Frequently asked questions about Arhalofenate

What is Arhalofenate used for?

Arhalofenate is an investigational small molecule being studied for the treatment of gout and hyperuricemia. It has been evaluated in Phase 2 clinical trials for reducing serum uric acid levels and preventing gout flares in patients with gout. It is not approved for any indication.

What does Arhalofenate target?

Arhalofenate targets SLC22A12 (also known as URAT1) and PPARG (peroxisome proliferator-activated receptor gamma). It acts as an inhibitor of these targets. SLC22A12 is a urate transporter involved in renal uric acid reabsorption, while PPARG is a nuclear receptor that regulates metabolic and inflammatory pathways.

Who is developing Arhalofenate?

Arhalofenate is being developed by Gilead Sciences, Inc. (ticker: GILD). The company has sponsored Phase 2 clinical trials evaluating the drug in gout and hyperuricemia.

What phase is Arhalofenate in?

Arhalofenate is in Phase 2 clinical development. It has completed three Phase 2 trials, with no active trials currently listed. The drug remains investigational and has not been approved by the FDA for any indication.

What clinical trials is Arhalofenate in?

Arhalofenate has been studied in completed Phase 2 trials including NCT02252835, which evaluated it in combination with febuxostat for hyperuricemia in gout patients; NCT02063997, which assessed efficacy and safety for preventing flares and reducing serum uric acid; NCT01416402, an open-label safety and efficacy study with febuxostat; and NCT01399008, which tested MBX-102 with allopurinol in gout patients.
