Action mechanism: oncolytic virus. Talimogene laherparepvec is an investigational oncolytic immunotherapy designed to selectively replicate in tumors (but not normal tissue) and to initiate an immune response to target cancer cells that have metastasized. Talimogene laherparepvec was designed to work in two important and complementary ways. First, it is injected directly into tumors where it replicates inside the tumor's cells causing the cell to rupture and die in a process called lysis. The rupture of the cancer cells can release tumor-derived antigens, along with GM-CSF, that can stimulate a system-wide immune response where white blood cells are able to seek out and target cancer that has spread throughout the body.monoclonal antibody/immune checkpoint inhibitor. Keytruda® (pembrolizumab - MK-3475) is an investigational, highly selective monoclonal anti-PD-1 antibody designed to restore the natural ability of the immune system to recognize and target cancer cells by selectively achieving dual ligand blockade (PD-L1 and PD-L2) of the PD-1 protein. By blocking PD-1, MK-3475 enables activation of the immune system’s T-cells that target cancer by essentially releasing a brake on the immune system. MK-3475 is currently being studied in three clinical trials for advanced melanoma including a Phase III trial of MK-3475 versus ipilimumab in ipilimumab-naïve advanced melanoma patients (PN 006). Enrollment is complete in the advanced melanoma cohorts in the company’s Phase IB trial (PN 001) and the Phase II trial (PN 002) comparing two doses of MK-3475 versus chemotherapy in patients with advanced melanoma who have progressed after prior therapy. Pembrolizumab is being evaluated across more than 30 types of cancers, as monotherapy and in combination. It is anticipated that by the end of 2014, the pembrolizumab development program will grow to more than 24 clinical trials, enrolling an estimated 6,000 patients at nearly 300 clinical trial sites worldwide. In April 2013, MK-3475 has received a Breakthrough Therapy designation for advanced melanoma from the FDA. Keytruda® is the first approved drug that blocks the PD-1 cellular pathway.
Disease: recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN).
Details: * On May 29, 2015, Amgen and Merck&Co announced an expanded collaboration to evaluate the efficacy and safety of talimogene laherparepvec, Amgen's investigational oncolytic immunotherapy, in combination with Keytruda® (pembrolizumab), Merck's anti-PD-1 therapy, in a Phase 1, open-label trial of patients with recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN). In addition, the companies announced that a global, randomized Phase 3 trial evaluating the combination in patients with regionally or distantly metastatic melanoma is being initiated. As previously announced, the compounds are being studied in a Phase 1, open-label trial in this patient population.
