NCT01335009
This is a global, Phase 2, open label, dose selection, proof-of-concept study to assess progression free survival in subjects with metastatic melanoma. Approximately 80 subjects at 29 sites in the U.S., U.K., Germany and Australia will be randomized into one of two dose groups: 2 mg/kg, 4 mg/kg. Weekly treatment will continue until disease progression. Subjects must have measurable disease by CT Scan or MRI and must have completed at least one prior round of chemotherapy. Subjects will be assessed for Efficacy, PK/PD, Overall survival, and Safety (Adverse Events/Adverse Events of Interest, Electrocardiograms (ECG's), clinical labs, physical exams/vital signs, tolerability).
NCT02435992
The purpose of this study is to determine whether RPC1063 is effective in the treatment of Ulcerative Colitis (UC).
NCT03261960
The objective of this study is to compare the safety and efficacy of BLI4700 bowel preparation to an FDA-approved bowel preparation as 2-day, split-dose bowel preparations prior to colonoscopy in adult patients.
NCT02685631
This research registry studies Yttrium Y 90 resin microspheres in collecting data from patients with liver cancer not capable of being removed by surgery (unresectable) for the radiation-emitting Selective Internal Radiation-Spheres (SIR-spheres) in non-resectable (RESIN) liver tumor registry. The information generated will help doctors better understand treatment patterns involving Y90 therapy, gain additional insights in the long-term outcomes for patients, as well as guide future research for using Y90 therapy, especially for those conditions where data is currently very limited or lacking.
NCT03631732
The primary objective of this study is to evaluate the efficacy of switching from a regimen of 2 nucleos(t)Ide reverse transcriptase inhibitors (NRTIs) and a third agent to a fixed dose combination (FDC) of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus continuing their baseline regimen in HIV-1 infected, virologically suppressed African American participants.
NCT02423343
The main purpose of this study is to evaluate the safety, tolerability, and efficacy of the study drug known as galunisertib in combination with nivolumab in participants with advanced refractory solid tumors and in recurrent or refractory non-small cell lung cancer (NSCLC) or hepatocellular carcinoma (HCC).
NCT03926793
This is a Phase 1B, randomized, participant- and investigator-blinded, placebo-controlled, multi-center clinical trial to evaluate the safety, pharmacokinetics (PK), pharmacodynamics (PD), and biomarkers of inhaled GB002 in adults with World Health Organization (WHO) Group 1 Pulmonary Arterial Hypertension (PAH).
NCT01346969
The study will investigate the efficacy of various doses and regimens of EXC 001 in reducing skin scarring in subjects undergoing revision of scars from prior surgery. The study will also evaluate the safety and tolerability of EXC 001 and placebo.

NCT00171730
Acromegaly is a rare, serious condition characterized by chronic hypersecretion of growth hormone (GH), generally caused by a GH-secreting pituitary adenoma. The study assessed the long-term safety and efficacy of pasireotide in participants with acromegaly.
NCT03257839
The SoftVue™ is a whole breast ultrasound system with an automated scanning curvilinear ring-array transducer that employs UST. It is currently cleared under FDA 510(k) K123209 and K142517 for use as both a B-mode ultrasonic breast imaging system and color imaging of transmission data (sound speed and attenuation). SoftVue™ is not intended to be used as a replacement for screening mammography. SoftVue uses non-ionizing ultrasound energy to generate tomographic image volumes of the whole breast. While the patient lays prone on a padded table with one breast comfortably submerged in a bath of warm water, a ring-shaped transducer, 22 cm in diameter, encircles the breast and pulses low-frequency sound waves through the water and into the breast tissue. More than 2000 elements in the curvilinear transducer's 360 degree array emit and receive ultrasound signals to analyze echoes from the breast anatomy in all directions, from the chest wall to the nipple. Not only does SoftVue capture data from the reflection of the sound waves off of tissue boundaries and structures within the breast, but because the transducer surrounds the whole breast, SoftVue also captures signals that are transmitted through the breast. This additional transmission data enhances the visualization of the anatomic structure of the breast tissue and is not currently available in any other commercially marketed breast ultrasound device. This prospective, multicenter, multi-arm, clinical case collection program is IRB-approved and will be conducted in compliance with Good Clinical Practice, the Declaration of Helsinki and all applicable regulatory requirements. Arm 1 aims to collectively enroll up to 17,500 women at a total of up to 8 clinical sites. The design of this protocol is strictly limited to case collection; all investigational and statistical plans for future analyses will be prepared and registered separately, if they are applicable to the requirements of FDAAA 801. Arm 1 is limited to the cohort of asymptomatic women, with heterogeneously or extremely dense breast parenchyma (BI-RADS breast composition category c or d). Matched triads of 2D digital mammography (FFDM), 3D digital mammography (DBT), and SoftVue automated whole breast ultrasound (SV)exams, from the same patient, with demographic information and clinical outcome data, will be collected during the same screening imaging episode. Ultrasound characteristics for all types of lesions, whether they are benign or malignant, will be collected, as well as objective and subjective breast density composition data. The exams and clinical data accumulated in this prospective case collection (PCC) protocol will populate a database from which future investigations may be designed for peer reviewed publication, development of user training curriculums, building teaching case, and creating new marketing materials for SoftVue.A subset of exams will be sampled from Arm 1 for use in ROC Reader Study (protocol DMT-2015.002), which will be separately registered and is designed to evaluate the safety and efficacy of a new screening indication for use of SoftVue™ as an adjunct to screening mammography. The results of this ROC Reader Study will be submitted to the FDA for their consideration of a PMA application for SoftVue.
