Official title

A Randomized, Double-Blind, Dose-Finding, Placebo Controlled, Phase II Multicenter Study of Tetrodotoxin in the Treatment of Chemotherapy Induced Neuropathic Pain

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Chemotherapy-induced peripheral neuropathy (CIPN) is a major dose-limiting side effect of many chemotherapeutic agents including vincristine, paclitaxel, cisplatin, oxaliplatin, bortezomib and ixabepilone. Chemotherapy-induced peripheral neuropathy commonly occurs in greater than 40% of patients. To improve the peripheral neuropathy, the chemotherapy dosing is often either decreased or discontinued potentially affecting tumor responsiveness, prognosis, and survival. There is an unmet medical need for treatment of cancer patients with chemotherapy induced neuropathic pain (CINP) and the proposed study will investigate the efficacy and safety of multiple dose levels of tetrodotoxin (TTX) versus placebo in moderate to severe neuropathic pain caused by chemotherapy.
