ADOCIA is a clinical-stage biotechnology company that specializes in the development of innovative formulations of therapeutic proteins and peptides for the treatment of diabetes, obesity and metabolic diseases. In the diabetes field, Adocia’s portfolio of injectable treatments is among the largest and most differentiated of the industry, featuring five clinical-stage products and several pre-clinical products. The proprietary BioChaperone® technological platform is designed to enhance the effectiveness and/or safety of therapeutic proteins while making them easier for patients to use.

The clinical pipeline also includes an aqueous formulation of human glucagon (BioChaperone® Glucagon) for the treatment of hypoglycemia.

Adocia’s preclinical pipeline for diabetes treatment includes bi-hormonal combinations: two combinations of rapid acting insulin analogs and Pramlintide (BioChaperone® Lispro Pram and BioChaperone® Aspart Pram), and a combination of insulin glargine with GLP-1 receptor agonists (BioChaperone® Glargine Liraglutide).

Adocia recently added a cell therapy initiative focused on development of a hydrogel scaffold for use in people with type 1 diabetes. The first patent application supporting this program has been filed.

Adocia’s preclinical pipeline for the treatment of obesity includes two bi-hormonal products: a combination of glucagon and exenatide (BioChaperone® Glucagon Exenatide) and a combination of pramlintide and exenatide (PramExe).
