Active clinical trials for "Sarcoma"

To evaluate the safety and toxicity of combination therapy for AIDS-associated Kaposi's sarcoma with zidovudine (AZT) and two kinds of interferon alpha. The two kinds are interferon alpha (IFN-A) and interferon alpha-2A (recombinant) (IFN-A2A). To define the pharmacokinetics of AZT and IFN-A or AZT and IFN-A2A when given in combination. To define the maximum tolerated dose (MTD) of each drug in combination and to define doses to be used in Phase II trial. AZT has been found to be effective against the effects of HIV in vitro (test tube) and both interferons have shown antiviral and antitumor effect on Kaposi's sarcoma. It is reasonable to assume that a synergism and an enhanced antitumor response may be seen with combination therapy. A study to evaluate the safety and effectiveness of AZT in the combination with IFN-A2A is warranted.

Primary: To evaluate the safety, toxicity, and antitumor activity of two doses of interferon alfa-2b (IFN-alpha) combined with a fixed dose of didanosine (ddI) in patients with Kaposi's sarcoma associated with HIV infection. Secondary: To evaluate the effects of combined IFN-alpha and ddI treatment on HIV expression and markers of immune function. Previous studies have shown that IFN-alpha can induce regression of Kaposi's sarcoma and suppression of HIV in some patients. Although various trials using IFN-alpha in combination with the nucleoside analogue zidovudine have demonstrated a high degree of antitumor activity and evidence of HIV suppression, the overlapping toxicity (primarily neutropenia) of these two agents has proven dose-limiting. The toxicity profile of ddI suggests that this drug may be better tolerated than zidovudine when combined with IFN-alpha.

To determine the safety and tolerance of interleukin-4 (IL-4) in patients with AIDS-related Kaposi's sarcoma. To determine the effects of IL-4 on tumor growth in patients with AIDS-related Kaposi's sarcoma. IL-4 exhibits a variety of beneficial effects on the immune system and is a potent inhibitor of Kaposi's sarcoma cells in vitro.

To define the toxicity and maximum-tolerated dose of weekly oral etoposide (VP-16) in patients with AIDS-related Kaposi's sarcoma; to determine the clinical pharmacology of orally administered VP-16 in AIDS patients. A secondary objective is to obtain preliminary data for determining the effect of oral VP-16 on Kaposi's sarcoma. VP-16 is an antitumor agent. Previous problems with VP-16 include the route of administration and the toxicities. VP-16 has been given intravenously for 3 consecutive days in a 21-day cycle for lung cancer and testicular cancer. VP-16 has also been used in lymphoma therapy. Oral VP-16 would eliminate the need for an intravenous catheter and so a patient could avoid the pain, inconvenience, and potential complications associated with medications administered intravenously. The relative ease of outpatient administration and the potentially significant antitumor activity of oral VP-16 motivates this study. The possibility of weekly drug administration is the other focus of this study.

To determine the highest tolerated dose of the safety and tolerance of interferon beta (IFN-B) when it is given at the same time as zidovudine (AZT) to patients with early AIDS related Kaposi's sarcoma. In addition, the studies will determine preliminary data on response, immune function, and subcutaneous absorption. IFN-B has demonstrated a dose-dependent ability to suppress the replication of HIV in the test tube. In addition, previous studies have shown AZT to be an effective inhibitor of HIV reverse transcriptase; Phase I and II study benefits of AZT treatment include increased objective clinical improvement, decreased mortality rate, and decreased incidence of opportunistic infections. Long-term AZT use, however, presents possible limitations secondary to intolerance. This study, therefore, will investigate the potential antiviral activities of a combination of IFN-B and AZT to determine the safety and efficacy of such treatment in patients with AIDS related Kaposi's sarcoma. It is believed that combination drug therapy consisting of low doses of each drug will reduce the potential of toxicity, treatment failures, and disease recurrences resulting from drug-resistant virus mutants.

This is a study evaluating the safety and efficacy of Lattice SBRT for patients with large tumors (≥ 4.5 cm) planning to undergo palliative radiotherapy.

This research study is designed to study the combination of two drugs, palbociclib and ganitumab, as a potential treatment for Ewing sarcoma. The names of the study drugs involved in this study are: Palbociclib Ganitumab

The Registry For Children, Adolescents And Adults With Osteosarcoma And Biologically Related Bone Sarcomas (COSS-Registry) is a non-interventional, multicentric, international, clinical and epidemiologic patient registry. The COSS-Registry collects key data on osteosarcomas or biologically related bone sarcomas. With that data collection we want to gain new scientific insights and results about this tumor disease, prognosis, surveillance and long-term effects. Besides the data collection we would also like to foster the collection of biomaterial (tumor specimen and blood samples) for scientific research. The stored material will be used to perform cell and molecular biological analyses to identify the causes of osteosarcoma, the prognosis and possible new treatment options. As a starting point the donated biomaterial of registered patients will be analyzed firstly for the presence of a tumor predisposition by germline mutations. In case of detected genetic variations that are related to the tumor disease and which may affect the patient's health and follow-up care (because of the potentially increased risk of developing other malignant tumors), affected patients will be informed and referred to genetic counseling. Registry patients will be asked at the time of diagnosis if they wish to be informed about germline variants detected as part of the study procedures.

Indo-cyanine green (ICG) is a dye that has been used for a variety of adult and paediatric uses since 1956. Over the past few years, near infrared (NIRF) technology has been developed which allow is use as a fluorescence agent during surgery. It has been used increasingly in the field of adult oncology surgery and has been shown to increase the efficacy of this surgery. The aim of this study is to evaluate the use of NIRF and ICG during specific minimally invasive surgery (MIS) procedures within paediatric oncology surgery. Their use will complement existing surgical techniques rather than replace them. Given the published advantages in adults this study aims to provide evidence of feasibility in the paediatric patients with cancer.

Pazopanib is an angiogenesis inhibitor targeting VEGFR-1, -2, and -3; PDGFR-α and -β; and the receptor c-Kit, and is indicated for the treatment of subjects with advanced renal cell carcinoma (RCC) and advanced STS. For this orphan tumor, STS, PD-L1 targeting may be a promising strategy and favorable toxicity may warrant further combination.
