Brief Summary:

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.


Condition or disease Intervention/treatment Phase
Myelodysplastic Syndromes (MDS) Combination Product: Alvocidib Plus Decitabine or Azacitidine Phase 1 Phase 2

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 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 1-hour IV infusion.

Expansion at MTD Once the MTD or preliminary RP2D of alvocidib administered as a 1 hour IV infusion is determined, up to 25 patients will be enrolled in an Expansion cohort to receive alvocidib following either decitabine or 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 1-hour 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.

Official Title: 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
Actual Study Start Date : August 29, 2018
Estimated Primary Completion Date : February 2023
Estimated Study Completion Date : June 2023


Arm Intervention/treatment
Experimental: Ph 1b and 2: MDS
  • Patients with previously untreated MDS
  • Patients with MDS who have received <6 cycles of HMAs
  • Patients with de novo (cause unknown) or secondary MDS (treatment-related) who are not eligible for intensive induction chemotherapy or stem cell transplant

    • All French-American-British (FAB) subtypes
    • Intermediate and above per IPSS-R groups
Combination Product: Alvocidib Plus Decitabine or Azacitidine

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 1-hour 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 1-hour IV infusion determined in the Ph1b study to explore efficacy of alvocidib when administered in sequence after decitabine or azacitidine.





Primary Outcome Measures :
  1. PHASE 1b: Incidence of dose-limiting toxicities (DLTs) and treatment emergent adverse events. [ Time Frame: 28 days ]
    DLTs as observed in Cy 1. Must be at least possibly related to alvocidib. Any Gr 4 nonhematologic toxicity. Gr 3 nonhematologic toxicity that does not resolve to ≤Gr 2 in 48 hours. Gr 3 diarrhea, mucositis, nausea, or vomiting will be considered dose limiting only if resolution to ≤Gr 2 requires >7 days. ≥Grade 3 creatinine elevation that does not resolve to <G2 within 7 days. Myelosuppression will not be considered in evaluating DLTs in patients except where bone marrow hypoplasia occurs for >42 days with bone marrow (BM) cellularity ≤5% and no evidence of MDS/leukemia.

  2. PHASE 2: Objective response rate using revised International Working Group (IWG) criteria (2006) [ Time Frame: 3 months ]
    Baseline disease assessment performed at screening and subsequent response assessments


Secondary Outcome Measures :
  1. PHASE 1b: Complete Response Rate (CRR: CRR: complete response [CR] / complete response with incomplete blood count recovery [CRi] / CRmarrow / partial response [PR] / hematologic improvement [HI]) [ Time Frame: 3 months ]
    Baseline disease assessment performed at screening and subsequent response assessments

  2. PHASE 2: Decitabine or Azacitidine treatment effect on BH3 profiling results in peripheral blood to find the correlation between the rate of CR/CRi/CRmarrow/PR/HI and BH3 profiling by flow cytometry with an emphasis on MCL-1 dependence. [ Time Frame: 3 months ]
    Assessment of BH3 profiling in peripheral blood
