• The data cutoff date for this preliminary analysis was September 25, 2025.
• 39 patients with R/M HNSCC were randomized, with 36 having received at least one dose of study treatment.
• The objective response rate (ORR) for the 75 mg/m2 arm was 44%, and for the 125 mg/m2 arm was 59%, resulting in an overall ORR of 51% among 35 evaluable patients.
• The median progression-free survival (PFS) was 9.2 months for the 75 mg/m2 arm and 7.8 months for the 125 mg/m2 arm, with an overall PFS of 7.8 months.
• FID-007 demonstrated a favorable safety and tolerability profile, with a 6% overall treatment-related serious adverse event (SAE) rate in 36 patients evaluated for safety.
• Overall grade 3 and worse treatment-related adverse events were observed in less than 5% of patients, including lymphocyte count decreased (19%), neutrophil count decreased (17%), anemia (8%), dermatitis acneiform (8%), white blood cell count decreased (8%), rash (6%), hypomagnesaemia (6%), and pneumonia (3%).
• Grade 1-2 peripheral neuropathy was reported in 31% of patients, with no grade 3 or above peripheral neuropathy reported to date.
• An optimal dose of FID-007 will be determined after data maturation to support further development of this combination therapy.

Sentiment

Score: 8

Explanation: The preliminary Phase 2 data for FID-007 shows meaningful anticancer efficacy and a significantly improved progression-free survival compared to historical standard-of-care, coupled with a favorable safety profile. This represents a strong positive development for the company's therapeutic business.

Positives

• Meaningful anticancer efficacy demonstrated by FID-007 combined with cetuximab at both dose levels for 1L-2L treatment of R/M HNSCC.
• High overall objective response rate (ORR) of 51% when both arms are combined, with 59% for the 125 mg/m2 arm and 44% for the 75 mg/m2 arm.
• Significantly extended overall median progression-free survival (PFS) of 7.8 months, compared to the historical 2.3 months for standard-of-care therapies.
• Favorable safety and tolerability profile, with a low 6% overall treatment-related serious adverse event (SAE) rate.
• Low incidence of overall grade 3 and worse treatment-related adverse events (less than 5% of patients).
• No grade 3 and above peripheral neuropathy reported, with only 31% of patients experiencing grade 1-2.
• The precision diagnostics business continues to provide strong momentum as the primary driver of revenue.

Negatives

• No specific negative financial or operational results were reported in this filing.
• Some adverse events were noted, such as lymphocyte count decreased (19%), neutrophil count decreased (17%), and grade 1-2 peripheral neuropathy (31%), which are common side effects in cancer treatments.

Risks

• Uncertainty regarding Fulgent Pharma's research and development efforts and the expected availability of data or results from these trials.
• No implication that interim or preliminary data will be representative of final or future results, as the preliminary data is subject to change and future analysis.
• Risks related to the market potential for, and the rate and degree of market adoption of, the Company's tests, including its Beacon787 panel.
• Ability to maintain turnaround times and otherwise keep pace with rapidly changing technology.
• Ability to maintain the low internal costs of the business model and an acceptable margin.
• Risks related to volatility in results, which can fluctuate significantly from period to period.
• Risks associated with the composition of the customer base, which can fluctuate and be comprised of a small number of customers accounting for a significant portion of revenue.
• Level of success in obtaining coverage and adequate reimbursement and collectability levels from third-party payors for tests and testing services.
• Level of success in establishing and obtaining the intended benefits from partnerships, strategic investments, joint ventures, acquisitions, or other relationships.
• Success of development efforts, including the ability to progress candidates through clinical trials on the timelines expected and that initial or preliminary results will be representative of future or final results.
• Compliance with the various evolving and complex laws and regulations applicable to the business and industry.
• Ability to protect proprietary technology and intellectual property.

Future Outlook

The Company aims to transform from a diagnostic business into a fully integrated precision medicine company. An optimal dose of FID-007 will be determined after data maturation to support further development of this combination therapy. Fulgent Pharma is focused exclusively on perfecting drug candidates for treating a broad range of cancers.

Management Comments

• "We believe this preliminary data reinforces our mission to build a holistic platform that delivers comprehensive solutions across the cancer care continuum from early detection, diagnostics, and monitoring to drug discovery and development." Ming Hsieh, Chairman and CEO of Fulgent Genetics and co-founder of Fulgent Therapeutics.
• "We are encouraged by the steady advancement of FID-007 in oncology indications to date, while our precision diagnostics business continues to provide strong momentum as the primary driver of revenue for Fulgent." Ming Hsieh.

Industry Context

The development of novel therapies for recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) addresses a significant unmet medical need, as historical standard-of-care therapies have limited efficacy. The use of nanoencapsulation technology (FID-007) to improve pharmacokinetics and reduce toxicity of existing drugs like paclitaxel represents an innovative approach in oncology drug development, aligning with broader industry trends towards targeted and less toxic cancer treatments. The company's strategy to integrate diagnostic and therapeutic development positions it within the growing precision medicine sector.

Comparison to Industry Standards

• The overall median progression-free survival (PFS) of 7.8 months for FID-007 combined with cetuximab significantly exceeds the historical 2.3 months reported for standard-of-care therapies in R/M HNSCC, representing a substantial improvement in efficacy.

Stakeholder Impact

• Shareholders: Positive impact due to promising clinical trial results, potentially increasing the value of the therapeutic pipeline and future revenue streams.
• Patients with R/M HNSCC: Potential for a new, more effective, and better-tolerated treatment option.
• Medical Community: New data contributes to the understanding and treatment strategies for R/M HNSCC.
• Employees: Positive morale and potential for continued growth in the therapeutic development business.

Next Steps

• Determine an optimal dose of FID-007 after data maturation.
• Support further development of the FID-007 combination therapy.
• Continue research and development efforts for Fulgent Pharma's drug candidates.

Key Dates

Recommendation

The preliminary Phase 2 data for FID-007 in R/M HNSCC is exceptionally strong, demonstrating a significantly improved median progression-free survival (7.8 months vs. 2.3 months historical standard-of-care) and a high objective response rate (51% overall) with a favorable safety profile. This data de-risks the therapeutic pipeline considerably and suggests a high probability of success in later-stage trials, potentially leading to a blockbuster drug. The market often undervalues early-stage biotech assets, and this positive clinical readout could be a major catalyst for share price appreciation. The combination of strong efficacy and safety, coupled with the company's existing diagnostics business providing revenue, makes this an attractive investment opportunity.
