Beamion 44: A Study to Test How Well Zongertinib is Tolerated by People With Advanced Non-small Cell Lung Cancer With HER2 Mutations When Given in Combination With Chemotherapy With or Without Pembrolizumab

Summary

This study is open to adults with a type of lung cancer called HER2-mutant non-squamous non-small cell lung cancer (NSCLC) that is advanced or has spread. People who have a tumor with a HER2 mutation and have not received previous treatment for their lung cancer can participate in the study. The purpose of this study is to find out how well a medicine called zongertinib is tolerated in people with this type of lung cancer, when combined with chemotherapy, with or without pembrolizumab. Zongertinib works by targeting and blocking HER2, a protein involved in cancer cell growth. Participants are put into two groups randomly, which means by chance. One group gets zongertinib tablets combined with platinum-based chemotherapy. The other group gets the same treatment plus an additional medicine called pembrolizumab. Chemotherapy and pembrolizumab are given as an infusion into a vein. Participants take zongertinib by mouth once a day, while chemotherapy is given every 3 weeks for up to 3 months, followed by maintenance treatment for up to 2 years. Pembrolizumab is given every 3 weeks for up to 2 years. This study does not have a fixed duration. Participants can receive some of the study treatments for up to about 2 years and may continue to take zongertinib as long as they benefit from treatment and can tolerate it. During this time, they visit the study site regularly. Doctors regularly check the size of the tumor and whether it has spread. They also monitor participants' health and take note of any unwanted effects.

3. Documented activating human epidermal growth factor receptor 2 (HER2) mutation as per existing local lab result
4. An archival tumor tissue sample must be submitted to the central laboratory after randomization to retrospectively confirm the HER2 status
5. Patients who have not received any systemic treatment for unresectable, locally advanced or metastatic disease
6. Presence of at least one measurable non-Central Nervous System (CNS) lesion according to response evaluation criteria in solid tumors (RECIST) 1.1

Exclusion criteria:

1. Tumors with targetable alterations with approved available therapy
2. Presence or history of leptomeningeal disease
3. Radiotherapy within 4 weeks prior to treatment start with exception of palliative radiotherapy to regions other than the chest if completed at least 2 weeks prior to treatment start
4. Major surgery (major according to the investigator's assessment) performed within 4 weeks prior to randomization or planned within 6 months after screening
5. Any history of or concomitant condition that, in the opinion of the investigator, would compromise the patient's ability to comply with the trial or interfere with the evaluation of the safety and efficacy of the test drug
6. Previous therapy with a HER2-directed agent
7. History or presence of cardiovascular abnormalities which are considered as clinically relevant by the investigator. Myocardial infarction, stroke, or pulmonary embolism within 6 months prior to randomization Further exclusion criteria apply.
