Amtagvi Commercial Launch
Strong U.S. Commercial Growth and Execution with Approvals Pending in New Global Markets

• Best-in-class Amtagvi real-world response rates are increasing adoption and strengthening referral trends toward earlier treatment.
• An oral presentation at the 2026 Tandem Meetings of the American Society for Transplantation and Cellular Therapy (ASTCT®) and the Center for International Blood and Marrow Transplant Research (CIBMTR®) reported:
  • An unprecedented overall objective response rate (ORR) of ~44%.
  • Higher ORR of 52% after two or fewer prior lines of therapy, highlighting the importance of early treatment.
• A continuously growing and maturing network of U.S. authorized treatment centers (ATCs) expanded patient access in 2025, with further acceleration anticipated in 2026.
  • Academic ATCs are contributing to growth as new centers onboard and experienced centers treat more patients.
  • The first community ATCs began treating patients in late 2025 and are expected to drive additional demand in 2026.
  • A specialty pharmacy distribution channel was introduced as another option for ATCs to purchase Amtagvi.
• Five-year analysis of the C-144-01 trial of Amtagvi demonstrated ~31% ORR, median duration of response (mDOR) of 36+ months, and ~20% five-year overall survival, highlighting the unprecedented long-term benefits of this first-in-class therapy.
• Manufacturing turnaround improved to 32 days or less from inbound to return shipment to ATCs.
• Global expansion of Amtagvi is underway in several markets outside the U.S.
  • Amtagvi was approved in Canada in August 2025.
  • Regulatory submissions are under review with potential approvals in the United Kingdom and Australia in the first half of 2026, and Switzerland in the first half of 2027.
  • Iovance is working with the European Medicines Agency (EMA) to resubmit a marketing authorization application (MAA) in 2026.

Lifileucel in Previously Treated Advanced NSCLC: IOV-LUN-202 Registrational Trial
Clinical and Regulatory Momentum Building Towards Potential 2H27 Launch

• The U.S. FDA granted Fast Track Designation (FTD) for lifileucel for the treatment of adults with metastatic nonsquamous (NSQ) NSCLC that has progressed on or after chemo- and anti-PD-1 therapies and at least one line of FDA-approved targeted therapy, if indicated, for actionable tumor mutations excluding ALK, ROS1 and EGFR.
• Positive interim data demonstrated a potential best-in-class profile in NSQ advanced NSCLC patients.
  • The ORR was 26% and mDOR was not reached at 25+ months of follow up following one-time lifileucel monotherapy.
  • Standard of care docetaxel has shown 12.8% ORR, 5.6 months mDOR, and 12.3 months overall survival, highlighting a significant unmet medical need.²
• Anticipated milestones:
  • Present updated data at a major medical meeting in 2026.
  • Complete enrollment in 2026.
  • Support a supplemental Biologics License Application for U.S. accelerated approval with a potential launch in the second half of 2027.

Pipeline Updates
New Data Across Several Pipeline Programs Anticipated Throughout 2026

• Iovance announced positive early data for one-time lifileucel treatment in patients with advanced undifferentiated pleomorphic sarcoma (UPS) or dedifferentiated liposarcoma (DDLPS) who were refractory to at least one prior line of systemic therapy:
  • Among the first six evaluable patients, the confirmed RECIST v1.1 ORR was 50%.
  • Iovance plans to commence a single arm registrational trial in previously treated advanced UPS and DDLPS in the second quarter of 2026 and engage with the FDA on a path to expedited approval.
• The Phase 3 TILVANCE-301 trial of lifileucel and pembrolizumab in frontline advanced melanoma made significant progress, with enrollment accelerating across a broad and expanding global footprint. The U.S. FDA previously granted FTD in frontline advanced melanoma for lifileucel in combination with pembrolizumab. The TILVANCE-301 trial is designed with FDA and EMA input to show contribution of components for lifileucel in combination with pembrolizumab compared to pembrolizumab alone.
• Two of Iovance’s Phase 2 trials, IOV-END-201 and IOV-MEL-202, are investigating lifileucel in previously treated patients with advanced endometrial cancer and melanoma, respectively.
• A Phase 1/2 trial is investigating IOV-4001, a PD-1 inactivated TIL therapy, in previously treated advanced melanoma and NSCLC.
• A Phase 1/2 trial is investigating IOV-3001, a second-generation, modified IL-2 analog for use in the TIL treatment regimen.
• An Investigational New Drug (IND) submission is planned in the first half of 2026 to begin clinical development of IOV-5001, a genetically engineered, inducible, and tethered interleukin-12 TIL therapy, in a Phase 1/2 basket trial. 
• Multiple investigator-sponsored clinical trials are exploring new solid tumor indications for Iovance TIL therapies and next generation approaches.
