About this study
Official title: A Study of VA Combined With PD-1 Inhibitor in the Treatment of Relapsed and Refractory AML and High-risk MDS
The efficiency and safety of PD-1 inhibitor in combination with venetoclax and hypomethylation agent in relapsed/refractory acute myeloid leukemia or high-risk myelodysplastic syndrome remain uncertain. In this study, the investigators aimed to assess safety and response to a new PD-1 inhibitor-based triple-drug combination regimen (venetoclax + hypomethylation agent + PD-1 inhibitor) in relapsed/refractory acute myeloid leukemia and high-risk myelodysplastic syndrome patients, or who had positive minimal residual disease.
- Conditions
- Relapsed Acute Myeloid Leukemia, Refractory Acute Myeloid Leukemia, Myelodysplastic Syndromes, Minimal Residual Disease
- Being tested
- PD-1 inhibitor, Venetoclax, Decitabine, Azacytidine
- Keywords
- Venetoclax, Hypomethylation agen, PD-1 inhibitor
- Medical subject headings
- Leukemia, Myeloid, Acute, Myelodysplastic Syndromes, Neoplasm, Residual
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PD-1 inhibitor, Venetoclax, Decitabine, AzacytidineDrug
Also called PD-1 inhibitor (Tislelizumab), Venetoclax (ABT-199, GDC-0199), Decitabine (Dacogen, 5-aza-2-deoxycytidine), Azacitidine (5-Azacytidine, Ladakamycin)
For AML patients: PD-1 inhibitor was given at a dose of 200mg on day 21 of the treatment. Venetoclax was given at a dose of 400 mg/day for 28 days per cycle. Decitabine was given at a dose of 20 mg/m2/day for 5 days or azacytidine was given at a dose of 75 mg/m2/day for 7 days at the discretion of the treating physician.
For MDS patients: PD-1 inhibitor was given at a dose of 200mg on day 21 of the treatment. Venetoclax was given at a dose of 400 mg/day for 14 days per cycle. Decitabine was given at a dose of 20 mg/m2/day for 5 days or azacytidine was given at a dose of 75 mg/m2/day for 7 days at the discretion of the treating physician.
The venetoclax starting dose is 100 mg on the first day, ramping up to 200 mg on the second day and finally 400 mg once daily. The steady daily dose (after ramp-up phase) should be reduced to 100 mg (coadministered with moderate CYP3A inhibitors or P-gp inhibitors) and 70 mg (coadministered with strong CYP3A4 inhibitors).
| Study group | Role | What they receive |

| VA-PD1i | Experimental | Patients are treated with PD-1 inhibitor combined with venetoclax and decitabine/azacytidine. Receives: Drug: PD-1 inhibitor, Venetoclax, Decitabine, Azacytidine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Complete remission rate
percentage of subjects with complete remission (CR) and incomplete hematologic recovery (CRi)
Measured: At the end of Cycle 2 (each cycle is 28 days)
Complete minimal residual disease (MRD) Response Rate
Percentage of subjects with MRD negative or MRD < 0.01%
Measured: At the end of Cycle 2 (each cycle is 28 days)
MRD Response Rate
Percentage of subjects with MRD < 0.1% detectable by multicolor flow cytometry
Measured: At the end of Cycle 2 (each cycle is 28 days)
Secondary outcomes (4)
Relapse-Free Survival
Time interval from leukemia free state to the first recurrence or death
Measured: 24 months
Overall Survival
Time interval from start of treatment until death or last follow-up
Measured: 24 months
Duration of response
Time interval from morphologic/MRD response to loss of response or death
Measured: 24 months
Adverse events
Number of subjects with adverse events
Measured: start of treatment to 2 weeks after end of treatment
