Plain-language summary
This is a first-in-human, single-blind, placebo-controlled, single-centre study designed to assess the safety and tolerability of PDNO in healthy male and female subjects. In addition, the exposure of 1,2 propanediol (PD) will be evaluated.
There are 2 parts to the study:
Part I: single ascending dose (SAD), 7 cohorts, 30 minutes intravenous (i.v.) infusion of placebo followed by 1-hour i.v. infusion of PDNO to assess safety, tolerability and PD exposure in healthy male and female subjects.
Part II: ascending doses of PDNO in 2 cohorts, 30 minutes i.v. infusion of placebo followed by 3 ascending doses of PDNO in cohort 1 and 3 ascending doses of PDNO in cohort 2. The first 2 doses in each cohort will be i.v. infused for 30 minutes whereas the last will be i.v. infused for 3 hours to assess safety, tolerability and PD exposure in healthy male and female subjects.
If indicated by emerging data and recommended by the internal safety review committee (iSRC), 2 additional dose groups/cohorts (4+4 subjects) may be added to Part I and 1 dose group/cohort (4 subjects) may be added to Part II.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Willing and able to give written informed consent for participation in the study
* Healthy male and female subjects aged 18 to 45 years inclusive at screening
* Body Mass Index (BMI) ≥ 18.5 and ≤ 30.0 kg/m\^2 at screening
* Clinically normal medical history, physical findings, ECG and laboratory values
* Male subjects and women of non-childbearing potential may be included in the study. Male subjects must be willing to use condom or be vasectomised or practice sexual abstinence to prevent pregnancy and drug exposure of a female partner and refrain from donating sperm from the date of dosing until 3 months after dosing with the IMP. Their female partner of child-bearing potential must use contraceptive methods.
* Women of non-childbearing potential are defined as pre-menopausal females who are sterilised or postmenopausal
Exclusion Criteria:
* History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, might interfere with the drug absorption, distribution, metabolism or excretion of the drug or influence the results or the subject's ability to participate in the study
* Any clinically significant illness, medical/surgical procedure or trauma within 4 weeks of the first administration of IMP
* Malignancy within the past 5 years
* Any planned major surgery within the duration of the study
* Any positive result on screening for serum hepatit…
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?

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Safety and tolerability of PDNO following i.v. infusion to healthy volunteers, as measured by incidence of treatment-emergent AEs, SAEs, AESI, changes in vital signs, ECG abnormalities, and laboratory abnormalities.
