Clinical trials call upon a complex network of resources, i.e. parties contracted by the sponsor (e.g. contract research organisations [CROs]) and parties subcontracted by such delegates (e.g. hospitals, clinics, investigators, laboratories, site management organisations [SMOs], monitors, etc.). Therefore, it is imperative that the sponsor has systems and procedures in place to ensure adequate oversight of the quality management of the trial’s tasks & duties irrespective of their primary assignment (sponsor or CRO).

ICH GCP E6(R2) – 5.2.1. “A sponsor may transfer any or all of the sponsor’s trial-related duties and functions to a CRO, but the ultimate responsibility for the quality and integrity of the trial data always resides with the sponsor. The CRO should implement quality assurance and quality control”
ICH GCP E6(R2) – 5.2.2. “Any trial-related duty and function that is transferred to and assumed by a CRO should be specified in writing – ADDENDUM: The sponsor should ensure oversight of any trial-related duties and functions carried out on its behalf, including trial-related duties and functions that are subcontracted to another party by the sponsor’s contracted CRO(s).”
ICH GCP E6(R2) – 5.2.3. “Any trial-related duties and functions not specifically transferred to and assumed by a CRO are retained by the sponsor.”
ICH GCP E6(R2) – 5.2.4 “All references to a sponsor in this guideline also apply to a CRO to the extent that a CRO has assumed the trial related duties and functions of a sponsor”.

