A Phase 1 Study of Orca-Q in Recipients Undergoing Allogeneic Transplantation for Hematologic Malignancies

What's the purpose of this trial?

This study will evaluate the safety, tolerability, and efficacy of engineered donor grafts ("OrcaGraft"/"Orca-Q") in participants undergoing myeloablative allogeneic hematopoietic cell transplant transplantation for hematologic malignancies.

This trial is currently open and accepting patients.


What will happen during the trial?

You may be able to join this trial if you:

The following criteria is a partial list of reasons why patients may be eligible to participate in this clinical trial. Further evaluation with a medical professional is required.

3. Planned to undergo myeloablative allogeneic hematopoietic stem cell transplant (HCT)
4. Matched to a 8/8 or 7/8 related or unrelated donor, or to a related haploidentical donor
5. Estimated glomerular filtration rate (eGFR) \> 50 mL/minute
6. Cardiac ejection fraction at rest ≥ 45% or shortening fraction of ≥ 27% by echocardiogram or radionuclide scan (MUGA)
7. Diffusing capacity of the lung for carbon monoxide (DLCO) (adjusted for hemoglobin) ≥ 50%
8. Total bilirubin \< 1.5 times upper limit of normal (ULN) (\< 3 times if attributed to Gilbert's syndrome) and ALT/AST \< 3 times ULN

Key Exclusion Criteria:

1. Prior allogeneic HCT
2. Currently receiving corticosteroids or other immunosuppressive therapy. Topical corticosteroids or oral systemic corticosteroid doses less than or equal to 10 mg/day are allowed.
3. Planned donor lymphocyte infusion (DLI)
4. Positive anti-donor HLA antibodies against a mismatched allele in the selected donor
5. Karnofsky performance score \< 70% (Appendix 12.7)
6. Hematopoietic cell transplantation-specific Comorbidity Index (HCT-CI) \> 4 (Appendix 12.8)
7. Uncontrolled bacterial, viral or fungal infections (currently taking antimicrobial therapy and with progression or no clinical improvement) at time of enrollment
8. Seropositive for HIV-1 or -2, HTLV-1 or -2
9. Any uncontrolled autoimmune disease requiring active immunosuppressive treatment
10. Concurrent malignancies or active disease within 1 year, except non-melanoma skin cancers that have been curatively resected
11. History of idiopathic or secondary myelofibrosis
12. Women who are pregnant or breastfeeding
