Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Assess the effects of ONC201 on other ECG parameters relative to a moxifloxacin positive control and to placebo:
Change-from-baseline heart rate (HR), QTcF, PR, and QRS intervals using by-time point analysis
• Placebo-corrected change-from-baseline HR, QTcF, PR, and QRS intervals
• Categorical outliers for QTcF, HR, PR, and QRS intervals
• T-wave morphology and U-wave presence changes

Simple randomisation using a randomisation table created by computer software
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data
Intervention assignment
Crossover
Other design features
Volunteers will be randomized to one of 6 treatment sequences according to a Williams design for a 3-way crossover design with a minimum 7-day washout period between doses. Only ONC201 will be blinded with a placebo. Moxifloxacin will be administered open label.
Phase
Phase 1
Type of endpoint/s
Safety
Statistical methods / analysis
The primary analysis for Part 2 will be based on concentration-OTc modeling of the relationship between ONC201 (and its metabolite ONC207) and change-from-baseline OTcF (change OTcFl)
Safety data will be analyzed descriptively using frequencies of events or continuous statistical summaries
