Background:
The efficacy and safety of ABT-335 + statin combination therapy was demonstrated in three 12-week, controlled studies of patients with mixed dyslipidemia randomized to ABT-335 (135mg) + low or moderate dose rosuvastatin (R), simvastatin (S), or atorvastatin (A), or ABT-335 or statin monotherapy. A subsequent 52-week open label extension study evaluated the long-term safety and efficacy of ABT-335 combined with statins.
Methods:
Patients who completed 12 weeks of treatment in the 3 controlled studies were eligible to enroll in the 52-week extension study to receive ABT-335 + the moderate dose statin that was used in their initial study: R 20mg, S 40mg, or A 40mg. This was a pre-specified, integrated analysis of patients receiving ABT-335 + statin in the 12- and 52-week studies.
Results:
Of the 2715 randomized patients, 2316 completed the 12-week studies and 1911 enrolled in the extension study. A total of 2201 patients received at least 1 dose of ABT-335 + statin for a median duration of 364 days; 1139 patients were treated for ≥52 weeks. The incidence of adverse events (AEs) was similar across all 3 combination therapy groups (Table
). The most common AEs were headache, upper respiratory tract infection, nasopharyngitis, and back pain. Rhabdomyolysis was not reported in any group. Patients who were initially randomized to ABT-335 + statin and continued in the extension study (N=979) had sustained improvements in multiple lipids. After 12 and 52 weeks of treatment, combination therapy resulted in mean percent decreases in TG (−45.7% and −47.5%, respectively) and LDL-C (−32.2% and −37.8%), and increases in HDL-C (17.6% and 23.8%). Mean values at 12 and 52 weeks were: TG 141.2 and 136.3 mg/dL; LDL-C 101.6 and 93.5 mg/dL; and HDL-C 45.0 and 47.1 mg/dL, respectively.
Conclusions:
Long-term ABT-335 + statin combination therapy was generally well tolerated and resulted in comprehensive and sustained improvements in TG, HDL-C, and LDL-C in adults with mixed dyslipidemia.
