• Updated data from Phase 1/1b trial presented at 2025 ASCO Annual Meeting demonstrated deep and durable responses in 1L HPV-negative R/M HNSCC
• Data from additional Phase 1/1b expansion cohorts evaluating alternate dose regimens in HPV-negative patients expected by Q1 2026
• Strong financial position with approximately $437 million in cash and cash equivalents as of June 30, 2025 expected to fund operations into the first half of 2029

BOSTON, Aug. 12, 2025 (GLOBE NEWSWIRE) -- Bicara Therapeutics Inc. (Nasdaq: BCAX), a clinical-stage biopharmaceutical company committed to bringing transformative bifunctional therapies to patients with solid tumors, today announced financial results for the second quarter ended June 30, 2025 and provided a business update.

“We continue to make excellent progress with the development of ficerafusp alfa,” said Claire Mazumdar, PhD, MBA, Chief Executive Officer of Bicara Therapeutics. “Updated Phase 1/1b data recently presented at ASCO 2025 from the 1500mg weekly cohort underscore the differentiated ability of ficerafusp alfa to remodel the tumor stroma and drive tumor penetration, with deep, durable anti-tumor responses observed in HPV-negative recurrent/metastatic head and neck squamous cell carcinoma patients. These data provide a strong foundation for the continued advancement of our pivotal Phase 2/3 FORTIFI-HN01 trial, and reinforce our confidence in the study design. We also look forward to presenting data from two additional Phase 1/1b expansion cohorts evaluating alternate dose regimens in patients with HPV-negative disease, which are expected to further characterize the safety and efficacy profile of ficerafusp alfa in this population with high unmet need.”

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 designed to enhance tumor penetration by breaking barriers in the tumor microenvironment that have challenged the treatment of multiple solid tumor cancers.

FORTIFI-HN01: Pivotal Phase 2/3 Clinical Trial in 1L R/M HNSCC

Enrollment is ongoing in FORTIFI-HN01, a global, randomized, double-blind, placebo-controlled, pivotal Phase 2/3 trial of ficerafusp alfa in combination with pembrolizumab in first line (1L) recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC), excluding patients with oropharyngeal squamous cell carcinoma associated with human papillomavirus infection (HPV-positive).

Phase 1/1b Clinical Trial in 1L R/M HNSCC

• Updated data with extended follow-up from a Phase 1/1b trial evaluating 1500mg ficerafusp alfa weekly in patients with 1L R/M HNSCC was highlighted in an oral presentation at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting.
  • In the efficacy evaluable human papillomavirus (HPV)-negative population (n=28):
    • Median duration of response (DOR) of 21.7 months amongst responders (n=15).
    • Median overall survival (OS) of 21.3 months; 2-year OS rate of 46%.
    • 54% (15/28) confirmed objective response rate (ORR); 64% (18/28) ORR, including three additional unconfirmed responses and 21% (6/28) complete response rate.
    • 80% (12/15) of responders achieved a deep response (≥80% tumor shrinkage).
    • Disease control rate of 89% (25/28 patients).
    • Median progression-free survival of 9.9 months.
    • Manageable safety profile consistent with previously reported adverse events.
• Additional Phase 1b expansion cohorts evaluating ficerafusp alfa in 1L R/M HNSCC remain ongoing:
  • Data from a cohort evaluating 750mg of ficerafusp alfa weekly in combination with pembrolizumab in HPV-negative patients are expected to be presented at a medical meeting in the fourth quarter of 2025 or the first quarter of 2026.
  • Data from a cohort evaluating 2000mg of ficerafusp alfa every other week in combination with pembrolizumab in HPV-negative patients are expected to be presented at a medical meeting in the first quarter of 2026.
  • A cohort evaluating 1500mg weekly of ficerafusp alfa in combination with pembrolizumab in HPV-negative patients with combined positive scores (CPS) of 0 continues to enroll. Data from this cohort are expected to be presented at a medical meeting in 2026.

Development of Ficerafusp Alfa Across Other Solid Tumor Types

• A Phase 1b expansion cohort evaluating ficerafusp alfa both as monotherapy and in combination with pembrolizumab in patients with 3L+ metastatic colorectal cancer (RAS/B-Rapidly Accelerated Fibrosarcoma (BRAF) wild type) is enrolling.

 Second Quarter 2025 Financial Results

• Cash Position: As of June 30, 2025, Bicara had cash and cash equivalents of $436.6 million, compared to $489.7 million as of December 31, 2024. 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 $24.8 million for the second quarter of 2025 as compared to $15.8 million for the second quarter of 2024. The increase was primarily due to additional costs associated with the initiation of FORTIFI-HN01, a pivotal Phase 2/3 clinical trial, as well as the Company’s ongoing Phase 1/1b clinical trials to advance ficerafusp alfa and an increase in personnel costs.
• General and Administrative Expenses: General and administrative expenses were $7.2 million for the second quarter of 2025 as compared to $3.9 million for the second quarter of 2024. The increase was primarily due to additional personnel costs and professional fees to support advancement of our clinical trials and operations as a public company.
• Net Loss: Net loss totaled $27.4 million for the second quarter of 2025 as compared to $17.0 million for the second quarter of 2024.

About Bicara Therapeutics

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 first-in-class bifunctional antibody designed to drive tumor penetration by breaking barriers in the tumor microenvironment that have challenged the treatment of multiple solid tumor cancers. Specifically, ficerafusp alfa 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 targeted mechanism, ficerafusp alfa reverses the fibrotic and immune-excluded tumor microenvironment driven by TGF-β signaling to enable tumor penetration that drives deep and durable responses. 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.
