Descrizione dettagliata
During the study periodic monitoring will be conducted to ensure that the protocol and Good Clinical Practices (GCPs) are being followed.The monitors may review source documents to confirm that the data recorded on CRFs is accurate. The study site may be subject to review by the Institutional Review Board (IRB) and/or appropriate regulatory authorities.
A CRF will be completed for each included subject and will be signed by the investigator or by an authorized staff member to attest that the data is true. Any corrections to entries made in the CRFs, source documents must be dated, initialed and explained (if necessary) and should not obscure the original entry. Qualit assurance will as also be performed regularly on the CRFs.
The primary end point will be analyzed using Time to event (cure, death, relapse etc)analysis and failure rates and hazard ratios will be calculated accordig to categorical drug concentrations with proposed cutt offs.
Secondary end points will be analysed using time to event for occurence of toxicities which will also be corelated to the drug concentrations.
