This is a 2-part (phase 2b/3) prospective, interventional, multicenter, randomized, double-blind, placebo-controlled study. Part 1 (phase 2b) is a dose-finding study for CSL300 vs placebo. Part 2 (phase 3) aims to assess the efficacy of CSL300 on cardiovascular (CV) outcomes and safety in subjects with systemic inflammation and either atherosclerotic cardiovascular disease (ASCVD) or diabetes with end stage kidney disease (ESKD) undergoing maintenance dialysis.

The Parkinson's Progression Marker Initiative (PPMI) is an observational, international, multi-center study designed to identify PD progression biomarkers both to improve understanding of disease etiology and course and to provide the necessary tools to enhance the likelihood of success of therapeutics studies to slow PD progression (ClinicalTrials.gov Identifier: NCT01141023). A key focus of PPMI is to identify biomarkers during the period when PD neurodegeneration is already present, but symptoms of PD have not yet occurred. This prodromal cohort would enable us to investigate PD biomarker signatures prior to onset of typical symptoms of PD. The study is a longitudinal, multi-center study to assess progression of \[18F\]AV-133 imaging in Prodromal PD participants. The PPMI 015 study will enroll participants from the PPMI Clinical (002) study. Participants will be followed annually for up to 24 months. Approximately 100 Prodromal participants will be recruited from up to 10 sites. Participants will be comprehensively assessed at baseline and follow up. Participants will undergo \[18F\]AV-133 PET imaging targeting the vesicular monoamine transporter. All participants will undergo an initial \[18F\]AV-133 PET imaging scan at baseline with repeat imaging at 12 months and 24 months.

PPMI is a broad program, expanding the goals of the original PPMI study, that includes this PPMI Clinical protocol, as well as other program initiatives such as the PPMI Remote, PPMI Digital App and PPMI Online protocols. Participants in PPMI may be asked to be enrolled in other PPMI program protocols, but depending on their method of recruitment, participants may be enrolled sequentially in varying order, as appropriate. PPMI participants may also be asked to participate in additional PPMI program initiatives (as they are developed), which may only involve a subset of PPMI participants based on their cohort designation and/or site location.
