New Drug Application (NDA) Filing for Tildacerfont in Adult Classic CAH Targeted for 2023

SAN FRANCISCO--(BUSINESS WIRE)--Mar. 22, 2021-- 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 fourth quarter and full year ended December 31, 2020 and provided a corporate update.

“2020 was a transformative year for Spruce Biosciences, as we firmly established our company as an emerging leader in the development of groundbreaking therapies for rare endocrine disorders,” said Richard King, Chief Executive Officer, Spruce Biosciences. “The initiation of our CAHmelia program in adult classic congenital adrenal hyperplasia (CAH) moves us one step closer to changing the treatment paradigm for patients living with this chronic and potentially life-threatening disease. Following the completion of our upsized IPO in October 2020, we are also preparing to expand the utility of tildacerfont through studies in children with classic CAH and in women living with a rare form of polycystic ovary syndrome (PCOS), with Phase 2 programs in both indications on track to initiate in the second half of 2021. We also remain focused on clinical study execution: we have the majority of our CAHmelia study sites now active across 2 continents and are encouraged by the level of patient interest registered with our study investigators and at CAHstudy.com.”

King continued, “Following discussions with U.S. Food and Drug Administration, we have decided to increase the open label extension period for CAHmelia-203 by 18 weeks and for CAHmelia-204 by 24 weeks. In addition, we have increased the size of CAHmelia-204 from 60 patients to 90 patients. We believe that these changes will result in a more robust data package. With these program enhancements, together with the impact of the ongoing COVID-19 pandemic, we now expect primary data from CAHmelia-203 in the first half of 2022 and CAHmelia-204 in the second half of 2022. Assuming positive study outcomes, we continue to target an NDA filing for tildacerfont in adult classic CAH in 2023.”

Recent Operating Highlights

Presentation of Phase 1 and 2 Data of Tildacerfont at Endocrine’s Society’s 2021 Annual Meeting (ENDO 2021): In March 2021, data from the company’s Phase 1 and 2 programs of tildacerfont in classic CAH were presented at ENDO 2021. The presentation highlighted several datasets, including data from the company’s SPR001-202 study, which demonstrated the ability of tildacerfont to reduce and normalize key disease biomarkers over a 12-week period. Normalization of highly elevated hormones in classic CAH patients over a 12-week study and without increases to daily steroid doses has not been reported to date with any other investigational product candidate.
Submission of Pediatric Investigation Plan (PIP) to the European Medicines Agency (EMA): Spruce has submitted a PIP to the Pediatric Committee of the EMA regarding a registrational program in pediatric classic CAH.
Patent Issuance Extends Tildacerfont Exclusivity Through 2038: In December 2020, the United States Patent and Trademark Office issued US Patent Number 10,849,908 titled “Corticotrophin releasing factor antagonists.” This newly issued patent covers broad claims regarding the use of a CRF1 receptor antagonist for the treatment of CAH, builds on existing composition of matter patents, and further extends exclusivity through 2038.
Addition to Russell 2000®, 3000®, and Microcap® Indexes: In December 2020, the company was added to the Russell 2000®, 3000®, and Microcap® indexes as part of Russell’s quarterly additions of selected initial public offering (IPOs). The additions increase overall awareness and visibility of the company within the investment community and may broaden its institutional shareholder base.
Amended Debt Facility with Silicon Valley Bank (SVB) Provides Access to $25 Million in Non-Dilutive Financing: The company has amended its debt facility with SVB to increase the aggregate principal amount of the term loan commitment by SVB from $4.5 million to $30 million. The amendment refinances and delays repayment of principal of the existing $4.5 million term loan to 2023 and provides access up to $25 million in additional non-dilutive financing for general corporate purposes.
Cash and Cash Equivalents of $157.2 Million at 2020 Year End: Following the IPO in October 2020, the company is well capitalized to advance its pipeline through major milestones, including primary data readout from its late-stage CAHmelia program and Phase 2 programs in pediatric classic CAH and a rare form of PCOS.

Anticipated Upcoming Milestones

Filing of an Investigational New Drug (IND) application in the first half of 2021 in PCOS
Initiation of a Phase 2 proof-of-concept clinical trial in the second half of 2021 in PCOS
Initiation of a Phase 2 clinical program in pediatric classic CAH in the second half of 2021

Financial Highlights

Cash and Cash Equivalents: Cash and cash equivalents as of December 31, 2020, were $157.2 million.
Research and Development (R&D) Expenses: R&D expenses for the fourth quarter and full year ended December 31, 2020 were $5.8 million and $23.9 million compared to $2.8 million and $10.8 million for the same periods in 2019, respectively. The overall increase in R&D expenses was primarily related to the advancement of tildacerfont into late-stage clinical development.
General and Administrative (G&A) Expenses: G&A expenses for the fourth quarter and full year ended December 31, 2020 were $2.5 million and $5.6 million, compared to $0.3 million and $2.3 million for the same periods in 2019, respectively. The overall increase in G&A expenses was primarily driven by an increase in costs related to operation as a public company.
Net Loss: Net loss for the fourth quarter and full year ended December 31, 2020 was $8.3 million and $29.5 million, compared to $3.2 million and $13.1 million for the same periods in 2019, respectively.
