Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Uveal melanoma is the most common primary intra-ocular malignancy in adults with an incidence of 0.6 - 0.7 per 100,000 per year.
Prognosis of metastatic uveal melanoma is poor. In retrospective analyses a median survival time after detection of metastases of 5 months (Flaherty et al, 1998) and 7 months (Kath et al, 1993) was reported. For patients receiving no treatment reported median survival was 2.0 months compared with 5.2 months for those receiving treatment for metastases (Gragoudas et al, 1991).
Up to now there is no established treatment of metastatic uveal melanoma. Some therapeutic approaches with locoregional treatment or systemic chemotherapy have been undertaken:
In case of metastatic disease which is confined to the liver in about 85% of patients with uveal melanoma surgical resection led to a median survival of 14 months (Mariani et al, 2009) or 19 months and a 5-year survival rate of 22% in a selected patient population (Adam et al, 2006).
As locoregional treatment option treatment with fotemustine via direct intra-arterial hepatic infusion was investigated and led to a median survival of 15 months (Peters et al, 2006). This was not a randomized trial, but a report on 101 consecutive treated patients. Additional debulking surgery was performed whenever feasible.
A randomized phase III trial comparing intra-arterial hepatic fotemustine administration with intravenous systemic fotemustine and overall survival as primary endpoint is still ongoing (EORTC 18021).
Thus, no systemic chemotherapy is approved for metastatic uveal melanoma. Although no specific genes have been linked to the pathogenesis of uveal melanoma, preclinical studies suggest potential benefit of inhibitors of Bcl-2, ubiquitin-proteasome, histone deactylase, mitogen-activated protein kinase and phosphatidylinositol-3-kinase-AKT pathways, and receptor tyrosine kinases.
Thus, sorafenib as inhibitor of b-Raf and Raf-1 (c-Raf or c-Raf-1), pro-angiogenic vascular endothelial growth factor receptor (VEGFR), and platelet-derived growth factor receptor (PDGFR) may potentially lead to a benefit for patients with metastatic uveal melanoma in terms of disease control and prolongation of survival.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Rationale for treatment of uveal melanoma with sorafenib Improved understanding of the molecular pathogenesis of cancers has led to a new generation of therapeutic agents that interfere with a specific pathway critical in tumor development or progression. Although no specific genes have been linked to the pathogenesis of uveal melanoma, which significantly differs from that of cutaneous melanoma, progress has been made in identifying potential targets involved in uveal melanoma apoptosis, proliferation, invasion, metastasis, and angiogenesis. Accordingly, improvement of systemic therapy of metastatic uveal melanoma could be achieved by using molecularly targeted agents that are currently in clinical use as well as agents being tested in clinical trials. Preclinical studies suggest potential benefit of inhibitors of Bcl-2, ubiquitin-proteasome, histone deactylase, mitogen-activated protein kinase and phosphatidylinositol-3-kinase-AKT pathways, and receptor tyrosine kinases. Modifiers of adhesion molecules, matrix metalloproteinase, and angiogenic factors also have demonstrated potential benefit. (Triozzi et al, 2008).
Thus, sorafenib as oral multi-kinase inhibitor that targets the Raf/MEK/ERK signaling pathway (CRAF, BRAF, V600E BRAF) in the cell and receptor tyrosine kinases (RTKs) such as VEGFR-2, VEGFR-3, and PDGFR-ß involved in tumor cell proliferation and angiogenesis may potentially lead to a benefit for patients with metastatic uveal melanoma in terms of disease control and prolongation of survival.
In a GCP-adapted register trial approved by the ethics committee in Essen 62 patients with metastatic uveal melanoma received treatment with sorafenib on a compassionate use basis. Median overall survival was 10.8 months in patients receiving 200 mg bid sorafenib and 7.1 months in patients receiving 400 mg bid (Scheulen et al, 2011). These treatment results are encouraging for further investigation of treatment with sorafenib in patients with metastatic uveal melanoma in a randomized trial, a potential benefit of this systemic treatment is anticipated.
Rationale for selection of a randomized discontinuation trial design The randomized discontinuation trial (RDT) design , first proposed in 1975 (Amery et al, 1975) aims to assess the clinical activity of a drug while minimizing the use of placebo. All patients receive study drug for an initial run-in period, followed by random assignment of potential responders to either the study drug or the placebo (Amery et al,1975; Kopec et al,1993). RDT design provides more homogeneous study treatment groups by selecting patients with a predefined response, and allows the evaluation of a drug's clinical activity with fewer patients and increased statistical power. Thus this study design is especially useful to distinguish anticancer activity of the drug and natural history of the underlying disease (Kopec et al,1993; Jain L et al, 2006; Rosner et al, 2002). As pointed out by Rosner the RDT design is a feasible phase II study design for evaluating possible activity of cytostatic anticancer agents whereas historically anticancer drug efficacy was evaluated as being cytotoxic (Rosner et al, 2002).
