What is DESF used for?

DESF is an investigational small molecule being developed for the treatment of allergic reactions, including oral allergy syndrome. It is currently in clinical development and has not been approved by the FDA. Studies have been conducted in adults and pediatric subjects to evaluate its pharmacokinetics, pharmacodynamics, and safety.

Who makes DESF?

DESF is being developed by Aquestive Therapeutics, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol AQST. The company is conducting clinical trials to evaluate the drug's safety and pharmacokinetics in patients with allergic reactions.

What phase is DESF in?

DESF is in Phase 2 clinical development. Two clinical trials have been completed, including a Phase 2 study in adults with oral allergy syndrome and a Phase 1 study in pediatric subjects. The drug remains investigational and is not yet approved for commercial use.

What clinical trials is DESF in?

DESF has been studied in two completed clinical trials. NCT06527937 was a Phase 2 pharmacokinetics study in 36 adults with oral allergy syndrome in the United States. NCT07703982 was a Phase 1 study evaluating pharmacokinetics, pharmacodynamics, and safety in 32 pediatric subjects aged 7 years and older in the United States and Canada.

How does DESF work?

DESF is a small molecule designed to treat allergic reactions. Its specific molecular target has not been disclosed in available information. Clinical trials have focused on evaluating its pharmacokinetics, pharmacodynamics, and safety in patients with allergic conditions, including oral allergy syndrome.
