Clinical Trial Summary

This is a phase I, open-label, fixed-sequence study in healthy Chinese subjects, performed at a single study centre. Cohort A will assess the Pharmacokinetic (PK) profile of rongliflozin when administered alone and the combination with rifampicin; Cohort B will assess the PK profile of rongliflozin when administered alone and combination with probenecid.

Primary	rongliflozin: The peak concentration (Cmax) ratios of geometric means of rongliflozin+rifampicin relative to rongliflozin alone.	To assess the effect of rifampicin on the Cmax of rongliflozin	from 0 hour(pre-dose,within 30mins)to 5 days after rongliflozin dosing
Primary	rongliflozin: AUC ratios of geometric means of rongliflozin+probenecid relative to rongliflozin alone.	To assess the effect of probenecid on the AUC of rongliflozin	from 0 hour(pre-dose,within 30mins)to 5 days after rongliflozin dosing
Primary	rongliflozin:Cmax ratios of geometric means of rongliflozin+probenecid relative to rongliflozin alone.	To assess the effect of probenecid on the Cmax of rongliflozin	from 0 hour(pre-dose,within 30mins)to 5 days after rongliflozin dosing
Secondary	The time to peak (Tmax) of Rongliflozin.	To assess the effect of rifampicin and probenecid on the Tmax of rongliflozin	from 0 hour(pre-dose,within 30mins)to 5 days after rongliflozin dosing
Secondary	pharmacology (PD) of rongliflozin: cumulative urine glucose excretion every 24 hours	evaluate the cumulative urine glucose excretion every 24 hours after rongliflozin administration.	from 0 hour to 5 days after rongliflozin dosing
Secondary	the number of participants with adverse events (AE) in Cohort A	To evaluate the safety and tolerability of single dose of rongliflozin and combination of rifampin	from screening to 3 days after last dose of rifampicin
Secondary	the number of participants with adverse events (AE) in Cohort B	To evaluate the safety and tolerability of single dose of rongliflozin and combination of probenecid	from screening to 3 days after last dose of probenecid
