MIRCERA Keeps Haemoglobin Levels Stable With Significantly Fewer Dose Changes Than With Other ESAs

Basel, Switzerland (ots/PRNewswire)

- Dose Adjustments Considered to be one of the Main Causes of
Haemoglobin Instability in Chronic Kidney Disease Patients      A new
analysis has shown that once-monthly Mircera(R) maintains stable
haemoglobin (Hb) levels in patients with chronic kidney disease (CKD)
with significantly fewer dose changes than more frequently
administered erythropoiesis-stimulating agents (ESAs).
The pooled analysis showed that patients receiving Mircera once a
month in the four maintenance studies needed 25% fewer dose changes
during the initial titration period, 44% fewer during the evaluation
phase and 36% fewer during the follow-up period(1), compared to the
commonly used agents, epoetin and darbepoetin alfa.
Dose changes (increasing or decreasing the amount of drug
required to maintain a stable Hb level) have been identified as one
of the major causes of Hb fluctuations and is clear evidence that
anaemia is not being effectively managed(2). It is important to keep
Hb levels stable since fluctuating outside of the target ranges
exposes patients to a greater risk of death or
hospitalization(3),(4),(5),(6)(7). Indeed, fluctuations have been
reported to be experienced in up to 80% of CKD patients on
shorter-acting ESAs,(8).
Professor Angel de Francisco, a leading nephrologist at Hospital
Marques de Valdecilla, Santander, Spain who presented the findings
said, "The data confirm that a simple and practical treatment like
Mircera given once a month maintains stable haemoglobin levels with
fewer dose changes than other drugs. This difference is important as
we aim now in anaemia management to keep haemoglobin in quite a tight
range and a drug that has few dose changes will minimize this risk of
moving out of these boundaries."
The data, presented at the 45th European Renal
Association-European Dialysis and Transplant Association (ERA-EDTA)
Congress in Stockholm, confirm that once-monthly Mircera offers not
only an effective treatment option but also one that can help to
simplify anaemia management(1).
Editor's Notes
About the analysis
  • Pooled data from four pivotal Phase III maintenance studies (MAXIMA, PROTOS, RUBRA and STRIATA) in patients with CKD on dialysis who received treatment with Mircera (once-monthly and twice a month) or a comparator ESA (epoetin or darbepoetin alfa, at their prescribed dose and administration intervals) were evaluated for frequency of dose changes.
  • 410 patients were treated with Mircera once-monthly and 740 with a comparator ESA for up to 52 weeks. The dose of Mircera and ESA comparator agents was adjusted to maintain patients' haemoglobin within plus or minus1 g/dL of baseline and between plus or minus10.0-13.5 g/dL.
  • The mean number of dose changes for Mircera once-monthly vs. comparator ESA:
  • Titration period (28 wk): Mircera 2.9 - comparator ESA 3.9
  • Evaluation period (8 wk): Mircera 0.5 - comparator ESA 0.9
  • Follow-up period (16 wk): Mircera 1.6 - comparator ESA 2.5
About Mircera
Mircera is the first continuous erythropoietin receptor activator
indicated for the treatment of symptomatic anaemia in chronic kidney
disease. It has a different receptor interaction and longer half-life
than other ESAs which allows for sustained and predictable anaemia
management(9),(10),(11). It is now approved in 46 countries including
the European Union, the USA, Norway and Switzerland. Mircera's method
of administration is simple: it is the only ESA approved in the EU to
correct anaemia with an immediate once-every-two-week treatment
schedule in all CKD patient types (those on or not on dialysis) with
either an IV or SC dose. CKD patients on dialysis or not, on any ESA,
can then be directly switched to a once-monthly maintenance schedule.
This ability to switch patients directly has the potential to
simplify anaemia management(12).
Simplifying anaemia management means physicians and nurses may be
able to focus their time and resources on managing the underlying
conditions that affect their patients such as high blood pressure,
high cholesterol, and diabetes. Modelling data presented at ERA-EDTA
last year showed that it may be possible to cut nearly in half the
annual time spent on anaemia management in a dialysis centre by using
a once-monthly anaemia agent(13).
For patients, less frequent dosing can mean a reduction in the
burden of avoidable office visits and as few as 12 injections a year.
This may be especially important for patients who are not on dialysis
and therefore have no need for frequent clinic visits.
