The CIBIS III trial compared bisoprolol first and enalapril first regimens.
CIBIS Investigators and Committees, A randomized trial of beta-blockade in heart failure.
In CIBIS II, 15% of the patients randomized to bisoprolol stopped taking it; (1) in COPERNICUS, the withdrawal rate from carvedilol was also 15%; (2) and in MERIT-HE 10% of patients taking metoprolol experienced an adverse event that led to drug withdrawal.

This is precisely the purpose of the CIBIS III trial, which aims to answer the question of whether initiation of CHF therapy with a beta-blocker is comparable (non-inferior) to the initiation of therapy with an ACE inhibitor.
However, the results are not inconsistent with those of other studies, specifically MERIT-HF and CIBIS II.
