LOS ANGELES, July 30, 2014 (GLOBE NEWSWIRE) -- Lion Biotechnologies, Inc. (OTCQB:LBIO), a biotechnology company that is developing novel cancer immunotherapies based on tumor infiltrating lymphocytes (TILs), today announced that it has entered into a clinical trial grant agreement with Moffitt Cancer Center to expand an ongoing Phase 1 study of TILs combined with ipilimumab in patients with metastatic melanoma.
Under the agreement, Lion will give Moffitt funding to enroll an additional ten qualified patients into the clinical trial, bringing the total number of subjects to 20. The primary objective of the trial is to evaluate the safety and preliminary efficacy of administering ipilimumab in combination with TILs as a first-line therapy for patients with metastatic melanoma. Secondary outcome measures include overall response rate, or tumor shrinkage, and progression-free survival.
Marketed by Bristol-Myers Squibb as Yervoy®, ipilimumab is an immune checkpoint inhibitor that the FDA approved for the treatment of metastatic melanoma in 2011. TIL therapy, an experimental melanoma treatment that was developed at the National Cancer Institute, is a type of adoptive cell therapy that is made by extracting T-cells from patients' own tumors, expanding them by thousands in a laboratory, and injecting them back into the patient. In the expanded trial, the co-stimulatory antibody CD137 will be used to accelerate the growth of these T-cells.
"Despite major treatment advances in recent years, metastatic melanoma is still a deadly disease for which new therapeutic approaches are urgently needed," commented Amod Sarnaik, MD, the trial's principal investigator and a leading expert in adoptive cell transfer. "Clinical evidence suggests that combining TILs with checkpoint inhibitors, such as ipilimumab, may provide greater benefit to a larger number of patients than either therapy alone. We look forward to further investigating the synergies of this promising treatment combination in the expanded trial, which we are actively enrolling."
