The Case for Access to Data Monitoring Committee Charters.

AbstractClinical trials investigating novel or high-risk interventions often use data monitoring committees (DMCs) to ensure that the participants' best interests are safeguarded. The typical DMC charter describes procedures by which the DMC operates, including important details concerning organizational structure, membership, meeting frequency, statistical monitoring guidelines, and contents of DMC reports for interim review. These charters, however, are not routinely publicly available; in some cases, their access could be important to the interpretation of trial results.

Deprioritization of Ongoing Clinical Trials.

To be ethical, clinical trials must exhibit a favorable risk-benefit balance at the time of their initiation. However, in some cases, the expected value of a study decreases while the study is ongoing, due to developments outside of the study itself, such as findings from other studies or an otherwise shifting evidence base. While such situations are acknowledged in the research community, they have not received sufficient attention, given the high costs of uninformative studies, both in material and human capital.

Characterization of key information sections in informed consent forms posted on ClinicalTrials.gov.

Introduction: Recent revisions to the US Federal Common Rule governing human studies funded or conducted by the federal government require the provision of a "concise and focused" key information (KI) section in informed consent forms (ICFs). We performed a systematic study to characterize KI sections of ICFs for federally funded trials available on ClinicalTrials.gov.

Bringing data monitoring committee charters into the sunlight.

Clinical trials investigating novel or high risk interventions, or studying vulnerable participants, often use a data monitoring committee to oversee the progress of the trial. The data monitoring committee serves both an ethical and a scientific function, by protecting the interests of trial participants while ensuring the integrity of the trial results. A data monitoring committee charter, which typically describes the procedures by which data monitoring committees operate, contains details about the data monitoring committee's organizational structure, membership, meeting frequency, sequential monitoring guidelines, and the overall contents of data monitoring committee reports for interim review.

How to limit uninformative trials: Results from a Delphi working group.

To be justifiable, clinical trials must test novel hypotheses and produce informative results. However, many trials fail on this score. A Delphi process was used to establish consensus on 35 recommendations across five domains related to the role of scientific review in preventing uninformative trials.
