Abstract: Introduction: The clinical outcome of switching to levodopa-entacapone-carbidopa intestinal gel (LECIG) after failure of subcutaneous foslevodopa/foscarbidopa (fLD/fCD) is unknown. We analyze it in people with Parkinson’s disease (PwP) treated in Spain. Methods: Retrospective analysis of PwP who had previously received fLD/fCD but dropped out for different reasons and started before this LECIG in Spain up to 30 November 2025. Non-parametric tests were applied to evaluate the changes between the pre- (Vpre) and post-treatment (Vpost) (LECIG) periods. Results: Data about 14 patients (57.1% males; 66.6 ± 8.6 years old) from 12 hospitals out of a total of 15 who were treated with LECIG were included. The mean time with fLD/fCD was 98.6 ± 92.3 days, with 92.9% and 57.1% experiencing side effects and lack of response, respectively. Specifically, significant subcutaneous nodules were reported in up to 64.3% of the patients. LECIG was a direct switch from fLD/fCD in 35.7% of the patients. LECIG was well tolerated, with only one dropout due to complications related to dementia. Adverse events were reported in 28.6% and 35.7% of the patients in the optimization and final follow-up evaluation (mean follow-up of 233.7 ± 157.4 days) phases, respectively. From Vpre to Vpost, “Off” time was reduced in 2.9 ± 1.9 h (p = 0.002) and motor symptoms burden improved significantly (p = 0.013), whereas a trend of significance was found for non-motor symptoms burden (p = 0.050) and quality of life (p = 0.126). Conclusions: LECIG could be an alternative therapeutic option in PwP who failed fLD/fCD.
