BI 894999 First in Human Dose Finding Study in Advanced Malignancies

• Status: Active, not recruiting
• Trial end date: 2021-12-15
• Target enrollment: 0
• Participant gender: All

Summary

This study is open to adults with different types of advanced cancer (solid tumours). The study is also open to patients with diffuse large B-cell lymphoma in whom previous treatment was not successful. In some countries, adolescents who are at least 15 years old and who are diagnosed with NUT carcinoma can also participate. No standard treatment exists for this rare and aggressive form of cancer.

The purpose of this study is to find out the highest dose of BI 894999 that people can tolerate.

BI 894999 is tested for the first time in humans. Participants take tablets once daily. The study also tests whether participants can tolerate BI 894999 better when taken continuously or with breaks in between.

Participants can stay in the study as long as they benefit from the treatment and can tolerate it.

The doctors also regularly check the general health of the participants.

• Phase: Phase 1

Criteria

Inclusion criteria:

For all patients

• Age 18 years or older at the time of signature of the informed consent.

• Life expectancy of at least 12 weeks after the start of the treatment according to the investigator's judgement

• Male or female patients. Women of childbearing potential* must be ready and able to use highly effective methods of birth control per ICH M3(R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the patient information. For women of childbearing potential using a contraceptive pill, an additional barrier method is necessary due to the potential CYP3A4 inducing effect of BI894999. Male patients having a partner of childbearing potential must use condoms and ensure their partner is using a highly effective method of birth control as described above, during the trial and for at least three months after the end of the trial * Any female who has experienced menarche and does not meet the criteria for "women not of childbearing potential" as described below.

Women not of childbearing potential are defined as: women who are postmenopausal (12 months with no menses without an alternative medical cause) or who are permanently sterilized (e.g., tubal occlusion, hysterectomy, bilateral oophorectomy or bilateral salpingectomy).
