Study Summary

This trial tests drug interactions in people. Each person takes part in one part of the trial.

Who is the study for?
Healthy males aged 18-55 with normal metabolism, good general health, and no significant medical history can join. They must have normal kidney function and agree to use contraception or abstain from sex. Those with recent illness, heart issues, allergies, or on certain medications are excluded.Check my eligibility
What is being tested?
The study is testing how Pacritinib interacts with drugs that affect the CYP450 enzyme system in two parts: one part combines it with a CYP450 inducer (Bosentan), and another part combines it with a CYP450 inhibitor (Fluconazole).See study design
What are the potential side effects?
Possible side effects may include reactions related to the liver enzymes affected by the drug interactions being studied. Specific side effects will depend on how Pacritinib interacts with Bosentan or Fluconazole.

Trial Design

3Treatment groups
Experimental Treatment
Group I: CYP450 Cocktail and Transporter Substrates with PacritinibExperimental Treatment1 Intervention
This is the first part of the study which is an open-label, single-center, 1-way DDI study designed to assess the effect of pacritinib 200 mg BID at steady state on the systemic exposure of a cocktail of cytochrome P450 (caffeine, midazolam, and omeprazole) and transporter substrates (digoxin, rosuvastatin, and metformin) in 18 healthy male subjects.
Group II: CYP450 3A4 inhibitor (Fluconazole) with PacritinibExperimental Treatment1 Intervention
This is the second arm of Part 2 of the study: Days 1 through 14: An oral dose of pacritinib 200 mg (2 × 100 mg capsules) BID (approximately 12 hours apart) Days 8 through 14: An oral dose of fluconazole 200 mg QD
Group III: CYP450 3A4 inducer (Bosentan) with PacritinibExperimental Treatment1 Intervention
The second part of the study comprises of 2 arms. This is the first arm Days 1 through 14: An oral dose of pacritinib 200 mg (2 × 100 mg capsules) BID (approximately 12 hours apart) Days 8 through 14: An oral dose of bosentan 125 mg BID (approximately 12 hours apart) All the doses will be administered with approximately 240 mL of water.
