Assessment of the Safety, Tolerability and Pharmacokinetics of AV078 in Healthy Volunteers

PHASE1RECRUITING

This Phase 1 study in healthy adult volunteers is planned to evaluate the safety, tolerability, and pharmacokinetics (PK) of AV078, a selective inhibitor of mammalian target of rapamycin complex 1 (mTORC1). The study will begin with a standard exploration of safety and tolerability in sequential single ascending dose (SAD) and multiple ascending dose (MAD) cohorts. Subsequent cohorts will collect PK data to evaluate food effects and potential drug-drug interactions relevant to AV078.

Study details:

This Phase 1 study in healthy adult volunteers is planned to evaluate the safety, tolerability, and pharmacokinetics (PK) of AV078, a selective inhibitor of mammalian target of rapamycin complex 1 (mTORC1). The study will additionally explore the relationship between AV078 and pharmacodynamic biomarkers related to mTOR. The study will begin with a standard exploration of safety and tolerability in sequential single ascending dose (SAD) and multiple ascending dose (MAD) cohorts, incorporating reviews by a dedicated Safety Review Group to guide dose escalation decisions.

The study will also include a cohort using a 2-way crossover design to evaluate food effects on the PK of AV078. The study will additionally include cohorts evaluating potential drug-drug-interactions (DDIs) using coadministration of index substrates and index perpetrators typically used in DDI studies of the relevant enzymes. Specifically, one DDI cohort will assess the effects of administration of itraconazole (a strong inhibitor of CYP3A4) on the PK of AV078, and an additional DDI cohort will assess the effects of administration of AV078 on the PK of midazolam (a sensitive probe substrate for CYP3A4) and fexofenadine (a probe substrate for P-gp).

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

How is the study designed?

Participant Group/Arm	Intervention/Treatment
EXPERIMENTAL: AV078 In part A, a single ascending doses of AV078 oral solution will be investigated in separate cohorts. The starting dose will be 0.5 mg and ascending doses will be determined based on data from previous cohorts. In Part B, multiple ascending doses of AV078 oral solution will be administered once daily for 14 days. Dose levels will be determined based on data from the single ascending dose study and previous cohorts in the multiple ascending dose study. In Part C the effect of food (fasting or high calorie) on the pharmacokinetics of a single dose of AV078 will be investigated. The dose will be determined from Part A of the study.	DRUG: AV078 Oral solution containing active ingredient, AV078
PLACEBO_COMPARATOR: Placebo In Part A, placebo oral solution (containing no active ingredient) will be administered once. In Part B, placebo oral solution (containing no active ingredient) will be administered once daily for 14 days.	DRUG: Placebo Oral solution with no active ingredients
OTHER: Itraconazole In Part D, 200 mg itraconazole will be administered as an oral capsule once daily for 9 days, to investigate the effect of itraconazole on the pharmacokinetics of AV078.	DRUG: Itraconazole Once daily oral dose of 200 mg itraconazole administered for 9 days
OTHER: Midazolam and fexofenadine In Part E, 2.5 mg midazolam will be administered as an oromucosal solution and 120 mg fexofenadine will be administered as an oral tablet on day 1 and day 18, to investigate the effect of AV078 on the pharmacokinetics of midazolam and fexofenadine.	DRUG: Midazolam 2.5 mg midazolam administered orally on day 1 and day 18
