What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness of Ocrelizumab (also known as Ocrevus or Ocrevus Zunovo) for individuals with early-stage relapsing multiple sclerosis (RMS). The researchers aim to determine whether continuing or stopping the medication after two years affects condition management. Participants will receive either Ocrelizumab or a placebo (a substance with no active drug) every six months for four years. This study may suit those who have had RMS for less than two years and experience symptoms meeting specific criteria. As a Phase 4 trial, this research seeks to understand how the already FDA-approved and effective treatment benefits more patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, certain treatments like systemic corticosteroids and some MS therapies are not allowed before the trial starts. It's best to discuss your specific medications with the study team.

What is the safety track record for Ocrelizumab?

Research has shown that Ocrelizumab is generally safe for people. In a previous study, about 70% of patients who took Ocrelizumab experienced one or more infections, similar to the 68% of patients who took a placebo (a harmless pill with no active medicine), suggesting the risk is not significantly higher. Some patients reported reactions to the injections, such as a rash or fever, but these are usually manageable.

The FDA has already approved Ocrelizumab for treating certain types of multiple sclerosis, indicating it has passed many safety checks. While awareness of possible side effects is important, many patients find the treatment tolerable. Always discuss potential risks and benefits with a healthcare provider. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Ocrelizumab is unique because it specifically targets CD20-positive B cells, a type of immune cell involved in the progression of multiple sclerosis (MS). Unlike other treatments like interferons or glatiramer acetate, which modulate the immune system more broadly, ocrelizumab offers a more targeted approach, potentially leading to fewer side effects and more effective management of the disease. Researchers are excited about ocrelizumab because it has shown promise in reducing relapse rates and slowing the progression of disability in MS patients, offering new hope for improved quality of life.

What is the effectiveness track record for Ocrelizumab in treating multiple sclerosis?

Research has shown that Ocrelizumab effectively treats multiple sclerosis (MS). Studies have found it can reduce the risk of worsening disability by about 30% in people with MS. In this trial, participants in the Ocrelizumab arm will receive this treatment, which has resulted in fewer symptoms worsening compared to those in the placebo arm, who will receive a placebo infusion. Ocrelizumab is also the only approved treatment for primary progressive multiple sclerosis (PPMS), demonstrating its ability to help delay disability. These findings suggest that Ocrelizumab can be a helpful option for managing MS symptoms. ^{2 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Ocrelizumab
• Placebo for Ocrelizumab

Trial Overview The study tests if it's safe and effective to stop Ocrelizumab (OCR) after initial treatment in RMS patients. It starts with standard OCR doses for a year; then participants are randomly assigned to continue OCR, switch from OCR to placebo at different intervals, or receive placebos only for up to four years.

How Is the Trial Designed?

Group I: Ocrelizumab Arm Experimental Treatment 1 Intervention

All eligible participants will be initiated on OCR using the standard approved administration schedule of two 300 mg infusions separated by 14 days (i.e., Days 0 and 14) for a total of 600 mg, followed by 600 mg infusions at Month 6, 12, 18, and 24. In this arm participants will continue to receive OCR infusions every 6 months through Month 48.

Group II: Placebo Arm Placebo Group 1 Intervention

All eligible participants will be initiated on OCR using the standard approved administration schedule of two 300 mg infusions separated by 14 days (i.e., Days 0 and 14) for a total of 600 mg, followed by 600 mg infusions at Month 6, 12, 18, and 24. In this arm, starting at Month 30, participants will receive placebo infusions every 6 months through Month 48.

Published Research Related to This Trial

Ocrelizumab is a humanized anti-CD20 monoclonal antibody specifically designed to deplete B cells, which are implicated in the development of multiple sclerosis (MS).

Approved in March 2017 in the USA for treating both relapsing and primary progressive forms of MS, ocrelizumab represents a significant advancement in MS therapy, with its approval in the EU currently pending.

Ocrelizumab: First Global Approval. Frampton, JE.[2022]

Ocrelizumab significantly reduces annualized relapse rates in adults with relapsing multiple sclerosis (RMS) compared to interferon β-1a, based on results from two 96-week trials.

In patients with primary progressive multiple sclerosis (PPMS), ocrelizumab significantly lowers the risk of confirmed disability progression over 120 weeks compared to placebo, and it is generally well tolerated with mostly mild to moderate side effects.

In a review of 78 studies involving 4498 patients, 61.3% of those treated with ocrelizumab experienced adverse events, with the most common being infections (39.2%) and infusion-related reactions (26.2%).

Ocrelizumab was associated with a higher risk of infections compared to beta-interferon, particularly herpes-related and respiratory infections, while the risk of serious adverse events was similar between ocrelizumab and comparator groups.

Ocrelizumab, a monoclonal antibody used for treating multiple sclerosis, can be associated with the development of alopecia areata, as observed in five patients (two females and three males).

All patients responded positively to conventional treatments for alopecia areata, such as corticosteroids and minoxidil, indicating that this side effect is potentially reversible with appropriate care.
