Outcome Measures
Primary Outcomes (4)
Average Visual Analog Scale at Baseline
At study visits, participants recorded a mark for pruritus severity on a 10-cm horizontal line. This thermometer-type scale was marked with ratings of "no itch" (0 cm) and worst imaginable itch" (10 cm). Average Visual Analog Scale (VAS) (average itch over the past 24 hours) was recorded. Higher scores indicated worse outcome.
At Baseline
Average Visual Analog Scale at Week 2
At study visits, participants recorded a mark for pruritus severity on a 10-cm horizontal line. This thermometer-type scale was marked with ratings of "no itch" (0 cm) and worst imaginable itch" (10 cm). Average VAS (average itch over the past 24 hours) was recorded. Higher scores indicated worse outcome.
At Week 2
Average Visual Analog Scale at Week 4
At study visits, participants recorded a mark for pruritus severity on a 10-cm horizontal line. This thermometer-type scale was marked with ratings of "no itch" (0 cm) and worst imaginable itch" (10 cm). Average VAS (average itch over the past 24 hours) was recorded. Higher scores indicated worse outcome.
At Week 4
Average Visual Analog Scale at Week 8
At study visits, participants recorded a mark for pruritus severity on a 10-cm horizontal line. This thermometer-type scale was marked with ratings of "no itch" (0 cm) and worst imaginable itch" (10 cm). Average VAS (average itch over the past 24 hours) was recorded. Higher scores indicated worse outcome.
At Week 8

Eligibility Criteria
You may qualify if:
- Subjects meeting all of the following criteria will be eligible for study entry:
- Males or females who are at least 18 years and no more than 80 years of age at Screening.
- Must have PN (defined as the presence of pruritic nodules due to chronic pruritus,) of more than 6 weeks duration despite treatment with current therapies such as antihistamines or corticosteroids ("treatment resistant" PN).
- Must have PN lesions on both arms, both legs, and/or the trunk (ie, the lesions must not be localized).
- Must have a VAS pruritus score of 70 or greater within 72 hours of Baseline.
- Males, non-fecund females (ie, surgically sterilized, if procedure was done 12 months before screening or subject is postmenopausal, without menses for 12 months before screening), or females of childbearing potential using an acceptable method of birth control for a period of 35 days before the first dosing, and all females must have a negative pregnancy test at the screening and baseline visits:
- Note 1: Acceptable methods of birth control include any one of the following:
- abstinence, vasectomized sexual partner, hormonal methods (ie, birth-control pill, hormonal IUD, Depo-Provera, implants, patch, intravaginal device \[NuvaRing\]), intrauterine device (IUD \[copper banded coils\]), diaphragm, cervical cap, or condom with spermicidal jelly or foam. Subjects using oral contraceptives must also use a reliable backup method of birth control during the study and until the first menses after the last dose of study medication or for 14 days menses after the last dose of study medication.
- Willing and able to understand and provide written informed consent.
- Willing and able to comply with study requirements and restrictions including the discontinuation of all current therapies for pruritus.
- Subjects must be in good health as determined by medical history, physical examination, and results of Electro Cardio Gram (ECG) and clinical laboratory tests (including urinalysis).
- Agreeing to confidential use and storage of all data and use of all anonymized data for publication including scientific publication.
You may not qualify if:
- Subjects not eligible for the study are those who:
- Have chronic pruritus due conditions other than PN, such as the following conditions:
- Lichen simplex chronicus
- Lichen amyloidosus
- Localized pruritus (e.g., only one arm affected)
- Neuropathic and psychogenic pruritus (notalgia paresthetica, brachioradial pruritus, somatoform prurigo, dilusional parasitosis, depression associated prurigo)
- Active dermatoses needing immediate therapy such as atopic dermatitis (without PN) or bullous pemphigoid;
- Have a history of use (within the specified time periods) of the medications listed below. Prior to randomization, a subject who used any of these medications must undergo a washout period equal to the length of the interval specified below (eg, 2 weeks for antihistamines, 4 weeks for naltrexone, and 4 weeks for cyclosporine A).
- Topical or systemic antihistamines, (used ≤2 weeks prior to the baseline visit) \[loratindine, or cetirizine may act as rescue medication during treatment\];
- Topical calcineurin inhibitors, topical capsaicin, menthol, camphor, polidocanol, topical antibiotics, antiseptic baths and cleansing lotions (used ≤2 weeks prior to the baseline visit);
- Topical steroids (used ≤2 weeks prior to the baseline visit);
- Naltrexone, paroxetine, fluvoxamine, amitriptyline, gabapentin, pregabalin, or UVtherapy (prescribed for the pruritus treatment) (used ≤4 weeks prior to the baseline visit);
- Systemic steroids (used ≤4 weeks prior to the baseline visit);
- Cyclosporine A and other immunosuppressants (used ≤4 weeks prior to the baseline visit).
- Have any medical condition or disability that would interfere with the assessment of safety or efficacy in this trial or would compromise the ability of the subject to undergo study procedures or to give informed consent.
