2021年2月17日 更新者:XenoPort, Inc.

Multiple-Dose Efficacy and Safety Study of XP19986 in Subjects With Spasticity Due to Spinal Cord Injury

The purpose of this study is to evaluate efficacy and safety of treatment with XP19986 Sustained Release (SR) Tablet compared to placebo in subjects with spasticity due to spinal cord injury

研究概览

详细说明

This is a multiple-dose, randomized, placebo-controlled crossover study of the efficacy and safety of XP19986 SR1 in subjects with spasticity due to spinal cord injury. Three cohorts of subjects are randomized to receive XP19986 SR1 10 mg every 12 hrs or 20 mg every 12 hrs or 30 mg every 12 hrs in one treatment segment and placebo every 12 hrs in the alternate treatment segment. Each subject serves as their own control in this cross-over study.

参与者组/臂
干预/治疗
实验性的:XP19986 SR1 10 mg - Placebo
Following a 7 day run-in period in which participants take placebo twice a day (BID), participants are randomized to the cohort that will take XP19986 SR1 10 mg BID treatment crossing over to placebo treatment (or the reverse order). Each treatment segment follows the same pattern: 3-9 days of titration, 7 days at target dose, 3-9 days of tapering, followed by a 3-day placebo washout.
XP19986 Sustained Release (SR) 10 mg tablet dosed orally, twice a day (BID), for approximately 26 days with titration and taper periods
其他名称:
  • Sustained release Polyox WSR N750, 10 mg
Placebo tablets to match active intervention, taken twice a day (BID) for approximately 26 days with titration and taper periods. Also taken during placebo washout periods.

  • 糖丸
实验性的:XP19986 SR1 20 mg - Placebo
Following a 7 day run-in period in which participants take placebo twice a day (BID), participants are randomized to the cohort that will take XP19986 SR1 20 mg BID treatment crossing over to placebo treatment (or the reverse order). Each treatment segment follows the same pattern: 3-9 days of titration, 7 days at target dose, 3-9 days of tapering, followed by a 3-day placebo washout.
