Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Cohort 1 - participants will receive a single subcutaneous(SC) dose of PPS at 2 mg/kg once weekly for a total of 6 weeks. Participants will visit the clinical trial centre once weekly for 6 weeks for treatment injections. Participants will remain confined until completion of the 24-hour post-dose assessments on Day 2 (Dose 1). For the remaining doses, participants will attend the CRU for pre-dose assessment, dosing, and post-dosing assessment as outpatients. Patients adherence to visits will be by reminder phone calls, emails and texts.

Cohort 2 - participants will receive a single subcutaneous(SC) dose of PPS at 2 mg/kg twice weekly for a total of 6 weeks. Participants will visit the clinical trial centre twice weekly for 6 weeks for treatment injections. Participants will remain confined until completion of the 24-hour post-dose assessments on Day 2 (dose 1). For the remaining doses, participants will attend the CRU for pre-dose assessment, dosing, and post-dosing assessment as outpatients.
Patients adherence to visits will be by reminder phone calls, emails and texts.

Outcomes
Primary outcome [1] 323332 0
To assess the pharmacokinetics (PK) of multiple SC doses of PPS in healthy adult participants

For Initial Dose
• Maximum observed concentration (Cmax)
• Time to maximum observed drug concentration (Tmax)
• AUC from time zero to the last measurable concentration (AUC0-last)
• AUC from time zero to infinity (AUC0-inf)
• Apparent terminal elimination rate constant (kel)
• Apparent elimination half life (t½)
• Apparent clearance (CL/F)
• Apparent terminal volume of distribution (Vz/F)
•
For repeated doses:
• Maximum plasma concentration during each dosing interval (Cmax).
• Time to maximum concentration (Tmax).
• Lowest concentration during each dosing interval (Cmin).
• Average concentration during each dosing interval (Cav).
• Concentration at the end of each dosing interval (Ctrough).
• Degree of fluctuation [(Cmax-Cmin)/Cav].
• Swing [(Cmax-Cmin)/Cmin].
• Areas under the plasma concentration-time curve during each dosing interval AUC0-last, and AUC0-inf, provided estimation of kel is possible.
• Apparent terminal elimination rate constant during each dosing interval, (kel) , provided estimation is possible
• Apparent clearance during each dosing interval (CL/F).
• Apparent terminal volume of distribution (Vz/F)
• Accumulation ratio (RA) during each dosing interval.
Timepoint [1] 323332 0
Cohort 1 -PK samples will be collected for Dose 1, 3, and 6, within 15 minutes prior to dosing and at 0.25, 0.5, 1, 1.5, 2, 3, 4, 8, 1 24, 36, and 48 hours post dose. For Dose 2, 4 and 5 PK samples are collected within 15 minutes pre-dose
Cohort 2 - PK samples will be collected for dose 1, 5 and 12 within 15 minutes prior to dosing and at 0.25, 0.5, 1, 1.5, 2, 3, 4, 8, 1 24, 36, and 48 hours post dose. For Dose 2, 3, 4, 6, 7, 8, 9, 10, 11 PK samples are collected within 15 minutes pre-dose
Secondary outcome [1] 381595 0
To assess the safety and tolerability of multiple SC doses of PPS in healthy adult participants..
Safety and tolerability will be assessed by adverse event assessment (eg. Injection site pain or bruising, ), vital signs (including ECG’s), physical exams and laboratory blood monitoring.
Timepoint [1] 381595 0
Cohort 1- Safety and tolerability will be assessed at every clinic visit on Days 1, 2, 3, 7, 12, 14, 15, 16, 21, 28, 35, 36, 37 and 42
Cohort 2 - Safety and tolerability will be assessed at every clinic visit and on Days 1, 2, 3, 4, 5, 7, 10, 14, 15, 16, 17, 21, 24, 28, 31, 35, 38, 39, 40, 45

Key exclusion criteria
History of severe allergic or anaphylactic reactions

Prior or ongoing medical conditions, medical history, physical findings, or laboratory abnormality that, in the Investigator’s (or delegate’s) opinion, could adversely affect the safety of the participant
Presence of any underlying physical or psychological medical condition that, in the opinion of the Investigator, would make it unlikely that the participant will comply with the protocol or complete the study per protocol
