Clinical Trial Summary

Cognitive aging in people with HIV (PWH) is of increasing concern for several reasons: 1) between 52%-59% of PWH experience cognitive impairment known as HIV-Associated Neurocognitive Disorder (HAND) which impacts everyday functioning and quality of life; 2) HAND increases in severity and prevalence with age; and 3) 70% of PWH in the United States will be 50 and older by 2030. Fortunately, cognitive training programs can individually target specific cognitive impairments in PWH and possibly reduce the severity and prevalence of HAND and improve everyday functioning and quality of life. This approach is based around the underlying concept of intra-individual variability as controlled through higher level allocation of cognitive resources, known as executive functioning. This feasibility study will use a two-group pre-post experimental design of adults with HAND including: 1) a 20-hours of Executive Functioning Training group (enroll 60, n=48 with attrition), and 2) a no-contact control (enroll 60, n=48 with attrition). Aim 1 - Feasibility: To determine feasibility and acceptability of the intervention (i.e., attrition, feedback). Exploratory Aim 1 - Cognition: Compare adults who receive Executive Functioning Training to those who receive no training to determine whether they improve in global cognitive ability and overall cognitive IIV. This high impact study is innovative in the following ways: 1) This is the first study aimed to reduce cognitive IIV in PWH. 2) This is the first study to use IIV as a guide to target solely executive functioning training to improve global cognitive ability, which may reduce the severity and prevalence of HAND. 3) Over the last decade, the epicenter of HIV has emerged in the Deep South where this study will occur. Most participants in this study will be older PWH who identify as lower social economic status (SES) and/or African Americans and experience HAND symptoms.

Description:

OVERALL -- A pre-post three-group experimental design will be used. Participants will be recruited from the University of Alabama at Birmingham (UAB) 1917 HIV/AIDS Clinic which has a patient population of +3,600 and is the largest HIV medical provider within 100 miles. Eligible participants will be consented at the UAB Center for Research on Applied Gerontology where a ~2 hr baseline assessment will be administered. Participants' neuropsychological data gathered at baseline will be examined to determine a HAND classification. Only participants with HIV-Associated Neurocognitive Disorder (HAND) will be invited to continue with the study. Stratified random assignment will ensure an equal number of participants in each group by gender, minority status, and with/without executive functioning impairment (i.e., 1 standard deviation below normative mean). After training, participants will complete a posttest assessment. Recruitment/Retention Strategies. As effective in our studies, recruitment/retention strategies will be used. 1) Recruitment materials distributed in the UAB 1917 HIV/AIDS Clinic. 2) Reminder letters and telephone calls will be used before the scheduled visit. 3) Beverages/snacks will be provided (from departmental funds). 5) Secondary contact information will be collected to follow up with lost participants. Intervention Protocol BrainHQ (POSIT Science Inc.) cognitive training modules will be used as in our other studies; these programs have gaming components that encourage adherence. BrainHQ cognitive training products are tested and endorsed by the scientific community. A meta-analysis of computerized cognitive training in older adults found optimal therapeutic effects occurred when training sessions last at most 60 minutes and are administered 1-3 times per week - dosage parameters already incorporated in our study. This self-administered program uses touch-screen technology with tablets which allows computer novices to engage with the training exercises. The intervention will be administered in the research lab of the UAB Center for Applied Gerontology where many of our other studies have been conducted. Working with BrainHQ, when logging on, participants can only receive the individualized cognitive training exercises they are assigned. Executive Functioning Training Group. Those in the Executive Functioning Training Group will engage in exercises requiring one to set shift; that is, to maintain at least two sets of rules and decide which is appropriate to determine the response. In using these training exercises in the Training On Purpose Study (TOPS), the effects size was quite large (d=-0.89). Dosage of 20 hours of training is considered an upper range on how much training is needed to produce an optimal therapeutic effect. No-Contact Control Group. This group will receive no intervention. As this is a pilot/feasibility study, investigators do not have the resources to provide a contact control group. Importantly, in a prior study, investigators established that a no-contact control group and a contact control (sham) group did not significantly differ from each other and both served as an excellent comparison to a cognitive intervention. Instruments Administration time of the assessment will be ~2 hrs. Investigators will use REDCap and BrainBaseline Assessment of Cognition and Everyday Functioning (BRACE+) tablet for administration of the instruments below to reduce tester burden, tester error, and improve the efficiency of data entry and data management, which will save significant staff time and resources. Other cognitive studies as observed in the HIV Neurobehavioral Research Center (HNRC) group employ testing assessments of similar length. BRACE+ was develop in conjunction with HNRC.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Baseline Assessment of Cognitive Training	All participants at baseline will be asked questions about computer use, knowledge about cognitive training, their perceptions about whether they need cognitive training, knowledge about HIV and cognition, etc. Both quantitative and qualitative (i.e., open-ended responses) data will be collected; this is similar to our other studies.	~12 weeks
Primary	Cognitive Training Satisfaction Questionnaire	Used to assess likes/dislikes of the intervention, both quantitative questions and qualitative (i.e., open-ended responses) data are gathered as has been used in our previous cognitive intervention studies to evaluate feasibility and acceptability.	~12 weeks
Primary	Exit Survey	Investigators will administer a brief quantitative and qualitative (i.e., open-ended responses) survey to assess what he/she liked/disliked about the training and how to improve it.	~12 weeks
Primary	Adherence Rates (after study data collection)	Investigators will calculate the adherence rate of the protocol, similar to the investigator's other studies. Ranges will be from 0% to 100%.	Through study completion, an average of 2 years
Primary	Attrition Rates (after study data collection)	Investigators will calculate the attrition rate of the protocol, similar to the investigator's other studies. Ranges will be from 0% to 100%.	Through study completion, an average of 2 years
Secondary	BRACE+ (BrainBaseline Assessment of Cognition and Everyday Functioning)	Cognitive data will be gathered via BRACE+ (BrainBaseline Assessment of Cognition and Everyday Functioning), supported by NIMH R42099964 and Digital Artefacts/UCSD) is a HIPAA compliant tablet-based cognitive assessment platform. This self-administered tool is not literacy dependent (i.e., automated audio/video instructions) and uses validated cognitive tests sensitive to mild-to-moderate cognitive impairments.	~12 weeks
