Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Byvalson
Byvalson has been evaluated for safety in patients with hypertension. A total of 1,664 patients received at least 1 dose of a fixed-dose combination of nebivolol/valsartan in an 8-week trial. A total of 807 patients received at least 1 dose of nebivolol and valsartan in an open-label safety study; of these, 621 patients completed 180 days and 476 patients completed 360 days of open-label treatment with nebivolol and valsartan.
The safety of the 5 mg/ 80 mg dose of nebivolol/valsartan was evaluated during the first 4 weeks of an 8-week placebo-controlled trial. During the 4 week period, the overall incidence of adverse events on therapy with Byvalson 5 mg/ 80 mg was similar to placebo and the individual components (nebivolol 5 mg and valsartan 80 mg). Discontinuation of therapy due to a clinical adverse event occurred in 2.0% of patients treated with Byvalson 5 mg/ 80 mg versus 3.2% of patients given placebo and approximately 1% of patients given nebivolol 5 mg or valsartan 80 mg as monotherapy.
