Efficacy and safety of ABT-335 (fenofibric acid) in combination with rosuvastatin in patients with mixed dyslipidemia: a phase 3 study.
OBJECTIVE
To evaluate a new formulation of fenofibric acid (ABT-335) co-administered with 2 doses of rosuvastatin in patients with mixed dyslipidemia.


METHODS
In a phase 3, multicenter, randomized, double-blind, active-controlled study, a total of 1445 patients with LDL-C>or=130 mg/dL, TG>or=150 mg/dL, and HDL-C<40 mg/dL (<50 mg/dL for women) were randomized to either ABT-335 (135 mg), rosuvastatin (10, 20, or 40 mg), or ABT-335+rosuvastatin 10 or 20 mg, and treated for 12 weeks. The primary efficacy comparisons were mean percent change in HDL-C and TG (ABT-335+rosuvastatin vs. corresponding dose of rosuvastatin), and LDL-C (ABT-335+rosuvastatin vs. ABT-335).


RESULTS
Combination therapy with ABT-335+rosuvastatin 10 mg resulted in significantly (p<0.001) greater improvements in HDL-C (20.3% vs. 8.5%) and TG (-47.1% vs. -24.4%) compared to rosuvastatin 10 mg; and LDL-C (-37.2% vs. -6.5%) compared to ABT-335. Similarly, significantly (p<0.001) greater improvements were observed with ABT-335+rosuvastatin 20 mg in HDL-C (19.0% vs. 10.3%) and TG (-42.9% vs. -25.6%) compared to rosuvastatin 20 mg; and LDL-C (-38.8% vs. -6.5%) compared to ABT-335 monotherapy. Greater improvements in multiple secondary endpoints were noted with combination therapy compared to prespecified monotherapies. Both combination therapy doses were generally well tolerated, with a safety profile consistent with ABT-335 and rosuvastatin monotherapies. No rhabdomyolysis or unexpected hepatic, renal, or muscle safety signals were identified.


CONCLUSIONS
In patients with mixed dyslipidemia, combination therapy with ABT-335+rosuvastatin resulted in more effective control of multiple lipid parameters than either monotherapy alone, with a safety profile similar to both monotherapies. This combination may be an appropriate therapeutic option to treat mixed dyslipidemia.
