Phase 2 Study Evaluating Autologous CD30.CAR-T Cells in Patients With Relapsed/Refractory Hodgkin Lymphoma (CHARIOT)

A Phase 2 Multi-Center Study Evaluating the Safety and Efficacy of CD30-Directed Genetically Modified Autologous T Cells (CD30.CAR-T) in Adult and Pediatric Patients With Relapsed or Refractory Classical Hodgkin Lymphoma

This is a two-part, Phase 2, multicenter, open-label, single arm study to evaluate the safety and efficacy of autologous CD30.CAR-T in adult and pediatric subjects with relapsed or refractory CD30+ classical Hodgkin Lymphoma.

Study Overview

• Status: Active, not recruiting
• Conditions: Hodgkin Lymphoma, Adult; Hodgkin Disease Recurrent; Hodgkin Disease Refractory; Hodgkin Disease, Pediatric
• Intervention / Treatment: Drug: CD30.CAR-T; Drug: Fludarabine; Drug: Bendamustine

Detailed Description

The Pilot part of the study will evaluate the safety, tolerability, and preliminary antitumor efficacy of CD30.CAR-T. The Pivotal part of the study will evaluate antitumor efficacy and further evaluate safety and tolerability. All study eligibility requirements, assessments, procedures, and follow-up are the same for patients in both Pilot and Pivotal parts of the study.

Subjects who meet eligibility criteria will have their blood drawn by leukapheresis for manufacture the CD30.CAR-T cells. Subjects are allowed bridging chemotherapy, as per Investigator choice, while waiting for production of CD30.CAR-T. Lymphodepletion (LD) with fludarabine and bendamustine will be administered for 3 consecutive days starting on Day -5 to Day -3, prior to CD30.CAR-T infusion, which will be administered on Day 0 as a single IV infusion. Depending on disease status, eligible subjects may receive up to a total of two CD30.CAR-T infusions at the same dose, each with preceding LD chemotherapy.

Subjects will be closely monitored for safety and efficacy throughout the Treatment Period until the end of study (EOS) visit at Month 24. Subjects will be followed for survival, withdrawal of consent or study closure, whichever occurs first. Health Related Quality of Life assessments will also be collected throughout the study. After the EOS visit, subjects will enter the long-term follow-up phase (LTFU) which will include survival follow-up, additional safety, efficacy and biomarker assessments, as clinically indicated.
