COLLABORATIONS

Apexigen and Yale Cancer Center to evaluate APX005M +Cabiralizumab + Nivolumab in PD-(L)1 progressors mNSCLC, metastatic melanoma and RCC patients

“There is an urgent need to find effective therapies for the growing number of patients who have not responded to checkpoint inhibitors,” said Xiaodong Yang, M.D., Ph.D., President and Chief Executive Officer of Apexigen. “CD40 has a fundamental role in the activation of both innate and adaptive immunity, and we believe that CD40 activation by APX005M will become a key component of a number of promising new I-O therapeutic regimens for treating cancer patients.”

https://platform.twitter.com/widgets.js
“This most exciting collaboration between Apexigen and Yale is a result of studies with tumor bearing mice that are poorly responsive to inhibitors of PD-1/PD-L1. Based on these studies, we believe that activation of the innate immune system by APX005M in combination with cabiralizumab will enhance the activity of nivolumab, leading to a novel therapeutic approach for the increasing population of cancer patients who progress on currently approved immune checkpoint inhibitors. This is the first time this combination of drugs has been given to patients and we are eager to initiate this new clinical trial,” said Harriet Kluger, M.D., Professor of Medicine at Yale Cancer Center and Principal Investigator of the trial.

 

DIAGNOSTIC ASSAY

“PD-L1 is a critical biomarker for identifying patients who are likely to derive benefit from anti-PD-1 immunotherapy, and with an increasingly complex marketplace, pathologists look to Agilent as the clear leader to provide accurate and reliable PD-L1 testing,” said Sam Raha, president of Agilent’s Diagnostics and Genomics Group. “This expansion of use for the Dako PD-L1 IHC 22C3 pharmDx assay gives patients with cervical cancer the possibility of having their tumor sample tested for PD-L1 expression, and determining eligibility for treatment with KEYTRUDA.”

Infographically Speaking….

Cover image: (Wikimedia Commons) This scanning electron micrograph (SEM) depicted a number of red blood cells found enmeshed in a fibrinous matrix on the luminal surface of an indwelling vascular catheter; Magnified 2858x. Note the biconcave cytomorphologic shape of each erythrocyte, which increases the surface area of these hemoglobin-filled cells, thereby, promoting a greater degree of gas exchange, which is their primary function in an in vivo setting. In their adult phase, these cells possess no nucleus. What appears to be irregularly-shaped chunks of debris, are actually fibrin clumps, which when inside the living organism, functions as a key component in the process of blood clot formation, acting to entrap the red blood cells in a mesh-like latticework of proteinaceous strands, thereby, stabilizing and strengthening the clot, in much the same way as rebar acts to strengthen, and reinforce cement.
