Trial Description
This is a Phase 1b, open-label, multicenter study designed to evaluate the safety and
pharmacokinetics of venetoclax as a single-agent and in combination with azacitidine in
participants with relapsed/refractory Myelodysplastic Syndromes (MDS).
Eligibility Requirements
Inclusion Criteria:
- Subjects who have relapsed or refractory MDS.
- Subject enrolled in venetoclax monotherapy must have documented failure of prior
therapy with a hypomethylating agent (HMA). HMA-failure is defined as:
1. Relapse after initial complete or partial response or hematological improvement
after at least 4 cycles of azacitidine or at least 4 cycles of decitabine within
the last 5 years, OR
2. Failure to achieve complete or partial response or hematological improvement
after at least 4 cycles of azacitidine or at least 4 cycles of decitabine within
the last 5 years
- Subjects must have presence of < 20% bone marrow blasts per bone marrow
biopsy/aspirate at screening.
- Subject is not a candidate to undergo allogenic hematopoietic stem cell
transplantation (HSCT).
- Subject must have an Eastern Cooperative Oncology Group (ECOG) performance score of
≤2.
- Subject must have adequate hematologic, renal, and hepatic function.
Exclusion Criteria:
- Subject has received prior therapy with a BH3 mimetic.
- Subject has MDS evolving from a pre-existing myeloproliferative neoplasm (MPN).
- Subject has MDS/MPN including chronic myelomonocytic leukemia (CMML), atypical chronic
myeloid leukemia (CML), juvenile myelomonocytic leukemia (JMML) and unclassifiable
MDS/MPN.
- Subject has received allogeneic HSCT or solid organ transplantation.
- Subject has received a live attenuated vaccine within 4 weeks prior to the first dose
of study drug.
