| NCT00001228 ↗ | Interferon and Octreotide to Treat Zollinger-Ellison Syndrome and Advanced Non-B Islet Cell Cancer | Completed | National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) | Phase 2 | 1988-10-25 | This study will examine the safety and effectiveness of interferon-a and octreotide for the treatment of Zollinger-Ellison syndrome (gastrinoma) and advanced non-B islet cell cancer. Gastrinoma is a tumor produced by the pancreas that secretes the hormone gastrin, which in turn stimulates production of gastric juices that cause ulcers. Some of these tumors are malignant. Gastrinomas that have spread and cannot be surgically removed require drug treatment (chemotherapy). Current drug regimens, however, provide only temporary benefit and, in some cases, produce life-threatening side effects. In studies of patients with tumors similar to gastrinoma, the drugs octreotide and interferon-a, alone or in combination, showed some effect in stopping tumor growth and were better tolerated than chemotherapy. At least one-third of patients responded to treatment with either drug for at least 6 months; the two drugs given together may produce a better response than either one alone. Patients currently enrolled in an NIH study of Zollinger-Ellison syndrome whose gastrinoma has spread from the original site and cannot be surgically removed may be eligible for this study. Participants will be admitted to the NIH Clinical Center for blood and urine tests, electrocardiogram (EKG), chest X-ray and imaging studies (CT, ultrasound, MRI, octreoscan, and bone scan) before beginning treatment to evaluate the size and extent of tumors. Patients will then start interferon-a or octreotide, or both, given as injections under the skin. Treatment will continue for at least 6 months, unless side effects require stopping the drugs early. Patients whose tumors shrink or remain stable may continue treatment indefinitely. Those who do not respond to treatment will be taken off the study and offered standard chemotherapy. Patients will be admitted to the hospital for the first day or two of therapy to be monitored for side effects and to learn how to self-inject the drugs to continue therapy at home. Both drugs are given [Note: how often? once a day, twice a day, weekly?] (Octreotide is also available in long-acting form, and patients who prefer may be given this drug once a month by the doctor.) During the treatment period, patients will be seen by their personal physician every 2 weeks for the first month and once a month thereafter for a medical evaluation and check of adverse side effects of treatment. In addition, they will be admitted to the NIH Clinical Center once every 3 months for a medical evaluation and imaging studies, including CT, MRI, ultrasound, bone scan, and octreoscan, to assess the effect of treatment on tumor size. |
| NCT00001849 ↗ | New Imaging Techniques in the Evaluation of Patients With Ectopic Cushing Syndrome | Completed | Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) | Phase 2 | 1999-05-20 | Cushing Syndrome is an endocrine disorder causing an over production of the hormone cortisol. Cortisol is produced in the adrenal gland as a response to the production of corticotropin (ACTH) in the pituitary gland. Between 10% and 20% of patients with hypercortisolism (Cushing Syndrome) have ectopic production of the hormone ACTH. Meaning, the hormone is not being released from the normal site, the pituitary gland. In many cases the ectopic ACTH is being produced by a tumor of the lung, thymus, or pancreas. However, in approximately 50% of these patients the source of the ACTH cannot be found even with the use of extensive imaging studies such as computed tomography (CT) scans, magnetic resonance imaging (MRI), and nuclear scans (111-indium pentetreotide). The ability of these tests to locate the source of the hormone production is dependent on the changes of anatomy and / or the dose and adequate uptake of the radioactive agent. The inability to detect the source of ectopic ACTH production often results in unnecessary pituitary surgery or irradiation. Unlike the previously described tests, positron emission tomography (PET scan) has the ability to detect pathologic tissue based on physiologic and biochemical processes within the abnormal tissue. This study will test whether fluorine-18-fluorodeoxyglucose (FDG), fluorine-18-dihydroxyphenylalanine (F-DOPA) or use of a higher dose of 111-indium pentetreotide can be used to successfully localize the source of ectopic ACTH production. |
| NCT00084461 ↗ | Romidepsin in Treating Patients With Locally Advanced or Metastatic Neuroendocrine Tumors | Terminated | National Cancer Institute (NCI) | Phase 2 | 2004-03-01 | Phase II trial to study the effectiveness of romidepsin in treating patients who have locally advanced or metastatic neuroendocrine tumors. Drugs used in chemotherapy, such as romidepsin, work in different ways to stop tumor cells from dividing so they stop growing or die. |
| NCT00495846 ↗ | GH, IGF-I and Somatostatin Analogues in Hepatocellular Carcinoma | Completed | Azienda Ospedaliera "D Cotugno" Hospital of Infectious Diseases | Phase 2/Phase 3 | 2007-04-01 | The hepatocellular carcinoma (HCC) represents more than 5% of all human malignancies, with more than 500,000 deaths per year (1). In Campania region, mortality for HCC is 2 times higher than in the rest of Italy because of a higher locally prevalence of hepatitis-C virus infection. Development of HCC in liver cirrhosis is associated with increased DNA synthesis and regeneration of hepatocytes (2). Hepatocyte growth factor, the transforming growth factor-α, the fibroblast growth factor are well studied (3,4) while the insulin-like growth factor system (IGF-I, IGF-II and their binding proteins) has been less investigated. IGF-I and IGF-II modulate growth, metabolism and cell differentiation and have specific receptors in the liver (5). IGF-I levels in the upper normal range have been associated with an increased risk to develop prostate cancer (6), breast cancer (7) and colon cancer (8). Some data report increased expression of IGF-II in HCC (9,10) and others suggest a role of increased IGF-I bioavailability in HCC (11). We reported increased IGF-I/IGFBP-3 ratio in patients with HCC compared with those with cirrhosis with a similar liver function, so suggesting increased IGF-I bioavailability in HCC (12). There is no currently medical treatment for patients with advanced HCC which has a very poor prognosis (survival <6 months). Because of limited liver function, classical chemotherapy cannot be applied (13). In patients with HCC without cirrhosis, surgery is possible only in 5% while in those with cirrhosis first-line treatment is still questioned as survival is <50% three years after operation. Patients suitable for local resection of HCC are only those with Child-Pugh's "hyper A" liver function class, who are a minority (14-16). Percutaneous resection treatments may treat approximately 70%-90% of tumors with maximal diameters of <3 cm (15,17-19). Somatostatin analogues are indicated in patients with neuroendocrine tumors expressing somatostatin receptors type 2 and 5 and has excellent safety profile. In advanced HCC, some studies demonstrated beneficial effects (20,21) while some others did not (22,23). Only a few data are available on somatostatin receptor expression in HCC (24,25). Somatostatin analogues have also a clear-cut inhibitory effect on circulating IGF-I levels with a potential additional effect in delaying HCC progression. |
