A study of cell signalling biomarkers in patients with tuberous sclerosis

A study to validate the assay of biomarkers of the mTOR signalling pathway (p-S6RP(Ser240/244) for mTORC1 and p-AKT (Ser473) for mTORC2) and other non-genetic biomarkers in whole blood samples from patients with tuberous sclerosis complex (TSC): Biomarkers in Patients with Tuberous Sclerosis (BioPaTS)

Patients who are male or female aged 10 to 65 years 4. All medications or interventions for epilepsy (including ketogenic diet and any neurostimulation devices for epilepsy) must have been stable for 4 weeks prior to the screening visit

Exclusion criteria

Exclusion criteria: 1. Patients with a history of pseudo-seizures 2. Patients with clinically significant unstable medical conditions other than epilepsy 3. Patients who have a serious intercurrent illness or uncontrolled disease that could compromise the interpretation of the data from this study 4.

Design outcomes

Primary

MeasureTime frame
Inter- and intra- assay precision measured as % inhibition of the mTOR signal, as measured by electrochemiluminescence (ECL) units at a single timepoint

Secondary

MeasureTime frame
The stability of signal in samples after freeze/thawing cycles and long-term storage (up to 1 month), pre- and post-processing of blood will be assessed by measuring ECL signal strength and % inhibition at a single timepoint
