Brief Summary:
This dose-escalating phase I trial assesses for the first time the safety, the side effects and the harmlessness, as well as the therapeutical benefit of the new study drug UniCAR02-T-pPSMA in patients with progressive disease after standard systemic therapy in castration-resistant prostate cancers with positive PSMA marker. The UniCAR02-T-pPSMA drug is a combination of a cellular component (UniCAR02-T) with a recombinant antibody derivative (TMpPSMA) which together forms the active drug.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Experimental: UniCAR02-T-pPSMA
Preconditioning (lymphodepletion) with cyclophosphamide and fludarabine, followed by combination treatment of genetically modified T-cells carrying universal chimeric antigen receptors (UniCAR02-T) with the peptide TMpPSMA.
Drug: Cyclophosphamide (Non-IMP)
Intravenous infusion for 3 days

Drug: Fludarabine (Non-IMP)
Intravenous infusion for 3 days

Drug: UniCAR02-T-pPSMA
Intravenous Infusion for 21 days

Drug: UniCAR02-T (IMP)
Intravenous infusion of single dose

Primary Outcome Measures :
  1. Safety and tolerability [ Time Frame: DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression) ]
    Incidence and intensity of adverse events graded according to CTCAE V5.0 with the exception of CRS and ICANS graded according to Lee et al. 2014 and Lee et al. 2019 respectively

  2. Incidence of dose limiting toxicity (DLT) [ Time Frame: DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression) ]
    DLT is defined as any adverse event at least possible related to TMpPSMA and/or UniCAR02-T

  3. Maximum tolerated dose (MTD) [ Time Frame: DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression) ]
    The dose for which the isotonic estimate of the DLT probability is closest to the target DLT probability of 0.2.

Secondary Outcome Measures :
  1. Recommended phase 2 dose (RP2D) [ Time Frame: DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression) ]
    The RP2D will be determined based on MTD, all available efficacy data, and all available safety data, including information derived from additional treatment cycles.

  2. Antitumor activity [ Time Frame: DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression) ]
    Antitumor activity of UniCAR02-T-pPSMA at any time point according to irRECIST (immune-related) Response Evaluation Criteria in Solid Tumors): Complete remission (CR) and partial remission (PR), Objective response rate (ORR), Disease control rate (DCR), Best response rate, Duration of response (DOR),Progression free survival (PFS)

  3. Prostate specific antigen (PSA) response [ Time Frame: DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression) ]
  4. Overall Survival (OS) [ Time Frame: Until fifteen years after last UniCAR02-T administration ]
  5. Influence on Circulating tumor cells (CTC) [ Time Frame: Before start of lymphodepletion therapy until 6 resp. 12 months after start of last TMpPSMA application ]
