Highlights from the poster presentation include:
An objective response rate (ORR) of 35 percent as assessed by IRC as compared to 36 percent as assessed by investigator
Median DOR was not reached as assessed by either IRC (range: 1.6+ to 21.2+ months) or investigator (range: 2.2 to 21.2+ months) at 11.3 months median follow up. In addition, based on the most recent data cut from the study, median DOR was not reached as assessed by investigator at 12.8 months of median study follow-up.
An overall concordance rate of 89.4 percent between investigator assessment and IRC assessment (n=66)
"We are pleased to see continued evidence of durability with lifileucel therapy as patients are evaluated with longer term follow-up," commented Maria Fardis, Ph.D., MBA, president and chief executive officer of Iovance Biotherapeutics. "In addition, concordance between IRC assessment and investigator reported results is highly favorable in this metastatic disease setting as compared with the published literature. These results continue to show that lifileucel offers a potential therapeutic option for the metastatic melanoma patients enrolled in this study. We continue to enroll patients in the pivotal cohort of the study, Cohort 4, which is expected to serve as the basis for an expected Biologics License Application (BLA) submission for lifileucel in late 2020."
Cohort 2 in the ongoing C-144-01 study includes consecutively dosed post-PD-1 patients with Stage IIIC/IV unresectable melanoma who also have received BRAF/MEK therapy if clinically indicated. In this study, patients had experienced a mean of 3.3 lines of prior therapy including anti-PD1 blocking antibody, and the patients had a high baseline tumor burden. The adverse event profile of lifileucel treatment in the C-144-01 study continued to be consistent with the underlying advanced disease and the profile of the lymphodepletion and IL-2 regimens.
