Biomarker Platform (Virtual Nodule Clinic) for the Management of Indeterminate Pulmonary Nodules
Recruiting
This clinical trial studies whether a biomarker platform, the Virtual Nodule Clinic, can be used for the management of lung (pulmonary) nodules that are not clearly non-cancerous (benign) or clearly cancerous (malignant) (indeterminate pulmonary nodules \[IPNs\]). The management of IPNs is based on estimating the likelihood that the observed nodule is malignant. Many things, such as age, smoking history, and current symptoms, are considered when making a prediction of the likelihood of malignanc... Read More

Safety and Efficacy of a Drug Eluting Slim Modiolar Electrode Array
Recruiting
This clinical study will test a new type of cochlear implant known as CI632D. This experimental cochlear implant has been designed to slowly release a drug called dexamethasone. Dexamethasone works to ease inflammation and reduce tissue injury, which is common after any type of surgery. The goal is to learn if the dexamethasone in the CI632D implant lessens these reactions inside the ear following surgery and if this makes the implant work as well, or even better, in improving hearing than what...
