ImmunoINSIGHTS Global multi-year MSA Signed with Top 10 Pharmaceutical Group

Further ImmunoINSIGHTS Commercial Contracts Signed

Oncimmune Holdings plc (AIM: ONC.L), the leading global immunodiagnostics group, is pleased to announce the signing of a number of new ImmunoINSIGHTS contracts.

Subsequent to the announcement made on 14 December 2022, in which the Company stated it had signed further ImmunoINSIGHTS contracts with an existing global pharmaceutical client, Oncimmune now confirms that it has signed a Master Services Agreement ("MSA") with a new top 10 pharmaceutical group for the provision of ImmunoINSIGHTS clinical laboratory services. The MSA is expected to support multiple autoantibody profiling projects which are currently in discussion, focusing on autoimmune, cardiovascular and prenatal diseases. This multi-year MSA has been awarded following an assessment by the client of Oncimmune's ImmunoINSIGHTS autoantibody profiling platform in autoimmune disease patient samples.

The Company has also signed a new contract with a leading UK-based biotech company to collaborate on the discovery of autoantibody biomarkers for the detection of sepsis. All intellectual property rights ("IP") developed during the collaboration shall be owned exclusively by Oncimmune. On completion of this initial contract, the biotech company shall have the option to extend the collaboration to a verification study on commercial terms with Oncimmune and to take-up an option to enter into a 20-year agreement to licence from the Company the IP generated from the collaboration in consideration for an upfront payment and an ongoing royalty payment.

The Company has also signed a new commercial contract with a leading US research institution to analyse samples and generate autoantibody profiles in serum in patients with confirmed Glioblastoma Multiforme.

Whilst the signing of these new contracts does not change the Company's current revenue guidance for the 12 months to 31 August 2023, as outlined in the announcement made on 7 December 2022, these signed contracts, together with other recently announced contracts, and those which are in contract finalisation, give the Board continued confidence in the outlook for the business.
