Study of Combinations of REGN2810, Chemotherapy, and Ipilimumab vs. Pembrolizumab Monotherapy in Patients with Non-Small Cell Lung Cancer

Condition: Cancer / Lung Cancer
Investigator: Naiyer Rizvi, MD
Status: Closed
This study is being done to determine if REGN2810 (anti-PD-1) in combination with ipilimumab (anti-CTLA-4) plus initial platinum-based doublet chemotherapy, or REGN2810 in combination with ipilimumab will prolong how long you live without your disease progressing compared to the standard of care pembrolizumab (anti-PD-1) monotherapy treatment. Neither…

Study of IW-3300 in Patients with Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS)

Condition: Urology
Investigator: Svjetlana Lozo, MD, MPH
Status: Closed
The purpose of this study is to find out if IW-3300, an investigational new drug, helps bladder pain when given as a rectal (inserted into the anus) foam. The study will test IW-3300. IW-3300 is a new drug that has been developed for treating people like you with interstitial cystitis/bladder pain syndrome. It is not yet approved by the United States Food…

Lung Cancer Patient Survey Study on Technology Support for Treatment Preparedness

Condition: Cancer / Lung Cancer
Investigator: Alicia Matthews
Status: Closed
We are conducting a survey to gather feedback about lung cancer patients experience with treatment and the challenges you faced. Your insights can help shape better care for future patients and explore how technology can be of help! The survey takes 30-40 minutes, and eligible participants who complete it will receive a gift card. Interested in…

Testing Whether the Use of Brain Scans Alone vs. Brain Scans Plus Brain Radiation Affects Lifespan in Patients With Small Cell Lung Cancer

Condition: Cancer / Lung Cancer
Investigator: Simon Cheng, MD, PhD
Status: Closed
We are doing this study because we want to find out if MRI brain scans alone is better or worse than MRI brain scans plus preventative brain radiation for patients with small lung cancer. The usual approach for patients with small cell lung cancer is prophylactic cranial irradiation. If you decide to take part in this study, you will either receive PCI for…

Brain imaging in bipolar depression to understand the role of inflammation in its treatment.

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD, PhD
Status: Closed
This is a research study to understand what causes bipolar disorder and how medications treat bipolar depression. Particularly, we are looking at the importance of inflammation in the process. If you participate, you will receive an experimental medication for your depression named ethyl eicosapentaenoic acid (ethyl EPA), an omega 3 fatty acid. You will…

Research Study offering Treatment for Self-Injury (Bipolar Disorder)

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Jeffrey Miller, MD
Status: Closed
The goal of this study is to examine how effective and well-tolerated a possible new treatment for individuals who injure themselves frequently will be. All research procedures can be done from home no in-person visits are required. We are studying a minimal-risk form of electrical brain stimulation called transcranial direct current stimulation, or tDCS.…

Brain imaging in bipolar depression to be able to predict who will respond to antidepressant treatment

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD, PhD
Status: Closed
We are trying to understand what causes bipolar disorder and how medications treat bipolar depression. If you participate, you will have two different brain scans (MRI and PET scan). You will also have antidepressant treatment for free. We will then be able to see whether information on the brain scans connects with how people do on the medications. The…

Adjuvant Lung Cancer Enrichment Marker Identification and Sequencing Trial (ALCHEMIST)

Condition: Cancer / Lung Cancer
Investigator: Brian Henick, MD
Status: Closed
This purpose of this study is to determine whether the tumor cells of lung cancer patients contain changes to the DNA sequence of two proteins found on the cells surface- ALK and EGFR. If the tumor contains changes to the DNA of one of these proteins, the patient may be invited to participate on a trial that will look at drugs which may target tumors that…

A registry for patients with Overactive Bladder (OAB)

Condition: Urology
Investigator: Matthew Rutman, MD
Status: Closed
This study is for adults with Overactive Bladder. The purpose of this registry is to collect information about patients who have Overactive Bladder (OAB) and who are receiving either mirabegron or another approved antimuscarinic medication (single drug). To collect this information, the study Sponsor has created a research registry. A registry is a kind of…

Brain imaging in bipolar depression to understand the antidepressant mechanism of lurasidone (Latuda).

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD, PhD
Status: Closed
We are trying to understand what causes bipolar disorder and how medications treat bipolar depression. Particularly, we are looking at the importance of dopamine signaling in the process. If you participate, you will have two different brain scans (MRI and PET scan). You will also have treatment for your depression with an FDA approved medication,…

Lumateperone for the Treatment of Bipolar Disorder

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: David Hellerstein, MD
Status: Closed
This study is a double-blind and placebo-controlled study to assess its efficacy of the new drug Lumateperone for patients with Major Depressive Episodes associated with Bipolar I and Bipolar II disorder. Lumateperone is thought to exert its antidepressant effect through interaction with sereotogenic, dopaminergic, and glutamergic neurotransmitter targets.…

Validation of electronic (web-based and smartphone) administration of measures of pelvic floor dysfunction

Condition: Urology
Investigator: Doreen Eleanor Chung, MD
Status: Closed
You will be randomly assigned to complete questionnaires via either a paper format, web-based format, or smartphone format. About 2 weeks later but before treatment begins, you will be asked to complete a different form of the questionnaire either in the office or at home. You will be emailed and/or called by research staff to remind you to complete the…

MRI Effects of D-cycloserine & Lurasidone in Bipolar Depression

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Joshua Kantrowitz, Md
Status: Closed
We will evaluate the D-cycloserine (DCS) and lurasidone with MRI measurement of brain responses to DCS. DCS is a drug that works on the same brain receptor as ketamine. DCS is not approved by the FDA for bipolar depression. Study participants will receive a dose of lurasidone or placebo in one MRI and a dose of DCS in another, followed by an optional follow…
