摘要

Background

Continuous subcutaneous infusion of levodopa/carbidopa (ND0612) is a promising alternative to oral therapy for Parkinson's disease. Motor fluctuations and "off time" significantly impact the quality of life in advanced diseases. This meta-analysis evaluates the effectiveness of ND0612 in reducing "off time," improving the overall quality of life, and enhancing sleep quality.

Method

A comprehensive search of 549 studies was performed, and five eligible studies (n = 327) were included after intense screening. The ROB2 tool and ROBINS1 were used to assess the quality of the included studies. The outcomes assessed included reductions in "off time" (hours), quality of life (PDQ-39 scores), and sleep quality (PDSS scores). Statistical heterogeneity was assessed using the I2 and tau2 statistics.

Results

The meta-analysis showed a significant reduction in OFF time for ND0612 compared to oral regimens, with a standardized mean difference (SMD) of -0.53 (95% CI: -0.76, -0.30), and compared to placebo with an SMD of -0.30 (95% CI: -1.05, 0.44). For improvement in quality of life, a favorable effect of ND0612 was shown compared to oral regimens (SMD = -0.31, 95% CI: -0.54, -0.08) and placebo (SMD = 0.44, 95% CI: 1.19, -0.32). Sleep quality (PDSS scores) demonstrated a slight improvement compared with oral regimens (SMD = -0.21, 95% CI: -0.44, 0.02) and a more significant improvement compared with placebo (SMD = -0.42, 95% CI: -0.87, 0.03). Overall, ND0612 provided consistent benefits in reducing OFF time and enhancing both quality of life and sleep in patients with Parkinson's disease.

Conclusion

ND0612 significantly reduced “off time” and improved quality of life among Parkinson’s disease patients experiencing motor fluctuations. However, its effect on sleep quality was inconsistent, with no clear, robust benefit demonstrated. Overall, this analysis supports ND0612 as an effective therapeutic option in patients with advanced Parkinson’s disease.
