Frequently asked questions about Colistimethate

What is Colistimethate used for?

Colistimethate is an investigational small molecule being developed for the treatment of Pseudomonas infections. It is currently in Phase 1 clinical development, meaning it has not yet been approved by regulatory authorities and remains under study to evaluate its safety and efficacy.

Who makes Colistimethate?

Colistimethate is being developed by GSK plc, a global biopharmaceutical company listed on the stock exchange under the ticker symbol GSK. The company is conducting clinical research to assess the drug's potential as a treatment for Pseudomonas infections.

What phase is Colistimethate in?

Colistimethate is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still undergoing clinical trials to evaluate its safety, tolerability, and pharmacokinetics in humans.

What clinical trials is Colistimethate in?

Colistimethate has one completed Phase 1 clinical trial registered under NCT01449838, titled 'Phase I Study of Colistin Methanesulfonate Sodium.' This randomized, double-blind, placebo-controlled study enrolled 22 healthy male volunteers in Australia and evaluated the drug's safety and tolerability.

Is Colistimethate the same as colistin methanesulfonate?

Yes, Colistimethate is also known as colistin methanesulfonate sodium, as reflected in the clinical trial title. The drug is being studied for its potential use in treating Pseudomonas infections, though it remains in early-stage clinical development.
