Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Part I In Part I of the study, 4 subjects per cohort will first receive a 30 minutes iv infusion of placebo followed by a 1 hour iv infusion of PDNO in parallel with a continuous infusion of a sodium bicarbonate carrier buffer. A total of 7 sequential cohorts with the following tentative dose levels are planned: 0.3, 1.0, 3.0, 10, 30, 60 and 120 nmol/kg/min. Up to 2 additional dose levels can be explored, tentatively 180 and 240 nmol/kg/min. Lower, intermediate doses (e.g. 90 nmol/kg/min) or repeated doses may also be given, based on the safety and tolerability of the drug if recommended by the iSRC. The maximum dose in the study will not exceed 240 nmol/kg/min.Subjects will come for 4 visits to the clinic. Screening (Visit 1) will take place from Day -28 to Day -1 and will include the subjects' signing of the informed consent and an eligibility check. At Visit 2, subjects will be admitted to the clinic on Day -1 for pre-dose assessments. The subjects will be carefully monitored by clinical staff during and after infusion. Vital signs (including pulse oximetry) and ECG will be checked at regular intervals. During the infusion, blood pressure will be continuously controlled via intra-arterial blood pressure monitoring. In all cohorts, safety, tolerability and PD exposure will be assessed before, during and after the PDNO iv infusion. FeNO monitoring will be also be performed. Part II Part II of the study will explore ascending doses of PDNO in 2 cohorts. In each cohort, 4 subjects will first receive a 30 minutes iv infusion of placebo followed by iv infusions of PDNO in 3 ascending doses in parallel with a continuous infusion of a sodium bicarbonate carrier buffer. Each of the first 2 dose levels in each cohort will be iv infused for 30 minutes whereas the highest dose level will be iv infused for 3 hours. To avoid any potential rebound effect, there will be no stabilisation period between either dose escalation. The planned dose levels are: 1, 3 and 10 nmol/kg/min in cohort 1 and 30, 60 and 120 nmol/kg/min in cohort 2. The actual doses given in Part II will be based on emerging knowledge of safety and tolerability of PDNO observed in Part I of the study. The maximum dose in Part II will not exceed the highest dose given in Part
- I. One additional cohort with additional doses or dosing schemes to establish the target dose for subsequent studies can be explored based on the safety and tolerability of the drug if recommended by the iSRC.
Experimental: The experimental arm PDNO in increasing doses
The Investigational medicinal product, PDNO is given intravenously, in part 2 the doses is increased twice.
Placebo Comparator: Placebo
The placebo comparator, NaCl is given intravenously, before the PDNO is given.
Drug: - PDNO
