On March 30, 2019 Maverick Therapeutics Inc., a private biopharmaceutical company pioneering next-generation redirected T-cell targeted immunotherapies, reported that it will unveil pre-clinical data characterizing its novel COBRATM therapeutic platform at the upcoming American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2019 being held from March 29 to April 3 in Atlanta, Georgia (Press release, Maverick Therapeutics, MAR 30, 2019, View Source [SID1234534787]). COBRA is the most advanced bispecific T-cell engaging platform in its class, designed to safely target solid tumors with highly specific and potent activity. These pre-clinical data characterize the conditional and potent activity of the COBRATM platform in vitro as well as demonstrate the regression of established solid tumors in in vivo models.

COBRATM is a proprietary approach to cancer immunotherapy. The COBRATM molecules are designed to bind to a specific target but are engineered to activate only after they enter the tumor microenvironment, allowing for specific T-cell engagement and activation at the site of the cancer. Focusing T-cell activation and killing at the tumor site is ideal for the treatment of solid tumors, which account for 90% of all cancers1. COBRATM molecules include a component that extends their half-life in the circulation prior to activation within the tumor site; once activated, this component is lost, allowing the active molecules to then be cleared from the body more rapidly after targeting and killing the cancer cells. This further increases their safety window by reducing the potential for active COBRATM molecules to travel outside the tumor to healthy tissues and cause damage.

"We are encouraged by the inaugural data on our proprietary COBRATM platform, as they provide proof-of-concept for our approach to overcome the challenges current T-cell engagers face when addressing solid tumors," said Maverick Therapeutics Chief Executive Officer Jim Scibetta. "With its scientifically elegant design, COBRATM has the potential to deliver increased specificity, higher potency and reduced toxicity, all of which may help extend both the duration and quality of life of people living with solid tumor cancers."

About COBRA Therapeutic Platform

The company’s proprietary COBRA, or COnditional Bispecific Redirected Activation, therapeutic platform is the most advanced bispecific T-cell engagement platform, designed to target solid tumors with highly potent and specific activity, while avoiding damage to normal healthy tissues. COBRATM molecules are designed to bind to a specific target, but are engineered to activate only after they enter the tumor microenvironment, allowing for specific T-cell engagement and activation at the site of the cancer. COBRATM molecules include a component that extends their presence in the circulation prior to activation within the tumor site; once activated this component is lost, allowing the active molecule to then be cleared from the body more rapidly after targeting and killing the cancer cells. This increases their safety window by reducing the potential for active COBRA molecules to escape the tumor and travel to healthy tissues.
