• Updated data from ongoing Phase 1/1b trial in 1L R/M HNSCC to be presented at 2025 ASCO Annual Meeting
• Enrollment ongoing in FORTIFI-HN01, a pivotal Phase 2/3 trial of ficerafusp alfa in 1L R/M HNSCC
• Strong financial position with approximately $462 million in cash and cash equivalents expected to fund operations into the first half of 2029

BOSTON, May 13, 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 first quarter ended March 31, 2025 and provided a business update.

"We continued to execute across our clinical programs in the first quarter, maintaining strong momentum as we advance FORTIFI-HN01, the pivotal Phase 2/3 trial of ficerafusp alfa in HPV-negative recurrent/metastatic head and neck squamous cell carcinoma," said Claire Mazumdar, PhD, MBA, Chief Executive Officer of Bicara Therapeutics. "Near term, we look forward to presenting updated data from our ongoing Phase 1/1b clinical trial in this patient population as part of an oral presentation at the 2025 ASCO Annual Meeting. We believe the data have the potential to demonstrate differentiated depth and durability of response driven by the TGF-β arm of ficerafusp alfa. Additionally, we recently presented several datasets at AACR highlighting the broad therapeutic potential of ficerafusp alfa, including translational data that support its potential to prevent resistance mechanisms and potentially prolong durability in HPV-negative patients."

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.

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 1L (first line) 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).

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

• Updated data with extended follow-up from an ongoing Phase 1/1b trial will be highlighted in an oral presentation at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, which will be held from May 30-June 3, 2025 in Chicago, IL.
• Additional Phase 1b expansion cohorts evaluating ficerafusp alfa in 1L R/M HNSCC remain ongoing:
  • A cohort evaluating 750mg of ficerafusp alfa weekly in combination with pembrolizumab in HPV-negative patients has completed enrollment.
  • A cohort evaluating 2000mg of ficerafusp alfa every other week in combination with pembrolizumab in HPV-negative patients is enrolling.
  • A cohort evaluating 1500mg weekly of ficerafusp alfa in combination with pembrolizumab in HPV-neg patients with combined positive scores of 0 is enrolling.
  • A cohort evaluating ficerafusp alfa in combination with pembrolizumab in HPV-positive patients with a history of heavy smoking is expected to initiate in 2025.

Ongoing Phase 1/1b Expansion Cohorts and Development of Ficerafusp Alfa Across Other HNSCC Populations and Solid Tumor Types

• At the American Association for Cancer Research (AACR) Annual Meeting 2025, Bicara presented several datasets that underscore the broad therapeutic potential of ficerafusp alfa. These presentations included:
  • Preliminary findings from a translational medicine biomarker dataset from Bicara’s ongoing Phase 1/1b trial of ficerafusp alfa in 1L R/M HNSCC demonstrated that ficerafusp alfa effectively blocked TGF-β signaling and enabled tumor penetration to modulate key mechanisms associated with drug resistance.
  • Updated data from an ongoing Phase 1b expansion cohort evaluating ficerafusp alfa monotherapy in patients with second line or later cutaneous squamous cell carcinoma (cSCC) that showed continued single agent activity with an overall response rate (ORR) of 30.4% (7/23 patients) and median progression-free survival of 7.0 months (95% CI, 2.7-8.9 months), demonstrating improvements over historical treatment in cSCC.
  • New preclinical data offered insights into how TGF-β inhibition may help overcome acquired resistance to KRAS G12C inhibitors in KRAS G12C-mutant lung cancer, an important area of unmet need for patients with these types of rat sarcoma (RAS) mutations.
• 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 expected to initiate in 2025.

Upcoming Events and Presentations

• Details of Bicara’s oral presentation at 2025 ASCO Annual Meeting, which will be held from May 30-June 3, 2025 in Chicago, IL, are as follows:
  • Title: Ficerafusp alfa with pembrolizumab in patients with recurrent or metastatic head and neck squamous cell carcinoma: Updated results from an expansion cohort of an open-label, multicenter, Phase 1/1b trial
  • Abstract #: 6017
  • Session Title: Rapid Oral Abstract Session
  • Session Category: Rapid Oral Abstract Session
  • Session Date and Time: 6/1/2025 12:12 - 12:18 p.m. CT
  • Location: McCormick Place Convention Center

 First Quarter 2025 Financial Results

• Cash Position: As of March 31, 2025, Bicara had cash and cash equivalents of $462.1 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 $34.3 million for the first quarter of 2025 as compared to $12.0 million for the first 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.
• General and Administrative Expenses: General and administrative expenses were $7.5 million for the first quarter of 2025 as compared to $3.3 million for the first quarter of 2024. The increase was primarily due to additional personnel costs and professional fees to support the advancement of our clinical trials and operations as a public company.
• Net Loss: Net loss totaled $36.8 million for the first quarter of 2025 as compared to $12.5 million for the first 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 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.
