Condition: Ear, Nose and Throat / Loss of Smell
Investigator: Jonathan Overdevest, MD, PhD
Status: Currently Recruiting
Our research team at Columbia University is trying to understand the impact of COVID-19 on smell and taste (chemosensory) dysfunction among adult patients from the Greater New York City area. Current areas of study include: 1) Investigation of smell and taste recovery patterns among patients with COVID-19; 2) Studies on how recovery of smell and taste after…
Condition: Eye
Investigator: Brian Marr, MD
Status: Closed
In this research study we want to learn more about treatment of advanced or recurrent retinoblastoma. For children with retinoblastoma that have an advanced stage of presentation in one eye or if they have failed all conventional treatment, eye removal is considered. This study will investigate the utility of a chemoplaque(s) to salvage eyes involved with…
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
The TARGET-HBV study engages an observational research design to conduct a comprehensive review of therapeutic outcomes for patients with chronic hepatitis B (HBV) who are currently taking tenofovir alafenamide (TAF) relative to those patients following other treatment regimens. The study will address important clinical questions regarding the management of…
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: Eye
Investigator: Stephen Tsang, MD, PhD
Status: Closed
Stargardt macular degeneration isa genetic condition, which in mostcases causes vision loss early in lifeand leads to legal blindness. Thereis currently no FDA-approvedtreatment.This trial will evaluate the safetyand effects of ALK-001, a newpotential drug treatment, on theprogression of Stargardt disease.ALK-001 is a capsule administereddaily by mouth.This…
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
The purpose of this study is to evaluate the effectiveness, safety, and tolerability of study drugs Sofosbuvir, Velpatasvir and GS-9857 in comparison to Sofosbuvir and Velpatasvir in patients infected with HCV. Information about any side effects that may occur will also be collected.
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
This study will compare the effectiveness of three different FDA approved medicines for Hepatitis C Genotype 1 patients: HARVONI , Viekira Pak and Zepatier and will observe subject experiences before, during, and after HCV treatment. Subjects will be asked to respond to several survey questionnaires and if they would allow their leftover blood collected for…
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
The purpose of this study is to evaluate the efficacy, safety, and tolerability of SOF/VEL/GS- 9857 FDC in patients infected with Hepatitis C (HCV), and previously treated unsuccessfully. Information about any side effects that may occur will also be collected.
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
This research trial is being conducted to determine the safety and efficacy of HARVONI (an FDA-approved Hepatitis C Virus medication) in HCV (genotype 1, 4, 5, an 6) infected patients who also have advanced heart failure or chronic lung disease. HARVONI has not been tested in patients with HCV and heart failure or chronic lunch disease. Subjects will take…
Condition: Liver Disease / Hepatitis
Investigator: Steven Lobritto, MD
Status: Closed
The purpose of this study is to learn more about the effects of the combination of telaprevir peginterferon alfa2b (Peg-IFN) and ribavirin (RBV) in children with chronic hepatitis C. Investigators will look at how these study drugs may affect childrens bodies and how children break down and eliminate telaprevir. Participants of this study will receive Peg-…
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…
Condition: Eye
Investigator: Tongalp Tezel, MD
Status: Closed
The abicipar is an injectable medication stored as a liquid in a single-use glass vial for delivery into the back of the eye. The active component is a protein drug that was made using bioengineering technology. It was designed to bind to and inactivate a protein called Vascular Endothelial GrowthFactor (VEGF) that plays an important role in causing AMD.…
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
The purpose of this study is to determine how safe and effective using three medications (pegylated-interferon, ribavirin and boceprevir) are in curing HCV in patients with end stage kidney disease on hemodialysis. Participants will be prescribed these three medications and will be followed closely through treatment, then for 6 months afterwards. During…
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…
Condition: Eye
Investigator: Tongalp Tezel, MD
Status: Closed
Macular degeneration is a progressive eye disease that damages the macula. The macula is the part of the eye that is responsible for central vision, which is needed to perform straight-ahead activities, such as reading, driving, or watching TV. This research is being conducted to learn about the safety and efficacy (how effectively the study drug works) of…
Condition: Liver Disease / Hepatitis
Investigator: Robert Brown, MD, MPH
Status: Closed
The purpose of this study is to see if study drug Sofosbuvir/Ledipasvir fixed-dose combination + Ribavirin (SOF/LDV FDC + RBV) are effective in treating people infected with the hepatitis C virus with genotypes 1 and 4, who have advanced liver disease with permanent liver damage (cirrhosis) and may be showing signs of liver failure or who have undergone…
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
This study will compare two experimental drugs, named Sofosbuvir/Velpatasvir/GS-9857 Fixed-Dose Combination (SOF/VEL/GS-9857 FDC) and Sofosbuvir/Velpatasvir (SOF/VEL FDC) for 12 weeks for the treatment of chronic hepatitis C virus (HCV) infection in subjects who have previously been unsuccessfully treated for chronic HCV.. An experimental drug is one that…
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.

NOTE: YOU MUST HAVE HIV AND HAVE EVER HAD HEPATITIS C TO BE ELIGIBLE FOR THIS STUDY!! ............... For individuals who have both HIV and Hepatitis C virus (HCV), heavy drinking poses serious risks to their health. We do not yet know which interventions are effective at helping individuals with HIV and HCV drink less. The goal of the study is to compare…
