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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will be conducted in 2 parts:
Part A: Single ascending doses of STC-004 or placebo. Upto 5 cohorts are planned starting at 5mg and going up to maximum dose of 100mg. Participants will be administered the study drug in fasted state as an oral suspension solution followed by 250 mL of water. Study drug will be administered to the participants by the site staff while confined at the clinical site.
Part B: Multiple ascending doses of STC-004 or placebo for 10 days. Upto 3 cohorts are planned and will commence once results are available from the first 3 SAD cohorts. Dose selection and initiation of additional MAD cohorts will be based on cumulative results from the completed SAD and MAD cohorts. Participants will be administered the study drug once daily for a period of 10 days in fasted state as an oral suspension solution followed by 250 mL of water. Study drug will be administered to the participants by the site staff while confined at the clinical site.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomized to receive STC-004 or Placebo according to the randomisation schedule and plan prepared prior to study start. Code-break tamper-evident envelopes containing treatment allocation per participant will be provided to the study site for emergency unblinding if required.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants who meet the study eligibility criteria will be assigned a randomisation number pre-dose on Day 1, which corresponds to a study treatment (STC-004 or placebo). The allocation of STC-004 or placebo will be performed using a block randomization algorithm
and will be documented in the study randomization list generated by an unblinded statistician.

Summary
Brief summary
This is a double-blind, randomized, placebo-controlled study which is subdivided in 2 parts, Part A (SAD - Cohorts 1-5) and Part B (MAD - Cohorts 6-8). Decisions about how and when to move between cohorts will be based on reviews of the available blinded safety data and available pharmacokinetic (PK) data: this data will be reviewed by a prespecified Safety Review Committee (SRC). In Part A, healthy volunteers will be enrolled to receive single ascending doses of STC-004 or placebo under fasted conditions. In Part B, healthy volunteers will be enrolled to receive once daily doses of STC-004 or placebo under fasted conditions.
