Post-Anti-PD-1 Non-Small Cell Lung Cancer TIL Program Advances into Registrational Development 

SAN CARLOS, Calif., Aug. 08, 2023 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a biotechnology company focused on innovating, developing and delivering novel polyclonal tumor infiltrating lymphocyte (TIL) therapies for patients with cancer, today reported second quarter and first half 2023 financial results and corporate updates.

Frederick Vogt, Ph.D., J.D., Interim President and Chief Executive Officer of Iovance, stated, “Iovance is making significant progress in executing on our goals. The Priority Review of our BLA for lifileucel in advanced melanoma remains on track and continues to progress well as we work collaboratively with FDA and approach a potential approval and launch this year. We acquired Proleukin^®, which will provide revenue, streamline our supply chain and logistics, reduce our future cost of goods and lower expenses for IL-2 used with TIL therapies. We are also excited about our NSCLC pipeline, with a registrational trial and positive preliminary data in post-anti-PD-1 patients and the upcoming full data presentation for TIL therapy in combination with pembrolizumab in ICI naïve patients. We are well positioned to execute on our regulatory, pipeline, manufacturing and commercial launch activities to advance our mission to be the global leader in TIL therapy.”

Recent and Second Quarter 2023 Highlights and Corporate Updates

Iovance TIL Therapy (Lifileucel) in Advanced Melanoma
Regulatory Highlights

• The U.S. Food and Drug Administration (FDA) accepted the Biologics License Application (BLA) for lifileucel for patients with advanced melanoma. The FDA granted lifileucel Priority Review and assigned November 25, 2023, as the target action date for a decision under the Prescription Drug User Fee Act (PDUFA).
• The first patient was randomized in the registrational Phase 3 global TILVANCE-301 trial to support accelerated and full approvals of lifileucel in combination with pembrolizumab in frontline advanced melanoma. TILVANCE-301, which is also a confirmatory trial to support full approval of lifileucel in post-anti-PD-1 advanced melanoma, is expected to be well underway at the time of potential accelerated approval for lifileucel in this initial indication.

Manufacturing and Commercial Preparations

• 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, including pre-approval inspection readiness, 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 from this facility. Iovance has additional flexibility and capacity through contract manufacturers to meet potential commercial and clinical demand.
• Several initiatives are underway ahead of potential commercialization, including on-boarding and personnel training at Authorized Treatment Centers (ATCs), patient access, education and awareness, and other commercial launch readiness activities.

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

• Registrational Phase 2 Trial IOV-LUN-202 in Post-Anti-PD- 1 NSCLC:
  • At a Type B Pre-Phase 3 meeting, the FDA provided positive regulatory feedback that the design of the single-arm Phase 2 IOV-LUN-202 trial may be acceptable for approval of LN-145 TIL therapy in post-anti-PD-1 NSCLC. Based on the regulatory discussions, Iovance completed a preliminary analysis and plans to enroll a total of approximately 120 patients into the registrational IOV-LUN-202 trial.
  • In a preliminary analysis of IOV-LUN-202, ORR was 26.1% by RECIST v1.1 (n=6, one complete response and five partial responses). All responses remained ongoing at the data cut off and the median duration of response (DOR) was not reached (1.4+ to 9.7+ months).
  • Enrollment in IOV-LUN-202 is ongoing at more than 40 active clinical sites in the U.S., Canada and Europe, and is expected to complete in the second half of 2024. 
• 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 will be presented at an oral session during the IASLC 2023 World Congress on Lung Cancer (WCLC 2023). Cohort 3A explores the combination of TIL therapy (LN-145) and pembrolizumab in anti-PD-1 naïve advanced NSCLC patients.
  • Iovance plans a meeting with the FDA in 2023 to discuss Cohort 3A results and a potential registrational trial of lifileucel in combination with pembrolizumab after standard of care chemotherapy to support accelerated approval in frontline advanced NSCLC and to serve as the confirmatory trial for IOV-LUN-202.
    

