About the DARPin® Difference

DARPin® therapeutics are a new class of protein therapeutics that open an extra dimension of multi-specificity and multi-functionality. DARPin® candidates are potent, specific, safe and very versatile. They can engage more than five targets at once, offering potential benefits over those provided by conventional monoclonal antibodies or other currently available protein therapeutics.

The DARPin® technology is a fast and cost-effective drug discovery engine, producing drug candidates with ideal properties for development and very high production yields. With their good safety profile, low immunogenicity and long half-life in the bloodstream and the eye, DARPin® therapies have the potential to advance modern medicine and significantly improve the treatment of serious diseases, including cancer and sight-threatening disorders. Molecular Partners is partnering with Allergan to advance clinical programs in ophthalmology and is advancing a proprietary pipeline of DARPin® drug candidates in oncology. The most advanced global product candidate is abicipar, a molecule currently in phase 3, in partnership with Allergan. Several DARPin® molecules for various ophthalmic indications are also in development. The most advanced systemic DARPin® molecule, MP0250, is in a clinical POC study in multiple myeloma. In addition, Molecular Partners will evaluate MP0250 for the treatment of solid tumors in a phase 1b/2 trial in patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC). MP0274, the company’s second-most advanced DARPin® drug candidate in oncology, has entered into phase 1 clinical development. With its broad anti-HER activity, MP0274 inhibits HER1-, HER2-, and HER3-mediated downstream signaling via Her2, leading to induction of apoptosis. Molecular Partners is also advancing a growing preclinical pipeline that features several immuno-oncological development programs. DARPin® is a registered trademark owned by Molecular Partners AG.
