Outcomes
Primary outcome [1] 328357 0
Safety and tolerability of RECCE®327 administered as a 1-hour intravenous infusion in healthy male subjects. Safety assessments will include the nature, frequency and severity of adverse events by treatment, laboratory safety parameters (serology, haematology, biochemistry, and urinalysis), blood pressure, and other vital signs (heart rate, respiration, and temperature), physical examination, and 12 lead electrocardiogram (ECG). Continuous cardiac telemetry will be used to monitor cardiac function.
Timepoint [1] 328357 0
Safety evaluations will be collected from the time of screening through completion of the end-of-study visit, or until all safety evaluations return to baseline or are considered stable and not requiring further follow up.

Adverse events as documented in the medical record will be collected from Screening through completion of the end-of-study visit, or until all safety evaluations return to baseline or are considered stable and not requiring further follow up.

A 12-lead ECG will be obtained from each subject at Screening, at check-in on Day -1, at Baseline (predose) and at 1, 2 and 4 hours postdose on Day 1, and at 24 hours on Day 2, and at the Day 7 EOS visit.

Vital signs will be measured with subject in supine position (for at least 5 minutes) at Screening, Check-in on Day -1, and Baseline (within 30 minutes prior to dosing). Additionally, blood pressure and heart rate measurements will be obtained at the following times:
Day 1: every 15 minutes (± 5 minutes) for the first 2 hours postdose, then every 30 minutes (± 5 minutes) from 2 to 6 hours postdose, then at 8 and 12 hours postdose (±10 minutes); Day 2: 24 hours (±10 minutes) postdose; and Day 7 (EOS visit).

Physical examination will be performed at Screening, Day-1 prior to dosing, Day 2, and Day 7 (EOS visit).

Clinical laboratory samples will be collected at Screening, Day -1 prior to dosing, Day 2, and Day 7 (EOS visit).

Cardiac telemetry will be performed on Day 1, from 1 hour predose to 7 hours post beginning of infusion.

Local infusion site pain and tolerability plus study staff assessment of the infusion site will be assessed using a visual pain scale and standardized template for marking the infusion site, at the following times postdose: 0.25, 0.5 and 1 hour (± 5 minutes), and 12 and 24 hours (± 15 minutes).
Secondary outcome [1] 398702 0
Pharmacokinetics (PKs) of RECCE327 administered as a 1-hour intravenous infusion in healthy male subjects.

The following individual PK parameters will computed: maximum plasma concentration (Cmax), time to Cmax, elimination rate constant, half-life, adjusted r2, AUC from dosing to infinity, AUC from time of dosing to last measurable concentration, percentage of area under the curve extrapolated beyond the last quantifiable plasma concentration, total body clearance, volume of distribution at steady state, mean residence time.

The following PK parameters will be determined for urine:
• Cumulative amount of drug excreted (Ae)
• Fraction of dose eliminated in urine (Furine)
• Urinary clearance
Timepoint [1] 398702 0
PK assessments will be obtained from all subjects who received either study drug or placebo on Day 1 and Day 2.

PK analysis will be completed only on the active treatment subjects.

PK analysis of drug plasma concentrations: Predose (0 hour; within 30 minutes prior to start of infusion), and at 5, 10, 15, 20, 30, 45 and 60 minutes (immediately prior to end of infusion), 65, 70, 75 and 80 minutes, and 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose.

PK analysis of drug urine concentrations: Predose (-8 to 0 hour) and then at the following intervals postdose: 0-4, 4-8, 8-12, 12-24 hours

Summary
Brief summary
This is a Phase 1, single-center, randomized, placebo controlled, single dose, double blind, parallel, pioneer-group, first-in-human (FIH) study to assess the safety, tolerability, and pharmacokinetics of RECCE®327 when administered as a single dose via a 1-hour IV infusion. All subjects will receive pretreatment with the antihistamine compound, cetirizine (Zyrtec®). Eight dose cohorts will be studied . An initial dose of 50 mg or placebo will comprise the 1st cohort of 10 subjects. The study will consist of a Screening period (up to 28 days), followed by Baseline assessments (Day -1), an in-patient Study Treatment Period (Day 1 and Day 2), and follow-up visit to the clinic at Day 7 (End of Study [EOS]).

After fulfilling Screening requirements, all subjects will check into the clinic in the afternoon of Day –1 for Baseline assessments. Subjects will be randomized on Day -1 to the sequence of RECCE®327 or placebo. Subjects will remain under observation at the investigational site for the duration of the study, from admission on Day –1 until discharge from clinic on Day 2. All subjects will return on Day 7 for a follow-up visit, or sooner as the Investigator deems necessary.
