NCT03507777
The objective of this prospective, single-blind clinical investigation is to demonstrate the superiority of an Optical Coherence Tomography (OCT)-guided stent implantation strategy as compared to an angiography-guided stent implantation strategy in achieving larger post-PCI lumen dimensions and improving clinical cardiovascular outcomes in patients with high-risk clinical characteristics and/or with high-risk angiographic lesions.
NCT04690504
Current methods for assessing circadian timing require sampling over hours (or even up to a day) while the patient is in controlled conditions. The investigators aim to develop a method that can estimate individual circadian time with a single blood sample taken at any time of the day or night. To do this, the investigators will use two state of the art methods, a plasma proteomics-based method to identify a panel of rhythmic proteins (extending our preliminary data) and a whole blood-derived monocyte-based method using a panel of 15 transcripts (to validate and extend a recent study). We will test both methods in a series of patients with circadian rhythm sleep disorders. We will validate separately the proteomics-based biomarker and the monocyte-based transcript biomarker, and also explore whether combining them can improve the accuracy of our timing estimates. In all cases, circadian phase estimates from the biomarker panels will be compared with those derived from plasma or saliva melatonin (the current "gold-standard" circadian phase marker).

This study aims to: 1. Establish the feasibility of a health-coached (HC) walking program utilizing motivational interviewing (MI) and wireless pedometers in family caregivers of persons with dementia. 2. Examine preliminary outcomes of a HC walking program utilizing MI with wireless pedometers on family caregiver's perception of wellbeing, stress, and activity level. 3. Explore caregivers' acceptability and experience of participating in a HC walking program utilizing MI with wireless pedometers and to explore additional person centered approaches.
NCT03451162
This first-in-human, Phase 1, open-label, multicenter, dose-escalation study will evaluate the safety, tolerability, and PK of DHES0815A as a single agent in participants with advanced and/or metastatic HER2-positive breast cancer for whom established treatment has proven ineffective or intolerable or is unavailable. The study may include a dose-expansion cohort (based on an ongoing assessment of the totality of data obtained in this study) to further assess safety, tolerability, PK, and preliminary anti-tumor activity.
NCT03786224
This study is a critically important first-of-its-kind investigation of the potential research utility of using contingency management to examine long-term changes in cannabis use with six months of abstinence. These pilot data will inform a later trial which will focus on testing the longitudinal relationships between adolescent cognition and cannabis use, questions of high and growing public health significance given adolescents' increased access to cannabis with legalization.
NCT01183949
The purpose of this study is to determine whether AT7519M alone or AT7519M plus bortezomib are effective treatments in patients with previously treated multiple myeloma.
NCT04852822
This study evaluates the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). CLL and SLL are types of blood cancer that begin in cells of the immune system. CLL/SLL and the medications used to treat these conditions may change the way vaccines work in a patient's body. The purpose of this study is to find out if patients with CLL/SLL make antibodies, or have an immune response, to the SARS-CoV-2 vaccines. Information gained from this study may help researchers better understand how effective the vaccines work in preventing COVID-19 (coronavirus disease 2019) in patients with CLL and SLL.
NCT02803125
The purpose of this project is to develop an intervention to improve psychosocial functioning and quality of life for older Veterans with partial or full PTSD.
NCT04634604
This randomized clinical trial will compare retinal outcomes with low-dose intravitreous bevacizumab (0.063 mg) versus laser photocoagulation as treatment for infants with type 1 retinopathy of prematurity (ROP). The study also will assess neurodevelopment, refractive error, visual acuity, and peripheral visual fields.
NCT01296555
This is an open-label, multicenter, Phase I/II study to assess the safety, tolerability, and pharmacokinetics of GDC-0032. The Phase I portion will be divided into two stages. During Stage 1, GDC-0032 will be administered every day orally and at escalating doses in participants with locally advanced or metastatic solid tumors. During Stage 2, GDC-0032 will be administered alone or as combination therapy within indication-specific cohorts. In Phase II of the study, the efficacy and safety of the combination GDC-0032 and fulvestrant will be evaluated in post-menopausal female participants with locally advanced or metastatic human epidermal growth factor receptor 2 (HER2)-negative, hormone receptor-positive breast cancer.
NCT01952782
The investigators are seeking healthy volunteers and volunteers with reproductive disorders for the study of the role of dynorphin in the reproductive system. Dynorphin is a naturally occurring opioid hormone that is blocked by naloxone. We hypothesize that naloxone, by blocking dynorphin, will stimulate production of gonadotropin-releasing hormone (GnRH) and kisspeptin, two other naturally occurring reproductive hormones.
NCT05376319
The purpose of this study is to evaluate the efficacy and safety of obinutuzumab for the treatment of proteinase 3 Anti-Neutrophil Cytoplasmic Antibody (ANCA)-Associated Vasculitis (PR3-AAV).
NCT01422148
. New- onset postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery and its occurrence increases with age. POAF can result in clinically significant morbidity and mortality. The national trend in the US is that the population older than 65 years is increasing, making healthcare expenditure related to POAF to be a major burden on health care system. Effective treatment of POAF is imperative in ensuring quality of care and reduction of costs. In 2021 there is a projected total of 377,763 cardiovascular surgeries in the US alone with approximately half of which will have POAF with longer postoperative length of stay (+3.9 days) and higher discharge costs (+$13,993) than no-POAF patients (Reference: Ann Thorac Surg. 2015 Jan;99(1):109-14). Amiodarone, the currently used therapy, is often insufficient to prevent POAF and has multiple side-effects. In this study, we expect to improve the incidence of POAF by using a common acne drug (Minocycline) that is safe and that could be incorporated in clinical care of this disease.
NCT05579977
The purpose of this study is to find out if PF-07081532 ("the active study drug"), is safe and helps treat people with obesity without diabetes to lose weight, and people with diabetes to keep their blood sugar in good control. Individuals diagnosed with diabetes that are on metformin or individuals with obesity without diabetes will be included in the study. Those participating in the diabetes part of the study, will receive either active study drug, placebo, or an approved treatment called Rybelsus. Those in the obesity part of the study, will receive either active study drug or placebo. The study will last for about 36 weeks except for the first 25% of the participants that enter in which case the study will last for approximately 48 weeks. during this time there will be visits every 4 weeks with phone calls in between.
NCT01712217

NCT02443324
The main purpose of this study is to evaluate the safety and preliminary efficacy of the combination of the study drug known as ramucirumab plus pembrolizumab in participants with locally advanced and unresectable or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma, non-small cell lung cancer (NSCLC), transitional cell carcinoma of the urothelium, or biliary tract cancer (BTC).
NCT04152863
This is a Phase 2 study to assess the efficacy, safety, and tolerability of gebasaxturev administered both intratumorally (ITu) and intravenously (IV) as combination therapy with pembrolizumab (MK-3475) versus pembrolizumab alone in anti-programmed cell death ligand 1 (anti-PD-L1)-treatment-naive participants with advanced/metastatic melanoma. The primary hypothesis of the study is that gebasaxturev administered either ITu or IV in combination with pembrolizumab results in a superior objective response rate (ORR) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1) based on blinded independent central review (BICR), compared to pembrolizumab alone. This study will be terminated once all participants finish treatment with V937. Participants eligible to continue to receive pembrolizumab will be transferred to MK-3475-587 study.
