NCT05241860
This phase II trial examines antiandrogen therapy interruptions in patients with hormone-sensitive prostate cancer that has spread to other places in the body (metastatic) responding exceptionally well to androgen receptor-pathway inhibitor therapy. The usual treatment for patients with metastatic prostate cancer is to receive hormonal medications including a medication to decrease testosterone levels in the body and a potent oral hormonal medication to block growth signals from male hormones (like testosterone) in the cancer cells. Patients whose cancer is responding exceptionally well to this therapy may take a break from these medications according to their doctor's guidance. This trial may help doctors determine if stopping treatment can allow for testosterone recovery.
NCT02566473
Aim 1. Establish a national registry of diverse patients of orthopedic surgeons representing all regions of the country and varied hospital and surgeon practice settings (e.g., urban/rural, low and high volume) to ensure that registry analyses and research reflect typical clinical practice thereby providing optimal guidance for patients, clinicians, and national healthcare policymakers. Collect pre-operative and post-operative patient reported outcomes (PROs) for pain and function. Aim 2: Develop new and transformative comparative effectiveness tools useful to both clinical practice and healthcare policy. Aim 3. Broadly disseminate surveillance reports for adverse events, such as implant revision, hip dislocation, knee manipulation, and identify important variation to inform quality improvement priorities.
NCT04464707
The primary objective of the study is to evaluate the effectiveness of fremanezumab as compared to placebo for the preventive treatment of chronic migraine (CM). Secondary objectives are to further demonstrate the efficacy of Fremanezumab as compared to placebo for the preventive treatment of CM, to evaluate the safety and tolerability of Fremanezumab in the preventive treatment of CM and to evaluate the immunogenicity of Fremanezumab and the impact of antidrug antibodies (ADAs) on clinical outcomes in participants exposed to Fremanezumab The total duration of the study is planned to be 75 months.
NCT03549559
The overall goal of this PET-MR imaging trial is to evaluate 11C-Martinostat, a histone deacetylase targeted radioligand, in patients with aortic stenosis, individuals with diabetes, and healthy volunteers.
NCT05453162
Proposed research will examine time-of-day effects on trauma-related fear extinction using Prolonged Exposure Therapy (PE) telemedicine for Posttraumatic Stress Disorder (PTSD) in the National Center for PTSD (NCPTSD). The primary mechanistic outcome measure will be change in psychophysiological reactivity to script-driven imagery (SDI-PR) measured, in person, at pre-treatment, after 5 PE sessions (mid-treatment), and after all 10 PE sessions (post-treatment). A secondary mechanistic outcome will be session-to-session reduction in peak subjective units of distress (SUDS) ratings to imaginal exposures. The primary clinical outcome will be change in Clinican Administered PTSD Scale (CAPS-5) severity score; a secondary clinical outcome will be session-to-session reduction in self-reported PTSD symptoms using the PTSD checklist (PCL-5). Participants meeting inclusion criteria (described below) will be randomized to either PE sessions that begin from 07:00 to a time no later than 2 hours past a participant's customary rise time, or to the last treatment session of the day beginning at 16:00 or later (26 per arm). Participants will complete daily at-home imaginal-exposure homework within the same time frame as their PE sessions are scheduled, i.e., within 2 hours of awakening for morning (AM) group and between 16:00 and 2 hours before bedtime for late afternoon (PM) group.
NCT06753916
The main objective of this study is to determine the safety of Ex Vivo Cross Linking (CXL) of donor corneal tissue in participants who have undergone high-risk penetrating keratoplasty.
NCT05172973
The objective of this study is to establish the safety and effectiveness of the Edwards SAPIEN X4 Transcatheter Heart Valve (THV) in subjects who are at high or greater risk with a failing aortic bioprosthetic valve.
NCT05820087
The purpose of this trial is to evaluate the effectiveness and safety of the HistoSonics Edison System for the destruction of kidney tissue by treating primary solid renal tumors.
NCT02860975
The purpose of this study is to define the safety and the biochemical-physiological response of prolonged exposure to a normobaric low-oxygen environment in healthy volunteers.
NCT06253221
The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of mavacamten in adolescent patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM).
NCT06077773
Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Effects of EP262 in Subjects with Chronic Spontaneous Urticaria
NCT06389656
Weight stigma and weight bias internalization (WBI) are common among adolescents at higher weight statuses. WBI is associated with negative physical and mental health outcomes. The current study aims to test intervention for weight stigma and WBI in conjunction with an evidence-based adolescent weight management program. Adolescents (ages 13-17) will participate in a 20-week program tailored to improve WBI and weight-related health behaviors in tandem. Primary outcomes are feasibility and acceptability of the developed intervention, assessed following the 20-week intervention.
NCT05178862
This is a multicenter, randomized, double-blind study of two treatment regimens for invasive candidiasis included candidemia. Subjects will receive intravenous echinocandin followed by oral ibrexafungerp (SCY-078) vs intravenous echinocandin followed by oral fluconazole.
NCT06493604
A Randomized, Double-Masked, Vehicle-Controlled Parallel Group Clinical Trial to Assess Efficacy and Safety of 0.25% Reproxalap Ophthalmic Solution Compared to Vehicle in Subjects with Dry Eye Disease
NCT06963021
The study will evaluate the efficacy of NBI-1065845 compared with placebo as an adjunctive treatment in participants with MDD on improving symptoms of depression.
NCT04579380
This trial studies how well tucatinib works for solid tumors that make either more HER2 or a different type of HER2 than usual (HER2 alterations) The solid tumors studied in this trial have either spread to other parts of the body (metastatic) or cannot be removed completely with surgery (unresectable). All participants will get both tucatinib and trastuzumab. People with hormone-receptor positive breast cancer will also get a drug called fulvestrant. The trial will also look at what side effects happen. A side effect is anything a drug does besides treating cancer.
NCT04447118
This is a randomized, positive-controlled, open-label, international multicenter, Phase 3 clinical study to compare the efficacy and safety of pyrotinib versus docetaxel in patients with advanced non-squamous NSCLC harboring a HER2 exon 20 mutation who failed platinum based chemotherapy.
NCT03904693
Combination therapy in pulmonary arterial hypertension (PAH) has been the subject of active investigation for more than a decade, with the benefit of targeting different pathways known to be involved in the pathogenesis of the disease. Adherence to prescribed therapy has an impact on clinical outcomes. Reducing the pill/tablet count and frequency has a major impact on patients' adherence to therapies and therefore the observed clinical outcomes. One way to simplify treatment is to use fixed-dose combination (FDC) products that combine multiple treatments targeting different pathways into a single tablet. This study aims to demonstrate that the FDC of macitentan and tadalafil is more effective than therapy with 10 mg of macitentan alone or 40 mg of tadalafil alone. This phase 3 study will evaluate the efficacy and safety at 16 weeks of an FDC (macitentan 10 mg and tadalafil 40 mg) against these two PAH-approved therapies given as monotherapy to further confirm the added value of the FDC.
NCT05983198
This is an open label, phase I/II, multi-center study in adult participants with metastatic hormone sensitive prostate cancer (mHSPC) and with metastatic castration resistant prostate cancer (mCRPC) who have received prior anti-cancer treatment and have a positive 68Ga-PSMA-11 PET scan. The purpose of this study is to learn if the study drug, \[225Ac\]Ac-PSMA-R2, is safe and tolerable, and has anti-tumor activity in treated patients. Enrollment of all participants was not completed. The evaluated radioligand showed acceptable safety but limited benefit in metastatic prostate cancer
NCT02036931
