HM2023-05: GTB-3650 Trike for High Risk MDS and R/R AML (NCT06594445)
🩺 Plain-English Summary (8th-Grade Level)
This is a Phase I dose finding study of GTB-3650 (anti-CD16/IL-15/anti-CD33) Tri-Specific Killer Engager (TriKE®) for the treatment of select CD33-expressing refractory/relapsed myeloid malignancies in adults ≥ 18 years of age who are not a candidate for potentially curative therapy, including hematopoietic stem cell transplantation, and are refractory to, intolerant of, or ineligible for therapy options that are known to provide clinical benefit. The hypothesis is GTB-3650 TriKE will induce natural killer (NK) cell function by targeting malignant cells, as well as, CD33+ myeloid derived suppressor cells (MDSC) which contribute to a tumor induced immunosuppression. Because CD16 is the most potent activating receptor on NK cells, this single agent may induce a targeted antiCD33+ tumor response

📋 "Do I Qualify?" — 1-Minute Self Screener
Instant ChecklistCheck every box below. If you can check all of them, you may meet the study's basic screening requirements (final eligibility is confirmed by the site team).
Usually NOT eligible if any of the following apply:
- Exclusion Criteria:
- Pregnant or breast-feeding. The effect of GTB-3650 TriKE on the fetus is unknown. Persons of childbearing potential must have a negative serum or urine test within 7 days prior to Cycle 1 Day 1 to rule out pregnancy.
- A candidate for hematopoietic stem cell transplant (HSCT) or newly relapsed after HSCT (e.g. no post-HSCT therapy given).
- Bi-phenotypic acute leukemia or mixed lineage leukemia.
- Acute promyelocytic leukemia (APL).
- No anticancer therapy within 14 days of Cycle 1 Day 1; any AEs from therapy given prior must have resolved to Grade 1 or baseline
- New or progressive pulmonary infiltrates on screening chest x-ray or chest CT scan unless cleared for study by Pulmonary. Infiltrates attributed to infection must be stable/improving with associated clinical improvement after 1 week of appropriate therapy (4 weeks for presumed or documented fungal infections).
- Active systemic infection requiring parenteral antibiotic therapy. Any prior systemic infections must have resolved following optimal therapy.
- Known history of HIV.
- Active Hepatitis B or Hepatitis C (virus detectable by PCR) - chronic asymptomatic viral hepatitis is allowed.
- Positive test results from chronic hepatitis B infection (defined as positive HBsAg serology) and/or positive test results for hepatitis C (HCV antibody serology test).
- Prior malignancy except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated Stage I or II cancer currently in complete remission, or any other cancer from which the patient has been disease-free for 1 year
