Brief summary: In the proposed trial, patients will be administered ribociclib prior to surgical resection of their tumor. Patients will be enrolled in time-intervals sequentially (non-randomized). All patients will be orally-administered 5 doses of LEE011 (900 mg/d) with the final dose occurring at one of 3 intervals before brain tumor resection.

Detailed description: 900 mg/d is the maximally tolerated dose (MTD), as determined in a recent Novartis-sponsored Phase I study for advanced solid tumor patients. The recommended dose expansion and Phase 2 is 600mg/d for 3 weeks on and 1 week off. Due to drug pharmacokinetics, the MTD (900mg) dose will be used for pre-surgical dosing in order to maximize the opportunity to identify relevant tumor pharmacokinetic (PK) and pharmacodynamics (PD) endpoints.

To assess the PK, and PD endpoints listed above, cerebrospinal fluid (CSF) and brain tumor tissue will be collected intraoperatively (for gliomas, enhancing and non-enhancing tumor tissue will be collected and analyzed separately). Additionally, blood samples will be obtained at 0.5, 1, 2, 4, 6, 8, and 24 hours after the final ribociclib dose is administered.

Patients with tumors demonstrating positive PK and PD effects will continue treatment with ribociclib (21 days on, 7 days off) after surgery. This will constitute the Phase II component of the study. Patients will be treated until unacceptable toxicity is observed, or until disease progression as assessed by radiographic or clinical metrics. Preliminary rates of progression-free survival in patients with high-grade gliomas and high-grade meningiomas treated with ribociclib will be measured through radiographic and clinical response metrics, specifically Response Assessment in Neuro-Oncology (RANO) criteria and investigator discretion. Overall survival in patients with high-grade gliomas and high-grade meningiomas treated with ribociclib will be assessed by medical record review and survival follow up.

* Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 3 months after the last dose of study treatment. Highly effective contraception methods include:

  * Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
  * Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
  * Male sterilization (at least 6 months prior to screening) with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate. For female subjects on the study the vasectomized male partner should be the sole partner for that subject.
  * Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate \<1%), for example hormone vaginal ring or transdermal hormone contraception.
  * In case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
  * Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction.
* Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
* Sexually active males unless they use a condom during intercourse while taking drug and for 21 days after stopping treatment and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
