About Nordic Nanovector
Nordic Nanovector is a biotech company focusing on the development and commercialization of novel targeted therapeutics in haematology and oncology. The Company's lead clinical-stage product opportunity is Betalutin™, the first in a new class of Antibody-Radio-Conjugates (ARCs), designed to improve upon and complement current options for the treatment of Non-Hodgkin's Lymphoma (NHL). NHL is an indication with substantial unmet medical need and orphan drug opportunities, representing a growing market worth over $12 billion by 2018.

Betalutin™ comprises a tumor-seeking anti-CD37 antibody conjugated to low intensity radionuclide (Lutetium 177). It has shown promising efficacy in Phase 1 studies in a difficult-to-treat NHL patient population and as well as a very favourable tolerability. Betalutin™ is fast advancing through clinical development and with first approval anticipated in 2018.

Nordic Nanovector intends to retain marketing rights and to actively participate in the commercialization of Betalutin™ in core markets, while exploring potential distribution agreements in selected geographies. The Company is committed to developing its ARC pipeline to treat a number of select cancer indications.
