Oslo, Norway, 3 May 2022
Nordic Nanovector ASA (OSE: NANOV), a clinical-stage biotech company focused on
CD37-targeted therapies for haematological cancers and immune diseases,
announces the publication of two new research papers highlighting approaches to
improve the potential therapeutic effect of its novel CD37-targeting
radioimmunoconjugate Humalutin® ([177]Lu-DOTA-NNV003) in B-cell malignancies,
such as Non-Hodgkin Lymphoma (NHL).
The first publication by the Company’s scientists and its collaborators,
published in PLOS One (Ref. 1), reports on the combined effect of Humalutin®
with olaparib, a member of the class of anticancer therapies known as PARP
inhibitors, on NHL cell lines.
In the studies, the combination of Humalutin® and olaparib was found to be
synergistic or conditionally synergistic leading to cell death in 6 of 7 NHL
cell lines (diffuse large B cell lymphoma and mantle cell lymphoma). Where the
combination was conditionally synergistic (i.e. both synergistic and
antagonistic), the effect was dependent on the concentration of each drug,
showing the importance of optimising the parameters for further studies.
Humalutin® acts by inducing potentially cytotoxic DNA breaks in the NHL cells,
sensitising these cells to olaparib, which prevents the repair of DNA breaks by
blocking the activity of DNA repair enzymes poly (ADP ribose) polymerase 1 and 2
(PARP1 and PARP2). Olaparib is approved in the US and most markets globally for
BRCA mutated ovarian and breast cancer.
The authors concluded that further in vivo studies evaluating the anti-tumour
effect of the combination of radioimmunotherapies, including Humalutin®, and
PARP inhibition are warranted.
Separately, Nordic Nanovector reports the publication of a paper in the high
-impact open access journal Scientific Reports (Ref. 2) on the potential of a
non-invasive diagnostic imaging approach to select NHL patients who are more
likely to respond to or are at risk for developing CD37-induced haematological
toxicities from CD37-targeted radioimmunotherapy.
The imaging approach used a radioimmunoconjugate ([[89]Zr]Zr-N-sucDf-NNV003)
comprising the Company’s proprietary anti-CD37 antibody NNV003 (a component of
Humalutin®), and zirconium-89, a radioisotope that is well-suited to commonly
used positron emission tomography (PET) imaging, to assess CD37-expression,
biodistribution and tumour-uptake levels in mice bearing human B cell lymphomas
and to predict the possible therapeutic effects of Humalutin® in NHL patients.
A good manufacturing practice (GMP)-compliant production process has also been
established to enable administration to patients in future studies.
Jostein Dahle, Nordic Nanovector’s Chief Scientific Officer, said: “These two
publications add to the growing scientific evidence supporting CD37 as a
valuable tumour target both for therapeutic and diagnostic applications in NHL.
This evidence provides important validation of our pipeline approach, building
on the significant data we have collected from our preclinical and clinical
studies with Betalutin® and now expanding to our next-generation CD37-targeting
radioimmunoconjugate Humalutin®. We look forward to continuing to grow our
understanding around CD37 and the potential of our emerging pipeline.”

About Nordic Nanovector:
Nordic Nanovector is committed to develop and deliver innovative therapies to
patients to address major unmet medical needs. The Company aspires to become a
leader in the development of CD37-targeted therapies for haematological cancers
and immune diseases. Nordic Nanovector’s lead clinical-stage candidate is
Betalutin®, a novel CD37-targeting antibody-radionuclide-conjugate designed to
advance the treatment of non-Hodgkin’s lymphoma (NHL). NHL is an indication with
substantial unmet medical need, representing a growing market forecast to be
worth nearly USD 26 billion by 2028. Nordic Nanovector retains global marketing
rights to Betalutin® and intends to actively participate in the
commercialisation of Betalutin® in the US and other major markets.
