Nivolumab plus chemotherapy for ALK+ relapsed/refractory ALCL in kids, teens, and young adults

Official title: NYMC623: A Comprehensive Risk-adapted Chemommunotherapy Protocol of Emerging Immunotherapies for Relapsed/Refractory Alk+ Anaplastic Large Cell Lymphoma (ACCELERATE)

Run by New York Medical College · NCT07013565 · Data updated 2026-11-12

This trial tests whether adding nivolumab to chemotherapy, followed by reduced-dose chemoimmunotherapy and a stem cell transplant, can improve outcomes for young patients with relapsed or refractory ALK-positive ALCL.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children, adolescents, and young adults with relapsed or refractory ALK-positive ALCL meeting specific low- or high-risk criteria and who can receive the planned therapies.

Probably not a fit

Patients who do not respond to nivolumab-containing therapy or who cannot proceed to stem cell transplantation may not experience benefit.

What this trial studies

This phase 2 study evaluates a chemoimmunotherapy approach for children, adolescents, and young adults with relapsed or refractory ALK-positive ALCL. Participants start with nivolumab plus chemotherapy based on risk, aiming to achieve the best possible response, then continue with lower-dose chemoimmunotherapy and an allogeneic stem cell transplant. The trial builds on prior data suggesting benefit from CD30-targeted therapy and PD-1/PD-L1 blockade in related lymphomas. Primary safety and efficacy outcomes will inform whether this strategy can improve survival in a high-risk population. The study is conducted at multiple centers with New York Medical College as the lead sponsor.

Why it matters

Potential benefit: If successful, patients may achieve better tumor control and longer survival with a tailored, risk-adapted treatment plan.

How similar studies have gone: Prior data show promising activity of brentuximab vedotin with chemotherapy and PD-1 inhibitors in related lymphomas, though results in ALK+ ALCL are still being explored.
