What is a DSMB? • DSMB is a formally appointed independent group of individuals with scientific expertise and lay representation that reviews accumulated research data from an ongoing clinical trial.
Need for DSMB • All clinical trials require safety monitoring but not all trials require monitoring by a DSMB. • All Phase III randomized comparative trials. • Other higher risk trials. • Large multiple site trials.
Options for Data Monitoring • Federal regulations require that IRB determine requirement for DSMB. • PI or project manager may monitor Phase I and II trials. • A group of Sponsor’s representatives may monitor trials. • Monitoring should commensurate with risks. 1998 NIH policy statement
Points to consider • Some government agencies have required DSMB monitoring for selected trials. • If the trial is accruing very quickly, would a DSMB be practical? • Current FDA regulations impose no requirements for the use of a DSMB except under 21 CFR 50.24* (*exception from IC requirements for emergency research where human subjects may be in a life-threatening situation)
Trials monitored by DSMB at MDACC • Randomized and/or blinded • Non-randomized but referred by IRB • High risk trials • Community Clinical Oncology Program (CCOP) trials
Issues to be Addressed at DSMB meeting • Should the study be stopped? • Inadequate accrual • Increased safety concerns • Have they met the stopping rule • Apparent outcome differences • Futility • Is there a need to change the study design? • Is additional data needed for adequate review to be completed? • Timing of the next review of the study.
UTMDACC DSMB Policy • Per UTMDACC policy, a DSMB will monitor: • (1) all randomized studies that originate at MDACC or that are coordinated or analyzed by the MDACC and are not being monitored by another Data Safety Monitoring Board, unless exempted by the MDACC IRBs; and • (2) any other non-randomized studies referred by the MDACC IRBs to the DSMB. • (HSRM 17.070 DSMB By-Laws)
Protocol Selection for MDACC DSMB DSMB oversight may be requested by: • PI - Single UTMDACC study- UTMDACC PI of consortium study • IRB • CCOP DSMB oversight waived if: • PI sends waiver request to IRB and may be approved if determined to be low risk.
Committee Membership of MDACC DSMB • No more than 15 members • Includes physicians to interpret toxicity and outcome differences • Statisticians to evaluate methodology and interpret probability statements (p-values) • Lay members as participant advocates • 50% of members from outside UTMDACC to prevent bias
Review Frequency at MDACC • Annual review is required • Review frequency may increase based on: • Accrual • Reporting requirements in the trial • Level of risk to the subject/s
Pre Meeting • Eight weeks prior to meeting the PI and biostatistician are notified of trial presentation • PI provides data to Biostatistician • Biostatistician analyzes data and completes the report • One week before the meeting, the biostatistician provides the report to DSMB only
Biostatistical Report Report prepared by biostatistician and presented to DSMB for review include • Accrual rates • Patient Characteristics • Eligibility and Evaluability • Efficacy • Toxicities • Adverse Events • Treatment Related Deaths • Maximum Toxicity • Special Toxicity Monitoring • Secondary Malignancies
Biostatistical Report • Confidential • Not available to the PI or other investigators • PI is made privy to trial results and analyses only after the DSMB officially releases those results to the PI
DSMB Meeting(DSMB Meets Every Other Month) PI & biostatistician present study & answer committee questions PI asked to leave the room Biostatistician discusses data and outcomes by treatment arm Biostatistician asked to leave the room After Discussion, Motion made & voted on by members
Common Outcomes • Appropriate to continue study. • Additional information from PI or biostatistician is requested. • DSMB recommends revisions/amendments. • CNPE for safety/efficacy concerns. • Closure due to futility.
Post Meeting • DSMB provides memo to PI and biostatistician regarding protocol outcome • DSMB provides memo to IRB listing outcome for each protocol presented
All Revisions/Amendments of DSMB Designated Protocols PI revises protocol DSMB Designee/Scientific Editorreviews revision(s) REJECTED APRPOVED Revision not appropriate per DSMB Designee/Editor and is returned. PI notified of changes required. Moves to IRB review
PI requests to the DSMB • Close trial to new patient entry • Request to stop the trial • Cease monitoring the trial and release trial results • Release interim results to the PI or department chair for planning of future trial • Release interim results for publication These requests can be addressed anytime and are not restricted to scheduled meeting times.
PI responsibilities • PI needs to request permission from the DSMB to publish Interim results for a trial • Copies of manuscripts or abstracts that are to be published must be submitted to DSMB The DSMB plays no role in developing publications but may make recommendations
DSMB Conclusions • Protects patient’s interests and scientific integrity of trial/s. • Uses statistical analyses to provide expert guidance. • May serve as scientific reviewer for trial/s.
