About this trial

A study to evaluate the pharmacodynamic effects, safety, and tolerability of patiromer in children under 12 years of age with hyperkalaemia.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

- Paediatric participants (<12 years of age) with hyperkalaemia at screening.

- Participant's age should not reach 12 years during the 28 days of the pharmacodynamic/dose-ranging period.

- Participant is able to receive regular external feeding and medication, including via tubes, i.e., percutaneous endoscopic gastrostomy (PEG) or entero-gastric feeding tube.

- At screening/baseline, the results from 2 separate and consecutive potassium assessments using the same measurement method (whole blood, plasma, or serum) need to be above the age-appropriate upper limit of normal (ULN).

Disqualifiers

- Preterm birth infants with <37 weeks of gestation cannot be included in Cohort 3.

- Participants who due to their general condition, e.g., anaemia or low body weight, are not suitable to have blood volume withdrawn.

- Any of the following renal conditions: maintenance haemodialysis, renal artery stenosis, and acute kidney injury (defined by 2012 Kidney Disease Improving Global Outcomes) or a history of acute renal insufficiency in the past 3 months. Note: Chronic kidney disease (CKD) is not excluded.

- A history of or current diagnosis of a severe gastrointestinal (GI) diagnosis or surgery that could affect GI transit of the drug (delayed gastric emptying), such as a severe swallowing disorder, severe gastroesophageal reflux, uncorrected pyloric stenosis, intussusception, any other intestinal obstruction (e.g., Hirschsprung disease, chronic intestinal pseudo-obstruction, clinically significant postsurgical abdominal adhesions) or any gut-shortening surgical procedure prior to screening. Pre-gastric above-mentioned pathologies may be disregarded in case of existence of a PEG or entero-gastric feeding tube, as the PEG or entero-gastric feeding tube will serve for nutrition and investigational product administration.
