(Alliance News) - GSK PLC on Tuesday said it is ending the development programme for monoclonal antibody belrestotug.

Shares in GSK were down 1.3% to 1,381.00 pence in London on Tuesday afternoon.

The London-based pharmaceutical company said belrestotug is an anti-TIGIT monoclonal antibody it was developing alongside partner iTeos Therpaeutics Inc.

GSK said the decision to end the development is based on interim analyses from the phase 2 Galaxies Lung-201 and H&N-202 studies, which "did not meet the established efficacy criteria for continued development".

It said the collaboration and all belrestotug-containing study cohorts are ending as a result.

The drug was being developed as a potential treatment for various cancers.

GSK said it is expanding from its current focus on blood and women's cancers into lung and gastrointestinal cancers, as well as other solid tumours.
