Frequently Asked Questions

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

Is this medical trial the first of its kind?

"VX-445 has a long research history, with the first study sponsored by Vertex Pharmaceuticals Incorporated occurring in 2015. This initial trial included 1044 patients. After this successful Phase 3 drug approval, there are now 22 active trials for VX-445 taking place across 110 cities and 23 countries."

Answered by AI

What other medical research has included VX-445 in their experimental treatments?

"22 studies are ongoing that involve VX-445. Of these, 15 are Phase 3 trials. The majority of the trials for VX-445 is based in Bochum and California; however, there are 1038 total locations running this kind of study."

Answered by AI

What are VX-445's benefits in treating patients?

"VX-445 is frequently used to treat those who have the homozygous for f508del mutation in the cftr gene. It can also be effective in treating conditions like cystic fibrosis (cf), ivacaftor-responsive cftr mutation, and others that fall under the category of cystic fibrosis."

Answered by AI

What is the most recent update on VX-445's journey to FDA approval?

"VX-445 is in Phase 3 of clinical trials, so it has received a score of 3 for safety. This means that while the medication is still being tested, there is some data supporting both its efficacy and safety."

Answered by AI

Could you please tell me how many patients are included in this experiment?

"Unfortunately, patient recruitment for this study has already ceased. The trial was initially announced on October 9th, 2018 but the most recent update was on July 26th, 2022. There are presently 432 other clinical trials involving cystic fibrosis and 22 for VX-445 that are still admitting patients if you are interested in participating in research."
