Brief summary
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time) of JNJ-49122944 in healthy male participants after a single intravenous (\[IV\] within a vein) dose administration.
Detailed description
This is a double-blind (neither the researchers nor the participants know what treatment the participant is receiving), randomized (study drug assigned by chance), placebo-controlled (an inactive substance; a pretend treatment \[with no drug in it\] that is compared in a clinical trial with a drug to test if the drug has a real effect), and single-center study. The study will consist of Screening Period (2 to 21 days prior to participants' dose administration), Double-blind Treatment Period (single dose of JNJ-49122944 or placebo on Day 1), and Safety Follow-up Period (4 to 7 days after discharge). The total duration of participation for each participant, including screening, will be up to approximately 4 weeks. Blood samples will be collected for assessment of pharmacokinetic parameters. Participants' safety will be monitored throughout the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs) | Throughout the duration of study (up to 4 weeks) | An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. |
| Maximum Plasma Concentration (Cmax) of JNJ-49122944 | Pre-dose, 0.25, 0.50, 0.75, 1, 1.25, 1.75, 2.75, 4.75, 6.75, 12.75 hour post- dose on Day 1, 24.75 hour post-dose on Day 2, 48.75 hour post-dose on Day 3 | The Cmax is the maximum observed plasma concentration during dosing interval. |
| Area Under the Plasma Concentration Time Curve From Time 0 to Last Quantifiable Time (AUClast) of JNJ-49122944 | Pre-dose, 0.25, 0.50, 0.75, 1, 1.25, 1.75, 2.75, 4.75, 6.75, 12.75 hour post- dose on Day 1, 24.75 hour post-dose on Day 2, 48.75 hour post-dose on Day 3 | The AUC(last) is the area under the plasma concentration time curve from time 0 to the time corresponding to the last quantifiable plasma concentration. |
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity]) of JNJ-49122944 | Pre-dose, 0.25, 0.50, 0.75, 1, 1.25, 1.75, 2.75, 4.75, 6.75, 12.75 hour post- dose on Day 1, 24.75 hour post-dose on Day 2, 48.75 hour post-dose on Day 3 | The AUC(0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z), wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time; C(last) is the last observed quantifiable concentration; and lambda(z) is elimination rate constant. |
| Percentage of Area Under the Plasma Concentration-time Curve Obtained by Extrapolation (%AUC [infinity,ex]) of JNJ-49122944 | Pre-dose, 0.25, 0.50, 0.75, 1, 1.25, 1.75, 2.75, 4.75, 6.75, 12.75 hour post- dose on Day 1, 24.75 hour post-dose on Day 2, 48.75 hour post-dose on Day 3 | Percentage of area under the plasma concentration-time curve obtained by extrapolation (%AUC\[inf,ex\]) is calculated by dividing the difference of AUC(0-infinity) and AUC(0-last) by AUC(0-infinity) and then multiplying by 100 (AUC\[0-infinity\] - AUC\[0-last\])\*100/AUC\[0-infinity\]. |
| Elimination Half-life (t1/2) of JNJ-49122944 | Pre-dose, 0.25, 0.50, 0.75, 1, 1.25, 1.75, 2.75, 4.75, 6.75, 12.75 hour post- dose on Day 1, 24.75 hour post-dose on Day 2, 48.75 hour post-dose on Day 3 | Elimination half-life (t \[1/2\]) is associated with the terminal slope (lambda \[z\]) of the semi logarithmic drug concentration-time curve, calculated as 0.693/lambda(z). |
| Rate Constant (Lambda[z]) of JNJ-49122944 | Pre-dose, 0.25, 0.50, 0.75, 1, 1.25, 1.75, 2.75, 4.75, 6.75, 12.75 hour post- dose on Day 1, 24.75 hour post-dose on Day 2, 48.75 hour post-dose on Day 3 | Lambda(z) is first-order rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve. |

The AUC (infinity) is the area under the plasma concentration-time curve from time zero to infinite time. |
