NCT01224106
This multi-center, randomized, double-blind, placebo-controlled parallel-group study will evaluate the effect of gantenerumab (RO4909832) on cognition and functioning and the safety and pharmacokinetics in participants with prodromal Alzheimer's Disease. Participants will be randomized to receive subcutaneous (SC) injections of either gantenerumab or placebo. Participants who consent to be part of the sub study will undergo positron emission tomography (PET) scanning to assess brain amyloid. The anticipated time on study treatment is 104 weeks in Part 1, with an option for an additional up to 2 years of treatment in Part 2, followed by an open-label extension (Part 3) until July 2020. The dosing for Parts 1 and 2 was stopped after a planned futility interim analysis showed a low probability of meeting the primary outcome measure with the doses studied. The study has converted to open-label to investigate higher gantenerumab doses.
NCT01109004
The study is designed as a Phase III, multicenter trial of tandem autologous transplants plus maintenance therapy versus the strategy of single autologous transplant plus consolidation therapy with lenalidomide, bortezomib and dexamethasone (RVD) followed by maintenance therapy or single autologous transplant plus maintenance therapy as part of upfront treatment of multiple myeloma (MM). Lenalidomide will be used as maintenance therapy for three years in all arms.

NCT01627314
This study is an open-label randomized, prospectively and historically controlled trial of the safety and efficacy of a single ProHema-CB unit used as part of a double CB transplant following myeloablative or reduced intensity conditioning for subjects age 15-65 years with hematologic malignancies. A maximum of 60 eligible subjects will be enrolled and treated in the trial at approximately 10 centers within the U.S.
NCT02711956
This is an open label, non-randomized, Phase 1b/2a, dose escalation and dose confirmation study of ZEN003694 in combination with enzalutamide in patients with mCRPC.
NCT01756833
The primary aim of this study is to determine if doxycycline (100 mg bid) will inhibit (by at least 40%) the increase in greatest transverse diameter of small abdominal aortic aneurysms (3.5-5.0 cm in men, 3.5-4.5 cm in women) over a 24-month period of observation in comparison to a placebo-treated control group.
NCT00988247
Subjects with perennial allergic rhinitis will be randomized to 320 mcg of beclomethasone dipropionate (BDP) using a hydrofluoroalkane (HFA) propellant or placebo as a nasal aerosol. The subjects will be followed for safety and efficacy for a period of 30 or 52 weeks. BDP HFA is a steroid which is currently FDA approved for the treatment of asthma. BDP-HFA should be safe and effective as a "dry" nasal aerosol which may be preferred by some patients.
NCT02536339
This study will examine the safety and efficacy of pertuzumab in combination with high-dose trastuzumab in adult participants with HER2-positive MBC with CNS metastases and disease progression in the brain following radiotherapy.
NCT01291004
This study is being conducted to evaluate the impact of a 28-day oral contraceptive compared to two 28-day oral contraceptive regimens containing different synthetic progestins on ovarian follicular activity and hormone levels in healthy women.
NCT03135262
This Phase Ib/II, open-label, multicenter, non-randomized, dose-escalation study will evaluate the safety, efficacy, and pharmacokinetics of obinutuzumab in combination with idasanutlin and venetoclax in participants with R/R FL and obinutuzumab or rituximab in combination with idasanutlin and venetoclax in participants with R/R DLBCL. The study will include an initial dose-escalation phase followed by an expansion phase. The dose-escalation phase is designed to determine the recommended phase II doses (RP2Ds) and regimen for idasanutlin and venetoclax in combination with obinutuzumab for FL participants and in combination with rituximab for DLBCL participants.
NCT03065244
Kawasaki disease (KD) is a self-limited illness that affects the heart blood vessels (coronary arteries) of infants and children and is now the most common cause of acquired heart disease in children. A mixture of proteins from human blood (Intravenous immunoglobulin, IVIG) is a treatment that reduces the rate of the major complication of the disease: a bulging of the wall of the coronary arteries called an aneurysm. However, 10-20% of children are resistant to this treatment and the fever returns. These children have the highest rates of aneurysm formation and thus should be treated aggressively. Unfortunately, there are no guidelines for the best secondary treatment for these resistant patients because the problem has never been adequately studied. Most physicians choose either a second infusion of IVIG or an engineered antibody called infliximab that inactivates a molecule that promotes inflammation. This trial will randomize (assign by chance like the flip of a coin) IVIG-resistant patients to receive either a second IVIG infusion or infliximab and the response to treatment will be compared to learn which treatment stops the fever the fastest. In addition, parents and caregivers will provide observations about their child's response to the different treatments.
NCT01597778
Hematopoietic cell transplants (HCT)are one treatment option for people with leukemia or lymphoma. Family members,unrelated donors or banked umbilical cordblood units with similar tissue type can be used for HCT. This study will compare the effectiveness of two new types of bone marrow transplants in people with leukemia or lymphoma: one that uses bone marrow donated from family members with only partially matched bone marrow; and, one that uses two partially matched cord blood units.
NCT01777152
This is a double-blind, randomized, multicenter, phase 3 clinical trial to compare the efficacy and safety of brentuximab vedotin in combination with CHP with the standard-of-care CHOP in patients with CD30-positive mature T-cell lymphomas.
NCT01687153
Traumatic brain injury (TBI) and post traumatic stress disorder (PTSD) are common combat related problems and may be associated with a greater risk of Alzheimer's disease (AD). The purpose of this study is to examine the possible connections between TBI and PTSD, and the signs and symptoms of AD on Veterans as they age. The information collected will help to learn more about how these injuries may affect Veterans of the Vietnam War as they grow older, as well as Veterans of the current wars in Iraq and Afghanistan, who also have these types of combat related injuries.
NCT01472081

This is a randomized, double-blind, placebo-controlled, parallel-arm, Phase 2b adaptive dose-finding study of BLU-5937 in participants with Refractory Chronic Cough (RCC).
NCT02021773
The purpose of the study is to determine whether monthly subcutaneous administration of LBR-101 (fremanezumab) is safe and provides migraine prevention in patients with chronic migraine.
NCT01118026
This research is being done in order to improve treatment outcomes in patients diagnosed with bulky, early stage Hodgkin lymphoma and to reduce the side effects that are associated with use of radiation used in current treatments. The chemotherapy treatment in this study consists of a combination of four drugs approved by the Food and Drug Administration (FDA): doxorubicin, bleomycin, vinblastine, and dacarbazine. This regimen (called ABVD) has been found to be effective in treating patients with Hodgkin lymphoma and is considered the standard of treatment used with radiation therapy in patients with bulky early stage Hodgkin lymphoma. As part of the evaluation of the effectiveness of the chemotherapy treatment, PET scans will be obtained during the course of therapy. The usefulness of this PET scan will be evaluated to determine whether radiation may be left out in the treatment of disease if the PET scan shows that the patient has responded to chemotherapy alone. The plan is to identify a group of patients using early PET scans in order to change to a chemotherapy treatment called BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone). It is one of the most highly effective chemotherapy regimens for Hodgkin lymphoma, but is associated with more side effects than ABVD. Although it has become standard of care in Europe, its use has been more limited in the U.S. because of concerns about toxicity.