As laid down in section 3.2 sorafenib is an oral multi-kinase inhibitor that targets the Raf/MEK/ERK signaling pathway in the cell and receptor tyrosine kinases (RTKs) such as VEGFR-2, VEGFR-3, and PDGFR-ß involved in tumor cell proliferation and angiogenesis. The primary clinical benefit of sorafenib is expected to be disease stabilization rather than tumor shrinkage. As disease stabilization is substantially influenced by the natural disease of a disease, the RDT design was chosen in several phase II trials evaluating possible activity of sorafenib (such as Ratain et al, 2006; Eisen et al, 2006; Pacey et al, 2009) Taking into account that uveal melanoma is a rare disease with presumably unidentified prognostic factors the RDT design seems to be useful for objective evaluation of time to progression and overall survival.
The RDT design will ensure that all patients receive treatment with sorafenib for a run-in phase of 8 weeks and will receive further treatment with sorafenib if they experience response (complete response or partial response). Patients who experience tumor progression during this run-in phase will not remain in the study but may be offered alternative treatment. Patients who experience tumor stabilization (stable disease) will be randomized double-blinded to either sorafenib or placebo. Tumor response assessments will be performed every 8 weeks, in case of progression the patient will be unblinded and offered retreatment with sorafenib if he had been randomized to placebo. Thus, if the patient experiences progression, the effective maximum duration of a possible placebo application is confined to eight weeks.
Risk-benefit assessment of the treatment of patients with metastatic uveal melanoma with sorafenib Based on the rationale for treatment of patients with metastatic uveal melanoma with sorafenib and own clinical experience in a limited number of patients with metastatic uveal melanoma treated with sorafenib on a compassionate use basis (section 3.3), a potential benefit of this systemic treatment is anticipated.
Major potential side effects of the continuous oral treatment with sorafenib are hand-foot-syndrome, diarrhoea and increase in blood pressure which can effectively be reduced either by dose reduction or cessation of treatment with sorafenib in case of hand-foot-syndrome or diarrhoea or antihypertonic agents in case of increase of blood pressure.
Further on, the administration of sorafenib (oral intake) means fewer hospitalizations and thus constitutes an improvement of quality of life.
Thus, treatment with sorafenib is a potentially effective treatment of patients with metastatic uveal melanoma without serious side effects.
In case of short-term evaluation of inappropriate antitumor efficacy patients have the option for alternative treatment strategies either by intra-arterial liver perfusion with fotemustine or melphalan in case of metastatic disease confined to the liver or salvage chemotherapy. However it should be noted that these treatments do not represent established and authorized alternative treatment options. The only randomized phase III trial comparing intra-arterial hepatic fotemustine administration with intravenous systemic fotemustine with regard to overall survival as primary endpoint is still ongoing (EORTC 18021), all other experience is based on small phase II trials or individual treatments decisions as described in section 3.1. Any locoregional treatment such as surgery or intra-arterial hepatic infusion with fotemustine or mephalan requires that the patient does not suffer from disseminated metastasis of the liver or extrahepatic localisation of metastases.
Any placement of an intra-arterial catheter and to a lower extent, intravenous catheter is associated with the risks of catheter thrombosis, dislocation, catheter stenosis/obstruction or leakage.
The main serious side effects of melphalan and fotemustine are myelotoxicity with anemia, leucopenia and thrombocytopenia and the risk of developing acute leucemia, gastrointestinal toxicity with nausea, vomiting and diarrhoea, allergic reactions, alopecia, interstitial pneumonia, liver function disorders and renal function disorders.
Considering the poor prognosis of metastatic uveal melanoma and taking into account the lack of an established treatment to treat metastatic uveal melanoma, the risk-benefit relation of the study is assessed as positive. The possible benefit of achieving disease control with sorafenib outweighs the risk of possible side effects of sorafenib. Alternative treatment options are likewise further subject to investigation, have probably more serious side effects and certainly affect the quality of life far more as result of the intraarterial/intravenous infusional application in contrast to oral intake of sorafenib.
Thus, sorafenib as oral multi-kinase inhibitor that targets the Raf/MEK/ERK signaling pathway (CRAF, BRAF, V600E BRAF) in the cell and receptor tyrosine kinases (RTKs) such as VEGFR-2, VEGFR-3, and PDGFR-ß involved in tumor cell proliferation and angiogenesis may potentially lead to a benefit for patients with metastatic uveal melanoma in terms of disease control and prolongation of survival.
