ClinConnect Summary

The Beamion BCGC-1 trial is looking at a new treatment option for adults with specific types of advanced HER2-positive cancer, including metastatic breast cancer and certain gastric cancers that have spread and cannot be surgically removed. The study aims to find the best dose of a drug called zongertinib when used alongside two other drugs, trastuzumab deruxtecan and trastuzumab emtansine. Researchers want to see if this combination can help shrink tumors in patients whose previous treatments didn’t work.

To participate, individuals must be at least 18 years old and have a documented diagnosis of HER2-positive cancer that has progressed. They should also have measurable tumors and be recovering well from any previous treatments. During the trial, participants will regularly visit the study site for health checks and imaging tests to monitor their tumors and any side effects. This study is currently recruiting, and it offers a chance to explore a potential new treatment for those who have few options left.

Eligibility criteria

• Inclusion Criteria:
• • Signed and dated written Informed consent form (ICF) in accordance with International Council for Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial.
• • Patients ≥18 years of age or over the legal age of consent in countries where that is greater than 18 years at the time of signature of the ICF.
• • Documented Human epidermal growth factor receptor 2 overexpressing and/or amplified (HER2+), metastatic breast cancer (mBC) or metastatic gastric adenocarcinoma, gastroesophageal junction adenocarcinoma, or esophageal adenocarcinoma (mGEAC).
• • For dose optimization (Phase II): Patient must provide tumor tissue from locations not radiated prior to biopsy, if possible, collected through archival tissue.
• • Documented investigator assessed progression.
• • Recovered from any previous therapy-related toxicity to ≤ Common Terminology Criteria for Adverse Events (CTCAE) Grade 1 at start of treatment (except for alopecia, stable sensory neuropathy, and hypothyroidism (patients on thyroid replacement therapy) which must be ≤ CTCAE Grade 2).
• • Presence of at least one measurable lesion according to Response evaluation criteria in solid tumors (RECIST) 1.1, as determined by the local site investigator/radiology assessment.
• • Eastern Cooperative Oncology Group (ECOG) score of 0 or 1. Further inclusion criteria apply.
• Exclusion Criteria:
• * Previous or concomitant malignancies other than the one treated in this trial within the previous 2 years, which require current systemic therapy except:
• • effectively treated non-melanoma skin cancers
• • effectively treated carcinoma in situ of the cervix
• • effectively treated ductal carcinoma in situ
• • other effectively treated malignancy that is considered cured by local treatment
• • History or presence of cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure New York Heart Association (NYHA) classification of ≥ III or IV, unstable angina or poorly controlled arrhythmia which are considered as clinically relevant by the investigator. Myocardial infarction (or troponin levels consistent with myocardial infarction within 28 days of randomization), stroke, or pulmonary embolism within 6 months prior to randomization.
• • Any clinically important abnormalities (as assessed by the investigator) in rhythm, conduction, or morphology of resting electrocardiograms, e.g. complete left bundle branch block, third degree heart block.
• • 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.
• • Women who are pregnant or nursing or who plan to become pregnant or nurse during the trial or within 7 months after the last dose of trial treatment with T-DXd, T-DM1, trastuzumab or capecitabine and trastuzumab.
• • Further exclusion criteria apply.
