Vaccinex, Inc. VCNX announced that it has achieved full enrollment in an early-stage study on its lead pipeline candidate pepinemab (VX15/2503). The study is evaluating pepinemab in combination with Merck KGaA/ Pfizer’s PFE anti-PD-L1 inhibitor Bavencio (avelumab) for the treatment of advanced non-small cell lung cancer (NSCLC).Primary completion of the study is expected by the end of this year while top-line results are expected in the first half of 2020. Vaccinex is conducting this study in collaboration with Merck KGaA and Pfizer.The phase Ib/II CLASSICAL-Lung study evaluated the safety and potential efficacy of the pepinemab + Bavencio combo in patients with advanced NSCLC, who are either immunotherapy naïve or have failed prior immunotherapy with an approved checkpoint inhibitor.Notably, pepinemab in combination with Bavencio showed promising anti-tumor activity in the given patient population.Moreover, interim data from the study showed that majority of patients benefited from the combo of pepinemab + Bavencio through either halting or reversing tumor progression. The outcomes were presented at the annual meeting of the American Society of Clinical Oncology held in June.Shares of Vaccinex have rallied 36.1% so far this year versus the industry’s decrease of 2.1%.We would like to remind investors that Vaccinex is leveraging its SEMA4D antibody platform to develop pepinemab.
