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 viable human 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 viable human SARS-CoV-2-specific T cells. This will be a randomized, prospective feasibility trial. Details to phase II will be updated after completion of phase I.

Interventions

DRUGhuman SARS-CoV 2 specific T lymphocytes

In dose level one, SARS-CoV-2 infected patients will receive 1,000 viable human SARS CoV-2 specific T lymphocytes per kg BW. In dose level two SARS-CoV-2 infected patients will receive 5,000 viable human SARS CoV-2 specific T lymphocytes per kg BW. In parallel, all patients will receive the current SoC treatment for COVID-19.

Exclusion criteria

* Participation in any other clinical trial of an experimental agent treatment * Active GvHD or history of GvHD * History of CAR-T-Cell Therapy * COVID-19 WHO ordinal scale ≥6 * Anticipated life-expectancy \<72 hours * Expected duration of hospital stay \<72 hours * Sepsis-induced leukopenia or thrombocytopenia (leukocytes \<1,000/µl or platelets \<50,000/µl). If the cytopenias result from underlying hematologic disease or its treatment this will not be regarded as exclusion criterion * CT pneumonia score ≥13 \[50\] * Any Steroids ≥1 mg/kg Prednisolon-equivalent/kg BW, besides 6 mg Dexamethasone i.v. or p.o. 1x/d as SoC for COVID-19 * Pregnant or breast feeding * Any serious medical condition or abnormality of clinical laboratory tests that, in the Investigator's judgment, precludes the subject's safe participation in and completion of the study * Therapeutic donor lymphocyte infusion (DLI) less than 100 days prior to IMP infusion * Known hypersensitivity to iron dextran * Known pre-existing human anti-mouse antibodies (HAMAs) * ontraindication against mandatory protocol-inherent comedication(s): antihistamine and/or acetaminophen * Failure to use highly-effective contraceptive methods.
