Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The data of this trial will be collected in the form of Case Report Forms (CRFs). The CRFs will be completed and signed by the principal investigator or their authorized representative at each site. All initial entries and subsequent changes should be retained, including the following information: the time and date of entry or change, and the signature of the person making the entry or change. If a subject withdraws from the trial before completion, the reason for withdrawal must be recorded on the CRF. If a subject withdraws due to a dose-limiting adverse event, every effort should be made to clearly record the final outcome.
