Per-arm endpoint measurements with 95% confidence intervals where reported. Source: trial results section.

Revised Memory and Behavior Problems Checklist, Reactivity Subscale Primary · Baseline (1 week pre-Nova); post-Nova (8 weeks); 1-month follow-up (12 weeks). For Constellation: baseline (1 week pre-start); post (8 weeks); 2-month follow-up (16 weeks). Constellation could begin up to 12 months after Nova.

The primary outcome variable, reactivity, will be assessed with the RMBPC, which measures the frequency of care recipient behavioral symptoms and care partner reactions to these behaviors. The RMBPC was chosen because it aligns with our theoretical foundation that assumes burden is a result of care partner reactions to behavioral symptoms. The RMBPC is a 29-item caregiver report measure, 5-point Likert scale with frequency measuring from 0 (never occurred) to 4 (daily or more often) and reactivity measuring from 0 (not at all) to 4 (extremely) for a total score between 0-116 for each subscale

Adverse events — posted to ClinicalTrials.gov

Time frame: Care Partners and Care Recipients could be in the study for over 1 year depending on the Care Partner's availability to join the interventions. Care Partners would report on adverse events for themselves and their care recipients from the time they consented to participate through study completion. Care Recipients did not participate in the intervention, but adverse events and serious adverse events were collected.. Reporting threshold: 0%. Adverse-event reports describe events observed during the trial — not all are caused by the drug.

Sponsor's own description

The purpose of this study is to test a revised psychoeducational intervention to help Care Partners for family members with dementia understand and reduce the distressing behaviors that come with progressive dementia. Tele-STELLA (Support via TEchnology: Living and Learning with Advancing Alzheimer's disease and related dementias) is a multicomponent videoconference-based intervention designed to facilitate effective management of behavioral and psychological symptoms common to the later stages of dementia. In the Tele-STELLA intervention, professionals ("Guides") meet with family members ("Care Partners") who care for persons with dementia. Working together, the Care Partners and Guides identify strategies to address upsetting behaviors. The goal of this intervention is to reduce upsetting behaviors and, thus, Care Partner burden.