3.9 Sponsor Oversight
3.9.1 The sponsor should ensure that the trial design and trial conduct, the processes undertaken, and the information and data generated are of sufficient quality to ensure reliable trial results, trial participant’s safety and appropriate decision making.
3.9.2 The sponsor should ensure that trial processes are conducted in compliance with the trial protocol and related documents as well as with applicable regulatory requirements and ethical standards.
3.9.3 The sponsor should determine necessary trial-specific criteria for classifying protocol deviations as important (i.e., those that impact the rights, safety and well-being of trial participants and the reliability of results).
3.9.4 Decisions related to the trial should be appropriately assessed for their impact on participant’s rights, safety and well-being and the reliability of trial results. Risks related to such decisions should be suitably managed throughout the planning, conduct and reporting of the trial.
3.9.5 The range and extent of oversight measures should be fit for purpose and tailored to the complexity of and risks associated with the trial. The selection and oversight of investigators and service providers are fundamental features of the oversight process. Oversight by the sponsor includes quality assurance and quality control processes relating to the trial-related activities of investigators and service providers.
3.9.6 The sponsor should ensure appropriate and timely escalation and follow-up of issues to allow the implementation of appropriate actions in a timely manner.
3.9.7 The sponsor may consider establishing an IDMC to assess the progress of a clinical trial including the safety data and the efficacy endpoints at intervals and to recommend to the sponsor whether to continue, modify or stop a trial.
3.9.8 Where appropriate, sponsors may also establish an endpoint assessment/adjudication committee in certain trials to review important endpoints reported by investigators to determine whether the endpoints meet protocol-specified criteria. Such committees should typically be blinded to the assigned treatments when performing their assessments, regardless of whether the trial itself is conducted in a blinded manner, to ensure that the data reviewed by committee are as free of bias as possible.
EU Perspective
EU GCP Directive 2001/20/EC Section 3 Art. 7.1 and provide Guidance in this regard, specifying that:
“… the sponsor shall remain responsible for ensuring that the conduct of the trials and the final data generated by those trials comply with Directive 2001/20/EC as well as the EU GCP Directive”
EU Clinical Trial Regulation Chapter XI Art. 71: “Any sponsor may delegate, in a written contract, any or all of its tasks to an individual, a company, an institution or an organisation. Such delegation shall be without prejudice to the responsibility of the sponsor, in particular regarding the safety of subjects and the reliability and robustness of the data generated in the clinical trial”
- The sponsor should ensure oversight of any trial-related duties and functions carried out on its behalf, including trial-related duties and functions that are subcontracted to another party by the sponsor’s contracted CRO(s).
- The sponsor of a clinical trial and the investigator shall ensure that the clinical trial is conducted in accordance with the protocol and with the principles of good clinical practice.
- In order to verify that the rights, safety and well-being of subjects are protected, that the reported data are reliable and robust, and that the conduct of the clinical trial is in compliance with the protocol- and GCP-requirements, the sponsor shall adequately monitor the conduct of a clinical trial. The extent and nature of the monitoring shall be determined by the sponsor on the risk-based basis.
- The sponsor is responsible for choosing the clinical facilities where the clinical trial is to be conducted which are suitable for the conduct of the clinical trial in compliance with the protocol- and GCP-requirements.
- The sponsor is responsible for ensuring that a qualified medical doctor is responsible for all medical care provided to the subject, including the medical care provided by other medical staff.
- The sponsor should ensure that the potential subjects are enrolled into trial only after signing of informed consent in acc. to the GCP standards.
- The sponsor shall notify the ethics committees and the national competent authority of the start of the clinical trial, the end of the recruitment of subjects for the clinical trial and the end of the clinical trial. In accordance with international/national standards, the results of the clinical trial should be reported within one year from the end of the clinical trial.
- The sponsor is responsible for traceability of the investigational medicinal. They shall be stored, returned and/or destroyed as appropriate and proportionate to ensure the safety of the subject and the reliability and robustness of the data generated in the clinical trial. The relevant information regarding the traceability, storage, return and destruction of medicinal products shall be contained in the clinical trial protocol. The documentation thereof shall be contained in the trial master file.
- The sponsor shall notify the national competent authority about a serious breach of GCP principles or of the trial protocol without undue delay but not later than seven days of becoming aware of that breach. A ‘serious breach’ means a breach likely to affect to a significant degree the safety and rights of a subject or the reliability and robustness of the data generated in the clinical trial.
- In order for the sponsor to assess all potentially relevant safety information, the investigator should, as a rule, report to him all serious adverse events.
- The sponsor shall notify the ethics committees and the national competent authority of all unexpected events which affect the benefit-risk balance of the clinical trial, but are not suspected unexpected serious adverse reactions. That notification shall be made without undue delay but no later than 15 days from the date the sponsor became aware of this event.
- The sponsor shall provide the investigator with the investigator’s brochure. The investigator’s brochure shall be updated where new and relevant safety information becomes available, and shall be reviewed by the sponsor at least once per year. If the investigational medicinal product is authorized, and is used in accordance with the terms of the marketing authorisation, the approved summary of product characteristics (SmPC) shall be the IB.
- The sponsor shall ensure that all clinical trial information is recorded, processed, handled, and stored by the sponsor or investigator, as applicable, in such a way that it can be accurately reported, interpreted and verified while the confidentiality of records and the personal data of the subjects remain protected in accordance with the applicable law on personal data protection.
- The sponsor shall ensure that appropriate technical and organisational measures are implemented to protect information and personal data processed against unauthorised or unlawful access, disclosure, dissemination, alteration, or destruction or accidental loss, in particular where the processing involves the transmission over a network.
- The sponsor shall ensure that the sponsor and the investigator keep a clinical trial master file. The clinical trial master file shall at all times contain the essential documents relating to that clinical trial which allow verification of the conduct of a clinical trial and the quality of the data generated, taking into account all characteristics of the clinical trial, including in particular whether the clinical trial is a low-intervention clinical trial. It shall be readily available, and directly accessible upon request, to the Member States. The clinical trial master file kept by the investigator and that kept by the sponsor may have a different content if this is justified by the different nature of the responsibilities of the investigator and the sponsor.
- The sponsor should ensure that the sponsor and the investigator archive the content of the clinical trial master file for at least 25 years after the end of the clinical trial. The content of the clinical trial master file shall be archived in a way that ensures that it is readily available and accessible, upon request, to the competent authorities. Any transfer of ownership of the content of the clinical trial master file shall be documented. The new owner shall assume the responsibilities for orderly archiving of trial documentation. The sponsor shall appoint individuals within its organisation to be responsible for archives. Access to archives shall be restricted to those individuals. The media used to archive the content of the clinical trial master file shall be such that the content remains complete and legible throughout the period referred to in the first paragraph. Any alteration to the content of the clinical trial master file shall be traceable.

Oversight Tools & Solutions
Several tools can be put in place to plan, establish and document oversight as an essential and self-evident core theme of any study’s risk-based quality management: vendor/system audits; review of the qualification and quality management of the subcontractors; set-up and management of a global risk-based quality management plan encompassing all services (irrespective of their primary assignment); task assignment and contract review extended to the subcontractors; co-monitoring (also) of the subcontracted services; CRO’s and SMO’s obligation to escalate quality limiting findings, etc.
In consequence: Sponsor oversight is not just the initial vendor qualification/selection process of a CRO to whom the trial can be entrusted by means of a full-service agreement. The sponsor’s oversight should encompass the full trial. Using a risk-oriented “for purpose” approach, the necessary measures should be well balanced to ensure due quality without loss of cost and time efficiency.
