Spruce Biosciences Reports First Quarter 2022 Financial Results and Provides Corporate Update

SAN FRANCISCO--(BUSINESS WIRE)-- 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 first quarter ended March 31, 2022 and provided corporate updates.

“Throughout the first quarter of 2022, we continued to drive our clinical and business objectives forward, with key progress made in our lead program for adults with classic congenital adrenal hyperplasia (CAH), expansion of our executive leadership team, and through potential access to non-dilutive sources of capital. We were pleased to achieve the recent milestone of 25% enrollment in our CAHmelia-203 study for adult classic CAH, which keeps us on track to meet topline data readout for the study in the second half of 2023,” said Javier Szwarcberg, M.D., M.P.H., Chief Executive Officer of Spruce Biosciences. “The enhanced protocols we rolled-out for the CAHmelia-203 and 204 studies have been well-received by study investigators across our global trial sites and have streamlined screening activities. We look forward to continuing this momentum and providing further enrollment updates over the course of the year.”

Recent Corporate & Pipeline Updates

• 25% Enrollment Achieved in CAHmelia-203 Study for Adult Classic CAH: Spruce Biosciences recently achieved 25% 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 is designed to enroll approximately 72 patients with high levels of androstenedione (A4) on their current glucocorticoid regimen. Study sites are now enrolling under the amended protocol, which is anticipated to accelerate patient enrollment.

• Enrollment in CAHmelia-204 Progressing Under Amended Protocol: CAHmelia-204 is a randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of tildacerfont in adult patients with classic CAH. The study is designed to enroll approximately 90 patients on supraphysiologic doses of glucocorticoids at or above 30 mg/d hydrocortisone equivalent with normal or near normal levels of A4. Study sites are now enrolling under the amended protocol, which removed the glucocorticoid conversion requirement. Enrollment is progressing as planned and the company plans to share enrollment updates over the course of the year.

• Debt Facility with Silicon Valley Bank (SVB) Amended to Provide $10 Million Credit Line in 2022: Spruce Biosciences has amended its debt facility with SVB to provide a credit line of up to $10 million (“Tranche 2”) in 2022, subject to the satisfaction of certain financial and operating conditions. The amendment also reduces the current variable interest rate on the outstanding debt of $5 million by 50 basis points and on Tranche 2 by 250 basis points. Additionally, subject to potential drawdowns under Tranche 2 occurring, the interest-only period for outstanding term debt will be extended from December 31, 2022 to June 30, 2023. No warrants were issued in connection with the amended debt facility.

• Tildacerfont Patent Portfolio Estate Expanded with Key Method of Use Patents: Spruce Biosciences continues to expand its patent portfolio for its wholly-owned product candidate tildacerfont to supplement its issued composition of matter patent and market exclusivity afforded by orphan drug designation in the United States and Europe for CAH, if approved. In April 2022, the United States Patent and Trademark Office issued U.S. Patent Number 11,304,950 titled “Methods of treating testicular and ovarian adrenal rest tumors,” and U.S. Patent Number 11,311,549 titled “Corticotropin release factor receptor antagonists.” The newly issued patents cover broad claims regarding the use of a CRF-1 receptor antagonist for the treatment of adrenal rest tumors and use of tildacerfont to reduce androstenedione in patients with CAH. These patents expand existing patent exclusivity through 2038.

• Libbie Mansell, Ph.D., M.B.A., R.A.C., Appointed Chief Regulatory and Quality Officer: In April 2022, Libbie Mansell, Ph.D., M.B.A., R.A.C. was appointed Chief Regulatory and Quality Officer of Spruce Biosciences, and will lead the company’s global regulatory affairs and quality strategy. Dr. Mansell is a seasoned regulatory affairs professional, with over 30 years of industry experience in serious and rare diseases. She joins Spruce from Asklepios BioPharmaceutical (AskBio), where she served as Senior Vice President of Regulatory Affairs.
