Recent and Third Quarter 2023 Highlights and Corporate Updates

Lifileucel in Advanced Melanoma
Regulatory Highlights

• The BLA Priority Review remains on track for lifileucel for patients with advanced melanoma with a PDUFA date of February 24, 2024. Iovance continues to work with the FDA to expedite approval of lifileucel in advance of the PDUFA date. All pre-approval inspections of clinical sites, internal and external manufacturing, and testing facilities have been successfully completed.
• Following lifileucel’s initial U.S. launch, Iovance’s expansion strategy is expected to more than double the total addressable advanced melanoma patient population for lifileucel. Iovance has recently made significant progress toward the goal of bringing lifileucel to new geographies:
  • Following recent positive feedback from the European Medicines Agency (EMA) on Cohorts 2 and 4 of the C-144-01 clinical trial, Iovance plans to submit a marketing authorization application (MAA) in the European Union for lifileucel in advanced melanoma in the first half of 2024.
  • Iovance is also engaged with the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom (U.K.) and Health Canada. Iovance also plans to submit an MAA for lifileucel in the U.K. and a new drug submission (NDS) in Canada in the second half of 2024.
  • Additional regulatory submissions for lifileucel are planned for Australia and other countries with significant populations of advanced melanoma patients.
• Patient enrollment and global site activation continue in the registrational Phase 3 TILVANCE-301 trial to support accelerated and full approvals of lifileucel in combination with pembrolizumab in frontline advanced melanoma. Recent site activations include additional U.S. sites and the first site in Australia, with regulatory clearances obtained to open sites in the U.K. and Canada. TILVANCE-301 is a confirmatory trial to support full approval of lifileucel in post-anti-PD-1 advanced melanoma. TILVANCE-301 remains on track to be well underway at the time of potential accelerated approval for lifileucel in this initial indication.
• A subanalysis from the C-144-01 trial of patients with advanced mucosal melanoma was presented at the European Society for Medical Oncology (ESMO) Congress 2023, October 20-24, 2023, Madrid, Spain. In these difficult-to-treat patients, a confirmed objective response rate (ORR) of 50.0% was observed, with 67% of responses ongoing at 24+ months.
  
  

Manufacturing and Commercial Preparations

• Pre-approval onboarding steps to treat melanoma patients with lifileucel upon approval have been completed at approximately 30 ATCs. Approximately 50 ATCs are expected to be onboard within 90 days of the PDUFA date, demonstrating the strong excitement and demand in the melanoma community for the launch of lifileucel. The Iovance team is partnering with ATCs to build their TIL service lines and working with payers to speed reimbursement. Iovance expects rapid uptake of lifileucel in the U.S. market in 2024 given the extensive commercialization, manufacturing, patient access, and reimbursement preparations, as well as the lack of alternative options for advanced melanoma patients. Following the ongoing successful integration of the Proleukin^® acquisition, significant revenue increases from the Proleukin^® business are also expected in 2024.
• To date, more than 600 patients have been treated with Iovance TIL therapy manufactured using proprietary Iovance processes, with a manufacturing success rate of more than 90%.
• The Iovance Cell Therapy Center (iCTC) is currently manufacturing TIL therapies for clinical trials while executing activities to support BLA review in preparation for initiating commercial supply. The iCTC facility currently has annual capacity to supply TIL therapies for 2,000+ patients, with buildable shell space to ultimately supply TIL therapies for 5,000+ patients. Iovance also has additional contract manufacturing flexibility and capacity to meet potential commercial and clinical demand.
  
  

Iovance TIL Therapy in Advanced Non-Small Cell Lung Cancer (NSCLC)

• Registrational Phase 2 Trial IOV-LUN-202 in Post-Anti-PD-1 NSCLC: Enrollment in IOV-LUN-202 is ongoing at more than 40 clinical sites in the U.S., Canada, and Europe, and is on track to be completed in the second half of 2024. There is strong physician interest and momentum for center participation following the positive preliminary data analysis and FDA regulatory feedback that the design of the single-arm IOV-LUN-202 trial may be acceptable for approval of LN-145 TIL therapy in post-anti-PD-1 NSCLC.
• NSCLC Clinical Trial Regulatory Update: Iovance is planning to meet with the FDA in early 2024 to discuss a potential registrational trial of lifileucel in combination with pembrolizumab after standard of care chemotherapy to serve as the confirmatory trial for IOV-LUN-202 in post-anti-PD-1 melanoma and to support accelerated approval in frontline advanced NSCLC.
• Iovance TIL Therapy in Combination with Anti-PD-1 in Frontline Advanced NSCLC: Detailed results from Cohort 3A of the IOV-COM-202 clinical trial, exploring TIL in combination with pembrolizumab in anti-PD-1 naïve advanced NSCLC patients, were presented at an oral session during the IASLC 2023 World Congress on Lung Cancer (WCLC 2023).  
  
