescribe the very medications it manufactures?
Without new guardrails, the potential for misleading messaging to result in dangerous prescribing patterns looms large. The United States is one of only two countries to allow DTC advertising of prescription drugs, and the explosion in demand for GLP-1 RAs is partly attributable to this model (Oh, oh, Ozempic, anyone?). Americans spent over $78 billion on weight loss goods and services in 2019; time-intensive approaches such as diet and exercise are understandably difficult, and the public has always looked for a magic cure. Although GLP-1 RAs are promising, they may present a path to disaster without proper supervision.
LillyDirect, which in addition to Zepbound offers migraine medications and other products in the company’s catalogue, primarily aims to increase access to medication and reduce costs of the drugs for consumers. The stated mission is noble: By cutting out the middlemen of traditional pharmacies and benefit managers, administrative costs drop. LillyDirect goes a step further by reducing the need for patients to visit their regular family doctor to receive these medications.
On the surface, this design appears promising. Wait times for doctor’s appointments will fall. Patients can order drugs from the comfort of their home. Everyone benefits. Or do they?
Although easier access and reduced cost may be an apparent win for patients, DTC arrangements complicate the ethics of prescriptions and patient follow-up. This model reminds us of the roots of the opioid crisis, where powerful advertising and relationships between prescribers and drugmakers led to great harm. Providers often faced a conflict of interest when prescribing dangerous drugs to patients who requested them. We must learn from these mistakes to ensure there is critical oversight into the independence of prescribers used by LillyDirect and other DTC platforms.
Adding to these parallels, once a patient begins a GLP-1 medication such as Zepbound, stopping treatment will probably lead to regaining lost weight, serving as negative reinforcement. Hence, patients may decide never to discontinue these medications.
Obtaining what amounts to a lifelong prescription from a telehealth provider who may never follow a patient sets a dangerous precedent that will be difficult to unravel once begun. Recent challenges in access to medications such as Zepbound have been complicated by supply chain and manufacturing issues, leading to potential interruptions in patient access, ultimately affecting compliance. The rapid increase in online providers indicates competition for distribution channels has sharply increased and poses a threat to Lilly’s DTC site.
Furthermore, the lack of a regular physician to monitor patients introduces uncertainty in safety and continuity of care. These are important tenets in protecting patients, especially patients who are not diabetic and desire a quick fix. We have already seen a huge, arguably unrestrained, rise in prescriptions of GLP-1 RAs for weight loss — up to a 352% increase in 2023.
These drugs have shown great promise and are generally safe when used in the right patient, but important contraindications exist — namely, serious gastrointestinal side effects and low blood glucose in nondiabetic persons — that an astute physician must consider. Patients desiring these medications often must undergo comprehensive laboratory testing and cardiac evaluation, both before initiation and during regular follow-up, to check for comorbidities.
The American College of Physicians cautioned against such prescribing practices in a recent position statement, emphasizing that the lack of an established care provider could adversely affect patients. We note that the potential harms of DTC sales would concentrate in economically and racially underserved communities, where obesity, lack of insurance, and low health literacy are more common.
But the DTC genie is out of the pill bottle, and as such platforms become more common, patients will inherently take more ownership over their medical care. Remote providers will of course not be following these patients and evaluating for side effects. As a result, we in medical practice must be abreast of new downsides of these medications if and when they arise.
Every clinician must be aware of the medications a patient is taking, even those that they did not prescribe. They should educate their patients about drug-drug interactions and side effects and order lab tests to monitor for side effects.
Independent physicians abide by an underlying oath: First, do no harm. They serve as a trusted check on industry and a valuable long-term partner for patients. Where are the guardrails to protect patients and ensure that pharmaceutical companies are not essentially pushing prescriptions for their own products? Will traditional healthcare providers be effectively relegated to a bystander role in Lilly’s transactional approach to medication distribution? Unlike other commercial goods, pharmacologics have great nuance; not every approved medication is meant for every patient.

The drug can be subsequently shipped direct to consumer (DTC), allowing delivery straight to patients’ homes.
