Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
ONC201 (investigational drug) will be dosed, as a 125mg capsule orally, as per the following groups:
Part 1 - 3 x Healthy Volunteers will be dosed once only with ONC201 750 mg (6 capsules)
3 x Healthy Volunteers will be dosed twice, 4 hours apart with ONC201 625mg (5 capsules)
Adherence to intervention will be via mouth check of swallowed capsule
both groups will occur simultaneously and will be run in parallel both being able to be dosed the same time

Outcomes
Primary outcome [1] 331802 0
Part 1: Determine the Cmax, Tmax, AUClast, AUCinf, %AUCextrap, t1/2, CL/F, Vz/F of ONC201 administered as an oral single dose of ONC201 750 mg and as 2 oral doses of ONC201 625 mg administered 4 hours apart in healthy adult participants.
Timepoint [1] 331802 0
Plasma ONC201 PK parameters: For participants receiving the single ONC201 750 mg dose, blood samples will be collected at pre-dose (within 15 minutes prior to dosing) and at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 24, 36, and 48 hours post dose

Other design features
Part 1; Open label sentinel dosing. Randomized 1:1 to receive either a single oral dose of ONC 201 750 mg or two single oral doses of ONC201 625 mg administered 4 hours apart

Phase 1
Type of endpoint/s
Safety
Statistical methods / analysis
In this study 6 participants will be randomized, Safety data will be analyzed descriptively using frequencies of events or continuous statistical summaries for each dosing regimen.
ONC201 plasma PK parameters will be listed and summarized by treatment.
To inform the selection of the ONC201 dose/dosing schedule for Part 2 TQT study, safety and PK data from the Part 1 lead-in study will be reviewed by dosing regimen. The safest dose/dosing regimen of ONC201 that best approximates the patient Cmax and AUC values observed in patients clinically will be taken forward into Part 2.

Summary
Brief summary
The purpose of part 1 of this study is to:
• Evaluate how safe and well tolerated either a single 750mg dose or two 625mg doses of ONC201 is, in healthy participants.
• To help determine the dose level and schedule for Part 2 of the ONC201-102 study

Part 1 will enroll 6 participants to be randomized 1:1 to receive ONC201 750 mg, single dose (3 participants) or ONC201 administered as two 625 mg doses given 4 hours apart (3 participants).
Participants will be housed in the clinic on Day -1 through to Day 3.
Part 1 - will consist of a screening period of up to 28 days, in house period - Day -1 to Day 3 and a Follow up visit at Day 14 post dose.
