New combo aims to fight relapsed leukemia after transplant
NCT ID NCT05772273
First seen Jun 25, 2026 · Last updated Sep 03, 2026 · Updated 3 times
Summary
This study tests a combination of a PD-1 inhibitor (camrelizumab), a chemotherapy drug (azacitidine), and donor immune cells (DLI) in 43 adults with acute myeloid leukemia that has returned after a stem cell transplant. The goal is to see if this approach can help patients achieve remission again. The trial is currently recruiting participants aged 18 to 60 with adequate organ function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Camrelizumab (PD-1 inhibitor), azacitidine, and donor lymphocyte infusions
- What this could lead to
- If successful, this combination could offer a new treatment option for patients whose AML returns after a stem cell transplant, potentially improving remission rates.
- What could go wrong
- This is a small, early-phase study with only 43 participants, so results may not apply widely. The combination also carries risks like graft-versus-host disease and immune-related side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients with a diagnosis of AML relapse after allogeneic hematopoietic stem cell transplantation. 2. Adequate organ function. 3. Be able to understand and sign informed consent. 4. Age 18 to 60 years old. 5. Serum pregnancy test for females of childbearing potential that is negative within one week prior to initiation of first dose of treatment. Female patients of childbearing potential and sexually active males must agree to use a highly effective method of contraception throughout the study and for at least 90 days after the last dose of assigned treatment. 6. ECOG performance status ≤ 1. 7. Known HLA-matched donor without contraindications to donate. 8. Life expectancy \> 3 months. Exclusion Criteria: 1. Diagnosis of anther malignant disease. 2. Suspected or proven acute or chronic GVHD. 3. Proven central nervous system leukemia. 4. Prior treatment with anti-PD-1, anti-PD-L1, or DLI. 5. HLA loss positive. 6. Known active viral infection with known human immunodeficiency virus (HIV) or viral hepatitis type B (HBV) or C (HCV) or Corona Virus Disease 2019(COVID-19); 7. Uncontrolled systemic fungal, bacterial, or viral infection. 8. Known or suspected hypersensitivity to PD-1 inhibitor or azacytidine. 9. Participation in another clinical study within 3 months. 10. Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of study procedures.
