A Prospective, Randomized, Controlled Clinical Pilot Trial Investigating the Partial Down-titration of Guideline-directed Medical Therapy in Patients With Heart Failure in Remission.
Summary: Heart failure (HF) is a chronic condition that is characterized by a weakened and enlarged heart. It typically causes symptoms such as breathlessness and swelling of the legs, and it is a serious illness that shortens life expectancy. In recent years, new medicines have been developed that can improve heart function and help patients with HF live longer. HF patients with reduced heart function typ...
Response to Combined Trigeminal and Occipital Nerve Stimulation for the Preventive Treatment in Chronic Cluster Headache: The RESPONSE-II Study
Summary: This is a limited open-label study being performed at two centers in the Netherlands. All participants will receive the same treatment, and both the patients and doctors will know what that treatment is. The goal is to see how safe and effective the PRIMUS system is for preventing Chronic Cluster Headaches (CCH) in people who haven't responded well to the drug verapamil. The study will also look a...
A Randomized Phase 1/2 Trial of Low Dose Anti-thymocyte Globulin (ATG) With Subsequent Adalimumab or Verapamil in New Onset Type 1 Diabetes
Summary: This multi-center randomized controlled trial will assess the safety and efficacy of ATG followed by either adalimumab or verapamil in preserving insulin secretion 2 years from randomization in persons aged 9 to \<21 with recent-onset stage 3 T1D.
Pharmacokinetics and Safety of Commonly Used Drugs in Lactating Women and Breastfed Infants
Summary: Over half of women in the US who are breastfeeding their infants take prescription drugs. You are being asked to participate in this study because you are breastfeeding your infant and are currently taking, as part of your medical care, at least one of the drugs we are studying. We are interested in studying drugs commonly prescribed to women who are breastfeeding so we can learn more about the am...
Efficacy and Safety of HB-1 for Panic Disorder: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial
Summary: The purpose of this study is to determine the safety and efficacy of HB-1, versus placebo and two monotherapies, in male and female adult patients aged 18 to 65 years, inclusive, with Panic Disorder.
Precision Administration of Anti-thymocyte Globulin With or Without Verapamil in Adolescents and Young Adults With Type 1 Diabetes
Summary: T cell directed therapy, anti-thymocyte globulin (ATG), in low doses, has been shown to lower HbA1c and preserve endogenous insulin production (measured by C-peptide) in individuals with recently diagnosed type 1 diabetes (T1D). However, not all individuals who received ATG responded to the therapy (i.e., non-responders). Additionally, use of ATG alone does not address inherent beta cell stress. A...
A Phase I/II Double-blind, Randomized, Placebo-controlled Trial to Preserve Residual Insulin Secretion in Children With Recent Onset Type 1 Diabetes by Giving Verapamil
Summary: The objective of this trial is first to evaluate safety and then the effect on preservation of residual beta cell function also clinical efficacy by treatment with Verapamil in children with recent onset Type 1 diabetes. Patients are included with the following inclusion criteria; * Informed consent given by patients and caregivers/parents Type 1 diabetes according to the ADA classification within...
Title Fractioned CO2 Laser in the Treatment of Chronic Phase Peyronie's Disease
Summary: Peyronie's Disease (PD) is a fibrosing disorder of the penis where scar tissue (composed of excessive and disorganized collagen) known as a plaque, forms along the shaft of the penis. This plaque can lead to permanent penile deformity (curvature, narrowing, indentation, hinging), loss of penile length, erectile dysfunction, and pain during intercourse. Research has shown PD to negatively impact th...
Use of Adenosine to Determine the Electrophysiological Mechanism of Premature Ventricular Contractions
Summary: Unblinded, controlled, non-randomized, mechanistic study to determine whether physiological mechanisms underlying PVC are sensitive to adenosine. One hundred subjects undergoing clinically-indicated, standard-of-care cardiac electrophysiology study (EPS) procedure for PVCs will receive adenosine and/or verapamil to learn if their arrhythmias are inducible similarly to sustained ventricular tachyca...
Treatment Effects of Bisoprolol and Verapamil in Symptomatic Patients With Non-obstructive Hypertrophic Cardiomyopathy
Background: Hypertrophic cardiomyopathy (HCM) is characterized by hypertrophy of the left ventricular wall and a hypercontracted state of the sarcomeres. This narrows the left ventricular cavity, but though the left ejection fraction is increased the stroke volume and the cardiac output cannot be fully compensated. The disease manifestations can be mild or develop into severe functional limitations and devast...
Effect of Sacubitril/Valsartan on Cardiac Function Assessed by Cardiac Magnetic Resonance (CMR) in Hypertensive Patients Stratified by Body Mass Index (BMI): A Real World Study
Summary: The purpose of this study is to investigate the effect of sacubitril/valsartan on cardiac function assessed by cardiac magnetic resonance (CMR) in hypertensive patients stratified by BMI.
Intraarterial Verapamil for Neuroprotection in Ischemic Stroke
Summary: The purpose of this research study is to test an experimental procedure called intra-arterial delivery of verapamil in patients diagnosed with acute ischemic stroke. This study investigates the safety of intra-arterial delivery of verapamil, a drug used to treat vasospasm (spasm of a blood vessel), and how it affects recovery from stroke. Recruitment is limited to patients that have received mecha...
