NCT05344989

Brief Summary

This is a Phase 1, first-in-human (FIH), double-blinded, placebo-controlled study where healthy subjects are randomly allocated to receive APNmAb005 or placebo. Approximately 5 dosing groups (cohorts) are planned with 8 subjects (randomized to 6 active: 2 placebo) per cohort. the starting dose of APNmAb005 is 5 mg/kg and the anticipated doses for subsequent cohorts are 10, 25, 50 and 70 mg/kg. A Safety Review Team (SRT) will review data on an ongoing basis throughout the study and before progression to the next dose level cohort. Subjects will receive a single dose of either APNmAb005 or placebo administered as a single IV infusion on Day 1 of the study and will remain in the study center until Day 3 (48 hours after dosing). They will return to the study center for 7 outpatient visits. The duration of the study, excluding screening, is approximately 71 days.

Outcome Measures

Primary Outcomes (7)

  • Number of subjects with Adverse Events (AEs)

    Defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. Data collected by subject observations and data collected on AE page of electronic Case Report Form (eCRF), or other documents relevant to subject safety.

    Day 70

  • Number of subjects with Treatment-emergent AEs (TEAEs)

    Defined as any event not present before exposure to study drug or any event already present that worsens in intensity or frequency after exposure. Data collected by subject observations and data collected on AE page of electronic Case Report Form (eCRF), or other documents relevant to subject safety.

    Day 70

  • Number of subjects with Serious Adverse Events (SAEs)

    Defined as any AE for which there is a reasonable possibility that the study drug caused the AE. Data collected by subject observations and data collected on AE page of electronic Case Report Form (eCRF), or other documents relevant to subject safety.

    Day 70

  • Number of subjects with AEs resulting in Study Discontinuation

    Data collected by subject observations and data collected on AE page of electronic Case Report Form (eCRF), or other documents relevant to subject safety.

    Day 70

  • Number of participants with Vital Sign Abnormalities

    Measured by systolic and diastolic blood pressures, pulse rate, respiratory rate and body temperature.

    Day 70

  • Number of participants with Electrocardiogram (ECG) Abnormalities

    Measured by 12-lead ECG

    Day 70

  • Number of participants with Clinical Laboratory Abnormalities

    Measured by hematology, coagulation, serum chemistry and urinalysis.
