---|---|
Experimental: Letrozole
The treatment starting dose will be 2.5mg administered orally once daily. Daily doses up to 10mg and single doses of 30mg have been shown to be safe in prior studies and therefore we expect that letrozole doses up to 20mg in this study will be safe. The recommended phase II dose (RP2D) will be considered the dose that results in ≥ 2uM letrozole concentration in the tumor or the highest dose achieved (20mg daily for cohort level 7) with < 2/6 patients with DLTs. This dose will be planned for future phase II studies to determine potential efficacy. |
Drug: Letrozole Oral Tablet
Administration: Letrozole will be given orally once daily.

- Overall Letrozole AUC in tumor tissue. [ Time Frame: 5 days ]Pharmacokinetic modeling will be used to determine the overall AUC in the tumor tissue to assess for letrozole penetration through blood brain barrier.
- Adverse Events [ Time Frame: The time patients remain on treatment until 30 days after treatment completed ]The number of patients with treatment related toxicity will be assessed using CTCAE v4.0
- Progression free Survival [ Time Frame: From start of treatment until time of progression assessed up to 1 year ]Patients will be followed for response using RANO criteria to determine time from start of treatment to progression.
- Overall Survival [ Time Frame: From start of treatment until time of death assessed up to 1 year ]Patients will be followed from start of treatment until time of death
