A First-in-Human Phase 1 Study of Plasmalogen Precursor PPI-1011 in Healthy Adult Volunteers to Assess Safety, Tolerability, and Pharmacokinetics

Plain-language summary
PPI-1011 is being developed as a docosahexaenoic acid (DHA) containing plasmalogen precursor with good long-term stability, specifically for the treatment of rhizomelic chondrodysplasia punctata (RCDP), which is an ultra rare type of peroxisomal biogenesis disorder (PBD). The goal of treatment with PPI-1011 is to increase the levels of plasmalogens within circulation and tissues, with the hope that this will normalize plasmalogen levels in the body and result in clinical improvement to patients. The present study is a first-in-human (FIH), phase 1, randomized, double-blind, placebo-controlled, dose-escalation study to assess the safety, tolerability and pharmacokinetics (PK) of single and multiple ascending doses of PPI-1011 administered orally to healthy subjects. The study consists of 5 planned single-dose cohorts (n = 8 per cohort, total randomized 6 active: 2 placebo) with sentinel design. Following a review of the safety and PK data by the safety review committee and submission to Health Canada the study will be expanded to include 2 planned multiple-dose cohorts (n = 8 per cohort, total randomized 6 active: 2 placebo).

Inclusion criteria

. Body mass index (BMI) that is within 18.5 - 30.0 kg/m2, inclusive, and subject weighs no more than 91.0 kg.
. Healthy, according to the medical history, ECG, vital signs, laboratory results and physical examination as determined by the PI/Sub-Investigator.
. Systolic blood pressure between 95-140 mmHg, inclusive, and diastolic blood pressure between 55-90 mmHg, inclusive, oxygen saturation level between 95% and 100%, inclusive, and heart rate between 55-100 bpm, inclusive, unless deemed otherwise by the PI/Sub-Investigator.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
