Substantial contract win for Proteome Sciences

London, December 20, 2021. Proteome Sciences is pleased to announce that the Company has secured a contract in excess of GBP 1 million from a major pharmaceutical company to analyse large cohorts of clinical samples from a phase 3 clinical trial. Work is expected to start early in the first quarter of 2022 and the majority of revenue is expected to be generated in 2022.

Commenting on the contract, Richard Dennis, Chief Commercial Officer of Proteome Sciences said:

"We are delighted that Proteome Sciences has been selected as the biomarker CRO of choice for these ongoing clinical studies. The contract will take up a significant part of the expanded capacity that we have added to our services activities in 2022 and into 2023. Our proprietary proteomics services using Tandem Mass Tags (TMTpro) was key to selecting Proteome Sciences as was the intellectual property in our TMTcalibrator technique to boost the sensitivity of mass spectrometry in their selected sample types."
