• LPM3770164 sustained release tablet (Drug): administrated orally
• LPM3770164 sustained release tablet simulant (Drug): administrated orally

Primary outcomes

• Treatment-emergent adverse event [from baseline to day 37]: Number of participants with treatment-emergent adverse event will be summarized by Group, System Organ Classification (SOC), Preferred Term (PT), severity and the relationship with treatment.

Secondary outcomes

• Area Under the Curve from time 0 extrapolated to infinity (AUC0-inf) [from day 1 to day 24]
• Time to maximum concentration (Tmax) [from day 1 to day 24]
• Half-life (t1/2) [from day 1 to day 24]
• ECG QTc Interval [from baseline to day 37]
