Fulvestrant with or without Palbociclib and Avelumab in Treating Patients with Hormone Receptor Positive, HER2 Negative Metastatic or Recurrent Breast Cancer That Cannot Be Removed by Surgery Previously Treated with CDK and Endocrine Therapy

Status: Active

Description

This randomized pilot phase II trial studies how well fulvestrant with or without palbociclib and avelumab works in treating patients with hormone receptor positive, HER2 negative breast cancer that has spread to other parts of the body or that has come back after a period of improvement and cannot be removed by surgery, and have been previously treated with CDK and endocrine therapy. Endocrine therapy with fulvestrant prevents growth of hormone receptor positive breast cancer by blocking stimulation of tumor cells by estrogen. Palbociclib is a drug that may stop tumor cells from growing by blocking activity of two closely related enzymes (proteins that help chemical reactions in the body occur), called cyclin dependent kinases 4 and 6 (CDK 4 / 6) which are known to promote tumor cell growth. Monoclonal antibodies, such as avelumab, may help the immune system in detecting and fighting tumor cells. Giving fulvestrant with or without palbociclib and avelumab may work better in treating patients with breast cancer.

  • Ongoing monthly gonadotrophin releasing hormone (GNRH) agonist is required in pre-menopausal women or male participants for at least 4 weeks prior to study entry
  • Participants must have radiological or objective evidence of progression on an endocrine and CDK 4/6 inhibitor regimen in the metastatic setting, and/or relapse/progression during or within 12 months of completion of an endocrine and CDK4/6 inhibitor regimen in the adjuvant setting * Participants must have previously been exposed to CDK4/6 inhibitor therapy in combination with endocrine therapy; exposure to any prior CDK4/6 inhibitor, (including palbociclib, abemaciclib, and ribociclib) is allowed; patients may have a line of endocrine therapy after combination endocrine and CDK4/6 inhibitor exposure * Participants must have remained on prior endocrine and CDK4/6 therapy in the metastatic setting without progression for at least 6 months prior to study entry * It is not mandatory to have a CDK 4/6 inhibitor containing regimen as the most recent treatment * Participants may have had no more than 1 prior line of endocrine and CDK4/6 inhibitor therapy in the metastatic setting
  • Participants may have 0-1 prior lines of cytotoxic chemotherapy in the metastatic setting
  • Prior endocrine therapy in the metastatic setting may include any aromatase inhibitor (AI) or tamoxifen, but may not include prior fulvestrant; in the metastatic setting, 1-2 prior lines of endocrine therapy are allowed
  • Participants may have received radiotherapy for palliative purpose, but must not be experiencing > grade 1 treatment related toxicities, and must have completed treatment > 14 days prior to registration
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-1
  • Absolute neutrophil count >= 1,500/uL
  • Platelets >= 100,000/uL
  • Hemoglobin >= 9 g/dL
  • Total bilirubin =< 1.5 x institutional upper limit of normal (ULN)
  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional ULN, or =< 5 x ULN for subjects with documented metastatic disease to the liver
  • Creatinine =< institutional ULN or creatinine clearance >= 30 mL/min/1.73 m^2 for subjects with creatinine levels above institutional ULN
  • Baseline corrected QT interval (QTc) =< 480 ms
  • Women of childbearing age, women who are made postmenopausal through use of GNRH agonists, and men must agree to use adequate contraception for the duration of protocol treatment and for at least 90 days after the last dose of palbociclib if the risk of contraception exists; adequate contraception is defined as one highly effective non-hormonal form of contraception or two effective forms of non-hormonal contraception by the participant and/or partner * Highly effective non-hormonal contraception ** Methods of birth control which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly are considered highly-effective forms of contraception ** The following non-hormonal methods of contraception are acceptable: *** True abstinence when this is in line with the preferred and usual lifestyle of the participant; (periodic abstinence [e.g., calendar, ovulation, symptothermal post-ovulation methods] and withdrawal are not acceptable methods of contraception) *** Male sterilization (with appropriate post-vasectomy documentation of the absence of sperm in the ejaculate); for female participants, the vasectomized male partner should be the sole partner OR * Effective non-hormonal contraception ** Alternatively two of the following effective forms of contraception may be used instead: *** Placement of non-hormonal intrauterine device (IUD) or intrauterine system (IUS); consideration should be given to the type of device being used, as there is higher failure rates quoted for certain types, e.g., steel or copper wire *** Condom with spermicidal foam/gel/film/cream/suppository *** Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository *** The use of barrier contraceptives should always be supplemented with the use of spermicide; the following should be noted: **** Failure rates indicate that, when used alone, the diaphragm and condom are not highly effective forms of contraception; therefore, the use of additional spermicides does confer additional theoretical contraceptive protection **** However, spermicides alone are ineffective at preventing pregnancy when the whole ejaculate is spilled; therefore, spermicides are not a barrier method of contraception and should not be used alone * It should be noted that two forms of effective contraception are required; a double barrier method is acceptable, which is defined as condom and occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository
  • Premenopausal women must have a negative serum or urine pregnancy test; pregnancy testing does not need to be pursued in female participants who are: * Age > 60 years; or * Age < 60 with intact uterus and amenorrhea for 12 consecutive months or more AND estrogen (estradiol) levels within postmenopausal range; or * Status-post bilateral oophorectomy, total hysterectomy, or bilateral tubal ligation
  • Participant must be able to swallow and retain oral medication
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

