Filter by:This phase II trial studies how well giving cixutumumab works in treating patients with metastatic melanoma of the eye. Monoclonal antibodies, such as cixutumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.
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.
Proton beam irradiation is the treatment of choice for uveal melanomas. It has favorable results in causing tumor regression while preserving the eye. Optic neuropathy has emerged consistently as an irreversible cause of visual loss in proton beam irradiated eyes. No neuroprotective strategies are available at present. Citicoline is a choline agent precursor available as a dietary supplement. Citicoline conferred acute neuroprotection and enhanced neuroplasticity in experimental stroke models. In ophthalmology, citicoline has demonstrated a significant action in improving retinal and cortical responses in patients with optic nerve diseases (glaucoma, ischemic optic neuropathy). Citicoline also exhibits a very low toxicity profile in humans. The purpose of the study is to demonstrate whether daily oral administration of citicoline in patients treated for uveal melanomas with proton beam therapy, prevents or delays the occurrence of radiation optic neuropathy. Changes in visual acuity, Pattern ERG and visual evoked potentials are measured. The tolerability/safety of the product is also evaluated.
The purpose of this study is to determine whether GSK1120212, a MEK inhibitor, is an effective and safe treatment for cancer subjects with metastatic uveal melanoma and mutation-positive GNAQ or GNA11 metastatic melanoma.
The purpose of this study is to find out what effects, good and/or bad, the drugs everolimus and pasireotide have on the patient and on melanoma. Pasireotide is also called SOM-230. Pasireotide is an experimental drug and is not approved by the Food and Drug Administration. Everolimus is also called RAD001. Everolimus is approved for use in the U.S. for kidney cancer. Everolimus is not approved for treatment of melanomas, but early studies show that it may help some patients with melanoma.
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving temozolomide together with bevacizumab may kill more tumor cells. PURPOSE: This phase II trial is studying giving temozolomide together with bevacizumab to see how well they work in treating patients with metastatic melanoma of the eye.
This randomized phase II trial studies temozolomide to see how well it works compared to selumetinib in treating patients with melanoma of the eye that has spread to other places in the body. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether temozolomide is more effective than selumetinib in treating melanoma of the eye.
This is a Phase 2, multi-center, open-label study in patients with surgically incurable stage III or IV uveal melanoma who have not received prior immunotherapy. CP-675,206 is thought to stimulate patients' immune systems to attack their tumors. CP-675,206 has been shown to induce durable tumor responses in patients with metastatic melanoma in phase 1 and phase 2 clinical studies.
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This clinical trial is studying tumor samples in patients undergoing surgery or radiation therapy for primary melanoma of the eye.
1. Rationale Immunotherapy applying ex vivo generated and tumor antigen-loaded dendritic cells (DC) has now successfully been introduced in the clinic. A limited, but consistent, number of objective immunological and clinical responses have been observed. Most of the successful results have been observed in patients with minimal residual disease, rather than patients with advanced metastatic disease. Moreover, the investigators' preliminary results show that presence of tumor epitope specific T cells in biopsies taken from delayed type hypersensitivity (DTH) reaction sites highly correlates with prolonged progression free survival (PFS). Within uveal melanoma patients, a group with high risk of metastatic disease can be identified on basis of tumor specific genetic changes in loss of chromosome 3. At present no standard adjuvant or systemic treatment is available. Applying DC-based immunotherapy in this group of high risk patients might reduce the risk of recurrence without interference in the current treatment guidelines. 2. Objectives In this joint clinical study of Radboud University Nijmegen Medical Centre (RUNMC) and Rotterdam Eye Hospital, the investigators aim to determine the in vivo immunological response induced in high risk uveal melanoma patients vaccinated with mRNA-transfected DC. 3. Study design This study is an open label non-randomized phase II intervention study. 4. Study population The investigators' study population consists of HLA-A2 positive patients with a high risk uveal melanoma with proven expression of melanoma associated antigens tyrosinase and/or gp100. 5. Main study endpoints This is an exploratory study aiming to demonstrate proof of principle. The first study endpoints are in vivo immunological response induced in high risk uveal melanoma patients vaccinated with mRNA-transfected DC, administered i.v./i.d. and toxicity. Secondary study endpoints are progression free survival, overall survival, and toxicity.
