Iovance Biotherapeutics Announces Clinical Data Updates for Lifileucel in Advanced Melanoma at Upcoming ASCO 2021 Annual Meeting
86% Overall Response Rate (ORR) for Lifileucel in Combination with Pembrolizumab in Immune Checkpoint Inhibitor (ICI) Naïve Advanced Melanoma Patients in IOV-COM-202 Clinical Study
At Median of 28-Month Study Follow up, Median Duration of Response (DOR) not reached in Cohort 2 in post-PD1 Advanced Melanoma in C-144-01 Study; Data Support Use of Lifileucel Following Earlier Detection of Progression on Anti-PD-1 Therapy
Additional Data Updates at ASCO 2021 Meeting
SAN CARLOS, Calif., May 19, 2021 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies, today announced additional clinical data for lifileucel alone and in combination with pembrolizumab in patients with advanced melanoma. The data are available in two ASCO abstracts, with additional updates to be provided at the upcoming , to be held June 4-8, 2021.
Maria Fardis, Ph.D., President and Chief Executive Officer of Iovance Biotherapeutics, stated, “We are very excited that our latest clinical datasets demonstrate the broad potential for lifileucel in advanced melanoma. For the first time we are reporting results for lifileucel as an earlier treatment for advanced melanoma in combination with pembrolizumab, demonstrating an overall response rate (ORR) of 86% in patients who are naïve to anti-PD-1 therapy. We are impressed with the results for this combination regimen, particularly since pembrolizumab alone demonstrated a 33% ORR in a comparable patient population. In addition, in a post-PD1 advanced melanoma patient population in Cohort 2 in the C-144-01 study, shorter duration of prior anti-PD-1 therapy maximizes Duration of Response (DOR) to lifileucel treatment.”
Lifileucel in Combination with Pembrolizumab in Advanced Melanoma (IOV-COM-202 Study)
Early data suggest the response rate of lifileucel plus pembrolizumab may be additive 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 up to 12 patients who are naïve to ICI, or anti-PD-1, therapy. Six of the initial seven patients had a confirmed objective response, representing an 86% ORR (1 Complete Response (CR) and 5 Partial Responses (PR), with one best response of stable disease (abstract data extraction: February 2021). The longest duration of response was 16.8 months.
The Treatment-Emergent Adverse Event (TEAE) profile was consistent with the underlying disease and known Adverse Event (AE) profiles of pembrolizumab, NMA-LD and IL-2. These encouraging data confirm the potential feasibility and activity of lifileucel in combination with pembrolizumab in early-line treatment of patients with advanced melanoma. Updated results for the initial seven patients will be available in the upcoming ASCO poster.
Lifileucel Following anti-PD-1 therapy in Advanced Melanoma (C-144-01 clinical study)
As previously reported, the long-term follow-up data for Cohort 2 in the C-144-01 clinical study continue to demonstrate durability and depth of lifileucel TIL therapy response. DOR was not reached at 28.1 months of median study follow up and ORR remained at 36.4 percent.
New data in the ASCO abstract suggest that DOR was positively associated with shorter cumulative duration of prior anti-PD-1 therapy. In responders, the median cumulative duration and median prior lines of anti-PD-1 therapy was 4.4 months (range: 1.4-22.5 months) and 1.5 lines (range: 1-4). These results support earlier use of lifileucel following anti-PD-1 therapy instead of retreatment with anti-PD-1 based - regimens.
All patients in Cohort 2 had high baseline disease burden and were heavily pretreated (3.3 mean prior therapies), including anti-PD1 and BRAF/MEK inhibitors if BRAFV600 mutation positive. The adverse event profile was consistent with the underlying advanced disease, lymphodepletion and IL-2 regimens, with no new adverse events emerging over time. Updated results for Cohort 2 with longer duration of follow up will be part of the oral presentation during ASCO 2021.

About Iovance Biotherapeutics, Inc.
Iovance Biotherapeutics 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.
