A Study of Carbon-14-Labelled [14C] LY3437943 in Healthy Male Participants
Study Details
Study Description
Brief Summary
The main purpose of this study is to is to look at how much LY3437943 gets into the bloodstream and how long the body takes to get rid of it in healthy male participants. This study will involve a single dose of 14C radiolabeled LY3437943. his means that a radioactive tracer substance, C14, will be incorporated into the study drug to investigate the study drug and its breakdown products and to find out how much of these pass from blood into urine, feces and expired air.
The study will last up to approximately 15 weeks including the screening period of 28 days.

Have a history of constipation or have had acute constipation within 3 weeks prior to check-in
-
Have evidence of active renal disease (eg, diabetic renal disease, polycystic kidney disease) or an estimated creatinine clearance of less than 70 mL/minute, calculated using the Chronic Kidney Disease-Epidemiology equation
-
Have a history or presence of pancreatitis (history of chronic pancreatitis or idiopathic acute pancreatitis) and/or elevation in serum amylase or lipase (greater than 1.5-fold the ULN) at screening
-
Have used or plan to use over-the-counter or prescription medication, and/or dietary or herbal supplements (with the exception of vitamin supplements, acetaminophen and/or thyroid replacement therapy) within 14 days or 5 half-lives (whichever is longer) prior to dosing and for the duration of the study, including any medications that reduce GI motility, including, but not limited to, anticholinergics, antispasmodics, 5 hydroxytryptamine-3 receptor antagonists, dopamine antagonists, and opiates
-
Have had exposure to significant radiation within 12 months prior to dosing (eg, serial x-ray or CT scans, barium meal, being employed in a job requiring radiation exposure monitoring)
