Consider PRODUODOPA for the treatment of advanced levodopa-responsive Parkinson’s disease with severe motor fluctuations and hyperkinesia or dyskinesia when available combinations of Parkinson’s medicinal products have not given satisfactory results1,2

12-week study: Efficacy and safety study3

A pivotal, Phase 3, randomised, double-blind, double-dummy, active-controlled study evaluating the efficacy, safety and tolerability of 24- hour daily continuous subcutaneous infusion of PRODUODOPA (n=74) compared with oral IR levodopa/carbidopa (n=67) for the treatment of motor fluctuations in patients with advanced PD (N=141) at 12 weeks.3

  • Of the 74 patients randomised to receive PRODUODOPA, 48 completed the study and 26 discontinued treatment
  • Of the 67 patients receiving optimised oral IR levodopa/carbidopa (LD/CD), 62 completed treatment and 5 discontinued
  • Primary reasons for drug discontinuation in both groups were adverse events, withdrawn consent, and difficulty with the drug delivery system. The incidence of adverse events leading to study drug discontinuation was higher in the PRODUODOPA group with infusion site adverse events (cellulitis 4/74 [5%]), pain (3/74 [4%]), bruising, haemmorrhage and oedema (2/74 [3%]) being most common3

Change from baseline to Week 12 in average daily normalised ‘On’ time without troublesome dyskinesia was the primary endpoint. ‘On’ time without troublesome dyskinesia is the sum of normalised ‘On’ time without dyskinesia and normalised ‘On’ time with non-troublesome dyskinesia.3

Key secondary endpoints included change from baseline to Week 12 in average daily normalised ‘Off’ time, Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Part II score and presence of morning akinesia at Week 12. Morning akinesia is defined as reporting ‘Off’ status as the first morning symptom on waking.3

  • Secondary efficacy endpoints were tested in a hierarchical order3
  • Hierarchical testing for significance was terminated at the first secondary endpoint, change in MDS-UPDRS Part II, as this did not reach statistical significance3
  • As the secondary endpoints following MDS-UPDRS Part II weren’t tested for significance, no p values are available in the referenced publication3 and no clinical conclusions can be drawn from these endpoints

‘On’ and ‘Off’ times and morning akinesia were assessed using a 24-hour Parkinson’s disease diary and normalised to a 16-hour waking day.3

In a study, PRODUODOPA provided a significant improvement (increase) in average daily normalised ‘On’ time without troublesome dyskinesia and a significant reduction (decrease) in average daily normalised ‘Off’ time vs oral IR LD/CD at 12 weeks3

Average daily normalised ‘On’ time without troublesome dyskinesia and normalised ‘Off’ time at 12 weeks3

‘On’ time without troublesome dyskinesia is the sum of normalised ‘On’ time without dyskinesia and normalised ‘On’ time with non-troublesome dyskinesia. Assessed using a 24-hour PD Diary and normalised to a 16-hour waking day. The mean daily normalised ‘On’ time without troublesome dyskinesia for patients on PRODUODOPA was 9.20 hours (SE 2.42) at baseline and 9.49 hours (SE 2.62) for patients taking optimised oral IR LD/CD. The mean daily normalised ‘Off’ time for patients on PRODUODOPA was 6.34 hours (SE 2.27) at baseline and 5.91 hours (SE 1.88) for patients taking optimised oral IR LD/CD.

Adverse events (AEs) were reported in 63 (85%) of 74 patients treated with PRODUODOPA and 42 (63%) of 67 patients treated with oral IR LD/CD at Week 123

52-week study: Safety study4

A Phase 3, single-arm, open-label study evaluating the safety, tolerability, and efficacy of 24-hour daily exposure with a continuous subcutaneous infusion of PRODUODOPA in patients with advanced PD (N=244) at 52 weeks. Of 244 enrolled patients, 107 (44%) discontinued treatment and 137 completed treatment with PRODUODOPA.4

Safety and tolerability were the primary endpoints. The proportion of patients reporting adverse events, changes in laboratory parameters, vital sign measurements, and electrocardiogram values from baseline. Local skin tolerability was additionally assessed by the Infusion Site evaluation scale.4

Secondary endpoints included change from baseline in the average daily normalised ‘Off’ time and ‘On’ time as assessed by the PD diary and normalised to a 16-hour waking day, MDS-UPDRS Parts I-IV (with Part III measured in the patient’s best on state), Parkinson’s Disease Sleep Scale-2 (PDSS-2), 39-Item Parkinson’s Disease Questionnaire (PDQ-39), EuroQol 5-Dimension Questionnaire (EQ-5D-5L) and the proportion of patients with morning akinesia. Morning akinesia was defined as reporting ‘Off’ status in PD diary as the predominant PD status during the first half-hour period upon awakening.4

The safety analysis set included all patients who received at least one infusion of PRODUODOPA at any given time during the study. Efficacy was assessed in the full analysis set.

