NCT02082522
Photodynamic therapy (PDT) is a combination of a drug, porfimer sodium (Photofrin), which is activated by a light from a laser that emits no heat. This technique works to allow the medical doctor to specifically target and destroy abnormal or cancer cells while limiting damage to surrounding healthy tissue. The activation of the drug is done by lighting the abnormal areas using a fiber optic device (very fine fiber like a fishing line that permits light transmission) inserted into a flexible tube with a light called cholangioscope for the bile duct. The light will activate the porfimer sodium concentrated in the abnormal tissue, leading to its destruction. This research study will evaluate the efficacy and safety of PDT with porfimer sodium administered with Standard Medical Care (SMC) compared to SMC alone on the overall survival time of patients with non-operable advanced cholangiocarcinoma, a rare cancer of the bile ducts. It will involve 200 patients across North America and Europe. Other countries may participate if needed. Participation will last at least 18 months.
NCT02165449
The drug Ketamine, available in medical practice since the late 1960s, is currently used for inducing general anesthesia or sedation during medical procedures. When given slowly as an injection into a vein, ketamine is shown to produce a very rapid effect on depression and to improve depressive symptoms within hours to days. By studying patients who receive a ketamine IV infusion, as an add-on treatment for depression, investigators may start to understand how changes in the brain or in gene function relate to getting better over a very short period of time. In this study, the investigators will enroll 60 patients currently ill with major depression selected to receive IV ketamine therapy under medical supervision. To study neurobiological changes relating to symptom improvement, the investigators will use advanced brain scans to measure brain structure, chemistry and function. Blood samples will measure changes in gene regulation and immune system response. Although some people have a rapid antidepressant response to ketamine, others do not respond. Also, antidepressant effects after ketamine usually wear off within days to weeks. We will determine if up to four doses of ketamine delivered two to three times a week may prolong antidepressant response to ketamine therapy. To determine the durability of ketamine treatment for depression, patients will be monitored by phone and via electronic devices twice a week for up to five weeks and will return for a final assessment when their symptoms return. For this trial, brain and blood sample measurements will occur before and after a patient receives their first ketamine infusion. Patients who do not remit after an initial dose of ketamine, will receive up to three additional ketamine treatments. Mood will be measured 24-hours after each subsequent ketamine infusion and brain and blood measurements be repeated at the time of remission or after the fourth ketamine infusion if remission does not occur. Patients will return for a final brain scan and blood sample when their depressive symptoms return or at five weeks if they continue remission. Investigators will able to see how changes brain measurements, gene regulation and immune response relate to improvements and relapse of depressive symptoms with ketamine IV therapy. The ketamine infusion sessions will occur at a special research unit (CTRC) at UCLA.
NCT00365794
A. HYPOTHESES: In older men low testosterone levels, abdominal obesity and elevated fasting insulin who are at risk for the cardiovascular complications such as heart attack and stroke. 1. Supplemental testosterone will decrease abdominal adipose tissue and hepatic fat) and appendicular fat and intramyocellular lipid in peripheral muscles (IMCL). 2. Supplemental testosterone will improve insulin sensitivity by: 1. Decreasing hepatic glucose output (HGO), a measure of central insulin resistance 2. increasing peipheral glucose disposal (Rd), a measure of periperal insuln sensiivity 3. . Improving peripheral glucose disposal (Rd) by reducing IMCL 4. Increasing appendicular skeletal muscle mass B. OBJECTIVES: 1. Primary Objective: To determine the effects of supplemental testosterone to achieve testosterone levels in the upper normal physiologic range on central adipose tissue (abdominal and hepatic fat) and peripheral skeletal muscle fat (appendicular fat and IMCL). 2. Secondary Objectives: To determine the effects of supplemental testosterone to achieve testosterone levels in the upper normal physiologic range:on central insulin sensitivity ( hepatic glucose output (\[HGO\]) and peripheral insulin sensitivity (glucose disposal (Rd) Results of this study will provide greater understanding whether androgen therapy enhances insulin sensitivity by decreasing HGO, improving peripheral Rd and if these desired effects are achieved, whether they are due to reductions in abdominal fat or liver lipid, IMCL or effects of augmenting muscle mass per se. Results will generate hypotheses to investigate cellular and molecular mechanisms of androgen effects in persons at risk for the Metabolic Syndrome.
NCT03514927
This phase II trial studies how well high-intensity focused ultrasound works in treating participants with intermediate and high-risk prostate cancer. High-intensity focused ultrasound uses high frequency sound waves to deliver a strong beam which may target and destroy a specific part of the prostate, while minimizing damage to surrounding structures and tissue.
NCT02287922
The primary objective of this study is: \- To assess the efficacy and safety of dose regimens of ALX-0061 monotherapy administered subcutaneously (s.c.) to subjects with active rheumatoid arthritis (RA). The secondary objectives of this study are: * To assess the effects of ALX-0061 on quality of life, the pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of ALX-0061 and to explore potential dose regimens for ALX-0061 monotherapy, based on safety and efficacy, for further clinical development. * To obtain parallel descriptive information concerning the efficacy and safety of tocilizumab (TCZ) s.c. in the same clinical trial RA population.

NCT02479386
This study seeks to better characterize relationships between visual function and the progression (worsening) of geographic atrophy (GA) due to age-related macular degeneration (AMD). The study is also intended to generate new information on the relationship between genetics and GA progression. This is a global, prospective, multicenter, epidemiologic study enrolling participants with GA secondary to AMD. The study visits are scheduled to occur every 6 months. The anticipated duration of the study is up to 48 months. There is a planned interim analysis around the 2-year time window for the study.

NCT02582827
The primary objective of study CA601.2 is to determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of ABI-011 when administered by intravenous (IV) infusion on Days 1, 8, and 15, followed by a week of rest, in patients with advanced solid tumor malignancies or lymphomas. The MTD will be determined using a standard 3+3 design. The secondary objectives are to evaluate the safety and toxicity profile, to evaluate the plasma pharmacokinetics (PK), to assess the biological activity and pharmacodynamics, and to make a preliminary assessment of tumor response in patients with advanced solid tumors or lymphomas. The exploratory objectives are to determine the genomic and proteomic profile of patients' tumors to identify gene mutations, gene amplifications, levels of protein expression, and pinpoint oncoproteins. Correlations between genomic/proteomic profiles and efficacy outcomes will be assessed and principal metabolites of ABI-011 will be determined, if possible. Approximately 45-60 patients will be treated to determine dose limiting toxicities (DLTs), the MTD, and/or RP2D of ABI-011. Once the RP2D is identified, expansion of this cohort (up to 10 patients) will occur.
