Scientific title
An Open-label, Single Arm Study to Evaluate the Pharmacokinetics of a Single Dose of Intravenous Difelikefalin in Adolescents Aged 12 to 17 Years on Haemodialysis
Acronym
Brief summary of the study: English
This is an open-label study to evaluate the activity of a single dose of intravenous Difelikefalin in the body, including its absorption, distribution and excretion from the body, in adolescents aged 12 to 17 Years on haemodialysis.
Brief summary of the study: Arabic
هذه دراسة مفتوحة التسمية لتقييم نشاط جرعة واحدة من Difelikefalin عن طريق الوريد في الجسم ، بما في ذلك امتصاصه، توزيعه وإفرازه من الجسم ، لدى المراهقين الذين تتراوح أعمارهم بين 12 و 17 عامًا يخضعون لغسيل الكلى.
Health conditions/problem studied: Specify
Patients with chronic kidney disease undergoing hemodialysis
Interventions: Specify
Drug: Difelikefalin (CR845)
Key inclusion and exclusion criteria: Inclusion criteria
1. End-stage renal disease (ESRD) subjects who have been on HD for at least 3 months and are currently on HD at least 3 times per week. Subjects with or without associated pruritus may enroll. 2. Males or females 12 to 17 years of age, at the time of consent. 3. Has a prescription dry body weight ≥20 kg and ≤100 kg.
Key inclusion and exclusion criteria: Gender
Both
Key inclusion and exclusion criteria: Age minimum
12
Key inclusion and exclusion criteria: Age maximum
17
Key inclusion and exclusion criteria: Exclusion criteria
1. Known to be non-compliant with HD treatments and deemed unlikely to complete the study by the Investigator (i.e., has a history of missed HD sessions due to non-adherence in the past 2 months). 2. Planned or anticipated to receive a kidney transplant during the study. Note: Being on a kidney transplant list is not an exclusion criterion. 3. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) greater than 2.5 × the reference upper limit of normal (ULN), or bilirubin greater than 4 × the ULN at screening. 4. Subject has known hypersensitivity to the study drug or any components of the difelikefalin formulation. 5. Known history of allergic reaction to opiates such as hives. Note: Side effects related to the use of opioids such as constipation or nausea would not exclude the subjects from the study. 6. Previous participation in this study. 7. Known or suspected history of alcohol, narcotic, or other drug abuse or substance dependence within 12 months prior to screening. 8. Acute or unstable medical condition(s) which in the opinion of the Investigator would pose undue risk to the subject or would impede complete collection of evaluable data.

Pharmaceutical class
Selective Kappa-Opioid Receptor (KOR) full agonist
Therapeutic indication
moderate-to-severe pruritus associated with chronic kidney disease in patients on haemodialysis
Therapeutic benefit
Opioid receptors are involved in the modulation of pruritus and pain signals and consist mainly of 3 subtypes, classified as mu, kappa, and delta. These receptor subtypes are found in the CNS (ie, brain and spinal cord), on sensory ganglionic neurons and their nerve fibers innervating peripheral tissues such as skin, and on certain cell types of the immune system. Most clinically used opioid analgesics act primarily via activation of mu-opioid receptors located in the CNS and peripheral nervous system. As such, there are associated with a wide array of side effects, such as sedation, respiratory depression, abuse liability, cardiovascular collapse, and death. To avoid these undesirable effects, difelikefalin was designed to only activate KORs, which are known to modulate visceral and inflammatory pain, pruritus, and inflammatory signals in animals and humans.
