Summary
Brief summary (as posted)
This study will be divided into two parts, Parts A and B and will enroll patients with relapsed/refractory AML or MDS/chronic myelomonocytic leukemia (CMML) patients who have failed up to 2 prior therapeutic regimens. Part A is a dose escalation study to explore the safety, efficacy, pharmacokinetic (PK) and pharmacodynamic (PD) profile of DSP107 when administered in combination with azacitidine (AZA). Part B is a dose escalation study to explore the safety, efficacy, PK and PD profile of DSP107 when administered in combination with AZA and venetoclax (VEN).

- type
- EXPERIMENTAL
- label
- DSP107 in combination with azacitidine or azacitidine plus venetoclax.
- description
- DSP107 will be administered by intravenous infusion once weekly during each 28-day cycle to all patients in this study. Azacitidine (75 mg/m2/day) will be administered subcutaneously or intravenously for the first 7 days of every cycle. Patients enrolled in Part B only will also receive venetoclax. During Cycle 1, venetoclax will be dose escalated daily to the goal dose of 400 mg daily. Patients will receive 100 mg on Day 1, 200 mg on Day 2 and 400 mg on Day 3 and onwards.

- Adverse Events (AEs)
- timeFrame
- Duration of the study, estimated to be 12 months
- description
- An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
