Roxadustat
is well tolerated and effective for treating anemia in patients on peritoneal
dialysis (PD) regardless of whether patients have received prior treatment with
erythropoiesis stimulating agents (ESAs), a recent study found.

Outcomes
included the maintenance rate of average hemoglobin (Hb) level within 10 to 12
g/dL at weeks 18 to 24; average Hb level at weeks 18 to 24; and cumulative
response rate at the end of treatment (Hb thresholds 10.0 g/dL or 10.5 g/dL, or
an Hb increase of 1.0 g/dL or higher).

In a
24-week phase 3, open-label trial, Tadao Akizawa, MD, PhD, of Showa University
School of Medicine in Tokyo, and colleagues enrolled 56 anemic patients on PD.
The group included 13 patients not previously treated with ESAs (ESA-naïve group)
and 43 who received prior ESA treatment (ESA-converted group). The
investigators randomly assigned patients in the ESA-naïve group to receive
roxadustat at a starting dose of 50 mg or 70 mg 3 times per week. Patients in
the ESA-converted group received 70 mg or 100 mg 3 times per week depending on
the prior ESA dose.

Maintenance
rates at weeks 18 to 24 were 92.3% and 74.4% in the ESA-naïve and ESA-converted
groups, respectively, Dr Akizawa’s team reported in Therapeutic Apheresis and Dialysis. Average Hb levels during weeks
18 to 24 were 11.05 and 10.93 g/dL in the ESA-naïve and ESA-converted groups,
respectively. The cumulative response rate was 100% in the ESA-naïve group.

Common treatment-emergency adverse events included nasopharyngitis and back pain.
