The Biomarkers in the Hyperbaric Oxygen Brain Injury Treatment Trial (BioHOBIT)
Recruiting
There are no therapeutic agents that have been shown to improve outcomes from severe traumatic brain injury (TBI). Critical barriers to progress in developing treatments for severe TBI are the lack of: 1) monitoring biomarkers for assessing individual patient response to treatment; 2) predictive biomarkers for identifying patients likely to benefit from a promising intervention. Currently, clinical examination remains the fundamental tool for monitoring severe TBI patients and for subject select... Read More

A Study to Assess the Efficacy, Safety, Pharmacodynamics, and Pharmacokinetics of Tazemetostat in Combination With Lenalidomide Plus Rituximab Versus Placebo in Combination With Lenalidomide Plus Rituximab in Adult Patients at Least 18 Years of Age With Relapsed/Refractory Follicular Lymphoma.
Recruiting
The participants of this study would have relapsed/refractory follicular lymphoma. Follicular lymphoma is a type of blood cancer. It is referred to as 'relapsed' when the disease has come back after a period of improvement after that follows a treatment regimen and 'refractory' when treatment no longer works. Stage 1 of this trial will study the safety and the level that adverse effects of each of the study drug combinations can be tolerated (known as tolerability). It is also designed to esta...

Effect of Patient Preference for Intraoperative Opioid Use on Early Postoperative Quality of Recovery
Recruiting
Substituting the administration of opioids with a combination of alternative analgesics, known as opioid-free anesthesia (OFA), is gaining in popularity today and is typically administered as part of a larger multimodal strategy. However, OFA adoption is not as common today as one could expect from the potential benefits of limiting opioid use and patient involvement in the decision may impact its adoption. Relevant shared decision-making process with patients concerning the use or limited use o... Read More
