What is the purpose of this trial?

This trial explores how a new treatment, rapcabtagene autoleucel (YTB323), can help individuals with non-active Progressive Multiple Sclerosis (PMS). Researchers aim to assess the treatment's safety, its effect on disease progression, and its movement through the body. Participants will receive a single dose of YTB323 to evaluate its impact on their condition. The trial seeks individuals diagnosed with secondary or primary progressive multiple sclerosis (SPMS or PPMS) who have shown recent disease progression but have not experienced any relapses in the past year. As a Phase 1 trial, this research focuses on understanding the treatment's effects in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on anticoagulants or antiplatelet drugs, you may not be eligible, except for low-dose aspirin or ibuprofen.

Is there any evidence suggesting that rapcabtagene autoleucel (YTB323) is likely to be safe for humans?

Research has shown that rapcabtagene autoleucel (YTB323) is generally well-tolerated. Early results from other clinical trials indicate a good safety record. In studies with patients who have similar conditions, safety outcomes were positive. Some participants experienced side effects, but these were mostly manageable. The treatment also demonstrated promising results in its mechanism of action and effectiveness against disease symptoms. This suggests that YTB323 could be a safe option for those considering joining a clinical trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for Multiple Sclerosis?

Unlike the standard treatments for multiple sclerosis, which often include disease-modifying therapies like interferons and monoclonal antibodies, YTB323 is a novel approach using rapcabtagene autoleucel, a type of CAR-T cell therapy. This treatment is unique because it harnesses the power of the patient's own immune cells, which are genetically modified to better target and attack disease-specific cells. Researchers are excited about YTB323 because it represents a personalized treatment strategy that could potentially offer more effective and longer-lasting control of multiple sclerosis symptoms, with the added promise of fewer side effects compared to traditional therapies.

What evidence suggests that YTB323 might be an effective treatment for Progressive Multiple Sclerosis?

Research has shown that rapcabtagene autoleucel (YTB323) delivers promising results in early tests. At a certain dose, it proved effective and safe. This trial will evaluate YTB323 across different cohorts, each receiving one dose of the treatment. YTB323 targets specific immune system cells, potentially slowing the progression of multiple sclerosis. Although only a few patients have been tested so far, initial results suggest that YTB323 could benefit individuals with non-active Progressive Multiple Sclerosis. These early findings offer hope for managing the condition. ^{1 2 5 6 7}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-60 with Progressive Multiple Sclerosis (PMS) who can handle certain medical procedures like lumbar punctures and MRIs. They should have a confirmed diagnosis of SPMS or PPMS, be able to walk (EDSS ≤6.5), show recent disease progression, and have had PMS for less than 15 years without relapses or new brain lesions in the last year.

Inclusion Criteria

My condition is diagnosed as SPMS or PPMS according to 2017 criteria.

I have signed the consent form to participate in this study.

My latest brain MRI showed no enhancing lesions.

Published Research Related to This Trial

Equecabtagene autoleucel (Fucaso®) is a CAR-T cell therapy specifically designed to target B cell maturation antigen (BCMA) and has been conditionally approved in China for treating adults with relapsed or refractory multiple myeloma (RRMM) after at least three prior therapies.

This therapy represents a significant advancement in treatment options for RRMM patients, particularly those who have not responded to other treatments, highlighting its potential efficacy in a challenging patient population.

Equecabtagene Autoleucel: First Approval. Keam, SJ.[2023]

The three CAR-T cell therapies (axicabtagene ciloleucel, tisagenlecleucel, and lisocabtagene maraleucel) show promising efficacy in treating large B cell lymphoma, with overall response rates of nearly 70% and complete response rates exceeding 50% across 33 studies involving 2,172 patients.

However, axicabtagene ciloleucel and tisagenlecleucel are associated with significant risks of severe neurotoxicity and life-threatening cytokine release syndrome, necessitating careful monitoring during treatment.

Axicabtagene ciloleucel and brexucabtagene autoleucel are effective anti-CD19 T-cell therapies that have shown high response rates in patients with relapsed and refractory B-cell malignancies, leading to FDA approvals for specific types of lymphoma.

Despite their effectiveness, these therapies can cause significant toxicities, such as cytokine release syndrome and neurologic issues, which necessitate careful management and monitoring during treatment.

Yescarta (axicabtagene ciloleucel) is an engineered T-cell therapy that showed a 66% overall response rate and a 47% complete response rate in treating relapsed or refractory diffuse large B-cell lymphoma, based on a phase II study with a median follow-up of 15.1 months.

The therapy was associated with manageable adverse events, including cytokine release syndrome and neurological issues, making it a promising option for patients with limited treatment alternatives.

CAR T-cell therapy targeting CD19 has transformed the treatment landscape for relapsed or refractory B-cell lymphomas, leading to rapid FDA approval for multiple lymphoma subtypes due to high response rates and durability.

Three second-generation anti-CD19 CAR T-cell products have been approved for use in aggressive non-Hodgkin's lymphoma, and ongoing research is focused on understanding treatment failures and improving outcomes for patients who do not respond to therapy.
