Announced Strategic Collaboration with HMNC Brain Health GmbH (HMNC) to Develop Tildacerfont for the Treatment of Major Depressive Disorder (MDD)

Topline Data from CAHmelia-204 Study of Tildacerfont in Adult Congenital Adrenal Hyperplasia (CAH) Anticipated in Q4 2024

Topline Data from CAHptain-205 Study of Tildacerfont in Adult and Pediatric CAH Anticipated in Q4 2024

Cash Runway Through the End of 2025

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Aug. 12, 2024-- Spruce Biosciences, Inc. (Nasdaq: SPRB), a late-stage biopharmaceutical company focused on developing and commercializing novel therapies for endocrine and neurological disorders with significant unmet medical need, today reported financial results for the second quarter ended June 30, 2024 and provided corporate updates.

“We remain committed to advancing the development of tildacerfont and opening a new chapter in the management of CAH with a potentially life-changing medicine for patients and their families,” said Javier Szwarcberg, M.D., M.P.H., Chief Executive Officer of Spruce. “In the fourth quarter of 2024, we plan to report primary efficacy and safety data through week 24 plus interim data from the open-label extension of the CAHmelia-204 study, which is assessing glucocorticoid (GC) reduction, a potentially registrational endpoint in adult CAH patients on supraphysiologic GC doses with normal or near normal levels of androstenedione (A4).”

Dr. Szwarcberg added, “At the same time, we will also report topline data from CAHptain-205, which will include week 4 efficacy and safety measures on 200mg twice-daily (BID) and 400mg BID doses of tildacerfont in adults, adolescents and children with CAH and elevated levels of A4. Following our analysis of results from the CAHmelia-203 study, which evaluated doses of tildacerfont up to 200mg once-daily (QD) in adults with CAH and highly elevated levels of A4, we believe that tildacerfont has the potential to address severe hyperandrogenemia in CAH at higher doses taken BID. If results from CAHmelia-204 and CAHptain-205 are positive, we intend to meet with the U.S. Food and Drug Administration (FDA) and comparable foreign regulatory authorities to align on the next steps for our CAH program.”

Corporate Updates

• Announced Strategic Collaboration with HMNC to Develop Personalized Treatment for MDD: Spruce entered into a license, development and option agreement with HMNC to develop Spruce’s investigational product candidate, tildacerfont, a second-generation CRF₁ receptor antagonist, with HMNC’s companion diagnostic, the proprietary Cortibon Genetic Selection Tool (Cortibon), as a personalized medicine with potential for the treatment of MDD. Under the terms of the agreement, HMNC will fund and conduct a Phase 2 proof-of-concept study of tildacerfont in MDD patients, who will be screened using Cortibon. Spruce has an option to in-license exclusive worldwide rights to Cortibon after completion of the study, if results are positive.

• Poster Highlighting Final Results from Phase 2 POWER Study of Tildacerfont for the Treatment of Polycystic Ovary Syndrome (PCOS) Presented at ENDO 2024 Annual Meeting: Ricardo Azziz, M.D., M.B.A., M.P.H., Professor, Obstetrics and Gynecology at University of Alabama at Birmingham School of Medicine, presented final results from the Phase 2 POWER study, which demonstrated the ability of tildacerfont to reduce dehydroepiandrosterone sulfate levels over 12 weeks in women with PCOS. Additionally, an observed increase in serum sex hormone binding globulin demonstrated that tildacerfont may potentially lower levels of free, bioactive sex hormones such as testosterone. Tildacerfont was well-tolerated, with no safety signals observed. The majority of adverse events were mild to moderate, and no serious adverse reactions were reported. The poster presentation is available on the company’s website.

• Poster Highlighting Impact of Geography and Insurance on Healthcare Utilization Preferences of Individuals with CAH Presented at ENDO 2024 Annual Meeting: Prasanth Surampudi, M.D., Associate Professor, Endocrinology, Diabetes and Metabolism at U.C. Davis School of Medicine, presented findings related to the need for increased partnership between primary care physicians and endocrinologists as well as increased education among CAH patients and advocacy groups of specialty care to improve biochemical outcomes that reduce risks of morbidity and mortality in adult CAH patients. The poster presentation is available on the company’s website.

• Poster Highlighting Pediatric and Adult Endocrinology Practices to Improve Biochemical Outcomes in Adults with CAH Presented at ENDO 2024 Annual Meeting: Wenyu Huang, M.D., Ph.D., Associate Professor, Division of Endocrinology, Metabolism and Molecular Medicine at Northwestern University Feinberg School of Medicine, and Amir Hamrahian, M.D., Associate Professor of Medicine, Division of Endocrinology, Diabetes and Metabolism at Johns Hopkins University, presented findings exploring the risks associated with CAH diagnosis and treatment, including health impacts of hyperandrogenemia and serious adverse events with long-term use of supraphysiologic GC doses. The poster presentation is available on the company’s website.

Anticipated Upcoming Milestones

• Topline results from the CAHmelia-204 clinical trial of tildacerfont 200mg QD in adult classic CAH patients on supraphysiologic doses of GCs with normal or near normal levels of A4 anticipated in the fourth quarter of 2024

• Topline results from the CAHptain-205 clinical trial of tildacerfont 200mg BID and 400mg BID adult and pediatric cohorts anticipated in the fourth quarter of 2024

• End of Phase 2 (EOP2) meeting with the U.S. FDA anticipated in the first half of 2025

Second Quarter 2024 Financial Results

• Cash and Cash Equivalents: Cash and cash equivalents as of June 30, 2024 were $69.7 million. Cash and cash equivalents are expected to allow the company to fund its current operating plan through the end of 2025.

• Collaboration Revenue: Collaboration revenue was $1.6 million and $3.6 million for the three and six months ended June 30, 2024, respectively, compared to $2.2 million and $4.1 million for the same periods in 2023. The collaboration revenue reflects the partial recognition of the $15.0 million upfront payment the company received in April 2023 in connection with the collaboration and license agreement with Kaken Pharmaceutical.

• Research and Development (R&D) Expenses: R&D expenses for the three and six months ended June 30, 2024 were $8.1 million and $18.4 million, respectively, compared to $13.1 million and $24.8 million for the same periods in 2023. The overall decrease in R&D expenses was primarily driven by the decrease in clinical development and manufacturing expenses related to the termination of the CAHmelia-203 study, completion of enrollment in the company’s CAHmelia-204 study, and completion of the Phase 2 POWER study in PCOS.

• General and Administrative (G&A) Expenses: G&A expenses for the three and six months ended June 30, 2024 were $3.6 million and $7.9 million, respectively, compared to $3.0 million and $6.5 million for the same periods in 2023.

• Total Operating Expenses: Total operating expenses for the three and six months ended June 30, 2024 were $11.6 million and $26.3 million, respectively, compared to $16.1 million and $31.3 million for the same periods in 2023.
