Data Safety and Monitoring Committee

The Tisch Cancer Institute at the Mount Sinai Health System places the highest priority on ensuring the safety of patients participating in cancer clinical trials. The Data and Safety Monitoring Committee is responsible for assessing safety and scientific integrity of clinical trials, an integral component of The Tisch Cancer Institute’s institutional and protocol-specific data and safety monitoring plans.

The Committee safeguards the interests of study participants, monitors the overall conduct and progress of the study, makes recommendations regarding continuation of the study, and protects the validity of the study results. Its independent nature ensures an objective and unbiased evaluation.

Membership

The Tisch Cancer Institute Director appoints two co-chairs to the Data and Safety Monitoring Committee. These co-chairs then propose committee members, who must be approved by the Institute’s Director and the Clinical Research Steering Committee. Committee members serve a three-year term. The co-chairs select members based on their expertise, clinical trial experience, reputation for objectivity, absence of conflicts of interest, and knowledge of clinical trial methodology. Committee members represent a broad range of oncologic expertise and sub-specialization and include investigators who are engaged in clinical research activities, protocol oversight, and study design and conduct.

Review Process and Timeline

The committee meets regularly, commensurate with the risk level of the study. It reviews the protocols three months after the first patient is enrolled and then every 3, 6, or 12 months thereafter, depending on the risk level. Reviews end when the study is no longer enrolling new patients and all patients have completed their participation and safety follow-up.

The level of risk to study participants is assessed as follows:

  • High: Research involving greater than minimal risk, which may or may not have direct benefit to the subjects. Risks are high in relation to the anticipated benefits. The Committee conducts reviews every three months while study participants are undergoing study intervention and within the safety follow-up window.
  • Moderate: Risks are reasonable in relation to anticipated benefits and the importance of anticipated resulting knowledge. The Committee conducts reviews every six months while study participants are receiving the study intervention and during the safety follow-up window.
  • Low: The possibility of harm or discomfort is no more than in daily life or routine physical and psychological exams. The Committee conducts reviews every 12 months while study participants are undergoing study intervention and during the safety follow-up window.
  • Exempt. Non-interventional (observational, ancillary, or correlative) trials and survey research do not require Committee review.

The principal investigator and team must submit the following documents to the Committee for review:

  1. Protocol-specific data and safety monitoring packet: Prepare this prior to the review date and submit it electronically.
  2. Adverse event summary report: Supply a cumulative report and frequency log of adverse events, exporting the summary report from the study’s electronic data capture system.
  3. Screening and Enrollment Log: Submit a cumulative report of patients screened for and enrolled in the clinical trial.
  4. Deviation Log: Provide a cumulative report of deviations from the protocol.
  5. Two-stage design with stopping rules: Supply a summary of progress for clinical trials that have a two-stage design with stopping rules. The Committee will not place a hold on the accrual while it reviews the summary and data, unless otherwise specified in the Institutional Review Board-approved protocol. The principal investigator or designee may continue the study as outlined in the Institutional Review Board-approved protocol as soon as the study statistician approves it.

Following review and presentation by the clinical and biostatistics reviewers, the Committee will make one of the following outcome determinations:

  • Approved: The study can continue as planned. We will review it according to the frequency determined by the risk level; researchers need take no additional action.
  • Conditionally Approved: The Committee requires clarifications or additional information. The study can continue while the principal investigator provides the information requested, until the Committee is satisfied. When the Committee is satisfied, it will issue a notice of approval.
  • Suspended: The Committee has substantial concerns regarding the safety, data integrity, and study conduct and requires that accrual be temporarily suspended until the principal investigator resolves all concerns. Upon resolution, the Committee will issue a notice of approval indicating that all significant concerns have been sufficiently resolved.
  • Terminated: The Committee has significant concerns about safety or study conduct and has determined there is greater risk to continue the study than to permanently close it. The Committee communicates this recommendation to the Protocol Review and Monitoring Committee, which shares it with the Institutional Review Board.
  • Requires Re-submission: The Committee determines that the submission is incomplete due to unresolved issues or insufficient information. Typically, the principal investigator must re-submit the report for the next available meeting.
  • Receives a Final Review. The Committee has determined that the study needs no further review. Reviews stop when all study participants have completed their study procedures and are beyond the time point at which they would be likely to encounter study-related adverse events.
