Frequently asked questions about VGA039

What is VGA039 used for in Von Willebrand Disease?

VGA039 is an investigational small molecule being developed for the treatment of Von Willebrand Disease (VWD), a bleeding disorder. It is currently in Phase 3 clinical development and has not been approved by the FDA. The drug is being studied in patients with VWD, including those aged 12 years and older.

What does VGA039 target?

VGA039 targets Protein S, a protein involved in the regulation of blood coagulation. By modulating Protein S activity, VGA039 aims to address the underlying bleeding tendency in Von Willebrand Disease. This mechanism is being evaluated in clinical trials to assess its safety and efficacy in patients.

Who makes VGA039?

VGA039 is being developed by Incyte Corporation, a biopharmaceutical company traded on the NASDAQ under the ticker symbol INCY. Incyte is conducting clinical trials to evaluate VGA039 for the treatment of Von Willebrand Disease, with studies currently in Phase 3 development.

What phase is VGA039 in?

VGA039 is currently in Phase 3 clinical development for Von Willebrand Disease. It is an investigational drug that has not received FDA approval. The drug has been granted Breakthrough Therapy, Fast Track, Orphan Drug, and Rare Pediatric Disease designations by the FDA, reflecting its potential in this indication.

What clinical trials is VGA039 in?

VGA039 is being studied in two clinical trials. NCT05776069 is a Phase 1 study in healthy volunteers and patients with Von Willebrand Disease, with an enrollment of 116 participants. NCT07115004 is a Phase 3 study evaluating subcutaneous VGA039 in patients with VWD, with an enrollment of 60 participants.

Is VGA039 the same as any other drug?

VGA039 is the sole name provided for this investigational drug. It is not known by any alternative names in the available information. The drug is being developed by Incyte Corporation and is currently in Phase 3 trials for Von Willebrand Disease.
