NCT00109850
RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab may also stop the growth of esophageal cancer by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cisplatin and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving cetuximab together with combination chemotherapy and radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving cetuximab together with combination chemotherapy and radiation therapy works in treating patients with locally advanced esophageal cancer that cannot be removed by surgery.
NCT00006994
RATIONALE: Glutamine may be effective in decreasing side effects, such as inflammation of the mouth and throat, caused by radiation therapy. The effectiveness of glutamine for mucositis is not yet known. PURPOSE: Randomized phase III trial to determine the effectiveness of glutamine in treating patients who develop mucositis following radiation therapy for newly diagnosed cancer of the mouth or throat.
NCT00005087
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Radiation therapy uses high-energy x-rays to damage tumor cells. PURPOSE: Phase II trial to study the effectiveness of paclitaxel, cisplatin, and filgrastim combined with radiation therapy in treating patients who have locally recurrent head and neck cancer and have received previous treatment with radiation therapy.
NCT00003417
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Computer systems that allow doctors to create a 3-dimensional picture of the tumor in order to plan treatment may result in more effective radiation therapy. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of radiation therapy that has been planned with a computer plus chemotherapy in treating patients who have glioblastoma multiforme.
NCT00003162
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known which radiation therapy regimen is more effective for bone metastases. PURPOSE: Randomized phase III trial to compare different radiation therapy regimens in treating patients who have bone metastases from breast or prostate cancer.
NCT00011999
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy with radiation therapy following surgery may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of chemotherapy plus radiation therapy in treating patients who have undergone surgery for stage III or stage IV head and neck cancer.
NCT00003139
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as pilocarpine may protect normal cells from the side effects of radiation therapy. It is not yet known if pilocarpine may be effective in preventing mucositis and dry mouth in patients receiving radiation therapy for head and neck cancer. PURPOSE: Randomized, double-blinded, phase III trial to study the effectiveness of pilocarpine in preventing mucositis and dry mouth in patients receiving radiation therapy for head and neck cancer.

NCT00057759
RATIONALE: Sildenafil may be effective in helping patients who have undergone treatment for prostate cancer to have an erection for sexual activity and may improve sexual satisfaction and quality of life. PURPOSE: Randomized clinical trial to study the effectiveness of sildenafil in treating erectile dysfunction in patients who have undergone radiation therapy and hormone therapy for prostate cancer in clinical trial RTOG-9910.
NCT00075868
RATIONALE: Octreotide may be effective in preventing or controlling diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer. It is not yet known whether octreotide is effective in treating diarrhea. PURPOSE: This randomized phase III trial is studying octreotide in preventing or reducing diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer.
NCT01437878
This is a phase 2, Multi-center, double-blind, randomized, placebo-controlled study to evaluate the effects of inhaled Iloprost in patients with pulmonary hypertension secondary to COPD. The main objective is to investigate the effect of iloprost on exercise endurance time during constant work rate cardiopulmonary exercise testing. Other efficacy and safety endpoints will additionally be analyzed.
NCT00829816

NCT02475616
This is a single-center, placebo-controlled, randomized, double-blind, dose-escalation study to evaluate safety, tolerability, and PK of a single oral (PO) administration of PCO371 in healthy adult males. Caucasian and Japanese subjects will be randomized to receive either PCO371 or placebo.
NCT01298401
RATIONALE: Monoclonal antibodies, such as ganitumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as gemcitabine hydrochloride and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Specialized radiation therapy, such as 3-dimensional conformal radiation therapy, that delivers a high-dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase I trial is studying the side effects and best dose of ganitumab when given together with gemcitabine hydrochloride followed by radiation therapy, ganitumab, capecitabine, and maintenance therapy in treating patients with locally advanced cancer of the pancreas.
NCT00475085
RATIONALE: Antiemetic drugs, such as granisetron, dexamethasone, prochlorperazine, aprepitant, and palonosetron, may help lessen or prevent nausea. It is not yet known which combination of antiemetic drugs is more effective in preventing nausea caused by chemotherapy. PURPOSE: This randomized phase III trial is comparing different combinations of granisetron, dexamethasone, prochlorperazine, aprepitant, and palonosetron to see how well they work in preventing nausea in patients undergoing chemotherapy for breast cancer.

NCT02027610
Vitamin A deficiency (VAD) increases the risk of death from infections in infants and young children. The World Health Organization (WHO) recommends high-dose vitamin A supplementation (VAS) from 6-59 months of age to reduce the risk of death in countries where VAD is common. Such countries include Bangladesh, where this study is being conducted. While providing VAS at 6 months is recommended, providing VAS at birth may also decrease the risk of death since newborn infants are also at risk of VAD. VAS presumably reduces infant mortality by improving the immune response to infection and immunization. Vitamin A particularly affects the development and function of T cells, which develop in the thymus and are a key component of the memory response to infection and immunization. Vitamin A is important for development of an important class of T cells, regulatory T-cells, in the intestine. Regulatory T-cells prevent over-reaction of the immune system to substances the immune system might otherwise treat as harmful such as food or the healthy bacteria in the intestine. VAD could disrupt the normal colonization of the infant's intestinal tract and cause a condition called "dysbiosis" where abnormal bacteria flourish and adversely affect the infant's immune system. Dysbiosis may disrupt the immune response to injectable and oral vaccines. VAS at birth may prevent dysbiosis and thus improve immune function, response to vaccines, and child survival. The investigators recently completed an intervention trial in Bangladeshi infants (NCT01583972) examining the effect of VAS at birth on immune function and response to vaccines administered from birth to 14 wk of age. The present study will recruit infants who completed NCT01583972 when they are from 12 to 24 m of age to determine if VAS at birth affects the responses to these same vaccines when they are measured during the second year of life. The investigators will examine the effect of VAS at birth on gut microbiota measured early in infancy and during the second year of life, and explore the association of the gut microbiota with vaccine response. Mothers of study infants will participate in the study because the breast milk oligosaccharide content strongly affects gut microbiota composition and the "secretor status" of the mother, which can be determined from maternal FUT2 genotype, strongly affects breast milk oligosaccharide content.
