Frequently asked questions about HEC585

What is HEC585 used for?

HEC585 is an investigational small molecule being developed for the treatment of Idiopathic Pulmonary Fibrosis (IPF), a chronic lung disease. It is also studied in healthy volunteers for safety and pharmacokinetic trials. The drug is not yet approved and is currently in clinical development.

Who makes HEC585?

HEC585 is being developed by Sunshine Biopharma Inc., a company listed on the stock exchange under the ticker SBFM. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with Idiopathic Pulmonary Fibrosis.

What phase is HEC585 in?

HEC585 is in Phase 3 clinical development. A confirmatory Phase 3 study (NCT07082842) is currently recruiting patients with Idiopathic Pulmonary Fibrosis in China. Earlier Phase 1 and Phase 2 trials have been completed or are active, but the drug remains investigational.

What clinical trials is HEC585 in?

HEC585 is being studied in several clinical trials. A Phase 3 confirmatory study (NCT07082842) is recruiting IPF patients in China. A Phase 2 study (NCT05060822) is active but not recruiting. Completed Phase 1 trials include NCT03092102 and NCT05468346, which evaluated safety and pharmacokinetics.

Is HEC585 FDA approved?

HEC585 is not FDA approved. It is an investigational drug currently in clinical development, with an ongoing Phase 3 trial in China for Idiopathic Pulmonary Fibrosis. The drug has not completed the regulatory approval process and remains under study.
