E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time. |
Merck llevará a cabo investigaciones biomédicas futuras con las muestras obtenidas específicamente con estos fines durante este ensayo clínico. Estas investigaciones tendrán por objeto el análisis de biomarcadores para abordar aspectos nuevos que no se describen en otras partes del protocolo (como parte del ensayo principal) y solo se llevarán a cabo en muestras de los sujetos que hayan otorgado el consentimiento correspondiente. El objetivo de la obtención de muestras para investigaciones biomédicas futuras consiste en estudiar e identificar biomarcadores que proporcionen información a los científicos sobre las enfermedades y sus tratamientos. El objetivo último es utilizar tal información para desarrollar fármacos más seguros y eficaces y/o para garantizar que los pacientes reciban la dosis correcta del fármaco adecuado en el momento preciso. |
