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.

Interventions

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 plan

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.
