Public Summary Document
Product: Nebivolol hydrochloride, tablets,
titration pack containing 42 tablets 1.25mg and 14 tablets 5 mg,
1.25 mg, 5 mg and 10 mg (base), Nebilet®
Sponsor: CSL Limited
Date of PBAC Consideration: November
2009
1. Purpose of Application
The submission sought an Authority required (STREAMLINED) listing
for moderate to severe heart failure in a patient stabilised on
conventional therapy which must include an ACE inhibitor (if
tolerated).
2. Background
This drug had not previously been considered by the PBAC.
3. Registration Status
Nebivolol was TGA registered on 26 June 2009 for the treatment of
essential hypertension and stable chronic heart failure as an
adjunct to standard therapies in patients 70 years or older.
4. Listing Requested and PBAC’s View
Authority required (STREAMLINED)
Moderate to severe heart failure stabilised on conventional therapy
which must include an ACE inhibitor if tolerated.
NOTE: Nebivolol is indicated for the treatment of stable chronic
heart failure as an adjunct to standard therapies in patients 70
years or older.
For PBAC’s view see Recommendation and Reasons.
5. Clinical Place for the Proposed Therapy
Many patients with clinical heart failure require combination
therapy with an angiotensin converting enzyme (ACE) inhibitor, a
beta blocker and a diuretic.
Nebivolol would be an alternative beta-blocker treatment option for
heart failure patients aged 70 years and older.
6. Comparator
The submission nominated carvedilol, bisoprolol and metoprolol as
the main comparators, which was considered appropriate.
7. Clinical Trials
The submission presented three direct randomised trials,
Patrianakos 2005, Lombardo 2006, Marazzi 2007, comparing nebivolol
and carvedilol; two of which used half the recommended dose of
nebivolol (Patrianakos 2005, Lombardo 2006) and all used the
recommended dose of carvedilol. The outcomes of the direct
randomised trials were percentage increase in left ventricular
ejection fraction (LVEF) and the six minute walk test (6MWT), which
were considered to be surrogate outcomes.
The evidence for patient relevant clinical outcomes such as
hospitalisations and mortality was based on an indirect comparison
of six placebo-controlled trials, nebivolol, SENIORS; carvedilol,
COPERNICUS, Carvedilol US, Carvedilol ANZ; bisoprolol, CIBIS-II;
metoprolol, MERIT-HF. The baseline characteristics of patients in
the SENIORS trial differed to that of the baseline characteristics
of patients in the placebo-controlled trials for the carvedilol,
bisoprolol and metoprolol trials.
The submission further provided the results of a post-hoc subgroup
of patients from the SENIORS trial, referred to as SENIORS Subgroup
in which, the patient baseline characteristics appeared to be more
similar to those of the comparator trials. Although mean age
remained higher and the proportion of men was somewhat lower, the
LVEF function in the SENIORS Subgroup was similar to that of
participants in the Carvedilol ANZ, CIBIS-II and MERIT-HF
trials.

8. Results of Trials
The results of the surrogate outcomes of percentage increase in LVEF and the six minute
walk test from the direct randomised trials and the percentage increase in LVEF results
from SENIORS ECHO ≤35% and Carvedilol ANZ are shown below

d estimated by the submission
None of the direct randomised trials were designed as a non-inferiority trial. However,
Marazzi, 2007 identified a difference in change in left ventricular ejection fraction
(δLVEF) of 3% as clinically significant, consistent with previous studies comparing
the effect of carvedilol and metoprolol on LVEF in patients with CHF. It was noted
that in Marazzi (2007) a significant difference was observed in baseline LVEF between
the groups (p<0.001), but no significant difference was observed in baseline six minute
walk tests between the groups (p=0.718).
Both SENIORS ECHO and Carvedilol ANZ demonstrated that nebivolol and carvedilol, respectively,
were superior to placebo in increasing LVEF.
In regard to toxicity comparisons, it was noted that each of the beta-blockers was
associated with different adverse event profiles.
9. Clinical Claim
The submission claimed nebivolol to be non-inferior in terms of
comparative effectiveness and non-inferior in terms of comparative
safety over other beta blockers (carvedilol, bisoprolol and
metoprolol).
For PBAC’s view, see Recommendation and
Reasons.
10. Economic Analysis
The submission presented a cost minimisation analysis. The
equi-effective doses are estimated as nebivolol 7.59 mg and
carvedilol 37 mg, and by extension, bisoprolol 7.4 mg, metoprolol
138 mg. The estimates were based on the Marazzi (2007) trial. The
PBAC accepted this.
For PBAC’s view, see Recommendation and
Reasons.
11. Estimated PBS Usage and Financial Implications
The likely number of packs dispensed per year was estimated to be
more than 200,000 in Year 5. This estimation was considered to be
underestimated.
The financial savings per year to the PBS was estimated to be less
than $5 million in Year 5. This estimation was considered to be
overestimated.
12. Recommendation and Reasons
The PBAC recommended the Authority Required (STREAMLINED) PBS
listing of nebivolol for moderate to severe heart failure in a
patient stabilised on conventional therapy which must include an
ACE inhibitor or Angiotensin II receptor antagonist (if tolerated),
on a cost minimisation basis compared with carvedilol, bisoprolol
and metoprolol. The equi-effective doses are estimated as nebivolol
7.59mg and carvedilol 37mg, and by extension, bisoprolol 7.4mg,
metoprolol 138mg, based on the Marazzi (2007) trial.
Despite some concerns raised during the evaluation and by ESC that
nebivolol may be less effective than the comparators, the PBAC
accepted that nebivolol is no worse in terms of efficacy and safety
than its pharmacological analogues carvedilol, bisoprolol and
metoprolol. This was despite the fact that the claim of
non-inferiority in the Marazzi (2007) was based on surrogate
outcomes (change in LVEF, the six minute walk test and NYHA class
improvement). Bisoprolol and metoprolol were listed on a
cost-minimisation basis versus carvedilol based on final outcomes
(mortality and hospitalisations). However, the PBAC noted that
nebivolol is cheaper than the comparators and thus, on balance,
could be recommended for listing.
The PBAC noted that the submission requested the restriction to
include a NOTE stating “Nebivolol is indicated for the
treatment of stable chronic heart failure as an adjunct to standard
therapies in patients 70 years or older”, based on the TGA
approved indication. The PBAC considered that inclusion of such a
NOTE could lead to potentially inappropriate promotion of nebivolol
for older patients. Further, there was evidence in the submission
that nebivolol is effective in patients younger than 70 years of
age as well as over this age and this evidence may not have been
available at the time of registration. The PBAC requested that the
National Prescribing Service educate prescribers regarding these
concerns.
The PBAC also recommended that the views of the sponsors of the
listed beta-blockers be sought concerning the minor amendment to
the restrictions to include the use of Angiotensin II receptor
antagonists (as well as ACE-inhibitors) for consistency with the
recommendation for nebivolol.

13. Context for Decision
The PBAC helps decide whether and, if so, how medicines should be
subsidised in Australia. It considers submissions in this context.
A PBAC decision not to recommend listing or not to recommend
changing a listing does not represent a final PBAC view about the
merits of the medicine. A company can resubmit to the PBAC or seek
independent review of the PBAC decision.
