This is the first session in a series titled “Research 101,” which will provide basic education about doing clinical research.
As some are new to clinical research, it is important to understand clinical trials, how they are conducted and the roles, responsibilities, participants, and procedures that are involved. For this first presentation in the Research 101 series, there will be a review of the different types of research, study designs, phases, and other key aspects of conducting human subjects research.
Approximately 40% of participants enrolled in CTN studies are women. Yet, women face unique issues when it comes to getting help with substance use disorder. It can be especially difficult for women to receive assistance for substance use disorder during or after pregnancy and when navigating the criminal justice system due to social stigma, legal issues, or other barriers.
The CTN prioritizes enrollment of women and minorities in research studies and recognizes the issues related to their participation. Accordingly, this 60-minute web seminar will consider the unique challenges that women face in the criminal justice system while struggling with substance use disorder. This will help research teams have a better understanding of the experience of women, including those that are pregnant and in the criminal justice system, and help researchers manage study retention and follow-up more effectively.
Presenters: Ank Nijhawan, MD, MPH (UT Southwestern Medical Center, Dallas, TX), Jaimie Meyer, MD, MS, FACP (Yale University, New Haven, CT), Mishka Terplan, MD, MPH, FACOG, DFASAM (Friends Research Institute, Baltimore, MD)
Learning Objectives:
- Describe the background and treatment of women with substance use in the criminal justice system.
- Discuss unique challenges of women in the criminal justice system, including considerations for pregnant women.
- Consider how this impacts research participation for women who use substances and pregnant women who use substances.
In this session, representatives from the Office for Human Research Protections (OHRP) will discuss relevant Common Rule requirements and what goes into a meaningful informed consent for research involving participants with substance use disorders.
Learning Objectives:
- Explain why getting meaningful consent is critical to enrolling research participants.
- Describe relevant Common Rule requirements for substance abuse research.
- Describe some of the important components for a meaningful consent.

Introduction to Retention in the NDAT CTN. Presented by Dikla Blumberg, PhD (NDAT CTN Clinical Coordinating Center):
Recruitment and retention are vital aspects of clinical research trials and can factor into the success of a study. Therefore, it is important that researchers understand and identify barriers to meeting recruitment and retention targets and the consequences experienced with poor retention. Additionally, it is helpful to examine historical data available on study retention trends to inform implementation efforts on future studies. Accordingly, this presentation briefly addresses these areas by providing an overview on the topic of study retention, retention within the context of the CTN, and discusses the importance of incorporating strategies and tools for study success.

The “CHEERS” Principle of Participant Retention: More Than Just Techniques. Presented by Frankie Kropp, MS (OV Node) and Mitra Lewis, MS (NDAT CTN CCC):
Good participant retention involves more than just specific techniques; retention depends on the study staff’s overall philosophy of managing and accommodating study participants. One helpful way to think about participant retention is to insert the “CHEERS” principle into study retention efforts– Customer service, Help overcome barriers, Environment, Excellence, Relationship/Respect, and Search. This 20-minute webinar will provide an overview of the CHEERS principle, including specific examples of what sites can do to maximize participant retention.

Utilizing a Robust and Comprehensive Locator Form as a Retention Tool. Presented by Phoebe Gauthier, MA, MPH (NE Node) and Dagmar Salazar, MS (NDAT CTN CCC).
Participant recruitment and retention are critical aspects of conducting quality clinical research projects. The National Drug Abuse Treatment Clinical Trials Network (NDAT CTN), which evaluates behavioral, pharmacological, and integrated treatment interventions for substance use disorders, routinely enrolls participants who may be challenging to locate during the treatment and follow-up phase of a trial. This 20-minute presentation will review one tool for increasing retention—an adapted locator form. This locator form is designed to better facilitate locating participants, especially those with unstable living conditions or with limited contact information. Additionally, this presentation will discuss the form elements beyond conventional locator forms and methods for collecting the information to help increase participant retention.
An Institutional Review Board (IRB) provides ethical review of proposed and ongoing clinical research to ensure the rights and welfare of research participants are protected, and that both the study and investigative team adhere to pertinent regulations governing the conduct of clinical trials. Clinical sites wishing to engage in human subjects research must be paired with an IRB registered with the Office of Human Research Protections, thereby ensuring adherence to all tenets of Good Clinical Practice. This pledge is provided in the form of a Federalwide Assurance (FWA) and is one of the central pillars of a clinical trial. This presentation from Eric Hardter, PhD, RAC, Regulatory Affairs Specialist at the NDAT Clinical Coordinating Center, Emmes Corporation, provides an overview of the basis of and need for a FWA as well as the roles and expectations of key stakeholders, including IRBs, institutions, and researchers involved in clinical studies.
Learning Objectives:
- Describe FWAs and FWA provisions.
- Discuss who needs to obtain FWAs, when, and who is covered.
- Consider the expectations and roles for IRBs, institutions, investigators, and researchers that provide oversight and/or engage in clinical research.
New regulations have established the expectation of a single Institutional Review Board (sIRB) to provide ethical review of a clinical research study. The measure is designed to maintain appropriate protection of study participants and yet streamline federally-funded research reviews by eliminating redundancy and avoiding unnecessary administrative burden. Accordingly, CTN researchers must understand the considerations to factor into selecting a sIRB for a multi-center study.
This presentation from Julia Collins, MD, Protocol Specialist at the NDAT Clinical Coordinating Center at the Emmes Corporation, will describe such considerations based on experiences and lessons learned from research teams working with a variety of sIRBs on seven CTN clinical studies.
Learning Objectives:
- Describe types of sIRBs and evaluate suitability for ethical reviews of specific trials.
- Define sIRB selection criteria as applied to studies across disease areas and study designs.
- Discuss other factors to consider and effective processes to implement when selecting a sIRB.
