Spruce Biosciences, Inc. (Nasdaq: SPRB), a late-stage biopharmaceutical company focused on developing and commercializing novel therapies for rare endocrine disorders with significant unmet medical need, today reported financial results for the year ended December 31, 2022 and provided corporate updates.

“In 2022, we made significant progress across the board heading into 2023, which we believe will be a pivotal year for Spruce,” said Javier Szwarcberg, M.D., M.P.H., Chief Executive Officer of Spruce Biosciences. “In 2023, we remain focused on delivering data for a number of our ongoing clinical programs, including topline data from our CAHmelia-203 study in adult classic congenital adrenal hyperplasia (CAH), which surpassed 50% enrollment.”

Dr. Szwarcberg continued, “We’ve had a very strong start to the year. In January, we announced a strategic collaboration and exclusive license agreement with Kaken Pharmaceutical (Kaken) to develop and commercialize tildacerfont for CAH in Japan. In February, we closed a private placement financing with top-tier healthcare investors for gross proceeds of $53.6 million, which, together with the Kaken upfront payment of $15.0 million, enables us to fund operating and capital expenditures into the first half of 2025, beyond topline results for CAHmelia-204 which are anticipated in the second half of 2024.”

Recent Corporate Updates

• CAHmelia-203 in Adult Classic CAH Surpasses 50% Enrollment: Spruce surpassed 50% enrollment in the company’s CAHmelia-203 clinical study and is on track to report topline data in the second half of 2023. CAHmelia-203 is a randomized, double-blind, placebo-controlled, dose-ranging study evaluating the safety and efficacy of tildacerfont in adult patients with classic CAH and highly elevated levels of androstenedione (A4) on their current glucocorticoid regimen.
• Private Placement Financing of $53.6 million with Top-Tier Healthcare Investors: In February 2023, the company entered into a definitive securities purchase agreement for a private placement that resulted in gross proceeds of $53.6 million, before deducting commissions and offering expenses. The private placement included participation from new and existing investors, including 5am Ventures, Abingworth, Armistice Capital, HealthCap, Novo Holdings A/S, RiverVest Venture Partners, and Rock Springs Capital. The proceeds from the financing, together with the $15.0 million upfront payment due to the company under the license agreement with Kaken, is expected to allow the company to fund operating and capital expenditures into the first half of 2025.
• Strategic Partnership and Exclusive Licensing Agreement with Kaken Pharmaceutical: In January 2023, Spruce and Kaken entered into an exclusive license agreement for the development and commercialization of Spruce’s product candidate, tildacerfont, for the treatment of CAH in Japan. Under the terms of the agreement, Spruce will receive an upfront payment of $15.0 million from Kaken and will be eligible to receive additional payments upon the achievement of future development and commercial milestones, as well as tiered double-digit royalties on net sales in Japan. Kaken will be responsible for the clinical development and commercialization of tildacerfont in Japan, and Spruce will retain all rights to tildacerfont in all other geographies.
