  • repaglinide — DRUG
    0.5 mg repaglinide tablet administered orally on Pre-Cycle Day 1 and Cycle 1 Day 14
  • midazolam — DRUG
    2 mg/mL midazolam oral solution administered orally on Pre-Cycle Day 1 and Cycle 1 Day 14
  • drospirenone — DRUG
    3 mg drospirenone tablet administered orally on Pre-Cycle Day 1 and Cycle 1 Day 10

Study Details

This drug-drug interaction (DDI) study aims to evaluate the impact of pelabresib at steady-state plasma concentrations on the pharmacokinetic (PK) profile of A) a single dose of repaglinide and a single dose of midazolam, and B) a single dose of combined drospirenone and ethinyl estradiol. The study will be conducted in adult participants with advanced malignancies for whom no standard or curative treatment options are available.

Arms

  • Experimental: Arm A
    Part 1 (PK profiles of victim drugs): • Arm A: repaglinide + midazolam + pelabresib Part 2 (Continued treatment): After completing Part 1, in case of clinical benefit, participants can continue with pelabresib treatment in Part 2 until the end of study (EOS) is reached or until the participant meets discontinuation criteria, or until they receive pelabresib treatment via alternative means of access, whichever occurs first.
  • Experimental: Arm B
    Part 1 (PK profiles of victim drugs): • Arm B: drospirenone + ethinyl estradiol + pelabresib Part 2 (Continued treatment): After completing Part 1, in case of clinical benefit, participants can continue with pelabresib treatment in Part 2 until the end of study (EOS) is reached or until the participant meets discontinuation criteria, or until they receive pelabresib treatment via alternative means of access, whichever occurs first.

Primary Outcome Measure

Maximum Plasma Concentration (Cmax) of repaglinide, midazolam, and drospirenone and ethinyl estradiol [ Time Frame: Arm A: Pre-Cycle Day 1/Cycle 1 Day 14 (Predose, 0.25-12 hours); Cycle 1 Days 1/15 (24 hours). Arm B: Pre-Cycle Day 1/Cycle 1 Day 10 (Predose, 0.5-10 hours); Days 2/11 (24 h), 3/12 (48 h), 4/13 (72 h), 5/14 (96 h); Cycle 1 Days 1/15 (120 h). 21-day cycle. ]
