After announcing a phase 3 launch based on positive midstage results, iTeos and GSK are finally sharing the highlights from the phase 2 TIGIT trial, revealing a more than 30% difference in confirmed overall response rates between the investigational treatment versus monotherapy.

The results of the GALAXIES Lung-02 study reported at the ESMO congress in Barcelona showed that the drug – added to GSK's PD-1 inhibitor Jemperli (dostarlimab) – achieved a higher objective response rate than Jemperli on its own.

A targeted immunotherapy being developed by iTeos Therapeutics and GSK, it was reported at #ESMO, delivered promising response rates in patients with a type of lung cancer.

The published belrestotug/dostarlimab data is still too immature to prove the combination’s capability to disrupt the NSCLC treatment paradigm.

Results presented at ESMO showed tumor response rates that matched the bar set by analysts for success. But they may not yet be enough to dispel doubts around TIGIT as a target.

Teos Therapeutics (NASDAQ:ITOS) announced Saturday that its experimental cancer doublet therapy developed with GSK (NYSE:GSK) outperformed the British drugmaker’s FDA-approved anti-PD-1 therapy dostarlimab,

Early data from GSK Plc and iTeos Therapeutics’ mid-stage trial of a lung cancer medicine looks set to renew cautious optimism around a class of immunotherapy drugs that has suffered a series of setbacks.
