NCT02307734
This project proposes two aims. The first aim is to evaluate the efficacy of a family-focused intervention in promoting smoking cessation in Chinese and Vietnamese male smokers using a 2-arm cluster randomized controlled trial with assessments at baseline, 6, and 12 months targeting 360 smoker-family dyads. Half of the participants will be assigned to the proposed intervention, and the remaining half will be assigned to an attention-control condition where they will receive education on healthy eating and physical activity. The second aim is to explore mediators to identify key psychosocial and behavioral processes that underlie how the intervention affects the processes of quitting and maintaining abstinence in Chinese and Vietnamese smokers.
NCT02477800
The primary objective of the study is to evaluate the efficacy of monthly doses of aducanumab in slowing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) score as compared with placebo in participants with early AD. Secondary objectives are to assess the effect of monthly doses of aducanumab as compared with placebo on clinical progression as measured by Mini-Mental State Examination (MMSE), AD Assessment Scale-Cognitive Subscale (13 items) \[ADAS-Cog 13\], and AD Cooperative Study-Activities of Daily Living Inventory (Mild Cognitive Impairment version) \[ADCS-ADL-MCI\].

NCT02655822
This is a phase 1/1b open-label, multicenter, dose-selection study of ciforadenant, an oral small molecule targeting the adenosine-A2A receptor on T-lymphocytes and other cells of the immune system. This trial will study the safety, tolerability, and anti-tumor activity of ciforadenant as a single agent and in combination with atezolizumab, a PD-L1 inhibitor against various solid tumors. Ciforadenant blocks adenosine from binding to the A2A receptor. Adenosine suppresses the anti-tumor activity of T cells and other immune cells.
NCT02658175
An open-label study of volanesorsen (ISIS 304801) administered subcutaneously to participants with FCS.
NCT03596151
This is a multi-center study with a minimum of three sites in the United States. The study will enroll approximately 1750 female subjects and will have a study duration of approximately 9 months after enrollment of the first subject. Female subjects seen at the participating sites for any reason will be evaluated for enrollment in this study. All subjects will be managed per standard of care as applicable. Subjects who are enrolled in the study will perform self-collection of a vaginal swab to be tested by Click device, and allow the health care provider (HCP) to collect three additional vaginal swabs to be tested by recognized FDA-cleared comparator methods. Subjects will complete the study in a single visit. The primary objective is to assess the performance of the Click device for detection of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) in self-collected vaginal specimens as compared to Patient Infected Status (PIS) determined by three approved comparator assays using vaginal specimens collected by a qualified HCP in support of obtaining FDA clearance.
NCT01906255
This is an observational study of HIV-1 negative individuals who participated in demonstration projects or clinical studies and took daily Emtricitabine/Tenofovir Disoproxil Fumarate (FTC/TDF, Truvada®) for pre-exposure prophylaxis (PrEP). All individuals were enrolled and followed as described in the parent PrEP demonstration project or clinical study protocol until study completion, HIV-1 infection, discontinuation due to an adverse event, lost to follow-up, or administrative censoring. In the protocols of the parent PrEP observational or clinical studies, participants had follow-up visits on average every 3 months for evaluation of adherence, renal and bone adverse events, and HIV-1 infection status. Adherence was determined by the specific FTC/TDF drug level measurement(s) outlined in the parent protocol. Gilead had collected data from 21 global PrEP demonstration projects and clinical studies for over 7,000 Truvada for PrEP users who had at least one measurement of adherence. Data from the different contributing studies were pooled for statistical analyses by Gilead.
NCT04284033
This is a randomized trial to determine if an extended wear infusion set can be worn for up to 7 days with a hybrid closed-loop system in adult with Type 1 Diabetes
NCT03605069
A double-blind, randomized, intra-subject placebo-controlled, multicenter, multiple dose study, evaluating safety, proof of mechanism, preliminary efficacy and systemic exposure in subjects with confirmed DDEB or RDEB diagnosis with one or more pathogenic mutations in exon 73 in the COL7A1 gene.
NCT02389959
This is a randomized, controlled, double-blind, placebo-controlled trial of intranasal Avastin (bevacizumab) injection versus saline control for control of HHT-related epistaxis when used in conjunction with bipolar electrocautery.
NCT03783702
Given the ongoing national opioid epidemic, an increased interest has developed in optimizing opioid prescribing practices of physicians, including otolaryngologists. Endoscopic sinus surgery (ESS) is one of the most commonly performed surgeries by otolaryngologists with over 250,000 ESS's performed annually in the U.S. Multiple studies have shown that, compared to the amount patients actually consume, otolaryngologists prescribe a high quantity of opioids to patients recovering from ESS). It has been shown that these excess opioid medications contribute to prolonged use or abuse by the patient, family members, or friends. The purpose of this study is to better understand the pain management requirements of patients who undergo ESS for recurrent acute rhinosinusitis (RARS) or chronic rhinosinusitis (CRS). This prospective, randomized, multi-institutional controlled trial will aim to determine the degree to which pain following ESS can be adequately controlled by non-opioid medications. It will also determine whether post-ESS narcotic use can be avoided entirely, or at least significantly limited. Patients will be randomized into two groups, each of which will receive a stepwise analgesic regimen consisting of acetaminophen and oxycodone or acetaminophen and ibuprofen. Pain will be assessed daily using visual analog scales (VAS) and the Brief Pain Inventory (BPI). The results of this study will help to develop a standardized approach to pain management in the post-ESS setting and help to elucidate the role of non-opioid pain medications. The ultimate goal would be to positively affect opioid prescribing patterns among surgeons who perform ESS in order to significantly reduce the quantity of opioids prescribed to patients while continuing to adequately manage patients' pain.
NCT02471716

NCT02016885
The purpose of this study is to evaluate the safety and efficacy of glycopyrrolate compared to vehicle for the treatment of axillary hyperhidrosis.
NCT04604145
This is a study that will attempt to validate the process for detecting SARS-CoV-2 (COVID19) on a non-FDA-approved technology using self-collected saliva as the specimen. Investigators will compare self-collected saliva samples and healthcare-worker collected nasopharyngeal samples (Nasal swabs) to see if the self-collected saliva samples are similar in terms of diagnostic accuracy. Investigators will be performing this testing at the site where patients regularly go for COVID19 testing. There will be minimal risk of harm as consenting patients will only have to provide a small amount of saliva into a tube.
NCT04150523
This is a prospective, multi-center observational survey study to uncover how antibiotic differences can influence utilization decisions. The purpose is to assess the trade-offs between drug side effects and infection prevention that patients are willing to make when taking prophylactic antibiotics. Misuse of antibiotics or non-adherence to prescribed regimens is a public health issue that may be due to a variety of reasons including unclear instructions, symptom improvement and adverse events Subjects will be healthcare providers (physician or nurse) and individuals 18+ years of age in the dermatologic surgery waiting area (including patients and accompanying individuals). Participants will complete a conjoint.ly survey and choose between treatment (antibiotic vs no antibiotic) scenarios.
