What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called IDP-023 (experimental treatment) combined with IL-2 and ocrelizumab to evaluate its safety and effectiveness in individuals with difficult-to-treat progressive multiple sclerosis (MS). The study consists of two parts: one to determine the optimal dose and another to further test that dose. It seeks participants with primary or non-active secondary progressive MS who have received ocrelizumab in the past six months. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive it.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, since participants must have been dosed with ocrelizumab within the prior 6 months, it seems that continuing this medication is required.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that ocrelizumab, a treatment for multiple sclerosis (MS), has undergone safety studies. Some patients reported side effects such as delayed-onset neutropenia, a condition where white blood cell levels drop, increasing infection risk. IDP-023 remains in early testing stages, so complete safety details are not yet available. Early trials like this one assess how well people tolerate new treatments and identify possible side effects. Prospective participants should discuss potential risks and benefits with their healthcare provider. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for multiple sclerosis?

Researchers are excited about IDP-023 for multiple sclerosis (MS) because it introduces a novel approach by combining it with IL-2 and ocrelizumab. Unlike standard MS treatments, which often focus on reducing inflammation or suppressing the immune system, this combination aims to modulate immune responses more precisely. IDP-023 may offer enhanced effectiveness by working synergistically with IL-2, an immune system booster, and ocrelizumab, a B-cell depleting agent, potentially leading to improved outcomes for patients. This innovative strategy might provide a new avenue for managing MS, especially for those who do not respond adequately to current therapies like interferons or glatiramer acetate.

What evidence suggests that this trial's treatments could be effective for multiple sclerosis?

Research has shown that ocrelizumab can reduce relapse frequency and slow disability progression in people with multiple sclerosis (MS). In this trial, IDP-023, researchers are studying a new therapy using natural killer (NK) cells in combination with ocrelizumab and interleukin-2. This combination aims to help the immune system better target the harmful cells causing MS. Early results suggest that this approach might improve the body's ability to fight MS by focusing on specific immune cells. The goal is to enhance the immune system's response, especially in challenging cases. ^{1 2 6 7 8}

Published Research Related to This Trial

In a study of 130 individuals with relapsing and progressive multiple sclerosis, treatment with ocrelizumab led to significant improvements in health-related quality of life (HRQOL) after 12 months, particularly in mental health domains.

The improvements were measured using patient-reported outcome tools, showing enhanced scores in areas like vitality, emotional health, and reduced anxiety, indicating that ocrelizumab not only affects physical symptoms but also positively impacts mental well-being.

The impact of ocrelizumab on health-related quality of life in individuals with multiple sclerosis. Glanz, BI., Zurawski, J., Casady, EC., et al.[2022]

Ocrelizumab significantly reduces relapse rates and disability progression in adults with relapsing-remitting multiple sclerosis (RRMS) compared to interferon beta-1a, with moderate-certainty evidence from studies involving 2551 participants.

For primary progressive multiple sclerosis (PPMS), ocrelizumab may lead to a higher rate of adverse events compared to placebo, but it also shows potential in reducing disability progression, based on low-certainty evidence from trials lasting at least 120 weeks.

Ocrelizumab, an anti-CD20 monoclonal antibody, is effective in reducing disability progression in primary progressive multiple sclerosis, but it can lead to severe late-onset neutropenia as a rare side effect.

In a reported case, a 34-year-old male developed severe neutropenia 42 days after receiving ocrelizumab, requiring hospitalization and treatment, highlighting the need for patient awareness and monitoring for symptoms like fever.

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.

In a post hoc analysis of pivotal trials, ocrelizumab significantly reduced the risk of confirmed disability progression in multiple sclerosis patients with higher baseline disability (Expanded Disability Status Scale scores ≥4.0).

The analysis included patients from the OPERA trials (relapsing MS) and ORATORIO trial (primary progressive MS), showing that ocrelizumab was more effective than interferon β-1a and placebo in slowing disability progression.

In a phase 3 trial involving 680 patients with relapsing-remitting multiple sclerosis who had previously shown suboptimal responses to other treatments, ocrelizumab achieved a high rate of 'no evidence of disease activity' (NEDA) at 74.8% after 96 weeks, indicating its efficacy in managing the disease.

The highest NEDA rates were observed in patients enrolled based on MRI activity alone (80.6%) and those with lower disability scores (EDSS <2.5), suggesting that ocrelizumab is particularly effective in these subgroups, with no new safety concerns reported.

Patients with relapsing multiple sclerosis treated with ocrelizumab (OCR) showed significantly reduced immune responses to certain vaccines compared to those receiving standard treatment, indicating that OCR may impair the effectiveness of nonlive vaccines.

Despite the attenuated responses, patients on OCR can still mount a potentially protective humoral response to seasonal influenza vaccines, suggesting that vaccination remains important for these patients.

Ocrelizumab is the first approved treatment for both relapsing-remitting multiple sclerosis (RRMS) and primary progressive multiple sclerosis (PPMS), demonstrating significant efficacy in slowing disability progression in PPMS patients at 12 and 24 weeks.

The safety profile of ocrelizumab aligns with findings from clinical trials, showing no unexpected safety concerns, which supports its use in managing multiple sclerosis.

In a study of 228 multiple sclerosis patients treated with ocrelizumab, 91.2% of those with relapsing forms of MS achieved no evidence of disease activity (NEDA) after one year, indicating strong effectiveness in managing the disease.

The treatment was generally well-tolerated, with the most common side effects being infusion-related reactions and infections, particularly urinary tract infections, suggesting a favorable safety profile in a real-world clinical setting.
