Quarterly Revenue Growth of 13% to ~$68 Million 

Gross Margin Increased to 43% on Improved Execution and Operational Efficiency

Best-in-Class Clinical Profile for Lifileucel in Previously Treated Advanced Non-Small Cell Lung Cancer (NSCLC) with Median Duration of Response Not Reached after 25+ Months Follow Up

SAN CARLOS, Calif., Nov. 06, 2025 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a commercial biotechnology company focused on innovating, developing, and delivering novel polyclonal tumor infiltrating lymphocyte (TIL) therapies for patients with cancer, today reported third quarter and year-to-date 2025 financial results, business achievements, pipeline progress, and corporate updates.

Frederick Vogt, Ph.D., J.D., Interim President and Chief Executive Officer of Iovance, stated, “We continued to see revenue growth with significant gross margin improvement in the third quarter of 2025. Amtagvi demand is increasing as we integrate our community treatment centers to drive earlier treatment and better outcomes for patients. We are building a successful commercial business, while advancing our high value development programs to address significant unmet medical needs in patients with solid tumor cancers.”

Third Quarter Financial Highlights
Topline Growth, Significant Margin Improvement, and Initial Benefits of Cost Optimization

• Total product revenue grew 13% over the prior quarter to ~$68 million, including U.S. Amtagvi revenue of ~$58 million and global Proleukin revenue of ~$10 million.
• Gross margin of 43% from cost of sales of ~$39 million reflected improved execution and the initial benefits of cost optimization. Additional operational excellence initiatives are underway to drive further near- and long-term improvements.
• Cash and cash equivalents, investments, and restricted cash totaled ~$307 million as of September 30, 2025. The current cash position, bolstered by expense reductions, is expected to fund operations into the second quarter of 2027.
• Full-year 2025 revenue guidance is reaffirmed within the range of $250 to $300 million in the first full calendar year of Amtagvi sales.
• Centralizing manufacturing at the Iovance Cell Therapy Center (iCTC) in early 2026 will reduce external manufacturing expenses and continue to improve gross margins.

Amtagvi U.S. Launch  
Strong Commercial Execution Across Growing Academic and Community Treatment Networks

• More than 80 U.S. authorized treatment centers (ATCs) have been activated across nearly 40 states, providing a broad network within a two-hour drive for ~95% of Amtagvi patients.
• Community ATCs have treated their first Amtagvi patients, with growth acceleration expected in future quarters.
• More community ATCs are being opened, which is expected to further drive demand.
• Increased awareness of treatment benefits from real-world evidence data is driving earlier Amtagvi adoption and improved referral trends among medical oncologists.
• A number of initiatives are underway to broaden patient access to Amtagvi, including a specialty pharmacy agreement with InspiroGene by McKesson.
• Manufacturing turnaround time continues to improve with a current average of 32 days from inbound to return shipment to ATCs.

Amtagvi Global Expansion
Opportunity to Address up to 30,000 Patients Globally with Previously Treated Advanced Melanoma¹

• In August 2025, Health Canada granted the first Amtagvi approval outside the U.S. for patients with previously treated advanced melanoma.
• Potential approvals of Amtagvi are anticipated in the United Kingdom and Australia in the first half of 2026 and Switzerland in 2027.
• Iovance is finalizing a strategy with the European Medicines Agency (EMA) to support EU marketing authorization for Amtagvi.

Pipeline Progress and Anticipated Milestones by Program

Lifileucel in Solid Tumors

• Positive interim data from the IOV-LUN-202 clinical trial demonstrated a potentially best-in-class clinical profile for lifileucel in previously treated advanced nonsquamous NSCLC patients.
  • The objective response rate (ORR) was 26% and the median duration of response (mDOR) was not reached at more than 25 months of follow up. Updated data will be presented at a medical meeting in 2026.
  • The U.S. Food and Drug Administration (FDA) previously provided positive regulatory feedback on the IOV-LUN-202 trial design and the proposed potency assay matrix to support registration.
  • Iovance expects the IOV-LUN-202 trial to complete enrollment in 2026 and support a supplemental Biologics License Application for lifileucel in nonsquamous NSCLC, with a potential launch in 2027.
• Initial results from the IOV-END-201 clinical trial of lifileucel in previously treated advanced endometrial cancer are on track for early 2026.
• The TILVANCE-301 clinical trial is active at more than 75 clinical sites and continues to accrue patients to investigate lifileucel in combination with pembrolizumab in frontline advanced melanoma. The trial is designed with FDA and EMA input to show contribution of components compared to pembrolizumab alone.
• A new potentially registrational clinical trial, designated IOV-MEL 202, will investigate lifileucel in advanced melanoma patients previously treated with anti-PD-1 therapy, primarily outside the U.S. The trial includes outpatient use of Amtagvi in the community setting and will enroll a subgroup of true second-line BRAF mutation positive patients without prior BRAF inhibitor therapy.

Next Generation Programs

• Clinical results for IOV-4001, a PD-1 inactivated TIL cell therapy, in previously treated advanced melanoma patients are anticipated in the first quarter of 2026. Other potential indications for IOV-4001 are also in development.
• Dose escalation is continuing for IOV-3001, a second-generation, modified IL-2 analog for use in the TIL therapy treatment regimen. Preclinical studies of IOV-3001 demonstrated the potential for improved safety, convenience of less frequent dosing and strong effector T cell expansion. Advancement into Phase 2 development is expected in 2026.
• An Investigational New Drug (IND) submission is planned in early 2026 for IOV-5001, a genetically engineered, inducible, and tethered interleukin-12 TIL therapy, in solid tumor cancers with large patient populations and urgent unmet medical.