This arrangement raises serious concerns about an inherent conflict of interest, as we previously discussed. What happens when a pharmaceutical company influences access to remote providers who prescribe the very medications it manufactures?
Without new guardrails, the potential for misleading messaging to result in dangerous prescribing patterns looms large. The United States is one of only two countries to allow DTC advertising of prescription drugs, and the explosion in demand for GLP-1 RAs is partly attributable to this model (Oh, oh, Ozempic, anyone?). Americans spent over $78 billion on weight loss goods and services in 2019; time-intensive approaches such as diet and exercise are understandably difficult, and the public has always looked for a magic cure. Although GLP-1 RAs are promising, they may present a path to disaster without proper supervision.
LillyDirect, which in addition to Zepbound offers migraine medications and other products in the company’s catalogue, primarily aims to increase access to medication and reduce costs of the drugs for consumers. The stated mission is noble: By cutting out the middlemen of traditional pharmacies and benefit managers, administrative costs drop. LillyDirect goes a step further by reducing the need for patients to visit their regular family doctor to receive these medications.
On the surface, this design appears promising. Wait times for doctor’s appointments will fall. Patients can order drugs from the comfort of their home. Everyone benefits. Or do they?
Although easier access and reduced cost may be an apparent win for patients, DTC arrangements complicate the ethics of prescriptions and patient follow-up. This model reminds us of the roots of the opioid crisis, where powerful advertising and relationships between prescribers and drugmakers led to great harm. Providers often faced a conflict of interest when prescribing dangerous drugs to patients who requested them. We must learn from these mistakes to ensure there is critical oversight into the independence of prescribers used by LillyDirect and other DTC platforms.
Adding to these parallels, once a patient begins a GLP-1 medication such as Zepbound, stopping treatment will probably lead to regaining lost weight, serving as negative reinforcement. Hence, patients may decide never to discontinue these medications.
Obtaining what amounts to a lifelong prescription from a telehealth provider who may never follow a patient sets a dangerous precedent that will be difficult to unravel once begun. Recent challenges in access to medications such as Zepbound have been complicated by supply chain and manufacturing issues, leading to potential interruptions in patient access, ultimately affecting compliance. The rapid increase in online providers indicates competition for distribution channels has sharply increased and poses a threat to Lilly’s DTC site.
Furthermore, the lack of a regular physician to monitor patients introduces uncertainty in safety and continuity of care. These are important tenets in protecting patients, especially patients who are not diabetic and desire a quick fix. We have already seen a huge, arguably unrestrained, rise in prescriptions of GLP-1 RAs for weight loss — up to a 352% increase in 2023.
These drugs have shown great promise and are generally safe when used in the right patient, but important contraindications exist — namely, serious gastrointestinal side effects and low blood glucose in nondiabetic persons — that an astute physician must consider. Patients desiring these medications often must undergo comprehensive laboratory testing and cardiac evaluation, both before initiation and during regular follow-up, to check for comorbidities.
The American College of Physicians cautioned against such prescribing practices in a recent position statement, emphasizing that the lack of an established care provider could adversely affect patients. We note that the potential harms of DTC sales would concentrate in economically and racially underserved communities, where obesity, lack of insurance, and low health literacy are more common.
But the DTC genie is out of the pill bottle, and as such platforms become more common, patients will inherently take more ownership over their medical care. Remote providers will of course not be following these patients and evaluating for side effects. As a result, we in medical practice must be abreast of new downsides of these medications if and when they arise.
Every clinician must be aware of the medications a patient is taking, even those that they did not prescribe. They should educate their patients about drug-drug interactions and side effects and order lab tests to monitor for side effects.
Independent physicians abide by an underlying oath: First, do no harm. They serve as a trusted check on industry and a valuable long-term partner for patients. Where are the guardrails to protect patients and ensure that pharmaceutical companies are not essentially pushing prescriptions for their own products? Will traditional healthcare providers be effectively relegated to a bystander role in Lilly’s transactional approach to medication distribution? Unlike other commercial goods, pharmacologics have great nuance; not every approved medication is meant for every patient.

