New findings show OXC-101 may be effective against allergic asthma

OXC-101 is under development for cancer treatment as the main indication, but data suggest that it may also have an effect in autoimmune T-cell driven diseases. Earlier in the year we reported on the promising data for psoriasis. Now, promising effects of OXC-101 in allergic asthma have recently been reported.

One of the most common chronic inflammatory airway diseases is asthma, affecting around 300 million individuals worldwide. There is still a need for new pharmacological approaches to modulate the dysregulated airway inflammation in allergic asthma, not least to avoid side-effects of corticosteroids. OXC-101, a mitotic MTH1 inhibitor, has previously been shown to affect activated T cells- which orchestrate allergic inflammation.

In collaboration with Professor Arne Egesten and his team, OXC-101 was investigated in models of allergic airway inflammation. The study and results,  “Pharmacological inhibition of MutT homolog 1 (MTH1) in allergic airway inflammation as a novel treatment strategy”, have now been published in the prestigious journal “Respiratory Research”  ( Adler et al. Respiratory Research (2025) 26:101 https://doi.org/10.1186/s12931-025-03175-z). The study showed that MTH1 inhibition reduced proliferation and promoted apoptosis of T cells in vitro. Furthermore, OXC-101 dampened the type 2 associated immune response and reduced the allergic airway inflammation in a murine model. These findings suggest that MTH1 could serve as a novel target to treat also allergic airway inflammation.

OXC-201, Oxcia’s candidate for inflammation and fibrosis, has also demonstrated efficacy for allergic airway inflammation. OXC-201 inhibits OGG1, a DNA repair enzyme, i.e. 8-oxoguanine DNA glycosylase-1 and thereby reduce inflammation and bronchial hyperreactivity. The anti-inflammatory effect achieved by inhibition of MTH1 is mediated through a completely different mechanism.

The positive data underlines the versatility of Oxcia's technology platform, O2-DDR (short for Oxidative stress, Oxidative DNA damage and DNA damage response (DDR)).

Briefly about Oxcia AB
Oxcia’s aim is to improve and extend lives by developing new innovative treatments based on our unique technology platform, O2-DDR. Oxcia AB is a pioneer in oxidative DNA damage and DNA Damage Response (DDR – the processes the body uses to repair the damage that occurs to DNA) with a focus on developing new safe and effective treatments for patients suffering from diseases caused by cancer or inflammation. Oxcia currently has two O2-DDR lead drug candidates, both with the potential to become first-in-class drugs. OXC-101 is in early clinical development as novel cancer therapy. OXC-201 is developed against idiopathic pulmonary fibrosis, and is in the preclinical phase. The portfolio also includes exploratory projects, e.g in psoriasis.
