NCT00003811
RATIONALE: Chemotherapy drugs use different ways to stop tumor cells from dividing so they stop growing or die. Chemoprotective drugs such as amifostine may protect normal cells from the side effects of chemotherapy. PURPOSE: Phase I trial to study the effectiveness of high-dose cisplatin, etoposide, and bleomycin plus amifostine in treating children who have malignant germ cell tumors.
NCT00007501
The incidence and severity of HZ (or shingles), as well as the frequency and severity of its complications, increases markedly with increasing age. More than half of all cases occur in persons over the age of 60. Even without complications, HZ can interfere with an elderly patient's ability to perform essential activities of daily living, resulting in a loss of independence that is emotionally devastating and frequently irreversible. The most common complication of HZ in elderly persons is postherpetic neuralgia (PHN), which frequently results in disordered sleep, chronic fatigue, anxiety and severe depression. Antiviral therapy has a modest impact on the acute phase of HZ. However, it does not appear to prevent the development of PHN. This study is a 5.5 year randomized, double-blind, placebo-controlled, efficacy trial to determine whether vaccination with live-attenuated Oka/Merck varicella-zoster decreases the incidence and/or severity of herpes zoster (HZ) and its complications in adults 60 years of age and older.
NCT01319318
This study will evaluate the degree of post-operative ocular inflammation in patients who are undergoing a pars plana vitrectomy.
NCT00767338
The primary research hypothesis is that microsurgical varicocelectomy will result in an increase in live birth in infertile couples where the male partner has a palpable varicocele and an abnormal semen analysis in comparison to male partners who do not have microsurgical varicocelectomy. The secondary hypotheses include: 1. To assess whether up to 4 cycles of intrauterine insemination confers any additional increase in live birth rates compared to timed intercourse; 2. To examine spousal pregnancy rate as the secondary outcome; and 3. To study the effect of varicocelectomy in men with infertility, an abnormal semen analysis, and a palpable varicocele on * Testicular semen analysis parameters; * Serological measures of FSH, LH, total and free testosterone and * Measures of quality of life and sexual function in both partners.
NCT00009698
RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill more cancer cells. PURPOSE: Phase I trial to study the effectiveness of interleukin-2 in treating children who have undergone bone marrow transplantation for acute myeloid leukemia.
NCT00002596
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not known whether combining chemotherapy with bone marrow or peripheral stem cell transplantation is more effective than combination chemotherapy alone in treating men with germ cell tumors. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without bone marrow or peripheral stem cell transplantation in treating men with previously untreated germ cell tumors.
NCT00016198
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combining fluorouracil and leucovorin with or without oxaliplatin in treating patients who have recurrent metastatic colorectal cancer.
NCT00003568
RATIONALE: Vaccines may make the body build an immune response that will kill tumor cells. Interleukin-2 may stimulate a person's white blood cells to kill melanoma cells. PURPOSE: Randomized phase II trial to study the effectiveness of vaccine therapy with interleukin-2 in treating patients with metastatic melanoma.
NCT00032123
RATIONALE: Biological therapies such as erlotinib may interfere with the growth of tumor cells and slow the growth of the tumor. PURPOSE: Phase II trial to study the effectiveness of erlotinib in treating patients who have locally advanced or metastatic stomach cancer or cancer of the gastroesophageal junction.
NCT00996580
This is an open-label, single-treatment study. All subjects will receive 12 months of oral contraceptive therapy with DR-103. Study participants will receive physical and gynecological exams, including Pap smear. During the study, all participants will be required to complete a diary.
NCT00006093
RATIONALE: EMD 121974 may stop the growth of cancer by stopping blood flow to the tumor. PURPOSE: Phase I/II trial to study the effectiveness of EMD 121974 in treating patients who have progressive or recurrent malignant glioma.
NCT00023725
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as SU5416 may stop the growth of cancer by stopping blood flow to the tumor. It is not yet known if radiation therapy is more effective with or without SU5416 in treating soft tissue sarcoma. PURPOSE: Phase I/II trial to compare the effectiveness of radiation therapy with or without SU5416 in treating patients who have stage IB or stage IIA soft tissue sarcoma.
NCT01569776
The primary objective of this clinical trial is to determine whether a new amino acid-based formula is hypoallergenic as defined by the American Academy of Pediatrics (2000), demonstrating that the test formula does not provoke allergenic activity in 90% of infants or children with confirmed cow's milk allergy (CMA) with 95% confidence as compared to a commercially available hypoallergenic formula.
NCT00433394
RATIONALE: Collecting informed consent from parents of children with cancer to register with the Childhood Cancer Research Network may help the study of cancer in the future. PURPOSE: This study is collecting informed consent to register younger patients with cancer into the Childhood Cancer Research Network.
NCT00003078
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy and chemotherapy may kill more tumor cells. It is not known whether receiving radiation therapy plus cisplatin is more effective than receiving radiation therapy plus fluorouracil in treating patients with cancer of the cervix. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy plus cisplatin or fluorouracil in treating patients with primary stage IIB, stage IIIB, or stage IVA cancer of the cervix.
NCT00012324
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which chemotherapy regimen is more effective for liver cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two different chemotherapy regimens in treating patients who have recurrent or unresectable liver cancer.
NCT01272102
To determine the area under the Receiver Operator Characteristic Curve (AUC) for the Ganglion Cell Analysis (GCA) average thickness.
NCT00113399
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cisplatin and paclitaxel may make tumor cells more sensitive to radiation therapy. Giving more than one drug (combination chemotherapy) and giving them with radiation therapy may kill more tumor cells. It is not yet known whether giving radiation therapy together with combination chemotherapy is more effective than giving combination chemotherapy alone in treating head and neck cancer. PURPOSE: This randomized phase III trial is studying radiation therapy and combination chemotherapy to see how well they work compared to combination chemotherapy alone in treating patients with recurrent head and neck cancer that cannot be removed by surgery.
NCT00359944
The purpose of this study is to investigate efficacy and safety of different doses of AC-3933 in patients with mild to moderate Alzheimer's Disease.
NCT01337154
The goal of this study is to determine the progression-free survival and objective response rate in subjects with either stage IIIB with pleural effusion NSCLC or stage IV NSCLC who are treated with up to six cycles of paclitaxel plus carboplatin and either tamibarotene or placebo. Subjects will be randomly assigned to receive tamibarotene, 6 mg/m2, divided as twice daily orally, or an equal number of matching placebo tablets, starting 1 week before chemotherapy and continuing through all 6 cycles and beyond. Subjects will be assessed for response on Day 50, Day 113, then every other month using the Response Evaluation Criteria in Solid Tumors (RECIST 1.1).
