35To determine the efficacy as measured by objective tumor response of first-line treatment of metastatic melanoma with bevacizumab monotherapy
In Norway, cutaneous malignant melanoma is the second most frequent and the most frequent cancer type in middle-aged (30-54 years) females and males, respectively, and the incidence has six-doubled during the last 30 years. Median survival for patients with metastatic melanoma is 6 months.
Many agents have been investigated for anti-tumor effect in melanoma, but there is no accepted standard therapy. Biochemotherapy, combining cytotoxic drugs with Interleukin-2 or Interferon alpha, has not been shown to be superior to single agent Dacarbazine (DTIC), which is regarded to be the most active agent. Other biological approaches like vaccination are currently under investigation, but still no efficient treatment for metastatic melanoma is available. DTIC induces objective remission in 20% of the patients, but without significant impact on survival.
The need of a new and effective treatment for the group of melanoma patients is urgently needed. This will be the first study to assess response rates of bevacizumab monotherapy in first line treatment of metastatic melanoma. In addition there will be a major focus on the identification of predictive biomarkers of bevacizumab efficacy.
Anti angiogenesis treatment
LEVEL A (second line): after confirmed progression on standard first line treatment with dacarbazine. LEVEL B (first line): when objective clinical response is observed in LEVEL A, patients will be included for first line treatment with bevacizumab Inclusion Criteria: Histologically confirmed metastatic (unresectable) melanoma and with progressive disease WHO performance status 0-2 Age >18 years Able to undergo outpatient treatment Patients must have clinically and/or radiographically documented measurable disease according to RECIST criteria At least 4 weeks since adjuvant interferon alpha Recovered from prior chemotherapy Major surgical procedure or significant traumatic injury within 28 days prior to study treatment start. Biopsy or fine needle aspiration within 5 days prior to study treatment start. Central venous line placement must be inserted at least 5 days prior to treatment start. Minimum required laboratory data: Hematology: absolute granulocytes > 1.0 x 109/L platelets > 100 x 109/L Biochemistry: bilirubin < 1.5 x upper normal limit serum creatinine within normal limits INR < 1.5 Before patient registration/randomization, written informed consent must be given according to national and local regulations. Exclusion Criteria: No pregnant or lactating patients can be included No prior interferon alpha or IL-2 for metastatic disease No more than 1 prior chemotherapy regimen for metastatic disease No clinical evidence of coagulopathy No brain metastases No symptomatic congestive heart failure No unstable angina pectoris No cardiac arrhythmia No history of thrombosis No full-dose oral coumarin-derived anticoagulants (INR>1.5) or heparin, thrombolytic agents, or chronic, daily treatment with aspirin (>325 mg/day) No non-steroidal anti-inflammatory medications (those known to inhibit platelet function at doses used to treat chronic inflammatory diseases) No uncontrolled hypertension Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
