Official title

A Phase 1a/b Study to Evaluate the Safety and Efficacy of OPB 201, an Autologous PReferentially Expressed Antigen of MElanoma (PRAME) T Cell Receptor (TCR) T Cell Therapy in Recurrent Endometrial and Platinum-resistant Ovarian Cancer.

Overview

The goal of this clinical trial is to learn if OPB-201 is safe in recurrent endometrial and platinum resistant ovarian cancer participants and also to find the optimal dose of OPB-201. Participants will have their own T cells modified in a laboratory and given back to them as OPB-201 in this one-time treatment. Participants will be in the hospital when they receive OPB-201 and then be checked at the clinical site frequently for the first few months.

Detailed description

A phase 1a/b study to evaluate the safety and efficacy of OPB-201, an autologous PReferentially expressed Antigen of MElanoma (PRAME) T cell receptor (TCR) T cell therapy in recurrent endometrial and platinum-resistant ovarian cancer.

Interventions

  • Biological OPB-201
    A multi-transgene autologous TCR T cell therapy with optimized alpha and beta chains of a TCR specific for a peptide derived from PRAME and a designed protein which enhances TCR T cell potency.

Primary outcome measures

  • Safety [Time frame: 2 years]
  • Safety [Time frame: 28 days]
  • Safety [Time frame: 2 years]

Eligibility criteria

  • Received prior therapy with a PARP inhibitor if the subject has a known germline or somatic BRCA1/2 mutation.
  • Measurable disease.
  • Consent to provide archived tumor tissue sample.
  • ECOG performance status of 0 or 1.
  • Adequate organ function.
  • HLA-A \*02:01 or HLA-A \*02:02
