Nalmefene in alcohol‐dependent patients with a high drinking risk: Randomized controlled trial

AIMS: Reducing alcohol consumption is one treatment approach for alcohol‐dependent patients. This study compared nalmefene 20 mg and 10 mg with placebo, combined with psychosocial support, in alcohol‐dependent Japanese patients with a high or very high drinking risk level (DRL).

Sumario:AIMS: Reducing alcohol consumption is one treatment approach for alcohol‐dependent patients. This study compared nalmefene 20 mg and 10 mg with placebo, combined with psychosocial support, in alcohol‐dependent Japanese patients with a high or very high drinking risk level (DRL). METHODS: This was a multicenter, randomized, double‐blind, phase 3 study conducted in alcohol‐dependent patients with a high or very high DRL. Patients were randomized to 24 weeks of treatment with as‐needed nalmefene 20 mg, 10 mg, or placebo with psychosocial support. The primary endpoint was change in heavy drinking days (HDD) from baseline to week 12. A key secondary endpoint was the change in total alcohol consumption (TAC) from baseline to week 12. RESULTS: At week 12, 234, 206, and 154 patients who received placebo, nalmefene 20 mg, and 10 mg were included in the primary endpoint analysis. Compared with placebo, nalmefene was associated with significant reductions in HDD at week 12 (difference in 20 mg group, −4.34 days/month; 95% confidence interval [CI]: −6.05 to −2.62; P < 0.0001; difference in 10 mg group, −4.18 days/month; 95%CI: −6.05 to −2.32; P < 0.0001), as well as a significant reduction in TAC at week 12 (P < 0.0001). The incidence of treatment‐emergent adverse events was 87.9%, 84.8%, and 79.2% in the groups receiving nalmefene 20 mg, 10 mg, and placebo, respectively. These events were mostly of mild or moderate severity. CONCLUSIONS: Nalmefene 20 mg or 10 mg effectively reduced alcohol consumption and was well tolerated in alcohol‐dependent patients with a high or very high DRL.
