Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will be sequentially allocated to one of 2 dose cohorts:
• Cohort 1 will receive 0.75 mg/kg of PPS
• Cohort 2 will receive 1.5 mg/kg of PPS
All subjects will receive PPS through subcutaneous injection from Day 1 to Week 72 (i.e., 72 weeks on PPS therapy). For Weeks 1 through 12, dosing will be weekly. From Weeks 14 through 72, dosing will be every other week. Intervention will be administered by a suitably qualified member of the study team, either a nurse or a doctor. Adherence to therapy will be recorded by the study team members.
Intervention code [1] 317217 0
Treatment: Drugs
Comparator / control treatment
Safety and efficacy of both dose cohorts will be analysed as well as a comparison between the two cohorts.

0.75mg/kg will be the reference comparator
Control group
Dose comparison

Outcomes
Primary outcome [1] 323342 0
