Outcomes
Primary outcome [1] 321918 0
Evaluate the safety and tolerability of escalating doses of LMR-123 administered as an intravenous injection in healthy subjects compared to placebo.
Timepoint [1] 321918 0
Physical examinations, AEs, vital signs, ECG and clinical laboratory assessments measured throughout the study from screening to End of Study visit to assess any significant changes from baseline results.

Evaluate Pharmacokinetics of LMR-123 (Cohorts 2-7) measuring: - Area under the serum LMR-123 concentration curve to the last measurable data point; - Area under the serum LMR-123 concentration curve extrapolated to infinity; - Peak serum concentration; - Time to peak serum concentration; - Elimination half-life; - Clearance; - Volume of distribution; - Individual estimate of the terminal elimination rate constant, calculated using log-linear regression of the terminal portions of the plasma concentration-versus-time curves; - Mean resistance time.
Timepoint [1] 376709 0

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Cohort 1 is open label so randomization is not applicable.
For Cohort 2-7, a computer-generated randomization schedule will be prepared by an unblinded statistician prior to the start of the study. At the time of randomization, the subject will be assigned a unique randomization number, which will be allocated sequentially based on the pre-determined randomization schedule, and according to their chronological order of inclusion in the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Statistical methods / analysis
The sample size for this study is up to 52 subjects, this includes 1 cohort of 4 subjects, and 6 cohorts of 8 subjects. The sample size for this study has been selected without performing a formal sample size calculation.
In general, data will be summarized using descriptive statistics (mean, median, standard deviation, minimum and maximum) for the continuous variables or frequency counts and percentages for the categorical variables, as appropriate to the type of data. Baseline will be defined as the last available, valid, non-missing assessment prior to dosing.
