86% Overall Response Rate (ORR) and 43% Complete Response Rate in Immune Checkpoint Inhibitor (ICI) Naïve Advanced Melanoma Patients in IOV-COM-202 Clinical Study
Initial 7 Patients Show 3 Complete Responses, 3 Partial Responses and 1 Best Response of Stable Disease
ASCO Update Conference Call and Webcast on Sunday, June 6 at 12 p.m. ET
SAN CARLOS, Calif., June 04, 2021 (GLOBE NEWSWIRE) — Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies, today announced clinical data for lifileucel in combination with pembrolizumab in patients with advanced melanoma. The data are now available in an ePoster at the ASCO 2021 Annual Meeting.
Antonio Jimeno M.D., Ph.D., Professor of Medicine/Oncology and Otolaryngology at the University of Colorado School of Medicine stated, “Anti-PD-1 therapy has become standard of care in frontline melanoma, yet we are still looking for ways to help more patients respond and to improve upon the depth and durability of responses. The 86% Overall Response Rate (ORR) for lifileucel in combination with pembrolizumab is remarkable and suggests a potential additive effect for early-line treatment of patients with melanoma. I look forward to investigating this treatment approach in additional patients with melanoma as well as in other tumor types such as head and neck squamous cancer.”
Friedrich Graf Finckenstein, M.D., Chief Medical Officer of Iovance, stated, “We are very pleased with the initial efficacy and safety results for lifileucel in combination with pembrolizumab in patients who are naïve to anti-PD-1 therapy. We are particularly impressed by the complete response observations and noted conversion of several partial to complete responses over time. These data in melanoma also build upon our initial data for TIL in combination with pembrolizumab in head and neck cancer, supporting the broader potential for TIL in earlier anti-PD-1 naïve treatment settings across indications.”
Early data suggest the response rate of lifileucel plus pembrolizumab may be additive and confirm the potential feasibility and activity of this combination in patients with immune checkpoint inhibitor (ICI)-naïve advanced melanoma. Cohort 1A in the IOV-COM-202 study is evaluating lifileucel in combination with pembrolizumab in patients who are naïve to ICI, or anti-PD-1, therapy. Initial patients (n=7) enrolled in Cohort 1A had high tumor burden at baseline, and 71.4% had not received any prior systemic therapy.
Six of the seven patients had a confirmed objective response, representing an 86% ORR (2 complete responses (CR), 1 unconfirmed CR (uCR) who had not yet reached the confirmatory CR assessment, and 3 partial responses (PR)), with one best response of stable disease. Responses deepened over time and the CR/uCR rate was 43%. Poster data extraction was in April 2021 and the median follow up was 8.2 months. ORR was investigator-assessed per RECIST 1.1. In a subsequent data cut in May 2021, all ongoing responses continued.
The Cohort 1A results also demonstrated that lifileucel can be safely combined with pembrolizumab. The treatment-emergent adverse event (TEAE) profile was consistent with the underlying disease and known adverse event (AE) profiles of pembrolizumab, non-myeloablative lymphodepletion (NMA-LD) and IL-2. The median number of doses of IL-2 and pembrolizumab were six and 10, respectively.

About Iovance Biotherapeutics, Inc.
Iovance aims to improve patient care by making T cell-based immunotherapies broadly accessible for the treatment of patients with solid tumors and blood cancers. Tumor infiltrating lymphocyte (TIL) therapy uses a patient’s own immune cells to attack cancer. TIL cells are extracted from a patient’s own tumor tissue, expanded through a proprietary process, and infused back into the patient. Upon infusion, TIL reach tumor tissue, where they attack cancer cells. The company has completed dosing in pivotal programs in patients with metastatic melanoma and cervical cancer. In addition, the company’s TIL therapy is being investigated in a registration-supporting study for the treatment of patients with locally advanced, recurrent or metastatic non-small cell lung cancer (NSCLC). Clinical studies are also underway to evaluate TIL in earlier stage cancers in combination with currently approved treatments, and to investigate Iovance peripheral blood lymphocyte (PBL) T cell therapy for blood cancers.
