Paclitaxel Albumin-Stabilized Nanoparticle Formulation and Bevacizumab in Treating Patients with Stage IV Melanoma, Gynecologic Cancers, and Other Malignancies that Cannot be Removed by Surgery


About this study

This phase I trial studies the side effects and best dose of paclitaxel albumin-stabilized nanoparticle formulation and bevacizumab in treating patients with stage IV melanoma, gynecological cancers, or other malignancies that cannot be removed by surgery. Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving paclitaxel albumin-stabilized nanoparticle formulation and bevacizumab may kill more tumor cells.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:
