Brief summary

The purpose of this study is to assess the safety, tolerability of the drug INCB099280 and assess how this drug acts in the body with and without food in increasing doses. You may be eligible for this study if you are a male or female, aged 18 to 55, and you are in good health with no existing conditions. Participants in this study will be randomized (by chance) in each of the 6 cohort. In Cohorts 1-5 all participants will either receive a single dose of the drug or placebo (orally in a fasted condition (no food). In Cohort 6 all participants will be randomly assigned to treatment A or treatment B groups and then crossed over to the other treatment group (A or B) after a washout of 7 days. Participants in treatment A group will be dosed after fasting of 8 hrs. Participants in treatment B group will be fed a high-fat calorie meal before 30 min of dose administration. Participants will also provide blood and urine samples. It is hoped this research will provide information as to how this drug acts in the body in fed and fasted conditions, results from the study will affect how patients with cancer use this medication.

Interventions

INCB099280 is an oral tablet administered after a fast of 8 hrs. in cohorts 1 through 5. In Cohort 6 participants will be randomly assigned to treatment A or treatment B groups and then crossed over to the other treatment group (A or B) after a washout of 7 days.

In Cohort 6 participants will be randomly assigned to treatment A or treatment B groups and then crossed over to the other treatment group (A or B) after a washout of 7 days. Participants in treatment A group will be dosed after fasting of 8 hrs. Participants in treatment B group will be fed a high-fat calorie meal before 30 min of dose administration. Participants will be admitted to the clinic on the day -1 before study drug administration and confined through 96 hours after the dosing. In Cohort 6 participants will return on Day 7 for admission and receive another dose of the drug on Day 8 and confined through 96 hours after dosing. Cohort 1 - 25 mg of INCB099280 or Placebo as a single dose administered orally in a fasted condition Cohort 2 - 75 mg of INCB099280 or Placebo as a single dose administered orally in a fasted condition Cohort 3 - 150 mg of INCB099280 or Placebo as a single dose administered orally in a fasted condition Cohort 4 - 300 mg of INCB099280 or Placebo as a single dose administered orally in a fasted condition Cohort 5 - 450 mg of INCB099280 or Placebo as a single dose administered orally in a fasted condition Cohort 6 - 150mg of INCB099280 in Fasted or Fed conditions as a single dose administered orally
