Andecaliximab ELISA Kit

Andecaliximab (formerly GS-5745; Gilead Sciences, Inc.), a recombinant chimeric IgG4 monoclonal antibody (mAb), was engineered to remove T-cell epitopes to reduce immunogenicity risk. Andecaliximab selectively binds and inhibits matrix metalloproteinase-9 (MMP9) with minimal cross-reactivity to other matrix metalloproteinases, including the highly homologous matrix metalloproteinase-2 (MMP-2) . Andecaliximab is under development for the treatment of cystic fibrosis, gastric cancer, pancreatic cancer, non-small cell lung cancer (NSCLC), rheumatoid arthritis (RA), Crohn's disease (CD), and ulcerative colitis (UC) . In a recent phase 1 dose-escalation study in patients with UC, andecaliximab had good tolerability and was associated with a numerically greater percentage of clinical, endoscopic, and histological responses in patients relative to placebo over a 5-week treatment period. A phase 2/3 trial, evaluating the safety and efficacy of andecaliximab to induce and maintain clinical remission in patients with moderate to severe UC, was initiated. A planned interim futility analysis following an 8-week induction period in the first 150 patients resulted in the termination of the study due to lack of efficacy.

The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 10% prior to the expiration date under appropriate storage condition.
