NORDIC NANOVECTOR ASA FIRST QUARTER 2016 RESULTS: STRONG PROGRESS ON ALL PRIORITIES AND EXECUTION ON TRACK

Oslo, Norway, 19 May 2016

Nordic Nanovector ASA (OSE: NANO) announces its results for the first quarter 2016. A presentation of the results by the company’s senior management team will take place today at 8:30 a.m. CEST in Oslo – details below.

Nordic Nanovector reports steady operational progress on Betalutin®’s clinical development plan in Follicular Lymphoma (FL), with recruitment of both sites and patients proceeding according to schedule. The Lymrit 37-01 study is on track to define the optimized dose regimen to be used in PARADIGME, the pivotal Phase 2 study planned to start in 2H 2017. Updated data from this ongoing clinical study, presented at the American Association of Cancer Research (AACR) in April, confirm Betalutin®’s efficacy potential, durability of response and favourable safety profile in patients with advanced FL.

The company continues to advance its product pipeline. Having received clearance of the Investigational New Drug (IND) Application from the FDA and acceptance of the protocol design from EU Authorities, Nordic Nanovector is ready to initiate its Phase 1 clinical study for Betalutin® in diffuse large B cell lymphoma (DLBCL). Other progresses include the research and development collaboration with Paul Scherrer Institute, aiming at developing new Antibody-Radionuclide-Conjugates (ARCs) for treatment of single cell leukaemias. During the first quarter, the company received a grant of up to NOK 15 million from the Research Council of Norway’s User-driven Research-based Innovation programme to support the discovery and development of novel targeted therapeutics for leukaemia and NHL.

Luigi Costa, CEO of Nordic Nanovector, comments: “We are pleased to report that our operations are progressing according to plan and on track to meet milestones. The updated results from Betalutin® in FL are promising and reinforce our belief in its promise to become a significant new treatment of NHL. We have also made good progress across all key areas, including the initiation of a clinical study for Betalutin® in a second NHL indication, with a significant unmet medical need, and promising preclinical research highlighting further opportunities for our pipeline.”

Nordic Nanovector is a biotech company focusing on the development and commercialisation 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-Radionuclide-Conjugates (ARC) designed to improve upon and complement current options for the treatment of non-Hodgkin 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 tumour-seeking anti-CD37 antibody (HH1) conjugated to a low intensity radionuclide (lutetium-177). The preliminary data has shown promising efficacy and safety profile in an ongoing Phase 1/2 study in a difficult-to-treat NHL patient population. The Company is aiming at developing Betalutin® for the treatment of major types of NHL with first regulatory submission anticipated in 1H 2019.

Nordic Nanovector intends to retain marketing rights and to actively participate in the commercialisation of Betalutin® in core markets, while exploring potential distribution agreements in selected geographies.