  • Participants who have had endocrine, chemotherapy, and/or biologic therapy < 14 days prior to entering the study or those who have not recovered from any prior treatment-related toxicities (must recover to no more than grade 1; alopecia, sensory neuropathy grade =< 2, or other grade =< 2 toxicity not constituting a safety risk based on investigator’s judgment are acceptable)

Trial Objectives and Outline

PRIMARY OBJECTIVES:

I. To evaluate progression-free survival (PFS) using traditional Response Evaluation Criteria in Solid Tumors (RECIST) criteria with the combination of fulvestrant and palbociclib versus (vs.) fulvestrant alone in patients with advanced hormone receptor positive (HR+)/HER2 negative (-) breast cancer that has progressed despite prior CDK4/6 inhibition and endocrine therapy.

SECONDARY OBJECTIVES:

I. To assess the objective response rate (ORR) of fulvestrant + palbociclib vs fulvestrant alone in patients with advanced estrogen receptor (ER)+/HER2- breast cancer that has progressed despite prior CDK4/6 inhibition and endocrine therapy.

II. To assess the PFS and ORR with addition of palbociclib after progression on fulvestrant alone in patients with advanced ER+/HER2- breast cancer that has progressed despite prior CDK4/6 inhibition and endocrine therapy using traditional RECIST criteria.

III. To assess the PFS and ORR for fulvestrant, palbociclib + avelumab vs fulvestrant alone in patients with advanced ER+/HER2- breast cancer that has progressed despite prior CDK4/6 inhibition and endocrine therapy using traditional RECIST criteria.

IV. To assess the PFS and ORR for fulvestrant, palbociclib + avelumab vs fulvestrant + palbociclib in patients with advanced ER+/HER2- breast cancer that has progressed despite prior CDK4/6 inhibition and endocrine therapy using traditional RECIST criteria.

V. Safety and tolerability of all agents.

EXPLORATORY OBJECTIVES:

I. To compare PFS and ORR in the stratified subset of patients where there was exposure to a chemotherapy regimen between initial exposure to CDK4/6 inhibitor and entry on this study.

II. To compare response to therapy with fulvestrant, palbociclib + avelumab using traditional RECIST criteria versus immune-related response criteria (irRC).

III. Assessment of outcomes in predefined molecular subgroups including: ESR mutation, PI3K mutation, Loss of Rb gene and/or function.

IV. To determine the frequency and distribution of Rb loss or loss of function mutation, ESR mutations, and PI3 kinase mutations in tumors with demonstrated resistance to prior CDK4/6 inhibitor and endocrine therapy, as well as response to therapy by arm.

V. To evaluate cyclin E levels in patients who had exposure to a chemotherapy regimen between initial exposure to CDK4/6 inhibitor and entry on this study, versus those who did not receive intervening chemotherapy.

VI. Explore tissue and cell-free deoxyribonucleic acid (cfDNA)-based markers predictive of resistance or response to protocol therapy after prior progression on CDK4/6 and endocrine therapy in ER+ breast cancer, not excluding copy numbers of CCND1 and CDKN2A, proteins (e.g., Ki67, pRb, CCNE1), and ribonucleic acid (RNA) expression (e.g., RB, Cyclin D, E cdk4, cdk6).

VII. Explore tissue and cfDNA-based markers predictive of response to palbociclib in ER+ breast cancer.

VIII. Explore tissue and cfDNA-based markers predictive of response to PD-L1 inhibition in ER+ breast cancer, including immune signature.

OUTLINE: Patients are randomized to 1 of 3 arms.

ARM A: Patients receive fulvestrant intramuscularly (IM) on days 1 and 15 of course 1 and on day 1 of courses thereafter. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients with confirmed disease progression may receive palbociclib as in Arm B.

ARM B: Patients receive fulvestrant as in Arm A. Patients also receive palbociclib orally (PO) once daily (QD) on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM C: Patients receive fulvestrant and palbociclib as in Arm B. Patients also receive avelumab intravenously (IV) over 1 hour once every 14 days. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients in Arms A and B are followed up at 30 days and patients in Arm C are followed up at 90 days. Patients in all arms are then followed up every 12 weeks or 6 months thereafter.
