Status: Currently Recruiting
We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, ages 18-65, who have obesity with a body mass index of 30-45, and have been diagnosed with, or are at risk for, prediabetes and metabolic…

Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are conducting a research study on how insulin controls blood sugar in both healthy people and those at risk of type 2 diabetes. We are seeking adult volunteers, aged 18-65, who have body mass indices either in the lean range (18-25 kg/m2) or in the obesity range (30-45 kg/m2) but who do not have prediabetes or diabetes. Participants will undergo a…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are seeking adult volunteers with body mass index in the obesity range (30-45 kg/m2) to come in for a single study visit where they answer some health questions and have a small volume of blood drawn (25 cc/1.7 tbsp). We will measure levels of the blood sugar-lowering hormone insulin as well as glucose (sugar), certain fats, and other molecules related…
Condition: Cancer / Lymphoma
Investigator: Larisa Geskin, MD
Status: Closed
The purpose of this study is to better understand the use of Valchlor in clinical practice. Other goals include describing the demographic and clinical characteristics of disease and health outcomes of patients treated with Valchlor. Participating in this study will not influence the usual care you receive from your doctor.
Condition: Cancer / Lymphoma
Investigator: Nobuko Hijiya, MD
Status: Closed
This Phase III trial investigates if the incorporation of immunotherapy will improve progression-free survival (PFS) and maintain overall survival (OS) while simultaneously minimizing long-term morbidity and treatment-related mortality by reducing exposure to radiotherapy and high cumulative chemotherapy doses. The study will enroll patients ages 5 to 60…
Condition: Cancer / Lymphoma
Investigator: Jennifer Amengual, MD
Status: Closed
This study is being done to determine if a study drug called lenalidomide can be combined with full doses of EPOCH chemotherapy for patients with Adult T-Cell Leukemia-Lymphoma (ATLL), and to define the highest dose and longest duration of lenalidomide that can be given safely in combination with EPOCH. EPOCH chemotherapy is a combination of five…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Closed
We're conducting a research study on how much insulin is needed to control blood sugar in people who are made temporarily resistant to insulin's effects. Insulin is the main hormone (chemical signal) that the body uses to lower the levels of sugar in the blood. We are interested in looking at insulin levels because we think that lowering insulin…
Condition: Eye
Investigator: Tongalp Tezel, MD
Status: Closed
The purpose of this clinical study is to evaluate the safety and efficacy of two doses of GT005 administered as a single subretinal injection in individuals with geographic atrophy secondary to dry age-related macular degeneration (AMD) who qualify, based on genetic testing.
Condition: Cancer / Lymphoma
Investigator: Ahmed Sawas, MD
Status: Closed
The purpose of this study is to see if study drug IMO-8400 is safe and effective in the treatment of patientswith relapsed or refractory Diffuse Large B-Cell Lymphoma following conventional treatment.Examples of conventional treatment are radiotherapy, immunotherapy, chemotherapy, orradioimmunotherapy. Patients are scheduled to participate in this study…
Condition: Eye / Glaucoma
Investigator: Lama Al-Aswad, MD, MPH
Status: Closed
This study is for patients with Glaucoma. The purpose of this study is to investigate the safety and effectiveness of a study drug called Bimatoprost Sustained Release (SR) compared to treatment with eye drug Timolol. The Bimatoprost SR is an implant that is very small, is biodegradable (dissolves naturally in the body), and contains the bimatoprost drug.
Condition: Cancer / Lymphoma
Investigator: Larisa Geskin, MD
Status: Closed
This is a phase 3 clinical trial to determine the efficacy of topical SGX301 (synthetic hypericin) in combination with visible light therapy on cutaneous T-cell lymphoma (CTCL). Selected subjects can participate in 3 cycles each consisting of a 6 week treatment period where a chosen lesion will be treated with the study ointment (twice a week) followed by…
Condition: Cancer / Lymphoma
Investigator: Ahmed Sawas, MD
Status: Closed
The purpose of this study is to determine a safe dose by testingthe investigational product, AGS67E at different dose levels. Secondly, to test what effects, good and/or bad, it has on subjects with refractory or relapsed non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), prolymphocytic leukemia (PLL) or hairy cell leukemia (HCL). We will also…

Condition: Eye / Glaucoma
Investigator: Jeffrey Liebmann, MD
Status: Closed
Glaucoma is the leading cause of irreversible blindness worldwide. The most important test to detect progression is visual field testing. However, this test is very subjective, often unreliable, and variable. One of the main causes of unreliable tests is the lack of attentiveness or concentration during the test. Previous studies have shown that listening…
Research Study of New Treatment Called NT-501 (Encapsulated Cell Therapy (ECT) Implant) for Glaucoma
Condition: Eye / Glaucoma
Investigator: George Cioffi, MD
Status: Closed
Glaucoma is a given name of a group of diseases that affect the retinal ganglion cells in the eye and the optic nerve. Glaucoma cause degeneration of the retinal ganglion cells in the retina and their projections (axons) that form the optic nerve. Retinal ganglion cells and their axons transmit all of our vision information from the eye to the brain through…
