Nordic Nanovector announces an open Investigational New Drug application for new clinical study of Betalutin® in diffuse large B-cell lymphoma

Clinical development programme expected to start in 2H 2016

Oslo, Norway, 9 May 2016

Nordic Nanovector ASA (OSE: NANO), a biotechnology company focusing on the development of novel targeted therapeutics in haematology and oncology, announces that its Investigational New Drug (IND) application for a new Phase 1 clinical study of Betalutin® in a second non-Hodgkin lymphoma (NHL) indication is now open with the US Food & Drug Administration (FDA).

The Company plans to investigate Betalutin® in relapsed diffuse large B-cell lymphoma (DLBCL) patients who are ineligible for stem cell transplant. This represents the most prevalent relapsed DLBCL patient population and the one with the greatest unmet medical need.

The Phase 1 dose-finding study (Lymrit 37-05) has a classical 3+3 dose-escalation design and is expected to enrol up to 24 patients in the US and Europe. The study is designed to identify an optimal dose regimen of Betalutin® in patients pre-dosed with unconjugated “cold” HH1 anti-CD37 antibody to take into Phase 2.

In approving the IND, FDA requested that an additional 3+3 cohort be included at the start of the study to investigate a regimen involving an intermediate pre-dose of cold HH1 prior to Betalutin® injection in the DLBCL population.

The study protocol without the latest adjustments made to meet FDA’s requests has already been approved by the appropriate EU regulatory authorities, via the Voluntary Harmonisation Procedure. 

Nordic Nanovector intends to adopt the FDA requested amendment also in Europe and plans to initiate the application process for the amended design with the relevant EU regulators as soon as possible. Pending approval of the amended design, the Company now expects the first DLBCL patient to be enrolled and treated in 2H 2016 compared to 1H 2016 as previously communicated.

Luigi Costa, Nordic Nanovector CEO, commented: “We are encouraged by FDA’s response to our IND, and intend to make the recommended amendment that will allow us to conduct our first study in DLBCL patients in both the US and Europe. We will work with EU regulators to expedite approval of the revised study design in Europe so that we can prepare and start patient recruitment in the second half of 2016. This is an important further step forward in the development of Betalutin®, data for which continue to highlight its potential to become a relevant new treatment of B-cell malignancies.”

About DLBCL

DLBCL is an aggressive form of NHL that accounts for 36-43% of all NHL cases, making it the most common form of the disease (ref.1). It occurs most frequently in a population aged >50 years (average age 62 years). Immediate combination chemotherapy treatment is essential and the tumour is potentially curable.

The value of the DLBCL market (across all lines of therapy) in the seven major markets (US, EU-5 and Japan), exceeds USD 1.8 billion (mostly driven by sales of rituximab and chemotherapy drugs). The market  is estimated to grow to USD 4.7 billion by 2024 as a result of novel immuno-oncology treatments and combination approaches in development in the relapsed setting (ref. 1). 

Approximately 40% of DLBCL patients relapse following treatment with rituximab-chemotherapy (R-CHOP) in first line. In the seven key markets this equates to 21,200 patients. Only 30-40% of relapsed patients respond with subsequent high-dose chemotherapy followed by stem cell transplant (SCT) (ref. 2).  Patients ineligible for SCT (12,720-14,840) have a very short life expectancy as available therapeutic options are limited and ineffective. This is one of the highest unmet medical need in Non-Hodgkin’s Lymphoma.

About Nordic Nanovector

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. The Company is committed to developing its ARC pipeline to treat multiple selected cancer indications.
