Oncimmune Holdings PLC said Thursday that it has signed a new contract with Swiss pharmaceutical giant Roche Holding AG to profile autoantibodies in patient samples collected during cancer immunotherapy trials.

The U.K. immunodiagnostics group said the contract, for the use of Oncimmune's SeroTag biomarker discovery platform to explore autoantibody profiles in patients that received cancer immunotherapy, will start immediately. Initial results are scheduled to be provided to Roche within three months, with project completion by November, Oncimmune said.

Oncimmune Chief Executive Adam M Hill said this is the largest contract the company has signed to date and builds upon the collaborative work between the two companies in recent months.
