简要总结
This was a double-blind, placebo-controlled, randomized, single ascending dose, sequential group study. Each subject participated in only 1 treatment period.
The primary objective was to determine the safety of single intramuscular (IM) injections of NAVX 010 in healthy subjects. The secondary objective was to determine the single dose pharmacokinetics (PK) of Gonyautoxin 2 (GTX 2) and Gonyautoxin 3 (GTX 3) following IM administration of NAVX 010 in healthy subjects.
Thirty subjects were studied in 5 groups (Groups A to E); each group consisted of 6 subjects, of which 4 subjects received the Investigational Medicinal Product and 2 subjects received placebo. All subjects completed the study and data for all subjects were included in the safety analyses. A total of 20 subjects received NAVX-010 and were included in the PK population and subsequent PK analysis.

Thirty subjects were studied in 5 groups (Groups A to E); each group consisted of 6 subjects, of which 4 subjects received the Investigational Medicinal Product (IMP; NAVX-010) and 2 subjects received placebo. All subjects completed the study and data for all subjects were included in the safety analyses. A total of 20 subjects received NAVX-010 and were included in the PK population and subsequent PK analysis.
This study comprised healthy male subjects of any ethnic origin, aged between 18 and 45 years, inclusive, and with a body mass index (BMI) between 18.0 and 32.0 kg/m2, inclusive.
Dose levels of NAVX-010 were 2, 8, 25, 50, and 75 mcg. Doses were administered as IM injections into the deltoid muscle in the fasted state. The IMP was supplied in glass vials containing 1.2 mL solution at a total GTX 2 and GTX 3 concentration of 42 mcg/mL (at a relative epimer ratio of 62% GTX 2:38% GTX 3).

结局指标
主要结局
Adverse events related to NAVX-010
时间窗: Monitored from dosing day until 5 days after dosed
Any signs or symptoms will be observed and elicited at least once a day by open questioning. Subjects will also be encouraged to spontaneously report AEs occurring at any other time during the study. Any AEs and remedial action required will be recorded in the subject's source data. Subjects experiencing AEs will be followed clinically until their health has returned to baseline status or until all parameters have returned to normal or have otherwise been explained.
Oral body temperature changes
时间窗: BT measured at screening day, check in day, -1 hour relative to dose, 24 hrs postdose and at day 5 after dosed.
Oral body temperature in °C (BT) will be measured. All measurements will be taken as single readings. Measurements will be repeated once if outside the relevant clinical reference ranges. If repeated, the repeat value will be used in the data analysis. Clinical research unit reference ranges will be applied.
12-lead ECG measurements changes
时间窗: 12-lead ECG will be measured at: screening day; check in day; 0.5, 1, 6, 12 and 24 hous postdose and day 5 after dosed.
At check-in, 12-lead ECG will be recorded in triplicate in the supine position for baseline measurements. The average value for each ECG parameter will be calculated as the baseline value. At all other times, a single 12-lead resting ECG with a 10-second rhythm strip will be recorded after the subject has been supine for at least 5 minutes.The 12-lead ECG will be repeated once if either of the following criteria apply:The QTcF is \>450 ms; The QTcF change from baseline (check-in) is \>60 ms. Additional 12-lead ECGs will be performed at other times if judged to be clinically appropriate or if the ongoing review of the data suggests a more detailed assessment of ECGs is required. The ECG machine will compute the PR, QT and QTc intervals, QRS duration and heart rate. The QT interval will be corrected for heart rate using Fridericia's formula.
Changes in cardiac rhythm monitored by telemetry
时间窗: Continuous telemetry monitoring from -1 hour to 24 hour relative to dose. Telemetry strips will be printed out at 2, 3, 4 and 5 hours postdose.
Cardiac rhythm will be monitored by telemetry. Telemetry strips will be printed out at the times indicated in the Study Plan. In addition, staff members will be instructed to print out ECGs if either of the following criteria apply: The QTcF is \>450 ms; The QTcF change from baseline (check-in) is \>60 ms. In such an event, ECGs will continue to be printed out every 20 minutes until the QTcF value has returned to normal.
Changes in clinical laboratory evaluations
时间窗: Clinical laboratories evaluations will be measured at: screening day; check in day; -1 hour and 24 hour relative to dose and day 5 after dosed.
Blood and urine samples will be collected for clinical laboratory evaluations at the times indicated in the Study Plan. Additional clinical laboratory evaluations will be performed at other times if judged to be clinically appropriate or if the ongoing review of the data suggests a more detailed assessment of clinical laboratory safety is required. The following evaluations will be performed: Serum biochemistry, hematology, coagulation, urinalysis and serology.
Changes in blood glucose and phosphorous evaluations
时间窗: The evaluations will be measured 30 minutes and 1 hour post adminitration of the drug.
Blood samples will be collected for serum glucose (mg/dL) and phosphorous (mg/dL) evaluations.
Physical examination changes
时间窗: Physical examination will be performed at: check in day, 1 and 24 hours after dose administration and at day 5 after dosed.
A full physical examination will be performed at the times indicated in the Study Plan and an abbreviated physical examination may be performed at other times.
Changes in the general wellbeing of the subject
时间窗: The questionnaire will be conducted every hour for 12 hours postdose and at approximately 24 hours postdose.
Subjects will be asked to complete a clinical study questionnaire to assess tolerance to the study drug, with the assistance of a suitably trained CRU staff member. Subjects will be asked questions about their general wellbeing and the injection site over the period either since dosing or since the last questionnaire, as applicable. In addition, the injection site will be assessed by the CRU staff member conducting the questionnaire.
Blood pressure changes
时间窗: BP: measured at screening day, check in day, continuous monitoring during dose day (until 24 hrs) and day 5 after dosed.
Systolic and Diastolic blood pressure in mmHg (BP), will be measured. At check-in, blood pressure, will be measured in triplicate within a 10-minute window. The median value for systolic and diastolic blood pressure, will be used as the baseline value in the data analysis. All other measurements will be taken as single readings. Measurements will be repeated once if outside the relevant clinical reference ranges. If repeated, the repeat value will be used in the data analysis. Clinical research unit reference ranges will be applied.
Heart rate changes
时间窗: HR: measured at screening day, check in day, continuous monitoring during dose day (until 24 hrs) and day 5 after dosed.
Heart rate in bpm (HR) will be measured. At check-in, heart rate will be measured in triplicate within a 10-minute window. The median value for heart rate will be used as the baseline value in the data analysis. All other measurements will be taken as single readings. Measurements will be repeated once if outside the relevant clinical reference ranges. If repeated, the repeat value will be used in the data analysis. Clinical research unit reference ranges will be applied.
Respiratory rate changes
时间窗: RR: measured at screening day, check in day, continuous monitoring during dose day (until 24 hrs) and day 5 after dosed.
Respiratory rate in breaths/min (RR) will be measured. At check-in, respiratory rate will be measured in triplicate within a 10-minute window. The median value for respiratory rate will be used as the baseline value in the data analysis. All other measurements will be taken as single readings. Measurements will be repeated once if outside the relevant clinical reference ranges. If repeated, the repeat value will be used in the data analysis. Clinical research unit reference ranges will be applied.
Oxygen saturation changes
