Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Part A (Treatment 1) - All treatment periods will be open label. All participants will receive ONC201 (one oral capsule at each dose) in sequential, non-randomised, escalating doses of 125 mg in Period 1, 375 mg in Period 2, and 625 mg in Period 3. Only 1 single dose will be given in each period. There will be a wash out period of 1 week between each dose. All doses will be administered in the clinic. and will be administered under a fasting condition (nothing but water for at least 10 hours prior to dosing and 1 hour post dosing).

Type of endpoint/s
Pharmacokinetics
Statistical methods / analysis
PK parameters following single-dose administration will be determined using standard noncompartmental methods and actual sampling times utilizing a PK data analysis program (e.g., Phoenix WinNonlin or equivalent).
Safety will be assessed through AEs, measurement of vital signs, ECGs, neurological assessments, and clinical laboratory test results. All AEs reported and any concomitant medication intake will also be documented.
Part A
Plasma ONC201 and ONC207 (metabolite) concentrations will be listed and summarized by dose and timepoint. Individual and mean plasma and urine concentration-time profiles will be plotted. Plasma and urine ONC201 and ONC207 PK parameters will be listed and summarized by dose.
Dose proportionality in plasma ONC201 Cmax and AUCinf will be assessed; if AUCinf is not well estimated, AUClast will be used for dose proportionality assessment.
