|---|---|---|---|
| Primary | Frequency of treatment-related adverse events | 20 weeks | Treatment-related adverse events coded by MedDRA will be compared qualitatively between low dose treatment, high dose treatment, and placebo groups |
| Primary | Drug tolerability as measured by number of treatment discontinuations | 20 weeks | The number of patients discontinuing treatment due to adverse events will be assessed between low dose treatment, high dose treatment, and placebo groups |
| Primary | Change in transcriptomic profile from baseline, as measured by RNA-seq (transcriptome biomarker analysis) | 20 weeks | Transcriptome biomarker analysis is widely used to assess dynamic changes in biological systems in response to disease processes and applied stimuli, which cannot be captured with genomic sequencing of DNA mutations and variations. Unravel Biosciences has created a proprietary algorithm for analyzing transcriptome data, identifying underlying signatures of disease progression or recovery. The machine learned gene network approach predicted the use of vorinostat based on restoring a transcriptome signature of Rett syndrome toward a healthy state, which was confirmed preclinically and motivated this clinical trial. The same algorithm will be used to assess time-dependent changes in the transcriptome network signature, to evaluate its ability to capture clinical response data and to measure the extent of restoration of a disease signature back to a healthy state in a human relative to pre-clinical models. |
| Secondary | Change from baseline on PTHS-specific Clinical Global Impression Improvement Scale (CGI-I) | 20 weeks | 7 point Likert scale with 1=very much improved and 7=very much worse |
| Secondary | Change from baseline in PTHS-specific Clinical Global Impression Severity Scale (CGI-S) | 20 weeks | 7 point Likert Scale; 1=normal, 7=extremely ill |
| Secondary | Change from baseline in the Caregiver Impression of Improvement scale (CareGI-I) | 20 weeks | A 5-point Likert scale is used with the following response options: Much Improved (1); Improved (2); Unchanged (3); Worse (4); or Much Worse (5). |
| Secondary | Change from baseline in the Revised Motor Behavioral Assessment (R-MBA) | 20 weeks | Each of the 24 assessment items are scored based on observed or recently reported severity/frequency and scored on a five-point Likert scale between 0 and 4, with higher numbers denoting higher levels of severity/frequency. |
| Secondary | Change from baseline in Observer-Reported Communication Ability Measure (ORCA) | 20 weeks | The ORCA measure consists of 84 total questions with 70 behavioral items within 22 concepts/functions (e.g., refuse object, make choices) that cover expressive, receptive and pragmatic areas of communication, alongside a set of 14 descriptive items that capture important information about the individual's unique ways of communicating. The questionnaire is designed to be completed by the primary caregiver who is most familiar with the individual and the ways they communicate. ORCA measure scoring is done by dedicated statistical algorithm provided by Duke University and response items are not measured using a simple numerical rating scale. |
| Secondary | Change from baseline in the International Cooperative Ataxia Rating Scale (ICARS) | 20 weeks | A total of 19 questions with four subscale domains is used for assessment. Total possible score = 100, with lower scores representing lower disease burden. |
| Secondary | Changes in sleeping habits as measured by modified Child Sleep Habits Questionnaire (CSHQ) | 20 weeks | A modified version of the 45-item caregiver questionnaire will be used. Items are rated on a three-point scale: "usually" if the sleep behavior occurred five to seven times/week; "sometimes" for two to four times/week; and "rarely" for zero to one time/week. Lower scores are suggestive of lower disease burden on sleep behavior |
| Secondary | Change in revised Face Legs Activity Cry and Consolability (FLACC) observational pain tool | 20 weeks | The Face Legs Activity Cry and Consolability (FLACC) tool is a behavioral pain assessment scale used for nonverbal patients who are unable to self-report their level of pain. Pain is assessed through observation of 5 categories including face, legs, activity, cry, and consolability. Each category is scored from 0 to 2 to provide a total score ranging from 0 to 10. Higher scores represent greater symptom burden. The revised FLACC (Malvya, et.al., 2006) incorporates pain behaviors more often observed in cognitively impaired adults and children and has been demonstrated to have a reasonable level of reliability and validity for use in assessing pain in nonverbal children with cognitive impairment. |
| Secondary | Reduction in seizure frequency as measured by seizure diary | 20 weeks | Caregiver-recorded seizure frequency, duration, and quality will be evaluated for evidence of improvement based on reduction in seizure burden |
| Secondary | GI symptom measures relative to baseline using a subset of questions from the Gastrointestinal Symptom Rating Scale (GSRS) | 20 weeks | A subset of 7 questions from the GSRS will be used in the study, each question rated on a 4 point ordinal scale, "0" representing no symptoms and "3" representing significant symptom burden. Lower scores reflect lower symptom burden. |
