Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Visual Analog Scale for Itching: Circadian 2 Hours AW | 7 days | To assess the effects of circadian rhythm on pruritus, participants will record itch intensity using a visual analog scale (VAS) at the following time points after waking (AW): AW+2h for 7 days. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) of 7 daily measurements will be reported. |
| Primary | Visual Analog Scale for Itching: Circadian 4 Hours AW | 7 days | To assess the effects of circadian rhythm on pruritus, participants will record itch intensity using a visual analog scale (VAS) at the following time points after waking (AW): AW+4h for 7 days. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) of 7 daily measurements will be reported. |
| Primary | Visual Analog Scale for Itching: Circadian 6 Hours AW | 7 days | To assess the effects of circadian rhythm on pruritus, participants will record itch intensity using a visual analog scale (VAS) at the following time points after waking (AW): AW+6h for 7 days. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) of 7 daily measurements will be reported. |
| Primary | Visual Analog Scale for Itching: Circadian 8 Hours AW | 7 days | To assess the effects of circadian rhythm on pruritus, participants will record itch intensity using a visual analog scale (VAS) at the following time points after waking (AW): AW+8h for 7 days. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) of 7 daily measurements will be reported. |
| Primary | Visual Analog Scale for Itching: Circadian 10 Hours AW | 7 days | To assess the effects of circadian rhythm on pruritus, participants will record itch intensity using a visual analog scale (VAS) at the following time points after waking (AW): AW+10h for 7 days. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) of 7 daily measurements will be reported. |
| Primary | Visual Analog Scale for Itching: Circadian 12 Hours AW | 7 days | To assess the effects of circadian rhythm on pruritus, participants will record itch intensity using a visual analog scale (VAS) at the following time points after waking (AW): AW+12h for 7 days. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) of 7 daily measurements will be reported. |
| Primary | Visual Analog Scale for Itching: Treatment 0 min | 0 minutes after applying topical cream | To assess the effects of naltrexone 1% or placebo cream on pruritus, participants will record itch intensity using a visual analog scale (VAS) at 0 minutes after applying cream for 3 pruritis attacks in 1 week. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) over 3 pruritis attacks will be reported. |
| Primary | Visual Analog Scale for Itching: Treatment 20 min | 20 minutes after applying topical cream | To assess the effects of naltrexone 1% or placebo cream on pruritus, participants will record itch intensity using a visual analog scale (VAS) at 20 minutes after applying cream for 3 pruritis attacks in 1 week. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) over 3 pruritis attacks will be reported. |
| Primary | Visual Analog Scale for Itching: Treatment 40 min | 40 minutes after applying topical cream | To assess the effects of naltrexone 1% or placebo cream on pruritus, participants will record itch intensity using a visual analog scale (VAS) at 40 minutes after applying cream for 3 pruritis attacks in 1 week. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) over 3 pruritis attacks will be reported. |
| Primary | Visual Analog Scale for Itching: Treatment 1 Hour | 1 hour after applying topical cream | To assess the effects of naltrexone 1% or placebo cream on pruritus, participants will record itch intensity using a visual analog scale (VAS) at 1 hour after applying cream for 3 pruritis attacks in 1 week. VAS ranges from 0mm (no itch) to 100mm (unbearable itch). The mean (in millimeters) over 3 pruritis attacks will be reported. |
