Detailní popis

A total of 30 randomized adult participants with Fragile X syndrome will participate in the clinical trial (randomization ratio 1:1 treated vs placebo arms). The expected distribution between sites will be 1:1.

This trial will consist of a Screening period of up to 28 days prior to treatment period. A final follow-up period for safety of 14 days (± 2 days) is planned after the end of treatment. The duration of the study will be approximately 3 months for each participant.

Exploratory Efficacy endpoints for FXS-CTH120-01:

An eye tracker (Tobii Technology, Sweden) will be used to record X and Y coordinates of eye position and pupil diameter while participanta are exposed to stimuli consisting on coloured photographs of adult human faces.
On Baseline visit (From Day -14 to Day -1), on Day 14, and on Day 42.
Biorhythm characteristics using Actigraphy
Časové okno: Between Baseline visit (From Day -14 to Day -1) and Day 14, and between Day 28 and Day 42.

Exploratory Efficacy endpoints for FXS-CTH120-01:

Sleep-wake rhythms will be assessed using an actigraph (GT3X-BT model) placed on the wrist of a non-dominant hand. The actigraph is a non-invasive device, useful for monitoring circadian rhythms and it records consecutive periods of 60 seconds throughout the 24 hours/day.

The minimum actigraphy recording will be at least 7 days.
Between Baseline visit (From Day -14 to Day -1) and Day 14, and between Day 28 and Day 42.
Protein levels of FMRP in peripheral blood
Časové okno: On Baseline visit (From Day -14 to Day -1) and on Day 42.

Exploratory Efficacy endpoints for FXS-CTH120-01:

Venous blood samples (9 mL each) will be obtained by extraction of peripheral blood from participants in a EDTA tube.
On Baseline visit (From Day -14 to Day -1) and on Day 42.
BDNF concentrations in plasma
Časové okno: On Baseline visit (From Day -14 to Day -1) and on Day 42.

Exploratory Efficacy endpoints for FXS-CTH120-01:

Venous blood samples (6 mL each) will be obtained by extraction from a cubital vein from participants. A single venipuncture will be used to obtain three aliquots.
On Baseline visit (From Day -14 to Day -1) and on Day 42.
miRNA profile in plasma
Časové okno: On Baseline visit (From Day -14 to Day -1) and on Day 42.

Exploratory Efficacy endpoints for FXS-CTH120-01:

Approximately, 200 µL of human plasma obtained from blood samples collected for BDNF measurement will be processed to extract RNA enriched in small RNAs. RNA quality and concentration will be assessed using the prior library preparation. Libraries will be sequenced at CRG using Nextseq500 sequencer. Processed reads will be mapped to miRBase database using STAR software, and count tables will be generated with FeatureCounts (Subread package). For differential expression (DE) analysis, read counts will be transformed to log2-counts-per-million (logCPM), and variance will be modelled using the voom approach in the limma package.
On Baseline visit (From Day -14 to Day -1) and on Day 42.
