Brief Summary:

This is a two center, 2 arm, Phase II study evaluating the combination of Ribociclib and Everolimus in patients with advanced DDL and LMS who have had at least 1 prior systemic therapy. Patients will be enrolled by sarcoma histology into DDL (Arm A) and LMS (Arm B). The purpose of this study is to determine the anti-tumor activity of this doublet therapy in these patient cohorts. Ribociclib will be administered orally at 300 mg/day 3 weeks on/1 week off. Everolimus will be administered 2.5 mg orally on a continuous 28 day cycle. Clinical and laboratory assessments will be made on day 1, d15 of cycle 1 and 2, and day 1 of each subsequent cycle. Tumor response will be assessed by RECIST 1.1 at (CT or MRI) at week 8, 16, 24 and every 12 weeks thereafter. Study drug administration will continue until disease progression, unacceptable toxicity or withdrawal of consent. Patients will be followed until death or are lost to follow-up for analysis of secondary endpoints.

There will be a 1 step registration process for dedifferentiated liposarcoma patients while patients with leiomyosarcoma will require a 2 step registration process. For step 1 of registration, patients must meet all the eligibility criteria necessary for step 1. For step 2 registration, patients must meet the inclusion criteria necessary for step 2 to be enrolled into the study.

  • 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 the 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.

Inclusion Criteria Step 2 (LMS patients only):

- Patients with leiomyosarcoma must have tumors with intact Rb as documented by protein expression by IHC for study entry. Patients without sufficient archival tissue for testing will not be eligible. Please see Section 9.0 for further details on testing and interpretation of results. In the event that a patient has prior sequencing information (i.e. through commercial testing) suggestive of intact Rb, the patient may be included into the study on a case by case basis as determined by the principle investigators. The patient will still be required to submit tissue for Rb determination by IHC, but will not need to wait for these results for study entry.