Additional Clinical Pipeline Highlights

• Iovance PD-1 inactivated TIL therapy (IOV-4001) in previously treated advanced melanoma or mNSCLC: The ongoing IOV-GM1-201 trial of Iovance’s first genetically modified TIL therapy, IOV-4001, is among the first clinical trials of a genetically modified TIL cell therapy for solid tumors.
• Lifileucel in advanced cervical cancer: Additional patients continued to enroll in pivotal Cohort 2 in the ongoing C-145-04 trial to support a BLA in cervical cancer following progression on or after chemotherapy and pembrolizumab.

Research Programs for Next-Generation TIL Therapies and Related Technologies

• Additional programs using the gene editing TALEN^® technology are on track to enter clinical development in 2024, including genetically modified TIL therapy with multiple inactivated checkpoint targets.
• 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.
• A novel interleukin-2 (IL-2) analog (IOV-3001) is in IND-enabling studies supporting its use as part of the TIL treatment regimen following TIL infusion.
  

Corporate Updates

• Iovance completed the acquisition of worldwide rights to Proleukin^® (aldesleukin) from Clinigen Limited in May of 2023. Proleukin is an interleukin-2 (IL-2) product with uses that include administration following TIL infusion to promote T-cell activity. Iovance expects Proleukin to provide revenue, secure the IL-2 supply chain and logistics surrounding TIL therapy administration, and lower cost of goods and clinical trial expenses for Proleukin used with TIL therapies.
• As of June 30, 2023, Iovance’s cash position was approximately $317.3 million. In July of 2023, Iovance raised estimated net proceeds from a common stock public offering of approximately $161.4 million. Inclusive of the net proceeds from the offering, the current cash position is expected to fund Iovance’s operating plan into the end of 2024.
• 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.

Second Quarter and First Half 2023 Financial Results

Iovance had $317.3 million in cash, cash equivalents, investments and restricted cash at June 30, 2023, compared to $478.3 million at December 31, 2022. With the estimated net proceeds from the common stock public offering of approximately $161.4 million raised in July of 2023, the cash position is expected to be sufficient to fund current and planned operations into the end of 2024.

Net loss for the second quarter ended June 30, 2023, was $106.5 million, or $0.47 per share, compared to a net loss of $99.3 million, or $0.63 per share, for the second quarter ended June 30, 2022. Net loss for the six months ended June 30, 2023, was $213.9 million, or $0.98 per share, compared to a net loss of $191.0 million, or $1.21 per share, for the same period ended June 30, 2022.

Revenue for the six months ended June 30, 2023, was $0.2 million, comprised of product sales following the Proleukin acquisition in May of 2023. There was no revenue for six months ended June 30, 2022. Cost of sales for the six months ended June 30, 2023, was $2.1 million, including $1.9 million of non-cash amortization of the acquired intangible asset for developed technology during the second quarter. There was no cost of revenues for the six months ended June 30, 2022.

Research and development expenses were $86.3 million for the second quarter ended June 30, 2023, an increase of $12.9 million compared to $73.4 million for the same period ended June 30, 2022. Research and development expenses were $169.1 million for the six months ended June 30, 2023, an increase of $27.4 million compared to $141.7 million for the same period ended June 30, 2022.

The increases in research and development expenses in the second quarter and first half of 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, internal research programs and the Phase 3 TILVANCE trial, which were partially offset by a decrease in stock-based compensation expense.

Selling, general and administrative expenses were $21.9 million for the second quarter ended June 30, 2023, a decrease of $4.4 million compared to $26.3 million for the same period ended June 30, 2022. Selling, general and administrative expenses were $50.0 million for the six months ended June 30, 2023, an increase of $0.3 million compared to $49.7 million for the same period ended June 30, 2022.

The decrease in selling, general and administrative expenses in the second quarter of 2023 compared to prior year period was primarily attributable to the capitalization of expenses associated with the Proleukin acquisition upon the transaction close. Decreases in other costs are related to the timing of spend compared to the prior year period, including marketing, advertising, licensing and insurance costs, partially offset by costs associated with the growth in the overall business. The increase in selling, general and administrative expenses in the first half of 2023 compared to the prior year period was primarily attributable to growth of the internal general and administrative and commercial teams, offset by a decrease in legal fees and other costs.
