 the clinical trial. In preliminary safety data, Tvardi has observed similar incidence, grade and TEAEs in Cohort A treated with TTI-101 monotherapy as observed in the Phase 1 clinical trial, with diarrhea being the most commonly reported TEAE, mostly grade 1 or 2. Early safety data from the combination arms (TTI-101 + pembrolizumab (Cohort B) or TTI-101 + atezolizumab + bevacizumab (Cohort C)) of the Phase 1b portion of the clinical trial in HCC revealed a higher than expected incidence of pulmonary-related TEAEs, which are known side effects when treated with SoC. Based upon this information, and after consultations with thought leaders and investigators, the protocol was modified to explore lower dosages and intermittent schedules of TTI-101 in combination with pembrolizumab (Cohort B) or atezolizumab + bevacizumab (Cohort C).

TABLE OF CONTENTS

Preliminary efficacy is available for all three cohorts. In Cohort A, of 21 efficacy evaluable patients, 14 patients achieved a best response of SD. This disease control rate of 67% is comparable to the disease control rate (53%) observed in the HCC cohort of the Phase 1 trial of TTI-101 monotherapy. In Cohort B, four of eight patients achieved SD. Lastly, in Cohort C, out of 12 enrolled patients, four achieved a cPR with an overall disease control rate of 93%.

Based on Tvardi’s Phase 1 data and this clinical trial design, TTI-101 received Fast Track designation from the FDA. Fast Track designation may not lead to a faster development or regulatory review or approval process and does not increase the likelihood that TTI-101 will receive marketing approval.

Tvardi’s TTI-109 Product Candidate

Tvardi’s second product candidate, TTI-109, is an oral, small-molecule, prodrug of, and mechanistically identical to, TTI-101. TTI-109 itself does not inhibit STAT3, but rapidly converts to TTI-101 in the blood. TTI-109 is designed to enhance Tvardi’s ability to target STAT3 as a more efficient delivery vehicle for TTI-101 with the potential to improve tolerability.
