Title: A Controlled Comparative Study of the Efficacy of SARNA Sensitive Lotion for Treatment of Uremic Pruritus in Adult Hemodialysis Patients
Brief Summary: The purpose of this research study is to evaluate the efficacy of SARNA Sensitive Lotion in the treatment of uremic pruritus in adult hemodialysis patients in a double-blind Controlled comparative trial.


Options:
A: Key Inclusion Criteria:

To be eligible for inclusion into the Double-blind Phase of the study, a patient must meet the following criteria:

* Has end-stage renal disease (ESRD) and has been on hemodialysis 3 times per week for at least 3 months prior to the start of screening;
* Has at least 2 single-pool Kt/V measurements ≥1.2, or at least 2 urea reduction ratio measurements ≥65%, or 1 single pool Kt/V measurement ≥1.2 and 1 urea reduction ratio measurement ≥65% on different dialysis days during the 3 months period prior to screening;
* Prior to randomization:

  * Has completed Worst Itching Intensity NRS worksheets up to 8 days prior to 1st dose;
  * Has a mean baseline Worst Itching Intensity NRS indicative of moderate to severe uremic pruritus.
* To be eligible for inclusion into the Open-label Extension Phase of the study, each patient will have to fulfill the additional key following criteria at the time of entry into the Open-label Extension Phase:

  * Has received at least 30 doses of the planned 36 doses of study drug during the Double-blind Phase of this study;
  * Continues to meet inclusion criteria.

Key Exclusion Criteria:

A patient will be excluded from the Double-blind Phase of the study if any of the following criteria are met:

* Known noncompliance with dialysis treatment that in the opinion of the investigator would impede completion or validity of the study;
* Scheduled to receive a kidney transplant during the study;
* New or change of treatment received for itch including antihistamines and corticosteroids (oral, IV, or topical) within 14 days prior to screening;
* Received another investigational drug within 30 days prior to the start of screening or is planning to participate in another clinical study while enrolled in this study;
* Has pruritus only during the dialysis session (by patient report);
* Is receiving ongoing ultraviolet B and anticipates receiving such treatment during the study;
* Participated in a previous clinical study with CR845.
* A patient will be excluded from the Open-label Extension Phase of the study if any of the additional key following criteria are met at the time of entry into the Open-label Extension Phase:

  * Completed the Double-blind Phase of this study but exhibited adverse events during the course of the Treatment Period that may preclude continued exposure to the study drug;
  * Was noncompliant with protocol procedures during the Double-blind Phase of this study which is indicative of an inability to follow protocol procedures.
B: Inclusion Criteria:

* Male or female patients 18 years of age to 70 years of age.
* A diagnosis of moderate to severe pruritus.
* At least 3 episodes of itch over a period of 2 weeks, each lasting for 2 minutes or more.
* Symptoms of itch in regular pattern over 6 months.
* Itch Visual analog scale (VAS) of 3cm or more out of 10 cm.
* All subjects will be end stage renal failure patients undergoing hemodialysis for at least 3 months, who have substantial pruritus for more than 6 months. Substantial pruritus is defined as persistent pruritus impairing sleep or daytime activity.
* Ability and willingness to follow all study procedures, attend all scheduled visits, and successfully complete the study
* The ability to understand and sign a written informed consent form, which must be obtained prior to treatment.

Exclusion Criteria:

* Presence of infection (as defined by the investigator) on the area to be treated.
* Subjects with history of pruritus predating renal failure and subjects with skin disease unrelated to uremia, such as atopic dermatitis, will be excluded.
* Use of systemic medications for treatment of pruritus including corticosteroids within the past 4 weeks and during the study.
* Use of topical medications for treatment of pruritus, including corticosteroids, within the past week.
* Pregnant women, women who are breast feeding, or women of child bearing potential who are not practicing an acceptable method of birth control (abstinence, birth control pill/patch, barrier with spermicidal jelly, IUD, etc.), as determined by the investigator. Acceptable contraception must be used during the entire study.
