End point description |
Plasma Concentration of JNJ-53718678 was reported. PK analysis set included all subjects who received JNJ-53718678 and for whom at least one PK concentration was reported.Here, 'n' (number analyzed) represents number of sujects with available data for each specified timepoints. Here, ’99999’ indicates that data was not collected for this time point because sample collection was not performed as prespecified in the protocol.

RSV Viral Load Over Time | ||||||||||||||||||||||||||||||||
End point description |
RSV viral (RSV B) load was measured over time by quantitative reverse transcription polymerase chain reaction in the nasal swab specimens collected at the clinic visits and at home. Efficacy analysis set included all subjects who were randomised, treated (took at least 1 dose), and had a RSV infection confirmed by central laboratory analysis, excluding subjects infected with a co-pathogen at baseline not identified during screening, analysed as randomised. Here, 'n' (number analysed) represent number of subjects with available data for each specified timepoints. Here, ’99999’ indicates that data was not collected for this time point because sample collection was not performed as prespecified in the protocol.

Date |
Amendment |
||
21 Jun 2019 |
The purpose of this amendment was to correct an inconsistency regarding the classification of Cytochrome P450 3A4 (CYP3A4) inhibitors and CYP3A4 inducers in the concomitant therapy section and to update the exclusion criteria to clarify that enrollment of subjects during the follow-up phase of another clinical study was allowed. |
||
11 Dec 2019 |
The purpose of this amendment was to ensure consistency between different sections, to clarify, and make minor corrections to different parts of the protocol. In addition, regulatory feedback from competent authorities was incorporated. |
||
03 Jun 2020 |
The purpose of this amendment was to implement a risk mitigation plan (including dose modifications) following an exposure (Cmax)-related important potential risk of QT interval prolongation identified in the thorough QT Study 53718678RSV1009 in healthy adult subjects. |
||
10 Jul 2020 |
The purpose of this amendment was to implement recommendations regarding cardiac safety and concomitant medications by Health Authorities. |
||
03 Aug 2020 |
The purpose of this amendment was to implement recommendations regarding cardiac safety and concomitant medications by Health Authorities. |
||
07 May 2021 |
The purpose of this amendment was to replace the oral suspension formulations of rilematovir and placebo by oral film-coated tablets, to specify the clinical management of laboratory-confirmed SARS-CoV-2 infection, diagnosed during the study and to add specifics on the administration of a locally approved (including emergency use-authorized) coronavirus disease 2019 (COVID-19) vaccine during the study. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
As the study was terminated early due to low number of subjects enrolled, some efficacy analyses were not performed as per change in the planned analysis. Hence, data was collected and analyzed for safety and selected efficacy parameters only. |
