Senicapoc (ICA-17043) is a blocker of Gardos channel, a calcium-activated potassium channel, in the red blood cell. Preclinical studies and studies in transgenic models of Sickle cell disease (SCD) show that inhibition of potassium efflux through the Gardos channel is associated with an increased haemoglobin level, decreased dense cells and decreased hemolysis. Senicapoc is well tolerated when administered to SCD patients and produces dose-dependent increases in hemoglobin and decreases in markers of hemolysis. Senicapoc exerts anti-fibrotic and anti-inflammatory activities. Senicapoc has previously been in Phase III and Phase II clinical trials for the treatment of SCD and asthma, respectively.

Sample Use Guides

In Vivo Use Guide

Patients with sickle cell disease received single doses of ICA-17043 (Senicapoc) -50 mg, 100 mg, and 150 mg. The mean area under the concentration-time curve from time zero extrapolated to infinity (AUC(0-infinity)) for ICA-17043 increased in a dose-related manner (11,827, 19,697, and 30,676 ng.hr/ml for 50, 100, and 150 mg, respectively). Overall mean half-life was 12.8 days. Mean peak plasma concentrations rose between the 50- and 100-mg dose levels but plateaued at 150 mg (59.1, 108.7, and 109.1 ng/ml, respectively).

Route of Administration: Oral

In Vitro Use Guide

Senicapoc (ICA-17043) inhibited red blood cells dehydration with an IC(50) of 30 +/- 20 nM.
