Amtagvi (Lifileucel) U.S. Launch Highlights in Advanced Melanoma

• The U.S. FDA approved Amtagvi (lifileucel) on February 16, 2024, as the first treatment option for patients with advanced melanoma after anti-PD-1 and targeted therapy. Amtagvi is the first FDA-approved T cell therapy for a solid tumor indication.

• Onboarding is complete at 56 U.S. ATCs across 29 states and more than 90% of addressable patients are now located within 200 miles of an ATC. Approximately 70 ATCs remain on track to be onboarded by the end of 2024.

• Manufacturing turnaround time has been on target, with launch expectations of approximately 34 days from inbound to return shipment to ATCs. With efforts underway, turnaround time is expected to be reduced in the near term. The commercial manufacturing experience is consistent with prior clinical experience.

• Amtagvi is a preferred second-line or subsequent therapy in the National Comprehensive Cancer Network^® guidelines for treatment of cutaneous melanoma.

• Reimbursement remains successful, with an average financial clearance time of about three weeks.

• Approximately 75% of enrolled Amtagvi patients are covered by private payers. To date, payers or plans covering more than 250 million lives have added Amtagvi to policies since its launch.

Lifileucel Launch Expansion into New Markets

• Amtagvi has the potential to address more than 20,000 patients annually with previously treated advanced melanoma across the U.S. and multiple global markets where regulatory submissions have been submitted or are planned for 2024 and 2025.¹

• Regulatory dossiers are under review, submitted, or planned across multiple international markets for lifileucel for the treatment of adult patients with unresectable or metastatic melanoma previously treated with a PD-1 blocking antibody, and if BRAF V600 mutation positive, a BRAF inhibitor with or without a MEK inhibitor. If approved, lifileucel will be the first and only approved therapy in this treatment setting in all markets.

  • A marketing authorization application (MAA) for all EU member states was validated and accepted for review by the European Medicines Agency for potential approval in the second half of 2025.

  • An MAA was submitted to the Medicines and Healthcare products Regulatory Agency in the United Kingdom for potential approval in the first half of 2025.

  • A near-term new drug submission (NDS) was deemed eligible for Notice of Compliance with Conditions (NOC/c) by Health Canada. The NOC/c policy includes a prioritized 200-day review process for potential NDS approval in mid-2025.

  • Additional regulatory dossiers remain on track for submission in 2025 and 2026 in markets with significant populations of previously treated advanced melanoma patients, including Australia in the first half of 2025 and Switzerland in the second half of 2025.

Iovance TIL Cell Therapy Pipeline Highlights

• Lifileucel in Frontline Advanced Melanoma

  • Updated clinical data from Cohort 1A of the IOV-COM-202 trial was presented at ASCO 2024 and demonstrated an unprecedented rate, depth and durability of responses, including a 30% confirmed complete response rate, and a differentiated safety profile in advanced melanoma patients who were naive to immune checkpoint inhibitors.

  • Cohort 1D in the IOV-COM-202 trial is exploring lifileucel in combination with nivolumab and relatlimab in patients with frontline advanced melanoma, representing another potential best-in-class frontline alternative for physicians and patients in the U.S.

  • Strong momentum continues with global site activation and patient enrollment in the TILVANCE-301 trial, with nearly 50 active sites across 11 countries, including the U.S., Europe, Australia, and Canada, and more than 50 additional sites across 15 countries committed to join the trial. TILVANCE-301 is intended to support accelerated and full U.S. approvals of Amtagvi in combination with pembrolizumab in frontline advanced melanoma, as well as full approval of Amtagvi in post-anti-PD-1 melanoma.

• Lifileucel in Non-Small Cell Lung Cancer (NSCLC)

  • Enrollment is accelerating in the IOV-LUN-202 registrational Phase 2 trial in post-anti-PD-1 NSCLC with high demand at clinical sites in the U.S., Canada, and Europe. Iovance is also activating sites in additional regions with strong track records for enrollment in NSCLC studies. Iovance expects to present updated data from the IOV-LUN-202 trial at a medical conference in 2025.

