Phase 1 Study of Allo-RevCAR01-T-CD123 in Patients With Selected CD123 Positive Hematologic Malignancies (1b Dose Expansion) (RevSTAR-123)

21 de septiembre de 2026 actualizado por: AvenCell Europe GmbH

Estudio multicéntrico, abierto, de fase 1 de Allo-RevCAR01-T-CD123 que consta de células T modificadas genéticamente que portan receptores de antígenos quiméricos inversos (Allo RevCAR01 T) en combinación con el módulo diana CD123 (R-TM123) para el tratamiento de pacientes con Neoplasias malignas hematológicas seleccionadas positivas para CD123

The Allo-RevCAR01-T-CD123 drug is a combination of a cellular component (Allo-RevCAR01-T) with a recombinant antibody derivative (R-TM123), which together form the active drug. The cellular component Allo-RevCAR01-T consists of an allogeneic human T-cell genetically multi-edited and expressing a reversed, universal chimeric antigen receptor (RevCAR) presenting an extracellular peptide epitope (RevCAR epitope). R-TM123 functions as a bridging module between Allo-RevCAR01-T and a CD123-expressing target cancer cell by selectively binding the RevCAR epitope and CD123.

Inclusion Criteria (Dose Expansion):

1. Male or female participants, age ≥18 years. 2. HLA type of participant must match at HLA B and C loci 3. Participants with CD123+ AML with morphologically relapsed or refractory disease (>5% BM blasts). CD123 positivity is defined as ≥20% of leukemic cells expressing CD123 at any point in the course of disease.

  1. Up to third relapse for whom all standard or life-extending therapies have failed and for whom no potentially curative therapies are available or who are intolerant to such therapies.
  2. Without prior myeloproliferative neoplasm (MPN) or MDS/MPN (including leukemic transformation of MPN, "blast phase", and "accelerated phase" MPN), and without hyperproliferative disease requiring cytoreductive treatment within 4 weeks from the screening or with WBC above ULN at screening.
  3. Exceptions to minimum CD123 expression are not allowed. 4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. 5. Life expectancy of at least 3 months in the judgment of the investigator. 6. Adequate renal and hepatic laboratory assessments. 7. Adequate cardiac function. 8. Long-term central venous access existing (e.g., tunneled CV catheter or port-system) or willing to have such a device inserted to ensure continuous R-TM123 administration.

9. Able to give written informed consent. 10. Weight is greater than the minimum weight required for a specific batch to ensure that the dose administered does not exceed 10^5 TCR+ cells/kg of patient weight.

11. Negative pregnancy; routinely using a highly effective method of birth control.

  1. Acute promyelocytic leukemia (t15;17) or myeloproliferative neoplasm (MPN) per WHO 2022 diagnostic criteria.
