We are conducting a research study on how psoriasis might be caused or worsened by high levels of the blood sugar-lowering hormone insulin. We are seeking people with plaque psoriasis, ages 18-65, who are overweight or obese with a body mass index of 25-35. Participants will have blood drawn and small skin biopsies taken from psoriasis plaques and nearby…
The Columbia Otolaryngology Department is interested in understanding the intersection of vaping, smell, and taste and their impact on individuals' preferences for certain flavors. Participation will involve answering a series of questionnaires in addition to completing a formal evaluation of your smell and taste with standardized measurements. You can…
The purpose of this study is to examine the causes and pathology of alopecia areata and other hair and skin disorders. Skin biopsies and blood and/or clinical information collected in the study will be used for research aiming at developing new options for the treatment of alopecia areata and other skin and hair disorders.
Genetic studies help us to understand why some people develop certain diseases while others don't and also provide important clues about how best to treat the disease.
The purpose of this research study is to evaluate the safety and effectiveness (how well the study drug works) of NBTRX3 administered via intratumoral injections (injected directly into tumor) and used together with radiotherapy or radiotherapy combined with cetuximab, and how it compares with radiotherapy alone, or radiotherapy combined with cetuximab.…
The use of electronic cigarettes, also known as e-cigs or vaping, has increased among former smokers and young adults who have never smoked. Relatively little is known, however, about their health effects (whether they are adverse, have no effect, or are beneficial). The purpose of this research study is to evaluate (1) the association of e-cig use with…
This is a four-session study in which we will be recruiting existing cigarette smokers to explore the competitive dynamics between memory encoding and memory retrieval. To participate, you will first go through a phone screening to determine eligibility and learn about the study. Then you will be asked to visit our facility at the Morningside Campus of…
The purpose of this study is to study ADU-S100 and pembrolizumab in patients with recurrent or metastatic head and neck squamous cell cancer (HNSCC). This study aims to evaluate how safe and effective this drug combination is at treating your cancer. These drugs are thought to work by interacting with your immune system to in order to more effectively…
There are two study questions we are asking in this randomized phase II/III trial based on a blood biomarker, Epstein Barr virus (EBV) deoxyribonucleic acid (DNA) for locoregionally advanced non-metastatic nasopharyngeal cancer. All patients will first undergo standard concurrent chemotherapy and radiation therapy. When this standard treatment is completed…
The study involves research about MGA271 in combination with Keytruda. MGA271 targets cancer cells that make a lot of a protein called B7-H3. Another way to say it is that the cells "overexpress" the protein. Very few normal cells express B7-H3. MGA271 is though to work by recognizing cancer cells that overexpress B7-H3 and directing the body…
