What this phase means
This study does not use the classic phase 1–4 drug ladder. It may be a device, a behavior program, a surgery timing study, or an early feasibility test.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are carbon monoxide measurement via smokerlyzer. The registry lists allocation as na. The investigators will pursue two specific aims: (1) to monitor the extent of heme oxygenase induction (by measuring endogenous CO production) in relationship to the extent of hepatic resection or ablation(2) to assess the production of CO in patients following liver resection or ablation and correlate these findings to the rate of liver regeneration and liver function.
They plan to enroll about 125 people at Englewood. Taking part typically means study visits and measurements plus check-ins.
Official title (unrewritten)
Postoperative Heme Oxygenase Induction and Carbon Monoxide Production as a Novel Method to Assess Hepatic Regeneration and Predict Hepatic Related Morbidity After Partial Hepatectomy
Interventions: carbon monoxide measurement via smokerlyzer
Primary outcome (registry wording): correlation of carbon monoxide levels in exhaled breath with quantity and quality of liver regeneration
