Evaluating AK129 with or without AK117 for patients with resistant Classic Hodgkin Lymphoma

A Phase I/II Study of AK129 (Bispecific Antibody Targeting LAG-3 and PD-1) Monotherapy or in Combination With AK117 (Anti-CD47 Monoclonal Antibody) in Relapse or Refractory Classic Hodgkin Lymphoma With PD-1/L1 Inhibitor Treatment Failure

Phase1; Phase2 Interventional Akeso · NCT06642792

This study is testing if a new treatment called AK129, alone or with another drug AK117, can help adults with tough-to-treat classic Hodgkin lymphoma feel better after other treatments have failed.

What this trial studies

This clinical trial is designed to assess the safety and effectiveness of AK129, a bispecific antibody targeting LAG-3 and PD-1, either alone or in combination with AK117, an anti-CD47 monoclonal antibody, in patients with relapse or refractory classic Hodgkin lymphoma who have not responded to PD-1/L1 inhibitor therapy. The study includes patients aged 18 and older with a performance status of 0 or 1 and aims to determine the potential benefits of these treatments in this challenging patient population. The trial is conducted in phases I and II to evaluate both initial safety and subsequent efficacy outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with relapse or refractory classic Hodgkin lymphoma who have previously failed PD-1/L1 inhibitor therapy.

Not a fit: Patients with nodular lymphocyte-predominant Hodgkin lymphoma or those with central nervous system lymphoma involvement may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with classic Hodgkin lymphoma who have exhausted other treatment avenues.

How similar studies have performed: While this approach is innovative, the success of similar studies using bispecific antibodies in hematological malignancies suggests potential for positive outcomes.
