Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study consists of 3 planned dose cohorts where each cohort will enrol a total of 8 participants of which 6 randomised to TP-317 treatment arm and 2 randomised to the placebo treatment arm. A total of 24 participants will be enrolled for this study.

The planned dosed cohorts are as follows:
Cohort 1 - Single oral dose of TP-317 10mg or Placebo tablets
Cohort 2- Single oral dose of TP-317 40mg or Placebo tablets
Cohort 3- Single oral dose of TP-317 80mg or Placebo tablets
Participants will be administered oral tablet(s) under fasted condition (no food or water 10 hours prior and no food for 4 hours post dose and no water for 2 hours post-dose) on Day 1 . A designated unblinded pharmacist or other qualified personnel at the clinical site will be responsible for administering the study medication
Each Cohort will be administered to a distinct group of participants and observed for 24 hours post dose before proceeding with dosing the other planned cohort participants. Safety review committee will determine to proceed with subsequent cohorts after reviewing the safety data.

Summary
Brief summary
This is a first in human Single Ascending Dose Study to Assess the Safety, Tolerability and Pharmacokinetic of TP-317 (oral tablets) under fasted conditions in Adult Healthy Volunteers.

TP-317 is being developed to address the high unmet medical need for a safe, oral therapy for chronic treatment of mild to moderate inflammatory bowel disease (IBD)

This study consists of 3 planned dose cohorts. Each cohort will enroll a total of 8 participants with 6 randomized to TP-317 treatment arm and 2 randomized to the placebo treatment arm. Safety Review Committee will review the participant safety data as needed and determine dose escalation to the next cohort.

Participants in the study will be administered oral tablet(s) under fasted conditions, defined as no food or water 10 hours prior to oral dosing.
