Combined General Meeting of August 17, 2022: Onxeo Shareholders Approve Withdrawal From the Nasdaq First North Market in Copenhagen

Company to submit delisting request to Nasdaq

PARIS--(BUSINESS WIRE)-- Regulatory News:

Onxeo S.A. (Euronext Growth: ALONX, Nasdaq First North: ONXEO), a clinical-stage biotechnology company specializing in the development of innovative drugs targeting tumor DNA Damage Response (DDR) in particular against rare or resistant forms of cancer, today announced that the Combined General Meeting held today has adopted all the resolutions presented in line with the recommendations of the Board of Directors.

In particular, the shareholders approved the delisting of the Company's shares on the Nasdaq First North market in Copenhagen and granted all powers to the Board of Directors to carry out the delisting.

The company will in the coming days formally request and ask for approval of the delisting of the company shares from trading on the Nasdaq First North from the Danish stock exchange operator.

After approval by the market operator the effective delisting of Onxeo shares from the Nasdaq First North market is expected to take place after an additional period of 10 weeks.

The company is contemplating to arrange for the automatic exchange of securities in order that Danish shareholders will be able to trade their Onxeo shares on Euronext Growth, with the same ISIN code (FR0010095596). No change will be made to the number of ordinary shares or to the rights attached to Onxeo shares and the shares will continue to be traded on Euronext Growth Paris. The share capital of the Company will therefore remain unchanged. The company will provide further details when an approval for the delisting has been obtained from Nasdaq First North.

For further information, shareholders are invited to consult the Frequently asked questions relating to the withdrawal of the Company from the Nasdaq First North market in Copenhagen, available on the Company's website, in the General Meetings section. The result of the votes by resolution and the minutes of the meeting will be available there within the legal deadlines.

About Onxeo

Onxeo (Euronext Paris, NASDAQ Copenhagen: ONXEO) is a clinical-stage biotechnology company developing innovative oncology drugs targeting tumor DNA-binding functions through unique mechanisms of action in the sought-after field of DNA Damage Response (DDR). The Company is focused on bringing early-stage first-in-class or disruptive compounds from translational research to clinical proof-of-concept, a value-creating inflection point appealing to potential partners.

platON is Onxeo’s proprietary chemistry platform of oligonucleotides acting as decoy agonists, which generates new innovative compounds and broaden the Company’s product pipeline.

AsiDNA, the first compound from platON, is a highly differentiated, clinical-stage first-in-class candidate in the field of DNA damage response (DDR) applied to oncology. Its decoy and agonist mechanism acting upstream of multiple DDR pathways results in distinctive antitumor properties, including the ability to prevent or abrogate tumor resistance to targeted therapies such as PARP inhibitors and strong synergy with tumor DNA-damaging agents such as radio-chemotherapy. AsiDNA is currently being studied in Europe in combination with other treatment modalities in difficult-to-treat solid tumors.

OX400 is a series of new drug candidates from platON, designed to be a next-generation PARP inhibitor acting on both the DNA Damage Response and the activation of immune response, without inducing resistance. The lead OX400 candidate is currently being optimized and is undergoing preclinical proof-of-concept studies, alone and in combination with immunotherapies.
