A Study to Test How Well Different Doses of BI 3706674 Are Tolerated by People With Advanced Cancer in the Stomach and Oesophagus
United States, Japan, South Korea47 participantsStarted 2023-12-06
Plain-language summary
This study is no longer open to new participants. It was a study in adults with advanced cancer in the stomach and oesophagus. This is a study for people for whom previous treatment was not successful or no treatment exists. In this study, BI 3706674 is given to humans for the first time.
The purpose of this study is to find a suitable dose of BI 3706674 that people with advanced cancer can tolerate when taken alone. Another purpose is to check whether BI 3706674 can make tumours shrink. BI 3706674 blocks growth signals and may prevent the tumour from growing.
Participants take BI 3706674 as a tablet when starting treatment. Different doses of BI 3706674 are tested during this study. If there is benefit for the participants and if they can tolerate it, the treatment is given up to the maximum duration of the study. During this time, participants visit the study site regularly. The total number of visits depends on how they respond to and tolerate the treatment. Doctors record any unwanted effects and regularly check the general health of the participants.

Inclusion criteria
. Patients with pathologically confirmed diagnosis of locally advanced or metastatic gastric adenocarcinoma (GAC), oesophageal adenocarcinomas (EAC), and gastroesophageal junction adenocarcinoma (GEJAC) with Kirsten rat sarcoma viral oncogene homolog (KRAS) wild type (wt) amplification and documented disease progression despite at least 1 line of prior therapy. KRAS status will be confirmed retrospectively for those with a known KRAS status or determined prospectively (dose confirmation and expansion) if KRAS status is unknown, using archival tissue (if available) or a fresh biopsy.
. Patients who have failed conventional treatment or for whom no therapy of proven efficacy exists or who are not eligible for established treatment options.
. Dose confirmation (Part B) only: Patient is willing and able to undergo mandatory pre- and on-treatment low risk tumour biopsies. Patients with a high risk for biopsy complications can be included without undergoing pre- and on-treatment tumour biopsy as long as archival tumour tissue is available for confirmation of KRAS status.
. At least one target lesion that can be measured per RECIST version 1.1 (radiated lesions do not qualify as target lesions unless there has been demonstrated progression of the lesion after completion of radiotherapy) Dose escalation (Part A) only: Patients with no lesions measurable per RECIST version 1.1 may be included if agreed between Sponsor and investigator.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Part A: Occurrence of dose limiting toxicities (DLTs) in the maximum tolerated dose (MTD) evaluation period
Timeframe: up to 28 days
