Investigating the safety of ONO-4685 for T Cell Lymphoma and CLL/SLL

An Open-label, Uncontrolled, Phase I Dose Escalation Study to Investigate the Tolerability and Safety of ONO-4685 Given as Monotherapy in Patients With Relapsed or Refractory T Cell Lymphoma and Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL)

Phase 1 Interventional Ono Pharmaceutical Co., Ltd. · NCT06547528

This study is testing a new drug called ONO-4685 to see if it is safe and works for people with relapsed T Cell Lymphoma and Chronic Lymphocytic Leukemia who have run out of other treatment options.

What this trial studies

This Phase I clinical trial evaluates the tolerability and safety of ONO-4685 as a monotherapy for patients with relapsed or refractory T Cell Lymphoma and Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma. The study aims to enroll patients who have histopathologically confirmed diagnoses and have exhausted standard treatment options. Participants will be monitored for adverse effects and overall response to the treatment. The trial is designed to gather preliminary data on the drug's safety profile and potential efficacy.

Who should consider this trial

Good fit: Ideal candidates include patients with specific subtypes of T Cell Lymphoma or CLL/SLL who have relapsed or are refractory to existing therapies.

Not a fit: Patients with severe complications or multiple cancers may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with limited treatment alternatives.

How similar studies have performed: While this approach is novel for ONO-4685, similar studies have shown promise in targeting T Cell Lymphoma and CLL/SLL with new therapies.
