A Study to Investigate Ronde-cel Versus Investigator's Choice CD19 CAR T-Cell Therapy

Официальное название

A Phase 3 Randomized Controlled Trial of Rondecabtagene Autoleucel , an Autologous, Dual-targeting CD19/CD20 CAR T-Cell Product Candidate, Vs. Investigator's Choice of CD19 CAR T-Cell Therapy in Patients With Relapsed or Refractory Large B-Cell Lymphoma in the Second-line Setting

Обзор

This Phase 3 study compares rondecabtagene autoleucel (ronde-cel), a dual-targeting CD19/CD20 CAR T-cell therapy, with investigator's choice of CD19 CAR T-cell therapy in patients with relapsed or refractory large B-cell lymphoma in the second-line setting.

Подробное описание

PiNACLE-H2H is a Phase 3 randomized controlled trial comparing the efficacy and safety of rondecabtagene autoleucel (ronde-cel, formerly known as LYL314) against the currently approved cluster of differentiation (CD)19 chimeric antigen receptor (CAR) T-cell therapies (axicabtagene ciloleucel \[axi-cel\] or lisocabtagene maraleucel \[liso-cel\]), in patients with aggressive LBCL that has relapsed or is refractory to first-line anti-CD20 antibody and anthracycline-containing chemotherapy.

Patients will be randomized (1:1) before leukapheresis to receive either:

* Ronde-cel; or * Investigator's choice of axi-cel or liso-cel

Most patients who receive currently approved CD19-directed CAR T-cell therapies, including axi-cel and liso-cel, still experience progressive disease, often due to mechanisms such as CD19 antigen loss or T-cell exhaustion.

Ronde-cel is a novel, autologous, dual-targeting CD19/CD20 CAR T-cell product candidate enriched for CD62L-positive naïve and central memory T cells, which are associated with enhanced proliferation capacity and persistence. Ronde-cel is an "OR"-gated CAR construct that can fully activate upon recognition of either CD19 or CD20, aiming to improve durability of response despite antigen heterogeneity.

Approximately 400 participants will be enrolled. CAR T-cell therapy in both arms will be administered as a single intravenous infusion following fludarabine and cyclophosphamide lymphodepletion. Participants will be followed for 3 years for safety and efficacy, with long-term follow-up extending to 15 years.
