| OTC | NCT01188096 ↗ | A Trial of Poly-ICLC in the Management of Recurrent Pediatric Low Grade Gliomas | Completed | Emory University | Phase 2 | 2010-08-01 | This study is for patients up to 21 years of age who have a tumor called a low grade glioma of the central nervous system (brain and spinal cord). The tumor has grown despite attempts to control it with chemotherapy or radiation. Low grade gliomas are a group of tumors that tend to grow slowly and could be cured if every bit of the tumor were surgically removed. These tumors are called Grade I or II astrocytomas. These tumors often grow in parts of the brain that prevent total removal without devastating neurologic complications or death. Although some low grade gliomas never grow, most will and are treated with either chemotherapy or radiation. There is good data showing that the growth of most low grade gliomas can be controlled with chemotherapy or radiation. However, some low grade gliomas in children and young adults grow despite these treatments. Poly-ICLC is a new drug that has been used safely in children and adults with different types of brain tumors. Earlier studies showed that this drug worked better for children and young adults with low grade gliomas than for children with more aggressive brain tumors. The main purpose of this study is to use Poly-ICLC treatment in a larger number of patients to see how well it works and how many side effects occur. As Poly-ICLC is not FDA approved, this study is authorized to use it under IND# 43984, held by Oncovir. Subjects will get injections of Poly-ICLC into muscle two times weekly. The first treatments will be given in the clinic so allergic or other severe reactions, if any, can be monitored. If subjects tolerate the injections and don't have a severe reaction, then the rest of the injections will be given at home. Subjects/caregivers will be trained to give injections. Treatment will last for about 2 years. Subjects may stay on treatment for longer than 2 years if their tumor shrinks in response to the injections, if study doctors think it is safe, if subjects want to remain on treatment, and if Poly-ICLC is available. Risks: Poly-ICLC has been used safely in children and adults at the dose used in this study, and at higher doses. Frequently seen side effects include irritation of the skin at the injection site and mild flu-like symptoms. These are usually relieved or avoided by use of over-the-counter medicines like acetaminophen (Tylenol). Funding Source: FDA OOPD |

| OTC | NCT01241513 ↗ | Induced Changes in Ventilatory Responsiveness and Altitude Exposure | Terminated | United States Army Research Institute of Environmental Medicine | Phase 4 | 2010-11-01 | The main purpose of this study is to determine if a drug (acetyl-cysteine or ACCY) can increase the amount of oxygen in your body at a high altitude of 11,500 feet. ACCY is approved by the Food and Drug Administration (FDA) as a treatment or antidote for Tylenol overdoses. Other forms of ACCY are also sold over-the-counter as nutritional supplements. In this study, the FDA-approved form of ACCY will be used "off-label" (meaning in a way not approved by the FDA). This study is being conducted by researchers from the United States Army Research Institute of Environmental Medicine (USARIEM). The study will take place in the Altitude Chamber located in the basement of USARIEM. A total of approximately 30 volunteers (men and women, military and civilians) will take part in the study. They can expect to be in the study for a minimum of a few hours each day for two weeks. The investigators hypothesize that ACCY will improve ventilation and oxygenation while at altitude. |
| OTC | NCT01878695 ↗ | Pilot Study of Anti-oxidant Supplementation With N-Acetyl Cysteine in Stage 0/I Breast Cancer | Completed | Sidney Kimmel Cancer Center at Thomas Jefferson University | Phase 1 | 2012-07-26 | NAC is the N-acetyl derivative of the naturally occurring amino acid, L-cysteine. It is a common over-the-counter supplement and also is available as an injectable pharmaceutical that protects the liver in cases of acetaminophen overdose. In the exercise physiology literature, both oral and injectable NAC have been shown to reduce fatigue and improve recovery from exertion which has interesting implications for exploring cancer-related fatigue. In terms of cancer cell biology, reactive oxygen species (ROS) may play an important role in the development and progression of breast cancer |

| NCT00000925 ↗ | A Study to Evaluate High Protein Supplementation in HIV-Positive Patients With Stable Weight Loss | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 2 | 1999-05-01 | The purpose of this study is to determine whether a high-quality protein food supplement will help HIV-positive patients maintain, and possibly gain, muscle mass. Many HIV-positive patients lose weight that they are then unable to regain. This may be because patients are not eating enough protein or are not eating the right kinds of protein. The protein eaten in foods (such as meat, eggs, or beans) may not be able to make up for the amount of protein lost due to HIV infection. This study gives patients high-quality protein food supplements to help them maintain and/or gain weight. |
