BioNTech (BNTX) and OncoC4 said Saturday that their experimental therapy, gotistobart, showed a "meaningful" overall survival benefit in certain metastatic squamous non-small cell lung cancer patients during the non-pivotal stage of the global phase 3 trial.
The study included 45 patients receiving gotistobart monotherapy and 42 patients receiving chemotherapy, or docetaxel.
At 12 months, overall survival rate was 63% for gotistobart versus 30% for chemotherapy. At a median follow-up of 14.5 months, patients in the gotistobart treatment arm had not yet reached the median overall survival, while the docetaxel arm achieved a median overall survival of 10 months.
Gotistobart reduced the risk of death by 54% compared with chemotherapy, the companies said.
The pivotal stage of the phase 3 trial is ongoing at more than 160 sites globally.
BioNTech shares were up 3.2% in recent premarket activity Monday.
