- 41 percent objective response rate (ORR) as assessed by the investigator in 42 patients who were primary refractory to anti-PD-1/L1 therapy -
- Median duration of response (DOR) was not reached as assessed by investigator at 12 months of study follow-up for the primary refractory subgroup -
Highlights from the poster, presented by study investigator
- In 42 primary refractory patients enrolled in Cohort 2 of C-144-01 study, defined as having had the best response of progressive disease (PD) on their first anti-PD-1/L1 treatment, an objective response rate (ORR) of 41 percent, as assessed by the investigator, was observed
- Median duration of response (DOR) was not reached at 12 months of study follow-up (range: 2.8+ to 21.2+ months)
- 71 percent of responders who are primary refractory to anti PD-1/L1 therapy remain on study
“Patients who are primary refractory to prior anti-PD-1/L1 therapy have very limited therapeutic options and yet form a large population of diagnosed metastatic melanoma patients,” commented
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. Primary refractory patients included 42 of the 66 dosed patients in Cohort 2 who had a best response of progressive disease to the first anti-PD-1/L1.
SMR 2019 is a global congress that unites melanoma clinicians and researchers to focus on multidisciplinary management of melanoma/skin cancer. This is the leading meeting for cutting edge data in melanoma.
About Iovance Biotherapeutics, Inc.
Iovance Biotherapeutics intends 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 is currently conducting pivotal studies in patients with metastatic melanoma and advanced cervical cancer. In addition, the company’s TIL therapies are being investigated for the treatment of patients with locally advanced, recurrent or metastatic cancers including head and neck and non-small cell lung cancer. Clinical studies of T cell therapy for blood cancers called peripheral blood lymphocyte (PBL) therapy are being planned. For more information, please visit www.iovance.com.