| NCT00004831 ↗ | Study of Cysteine Hydrochloride for Erythropoietic Protoporphyria | Completed | St. Luke's-Roosevelt Hospital Center | N/A | 1996-10-01 | OBJECTIVES: I. Determine the efficacy of cysteine hydrochloride in preventing or decreasing photosensitivity in patients with erythropoietic protoporphyria. |
| NCT00004831 ↗ | Study of Cysteine Hydrochloride for Erythropoietic Protoporphyria | Completed | FDA Office of Orphan Products Development | N/A | 1996-10-01 | OBJECTIVES: I. Determine the efficacy of cysteine hydrochloride in preventing or decreasing photosensitivity in patients with erythropoietic protoporphyria. |
| NCT00004940 ↗ | Phase III Study of L-Cysteine in Patients With Erythropoietic Protoporphyria | Completed | Brigham and Women's Hospital | Phase 3 | 1996-05-01 | OBJECTIVES: I. Determine the long-term efficacy and safety of L-cysteine in the prevention photosensitivity in patients with erythropoietic protoporphyria. |
| NCT00056433 ↗ | Evaluation of Hydroxyurea Plus L-arginine or Sildenafil to Treat Sickle Cell Anemia | Completed | National Institutes of Health Clinical Center (CC) | Phase 1 | 2003-03-10 | Patients with sickle cell disease have abnormal hemoglobin (the protein in red blood cells that carries oxygen to the body). This abnormality causes red blood cells to take on a sickle shape, producing disease symptoms. Fetal hemoglobin, a type of hemoglobin present in fetuses and babies, can prevent red cells from sickling. The drug hydroxyurea increases fetal hemoglobin production in patients with sickle cell disease by making a molecule called nitric oxide. The drugs L-arginine and Sildenafil (Viagra) increase the amount or the effect of nitric oxide. This study will evaluate: - The safety of giving L-arginine or Sildenafil together with hydroxyurea in patients with sickle cell disease; - The effectiveness of L-arginine plus hydroxyurea or Sildenafil plus hydroxyurea in increasing fetal hemoglobin in patients with sickle cell disease; and - The effectiveness of L-arginine plus hydroxyurea or Sildenafil and hydroxyurea in lowering blood pressure in the lungs of patients with sickle cell disease. (Pulmonary blood pressure is elevated in about one-third of patients with sickle cell disease, and this condition increases the risk of dying from the disease.) Patients with hemoglobin S-only, S-beta-thalassemia, or other sickle cell disease genotype may be eligible for this study. Before starting treatment, patients will have a complete medical history and physical examination. All patients will take hydroxyurea once a day every day by mouth for at least 2 months. They will be admitted to the NIH Clinical Center to take their first dose of hydroxyurea, and will have blood drawn through a catheter (plastic tube placed in a vein) every hour for 6 hours for tests to determine nitric oxide levels. After discharge, they will return to the clinic once every 2 weeks to check for treatment side effects and for blood tests to monitor hemoglobin and fetal hemoglobin levels. After fetal hemoglobin levels have been stable for 2 months, patients will be admitted to the Clinical Center for their first dose of L-arginine (for men) or Sildenafil (for women). Again, blood samples will be collected through a catheter once an hour for 6 hours. If there are no complications, patients will be discharged and will continue taking hydroxyurea once a day and L-arginine or Sildenafil three times a day for at least 3 months until fetal hemoglobin levels have been stable for at least 2 months. Patients will return to the clinic for blood tests every week for 2 weeks and then every 2 weeks to monitor hemoglobin and fetal hemoglobin levels and to check for treatment side effects. Patients will have eye examinations before and during treatment. Some patients with sickle cell disease develop abnormalities in the blood vessels of the eye. Also, Sildenafil can cause temporary changes in color vision. Rarely, more serious eye problems can occur, such as bleeding from the eye blood vessels or damage to the retina a layer of tissue that lines the back of the eye. Patients will also have an echocardiogram (ultrasound of the heart) before beginning treatment, after hydroxyurea treatment, and after 1 and 3 months of combined treatment with hydroxyurea and L-arginine or Sildenafil to help measure blood pressure in the lungs. Patients who develop complications from L-arginine or Sildenafil may continue in the study on hydroxyurea alone. Patients whose fetal hemoglobin levels increase with the combination therapy of hydroxyurea and L-arginine or Sildenafil may continue to take them. |