*While the values for severe AEs and serious AEs were the same, the patients reporting these events were not the same for each event. There were a total of five deaths in the safety population; two were non-treatment-emergent (did not occur during study treatment or within 30 days of the last PRODUODOPA infusion); all were determined by investigators to be unrelated to the study drug. Treatment-emergent deaths include subdural hematoma (most likely related to traumatic injury from an accidental fall) and cerebral mass effect, cardiorespiratory arrest, and cerebrovascular accident.

Efficacy endponts4

Efficacy endpoints were summarised using descriptive statistics. P values throughout this study are nominal and therefore no clinical conclusions can be drawn from this data.4

Average daily normalised ‘Off’ time and ‘On’ time

The mean daily normalised ‘Off’ time for patients on PRODUODOPA was 5.9 hours (SD 2.2) at baseline. The mean daily normalised ‘On’ time without dyskinesia was 6.5 hours (SD 3.4) at baseline. The mean daily normalised ‘On’ time with non-troublesome dyskinesia was 2.6 hours (SD 2.6) at baseline. The mean daily normalised ‘On’ time with troublesome dyskinesia was 1.0 hours (SD 1.7) at baseline. The mean daily normalised ‘On’ time without troublesome dyskinesia was 9.1 hours (SD 2.5) at baseline.

Study design3

Duration: 12 weeks.

Study type: Pivotal, Phase 3, randomised, double-blind, double-dummy, active-controlled study conducted at 65 academic and community study centres in the USA and Australia.

Patient population: Patients aged at ≥30 years with a diagnosis of idiopathic and levodopa-responsive Parkinson’s disease (PD). Patients were required to be on a minimum of 400 mg/day levodopa equivalents (from levodopa-containing medications and catechol-O-methyl transferase (COMT) inhibitors), and have inadequately controlled motor fluctuations with an average off time of at least 2.5 hours/day over 3 consecutive days.

Aim: To assess the efficacy and safety of 24-hour/day continuous subcutaneous infusion of PRODUODOPA compared with oral immediate-release (IR) levodopa/carbidopa (LD/CD) for the treatment of motor fluctuations in patients with advanced Parkinson’s disease.

Methods: The study included a screening period (6–60 days), an oral LD/CD stabilisation period (2–3 weeks), and a double-blind treatment period (12 weeks) for a total of 13 scheduled visits. 141 patients were randomised 1:1 to either 24-hour/day CSCI of PROUDODOPA plus oral placebo or 24-hour/day CSCI of placebo solution plus oral LD/CD:

  • Of the 74 patients randomised to receive PRODUODOPA, 48 completed the study and 26 discontinued treatment (14 from adverse event, 5 withdrew consent, 1 from lack of efficacy, 4 had difficulty with drug delivery system and 2 others)
  • Of the 67 patients receiving optimised oral IR LD/CD, 62 completed treatment and 5 discontinued (1 from adverse event, 3 withdrew consent and 1 had difficulty with drug delivery system)
  • Primary reasons for drug discontinuation in both groups were adverse events, withdrawn consent, and difficulty with the drug delivery system. The incidence of adverse events leading to study drug discontinuation was higher in the PRODUODOPA group with infusion site adverse events (cellulitis 4/74 [5%]), pain (3/74 [4%]), bruising, haemmorrhage and oedema (2/74 [3%]) being most common

Study design4

Duration: 52 weeks.

Study type: 52-week, phase 3, open-label, single-arm, multicentre study conducted at 60 sites across 13 countries (Australia, Belgium, Canada, Denmark, Germany, Italy, Japan, Netherlands, Russia, Spain, Sweden, United Kingdom, and United States of America).

Patient population: Patients aged at ≥30 years with a diagnosis of idiopathic and levodopa-responsive Parkinson’s disease (PD). Before initiation of PRODUODOPA, patients must have had symptoms that, in the investigator’s opinion, were not adequately controlled by their current therapy, and must have experienced an average of ≥2.5 hours of ‘Off’ time per day, as assessed by the electronic PD diary over two consecutive days prior to day 1 (study enrollment).

Aim: To assess to assess the safety, tolerability, and efficacy of PRODUODOPA administered as a 24-hour/day continuous subcutaneous infusion (CSCI) in patients with PD whose motor symptoms were inadequately controlled by their current treatment.

Methods: Of the 244 patients treated with PRODUODOPA, 137 completed the study and 107 prematurely discontinued treatment with PRODUODOPA.
