Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Maximum Predicted Plasma Concentration (Cmax) of ATM and AVI | Up to 15 Days | Cmax is the maximum plasma concentration of ATM and AVI as population pharmacokinetic (popPK) analysis predicts. |
| Primary | Minimum Predicted Trough Plasma Concentration (Cmin) of ATM and AVI | Up to 15 Days | Cmin is the minimum trough plasma concentration of ATM and AVI as popPK analysis predicts. |
| Primary | Area under the Concentration-Time Curve (AUC) of ATM-AVI | Up to 15 Days | AUC is a measure of the plasma concentration of ATM and AVI overtime as popPK analysis predicts. |
| Primary | Plasma Decay Half-Life (t1/2) | Up to 15 Days | Half-life is the time measured for the plasma concentration of ATM and AVI to decrease by one half as popPK analysis predicts. |
| Primary | Apparent Clearance (CL) | Up to 15 Days | ATM and AVI clearance is a quantitative measure of the rate at which ATM and AVI are removed from the blood (rate at which ATM and AVI are metabolized or eliminated by normal biological processes). Clearance obtained after intravenous infusion dose (apparent clearance) is influenced by the fraction of the dose absorbed. |
| Primary | Proportion of Participants reporting Adverse Events (AE) | Baseline up to Day 50 | Proportion of participant AE reports of vital signs, physical examinations, and clinical laboratory tests overall and by age cohort. For each AE the last assessment made prior to the first dose of study drug will be defined as the baseline. |
| Primary | Proportion of Participants reporting Serious Adverse Events (SAE) | Baseline up to Day 50 | Proportion of participant SAE reports of vital signs, physical examinations, and clinical laboratory tests overall and by age cohort. For each SAE the last assessment made prior to the first dose of study drug will be defined as the baseline. |
| Primary | Proportion of Participants reporting AEs leading to discontinuation | Baseline up to Day 50 | Proportion of Participants reporting AEs leading to discontinuation from baseline. For each discontinuation the last assessment made prior to the first dose of study drug will be defined as the baseline |
| Primary | Proportion of Participants reporting AEs resulting in death | Baseline up to Day 50 | Proportion of Participants reporting AE resulting in death from baseline. For each death the last assessment made prior to the first dose of study drug will be defined as the baseline |
| Primary | Proportion of Participants reporting liver injury and acute kidney injury of ATM-AVI relative to Best Available Therapy (BAT) | Baseline up to Day 50 | Proportion of Participants reporting liver injury and acute kidney injury of ATM-AVI relative to Best Available Therapy (BAT) from baseline. For each report of liver and acute kidney injury the last assessment made prior to the first dose of study drug will be defined as the baseline |
