New options are needed for postmenopausal patients initially treated with aromatase inhibitors as not all women respond to this first-line treatment, and even those who do respond will likely relapse.

Before the approval of everolimus, second-line treatment options were other steroidal and nonsteroidal aromatase inhibitors as well as estrogen-receptor antagonists such as fulvestrant Faslodex and tamoxifen.

The trial results are published in the New England Journal of Medicine. The premise of the patient, randomized trial was to test whether blocking the phosphatidylinositol 3-kinase PI3K —Akt—mammalian target of rapamycin mTOR pathway would result in prolonged progression-free survival. Signaling through the mTOR pathway had been previously identified as a mechanism of resistance to endocrine therapy in breast cancer. The recommended starting dosage is 4.

At six months into the study, nine patients 32 percent had a greater than 50 percent reduction in space the tumor occupied tumor volume of their largest SEGA tumor lesion. The length of time from when a patient's tumor visibly shrank and then remained stable duration of response for these nine patients ranged from about three months to two and one-half years with a median of days.

Seven of these patients retained the greater than 50 percent reduction in space the tumor occupied at time of last follow up. The FDA approval of Afinitor for adults with progressive neuroendocrine tumors of pancreatic origin was based on a randomized, double-blind, multi-center trial in subjects with locally advanced or metastatic advanced pancreatic neuroendocrine tumors and disease progression within the prior 12 months.

The trial demonstrated a statistically significant improvement in PFS median The study enrolled adults with renal angiomyolipoma as a feature of TSC and 5 adults with sporadic lymphangioleiomyomatosis. Subjects were randomized to be treated with Afinitor 10 mg per day or matching placebo until disease progression or unacceptable toxicity.

CT and MRI scans assessed disease levels at baseline, 12, 24, and 48 weeks and annually thereafter.
