Ozanimod Shows Positive Response in Relapsing Multiple Sclerosis in Two Clinical Trials

Two phase 3 clinical trials indicate better efficacy and safety of ozanimod for the treatment of relapsing multiple sclerosis.

Multiple sclerosis - Symptoms - Causes - Diagnosis - Treatment
Multiple sclerosis can be a severely disabling autoimmune disease that affects the myelin or insulating layer of the nerve fibers and typically has remissions and relapses

‘Two large clinical trials indicate better efficacy of ozanimod as compared to interferon beta-1a for the treatment of relapsing multiple sclerosis. ’

Highlight:

The results of two phase 3 clinical trials, the SUNBEAM and the RADIANCE Part B, were recently presented
The studies evaluated the efficacy and safety of ozanimod as compared to interferon beta-1a for the treatment of relapsing multiple sclerosis
If the drug receives approval from the regulatory authorities, it will provide an additional option for patients with relapsing multiple sclerosis

Ozanimod appears to have a positive effect and reduces disease progression in relapsing multiple sclerosis, as demonstrated by the results of two phase 3 clinical trials, the RADIANCE Part B and the SUNBEAM trial. The results of the study were presented at the 7th Joint European Committee for Treatment and Research in Multiple Sclerosis-Americas Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS-ACTRIMS) 2017.

Ozanimod was tried in patients with relapsing multiple sclerosis, where patients suffer frequent flare-ups of the disease. The effectiveness and safety of two doses, 0.5mg and 1 mg per day, were compared to interferon beta-1a, which a drug that is currently being used to treat the condition. The RADIANCE Part B Study was conducted on 1320 patients for two years, while the SUNBEAM Study was conducted on 1346 patients who were treated for at least one year. The scientists found that:

Both the doses significantly reduced the annualized relapse rate (ARR) as compared to patients on weekly injections of interferon β-1a.
The number of new and enlarging lesions due to multiple sclerosis in the brain, as demonstrated on MRI, were significantly reduced to a greater extent in patients taking ozanimod as compared to interferon β-1a. Ozanimod significantly slowed the brain loss in the patients as compared to interferon in patients taking 1 mg of ozanimod in the SUNBEAM trial and with both the doses in the RADIANCE Part B trial.
The side effects including the serious effects were similar in the two groups. The most common side effects with ozanimod in both the studies were nasopharyngitis, headache, and upper respiratory tract infection.

The company manufacturing the drug hopes that they will be able to launch it soon in the market, given its positive results in these two studies.

About Ozanimod

Ozanimod is a drug that is a selective sphingosine 1-phosphate 1 (S1PR1) and 5 (S1PR5) receptor modulator. It reduces inflammation and thereby prevents flare-ups in multiple sclerosis. It is administered orally once a day. The drug is also likely to be tested in inflammatory bowel disease that includes ulcerative colitis and Crohn’s disease.

Vegetarian Diet reduces Risk of Relapse in Kids With Multiple Sclerosis
Consuming a diet rich in fats increases the risk of multiple sclerosis (MS) in children. However, a diet rich in vegetables reduces the risk of relapse by halve.

About Multiple Sclerosis

Multiple sclerosis is an autoimmune disorder that results in damage to the myelin sheath surrounding nerves. It causes various neurological symptoms that frequently relapse ultimately resulting in disability. Current treatments are aimed at modifying the course of the disease, relieving symptoms and helping patients cope with the disability through physical therapy.
