Arm Intervention/treatment
Experimental: Volixibat 20mg
Participants randomized to this arm will receive volixibat 20mg twice daily.
 Drug: Volixibat
Oral capsules, administered twice daily. Volixibat is an apical sodium-dependent bile acid transporter (ASBT) inhibitor.
Other Name: SHP626
Experimental: Volixibat 80mg
Participants randomized to this arm will receive volixibat 80mg twice daily.
 Drug: Volixibat
Oral capsules, administered twice daily. Volixibat is an apical sodium-dependent bile acid transporter (ASBT) inhibitor.
Other Name: SHP626
Placebo Comparator: Placebo
Participants in this arm will receive capsules matched to the study drug minus the active volixibat substance, twice daily.
 Drug: Placebo
Capsules matched to study drug minus active substance.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Mean change in serum bile acids [ Time Frame: Through to end of treatment, up to 21 weeks ]

Secondary Outcome Measures :
  1. Mean change in the weekly average worst daily itch score as measured by the Adult Itch Reported Outcome (ItchRO) [ Time Frame: Through to end of treatment, up to 21 weeks ]
    The Adult ItchRO is an 11-point NRS measurement of itch severity ranging from 0=no itch to 10=worst possible itch.

  2. Proportion of participants experiencing one or more of adverse perinatal outcomes [ Time Frame: Through to end of treatment, up to 21 weeks ]
  3. The incidence of adverse events [ Time Frame: Through to study completion, up to 25 weeks ]
