Boehringer Ingelheim has released new findings from its Beamion LUNG-1 trial, highlighting the potential of zongertinib as a breakthrough oral therapy for patients with advanced non-small cell lung cancer (NSCLC) harboring HER2 mutations.

The trial focused on patients with advanced NSCLC who had previously received treatment and whose tumors carry activating HER2 mutations, particularly in the tyrosine kinase domain, according to the company. Among the 75 patients evaluated, the objective response rate was 71%, including a 7% complete response rate and a 64% partial response rate. The disease control rate reached 96%, with median duration of response at 14.1 months and median progression-free survival at 12.4 months, it says.

“This trial suggests zongertinib may offer a new approach to treating patients with non-small cell lung cancer with activating HER2 mutations,” said study investigator and MD Anderson Cancer Center’s rhoracic/head and neck medical oncology chair John Heymach. “More than 70% of patients experienced a tumor response, which is highly meaningful. If approved, zongertinib would be the first oral, targeted treatment option for this subgroup.”

Zongertinib also demonstrated intracranial activity, with 41% of 27 evaluable patients with brain metastases responding to treatment and 81% achieving disease control, the company says.
