简要总结

This study will evaluate the safety, tolerability, and efficacy of Orca-T, an allogeneic stem cell and T-cell immunotherapy biologic manufactured for each patient (transplant recipient) from the mobilized peripheral blood of a specific, unique donor. It is composed of purified hematopoietic stem and progenitor cells (HSPCs), purified regulatory T cells (Tregs), and conventional T cells (Tcons) in participants undergoing myeloablative allogeneic hematopoietic cell transplant transplantation for hematologic malignancies.

入选标准

  • Recipients must meet all of the following criteria:
  • Patients must be diagnosed with 1 of the following histopathologically confirmed diseases, for which a myeloablative hematopoietic stem cell transplant (HCT) is planned:
  • A) Acute myeloid, lymphoid, or mixed phenotype/undifferentiated leukemia who are not in CR or CRi (active disease) and/or MDS with >10% to <20% bone marrow blast burden (ages 18 to 75 years)
  • B) Acute leukemia in CR/CRi or MDS that is DRI intermediate to high risk (ages 66 to 75 years)
  • C) BPDCN (ages 18 to 65 years)
  • D) Participants aged 18 to 65 who would be eligible for the Phase 3 component of Precision-T except for mild impairments of renal and/or hepatic function as defined by an eGFR of 50 to <60 mL/min and/or a total bilirubin of >ULN to ≤2 x ULN and diagnosed with either of the following:
  • i. Acute myeloid, lymphoid, or mixed phenotype/undifferentiated leukemia that is in CR/CRi and DRI intermediate to high risk
  • a) MDS that is DRI intermediate to high risk
  • E) Acute or chronic leukemia in remission that is DRI low risk (ages 18 to 65 years), including the following:
  • i. CML in chronic phase but with a history of accelerated phase or blast crisis or who are resistant to or intolerant of more than 1 first- and second-generation tyrosine kinase inhibitors
  • ii. Acute myeloid leukemia (AML) with inv(16) without accompanying complex cytogenetics
  • Patients must be matched to a 8/8 HLA-matched related or unrelated donor
  • Estimated glomerular filtration rate (eGFR) >50 mL/minute
  • Cardiac ejection fraction at rest ≥45% or shortening fraction of ≥27% by echocardiogram or radionuclide scan (MUGA)
  • Diffusing capacity of the lung for carbon monoxide (DLCO) (adjusted for hemoglobin) ≥50%
  • Total bilirubin <2 times upper limit of normal (ULN) (patients with Gilbert's syndrome may be included where hemolysis has been excluded) and ALT/AST <3 times ULN

排除标准

  • Recipients meeting any of the following exclusion criteria will not be eligible:
  • History of prior allogeneic HCT
  • Currently receiving corticosteroids or other immunosuppressive therapy. Topical corticosteroids or oral systemic corticosteroid doses less than or equal to 10 mg/day are allowed.
  • Pre-planned donor lymphocyte infusion (DLI)
  • Planned pharmaceutical in vivo or ex vivo T cell depletion
  • Positive for anti-donor HLA antibodies against an allele in the selected donor
  • Karnofsky performance score <70%
  • Hematopoietic cell transplantation-specific Comorbidity Index (HCT-CI) >4
  • Uncontrolled bacterial, viral or fungal infections (currently taking antimicrobial therapy and with progression or no clinical improvement) at time of enrollment
  • Seropositive for HIV-1 or -2 antibody, HTLV-1 or -2 antibody, Hepatitis B sAg, or Hepatitis C antibody
  • Any uncontrolled autoimmune disease requiring active immunosuppressive treatment
  • Concurrent malignancies or active disease within 1 year, except non-melanoma skin cancers that have been curatively resected
  • Women who are pregnant or breastfeeding
