About Oxford BioTherapeutics
Oxford BioTherapeutics specializes in discovering and developing first-in-class antibody-based therapies aimed at meeting significant patient needs in cancer treatment. Their focus on Bispecific Antibodies and Antibody Drug Conjugate (ADC) therapeutics reflects a commitment to advancing oncology care.
The OGAP-Verify platform, characterized by its enhanced sensitivity and reliability, accelerates the biopharma industry’s capacity to identify and validate human targets. Currently, OBT boasts three programs based on OGAP technology in clinical development across the United States and Europe.
Clinical Developments and Future Endeavors
OBT's lead clinical program, OBT076, began expansion in a US clinical trial in 2021 aimed at patients with advanced solid tumors, including gastric, bladder, ovarian, and lung cancer. The drug's efficacy is particularly notable in tumors where CD205 is overexpressed, targeting the infiltration of immunosuppressive cells that hinder cancer treatment efficacy.
The company’s pipeline has gained validation through partnerships with industry giants such as Roche, Boehringer Ingelheim, and Zymeworks, among others.