Knee Osteoarthritis Trials Show Promising Results for Several Novel Injectables
VIENNA — Encouraging primary or secondary analyses of trial data for the use of several novel injectables and gene therapy for knee osteoarthritis (OA) were reported at the OARSI 2024 World Congress.
Of all the approaches discussed during the News in Therapies session at OARSI 2024, the most intriguing was the use of the placental extract PTP-001 (MOTYS, Bioventus), session chair Nancy E. Lane, MD, of the University of California Davis School of Medicine, Sacramento, California, told this news organization.
Other notable presentations of data from trials of investigational agents for knee OA included an update from the SPRINGBOARD phase 2B trial of EP-104IAR, a novel long-acting formulation of the corticosteroid fluticasone propionate; a phase 2 trial of pentosan polysulfate sodium (PPS), a non-opioid, semi-synthetic xylose-based polysaccharide; and an update on phase 2 study results for XT-150, a non-viral, plasmid-based gene therapy designed to express a proprietary variant of interleukin 10 (IL-10).
PTP-001 (MOTYS)
Indeed, promising results were seen in a phase 2 trial testing a single intra-articular (IA) injection of PTP-001 vs an IA saline placebo in just over 200 individuals with symptomatic knee OA. Results of this dose-finding study were presented by Alessandra Pavesio, senior vice president and the chief science officer of Bioventus/Doron Therapeutics, Durham, North Carolina.
Ms. Pavesio reported there were decreases in knee pain and improvements in knee function, as measured using the Western Ontario and McMaster Universities Arthritis Index (WOMAC). These changes were seen after 26 weeks of treatment with PTP-001 given at either a low (100 mg, n = 74) or high (200 mg, n = 40) dose.
Although the changes were only numerically and not statistically different from placebo (n = 71) when looking at the total study population, Ms. Pavesio noted that a key objective of the trial had been to identify populations of patients that may benefit.
When they looked at the effects of PTP-001 solely in those with unilateral knee OA, WOMAC pain scores were decreased to a significantly greater extent with both the high and low doses of PTP-001 vs placebo. Decreases in the least squares mean (LSM) change in WOMAC pain from baseline to week 26 were 26.8 with 100-mg PTP-001, 36.1 with 200-mg PTP-001, and 24.0 with placebo (P = .072). A similarly greater effect for PTP-001 was also seen for LSM change in WOMAC function (26.4, 36.0, and 20.0, respectively; P = .023).
Ms. Pavesio noted that the only real side effect seen during the trial was an initial inflammatory reaction within the first 2 days of IA injection, which resolved within a few days without further problems.
The results are promising enough for Ms. Pavesio and her team to consider a phase 3 trial.
Dr. Lane asked Ms. Pavesio: “So, what’s in the secret sauce? You said it was ground-up placentas?” To which Ms. Pavesio replied that it contained about 300 different molecules which came from amnion, chorion, and umbilical cord tissue obtained from consented placental donation.
Dr. Lane subsequently told this news organization: “It’s probably a bunch of growth factors and cytokines, but if it’s not toxic, and they can standardize it, then it might be good. We remain open minded because we haven’t figured it out.”
Novel Fluticasone Delivery
In the same session, James A. Helliwell, MD, cofounder, director, and chief executive officer of Eupraxia Pharmaceuticals in Victoria, British Columbia, Canada, presented updated data from the SPRINGBOARD phase 2B trial of EP-104IAR, a novel long-acting formulation of the corticosteroid fluticasone propionate.
Dr. Helliwell, a cardiothoracic anesthesiologist, explained that EP-104IAR uses proprietary technology to form fluticasone into a crystal that can then be injected directly into the joint. This then slowly diffuses out to provide a highly localized treatment.
The SPRINGBOARD trial recruited just over 300 individuals with moderate knee OA and moderate to severe WOMAC pain and randomly allocated 164 to a single IA injection of EP-104IAR and 164 to a matching vehicle injection as a placebo. The latter was a slightly viscous substance that behaved like hyaluronic acid, Dr. Helliwell said.
