Trial Outcomes & Findings for RAD001 and Neurocognition in PTEN Hamartoma Tumor Syndrome (NCT NCT02991807)

NCT ID: NCT02991807

Last Updated: 2025-02-17

Results Overview

The primary endpoint will be safety as measured by study drop-out rate due to side effects, comparing everolimus vs. placebo. We will also determine the frequency of adverse events by type and severity. This section displays participant dropout rate and for what reason.

RAD001
RAD001 is formulated as tablets of 5.0 mg or 2.5mg strength, blister-packed under aluminum foil in units of 10 tablets and dosed on a regular basis. RAD001: RAD001 is formulated as tablets of 5.0 mg strength, blister-packed under aluminum foil in units of 10 tablets and dosed on a regular basis. RAD001 tablets should be opened only at the time of administration as drug is both hygroscopic and light-sensitive. Patients will be instructed to take 4.5 mg/m2 of RAD001 orally with a glass of water at regular intervals at the same time in the morning after a light, nonfat breakfast.
Placebo
Matching placebo will be provided as a matching tablet and will also be blister packed under aluminum foil in units of 10. Placebo: Matching placebo will be provided as a matching tablet and will also be blister packed under aluminum foil in units of 10.

SECONDARY outcome

Timeframe: 6 months

Composite score was based on the following: Stanford-Binet Intelligence Scales, 5th Ed (SB-5) non-verbal and verbal working memory standard score; for the SB-5, the minimum score is 40 and the maximum score is 160, where the higher score represents a better outcome. Conners' Continuous Performance Test, 3rd Ed (CPT-3) hit reaction time standard score (reverse coded; standard score generated from T-score); for the CPT-3, the min score is 0 and the max score is 90, where the lower the T-score, the better the outcome. Purdue Pegboard Test (PPT) both hands standard score (generated from T-score); for the PPT, the min score is 20 and the max score is 190, where the higher the T-score, the better the outcome. For the composite score, the higher the score, the better the outcome. The composite score is on the SS metric (M=100, SD=15, min=20, max=180).

SECONDARY outcome

Timeframe: 6 months

Population: Change in motor functioning scores were obtained from Purdue Pegboard Developmental Coordination Disorder Questionnaire (DCDQ). Pegboard motor functioning scores were generated using standard scores, where a higher score indicates a better result (range 0-100). DCDQ motor functioning scores utilize the scale's total score, where higher scores indicate a better result (range 15-75).

Motor functioning will be measured by the Purdue Pegboard (Pegs): Dominant and non-dominant hand combined standard scores and Developmental Coordination Disorder Questionnaire (DCDQ): Total score. This outcome evaluates the change from baseline to 6 months.
