A phase II trial of nab-paclitaxel (ABI-007) and carboplatin in patients with unresectable stage IV melanoma

9055 Background: There is increasing evidence that paclitaxel and carboplatin are clinically active in the treatment of metastatic melanoma (MM). Nab-P is an albumin-bound paclitaxel with ability to bind SPARC (secreted protein acid rich in cysteine), that is overexpressed in MM and associated with poor prognosis. This study explores the clinical activity of the combination of nab-P and C in patients (pts) with stage IV melanoma and SPARC correlatives. Methods: A parallel phase II trial was conducted in pts with unresectable stage IV melanoma, who were either chemotherapy naïve (CN) or were previously treated (PT). A treatment regimen consisting of nab-P (100 mg/m2) and C (AUC 2) was administered on days 1, 8, and 15 of a 28 day cycle. The primary aim of this study was to assess whether tumor response rate (CR + PR by RECIST) was ≤15% vs ≥35% in the CN group and ≤5% vs ≥ 20% in the PT cohort. Major eligibility criteria: ≥18 years of age, ECOG PS ≤2, adequate organ function, platinum or taxane naive, peripheral neuropathy < grade 2, and no untreated brain metastasis; no pregnant and/or nursing women. Tumor tissue was tested for SPARC and level 3 immunohistochemical staining was considered positive. Results: 76 pts (41-CN and 35 PT) enrolled from 11/2006 - 7/2007, 3 pts (2-CN, 1-PT) cancelled prior to starting treatment. The median number of cycles administered was 4 (range 1–18-CN and 1–10-PT). There were 11 (28.2%) confirmed responses (1 CR and 10 PRs) in the CN cohort (90% CI: 16.7–42.3%) and 3 (8.8%) confirmed responses (3 PRs) in the PT cohort (90% CI: 2.5–21.3%). Median PFS was 4.5 months (CN) and 4.1 months (PT). Median OS was 11.1 months (CN) and 10.9 months (PT).The most common severe toxicities in both groups (CTCAE ≥ grade 3) included neutropenia, thrombocytopenia, neuro-sensory, fatigue, nausea, and vomiting. PFS was not affected by SPARC positivity; however, based on limited data there is some evidence that OS may be longer with tumoral SPARC positivity (10.0 vs 12.8 mo; SPARC negative vs SPARC positive). Conclusions: The weekly combination of nab-P and C appears to be well tolerated with promising clinical activity as front line or salvage therapy in pts with MM. SPARC positivity may be associated with improved OS. No significant financial relationships to disclose.

8560 Background: In patients with metastatic melanoma, the combination of chemotherapy with an agent that specifically targets vascular endothelial growth factor (VEGF) might be able to control tumor growth and progression much more effectively than chemotherapy alone. Methods: A two-stage phase II clinical trial was conducted in patients with unresectable stage IV melanoma to assess the anti-tumor activity and toxicity profile of the combination of paclitaxel (80 mg/m2 IV on days 1, 8 and 15 of a 28-day cycle), carboplatin (AUC = 6 IV on day 1) and bevacizumab (10 mg/kg IV on days 1 and 15). The primary end point of the study was the 8-week progression-free survival rate (PFS). Enrollment to the second stage of the study was opened if 8 or more of the first 20 patients enrolled remained progression-free at 8 weeks. Eligible patients had measurable disease by RECIST criteria, a performance status (PS) of 0–2 and acceptable pre-registration organ function. Exclusion criteria included: brain metastases, significant recent bleeding, uncontrolled hypertension and ongoing anticoagulation. The study opened in February 2006 and completed full study accrual in August 2006. Data from the 20 patients enrolled in the first stage are presented here. Results: Patients (60% male) had a median age of 63 and had a good performance status (85% had PS of 0). M1c disease was present in 45% of patients and 35% had undergone previous chemotherapy for stage IV melanoma (50% prior immunotherapy). Only 6 patients did not complete more than 2 cycles of chemotherapy due to refusal (3), desire for alternative treatment (1) or progression (2). Median follow-up among the 15 patients still alive was 5.5 months (range: 6 weeks - 9 months). The 8-week PFS rate was 70% (14/20). The median time to progression was 163 days. One partial response was observed. There were 3 disease-related deaths at 65, 120 and 190 days post-registration. The most common toxicities were neutropenia (95%; 45% = grade 3), anemia (95%; 15% = grade 3), fatigue (90%; 5% = grade 3), leukopenia (85%; 25% = grade 3), and thrombocytopenia (75%; 5% = grade 3). Conclusions: The combination of paclitaxel, carboplatin and bevacizumab appears to be well tolerated and clinically active in patients with stage IV melanoma.

8524 Background: Metastatic melanoma lacks effective therapy. Pazopanib is a small-molecule inhibitor of VEGFR-1,2,3, PDGFR-B and c-KIT that has antiangiogenic activity in renal cell cancer as well as inhibition of melanoma tumor xenografts. We designed a phase II single arm, open label clinical trial evaluating pazopanib in combination with metronomic paclitaxel as first line therapy for subjects with unresectable stage III and stage IV melanoma. Methods: This protocol utilizes a Simon 2-stage Minimax design, with a planned interim analysis to confirm >3 responders to move to the second stage. To date, 20 eligible patients have been enrolled with 17 evaluable for response. All subjects were treatment naïve and received paclitaxel at 80mg/m2 weekly for three weeks in a 4 week cycle and pazopanib at 800mg as a continuous daily oral dose. The primary endpoint is 6 month progression free survival. Exploratory endpoints include biomarker analysis that may be associated with treatment outcomes (serum VEGF, soluble VEGF R2, serum HIF, serum TSP1 and BRAF mutation status). An additional exploratory endpoint includes the in vitro activity of pazopanib and paclitaxel on patient biopsy material co-cultured with vascular endothelial cells. RECIST criteria were used to define treatment response. Results: For the 17 evaluable patients treated to date the following results were seen: 1 CR, 6 PR’s, 8 SD’s and 2 PD’s. The overall RR (CR+PR) was 40%. Total disease control rate was 80% (PR+SD). The most common AEs/lab abnormalities were nausea (71%), hypertension (57%), fatigue (57%) and vomiting (43%). Grade 3-4 AEs included hypertension (28%), transaminitis (21%) and neutropenia (14%). One patient discontinued for grade 4 transaminitis which subsequently resolved completely. Dose reductions were required for pazopanib in 5 patients and for paclitaxel in one patient. Conclusions: Planned interim analysis of this phase II study demonstrated that pazopanib in combination with paclitaxel was well tolerated and resulted in a 40% response rate, indicating that this combination is of further interest. Accrual will continue to reach a goal of 60 patients.
