Quality of Life Effects of Continuous Subcutaneous Infusion of Foslevodopa/Foscarbidopa in People with Parkinson's
Movement Disorders
P9 - Poster Session 9 (8:00 AM-9:00 AM)
3-003
To determine the effect of continuous subcutaneous infusion (CSCI) of foslevodopa/foscarbidopa (LDp/CDp) for 24-hours/day for 12 weeks on people with Parkinson’s (PwP) quality of life measured via Parkinson’s Disease Questionnaire-39 (PDQ-39) subdomains.
A prior 52-week open-label LDp/CDp CSCI phase 3 trial (NCT03781167) demonstrated significant improvement in the PDQ-39 subdomains of Activities of Daily Living (ADLs), Mobility, Bodily Discomfort (BD), Stigma, and the Summary Index. In a 12-week double-blind phase 3 trial comparing LDp/CDp CSCI and oral levodopa-carbidopa immediate-release (LD/CD-IR) tablets (NCT04380142), numerical PDQ-39 Summary Index improvements were observed in LDp/CDp- versus oral-treated patients. However, the hierarchical testing procedure utilized prevented claiming statistical significance by stopping at a higher-ranked endpoint, despite nominal P values observed at <.05.
This post hoc study analyzes the PDQ-39 subdomain results from the above-mentioned 12-week trial. PDQ-39 subdomain change from baseline to final were analyzed both within and between treatment groups. P values are nominal and not corrected for multiplicity.
Compared to the oral LD/CD-IR arm (n=59), LDp/CDp CSCI treatment (n=45) led to improvements in the PDQ-39 subdomains of Mobility (LS mean of difference [SE]: -6.70 [3.09]*) and Stigma (-5.28 [2.61]*) with the nominal P value of *≤.05. Significant within-group improvements were seen in oral-treated patients for the PDQ-39 Social Support subdomain (mean [SD]: 3.55 [10.53]*, n=47); and in LDp/CDp-treated patients (n=45) for subdomains of Mobility (-8.00 [18.19]**), ADLs (-8.98 [21.36]**), Stigma (-9.03 [20.58]**), and BD (-6.67 [18.51]*) at *P≤.05 or **P≤.01. Soileau et al. reported the 12-week trial safety was generally consistent with other levodopa-containing medicines and subcutaneous therapies.
This post hoc analysis shows improvements in Mobility and Stigma versus the oral arm with a nominal P value of ≤.05. And, the statistically significant within-group improvements versus baseline in four PDQ-39 subdomains of LDp/CDp-treated patients are consistent with the 52-week open-label trial results.
