A Phase II Trial OF Carboplatin, ABI-007 (Abraxane) And Sorafenib (BAY 43-9006) in Metastatic Melanoma

The primary objective of this phase II multicenter trial is to:

Measure the response rate (RR) of this combination and schedule in patients with metastatic
melanoma

The secondary objectives are to:

Assess the safety and toxicity of this regimen in this patient population

Determine the 1-year and median PFS of patients treated according to protocol

Determine overall survival (OS)

STUDY DESIGN

This will be a Phase II study single arm study with a two-stage design with a maximum sample
size of 43 patients, 18 in the first stage and 25 in the second stage.

Study duration: A minimum yearly accrual of 10-15 patients/institution is expected.
Therefore, to reach the first stage, the study will take 1.2 to 1.8 years with one
institution, 0.6 to 0.9 years with 2 institutions, and 0.4 to 0.6 years with 3. If the study
continues to full accrual to 43 patients, completion will take 2.9 to 4.3 years with one
institution, 1.4 to 2.2 years with two and 0.96 to 1.43 years with three institutions.

Inclusion Criteria:

- Histologically confirmed diagnosis of melanoma with measurable disease

- Patients with stage IV, previously untreated, refractory to initial therapy or
progressing after response to initial therapy

- Patients with unresectable stage III, including unresectable in-transit metastases

- Two prior chemotherapy regimen is allowed

- One prior immunotherapy regimen is allowed

- No other concurrent investigational therapy

- Radiation therapy to non-target lesions or to one of multiple target lesions may be
allowed on a case-by-case basis

- Patients must be past the nadir from previous cytotoxic therapy

- Age at least 18 years

- ECOG performance status 0-2

- Hemoglobin > 9.0 g/dl, absolute neutrophil count (ANC) > 1,500/mm3, platelet count >
100,000/mm3

- Total bilirubin within normal limits, ALT and AST < 2.0 x the ULN ( < 5 x ULN for
patients with liver involvement), INR < 1.5 and aPTT within normal limits. Patients
who receive anti-coagulation treatment with an agent such as warfarin or heparin may
be allowed to participate. For patients on warfarin, close monitoring of at least
weekly evaluations will be performed until INR is stable based on a measurement at pre
dose, as defined by the local standard of care.

- Creatinine < 1.5 x ULN, serum calcium within normal limits

- Patients with stable brain metastasis who have been treated with either whole brain
radiation or Gamma Knife and have been off steroids for > 4 weeks

- Women of childbearing potential and men must agree to use adequate contraception
(barrier method of birth control) prior to study entry and for the duration of study
participation. Men and women should use adequate birth control for at least three
months after the last administration of protocol drugs. Women of childbearing
potential must have a negative serum pregnancy test performed within 7 days prior to
the start of treatment.

- Ability to understand and sign a written informed consent document. All patients must
have a signed informed consent before registration and initiation of therapy

Exclusion Criteria:

- Cardiac disease: Congestive heart failure > class II NYHA.

- Patients must not have unstable angina (anginal symptoms at rest) or new onset angina
(began within the last 3 months) or myocardial infarction within the past 6 months.

- Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.

- Uncontrolled hypertension defined as systolic blood pressure > 150 mmHg or diastolic
pressure > 90 mmHg, despite optimal medical management.

- No known severe hypersensitivity or suspected allergy to sorafenib, ABI-007 or any of
the excipients

- Patients with neurological symptoms must undergo a CT scan/MRI of the brain to exclude
progressing brain metastasis.

- Peripheral neuropathy greater than grade II

- Serious intercurrent medical or psychiatric illness, including serious active
infection

- Known human immunodeficiency virus (HIV) infection or chronic Hepatitis B or C.

- Thrombotic or embolic events such as a cerebrovascular accident including transient
ischemic attacks within the past 6 months.

- Pulmonary hemorrhage/bleeding event > CTCAE Grade 2 within 4 weeks of first dose of
study drug.

- Any other hemorrhage/bleeding event > CTCAE Grade 3 within 4 weeks of first dose of
study drug.

- Serious non-healing wound, ulcer, or bone fracture.

- Evidence or history of bleeding diathesis or coagulopathy

- Major surgery, open biopsy or significant traumatic injury within 4 weeks of first
study drug.

- Use of St. John's Wort or rifampin (rifampicin)

- Any condition that impairs patient's ability to swallow whole pills.

- Any malabsorption problem

- No treatment for melanoma within the previous 4 weeks.