    • The FDA previously provided positive regulatory feedback on the proposed potency matrix for lifileucel in NSCLC, as well as the single-arm IOV-LUN-202 trial design to support accelerated approval of lifileucel in post-anti-PD-1 NSCLC.

    • Iovance expects data from the IOV-LUN-202 trial to support a potential accelerated U.S. approval for lifileucel in NSCLC in 2027.

  • Updated preliminary results from Cohort 3A in the IOV-COM-202 trial continue to demonstrate robust response rates and durability for lifileucel in combination with pembrolizumab in NSCLC patients who were not previously treated with immune checkpoint inhibitor therapy.

    • A confirmed objective response was observed in 9 of 14 EGFR wild type patients (64.3%), including 6 of 11 (54.5%) patients who also had difficult-to-treat PD-L1 negative disease.

    • Median duration of response (DOR) was not reached at a median study follow up of 26.5 months.

    • This data supports the opening of a new cohort, 3D, in the IOV-COM-202 trial to investigate lifileucel plus pembrolizumab following chemotherapy as part of frontline therapy for patients with EGFR wild type NSCLC, representing the majority of patients with an unmet medical need in this setting.

    • Additional Cohort 3A results are available in a late-breaking poster that will be presented at the upcoming Society for Immunotherapy of Cancer Annual Meeting (SITC) on November 9, 2024
      

• Lifileucel in Endometrial Cancer
  

  • Patient enrollment commenced in the IOV-END-201 Phase 2 trial to investigate lifileucel for advanced endometrial cancer patients who have progressed after platinum-based chemotherapy and anti-PD-1 therapy regardless of mismatch repair (MMR) status. IOV-END-201 is supported by preclinical and manufacturing success data presented at the International Gynecologic Cancer Society (IGCS) 2024 annual global meeting in October 2024, as well as positive feedback from gynecological oncology experts.

  • Endometrial cancer represents a significant opportunity for TIL cell therapy to address an additional unmet medical need in the post-anti-PD-1 treatment setting and may address both mismatch repair deficient and proficient tumors. There are no currently approved therapies in the second-line setting after frontline post-anti-PD-1 therapy and chemotherapy.
    
    

• Next Generation TIL Pipeline
  

  • IOV-4001 (PD-1 Inactivated TIL Cell Therapy): The first in human IOV-GM1-201 trial to investigate PD-1 inactivated TIL cell therapy (IOV-4001) in previously treated advanced melanoma and NSCLC is in the multi-center Phase 2 efficacy stage. Iovance continues to utilize the TALEN® technology licensed from Cellectis to develop other investigational gene-edited TIL cell therapies with multiple knockout targets to potentially improve efficacy.

  • Next Generation IL-2 for TIL Treatment Regimen: An Investigational New Drug application (IND) was submitted and allowed to proceed for a Phase 1/2 clinical trial of IOV-3001, a second-generation, modified interleukin-2 (IL-2) analog, for use in the TIL therapy treatment regimen. Non-human primate and IND-enabling studies of IOV-3001 demonstrated the potential for improved safety with strong effector T cell expansion.

  • Next Generation, Cytokine-Tethered TIL Therapy: IND-enabling studies are proceeding for IOV-5001, a genetically engineered, inducible, and tethered interleukin-12 (IL-12) TIL cell therapy. A clinical trial of a prior generation IL-12 TIL therapy at the National Cancer Institute showed improved efficacy with low cell doses and provides the rationale for modifying IOV-5001 to enhance TIL efficacy while optimizing safety. In preclinical studies, IOV-5001 drove superior antitumor activity in a simulated tumor microenvironment. These results will be featured in a poster at SITC on November 9, 2024. Iovance plans to submit a pre-IND meeting request to FDA in 2024 and commence clinical development for multiple indications in 2025.

Manufacturing Capacity Expansion

• The Iovance Cell Therapy Center (iCTC), and an FDA-approved contract manufacturer, currently have capacity to treat several thousands of patients annually. Expansion is currently underway for the iCTC campus to supply TIL cell therapies to more than 5,000 patients annually in the next few years. Iovance is also developing a manufacturing network to address more than 10,000 patients annually.

