On track to initiate FORTIFI-HN01, a pivotal Phase 2/3 trial of ficerafusp alfa in 1L R/M HNSCC

Completed upsized initial public offering, raising approximately $362 million in gross proceeds, with full exercise of the underwriters' option to purchase additional shares

Strong financial position with approximately $521 million in cash and cash equivalents expected to fund operations into the first half of 2029

BOSTON, Nov. 12, 2024 (GLOBE NEWSWIRE) -- Bicara Therapeutics Inc. (Nasdaq: BCAX), a clinical-stage biopharmaceutical company committed to bringing transformative bifunctional therapies for patients with solid tumors, today announced financial results for the third quarter ended September 30, 2024 and provided a business update.

"The third quarter of 2024 was momentous for Bicara, highlighted by the successful completion of our upsized initial public offering, providing us with a robust balance sheet to continue to advance the development of ficerafusp alfa, our bifunctional EGFR/TGF-β inhibitor designed to exert potent anti-tumor activity directly within the tumor microenvironment,” said Claire Mazumdar, PhD, MBA, Chief Executive Officer of Bicara Therapeutics. "We are currently on track to achieve several anticipated milestones, most notably the upcoming initiation of FORTIFI-HN01, a pivotal Phase 2/3 trial of ficerafusp alfa, for the treatment of recurrent/metastatic head and neck squamous cell carcinoma, following encouraging interim Phase 1/1b data and alignment with the FDA on the registrational trial design. Bolstered by our strong financial position with cash runway expected to fund operations into the first half of 2029, we are committed to bringing ficerafusp alfa to patients with head and neck squamous cell carcinoma and other solid tumors as quickly as possible.”

Pipeline Highlights

Bicara is developing ficerafusp alfa, a first-in-class, dual-action bifunctional epidermal growth factor receptor (EGFR)/transforming growth factor beta (TGF-β) antibody for multiple different solid tumor cancer types.

Planned Pivotal Phase 2/3 Clinical Trial in 1L R/M HNSCC

• The Company has aligned with the U.S. Food and Drug Administration on the design of FORTIFI-HN01, a pivotal Phase 2/3 trial of ficerafusp alfa in combination with pembrolizumab in 1L (first line) recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) and expects to initiate the trial late in the fourth quarter of 2024 or early in the first quarter of 2025.

• In an ongoing Phase 1/1b trial, ficerafusp alfa in combination with pembrolizumab has demonstrated clinically meaningful anti-tumor activity, with a 64% overall response rate, 18% complete response rate and median progression free survival of 9.8 months in frontline human papillomavirus (HPV)-negative R/M HNSCC, along with a favorable tolerability profile, as of the April 2024 data cut-off date (presented at the 3rd Hawaii Global Summit on Thoracic Malignancies in June 2024).
• Updated data from an ongoing Phase 1/1b trial is expected at a medical meeting in the first half of 2025.

• Data from a Phase 1b expansion cohort evaluating ficerafusp alfa in combination with pembrolizumab in second line (2L) or later squamous cancer of the anal canal is expected at a medical meeting in the first quarter of 2025.
• Updated data from a Phase 1b expansion cohort evaluating ficerafusp alfa monotherapy in 2L or later cutaneous squamous cell carcinoma is expected at a medical meeting in the first half of 2025.

• In September 2024, Bicara completed its initial public offering (IPO) of 20,125,000 shares of its common stock at a public offering price of $18.00 per share, including full exercise of the underwriters' option to purchase additional shares, raising gross proceeds of approximately $362 million, before deducting underwriting discounts, commissions and other offering expenses. Shares began trading on the Nasdaq Global Market under the symbol "BCAX.”
• In conjunction with its IPO in September 2024, Bicara appointed its President and Chief Operating Officer, Ryan Cohlhepp, PharmD, as a Director to its Board of Directors.
• In August 2024, Bicara expanded its Board of Directors with the appointments of biopharma industry leaders Mike Powell, PhD, as Chairman of the Board, and Christopher Bowden, MD, as a Director.

• Cash Position: As of September 30, 2024, Bicara had cash and cash equivalents of $520.8 million, compared to $230.4 million as of December 31, 2023. Based on its current operating and development plans, the Company expects that its existing cash and cash equivalents will fund operations into the first half of 2029.
• Research and Development Expenses: Research and development expenses were $15.9 million for the third quarter of 2024, compared to $6.9 million for the third quarter of 2023. The increase was primarily due to additional costs associated with the Company's ongoing clinical trials to advance ficerafusp alfa.
• General and Administrative Expenses: General and administrative expenses were $4.8 million for the third quarter of 2024, compared to $2.6 million for the third quarter of 2023. The increase in general and administrative expenses was primarily due to additional personnel costs and professional fees to prepare Bicara to operate as a public company.
• Net Loss: Net loss was $17.5 million for the third quarter of 2024, compared to $22.8 million for the third quarter of 2023. Net loss for the third quarter of 2023 included a $13.3 million non-cash expense that represents the change in fair value of Bicara's Series B preferred stock tranche rights liability.

Bicara Therapeutics is a clinical-stage biopharmaceutical company committed to bringing transformative bifunctional therapies to patients with solid tumors. Bicara's lead program, ficerafusp alfa, is a bifunctional antibody that combines two clinically validated targets, an epidermal growth factor receptor (EGFR) directed monoclonal antibody with a domain that binds to human transforming growth factor beta (TGF-β). Through this dual-targeting mechanism, ficerafusp alfa has the potential to exert potent anti-tumor activity by simultaneously blocking both cancer cell-intrinsic EGFR survival and proliferation, as well as the immunosuppressive TGF-β signaling within the tumor microenvironment. Ficerafusp alfa is being developed in head and neck squamous cell carcinoma, where there remains a significant unmet need, as well as other solid tumor types.
