A Study to Test How Well Different Doses of BI 3706674 Are Tolerated by People With Advanced Cancer in the Stomach and Oesophagus

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.
✓. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
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
2
Part B: Occurrence of drug-related adverse events (AEs) ≥ Common Terminology Criteria for Adverse Events (CTCAE) Grade 3 during the on-treatment period
Timeframe: up to 3.5 years
3
Part C: Objective response (OR) based on central assessment
. All toxicities related to previous anti-cancer therapies have resolved ≤ CTCAE Grade 1 prior to trial treatment administration (except for alopecia and peripheral neuropathy which must be ≤ CTCAE Grade 2 and amenorrhea/menstrual disorders which can be any grade).
✓. Life expectancy ≥3 months at the start of treatment in the opinion of the investigator.
✓. Age ≥18 years of age, or over the legal age of consent as required by local legislation.
