Data Monitoring Committee (DMC) Services

Ensure Independent, Expert Oversight of Clinical Trial Data

Leverage a worldwide network of experienced biostatistical and medical experts to provide the appropriate independent oversight to support participant safety and statistical evaluations.

Advarra provides trusted oversight of clinical trials needing an independent data monitoring committee (DMC) (also known as a data safety monitoring board [DSMB]) consistent with US FDA and EU EMA guidelines.

Why Advarra DMC

Accelerate Study Startup

Minimize delays with rapid creation of the DMC charter and statistical plan. Form the committee quickly with our worldwide network of experts.

Optimize Compliance

Save time and resources with truly integrated review services. While the review committees are separate, Advarra coordinates institutional review board (IRB), institutional biosafety committee (IBC), DMC, and endpoint adjudication committee (EAC) reviews to ensure consistency and reduce delays.

Improve Independence

Data monitoring committees must be independent from the sponsor per US FDA and EU EMA guidelines. Separate clinical trial oversight from trial execution and conduct with impartiality from Advarra’s DMC services.

Reinforce Safety Oversight Worldwide

Leverage Advarra’s global reach to ensure overall trial safety. Our DMC and DSMB services comply with both US FDA and EU EMA guidelines for data monitoring committees.

Secure | Compliant | Audit-ready | Flexible

Advarra’s platform for safety oversight administration and reporting provides connectivity and role-based transparency for all parties involved in an Advarra-administered DMC.

  • Compatible with any electronic data capture (EDC) or similar clinical records system
  • Secure biostats working environment
  • Complete audit trail and secure audit ready document repository


When Is DMC/DSMB Review Required?

Independent DMC or DSMB review and oversight is essential for mitigating risks to study participants and ensuring certain types of trials have adequate data safety monitoring plans. US FDA regulation and GCP E6 R2 requires sponsors to have adequate data safety monitoring plans in their clinical protocols. Guidance from US FDA and EU EMA indicate an independent DMC is an effective and appropriate way to provide an adequate safety monitoring plan for clinical trials where:

  • The study endpoint is such that a highly favorable or unfavorable result, or even finding a futility at an interim analysis, might ethically require study termination before its planned completion.
  • There are reasons for a particular safety concern; for example, if the procedure for treatment administration is particularly invasive.
  • There is prior information suggesting the possibility of serious toxicity with the study treatment.
  • The study is performed in a potentially fragile population such as children, pregnant women, the very elderly, or other vulnerable populations, such as those who are terminally ill or of diminished mental capacity.
  • The study is performed in a population at elevated risk of death or other serious outcomes, even when the study objective addresses a lesser endpoint.
  • The study is large, of long duration, blinded, or multi-center/multi-national and would benefit from additional oversight.

If your trial has any of these attributes, establishing an independent DMC or DSMB is likely in order and may be required by the IRB, ethics committee (EC), or regulators.

Leverage decades of statistical experience to help design your overall DMC statistical analysis plan (SAP) for the protocol. Our experts will design and customize a solution to meet your planning and implementation needs.

Our experts provide the necessary programming and validation to complete the tables, listings, and graphs (TLGs) necessary for the DMC.

Services include:

  • Develop DMC SAPs
  • Create SAS-derived dataset programs
  • Create TLG programs
  • Validation of SAS programming per 21 CFR Part 11 standards
  • Prepare periodic statistical reports for the DMC per SAP
  • Serve as unblinded statistician(s) on the DMC


While our DMC Statistical Center typically works with the Advarra-administered DMC, we can also prepare TLGs for DMCs administered by other parties.


What is a data monitoring committee (DMC)?

A DMC or DSMB is often a requirement for clinical trials. The DMC is an independent group of experts that conduct a periodic review of accumulated data during a clinical trial. The primary purpose of the DMC is to report early evidence of benefit or harm, taking into account the safety of the participants and the integrity and validity of the data. The key to an effective DMC is truly independent members. DMC members should not have conflicts of interest that may compromise an unbiased review and recommendation to the sponsor.

What is the difference between a DMC and a DSMB?

The terms DMC and DSMB are essentially synonymous and used interchangeably. The US FDA and EU EMA guidelines both use the DMC’s terminology; however, in practice, these committees are typically called DSMB or independent safety monitoring boards (ISMB). Also, the DMC terminology is more common in the EU, while DSMB is the term most common in North America to describe these independent committees.

What is a DMC or DSMB charter?

The charter defines the overall procedure the committee will follow. Each clinical trial is unique, so the DMC overseeing the trial is created with that specific trial in mind. The charter outlines, among other key elements, how the DMC will conduct its review, the committee membership requirements, meeting timelines, and most importantly, the specific statistical methods used to prepare data for the committee to review.

At Advarra, the charter is created collaboratively with the sponsor or CRO and is a key part of our rapid DMC startup process.

Who serves on a DMC?

While regulatory agency guidelines do not mandate a specific committee composition, all Advarra DMCs follow industry best practice and are typically comprised of:

  • Five or more total members who collectively have the expertise to assess the interim statistical data and risks associated with the clinical trial.
  • At least two members who are experienced biostatisticians.
  • At least one member with specific scientific and medical expertise to evaluate safety.
  • At least one non-scientifically trained member to represent the general perspective of research participants.

DMC membership varies based on the nature of the protocol, and final membership demographics are outlined in the DMC charter in collaboration with the sponsor or CRO.

Turnaround Time

During the trial, the DMC convenes meetings at the frequency outlined in the charter. After the meeting, Advarra provides the DMC’s recommendations to the sponsor/CRO within 1 business day.

Setup time for your study’s DMC or DSMB will depend on the nature of the trial and complexity of programming the statistical tables for presentation to the DMC members. Typically, this process takes a month or more, and is completed in advance of the study activation and first patient visit. The sooner you start the process, the less likely it will impact study startup.
