A Study to Learn More About How Well Treatment With Sevabertinib (BAY 2927088) Tablets Works and How Safe it is in Participants Who Have a Solid Tumor With Mutations of the Human Epidermal Growth Factor Receptor 2 (HER2)
(panSOHO)
What this study is about
Researchers are looking for a better way to treat people who have solid tumors with HER2-activating mutations. Before a treatment can be approved for people to take, researchers do clinical trials to better understand its safety and how it works. In this trial, the researchers want to learn how well BAY2927088 (sevabertinib) works in people with different types of solid tumors with HER2 mutations.

Primary outcome measures
Objective Response Rate (ORR) per RECIST 1.1 as assessed by BICR
Time frame: From start of study intervention until the first documented progression, or death from any cause, or end of study (up to approximately 3 years), whichever comes first
ORR is defined as the proportion of participants with a best overall response of confirmed complete response (CR) or partial response (PR) per RECIST 1.1 by BICR. CR is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have decreased in size to have a short axis of \<10 mm. PR is defined as a ≥30% decrease in the sum of diameters of target lesions taking as reference the baseline sum of diameters. RECIST 1.1 = Response Evaluation Criteria in Solid Tumors, version 1.1; BICR = blinded independent central review (BICR)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
