Adrenergic processes stimulated by epinephrine and norepinephrine drive to the development of tumor growth and metastasis. Beta-adrenergic receptor (BAR) antagonists have shown efficacy against melanoma, breast cancer and prostate cancer. The non-specific BAR inhibitor propranolol has been used as the gold standard treatment in pediatric patients with benign infantile hemangioma which express high levels of beta adrenergic receptors potentially explaining their sensitively to propranolol. BAR have been shown to be expressed across a diverse panel of vascular tumors, with the highest expression in malignant vascular tumors including angiosarcoma. Several reports indicate positive results from beta-blockade in patients with moderately threatening vascular tumors. It remains to be determined if more malignant vascular tumor such as the angiosarcomas are susceptible to propranolol. Besides, due to the lack of adequate therapies for angiosarcoma (doxorubicin or paclitaxel and finally cyclophosphamide in third line) and to the poor prognosis of this rare and aggressive tumor, there is a strong need for the development of treatments against this tumor type. Recently using a panel of angiosarcoma cell lines. demonstrate that beta-adrenergic inhibition blocks cell proliferation and induces apoptosis in a dose dependent manner. Moreover, using in vivo tumor models they demonstrate that propanolol shows remarkable efficacy in reducing the growth of angiosarcoma tumors. Based on these proofs of mechanisms in vitro and in vivo and due to the well established safety propranolol in humans, investigators propose to determine among a wide range of propranolol dose (80 mg/d ; 120 mg/d and 160 mg/d) the optimal one based on bivariate efficacy-toxicity outcome in patients with angiosarcoma treated by cyclophosphamide. Because these two drugs have different pharmacological mechanisms, the aim is to determine the optimal dose of propranolol having the best systemic cardiovascular tolerability and the best potential antiangiogenic effect in addition with cyclophosphamide.
toxicity of each tested propranolol dose level in association to cyclophosphamide assessed according to NCI-CTC AE Version 4.0 [ Time Frame: 1 month ]
The toxicity of propranolol is well described on humans as well as its pharmacokinetic (Peak plasma concentrations occur about 1 to 4 hours) after oral dose and pharmacodynamics characteristics with the main target on beta-adrenergic receptor (blocking agent possessing no other autonomic nervous system activity). In this study the toxicity of each tested propranolol dose level in association to cyclophosphamide will be assessed according to NCI-CTC AE Version 4.0 at 1 month (Recording AE, Blood pressure, and electrocardiography). A dose-limiting toxicity (DLT) will be considered as any grade 3 or higher specially cardiac and hematologic but also non-hematologic toxicity that is probably or definitely related to treatment.
Non-progression rate [ Time Frame: 3 month ]
The efficacy criterion is defined as the non-progression rate at 3 months according to RECIST 1.1 guidelines and with central radiological review.
