PTEN Gene Mutation

University of South Florida

Access to Resources for Patients With PTEN Hamartoma Tumor Syndrome

The survey will collect information regarding number of affected children in household, PTEN mutation type of effected children, age and gender of effected children, Age, neurodevelopmental disorders, medical problems, IQ, and access to clinical care (specialists currently being seen, specialists not able to see and why) of most affected child, research methods and mediums for disorder-specific treatment options for affected children, reasons behind not participating in clinical research options, and Facts (gender, age, if PTEN mutation carrier, work status, relationship to affected children, days per week of caregiving responsibilities, education level) about participant completing survey.

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.

Matching placebo will be provided as a matching tablet and will also be blister packed under aluminum foil in units of 10.

PTEN Hamartoma Tumor Syndrome

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 (delete: each day) in the morning after a light, nonfat breakfast.

RAD001 and Neurocognition in PTEN Hamartoma Tumor Syndrome

A Randomized Double-Blind Controlled Trial of Everolimus in Individuals With PTEN Mutations (RAD001XUS257T)

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.

Working memory will be evaluated using the Stanford Binet 5 or Mullen Scales of Early Learning at 6 months

Processing speed will be evaluated using mean reaction time on the Conner's Continuous Performance Test (CPT)-3.

Fine motor skills will be evaluated using the Purdue Pegboard sub-tests average of both hands

Attention will be measured by Conners' Continuous Performance Test - 3 - Discriminability index (d') and Omissions

Impulsivity will be measured by Conners' Continuous Performance Test-3- Commissions and Bias (B').

Change in global cognitive ability will be measured by Stanford-Binet 5 or Mullen; Full scale, verbal and nonverbal ability (IQ)

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.

Communication ability will be measured by using standard scores of the Peabody Picture Vocabulary Test (PPVT-4), Expressive Vocabulary Test (EVT-2)

Data will be shared with the National Database of Autism Research (NDAR)

sirolimus 6 mg by mouth loading dose and 2 mg by mouth daily in a 28 day treatment cycle. Patients who do not have cancer take the drug for a total of two cycles (56 days) unless they develop unacceptable side effects. Those who have cancer may continue sirolimus beyond cycle 2 until their disease worsens or they develop unacceptable side effects.

A biochemical change is defined as a decrease in certain protein levels (e.g. P-AKT (phosphorylated AKT), total S6, P-S6, and P-4E-BP1) important in cell growth. These are measured by collecting tissue samples which stained and protein levels are measured under the microscope. Scoring will be based on distribution and intensity of staining. Distribution will be scored as 0 (0%), 1 (1% to 50%), and 2 (51% to 100%) to indicate the percentage of positive cells of interest in a single core. The intensity of the signal will be scored as 1 (weak), 2 (moderate), and 3 (strong). The distribution score and intensity score will be summed into a total score (TS).
