Uveal Melanoma, Metastatic

The goal of this clinical trial is to learn if a low dose of dexamethasone can prevent cytokine release syndrome in participants treated with tebentafusp for advanced uveal melanoma. The main questions the study aims to answer are: How many participants get cytokine release syndrome? How severe is the cytokine release syndrome? What other side effects happen due to dexamethasone and/or tebentafusp? Participants will be treated with tebentafusp per standard practices. For this study, participants will receive dexamethasone before infusion of the first 4 doses of tebentafusp. Participants will have visits for checkups and tests at the time they are given the medications and 9 weeks after they started. Other visits will be approximately every 6 months for at least 2 years and can be done in person or remotely (telehealth).

The Phase I trial is evaluating safety, tolerability, pharmacokinetics and preliminary efficacy of MBS8(1V270) in subjects with advanced solid tumours. The trial is designed to provide data for further clinical development of MBS8(1V270)

This is a combination study of Tebentafusp and the PI3Kdelta inhibitor, Roginolisib

This study is being done to find the best dose of an investigational drug called NBM-BMX for people with metastatic uveal melanoma, a type of eye cancer that has spread to other parts of the body. The study will help doctors learn about the side effects of NBM-BMX, how the drug is processed in the body, and whether it may slow down or shrink tumors. Participants will take NBM-BMX as a capsule by mouth twice daily on an empty stomach with at least six ounces (180 mL) of water. No food or drink (other than water) should be consumed for at least two hours after each dose. Participants will visit the clinic about once every week or two for exams and blood tests while taking NBM-BMX. After stopping treatment, a follow-up visit will occur about 30 days later. Treatment may continue as long as the cancer does not get worse and side effects remain manageable.
