Details and patient eligibility
About
In the proposed trial, patients will be administered ribociclib+everolimus prior to surgical resection of their tumor. Recurrent GBM patients will be randomized into one of the three time-interval cohorts for the first two dose levels.
In the lead-in dose escalation study, the first six subjects (lead-in) will receive ribociclib 400 mg and everolimus 2.5 mg orally-administered in 5 daily doses with the last dose. If one or less patient experiences DLT among the 6 patients, this regimen with ribociclib 400 mg and everolimus 2.5mg will be considered safe and we will continue with the dose escalation phase of the study up to Level 3.
Four dose escalation levels:
Level 0: ribociclib 400mg and everolimus 2.5
Level 1: ribociclib 600mg and everolimus 2.5mg
Level 2: ribociclib 600mg and everolimus 5mg
Level 3: ribociclib 600mg and everolimus 10mg

Inclusion criteria
-
Prior resection of histologically-diagnosed WHO Grade III or IV glioma. A. Glioma patients who have progressed on or following standard (Stupp regimen) therapy, which included maximal surgical resection, temozolomide, and fractionated radiotherapy.
-
Recurrence must be confirmed by diagnostic biopsy with local pathology review or contrast-enhanced MRI.
-
Subjects must have measurable disease preoperatively, defined as at least 1 contrast-enhancing lesion, with 2 perpendicular measurements of at least 1 cm, as per RANO criteria.
-
For gliomas, archival tissue must demonstrate: (a) RB positivity (≥20%) on immunohistochemistry OR no RB mutations on next-generation sequencing (NGS), (b) Chromosomal loss of CDKN2A/B/C OR CDK4/6 or CCND1/2 amplification on array CGH, (c) mTOR+: PTEN loss OR PIK3C2B or AKT3 amplification on aCGH OR mutations for PIK3CA or PIK3R1, or mTOR or PTEN mutations using rhAMP analysis or pS6 positivity on immunohistochemistry (≥10% for pS6).

Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unwilling to use 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

- 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 unwilling to 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.
