Assessing how ABBV-453 works in adults with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma

A Phase 1 Study Evaluating Safety, Pharmacokinetics, and Efficacy of ABBV-453 in Adult Subjects With Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL)

Phase 1 Interventional AbbVie · NCT06291220

This study is testing a new drug called ABBV-453 to see if it can help adults with relapsed or hard-to-treat chronic lymphocytic leukemia or small lymphocytic lymphoma feel better.

What this trial studies

This study evaluates the investigational drug ABBV-453 in adult participants with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). It consists of two parts: the first part involves administering escalating doses of ABBV-453 alongside obinutuzumab during a debulking period, while the second part continues with the maximum dose established in part A. The study aims to assess the drug's pharmacokinetics, adverse events, and changes in disease activity among approximately 80 participants across 40 sites worldwide.

Who should consider this trial

Good fit: Ideal candidates are adults with relapsed or refractory CLL/SLL who have received at least two prior systemic therapies and have no available therapies that provide clinical benefit.

Not a fit: Patients who are BCL-2 inhibitor refractory or have received a BCL-2 inhibitor within the last six months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with relapsed or refractory CLL/SLL.

How similar studies have performed: Other studies have shown promise with similar investigational approaches, but the specific use of ABBV-453 in this context is novel.