Third Quarter and Year to Date 2024 Financial Results

As of September 30, 2024, Iovance’s cash position is approximately $403.8 million, which includes net proceeds of approximately $200.0 million raised from an at-the market (ATM) equity financing facility during the second and early third quarter of 2024. The current cash position and anticipated product revenue are expected to be sufficient to fund current and planned operations into early 2026.

Net loss for the third quarter of 2024 was $83.5 million, or $0.28 per share, compared to a net loss of $113.8 million, or $0.46 per share, for the third quarter ended September 30, 2023. Net loss for the first nine months of 2024 was $293.6 million, or $1.03 per share, compared to a net loss of $327.7 million, or $1.44 per share, for the nine-month period ended September 30, 2023.

Revenue was $58.6 million for the third quarter of 2024 and consisted of product revenue from Amtagvi sales as well as recurring revenue from Proleukin. Iovance recognized $42.1 million in revenue from Amtagvi infusions that were completed during the third quarter of 2024 and $16.5 million in global revenue for Proleukin.

Revenue for the first nine months of 2024 was $90.4 million and reflected product revenue from Proleukin and Amtagvi. Revenue for the first nine months of 2023 was $0.7 million for global sales of Proleukin, which Iovance began to recognize during the three-month period ended June 30, 2023.

The increases in revenue in the third quarter and first nine months of 2024 over the prior year periods were primarily attributable to the U.S. launch of Amtagvi, including revenue recognized for Amtagvi, as well as significant growth in U.S. Proleukin revenue for use in the Amtagvi treatment regimen, beginning in the second quarter of 2024.

Cost of sales includes inventory, overhead and related cash and non-cash expenses that are directly associated with sales of Amtagvi and Proleukin, as well as manufacturing costs for Amtagvi. Cost of sales for the three months ended September 30, 2024 was $39.8 million, primarily attributed to $8.3 million in period costs associated with patient drop off and manufacturing success rates, $5.5 million for non-cash amortization expense for intangible assets, and $3.9 million in royalties payable on product sales. Cost of sales for the three months ended September 30, 2023 was $4.3 million, primarily related to non-cash amortization for intangible assets.

Cost of sales for the nine months ended September 30, 2024 was $78.5 million, primarily related to $17.2 million in certain costs associated with patient drop off and manufacturing success rates, $15.5 million in non-cash amortization expense for intangible assets, and $8.2 million royalties payable on product sales. Cost of sales for the nine months ended September 30, 2023 was $6.4 million, primarily related to non-cash amortization for intangible assets.

The increases in cost of sales in the third quarter and year to date 2024 over the prior year periods were primarily attributable to the initiation of product sales, commercial manufacturing and related cash and non-cash expenses tied to the U.S. launch of Amtagvi that began during the first quarter of 2024.

Research and development expenses were $68.2 million for the third quarter of 2024, a decrease of $19.3 million compared to $87.5 million for the same period ended September 30, 2023. Research and development expenses were $210.1 million for the first nine months of 2024, a decrease of $46.5 million compared to $256.6 million for the same period ended September 30, 2023.

The decreases in research and development expenses in the third quarter and year to date 2024 over the prior year periods were primarily attributable to the transition of Amtagvi to commercial manufacturing, decreased costs associated with certain clinical activities, and the completion of pre-commercial qualification activities in 2023. These decreases in research and development were partially offset by increases in headcount and related costs, including stock-based compensation resulting from growth in headcount.

Selling, general and administrative expenses were $39.6 million for the third quarter of 2024, an increase of $12.6 million compared to $27.0 million for the same period ended September 30, 2023. Selling, general and administrative expenses were $110.5 million for the first nine months of 2024, an increase of $33.5 million compared to $77.0 million for the prior year’s nine-month period.

The increase in selling, general and administrative expenses in the third quarter and year to date 2024 compared to the prior year periods was primarily attributable to increases in headcount and related costs, including stock-based compensation, to support the growth in the overall business and related corporate infrastructure, as well as legal costs and costs incurred to support the commercialization of Amtagvi and Proleukin.
