Frequently asked questions about RE-021, sparsentan

What is RE-021 used for?

RE-021, also known as sparsentan, is an investigational small molecule being studied for the treatment of focal segmental glomerulosclerosis (FSGS), a kidney disorder. It has also been evaluated in healthy subjects for pharmacokinetic purposes. The drug is in clinical development by Travere Therapeutics, Inc. (NASDAQ: TVTX).

How does RE-021 work?

RE-021 (sparsentan) is a small molecule that targets the endothelin and angiotensin pathways. It acts as a dual endothelin receptor antagonist and angiotensin II receptor blocker, which may help reduce proteinuria and slow kidney damage in conditions like focal segmental glomerulosclerosis.

Who is developing RE-021?

RE-021 is being developed by Travere Therapeutics, Inc., a biopharmaceutical company listed on NASDAQ under the ticker TVTX. The company is conducting clinical trials to evaluate the drug's safety and efficacy in focal segmental glomerulosclerosis and its pharmacokinetics in healthy subjects.

What phase is RE-021 in?

RE-021 has completed a Phase 2 clinical trial in focal segmental glomerulosclerosis and a Phase 1 trial in healthy subjects. It is an investigational drug and has not been approved by regulatory authorities. The Phase 2 trial was randomized, double-blind, and active-controlled, enrolling 109 participants.

What clinical trials is RE-021 in?

RE-021 has been studied in two completed trials. NCT01613118 was a Phase 2 randomized, double-blind, safety and efficacy study in focal segmental glomerulosclerosis, enrolling 109 participants in the United States, Czechia, and Italy. NCT05562362 was a Phase 1 study evaluating the pharmacokinetics of oral sparsentan suspension in 47 healthy subjects in the United Kingdom.

Is RE-021 the same as sparsentan?

Yes, RE-021 is also known as sparsentan. Clinical trials for the drug use the name sparsentan in their titles, such as NCT01613118, which is titled 'Randomized, Double-Blind, Safety and Efficacy Study of RE-021 (Sparsentan) in Focal Segmental Glomerulosclerosis.'
