Developing a Comprehensive Yet Concise DMC Charter
Per FDA, data monitoring committees (DMCs), also referred to as Data and Safety Monitoring Committees (DSMCs) or Data and Safety Monitoring Boards (DSMBs), should operate off of a documented DMC charter.
As an independent group that has access to unblinded clinical trial data and a relatively strong voice in whether a trial continues, DMCs must be carefully planned and managed. To assist with this, FDA recommends that each DMC establish a trial-specific charter with clear operating procedures.
“Charters operate as operational procedures the DMC,” PharPoint’s Sr. Project Specialist and experienced DMC coordinator Victoria Elder, M.S., explains.
An effective charter must define the purpose, responsibilities, and operations of a DMC in a way that is both comprehensive and concise.
“Charters do not need to be overly complex,” Victoria says, “but should have enough information so that everyone involved in the DMC understands their roles and responsibilities with regard to the conduct of meetings.”
Authoring An Effective DMC Charter
So, what should an effective DMC charter look like?
Generally speaking, PharPoint often sees effective charters with apprxoimately 20 pages, appendices included – but length can certainly vary.
“The length of the document depends on the complexity of the study itself, the study design,” Victoria notes. “If a study has multiple parts, say Part A and Part B, and those parts have different objectives, then the DMC Charter may be a bit more complex than a charter for a study with a simpler design adn objective. However, the core information about the DMC composition and fucntion should be very similar.”
While a DMC charter could be written by Sponsors themselves, Victoria also spoke about the value of bringing in an experienced, independent party to help author a charter – especially if maintaining independence between the Sponsor and DMC is a priority for the study. Independence is advised for finding experienced participants for the DMC composition.
PharPoint maintains a robust database of experienced DMC members who hold expertise across a variety of therapeutic areas and indications. PharPoint often helps Sponsors narrow down a list of candidates for inclusion within a committee and can author charters on their behalf.
“The composition of a committee can benefit from being supported by someone who knows the study well enough to recruit members who are experts in their field. This person would be able to offer a lot of good expertise in organizing a DMC to fit the study’s specific needs,” Victoria shares.
“It is important to review any conflicts of interest so [committee members] are able to make recommendations free of bias.”
What Content Should be Included within a DMC Charter?
Criteria and rationale for selection of committee members
Outline and clarification of roles of committee members, including voting and nonvoting members
Procedures for assessing financial and intellectual conflicts of interest for potential DMC members
Procedures for adding or removing members when appropriate or for disbanding the DMC
Meeting Information, Schedule, and Format,including:
Planned frequency of meetings, when additional meetings might be scheduled, and the preferred platform for communications and conditions for convening ad hoc meetings
Who may attend open and closed portions of DMC meetings and whether any members will not attend full meetings
Who will create specific reports and have access to them, where reports will be stored, what reports will be generated in the course of the clinical trial and how they will be transmitted within and outside of the DMC
Handling of meeting minutes for open and closed portions
Definition of a quorum of DMC members
Planned Analyses by Committee and Protection of Data,if applicable, including:
Schedule and basis of planned interim analyses identified in the protocol and/or statistical analysis plan
Analyses associated with prespecified safety considerations
Maintaining Confidentiality of Data, including:
How unblinded analyses will be prepared (e.g., by an independent statistician) for the DMC and at what frequency
How blinding of the trial will be maintained for sponsors, investigators, and subjects
What procedures will be followed to maintain confidentiality of interim comparative data in communications between the DMC, the sponsor, and outside parties
What strategies will be used for maintaining blinding and confidentiality when preparing reports for the DMC open sessions
Who, besides the DMC and independent unblinded statistician, will have access to interim data and reports to the DMC chair
Conclusion
By establishing clear guidelines for the composition, responsibilities, and operational procedures of DMCs, sponsors can safeguard the safety of trial participants and the validity of trial outcomes.
Ultimately, adherence to a well-crafted DMC Charter, informed by FDA guidance and best practice, supports the ethical and effective management of clinical trials, benefiting all stakeholders involved.
As part of PharPoint’s DMC services, we act as an independent partner to Sponsors that can support committee members and manage logistical challenges. Our services also include DMC charter development, authoring, and review.
