This is a study for people with advanced cancer for whom previous treatment was not successful. Adults aged 18 and over with advanced cancer with HER2 alterations can join the study. The purpose of this study is to find out whether a medicine called zongertinib helps people with advanced cancers with HER2 alterations. HER2 alterations can cause cancer. Zongertinib inhibits HER2.
Participants are put into groups based on the type of advanced cancer they have, the type of HER2 alterations they have, and the dose of zongertinib they receive. Depending on the group they are in, participants take 1 of 2 different doses of zongertinib each day. Participants can continue the treatment as long as they benefit from it and can tolerate it.
Participants visit the study site regularly. During many of the visits, the doctors check the size of the tumour and whether it has spread to other parts of the body. During all the visits, the doctors check participants' health and take note of any unwanted effects.
Patients aged ≥18 years
Documented Human epidermal growth factor receptor 2 (HER2)-positive status or known activating HER2 mutations (by local testing)
Histologically or cytologically confirmed locally advanced, unresectable, or metastatic solid tumours
Disease progression following prior treatment in the metastatic setting (including treatment with antibody-drug conjugates (ADCs)) and no suitable standard of care treatment options
Diagnosis of HER2-positive (overexpressed/amplified) metastatic breast cancer or metastatic gastroesophageal adenocarcinoma
Diagnosis of HER2-mutant non-small cell lung cancer (NSCLC)
Previous treatment with any HER2 tyrosine kinase inhibitors (TKIs)
Previous or concomitant malignancies other than the one treated in this trial within the previous 3 years except the following effectively treated cancers: nonmelanoma skin cancers, carcinoma in situ of the cervix, ductal carcinoma in situ of the breast, localized prostate cancer on watchful waiting or active surveillance, and other effectively treated malignancies that are considered cured by local treatment

DrugZongertinib
Proportion of patients with objective response (OR)
according to Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 by central independent review, and it will be summarised descriptively as absolute and relative frequencies
Duration of objective response (DOR)
Duration of objective response (DOR) is defined as the time from first documented Objective response (OR) according to RECIST 1.1 until the earliest date of disease progression or death among patients with confirmed OR, assessed by central independent review.
Progression-Free Survival (PFS)
PFS is defined as the time from treatment start until the earliest date of tumour progression according to RECIST 1.1 assessed by central independent review, or death from any cause, whichever occurs first.
Disease control (DC)
Disease control (DC) is defined as best overall response (BOR) of complete response (CR) or partial response (PR) or stable disease (SD) where BOR is defined according to RECIST 1.1 from first treatment administration until the earliest of disease progression, death, or last evaluable tumour assessment before the start of subsequent anti-cancer therapy, or treatment discontinuation, as assessed by central independent review.
