A Phase 1b/2 Study of Alvocidib Plus Decitabine or Azacitidine in Patients With MDS
A Phase 1b/2, Open-label Clinical Study to Determine Preliminary Safety and Efficacy of Alvocidib When Administered in Sequence After Decitabine or Azacitidine in Patients With MDS
Alvocidib, a cyclin-dependent kinase 9 (CDK 9) inhibitor, in time-sequential therapy demonstrated significant clinical activity in secondary AML patients with prior MDS. Patients with IPSS-R intermediate and above MDS have an increased risk of developing AML and may be treated with the same chemotherapy regimens used in patients with AML. Eight Phase I or II clinical trials have been completed in patients with AML, totaling more than 400 patients with both relapsed/refractory or newly diagnosed AML.
Preclinical studies have demonstrated that decitabine exposure increased the expression of NOXA, which is a specific antagonist of the survival factor MCL 1. Pharmacologic downregulation of MCL-1 via CDK 9 inhibition, as well as upregulation of the MCL-1 antagonist, NOXA, following decitabine exposure may result in enhanced antileukemic activity in MCL-1-dependent malignancies.

Detailed Description
PHASE 1b:
Patients will be enrolled in cohorts of 3-6 patients. Escalation of the alvocidib dose will follow a standard 3+3 design with sequential cohorts of 3 patients treated with incrementally higher doses of alvocidib administered in sequence after decitabine (during dose escalation) or azacitidine until a dose-limiting toxicity (DLT) is observed and the MTD is established.
Once the MTD or preliminary RP2D of alvocidib administered via hybrid dosing is identified, 2 cohorts of at least 3 patients each will receive azacitadine followed by alvocidib administered as a 30-60 minute IV infusion.
Expansion at MTD Once the MTD or preliminary RP2D of alvocidib administered as a 30-to-60 minute IV infusion is determined, up to 25 patients will be enrolled in an Expansion cohort to receive alvocidib following azacitadine to confirm safety, explore potential biomarkers, and evaluate potential signals of alvocidib activity. Once this Expansion cohort is completed, the study will progress to Phase 2
PHASE 2:
Phase 2 design is based on the Simon 2-stage minimax design (Simon 1989).
- Stage 1: Up to 15 evaluable patients will be enrolled and treated at the RP2D identified in the Phase 1b study.
- Stage 2: Ten patients will be enrolled to bring the total enrollment in Phase 2 (including Stage-1 patients) to 25 evaluable patients. Stage-2 patients will also receive the RP2D dose of alvocidib administered by 30-to-60 minute IV infusion identified in the Phase 1b study. If 6 or more responses are observed in 25 patients, the conclusion will be that the combination regimen is worthy of further investigation.

- Patients with an Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score ≤2 at enrollment
- Provide written informed consent prior to any study-related procedure. (In the event that the patient is re-screened for study participation or a protocol amendment alters the care of an ongoing patient, a new informed consent form must be signed.)
- Patients with a life expectancy of ≥3 months (90 days)
Patients with adequate major organ functions meeting the following criteria on the basis of laboratory data within 4 weeks (28 days) before enrollment (if multiple data are available, most recent data during the period):
- Serum creatinine: ≤1.8× the upper limit of the normal (ULN) range
- Total bilirubin: ≤2× the ULN
- Aspartate transaminase (AST) and alanine transaminase (ALT): ≤3× the ULN
- Left ventricular ejection fraction (LVEF) >45% by echocardiogram or multigated acquisition (MUGA) scan
- Be able to comply with the requirements of the entire study.

Presence of concomitant severe cardiovascular disease:
- Patients who had myocardial infarction within 6 months (180 days) before enrollment

PHASE 1b: Decitabine administered as an intravenous (IV) infusion daily for 5 days at a dose of 20 mg/m2 followed on Day 8 by alvocidib as a loading dose over 30 minutes followed by a 4-hour IV infusion (hybrid dosing) Once the maximum dose of alvocidib administered via hybrid dosing has been determined, 2 cohorts of patients will receive azacitidine followed by alvocidib administered as an IV infusion. Azacitidine may be administered as either an IV bolus over 10 to 40 minutes or as a subcutaneous (SC) injection on either a 7 day or 5-2 2 schedule. Regardless of which azacitidine schedule or route of administration is used, alvocidib will be given on Day 10 as a 30-to-60 minute IVI PHASE 2: The Phase 2 study will use the RP2D from the Phase 1b study and follow a Simon 2-stage minimax design using the RP2D of alvocidib administered as a 30-to-60 minute IV infusion determined in the Ph1b study to explore efficacy of alvocidib when administered in sequence after azacitidine. |
