Key Terms

series b financing, urat1 inhibitor, phase 3, registration-directed trials
4 terms
series b financing financial
"closed an oversubscribed $130 million Series B financing"
Series B financing is a later-stage investment round where outside investors provide significant capital in exchange for an ownership stake to help a private company scale operations, add staff, expand into new markets, or accelerate product development. For investors, a Series B is a sign the business has passed early proof points but needs more funding to grow; it affects the company’s valuation and existing owners’ stakes much like a growing shop taking a larger loan to open multiple new locations.
urat1 inhibitor medical
"a next-generation, once daily, oral URAT1 inhibitor"
A urat1 inhibitor is a drug that blocks a specific protein in the kidneys that normally reclaims uric acid back into the bloodstream; by stopping that “recycling” it helps the body excrete more uric acid and lowers blood levels. For investors, these drugs matter because they address conditions driven by high uric acid (like gout and related kidney issues), so their clinical success, safety and regulatory approval can affect market opportunity, revenue potential and valuation of companies developing them.
phase 3 medical
"two ongoing Phase 3 registration-directed trials"
Phase 3 is the late-stage clinical testing step for a new drug or medical treatment, where the product is given to large groups of patients to confirm effectiveness, monitor side effects, and compare it to standard care. Successful Phase 3 results are often the final scientific hurdle before regulators decide on approval and market launch—like passing a final exam before graduation—and can sharply change a company's valuation and future revenue prospects.
registration-directed trials regulatory
"Phase 3 registration-directed trials, RUBY and TOPAZ"
Clinical studies planned and conducted specifically to provide the evidence a regulatory agency requires for product approval or licensure. Like a final exam designed to meet a school’s graduation rules, these trials use predefined endpoints, patient populations and statistical plans meant to demonstrate safety and effectiveness to regulators; their outcomes strongly influence whether a product can be marketed and therefore affect a company’s future revenue prospects.

Proceeds to support ongoing late-stage global clinical development and commercialization preparation of dotinurad, a next-generation, once daily, oral URAT1 inhibitor with the potential to deliver best-in-class safety and efficacy for the treatment of gout

MIAMI, July 27, 2026 (GLOBE NEWSWIRE) -- Urica Therapeutics, Inc. (“Urica” or the “Company”), a Fortress Biotech, Inc. (Nasdaq: FBIO) (“Fortress”) subsidiary, today announced that Crystalys Therapeutics, Inc. (“Crystalys”), in which Urica maintains an equity position, closed an oversubscribed $130 million Series B financing to support the late-stage global clinical development and commercialization preparation for dotinurad, a next-generation, once daily, oral URAT1 inhibitor for the treatment of gout.

Dotinurad's clinical development program includes two ongoing Phase 3 registration-directed trials, RUBY and TOPAZ, as well as the ongoing Phase 2 AMETHYST study, collectively designed to evaluate dotinurad across a broad spectrum of patients with gout, including those with limited treatment options. The proceeds from the financing are expected to support ongoing clinical development of dotinurad, commercialization preparation activities and provide operational runway through multiple anticipated clinical and regulatory milestones.

Lindsay A. Rosenwald, M.D., Fortress’ Executive Chairman, President and Chief Executive Officer, said, “This financing supports the advancement of global pivotal trials and paves the way toward regulatory approval and commercialization for dotinurad in the United States and Europe, potentially bringing a new treatment option to the millions of people living with gout. In addition to its clinical promise, this transaction strengthens the position of Fortress and our subsidiary Urica, through Urica’s equity stake in Crystalys and royalties tied to dotinurad's future commercialization.”

Crystalys acquired dotinurad from Urica in 2024, and Urica currently holds a minority equity position in Crystalys and is eligible to receive a 3% royalty on future net sales of dotinurad. Urica is a majority-owned and controlled subsidiary of Fortress.