  

Iovance TIL Therapy in Endometrial Cancer

• Iovance is expanding its robust clinical portfolio with a new TIL therapy program in post-anti-PD-1 and post-chemotherapy advanced endometrial cancer. Advanced endometrial cancer represents a significant opportunity for TIL therapy, with no currently approved therapies in the emerging second-line setting, post-anti-PD1 therapy and chemotherapy. A Phase 1/2 study in mismatch repair (MMR) deficient and MMR proficient patient populations is expected to commence in the first half of 2024. More than 10,000 women are expected to die in the U.S. in 2023 from endometrial cancer, representing a significant patient population with unmet medical need.¹
  
  

Additional Pipeline Highlights

• Additional clinical trials of Iovance TIL therapies include IOV-GM1-201 to investigate PD-1 inactivated TIL therapy (IOV-4001) in previously treated advanced melanoma or NSCLC as well as pivotal Cohort 2 in the ongoing C-145-04 trial of lifileucel to support a BLA in cervical cancer following progression on or after chemotherapy and pembrolizumab.
• A novel interleukin-2 (IL-2) analog (IOV-3001) is in Investigational New Drug (IND)-enabling studies supporting its use as part of the TIL treatment regimen following TIL infusion.
• Additional research and preclinical studies are exploring approaches to increase TIL potency using CD39/69 double negative TILs and stable gene incorporation enhancements such as tethered cytokines.
  
  

Corporate Updates

• As of September 30, 2023, Iovance’s unaudited cash position is approximately $427.8 million. Following strategic portfolio prioritization, as well as completion of many one-time commercial and manufacturing readiness activities, quarterly and annual operating expenses are expected to be reduced in the remainder of 2023 and 2024, while continuing all key clinical programs and utilizing internal manufacturing capabilities.
• Iovance currently owns more than 60 granted or allowed U.S. and international patents for TIL compositions and methods of treatment and manufacturing in a broad range of cancers, with Gen 2 patent rights expected to provide exclusivity into 2038. More information on Iovance’s patent portfolio is available on the Intellectual Property page on www.iovance.com.

Third Quarter and Year-to-Date Financial Results

Iovance had $427.8 million in cash, cash equivalents, investments and restricted cash at September 30, 2023, compared to $478.3 million at December 31, 2022. The combined net proceeds in the third quarter of 2023 from the Company’s public offering in July 2023 and the at-the market (ATM) equity financing facility were approximately $203.2 million. The current cash position and anticipated revenue in 2024 from lifileucel and Proleukin^® is expected to be sufficient to fund current and planned operations into 2025.

Net loss for the third quarter ended September 30, 2023, was $113.8 million, or $0.46 per share, compared to a net loss of $99.6 million, or $0.63 per share, for the third quarter ended September 30, 2022. Net loss for the nine months ended September 30, 2023, was $327.7 million, or $1.44 per share, compared to a net loss of $290.6 million, or $1.85 per share, for the same period ended September 30, 2022.

Revenue for the third quarter and nine months ended September 30, 2023, was $0.5 million and $0.7 million, respectively, and comprised of product sales following the Proleukin^® acquisition in May 2023. There was no revenue for the third quarter and nine months ended September 30, 2022. Cost of sales for the third quarter and nine months ended September 30, 2023, was $4.3 million and $6.4 million, respectively, and comprised of cost of inventory associated with sales of Proleukin^® as well as $4.0 million and $5.9 million, respectively, of non-cash amortization expenses of the acquired intangible asset for developed technology. There was no cost of revenues for the third quarter and nine months ended September 30, 2022.

Research and development expenses were $87.5 million for the third quarter ended September 30, 2023, an increase of $15.0 million compared to $72.5 million for the same period ended September 30, 2022. Research and development expenses were $256.6 million for the nine months ended September 30, 2023, an increase of $42.4 million compared to $214.2 million for the same period ended September 30, 2022.

The increases in research and development expenses in the third quarter and the nine months ended September 30, 2023, over the prior year periods were primarily attributable to growth of the internal research and development team, as well as higher costs related to facilities and the initiation of new clinical trials, including the Phase 3 TILVANCE trial, which were partially offset by a decrease in stock-based compensation expense.

Selling, general and administrative expenses were $27.0 million for the third quarter ended September 30, 2023, a decrease of $0.9 million compared to $27.9 million for the same period ended September 30, 2022. Selling, general and administrative expenses were $77.0 million for the nine months ended September 30, 2023, a decrease of $0.6 million compared to $77.6 million for the same period ended September 30, 2022.

The decrease in selling, general and administrative expenses in the third quarter and the nine months ended September 30, 2023, compared to prior year periods was primarily attributable to the decrease in stock-based compensation expense and other costs related to the timing of spend compared to the prior year period, including marketing, advertising, and legal costs, partially offset by costs associated with the growth in the overall business. For additional information, please see the Company’s Selected Condensed Consolidated Balance Sheet and Statement of Operations below.
