Summary

This research study is evaluating a drug called Avelumab alone and in combination with Talazoparib or Axitinib as a possible treatment for recurrent or metastatic endometrial cancer.

Description

This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is still being studied and that research doctors are trying to find out more about it-such as the safest dose to use, the side effects it may cause, and if the drug is effective for treating different types of cancer. It also means that the FDA (the U.S. Food and Drug Administration) has not yet approved the drug for use in patients, including people with Metastatic Endometrial Cancer.

Avelumab is a drug that may stop cancer cells from growing by enabling the activation of the immune system. Avelumab blocks an immune inhibiting signal that can impair the ability of the immune system to attack cancers.

Talazoparib is a drug that stops the activity of a protein (called PARP) that's involved in repairing damage to the DNA within your cells. When PARP is turned off by Talazoparib in cancer cells, DNA damage cannot be repaired and leads to the death of the cancer cells.

Axitinib is a drug that may stop cancer cells from growing by blocking certain proteins that cancer cells use to form new blood vessels, which the cancer needs in order to grow.

In this research study, the investigators are looking to see whether Avelumab, the combination of Avelumab and Talazoparib, or the combination of Avelumab and Axitinib are effective in treating recurrent and Metastatic Endometrial Cancer.

Additionally, the investigators are looking to see if participants whose tumors contain a particular genetic make-up will have better response to Avelumab, the combination of Avelumab and Talazoparib, or the combination of Avelumab and Axitinib.

Eligibility

Yes No Not Sure

Inclusion Criteria

Participants must be classified into one of the following cohorts of recurrent or
persistent endometrial cancer of any histology
The MSI/POLE cohort includes endometrial cancers that are
-MSI-H as determined by immunohistochemical complete loss of expression (absence of
nuclear immunoreactivity) of at least one of the mismatch repair genes MSH2, MSH6, MLH1 and
PMS2. This test is now done routinely for every newly diagnosed endometrial cancer patient
in most centers in the US
And/OR
-POLE-mutated, i.e. endometrial cancers known to harbor mutations in the exonuclease
domain (amino acid residues 268-471) of polymerase e (POLE) as determined by targeted
sequencing or other next generation sequencing assay. Any Clinical Laboratory Improvement
Amendments (CLIA)-approved genomic test documenting mutations in the exonuclease domain of
POLE gene (amino acid residues 268-471) in the tumor will be accepted as proof of presence
of POLE mutations and will lead to classification into this patient cohort
The MSS cohorts include
Endometrial cancers that are MSS as determined by normal immunohistochemical nuclear
expression of all the mismatch repair genes MSH2, MSH6, MLH1 and PMS2. Tumors which
have not been sequenced for POLE mutations (i.e. their POLE mutations status is
Prior Therapy
unknown) but are MSS, will be included in this cohort
All patients must have measurable disease as defined by RECIST 1.1. Measurable
Prior hormonal therapy is allowed
disease is defined as at least one lesion that can be accurately measured in at
Patients must NOT have received any class of drugs targeted to the PD-1/PD-L1 pathway
least one dimension (longest diameter to be recorded). Each lesion must be >= 10
mm when measured by CT, MRI or caliper measurement by clinical exam; or >= 20 mm
when measured by chest x-ray. Lymph nodes must be > 15 mm in short axis when
measured by CT or MRI
There is no upper limit of prior therapies but patients must have had one prior
Participants must have normal organ and marrow function as defined below
chemotherapeutic regimen for management of endometrial carcinoma. Initial treatment
absolute neutrophil count >1,500/mcL
may include chemotherapy, chemotherapy and radiation therapy, and/or
platelets >100,000/mcL
consolidation/maintenance therapy. Any platinum based chemotherapy (single agent
platinum or any platinum doublet) administered in conjunction with primary radiation
total bilirubin within normal institutional limits
as a radio-sensitizer WILL be counted as a systemic chemotherapy regimen. Furthermore
patients who have only received chemotherapy in the adjuvant setting will be eligible
creatinine within normal institutional limits OR
for the study
Please note: creatinine clearance (CLCR) should be estimated according to the
Cockcroft-Gault formula as
Patients must NOT have received any prior PARP inhibitor therapy (for patients being
considered for the avelumab/talazoparib cohort only)
Patients must NOT have received prior axitinib (for patients being considered for the
avelumab/axitinib cohort only)
Age of 18 or greater years. Because insufficient dosing or adverse event data are
currently available on the use of Avelumab, talazoparib, and/or axitinib in
participants < 18 years of age, children are excluded from the study. Endometrial
cancer is very rare in the pediatric population
ECOG performance status 0 or 1 (reference Appendix A for ECOG performance status
criteria)
Ability to understand and the willingness to sign a written informed consent document
Availability of a formalin fixed paraffin embedded (FFPE) block of cancer tissue
Additional inclusion criteria for the avelumab/axitinib cohort
OR 15 unstained 5-micron slides from the original surgery or biopsy or from a
biopsy of recurrent disease
hemoglobin ≥ 9g/dL
AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal
creatinine clearance ≥60 mL/min/1.73 m2 for participants with creatinine levels above
institutional normal
CLCR={[(140-age) × weight)]/(72 x SCR)} × 0.85 where CLCR (creatinine clearance) is
measured in mL/min, age is expressed in years, weight in kilograms (kg), and SCR (serum
creatinine) in mg/dL
NOTE: Patients with moderate renal impairment (defined as an estimated creatinine clearance
of 30-59 mL/min) will receive a reduced starting dose of Talazoparib at 0.75 mg PO QD
Participant must not be pregnant or breastfeeding given that avelumab is an agent with
unknown effects in pregnancy and breastfeeding and the potential for teratogenesis
Females of childbearing potential are defined as those who are not surgically sterile
(i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or
post-menopausal (defined as ≥ 12 months with no menses without an alternative medical
cause). Serum pregnancy test (for females of childbearing potential) negative at
screening
The effects of avelumab on the developing human fetus are unknown. For this reason and
because some immunomodulatory agents are known to be teratogenic, women of
child-bearing potential must agree to use adequate contraception (hormonal or barrier
method of birth control; abstinence) prior to study entry and for the duration of
study participation. Should a woman become pregnant or suspect she is pregnant while
she or her partner is participating in this study, she should inform her treating
physician immediately
Toxicities of prior therapy (excepting alopecia and sensory neuropathy) should be
resolved to < grade 2 per the revised NCI Common Terminology Criteria for Adverse
Events (CTCAE) version 4. All appropriate treatment areas should have access to a copy
of the CTCAE version 4. A copy of the CTCAE version 4 can be downloaded from the CTEP
website at: <http://ctep.cancer.gov>
Participants must have adequately controlled blood pressure (BP) with or without
antihypertensive medications, defined as systolic BP that must be ≤140 mmHg and
diastolic BP that must be ≤90 mmHg on two separate BP readings taken at least 1 hour
apart at screening
Participants must have LVEF ≥ lower limit of normal (LLN) as assessed by either
multigated acquisition (MUGA) scan or echocardiogram (ECHO)

nitrosoureas or mitomycin C) prior to entering the study or those who have not
recovered from adverse events due to agents administered more than 4 weeks earlier
Participants with known brain metastases should be excluded from this clinical trial
because of their poor prognosis and because they often develop progressive neurologic
dysfunction that would confound the evaluation of neurologic and other adverse events

formulations, or compounds of similar chemical or biologic composition to avelumab
