Analytical Chemist located in Solna

Oncopeptides is a global biotech company focused on the development of targeted therapies for difficult-to-treat hematological diseases. The U.S. Food and Drug Administration has recently granted PEPAXTO (melphalan flufenamide, also known as melflufen), accelerated approval in relapsed or refractory multiple myeloma. Melphalan flufenamide is the first drug originated from the Company´s proprietary PDC-platform and is evaluated in a comprehensive clinical study program, including the ongoing phase 3 OCEAN study. Melphalan flufenamide is the first anticancer peptide-drug conjugate for patients with relapsed or refractory multiple myeloma. The drug uses innovative technology that links a peptide carrier to a cytotoxic agent, resulting in a lipophilic compound. Due to its high lipophilicity, it is distributed into the cells. Melphalan flufenamide is designed to leverage aminopeptidases, enzymes which are overexpressed in myeloma cells and cause the release of the cytotoxic agents in the cells.

Oncopeptides’ global Headquarters is based in Stockholm, Sweden and the U.S. Headquarters is situated in Boston, Mass. The company is listed in the Mid Cap segment on Nasdaq Stockholm with the ticker ONCO. Today the company consists of 250+ co-workers in Europe and USA.
