Hypoxia-inducible factor prolyl hydroxylase inhibitors stabilize levels of
hypoxia-inducible factor that upregulate transcription of multiple genes
associated with the response to hypoxia, including production of erythropoietin.
We conducted two phase 2a studies to explore the relationship between the dose of
the hypoxia-inducible factor-prolyl hydroxylase inhibitor GSK1278863 and
hemoglobin response in patients with anemia of CKD (baseline hemoglobin 8.5-11.0
g/dl) not undergoing dialysis and not receiving recombinant human erythropoietin
(nondialysis study) and in patients with anemia of CKD (baseline hemoglobin
9.5-12.0 g/dl) on hemodialysis and being treated with stable doses of recombinant
human erythropoietin (hemodialysis study). Participants were randomized 1:1:1:1
to a once-daily oral dose of GSK1278863 (0.5 mg, 2 mg, or 5 mg) or control
(placebo for the nondialysis study; continuing on recombinant human
erythropoietin for the hemodialysis study) for 4 weeks, with a 2-week follow-up.
In the nondialysis study, GSK1278863 produced dose-dependent effects on
hemoglobin, with the highest dose resulting in a mean increase of 1 g/dl at week
4. In the hemodialysis study, treatment with GSK1278863 in the 5-mg arm
maintained mean hemoglobin concentrations after the switch from recombinant human
erythropoietin, whereas mean hemoglobin decreased in the lower-dose arms. In both
studies, the effects on hemoglobin occurred with elevations in endogenous
erythropoietin within the range usually observed in the respective populations
and markedly lower than those in the recombinant human erythropoietin control arm
in the hemodialysis study, and without clinically significant elevations in
plasma vascular endothelial growth factor concentrations. GSK1278863 was
generally safe and well tolerated at the doses and duration studied. GSK1278863
may prove an effective alternative for managing anemia of CKD.
