An AE is any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
Hematology assessments will be performed for the following parameters: platelet count, red blood cell (RBC) count, hemoglobin, hematocrit, white blood cells (WBC) (absolute), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
Clinical chemistry assessments will be performed for the following parameters: blood urea nitrogen (BUN), creatinine, glucose, potassium, sodium, calcium, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, total and direct bilirubin, total protein, and albumin.
Dipstick method will be used to measure pH, glucose, protein, blood and ketones.
Three readings of blood pressure will be taken at screening (single readings at all other time-points).
Three readings of pulse rate will be taken at screening (single readings at all other time-points).
Absolute values and changes over time of heart rate from pre-dose values as a measure of safety and tolerability.
Triplicate 12-lead ECGs will be obtained screening and predose (predose IM oxytocin), and single 12-lead ECGs at all other time-points during the study using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals.
FEV1 is the volume exhaled during the first second of a forced expiratory maneuver started from the level of total lung capacity. Pulse oximetry is a procedure used to measure the oxygen level (or oxygen saturation) in the blood.
Blood samples will be withdrawn from subjects at pre dose, 3 minutes (mins), 5 mins, 10 mins, 20 mins, 0.5h, 0.75h, 1 hour (h), 1.5 h, 2 h, 2.5 h, 3 h, 4 h, 8 h, and 24 h (24 h post dose assessments only applicable to Dosing Session 1, Group 1 and the first 3 subjects at each new dose level \[Dosing Sessions 2 -4\]).
Blood samples will be withdrawn from subjects at pre dose, 3 mins, 5 mins, 10 mins, 20 mins, 0.5 h, 0.75 h, 1 h, 1.5 h, 2 h, 2.5 h, 3 h, 4 h, and 8 h.

Oxytocin is being studied for the prevention or treatment of postpartum hemorrhage, a condition of heavy bleeding after childbirth. It is currently in Phase 1 clinical development as an investigational therapy for this indication.
Oxytocin is being developed by GSK plc, a global biopharmaceutical company listed on the stock exchange under the ticker GSK.
Oxytocin is in Phase 1 clinical development. It has completed a Phase 1 trial, and it remains an investigational drug that has not been approved for any use.
Oxytocin has one completed clinical trial, NCT02542813, which was a Phase 1 study evaluating the safety, tolerability, and pharmacokinetics of an inhaled formulation in healthy female volunteers. The trial enrolled 16 participants in the United Kingdom.
In the completed Phase 1 trial, oxytocin was administered via an inhaled route. The study was a controlled trial, though it was not double-blinded.
