Fulgent Genetics, Inc. (NASDAQ: FLGT) (“Fulgent” or the “Company”), a technology-based company with established laboratory services and therapeutic development businesses, today announced it presented updated data in the Head and Neck Cancer Track during the American Society of Clinical Oncology (ASCO) 2026 Annual Meeting Rapid Oral Abstract Session, scheduled from 4:30 p.m. to 6:00 p.m. CDT in Hall D1 at McCormick Place in Chicago.

The abstract, entitled “FID-007 in combination with cetuximab in recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC), Abstract #6020,” will present updated preliminary data from the Company’s open-label, randomized Phase 2 study (NCT06332092). The study is evaluating the efficacy of two dosing regimens and characterizing the pharmacokinetics, safety, and tolerability of FID-007 in combination with cetuximab in patients whose disease progressed following PD-1 based immune checkpoint inhibitor therapy. As of the April 16, 2026, data cutoff, FID-007 demonstrated meaningful clinical activity and a manageable safety profile in combination with cetuximab in this target patient population.

The presentation slides with updated data will be available on Fulgent’s investor relations website at the conclusion of the presentation on June 1, 2026.

Dr. Guilherme Rabinowits, one of the study’s Principal Investigators and a Senior Member in the Department of Head and Neck-Endocrine Oncology at Moffitt Cancer Center, said: “Patients with R/M HNSCC who progress after anti PD-1 based therapy lack an established, best second-line standard of care. In this setting, preliminary data showed encouraging clinical activity and a manageable safety profile for FID-007 in combination with cetuximab. The objective response rate was 61.9%, median progression-free survival was 6.7 months, median duration of response was 7.4 months, and one-year overall survival was 63.4%. Additionally, this combination showed activity in both human papilloma virus-related and -unrelated head and neck squamous cell carcinoma.” A Phase 3 study is planned.
