Continuation Trial Summary

This trial is testing a new drug, MT1621, for safety and efficacy in people with a deficiency in the TK2 protein. The trial will compare measurements taken before treatment with dC/dT (a similar drug) to those taken after treatment with MT1621.

Who is the study for?
This trial is for patients with TK2 deficiency who have a confirmed genetic mutation in the TK2 gene, are not pregnant or breastfeeding, agree to use contraception, and can maintain their current treatment and exercise regimens. They must not have liver disease or certain other medical conditions that could affect study results.Check my eligibility
What is being tested?
The safety and effectiveness of two drugs, doxecitine and doxribtimine, are being tested in individuals with thymidine kinase 2 (TK2) deficiency. This Phase 2 trial is open-label, meaning both researchers and participants know which treatment is given.See study design
What are the potential side effects?
While specific side effects aren't listed here, common ones may include reactions at the injection site, fatigue, nausea or digestive issues. Participants will be monitored closely for any adverse effects throughout the study.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Does this research project represent a pioneering effort?

"Presently, 9 ongoing trials for MT1621 are in progress across 5 nations and 10 urban areas. Initially launched by GenVivo, Inc., the Phase 1 trial of 122 patients was completed back in 2014; since then, 4 more studies have been executed."

Answered by AI

Are there any vacancies remaining in this clinical trial?

"Unfortunately, this trial is not presently looking for candidates. Initially posted on July 5th 2019 and latest updated October 3rd 2022, the research team are no longer accepting applications at present. For those searchng for other studies, there is one thymidine kinase clinical trials with active recruitment and 9 MT1621 trials recruiting participants."

Answered by AI

Are there any other experiments involving MT1621 that have been conducted?

"Currently, 9 clinical trials involving MT1621 are in progress with none yet reaching Phase 3. These studies primarily take place in Buffalo, New york but span 26 distinct sites."

Answered by AI

Is MT1621 a secure medication for human consumption?

"Our team at Power gauged the safety of MT1621 as a 2. This is due to its status as a Phase 2 trial, which indicates preliminary evidence of safety but not effectiveness."

Answered by AI

How many individuals are enrolled in the experiment?

"At this time, no additional participants are being sought for the trial posted 7/5/19 and last updated 10/3/2022. However, if you are seeking alternative studies involving thymidine kinase there is currently one open study recruiting patients; additionally, 9 different clinical trials utilizing MT1621 need to be filled with volunteers."
