Ongoing clinical Trial - TTX-CINP-202

TTX-CINP-202 is a randomized, phase 2 clinical trial evaluating the safety and effectiveness of TTX vs placebo in people with established neuropathy due to their chemotherapy. Participants are expected to complete laboratory exams (blood work) and questionnaires to evaluate eligibility, safety, and quality of life. If eligible, participants will receive 8 doses of TTX or placebo over 4 days and be followed for 90 days for safety and effectiveness. TTX-CINP-202 is enrolling up to 222 people who have Chemotherapy Induced Neuropathic Pain (CINP) due to a Platinum or Taxane based chemotherapy regimen. Participants may be assigned to either an active treatment arm or the control arm of the trial.

TTX-CINP-202 is enrolling at sites based in the United States, Canada, South Korea, and Taiwan. A current list of trial sites can be found at (