The LSM change in total WOMAC score from baseline to week 12 showed a greater improvement with EP-104IAR than with placebo in a per protocol analysis (−2.79 vs −2.07; P = .002). Similar results were seen for the WOMAC subscales of pain (−2.97 vs −2.24; P = .003), function (−2.64 vs −1.99; P = .005), and stiffness (−2.85 vs −2.05; P = .001).
These differences persisted, Dr. Helliwell reported, out to a 20-week assessment for total WOMAC score, function, and stiffness and out to a 15-week assessment for WOMAC pain.
It’s probably no surprise that a steroid works, Dr. Helliwell said, noting that the safety profile of EP-104IAR may be better than that of regular IA steroid injection because it has “few off-target” effects. He reported that there were “minimal, clinically insignificant, and transient effects” of EP-104IAR on serum cortisol. There was no effect on glucose metabolism, even in patients with diabetes, he said.
“There is a group of our patients that we give long-acting steroids to in the joint, so it looked like [the EP-104IAR] safety profile was really good,” Dr. Lane told this news organization. However, she added: “I’m worried about the price tag associated with it.”
PPS
Although it perhaps can’t be described as a novel injectable per se, Mukesh Ahuja, MBBS, global clinical head of osteoarthritis at Paradigm Biopharmaceuticals, presented results of the novel use of PPS.
“PPS is a non-opioid, semi-synthetic xylose-based polysaccharide that is derived from beechwood trees,” Dr. Ahuja said. “It has a long-track record for treating pain, inflammation, and thrombosis in humans.”
There are currently two approved formulations: Oral capsules used for the treatment of interstitial cystitis in the European Union, United States, and Australia and an injectable form used in Italy for thromboprophylaxis.
Dr. Ahuja presented data from a phase 2 trial that looked at the effect of once- or twice-weekly subcutaneous injections of PPS vs placebo in 61 people with knee OA pain. Assessments were made after 56, 168, and 365 days of treatment.
Results showed PPS injections resulted in significant improvements in total WOMAC score, WOMAC pain, and WOMAC function, with more PPS- than placebo-treated individuals achieving and then maintaining at least a 30% or greater improvement in pain and a 56% improvement in function.
Rescue medication use was lower in the PPS-treated patients, and Patient Global Impression of Change were significantly higher, Dr. Ahuja said.
Exploratory analyses of synovial fluid biomarkers showed PPS could be having a direct inflammatory effect, with reductions in several proinflammatory cytokines, such as IL-6 and tumor necrosis factor alpha.
An assessment of OA disease progression using MRI analysis suggested that there may be an effect on cartilage thickness and volume, as well as bone marrow lesions and overall joint inflammation.
Gene Therapy
Elsewhere at OARSI 2024, updated data were reported on XT-150, a non-viral, plasmid-based gene therapy designed to express a proprietary variant (v) of IL-10.
Howard Rutman, MD, MBA, chief medical officer of Xalud Therapeutics, reported data from a patient subgroup analysis of a phase 2 trial, which evaluated the effects of single and repeat IA injections of XT-150.
Previously, it was found that a single dose of XT-150 (0.15 mg/mL or 0.45 mg/mL) given as a 1-mL IA injection did not meet its primary endpoint of a greater proportion of patients achieving a 30% or more improvement in WOMAC pain at 180 days vs a matching placebo.
However, it was noted that 17% of the patients in the trial had a baseline WOMAC pain score of less than 8, so the new analysis focused on a modified intention-to-treat population of 210 patients who had baseline WOMAC pain scores of 9 or higher.
Two injections of XT-150 at a dose of 0.45 mg were found to produce the best effect on WOMAC pain, with a LSM change from baseline of −4.09 vs −2.74 for a single 0.45-mg injection (P = .044).
Dr. Rutman reported that the 0.45-mg dose would be the one moving forward into future studies as this had the best effect when they looked at various patient demographics, including baseline age, gender, body mass index, Kellgren-Lawrence grade, and use of concomitant medications.
XT-150 acts locally, does not integrate into the host genome, and “has a very favorable safety profile,” Dr. Rutman said. As it is not a protein, there is no antibody response, and this gives it the possibility for repeat dosing, with no drug-drug serious adverse events so far reported.
The Best Is Yet to Come?
