Iovance Biotherapeutics Reports Fourth Quarter and Full Year 2021 Financial Results and Corporate Updates

Expanding TIL Platform in Multiple Solid Tumors and Treatment Settings

SAN CARLOS, Calif., Feb. 24, 2022 (GLOBE NEWSWIRE) — Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies (tumor infiltrating lymphocyte, TIL, and peripheral-blood lymphocyte, PBL), today reported fourth quarter and full year 2021 financial results and corporate updates.

Frederick Vogt, Ph.D., J.D., Interim President and Chief Executive Officer of Iovance, stated, “Throughout 2021, we continued to build upon the strength of clinical data for Iovance TIL therapy in multiple solid tumor types and treatment settings. Highlights included long-term clinical data for one-time treatment with lifileucel in metastatic melanoma, the potential to increase response rates for TIL therapy in combination with pembrolizumab as an earlier treatment for melanoma, cervical and head and neck cancers, as well as an important proof-of-concept for Iovance TIL therapy in non-small cell lung cancer. We also advanced our genetically modified TIL pipeline and expect to initiate our first clinical study of a gene-edited TIL product candidate later this year. Our top priority remains our ongoing work to address feedback from the U.S. Food and Drug Administration (FDA) regarding the potency assays for lifileucel to support our planned biologics license application (BLA) submission in the first half of this year. We remain increasingly confident in the broad potential for TIL as the next class of paradigm-shifting therapy for cancer patients with significant unmet need.”

Full Year 2021 Highlights and Recent Corporate Updates

Regulatory

• Potency assays for lifileucel: Following FDA feedback regarding the potency assays for lifileucel, Iovance has continued ongoing work developing and validating its potency assays and has engaged in discussions with the FDA during the second half of 2021. The anticipated BLA submission for lifileucel continues to be planned for the first half of 2022. Resolution of the potency assay for lifileucel in melanoma is also a key step towards regulatory plans in other indications.
• U.S. FDA Fast Track Designation for lifileucel in combination with pembrolizumab in metastatic melanoma: The FDA granted fast track designation for lifileucel in combination with pembrolizumab for the treatment of immune checkpoint inhibitor (ICI) naïve (frontline) metastatic melanoma based on the unmet medical need and potential advantages for this combination over available care.

Clinical

• Iovance TIL therapy (lifileucel) in metastatic melanoma:
  • Lifileucel in late line (post-anti-PD-1) melanoma: Follow up data as assessed by investigators from Cohort 2 (n=66) in the C-144-01 study of lifileucel in advanced melanoma were presented at the American Society for Clinical Oncology (ASCO) 2021 Annual Meeting. The overall response rate (ORR) was 36.4% (4.5% complete response rate and 31.8% partial response rate) and median duration of response (DOR) was not reached at 33.1 months of median study follow up. Iovance expects to report clinical data from the pivotal melanoma Cohort 4 as assessed by an independent review committee (IRC) in 2022 in connection with its BLA submission.
  • Lifileucel in combination with pembrolizumab in early line (anti-PD-1 naïve) melanoma (Cohort 1A in the IOV-COM-202 study): Initial clinical data were presented at ASCO 2021 and updated results were presented at Society for Immunotherapy of Cancer (SITC) 2021. The updated ORR was 60% and the complete response rate was 30% at a median follow up of 11.5 months in Cohort 1A (n=10). Based on these results, Iovance intends to expand Cohort 1A and define a development strategy in early line melanoma in 2022.
• Iovance TIL therapy (LN-145) in non–small cell lung cancer (NSCLC):
  • LN-145 monotherapy in metastatic NSCLC (mNSCLC): Results from Cohort 3B in the IOV-COM-202 study were highlighted at SITC 2021. LN-145 showed a 21.4% ORR in the full analysis set (n=28) and 25% in the efficacy-evaluable set (n=24). One complete response and one partial response were ongoing at 20.7 months and 3.0 months, respectively, at a median study follow up of 9.8 months. These results demonstrated activity for TIL therapy in heavily pretreated mNSCLC patients who received one or more prior systemic therapies, including anti-PD-1 therapy, and support the ongoing development strategy for LN-145 in second line mNSCLC patients in the IOV-LUN-202 study.
  • LN-145 in second-line mNSCLC: Enrollment is ongoing at more than 30 active clinical sites in the U.S., Canada and Europe for the IOV-LUN-202 study of LN-145 in patients with mNSCLC following a single line of approved systemic therapy. Iovance is engaged in discussions with the FDA about IOV-LUN-202 and intends to incorporate FDA feedback into the study design to support registration.
• Lifileucel in cervical cancer: The C-145-04 study is investigating lifileucel for the treatment of metastatic cervical cancer patients following chemotherapy (Cohort 1), after chemotherapy and anti-PD-1/PD-L1 therapy (Cohort 2), and in combination with pembrolizumab in patients who have not had therapy for advanced disease (Cohort 3).
  • Lifileucel monotherapy in advanced cervical cancer: Iovance is engaged in regulatory discussions about a potential BLA for lifileucel in cervical cancer and intends to execute an updated registrational strategy based on FDA dialogue and feedback.
  • Lifileucel in combination with pembrolizumab in early line cervical cancer: Initial results from Cohort 3 (n=14) in the C-145-04 study were presented at SITC 2021 and demonstrated an ORR of 57.1% at a median follow up of 7.6 months.
• Iovance TIL therapy combinations in additional solid tumor cancers: In Cohort 2A of the IOV-COM-202 study, Iovance is also investigating TIL therapy in combination with pembrolizumab in patients with head and neck squamous cell carcinoma (HNSCC) who are naïve to therapy with ICIs. Updated Cohort 2A data were presented at SITC 2021 and demonstrated a 38.9% ORR (n=18) at a median study follow up of 7.8 months. The IOV-COM-202 study is also investigating TIL combinations in patients with NSCLC including TIL therapy plus pembrolizumab (Cohort 3A) and TIL plus ipilimumab/nivolumab (Cohort 3C).

