What this trial studies

This is a multicenter, prospective, phase 4 observational program that follows patients from prescription through initiation, titration, and maintenance of ONAPGO with standard-of-care nursing support. Participants have an Enrollment Day, a Baseline Period that includes in-home education by a Clinical Nurse Navigator, a Dose Initiation/Titration/Optimization period, routine maintenance visits, and an End-of-Study or discontinuation visit. Data are collected according to usual clinical practice without investigational interventions beyond the prescribed ONAPGO product and support services. The goal is to describe real-world use patterns, tolerability, dosing, and patient experiences across participating U.S. centers.

Who should consider this trial

Good fit: Ideal candidates are people with Parkinson's disease who have received a prescription for ONAPGO, have opted into Clinical Nurse Navigator support, and can provide informed consent.

Not a fit: Patients who were not prescribed ONAPGO, who cannot receive ONAPGO due to hypersensitivity, or who require contraindicated medications (such as 5-HT3 antagonists) are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, the findings could help patients and clinicians understand real-world tolerability, dosing patterns, and support needs for ONAPGO, potentially improving symptom management and care coordination.

How similar studies have performed: Continuous subcutaneous apomorphine infusion as a treatment for motor fluctuations has prior clinical evidence of benefit, but prospective real-world observational data specifically for the ONAPGO formulation are limited.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

Participant has received a prescription for ONAPGO™ according to the standard of care.

Participant has opted into receiving support services from the Clinical Nurse Navigator (CNN), a registered nurse specially trained to work with persons with Parkinson's disease, as noted on the Prescription Enrollment Form.

The HCP/Investigator determines the participant is an appropriate study participant.

Participant is able and willing to provide informed consent (or informed assent form \[IAF\], as applicable) and signs the consent form on the Enrollment Day.

Exclusion Criteria:

Did not receive a prescription for ONAPGO™.

Prescribed ONAPGO™, but the HCP/Investigator determines the participant should not participate in this observational study.

Concomitant use of ONAPGO™ with 5-HT3 antagonists, including antiemetics (e.g., ondansetron, granisetron, dolasetron, palonosetron) or alosetron.

Known hypersensitivity to apomorphine or to excipients of ONAPGO™, including sulfite (e.g., sodium metabisulfite).
