Investigator’s Responsibilities Safety Reporting Medical Care of Trial Subjects Communication with IRB/IEC Essential documents Informed Consent Adequate Resources IP Site Non- compliance Compliance to GCP and reg. requirements Source documents Protocol Compliance Records and reports
Adequate Resources Adequate number of qualified staff, adequately informed about the protocol, IP and their duties Adequate resources • Sufficient Time (competing trials) • Motivation • Adequate facilities • Adequate equipment and support functions Potential for recruiting the required number of suitable subjects ICH GCP Chapter 4.2
Medical Care • A qualifiedphysician (or dentist), who is an investigator • or a sub-investigator, should beresponsible for all trial • relatedmedical (dental) decisions • Investigator should ensure that adequatemedical care • is provided to a subject for ANYadverse events, • including clinically significant laboratory values • With subject’s agreement it is recommended for the • investigatortoinform the subject’s primary physician • about the subject’s participation in the trial • Investigator should make a reasonable effort to • ascertain the reasonfor subject’s withdrawing • prematurely from a trial Medical care ICH GCP Chapter 4.3
Сompliance with GCP Compliance with GCP Investigator should: • Be aware of and should comply with GCP and the applicable regulatory requirements ICH GCP Chapter 4.1.3
Сompliance with Protocol Investigator should: • Review the protocol • Be thoroughly familiar with the IP as described in the protocol, current Investigator’s Brochure, and the product information Compliance with protocol ICH GCP Chapter 4.1.2
Two Roles: Physician and Investigator Routine Medical Care Conduct of a Clinical Trial Person with symptoms is looking for physician to diagnose and treat the illness Investigator is looking for subjects with diagnosis eligible for the clinical trial Investigator collects and reviews, per protocol, relevant info to select eligible subjects Physician collects and reviews, per medical practice, relevant information to make a diagnosis Physician makes diagnosis and gives standard treatment/therapy of choice Investigator enters eligible subject into trial and is obliged to give IP per protocol
Two Roles: Physician and Investigator Routine Medical Care Conduct of a Clinical Trial Physician may change dose, route, administration of drug or drug itself and allow concomitant medication according to standard treatment Investigator follows protocol for dose, route and administration of IP and use of concomitant medication may be restricted Physician performs examinations and procedures to determine Diagnosis and evaluates outcome of treatment Investigator performs examinations and procedures per protocol to obtain data for efficacy and safety evaluation of IP Physician determines schedule of events for each patient Investigator follows schedule of events per protocol Treatment ends when satisfactory outcome is achieved Subject participation in trial is complete per protocol
Compliance with Protocol • The Investigator should sign the protocol (signature page) to confirm his/her agreement to conduct the trial in compliance with the approved protocol Compliance with protocol • The Investigator should not implement any deviation from the protocol without agreement of the sponsor and prior review and approval/favourable opinion of the IRB/IEC EXCEPT ... ICH GCP Chapter 4.5.1, 4.5.2

Adverse Event Any untoward medical occurrence in a patients or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment Safety reporting ICH GCP Chapter1.2
Why Are AEs Important? • Medical Reasons • Regulatory Reasons
Adverse Event-Recording WHERE ? Adverse Event Page in the CRF At each visit if AE occurred WHEN ? ! All AEs must be assessed by investigators and documented in the source documents first and then transferred to CRF ! ICH GCP Chapter 4.9.2
Adverse Event Page Protocol: Site Nr: Investigator: Subject Initials: Subject Nr: Randomisation Nr: Visit Nr: Visit Date: Treatm. given Outcome Serious- ness Adverse Event Trial Drug Duration Intensity/ Severity Causality Investigator Signature ____________________ Date ___________________
Recording AEs • What information is generally collected: • Adverse Event • Dates of Onset and Resolution • Severity: • Mild = aware but tolerable • Moderate = interferes with activities • Severe = unable to do normal activities • Causality: • Not related • Unlikely • Possible • Probable (AE stops when drug stopped) • Highly probable (AE stops when drug stopped and restarts when drug is reintroduced)
Recording AEs • What information is generally collected: • Outcome • Resolved • Resolved with sequelae • Ongoing • Death • Action Taken with Study Drug (dose) • None • Reduced or increased • Interrupted (means temporarily) • Discontinued (means permanently) • Requirement for Treatment – Concomitant Medication • Seriousness
Adverse Drug Reaction (ADR) New medicinal product Marketed medicinal product A causal relationship between a medicinal product and an adverse event is at least a reasonable possibility, i.e. the relationship cannot be ruled out May occur at ANY DOSE! A response to a drug which is noxious and unintended and which occurs at doses normally used in man for prophylaxis, diagnosis, or treating diseases or for modification of a physiological function ICH GCP Chapter1.1
Unexpected Adverse Drug Reaction (UADR) An adverse reaction, the nature and severity of which is not consistent with the applicable product information It is not as you said it would be ! ICH GCP Chapter1.60
Serious Adverse Event (SAE) Any untoward medical occurrence that at any dose results in: • death • life-threatening • inpatient hospitalization or • prolongation of existing hospitalization • persistent or significant disability/incapacity • congenital anomaly/birth defect ICH GCP Chapter 1.50
Planned Hospitalization • Per project requirements, a hospitalization planned prior to a subject’s inclusion in the trial might not be considered an SAE • If a hospitalized subject has an AE that prolongs that hospitalization, then that AE would become an SAE
Pregnancy and Subjects • Most sponsor companies will request that all pregnancies are reported in the same way as serious adverse events i.e., immediately, and using the SAE report form or Pregnancy Notification Form • Upon consent pregnancies are followed until delivery of the child • Child is assessed at birth for any congenital anomaly/birth defect and possibly longer
What is what? AEs ADRs SAEs UADRs
Immediately may mean 24 hours Serious Adverse Event - Flowchart Episode of Myocardial Infarction Complete AE Page YES Is it an Adverse Event ? Is it a Serious Adverse Event ? NO Y E S • Notify the Sponsor/CRO • Complete SAE Report Form • Notify IRB/IEC and RA