“There’s a lot of things cooking that haven’t been presented here [at OARSI],” Dr. Lane observed.
“We are figuring out how to regenerate cartilage, and it’s a little different than throwing some stem cells in there. There’s some ground-breaking stuff [coming], it just takes us a while.”
Dr. Lane also noted that researchers were “really figuring out” how joints become painful, which will be a major step in figuring out how to make them less painful for patients.
“We’re making a lot of progress in ways that I don’t think we previously thought of, for example, the weight loss drugs. They probably have a central pain reduction effect, I think there’s a little overlap with the opioid receptors, so that’s pretty exciting. So, we’re getting there,” Dr. Lane said.
The congress was sponsored by the Osteoarthritis Research Society International.
Dr. Lane had no relevant conflicts to declare. The trial of PTP-001 (MOTYS) was funded by Bioventus. Ms. Pavesio is an employee of Doron Therapeutics, a subsidiary of Bioventus. The SPRINGBOARD trial with EP-104IAR was funded by Eupraxia Pharmaceuticals. Dr. Helliwell is an employee and stockholder of Eupraxia Pharmaceuticals. The trial of PPS was funded by Paradigm Biopharmaceuticals. Dr. Ahuja is an employee and stockholder of Paradigm Biopharmaceuticals and holds stock in ChitogenX. The trial of XT-150 was funded by Xalud Therapeutics. Dr. Rutman is an employee and equity holder of the company.

Exploratory analyses of synovial fluid biomarkers showed PPS could be having a direct inflammatory effect, with reductions in several proinflammatory cytokines, such as IL-6 and tumor necrosis factor alpha.
An assessment of OA disease progression using MRI analysis suggested that there may be an effect on cartilage thickness and volume, as well as bone marrow lesions and overall joint inflammation.
Gene Therapy
Elsewhere at OARSI 2024, updated data were reported on XT-150, a non-viral, plasmid-based gene therapy designed to express a proprietary variant (v) of IL-10.
Howard Rutman, MD, MBA, chief medical officer of Xalud Therapeutics, reported data from a patient subgroup analysis of a phase 2 trial, which evaluated the effects of single and repeat IA injections of XT-150.
Previously, it was found that a single dose of XT-150 (0.15 mg/mL or 0.45 mg/mL) given as a 1-mL IA injection did not meet its primary endpoint of a greater proportion of patients achieving a 30% or more improvement in WOMAC pain at 180 days vs a matching placebo.
However, it was noted that 17% of the patients in the trial had a baseline WOMAC pain score of less than 8, so the new analysis focused on a modified intention-to-treat population of 210 patients who had baseline WOMAC pain scores of 9 or higher.
Two injections of XT-150 at a dose of 0.45 mg were found to produce the best effect on WOMAC pain, with a LSM change from baseline of −4.09 vs −2.74 for a single 0.45-mg injection (P = .044).
Dr. Rutman reported that the 0.45-mg dose would be the one moving forward into future studies as this had the best effect when they looked at various patient demographics, including baseline age, gender, body mass index, Kellgren-Lawrence grade, and use of concomitant medications.
XT-150 acts locally, does not integrate into the host genome, and “has a very favorable safety profile,” Dr. Rutman said. As it is not a protein, there is no antibody response, and this gives it the possibility for repeat dosing, with no drug-drug serious adverse events so far reported.
The Best Is Yet to Come?
“There’s a lot of things cooking that haven’t been presented here [at OARSI],” Dr. Lane observed.
“We are figuring out how to regenerate cartilage, and it’s a little different than throwing some stem cells in there. There’s some ground-breaking stuff [coming], it just takes us a while.”
Dr. Lane also noted that researchers were “really figuring out” how joints become painful, which will be a major step in figuring out how to make them less painful for patients.
“We’re making a lot of progress in ways that I don’t think we previously thought of, for example, the weight loss drugs. They probably have a central pain reduction effect, I think there’s a little overlap with the opioid receptors, so that’s pretty exciting. So, we’re getting there,” Dr. Lane said.
The congress was sponsored by the Osteoarthritis Research Society International.
