-based drugs. Using a proprietary technology platform, Peptides-to-Drugs (P2D), Jerini pursued disease indications for which limited, inadequate, or no treatment options exist. As a result, Jerini established a drug pipeline composed of its own programs as well as others in collaboration with partners. Jerini's commercialization strategy was to market new drugs in niche indications independently and in larger indications with partners. Jerini was acquired by

(AMD), the leading cause of vision loss and blindness in people over the age of 55 in developed countries. Jerini's compound (JSM 6427) has shown significant efficacy in combating disease progression in preclinical models. Jerini's proprietary Peptides-to-Drugs (P2D) technology was used to identify peptide drug lead structures and systematically transform them into peptidomimetic (injectable) and small-molecule (oral) drugs, depending on the indication. This enabled Jerini to develop novel drug candidates for diseases that were difficult to access using traditional drug discovery methods. The ability to produce both peptidomimetics and small molecule drugs as drug candidates has enabled the simultaneous development of drugs for acute and chronic treatments against the same target molecule (target).
