Study Endpoints

Primary Endpoints

Efficacy: long-term efficacy of tetrodotoxin (TTX) in reducing pain and improving quality of life. Safety: long-term safety and tolerability of s.c. TTX
Repeat treatment for patients with meaningful analgesic response
Efficacy: Composite-endpoint will be an evaluation that combines pain outcome and quality of life. Pain intensity will be used a co-primary endpoint. Safety as assessed by the analysis of AEs, 12-lead ECG, and abnormal lab values.
Dec2010
Cardiodynamic
24 hours

The primary cardiodynamic endpoint was the effect of TTX plasma concentrations on the QTc interval using linear mixed-effect exposure-response modeling, including the predicted ddQTc at Cmax values corresponding to exposure levels of interest.

Compare plasma and urine PK profiles of TTX following doses of Lyophilized and Injectable Liquid TTX
26 timepoints over 48 hours

PK timepoints occurred at 0,0.33,0.67,1, 1.5,2,4,6,8,10,12,14 and 24 hours after first dose on Days 1 \& 2. Liquid and Lyophilized formulations will be assessed using ANOVA of the T-R ratio based on log-transformed AUC and Cmax values.

Secondary Endpoints

For each Treatment Cycle: the total number of days a subject meets the definition of pain response.
Repeat treatment for subjects with meaningful analgesic response
The period of onset of pain response as reported by responders.

Frequently asked questions about Tetrodotoxin

What is Tetrodotoxin used for?

Tetrodotoxin is an investigational small molecule being developed by Dogwood Therapeutics, Inc. (DWTX) for the treatment of moderate to severe inadequately controlled cancer-related pain. It is administered subcutaneously and has been studied in clinical trials for pain management in cancer patients.

What does Tetrodotoxin target?

Tetrodotoxin is a small molecule that works by blocking sodium channels, specifically the voltage-gated sodium channels responsible for pain signal transmission. By inhibiting these channels, it aims to reduce pain signaling in patients with cancer-related pain.

Who makes Tetrodotoxin?

Tetrodotoxin is being developed by Dogwood Therapeutics, Inc., a biopharmaceutical company traded under the ticker symbol DWTX. The company is conducting clinical research to evaluate the safety and efficacy of this investigational drug for pain management.

What phase is Tetrodotoxin in?

Tetrodotoxin is currently in Phase 1 clinical development. While it has completed Phase 3 trials for cancer-related pain, the most recent studies are Phase 1 trials evaluating its cardiovascular effects and formulation comparisons in healthy volunteers. It remains investigational and is not FDA approved.

What clinical trials is Tetrodotoxin in?

Tetrodotoxin has completed four clinical trials. These include two Phase 3 studies (NCT00725114 and NCT00726011) for cancer-related pain, and two Phase 1 studies (NCT01527734 and NCT04083833) in healthy volunteers. The Phase 1 trials evaluated formulation differences and cardiovascular effects, including a TQT study.

Is Tetrodotoxin the same as TTX?

Yes, Tetrodotoxin is commonly referred to as TTX. In clinical trials, it is often identified by this abbreviation, such as in the study titled 'Comparison Study of Liquid and Lyophilized Formulations of Subcutaneous Tetrodotoxin (TTX) in Healthy Volunteers.'
