IOVA,
Somewhat puzzled by the two events happening right after each other. First the $500 mil raise and then releasing primary info on a trial.
Cohort 4 Early Data Shows 32.4% ORR by Investigator Assessment at 5.3 Months of Median Study Follow up
Cohort 2 Median Duration of Response Not Reached at 18.7 Months of Median Study Follow Up and 36.4% ORR
SAN CARLOS, Calif., May 27, 2020 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies, today announced initial data from pivotal Cohort 4 and updated long-term data from Cohort 2 in the C-144-01 study of lifileucel in advanced melanoma.
“We are very pleased to announce our pivotal Cohort 4 early data from the C-144-01 clinical study in advanced melanoma today,” said Maria Fardis, Ph.D., President and Chief Executive Officer of Iovance Biotherapeutics. “The data from the first 68 patients in Cohort 4, with a 32.4% overall response rate (ORR) at 5.3 months of median study follow up, is highly consistent with what we have observed in Cohort 2 with comparable study follow up. For Cohort 2, median duration of response has not been reached at 18.7 months of study follow up. Available care for metastatic melanoma patients enrolled into our program is chemotherapy, which has been reported to offer a 4-10% response rate with a very short median duration of response. Together, these early data continue to support the potential benefit of the one-time administration of lifileucel TIL therapy in advanced melanoma patients.”
Interim Pivotal Cohort 4 Results
Initial results from the pivotal Cohort 4 in the C-144-01 clinical study is available for 68 patients with two radiological assessments, as determined by investigator. Primary endpoint for the C-144-01 Cohort 4 study is ORR by independent review committee and secondary endpoint is ORR by investigator. Lifileucel shows a 32.4% overall response rate (1 complete response and 21 partial responses, 2 of which are yet to be confirmed with follow up visits) and a disease control rate of 72.1% as of the data cut off of 16 Mar 2020. This data is consistent with what was noted in Cohort 2 at 6 months of median study follow up. The ORR was 33% as reported in SITC 2018 abstract.
The Cohort 4 metastatic melanoma patients have a similar patient characteristic profile to Cohort 2 with high baseline disease burden. They have progressed on multiple prior therapies, including anti-PD-1 and BRAF/MEK inhibitors. The adverse event profile was consistent with Cohort 2 and with the underlying advanced disease, lymphodepletion and IL-2 regimens. Cohort 4 dosed a total of 89 patients, and additional updates on Cohort 4 will be presented at upcoming medical meetings. Iovance remains on track to submit a biologics licensing application (BLA) for lifileucel in late 2020.
Updated Cohort 2 Results
Updated results from Cohort 2 will be presented at the ASCO20 Virtual Scientific Program during 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.”
