研究概览
简要总结
The goal of this clinical research study is to find the highest tolerable dose of pomalidomide that can be given in combination with melphalan and dexamethasone that can be given to patients with AL amyloidosis. The safety of this drug combination will also be studied.
Pomalidomide is designed to change the body's immune system. It may also interfere with the development of tiny blood vessels that help support tumor growth. This may decrease the growth of cancer cells.
Melphalan is designed to damage the DNA (genetic material) of cells, which may cause cancer cells to die.
Dexamethasone is a corticosteroid that is similar to a natural hormone made by your body. Dexamethasone is often given to Multiple Myeloma (MM) patients in combination with other chemotherapy to treat cancer.
Planned Phase I/II Study terminated early during Phase I portion without continuation to Phase II.
详细描述
Study Groups:
If you are found to be eligible to take part in this study, you will be assigned to a dose level of pomalidomide, based on when you join this study. Up to 4 dose levels of pomalidomide will be tested for the Phase I portion of this study. Up to 30 participants will be enrolled at each dose level in the Phase I portion, and up to 24 participants will be enrolled in Phase II. The first group of participants will receive the lowest dose level. Each new group will receive a higher dose than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of pomalidomide is found.
If you are enrolled in the Phase II portion, you will receive pomalidomide at the highest dose that was tolerated in the Phase I portion.
All participants will receive the same dose level of dexamethasone and melphalan. If intolerable side effects are seen at the lowest dose level, then the melphalan dose will be lowered.
After 2 cycles of therapy, you may be referred to a transplant specialist, if you are eligible for a stem cell transplant.
