Descriptive Information
Brief Title  ICMJE Adoptive SARS-CoV-2 Specific T Cell Transfer in Patients at Risk for Severe COVID-19
Official Title  ICMJE A Randomized Phase I/II Trial to Analyse Safety and Efficacy of Adoptive SARS-CoV-2 Specific T Cell Transfer in Patients at Risk for Severe COVID-19
Brief Summary Monocentric open phase I (dose escalation component), followed by a multi-center, randomized, phase II component benchmarking IMP+SoC against SoC
Detailed Description

The clinical trial will consist of a phase I and a phase II part. The main trial objective in the phase I part is to determine the recommended phase II dose (RP2D) of adoptive SARS-CoV 2-specific T cells by evaluation of safety and tolerability.

In the phase II part, the primary objective is to gain first data on efficacy of adaptive therapy with adoptive SARS-CoV-2-specific T cells. This will be a randomized, prospective feasibility trial.

All study patients at WHO ordinal scale ≥ 5 will receive the current SoC for treatment of Covid-19. Currently this is remdesivir (loading dose 200mg i.v. on day 1, 100mg maintenance dose day two to five (up to day 10), dexamethasone 6mg once daily p.o. or i.v. up to day 10 and a subcutaneous thromboembolism prophylaxis with low molecular-weight heparin. Due to the dynamic of the ongoing COVID-19 pandemic, SoC treatments are underlying rapid changes and are continuously developed. Therefore, SoC treatment as defined at the time of respective IMP dosing, will be administered.

The adoptive SARS-CoV-2 specific T cells are suspended and formulated in 50 ml of platelet additive solution and will be administered intravenously within 15 min to 30 min.

Intervention Model Description:

The clinical trial will consist of a phase I and a phase II part. The main trial objective in the phase I part is to determine the recommended phase II dose (RP2D) of SARS-CoV-2-specific T cells by evaluation of safety and tolerability.

In the phase II part the primary objective is to gain first data on efficacy of adoptive therapy with SARS-CoV-2-specific T cells. This will be a randomized, prospective feasibility trial.

Masking: None (Open Label)
Masking Description:

During the dose-escalation phase I of this clinical trial, the study participants and the study team are aware of the treatment as this is an open label trial.

During phase II both study participants and the study team are aware of the treatment as this again is an open label trial.

    All study patients at WHO Ordinal Scale ≥ 5 will receive the current SoC for treatment of COVID-19. Currently this is remdesivir (loading dose 200 mg i.v. on day 1, 100 mg maintenance dose day two to five (up to day 10)) - only WHO Ordinal Scale 5, dexamethasone 6 mg once daily p.o. or i.v. up to day 10 and a subcutaneous thromboembolism prophylaxis with low molecular-weight heparin.

  • Drug: IMP RP2D plus SoC

    Intravenous administration adoptive SARS-CoV-2 specific T cells (IMP) at Recommended Phase II Dose (RP2D).

    The adoptive SARS-CoV-2 specific T cells are suspended and formulated in 50 ml of platelet additive solution and will be administered intravenously within 15 min to 30 min.

  • Drug: SoC

    Patients will receive the current SoC for treatment of COVID-19.

    Currently this is remdesivir (loading dose 200 mg i.v. on day 1, 100 mg maintenance dose day two to five (up to day 10)) - only WHO Ordinal Scale 5, dexamethasone 6 mg once daily p.o. or i.v. up to day 10 and a subcutaneous thromboembolism prophylaxis with low molecular-weight heparin.

Study Arms  ICMJE
  • Experimental: Phase I dose level 1
    Dose level one consists of 3 study patients receiving 1,000 adoptive SARS-CoV-2 specific T cells (IMP) per kg BW. If the first recipient does not experience a DLT associated with the dose level one therapeutic cells within 28 days, the second and third patient will receive 1.000 SARS-CoV-2 adoptive SARS-CoV-2 specific T cells per kg BW. If patient second and third do not experience a DLT within 14 days after treatment, the dose level two will be initiated.
    Intervention: Drug: IMP 1,000 plus SoC
  • Experimental: Phase I dose level 2
    Dose level two consists of 3 study patients receiving 5.000 adoptive SARS-CoV-2 specific T cells (IMP) per kg BW. If the fourth patient does not experience a DLT associated with the dose level two within 28 days, the fifth and sixth patient will receive 5.000 adoptive SARS-CoV-2 specific T cells per kg BW.
    Intervention: Drug: IMP 5,000 plus SoC
  • Experimental: Phase II SoC plus IMP at the RP2D
    Phase II SoC plus IMP at the RP2D consists of 26 patients treated with SoC plus adoptive SARS-CoV-2-specific T cells at the RP2D (Recommended Phase II Dose).
