Oslo, Norway, 22 August 2019

Nordic Nanovector ASA (OSE: NANO) announces its results for the second quarter
and first half 2019. A presentation by the company's senior management team will
take place today in Oslo at 08:30 CEST, see details below.

Eduardo Bravo, CEO, commented: "We continue to progress our clinical development
programmes with Betalutin® in major NHL indications. In PARADIGME, we have
reached our target range in terms of activated sites and while the recruitment
rate has accelerated in recent months, this has not been at the rate we
anticipated. This has led us to reassess the trial timelines and we now estimate
to complete patient enrolment in 2H 2020 rather than 1H 2020 as previously
guided. We would expect the data read-out from the trial a few months after the
final patient has been dosed. As a one-off treatment, Betalutin® has an exciting
product profile, and we have been encouraged by the preliminary analysis of the
extended median duration of response data that we have disclosed today. We
remain focused on advancing PARADIGME and our other clinical programmes as
quickly as possible given the clear benefits that Betalutin® could deliver to
NHL patients around the globe."

Upcoming R&D Day

Nordic Nanovector is planning to host and R&D Day in September. During the event
the senior management team and external speakers will provide updates and
further information on the company's key activities. The R&D Day will take place
in Oslo and will also be webcast live. Details on the date and how to register
to attend will be announced within the next two weeks.

Outlook

Nordic Nanovector aspires to become a leader in the field of targeted therapies
for haematological cancers by developing, manufacturing and commercialising
innovative therapies to address major unmet medical needs and advance cancer
care.

Betalutin®, the company's most advanced product candidate, has a highly
differentiated, competitive, clinical profile for recurrent FL, based on the
promising results from the LYMRIT 37-01 Phase 1/2 clinical trial. The company's
pivotal Phase 2b PARADIGME trial with a once-only administration of Betalutin®
in 3L R/R FL is underway. Patient enrolment is expected to be completed in the
second half of 2020. A data read-out is expected a few months after the final
patient is dosed enabling filing for marketing approval in the first half of
2021.

The company maintains its guidance that current cash resources are expected to
be sufficient to reach mid-2020.

Nordic Nanovector intends to maximize the value of Betalutin® across the major
types of NHL (FL and DLBCL) and in earlier treatment lines in combination with
standard treatments. The company is also evaluating opportunities with other
CD37-targeting radioimmunotherapies and antibody drug conjugates across NHL and
other haematological cancer indications.

The company is confident that Betalutin® could become an attractive and
convenient therapeutic option, which, based on detailed market research, has the
potential to be commercially successful.
