Brief summary
This study is open to adults aged 18 years and older with different types of HER2+ cancer that has spread and cannot be removed by surgery. People can take part in this study if their tumours show HER2 aberrations and previous treatment was not successful. The purpose of this study is to find a suitable dose of zongertinib that people with different types of HER2+ cancer that has spread can tolerate best when taken together with trastuzumab deruxtecan (T-DXd), with trastuzumab emtansine (T-DM1), with trastuzumab and capecitabine, with zanidatamab, or with mFOLFOX6 (with or without trastuzumab). Another purpose is to check whether zongertinib alone and in combination with other treatments can make tumours shrink. Zongertinib inhibits HER2. HER2 causes cancer cells to grow. In this study, participants receive treatment in cycles. Study participants are treated with zongertinib alone or in combination with other treatments. This study has 2 parts. In Part 1, participants in different groups receive increasing doses of zongertinib. In Part 2, participants are put into different groups by chance. Each group receives a different dose of zongertinib. Every participant has an equal chance of being in each group. During the study, the participants visit the study site regularly. In this study, researchers want to find the highest dose of zongertinib that participants can tolerate when taken together with other treatments. To find this out, researchers look at certain severe health problems that a number of participants have. The doctors regularly check the size of the tumour with imaging methods (CT/MRI) during the study. The doctors also regularly check participants' health and take note of any unwanted effects.

Eligibility
Inclusion criteria

Patients must have had at least one prior line of therapy for locally advanced unresectable disease or metastatic disease (adjuvant and neoadjuvant therapy excluded) and documented disease progression or recurrence of disease during or following their latest line of therapy. In the opinion of the Investigator, patients must be unlikely to tolerate or derive clinically meaningful benefit from further standard of care therapy known to prolong survival. * Presence of at least one measurable lesion according to RECIST 1.1 * Eastern Cooperative Oncology Group (ECOG) score of 0 or 1 * Adequate organ function based on laboratory values Further inclusion criteria apply.
Exclusion criteria
* Previous treatment with: * Any small molecule HER2 inhibitor in the palliative setting in Cohorts D, E, F, H, L, L-ext, M, and N. In Cohort D allowed in up to 15 patients in each dose level (DL). * T-DXd in Cohorts E and F. In Cohort E allowed in up to 15 patients in each DL. * trastuzumab emtansine (T-DM1) in the palliative setting in Cohort D and H. In Cohort H allowed in up to 15 patients in each DL. * Capecitabine in Cohort D and H. In Cohort D allowed in up to 15 patients in each DL * Presence of uncontrolled and/or symptomatic brain metastases, or leptomeningeal disease * Mean resting corrected QT interval (QT interval corrected for heart rate by Fridericia´s formula (QTcF)) \>470 msec. * Any factors that increase the risk of QT interval corrected for heart rate (QTc) prolongation or risk of arrhythmic events such as heart failure, hypokalemia, congenital long QT syndrome, personal or family history of long QT syndrome or unexplained sudden death under 40 years-of-age. * Ejection fraction \<50% or the lower limit of normal of the institutional standard within 28 days prior to randomization * History of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required steroids, current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening Further
Design outcomes

| Dose escalation (Phase Ib): Occurrence of dose-limiting toxicities (DLTs) in the maximum tolerated dose (MTD) evaluation period | up to 21 days | The MTD evaluation period is defined as the first 21 days of the first treatment cycle for Cohorts A, B, C, G, K, and O. The MTD evaluation period is defined as the first 28 days after the first administration of any trial medication for Cohorts M and N. |
| Dose optimization and justification (Phase II): Objective response (OR) | up to 50 months | Objective response (OR) is defined as the best overall response of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST 1.1 from the date of treatment start until the earliest date of disease progression, death, or last evaluable tumor assessment before start of subsequent anti-cancer therapy, or treatment discontinuation as assessed by investigator review. |
