Smelling the Juice: Functional Smell and Taste Preferences in Vaping and Cigarette Smoking

Condition: Addiction / Nicotine
Investigator: Jonathan Overdevest, MD, PhD
Status: Currently Recruiting
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…

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 C2 CryoBalloon Focal Ablation System for Patients with Barrett's Esophagus

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Closed
This research study will look at a newer treatment option for Barrett's Esophagus (BE) which uses nitrous oxide to freeze unwanted tissue. The most commonly used treatment method is Radiofrequency Ablation (RFA) which uses heat to destroy the pre-cancerous tissue. Nitrous Oxide ablation using the C2 CryoBalloon Focal Ablation System, an FDA-cleared…

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…

VapeScan Heart and Lung Study

Condition: Addiction / Nicotine
Investigator: Ana Navas-Acien, MD, PHD, MPH
Status: Closed
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…

Cigarette Smokers Wanted for Research Study Examining the Effects of Nicotine on Attention, Memory, and Perception

Condition: Addiction / Nicotine
Investigator: Mariam Aly, PhD
Status: Closed
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…

A study for patients with untreated dysplastic Barrett's Epithelium using the Coldplay CryoBallon Focal Ablation System

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Closed
C2 Therapeutics is currently enrolling patients to participate in the Coldplay 3 clinical trial. Coldplay 3 is evaluating the effectiveness of the Coldplay CryoBalloon Focal Ablation System in patients with Barrett's esophagus who have not yet received treatment. Participants will undergo treatment with the Coldplay CryoBalloon Focal Ablation System…

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 study for patients with Barrett's esophagus using a Wide Area Transepithelial Sample Esophageal Biopsy (WATS) kits for analysis

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Closed
The purpose of this study is to evaluate a new technique called Wide Area Transepithelial Sample 3-Dimensional Esophageal Biopsy (WATS) with computer assisted method of analysis of brush biopsy. This study will assess whether performing standard biopsies in addition to the WATS brush biopsies identifies more patients with dysplasia than does performing…

Eradicating Barrett's Esophagus Using Radiofrequency Ablation or a Novel Hybrid Argon Plasma Coagulation Technique (BURN)

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Closed
The purpose of the study is to compare two types of endoscopic treatments in patients with Barretts esophagus (BE) with abnormal cells (dysplasia); radiofrequency ablation (RFA) and hybrid argon plasma coagulation (H-APC). H-APC is a newer technique in the treatment of BE and has not been adequately studied and is not approved by the FDA for routine use.…
