Brief Summary:
This is a multicentre, non-randomized, open-label, Phase I/II clinical trial of MDG1011, an investigational medicinal product (IMP), consisting of patient-derived autologous T cells, persistently transduced with a Preferentially Expressed Antigen in Melanoma (PRAME)-specific human leukocyte antigen (HLA)-A*02:01-restricted T cell receptor (TCR).

Safety Tolerability Feasibility Treatment Efficacy Drug: MDG1011 Other: Investigator Choice therapy Phase 1 Phase 2

Detailed Description:

Phase I:

The Phase I dose escalation part will establish the MTD/RP2D in subjects with high risk myeloid and lymphoid neoplasms, a total of 3 disease entities.

Phase I subjects will be enrolled into the following cohorts and treated with a single intravenous (i.v.) infusion of IMP:

  • Cohort 1: target dose of 1 x 105 T cells/kg ± 20%
  • Cohort 2: target dose of 1 x 106 T cells/kg ± 20%
  • Cohort 3: target dose of 5 x 106 T cells/kg ± 20%
  • Optional cohort 4: up to 1 x 107 T cells/kg + 20%

Phase II:

The Phase II part consists of two arms, each representing one disease entity. Within each arm, representing a disease entity, subjects will be enrolled in 2 different treatment groups to receive either:

  1. IMP in the treatment group (up to 20 subjects who are positive for human leukocyte antigen (HLA)-A*02:01); Or
  2. therapy as per Investigator's discretion in the concurrent control (up to 20 subjects who are negative for HLA-A*02:01).
