Active clinical trials for "Hemangiosarcoma"

This phase III trial is studying observation to see how well a risk based treatment strategy works in patients with soft tissue sarcoma. In the study, patients are assigned to receive surgery +/- radiotherapy +/- chemotherapy depending on their risk of recurrence. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery.

This Phase 2, open-label study is designed to examine the efficacy and safety of single-agent AGEN2034 and combination AGEN2034 + AGEN1884 in patients with recurrent, inoperable or metastatic Angiosarcoma (AS).

This is an open label, two-stratum, phase 2 clinical trial evaluating the efficacy of 9-ING-41 in combination with gemcitabine/docetaxel in patients ≥10 years of age with advanced sarcoma. 9-ING-41 in combination with gemcitabine and docetaxel will lead to sustained disease control and/or increase the rates of objective response in patients with unresectable or metastatic soft tissue and bone sarcomas.

9-ING-41 in combination with gemcitabine and docetaxel will lead to sustained disease control and/or increase the rates of objective response in patients with unresectable or metastatic soft tissue and bone sarcomas. This is an open label, two-stratum, phase 2 clinical trial evaluating the efficacy of 9-ING-41 in combination with gemcitabine/docetaxel in patients ≥10 years of age with advanced sarcoma. Stratum A: Patients with advanced soft tissue sarcoma previously treated with 0-3 prior lines of systemic therapy will receive 9-ING-41 twice weekly with gemcitabine on days 1 and 8 and docetaxel on day 8 of a 21-day cycle until disease progression or unacceptable toxicity. Stratum B: Patients with relapsed or refractory bone sarcoma previously treated with at least one line of systemic therapy will receive 9-ING-41 twice weekly with gemcitabine on days 1 and 8 and docetaxel on day 8 of a 21-day cycle until disease progression or unacceptable toxicity. Disease response assessment will be performed every 2 cycles (6 weeks) for the first 8 cycles (24 weeks), then every 12 weeks thereafter.

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.

To investigate the efficacy of Avelumab when given in combination with paclitaxel as a first line treatment for the patients with inoperable angiosarcoma.

RATIONALE: Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well sorafenib works in treating patients with angiosarcoma that is locally advanced, metastatic, or unable to be removed by surgery.

This study is multicenter (up to 10 sites in India) phase IV Post-Marketing Study. The study is designed to investigate the safety of Lipiodol® Ultra Fluid in association with surgical glues used according to each site medical practice of vascular embolization. Subjects will be enrolled with the main condition that a procedure of vascular embolization using Lipiodol® Ultra Fluid in association with surgical glues is part of their therapeutic/palliative strategy for their disease. The vascular embolization using Lipiodol® Ultra Fluid in association with surgical glue will be administered as study procedure. According to the patient need and health status a second vascular embolization using Lipiodol® Ultra Fluid in association with surgical glue may be considered by the investigator within the next 30 days after the first one. In this case, this procedure will be considered as a second study procedure. The per-procedure safety evaluation will be enabled by appropriate records of safety events during the time frame of the procedure of vascular embolization using Lipiodol® Ultra Fluid in association with surgical glues. Safety evaluation will be completed with safety records within 30 +/-3 days after the embolization procedure. Efficacy evaluation will rely on the level of lesion(s) obliteration after embolization compared to the pre-procedural target level of obliteration. Exploratory descriptive statistical methods will be used to evaluate safety and efficacy, using both the total population and subsets of subjects with similar clinical conditions.

This study evaluates the accuracy of a new ultrasound technology called microvessel imaging for detecting the extent of disease among patients with angiosarcoma of the skin. Microvessel ultrasound imaging uses high frequency waves to visualize vessels in the skin that are not easily seen using other imaging tests.

Cytological diagnosis of hepatic angiosarcoma by fine-needle aspiration (FNA) or imprint cytology is difficult due not only to its various cytomorphologic features but also clinical rarity. Vasoformative features, such as pseudo-acini, branching pseudo-capillary structure, and intracytoplasmic lumina, are clues to achieve the diagnosis. But these features are not always present. In order to find clues for cytological diagnosis of angiosarcoma, we collected cases of hepatic angiosarcoma to study their cytological features. And then compared these features with those in their histopathological biopsy or resection.
