What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if a new treatment, GLPG5101 (a type of CAR T-cell therapy), is safe and effective for people with non-Hodgkin lymphoma (NHL). In the first phase, researchers will identify which doses of GLPG5101 are most effective with the fewest side effects. The second phase will administer these selected doses to participants to evaluate their efficacy. Individuals with a confirmed diagnosis of certain types of NHL, who have relapsed or not responded to previous treatments, and have at least one measurable tumor may be eligible to participate. As a Phase 1 and Phase 2 trial, this research seeks to understand how the treatment works in people and measure its effectiveness in an initial, smaller group, offering participants a chance to be among the first to benefit from this innovative therapy.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that GLPG5101 is likely to be safe for humans?

Research shows that GLPG5101 could be a promising treatment for non-Hodgkin's lymphoma. This treatment is a type of CAR-T therapy, which uses a person's own immune cells to fight cancer. In earlier studies, most patients who received GLPG5101 tolerated it well, experiencing no severe side effects.

Testing any new treatment carries risks, but GLPG5101 has undergone early studies to assess its safety. Common side effects in similar treatments include fever, tiredness, and decreased blood cell counts, which are usually manageable with medical care. As this trial continues, researchers closely monitor the treatment to ensure its safety.

Prospective participants should consult a healthcare provider to weigh the risks and benefits based on personal health needs. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for non-Hodgkin's lymphoma?

Researchers are excited about GLPG5101 for non-Hodgkin's lymphoma because it represents a novel treatment approach compared to standard therapies like chemotherapy and immunotherapy. Unlike traditional treatments, GLPG5101 involves an intravenous cell suspension designed to target specific disease subtypes directly. This targeted approach could potentially offer more personalized and effective treatment, minimizing the broad side effects often associated with conventional therapies. Additionally, the study explores different dosing levels and cohorts, which might help identify the optimal effective dose for various lymphoma subtypes, paving the way for more tailored cancer treatments.

What evidence suggests that GLPG5101 might be an effective treatment for non-Hodgkin's lymphoma?

Studies have shown that GLPG5101, a CD19 CAR-T cell therapy, can effectively treat non-Hodgkin lymphoma (NHL), particularly in patients whose cancer has returned or resisted other treatments. Research indicates that CAR-T cells, specially modified immune cells, have successfully targeted and destroyed cancer cells in challenging NHL cases. Early results suggest this treatment could extend patients' lives. The therapy is designed for rapid production, enhancing accessibility and usefulness in urgent situations. Overall, early evidence supports its potential effectiveness in treating various NHL types. Participants in this trial will receive GLPG5101 in different treatment arms, including varying dose levels and disease-specific cohorts, to assess its safety and efficacy across a range of NHL subtypes. ^{2 3 4 5 6}

Published Research Related to This Trial

Chimeric antigen receptor (CAR) T cell therapy targeting CD19 and CD20 has shown a promising overall response rate of 61% in treating B-cell hematologic malignancies, with a complete response rate of 42% and partial response rate of 19% across 16 studies involving 195 patients.

However, the therapy is associated with significant adverse events, including cytokine release syndrome and neurotoxicity (both at 33%), and B-cell aplasia in 54% of patients, highlighting the need for careful monitoring during treatment.

Anti-CXCR5 CAR-T cell therapy effectively targets both B cell Non-Hodgkin's lymphoma (B-NHLs) and follicular T helper (Tfh) cells, showing greater potency in eradicating these cells compared to traditional CD19 CAR-T cells in laboratory studies.

In murine models, anti-CXCR5 CAR-T cells specifically deplete both malignant B cells and Tfh cells without causing harmful effects on normal tissues, suggesting a safe and effective treatment strategy for nodal B-NHLs.

In a study involving 16 healthy donors, researchers found that using specific activation conditions (soluble anti-CD3/CD28 mAbs with IL15 and IL21) improved the quality and function of gene-modified T cells, which is crucial for effective cancer treatment.

These optimized T cells showed better binding to target molecules and a more favorable phenotype, suggesting that these methods could enhance the efficacy of CAR and TCR therapies in future clinical trials for patients with certain tumors.
