Study Groups

Sequence A

Eligible subjects will be treated for 4 periods with either velusetrag 15 mg once a day (2 periods) or placebo (2 periods), with a wash-out period of 2 weeks between treatment periods.

The progression order of this sequence is: velusetrag first intervention 4 weeks, 2 weeks of wash-out period, then second intervention of placebo for 4 weeks, 2 weeks of wash-out period, then third intervention of velusetrag for other 4 weeks, 2 weeks of wash-out period and last 4 weeks of placebo as fourth intervention.

Group Type: OTHER

Velusetrag 15 mg once daily for 4 weeks.

Intervention Type: DRUG

Subjects will be randomly allocated in a blinded fashion to 1 out of the 4 treatment sequences (each sequence include 4 periods, 2 periods with velusetrag and 2 periods with placebo). There will be a wash-out period between each treatment period.

Placebo once daily for 4 weeks.

Intervention Type: DRUG
