About

The purpose of this study is to assess the effect of PC14586 pharmacokinetics when co administered with itraconazole in healthy participants.

Full description

PC14586 is a first-in-class, oral, small molecule p53 reactivator that is selective for the TP53 Y220C mutation.

This is a Phase 1, open-label, fixed-sequence study to investigate the effect of coadministration of itraconazole on the pharmacokinetics (PK) of PC14586 (rezatapopt) in healthy male and female participants. Potential participants will be screened to assess their eligibility to enter the study within 56 days prior to the first dose administration. Participants will be admitted into the study site on Day -1 and be confined to the study site until discharge on Day 33. Participants will return to the study site for PK sample collection on Day 37 and a follow-up visit and PK sample collection on Day 42.

Approximately 16 participants will be enrolled in this study.

Enrollment: 12 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

3. History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs.
4. Participant has blood pressure >140 mmHg systolic or >90 mmHg diastolic at screening or Day -1.

11. Participation in a clinical study involving last administration of an investigational drug (new chemical entity) in the past 30 days prior to dosing, or within 5 half-lives of the IMP, whichever is longer, or have previously received PC14586.
12. Participant has a history of alcohol or drug/chemical abuse within 2 years prior to check-in and/or is unwilling to avoid use of caffeine or alcohol or caffeine-containing foods or alcohol-containing foods, medications, or beverages, within 48 hours prior to check-in until the follow up visit.
13. Use of tobacco- or nicotine-containing products (cigarettes, snuff, chewing tobacco, cigars, pipes, vaporizer, or nicotine-replacement products such as nicotine chewing gum and nicotine patches) within 3 months prior to check-in, or positive cotinine at screening or check-in.