Next-Generation Genetically Modified TIL Products and Research Programs

• Iovance expects to initiate its first clinical study of a genetically modified TIL product candidate in 2022. The lead program, designated IOV-4001, leverages the TALEN® technology licensed from Cellectis S.A. to inactivate PD-1 expression in the TIL product.
• Additional targets for genetic modification using the TALEN technology, including double knock-out programs, are in preclinical development.
• Approaches to increase TIL potency using CD39/69 double negative TILs and gene knock-in targets are also in preclinical development.
• Accepted abstracts at the upcoming Transplantation & Cellular Therapy Meetings of ASTCT™ and CIBMTR® Tandem Meetings, April 23-26, 2022, describe TIL products manufactured from cryopreserved tumor samples shipped from Australia and a potential approach to optimize TIL memory-like phenotype and increase functionality during the manufacturing process.
• Iovance continues to advance additional research and preclinical studies of next generation TIL therapies and related technologies, including a novel IL-2 analog (IOV-3001).

Manufacturing

• Iovance Cell Therapy Center (iCTC): Commissioning activities were completed and clinical manufacturing of TIL product commenced at the iCTC, Iovance’s 136,000 square foot cell therapy manufacturing facility, in the third quarter of 2021. Commercial manufacturing remains on track to commence with a potential BLA approval.
• Generation 3 (Gen 3) manufacturing: TIL product manufactured using a shorter 16-day third generation process (Gen 3) is being investigated in cohorts of metastatic melanoma patients in the IOV-COM-202 study as well as NSCLC patients in the IOV-LUN-202 study.

Corporate

• Cash position of $602.1 million at December 31, 2021 is expected to be sufficient into 2024.
• A strong organization of approximately 350 employees with an average of more than four years of cell therapy experience is in place to advance research, development, manufacturing, and commercial launch preparations.
• Iovance continues to expand its intellectual property portfolio and currently owns more than 35 granted or allowed U.S. and international patents for TIL compositions and methods of treatment and manufacturing in a broad range of cancers. Iovance’s Gen 2 patent rights are expected to provide exclusivity into 2038. Iovance’s portfolio also includes patent applications and granted patents directed towards Gen 3 manufacturing, selected TIL products, stable and transient genetic TIL modifications, tumor digest and fragment compositions and methods (including cryopreservation), and combinations of checkpoint inhibitors and TIL products.
