- Objective: To explore if the occurrence and severity of subcutaneous (sc) nodules is influenced by the pharmaceutical formulation of apomorphine used for sc infusion in advanced Parkinson’s disease (PD).Background: Apomorphine infusion is an effective therapy in advanced PD, but a limitation is troublesome sc nodules. Various chemically non-identical apomorphine formulations are available. Anecdotal clinical experience has suggested that shifting from one of these (Apo-Go PumpFill; apoGPF) to another (Apomorphine PharmSwed; apoPS, developed in Sweden) may influence the occurrence and severity of sc nodules.Methods: In this multicenter open-label prospective observational study, 15 people with advanced PD (mean PD- duration, 13.4 years; median Hoehn & Yahr, IV) on apoGPF since a mean of 2.1 years and with troublesome sc nodules were switched to apoPS. Ongoing interventions to treat existing nodules (ultrasound, massage, Hirudoid cream) continued, and apomorphine as well as other drugs was managed according to clinical routines. Data were collected between May 2015 and March 2017; at baseline, at the time of switching (about 2 weeks later), and up to 1.7-4.2 (mean, 2.5) months post-switch follow-up. Primary outcomes were total nodule numbers, size (mm diameter for the 5 worst nodules), consistency (scored 0-3 for the 5 worst nodules), and associated skin changes (scored 0-4 for the 5 worst nodules) and pain (scored 0-5). Patients also rated their perceived PD severity and motor complications (UPDRS IV). Patient preferences 5-12 months post-switch (2-9 months after follow-up) were also recorded.Results: Apomorphine and L-dopa doses did not change over the observation period (P≥0.400). Baseline nodule numbers (7.4 vs. 4.6; P<0.003), size (92.9 vs. 54.1 mm; P=0.016), consistency (11 vs. 5; P=0.003), skin changes (3 vs. 1.5; P=0.205), and average pain (1 vs. 0; P=0.020) improved 11 weeks post-switch. Patient-reported PD severity (P=0.020) and motor fluctuations improved (P=0.051), whereas dyskinesias tended to increase (P=0.205). At 5-12 months post-switch, 13 patients had decided to remain on apoPS; mainly due to improved nodules.Conclusions: These observations suggest that apoPS may have a better safety profile compared to apoGPF in terms of sc nodule occurrence and severity. There is a need for larger, randomized controlled studies for firmer conclusions.

Tidskriftsartikel (refereegranskat)abstract
- Continuous subcutaneous (s.c.) apomorphine infusion is an effective therapy for Parkinson's disease (PD), but a limitation is the formation of troublesome s.c. nodules. Various chemically non-identical apomorphine formulations are available. Anecdotal experiences have suggested that shifting from one of these (Apo-Go PumpFill®; apoGPF) to another (Apomorphine PharmSwed®; apoPS) may influence the occurrence and severity of s.c. nodules. We, therefore, followed 15 people with advanced PD (median PD-duration, 15 years; median "off"-phase Hoehn and Yahr, IV) on apoGPF and with troublesome s.c. nodules who were switched to apoPS. Data were collected at baseline, at the time of switching, and at a median of 1, 2.5, and 7.3 months post-switch. Total nodule numbers (P < 0.001), size (P < 0.001), consistency (P < 0.001), skin changes (P = 0.058), and pain (P ≤ 0.032) improved over the observation period. PD severity and dyskinesias tended to improve and increase, respectively. Apomorphine doses were stable, but levodopa doses increased by 100 mg/day. Patient-reported apomorphine efficacy tended to increase and all participants remained on apoPS throughout the observation period; with the main patient-reported reason being improved nodules. These observations suggest that patients with s.c. nodules caused by apoGPF may benefit from switching to apoPS in terms of s.c. nodule occurrence and severity. Alternatively, observed benefits may have been due to the switch itself. As nodule formation is a limiting factor in apomorphine treatment, a controlled prospective study comparing local tolerance with different formulations is warranted.
