Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Sulfamethoxazole + MMX placebo	Drug: sulfamethoxazole + MMX placebo; 800 mg sulfamethoxazole/160 mg trimethoprim twice daily (BID) + MMX Mesalazine/mesalamine placebo once daily (QD) orally for 3 days, then a single dose of 800 mg sulfamethoxazole/160 mg trimethoprim + single does of MMX Mesalazine/mesalamine placebo orally on Day 4.
Experimental: Sulfamethoxazole + MMX Mesalazine/mesalamine	Drug: Sulfamethoxazole + MMX Mesalazine/mesalamine; 800 mg sulfamethoxazole/160 mg trimethoprim BID + 4.8 g MMX Mesalazine/mesalamine QD for 3 days, then a single dose of 800 mg sulfamethoxazole/160 mg trimethoprim + a single dose of 4.8 g MMX Mesalazine/mesalamine on Day 4; Other Names: Lialda

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Plasma Concentration Versus Time Curve Within a Dosing Interval at Steady-State (AUCss) for Sulfamethoxazole	AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure of how much and how long a drug stays in a body.	Assessed over a 24-hour period starting post-dose on day 4
Maximum Plasma Concentration at Steady-State (Cmaxss) for Sulfamethoxazole	Cmax is a term that refers to the maximum (or peak) concentration that a drug achieves in the body after the drug has been administrated.	Assessed over a 24-hour period starting post-dose on day 4
