Seattle Genetics and Agensys Announce Co-Development of Antibody-Drug Conjugate
News Jul 01, 2013
The ADC, called ASG-15ME, targets the tumor antigen SLITRK6, which is known to be expressed on bladder and lung cancer. Agensys has submitted an investigational new drug (IND) application to the U.S. Food and Drug Administration (FDA) for a phase 1 trial of ASG-15ME.
“Through our collaboration and co-development agreements with companies like Agensys/Astellas, Seattle Genetics continues to enhance its ability to innovate by combining our industry-leading ADC technology with proprietary cancer targets and antibodies to develop potential new treatments for patients with cancer,” said Eric L. Dobmeier, Chief Operating Officer of Seattle Genetics. “ADCs represent a novel therapeutic approach, and through our pipeline and collaborations more than half of the ADC candidates in clinical development utilize our technology. We look forward to working with Agensys/Astellas to advance ASG-15ME.”
“We’re eager to continue our strong collaboration with Seattle Genetics for ASG-15ME,” said David Stover, Ph.D., Senior Vice President, Agensys Site Head. “This collaboration with Seattle Genetics is in line with our goal to utilize the most advanced technologies to generate more innovative medicines in oncology.”
ASG-15ME is an ADC composed of a fully human antibody directed to SLITRK6, an antigen expressed in multiple solid tumors. Preclinically, ASG-15ME has demonstrated antitumor activity in models of bladder and lung cancer. The antibody is attached to a potent, synthetic cytotoxic agent, monomethyl auristatin E (MMAE), via an enzyme-cleavable linker using Seattle Genetics’ proprietary technology. The ADC is designed to be stable in the bloodstream, but to release MMAE upon internalization into SLITRK6-expressing tumor cells, resulting in targeted cell-killing.
Human Malaria Parasites Grown for the First Time in Dormant FormNews
One of the biggest obstacles to eradicating malaria is a dormant form of the parasite which is resistant to most antimalarial drugs and can reawaken years later, causing disease relapse. Researchers have shown they can grow the dormant parasite in engineered human liver tissue for several weeks, allowing them to closely study how the parasite becomes dormant, what vulnerabilities it may have, and how it springs back to life.READ MORE
Gut Bacteria Latest Ally in Fight Against SepsisNews
Sepsis occurs when the body's response to the spread of bacteria or toxins to the bloodstream damages tissues and organs. The fight against sepsis could get a helping hand from a surprising source: gut bacteria. Researchers found that giving mice particular microbes increased blood levels of immunoglobulin A (IgA) antibodies, which protected against the kind of widespread bacterial invasion that leads to sepsis.READ MORE
