Trial Outcomes & Findings for Sirolimus to Treat Cowden Syndrome and Other PTEN Hamartomatous Tumor Syndromes (NCT NCT00971789)

NCT ID: NCT00971789

Last Updated: 2015-09-30

Results Overview

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).

Measure
Sirolimus Patients
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.

PRIMARY outcome

Timeframe: Baseline, day 14, and day 56

Population: No patient underwent biopsy after the study treatment, so no such tissue analysis was done.

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.
