Median Duration of Response (DOR) Not Reached at 33.1 Months of Median Study Follow Up in Cohort 2 in C-144-01 Study
Early Intervention with Lifileucel Following Progression on Anti-PD-1 Therapy May Maximize Benefit
ASCO Update Conference Call and Webcast at 12 p.m. ET Today
SAN CARLOS, Calif., June 06, 2021 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies, today announced updated clinical data for lifileucel from Cohort 2 in the C-144-01 clinical study in patients with advanced melanoma. The data were presented in an oral presentation at the ASCO 2021 Annual Meeting.
Omid Hamid, M.D., Chief of Research/Immuno-Oncology, The Angeles Clinic & Research Institute, stated, “Anti-PD-1 therapy is a mainstay class of treatment offering several therapeutic options for metastatic melanoma. For patients who progress on anti-PD-1 therapy, there is an unfulfilled need for efficacious and durable treatment options. The latest results with lifileucel suggest that early intervention with lifileucel TIL therapy, immediately upon progression on anti-PD-1 therapy, may offer better outcomes and longer duration of response. These data offer evidence that patients have had positive treatment experiences with lifileucel, and I believe TIL therapy has the potential to become an important option within the melanoma treatment landscape.”
Friedrich Graf Finckenstein, M.D., Chief Medical Officer of Iovance, stated, “Our latest data for Cohort 2 in the C-144-01 clinical study are very exciting and continue to support the durability of responses after lifileucel in challenging to treat patients with melanoma. Median DOR has still not been reached at 33 months of median study follow up. We are also reporting the important observation that a shorter duration of prior anti-PD-1 therapy is associated with longer duration of response after lifileucel. We are committed to bringing lifileucel to patients as soon as we can.”
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. Median DOR was not reached at 33.1 months of median study follow up (range: 2.2 to 38.5+ months) and Overall Response Rate, or ORR, remained at 36.4% (data extraction: April 2021). Responses deepened over time and one patient converted from partial to complete response at 24 months post lifileucel infusion.
A multivariable model showed that for every six-month decrease in cumulative duration of prior anti-PD-1 therapy, DOR to lifileucel will be nearly doubled. These results suggest that early intervention with lifileucel at the time of initial progression on anti-PD-1 therapy may maximize benefit.
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 safety risks identified for lifileucel during long-term follow-up.

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.
