Rituxan and Abraxane for the Treatment of Patients With Inoperable Stage III and IV Malignant Melanoma

• Patients must have inoperable stage III and IV melanoma.

Patients will be included in the trial based on the following criteria:

Patients previously treated with no more than 1 non-abraxane containing chemotherapy regimen or patients with the B-Raf mutation, who have received vemurafenib or the combination of Dabrafinib and trametinib (or similar compound on clinical trial) and progressed, who have documented surgically inoperable stage III or IV metastatic melanoma on pathologic examination of tissue. Previous treatment with immunotherapy is allowed. Patients who have been treated with either immunotherapy or chemotherapy must have be either 4 weeks from their last treatment or have fully recovered from all previous treatment.

Measurable or evaluable non-CNS disease required as defined:

• Uni-dimensionally measurable lesion as determined by physical exam, X-ray, CT scan, MRI, or other radiographic procedure.
• Lesion that can be seen on a radiologic test but is not uni-dimensionally measurable
• Previously irradiated lesion allowed only with documentation of progression if no other metastatic site present.

No active brain metastases Patients with previously treated brain metastases that have responded to therapy will be allowed on study assuming there is measurable disease outside of the CNS. Active therapy for the CNS disease must be completed a minimum of 3 weeks for chemotherapy and 6 weeks for radiation therapy (prior to enrollment on this study).

Prior/ Concurrent therapy

Biologic therapy No concurrent biological therapy with the exception of growth factors for anemia, neutropenia or thrombocytopenia.
