Arctic Bioscience announces encouraging top-line results from the HeROPA clinical study

The HeROPA phase 2b study in mild-to-moderate psoriasis show encouraging results

on key secondary endpoint with increasing durable efficacy up to week 52.

Data analyses are ongoing for the full Clinical Study Report. The company will

hold a presentation with the full set of data from the study when the Clinical

Study Report is ready in June, including statistical significance levels for all

datapoints and relevant sub-analyses.

Among patients who completed 52 weeks of treatment:

· More patients treated with HRO350 achieved "clear" or "almost clear" skin

(PGA 0/1) indicating minimal or no skin symptoms in both active groups compared

to placebo

· In the full population (PASI 3-10 at inclusion), 46 % of patients treated

with high dose achieved a PGA 0/1 versus 36 % in the placebo group

· In the group of patients with PASI 6-10 at inclusion, 45 % of patients in

the high dose group achieved a PGA 0/1 versus 29 % in the placebo group

· 50 % reduction in the Psoriasis Area and Severity index (PASI50):

· As was observed for the 6-month readout of this endpoint, the placebo rate

is high which obscures differences between the groups

· HRO350 was well tolerated throughout the study duration with no new safety

concerns and no unexpected serious adverse events

PGA 0/1 is commonly used as a primary endpoint in studies, is a treatment-goal

for psoriasis and is a harder endpoint to reach than a 50 % reduction in PASI

(PASI50).

The Company is funded to expected cash flow positive nutra operations in 2026.

Further development of the HRO350 in mild-to-moderate psoriasis, beyond the

current phase 2b, will be funded separately through partnerships or specific

project funding.

About the HeROPA study and HRO350:

The HeROPA trial was randomized, double blind and placebo controlled and

investigated the efficacy and safety of two doses of the novel, oral drug

candidate HRO350 versus placebo for the treatment of mild-to-moderate psoriasis.

The HeROPA trial has been conducted in 5 countries in Europe: UK, Germany,

Poland, Finland and Norway (EU-CT-2022-501850-12-00). HRO350 contains a first-in

-class API (PeHeRo) with a mode-of-action differing from other oral treatment

options under development.

Further supporting the data on clinical efficacy of HRO350 in this phase 2b

clinical trial, Arctic Bioscience have presented data on the effects of HRO350

on skin cells and immune cells, including on SPMs in line with an anti

-inflammatory effect in the skin at international congresses. Two publications

are in peer-review process.
