A Study to Learn How Safe BAY2666605 is, How it Affects the Body, How it Moves Into, Through and Out of the Body, the Maximum Amount That Can be Given and Its Action Against Tumors in Adult Participants With Skin Cancer That Has Spread to Other Part

• Status: Recruiting
• Trial end date: 2024-06-25

Summary

Researchers are looking for a better way to treat people who have advanced cancer. In this study researchers want to learn more about a new substance called BAY2666605. BAY2666605 triggers the formation of a complex of two proteins called SLFN12 and PDE3A. This complex drive cancer cells into cell death by a mechanism called apoptosis. The complex is only formed in the cancers which contain both proteins. This study is done in adult patients who have certain types of advanced cancers that cannot be cured by drugs that are currently available. The cancer types include skin cancer that has spread to other parts of the body and cancer that started in the bones or soft tissue, the ovaries, or the brain. Patients with these cancers are only included if the cells of the patient's cancer contain the building plan to produce SLFN12-phosphodiesterase 3A (PDE3A) complex. To confirm this, a specific test is performed with the cancer cells. The researchers will study how BAY2666605 moves into, through and out of the body. Researchers will try to find the best dose that can be given, how safe BAY2666605 is and how it affects the body. Researchers will also study the action of BAY2666605 against the cancer. Part A will include about 36 participants and up to another 12 participants. Part B will include about 41 participants. All of the participants will take BAY2666605 by mouth as either a liquid or as tablets. During the study, the participants will take the treatment in 4 week periods called cycles. In each cycle, the participants will in general take BAY2666605 once daily. The participants may also be asked to do overnight fasting before the intake of substance and to have standard high-fat, high-calorie breakfast on some days before taking the dose. These 4 week cycles will be repeated throughout the trial. The participants can take BAY2666605 until their cancer gets worse, until they have medical problems, or until they leave the trial. Participants will have around 18 visits in each cycle. Some of the visits can also be done via Phone. During the trial, the study team will take blood and urine samples, do physical examinations and check the participants' heart health using an electrocardiogram (ECG) and an ultrasound of the heart. The study team will also take pictures of the participants' tumors using CT or MRI scans. The study team will ask how the participants are feeling, if participants have any medical problems or if participants are taking any other medicine. About 1 month and 3 months after the last dose, the participants will have another visit and a phone call respectively where participants will be checked for and asked about medical problems. The researchers will then contact the participants every 3 months until the trial ends.
