Condition(s) targeted: Anal Resting Pressure

Intervention: Coated Nifedipine Suppositories (Drug)

Phase: Phase 1/Phase 2

Status: Completed

Sponsored by: RDD Pharma Ltd

Summary

This is an open label, dose-finding study. Approximately 8 healthy subjects will be participating in this study. Within one week after the screening visit, subjects who meet all inclusion criteria and none of the exclusion criteria will enter a one day treatment period.

Clinical Details

Official title: An Open Label Study to Examine the Effect of Coated Nifedipine Suppositories on Anal Pressure in Healthy Subjects

Study design: Intervention Model: Single Group Assignment

Primary outcome: The primary efficacy parameter is change in Resting Anal Pressure from baseline.

Detailed description: After detrminig baseline resting anal pressure with a manometric test, coated Suppositories will be administered intra rectally. Subjects will take rectally a total of 3 Coated Suppositories per study. 90 minutes after each coated suppository insertion this suppository will be removed and a amnometric study will be performed: The first dose will contain 4 mg of Nifedipine and the manomentric measurement performed afterwards will be used to determine baseline anal pressures. The second dose will contain 12 mg of Nifedipine. The third dose will contain 24 mg of Nifedipine. The primary efficacy parameter is change in Resting Anal Pressure from baseline. The secondary efficacy parameters include the following:

- The ratio of change in anal pressure to plasma Nifedipine level.

- The ratio of change in anal pressure to change in blood pressure.

- The ratio of change in anal pressure to change in heart rate.
