Brief Summary:
This phase II trial studies how well abemaciclib works in treating patients with ovarian or endometrial cancer that has an activation of the CDK4/6 pathway and that has come back (recurrent). Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving abemaciclib may work better for the treatment of recurrent ovarian and endometrial cancer.

Detailed Description:

PRIMARY OBJECTIVE:

I. To obtain an estimate of the proportion of patients' progression-free at 16 weeks (16 week progression free survival [PFS] rate) in patients with recurrent ovarian (including fallopian tube and primary peritoneal) or recurrent endometrial cancer following treatment with abemaciclib as a molecularly matched targeted therapy.

SECONDARY OBJECTIVE:

I. To assess objective response rate (ORR) as per Response Evaluation Criteria in Solid Tumors (RECIST), progression free survival (PFS) and safety following treatment with abemaciclib as a molecularly matched targeted therapy.

EXPLORATORY OBJECTIVES:

I. To explore the relationship between response to abemaciclib and somatic gene alterations that lead to CDK4/6 activation in ovarian cancer.

II. To explore the relationship between response to abemaciclib and hormone receptor expression levels as well as somatic gene alterations that lead to CDK4/6 activation in endometrial cancer.

OUTLINE:

Patients receive abemaciclib orally (PO) twice daily (BID) on days 1-28. Patients with tumors that are hormone receptor positive also receive anastrozole or letrozole per standard of care. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days, and then every 12 weeks up to 1 year.

Primary Outcome Measures :
  1. Proportion of patients who are progression-free [ Time Frame: At 16 weeks ]
    Will be calculated with corresponding 95% unadjusted exact binomial confidence interval (CI).


Secondary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: Up to 1 year ]
    Assessed per Response Evaluation Criteria in Solid Tumors (RECIST).

  2. Progression free survival (PFS) [ Time Frame: Time from registration until date of progression or death, assessed up to 1 year ]
    Date of progression will be defined as the date of the first imaging or clinical exam or biochemical occurrence showing disease progression. PFS will be calculated with corresponding 95% unadjusted exact binomial confidence interval. Kaplan-Meier estimates and Kaplan Meier plots of this endpoint will be produced. Two-sided 95% confidence intervals will accompany the Kaplan-Meier estimate of the median.

  3. Incidence of adverse events [ Time Frame: At 16 weeks and up to 90 days after completion of treatment ]
    To assess safety

  4. Clinical benefit rate [ Time Frame: Up to 1 year after completion of treatment ]
    Defined as achieving a confirmed objective response (complete response [CR] or partial response [PR]) or achieving stable disease for a minimum duration of 4 months, will be provided with the exact two-sided 95% confidence interval.

Criteria

Inclusion Criteria:

  • Histologically-confirmed ovarian epithelial (including fallopian tube and primary peritoneal) cancer or endometrial cancer
  • Molecular tumor board confirms that patient's archival ovarian cancer tumor specimen has been assessed using standard of care genomic profiling and demonstrates CDK4/6 activation features
  • Molecular tumor board confirms that patient's archival endometrial cancer tumor specimen has been assessed using standard of care genomic profiling and is of endometrioid histology, has positive hormone receptor expression and lack of Cyclin E gene (CCNE) amplification or retinoblastoma susceptibility gene product (RB) loss
  • At least one prior chemotherapy regimen for the treatment of recurrent ovarian or endometrial cancer
  • Patients who received chemotherapy must have recovered (Common Terminology Criteria for Adverse Events [CTCAE] grade =< 1) from the acute effects of chemotherapy except for residual alopecia or grade 2 peripheral neuropathy prior to enrollment. A washout period of at least 21 days is required between last chemotherapy dose and study initiation
  • Patients who received radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and study initiation
  • The patient is able to swallow oral medications
  • Patient has an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
  • Patient must be willing and able to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures
  • Informed consent must be obtained in writing for all patients prior to performing study/screening procedures and prior to registration into the study
  • Absolute neutrophil count (ANC) >= 1.5 x 10^9/L
  • Platelets >= 100 x 10^9/L
