Iovance Presents Updated Clinical Data for Tumor Infiltrating Lymphocyte (TIL) Therapy Lifileucel in Advanced Melanoma at ASCO Scientific Program

Median Duration of Response Not Reached at 18.7 Months of Median Study Follow Up

36.4% Overall Response Rate (ORR) Maintained

SAN CARLOS, Calif., May 29, 2020 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies, today presented long-term interim data from Cohort 2 in the C-144-01 study of lifileucel in advanced melanoma during an oral session at the American Society of Clinical Oncology’s (ASCO) ASCO20 Virtual Scientific Program.

“We are very pleased to present the long term follow up data for lifileucel in melanoma at the ASCO Scientific Program,” said Maria Fardis, Ph.D., President and Chief Executive Officer of Iovance Biotherapeutics. “The median duration of response has not been reached at 18.7 months of study follow up supporting potential benefit of the one-time treatment of lifileucel TIL therapy in advanced melanoma patients. The latest data at ASCO also demonstrate durable responses with lifileucel across the broad spectrum of our study population, including a wide age range of metastatic melanoma patients who have received prior anti-CTLA-4 and BRAF targeted treatments, and equally in patients with PD-L1 high and low status.”

Jason Chesney, MD PhD, Director, James Graham Brown Cancer Center, University of Louisville and C-144-01 study investigator stated, “One of the greatest challenges oncologists face today is the treatment of melanoma patients who have progressed on immune checkpoint and BRAF/MEK inhibitors.  The preliminary results of the C-144-01 study demonstrate that autologous tumor infiltrating lymphocytes (TILs; lifileucel) induce durable clinical responses in a significant percentage of this moribund population. Importantly, this new study opens the door for trials of TILs in many other cancer types and in combination with our growing repertoire of immunomodulatory agents.”

Updated interim results from Cohort 2 are now available from an oral abstract session titled, “Long-term follow up of lifileucel (LN-144) cryopreserved autologous tumor infiltrating lymphocyte therapy in patients with advanced melanoma progressed on multiple prior therapies.” As of the April 23, 2020 data extract for the oral presentation, lifileucel shows a 36.4% overall response rate (2 complete responses and 22 partial responses) and a disease control rate of 80% (n=66). Median duration of response (DOR) was not reached at 18.7 months of median study follow up (2.2 to 26.9+ months).

The Cohort 2 patients had heavily pretreated metastatic melanoma with high baseline disease burden. They have progressed on multiple prior therapies (3.3 mean prior therapies), including anti-PD-1 and BRAF/MEK inhibitors. The adverse event profile was consistent with the underlying advanced disease, lymphodepletion and IL-2 regimens.

Michael Kaplan, President and CEO of the Melanoma Research Alliance, stated, “While the last decade has brought incredible progress in delivering new treatments for melanoma, we know that more than half of patients with advanced melanoma are still in need of additional options. It is particularly exciting to see a new treatment approach, like lifileucel, that can offer hope and real results for some for whom checkpoint immunotherapy alone has yet to prove successful. The Melanoma Research Alliance is excited that Iovance has taken a significant step forward in ensuring more treatment options for patients who once had very few.”

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. After infusion, TIL reach tumor tissue, where they attack tumor cells. The company has completed dosing in the pivotal study in patients with metastatic melanoma and is currently conducting a pivotal study in patients with advanced cervical cancer. In addition, the company’s TIL therapy is being investigated for the treatment of patients with locally advanced, recurrent or metastatic cancers including head and neck and non-small cell lung cancer. A clinical study to investigate Iovance T cell therapy for blood cancers called peripheral blood lymphocyte (PBL) therapy is open to enrollment. For more information, please visit www.iovance.com.
