Frequently asked questions about AL-794

What is AL-794 used for?

AL-794 is an investigational small molecule being developed for the treatment of influenza in humans. It is currently in Phase 1 clinical development, with studies evaluating its safety, tolerability, pharmacokinetics, and antiviral activity in healthy volunteers and in an influenza challenge model.

Who makes AL-794?

AL-794 is being developed by Vertex Pharmaceuticals Incorporated, a biopharmaceutical company traded on the NASDAQ under the ticker symbol VRTX. The company is conducting Phase 1 clinical trials to evaluate the drug's safety and pharmacokinetic profile in healthy subjects.

What phase is AL-794 in?

AL-794 is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Three Phase 1 trials have been completed, with a total enrollment of 183 participants, all conducted in the United Kingdom.

What clinical trials is AL-794 in?

AL-794 has completed three Phase 1 clinical trials: NCT02588521, a single and multiple dose study with an influenza challenge component; NCT02877160, a pharmacokinetic study of different formulations; and NCT02888327, a drug-drug interaction study with oseltamivir and JNJ-63623872. All trials were conducted in the United Kingdom.

Is AL-794 the same as oseltamivir?

No, AL-794 is not the same as oseltamivir. AL-794 is a separate investigational drug being developed by Vertex Pharmaceuticals. A completed clinical trial (NCT02888327) specifically evaluated the drug-drug interaction between AL-794 and oseltamivir, indicating they are distinct compounds that may be used together.
