# A2 Biotherapeutics > A2 Biotherapeutics (A2 Bio) is a clinical-stage biotechnology company in Agoura Hills, California, > founded in 2018 by Alexander Kamb, Michael Gallo and Paul Kang. It develops logic-gated cell > therapies for solid tumors built on its proprietary Tmod™ platform, which uses a two-receptor > activator/blocker design so a T cell attacks tumor cells that have lost an HLA allele while sparing > normal cells that retain it. A2 Bio publishes no developer product API. This file describes the > only live API surface it operates: the WordPress REST API of its corporate website, which also > fronts two OAuth-gated Model Context Protocol servers.
