Fulvestrant Plus Abemaciclib in Women With Advanced Low Grade Serous Carcinoma

• Status: Recruiting
• Trial end date: 2022-05-01
• Target enrollment: 0
• Participant gender: Female

Summary

The goal of this clinical research study is to learn if fulvestrant and abemaciclib can help to control low-grade serous ovarian cancer. The safety of this drug combination will also be studied.

This is an investigational study. Fulvestrant and abemaciclib are both FDA approved and commercially available for the treatment of several types of cancer. Their use in patients with low-grade serous ovarian cancer is investigational. The study doctor can explain how the study drugs are designed to work.

Up to 15 participants will be enrolled in this study. All will take part at MD Anderson.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: M.D. Anderson Cancer Center
• Collaborators: AstraZeneca; Eli Lilly and Company; Pfizer
• Treatments: Estradiol; Fulvestrant; Palbociclib

Criteria

Inclusion Criteria:

1. Patients with clinical or surgical stage III or IV low-grade serous ovarian, primary peritoneal, or fallopian tube carcinomas who in the judgement of the treating physician are unlikely to achieve optimal surgical cytoreduction and have been recommended to receive neoadjuvant therapy.

2. Histological diagnosis must be based on surgical or core biopsy not just fine needle aspiration. Biopsies performed at other institutions must undergo pathology review and confirmation at MD Anderson Cancer Center.

3. Tissue from an archival tissue sample or fresh tissue obtained from a core or excisional biopsy of a tumor lesion.

4. Willingness to provide pre- and post-treatment tissue for translational studies. Pre-treatment fresh frozen tissue must be available for research purposes. This tissue can be collected from preoperative laparoscopy, other diagnostic biopsy, or a research-specific biopsy.

5. Signed informed consent on protocol LAB02-188.

6. Tissue from an archival tissue sample or fresh tissue obtained from a core or excisional biopsy of a tumor lesion.

7. Patients whose clinical biopsies are found to be insufficient for the planned translational studies must be willing to undergo a research biopsy.

8. Patients must have measurable disease by RECIST v1.1. a. Measurable disease is defined at least one lesion that can be accurately measured in at least one dimension (longest dimension to be recorded). Each target lesion must be >20 mm when measured by conventional techniques, including palpation, plain x-ray, CT, and MRI, or >10 mm when measured by spiral CT.

9. Women 18 years of age or older.

10. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1.

11. Abnormal organ function is permitted. However, patients must have: a. absolute neutrophil count >/= 1500/mL b. platelets >/= 100,000/mL c. hemoglobin >/= 9 g/dL d. estimated creatinine clearance >/= 60 ml/min as calculated using the method standard for the institution e. total serum bilirubinaminotransferase (AST/SGOT) and/or alanine aminotransferase (ALT/SGPT)(

12. Resolution of all acute toxic effects of prior therapy or surgical procedures to National Cancer Institute (NCI) CTCAE 4.03 Grade

13. Women of child-bearing potential (intact uterus) MUST have a negative serum or urine human chorionic gonadotropin (HCG) test within 72 hours prior to receiving the first dose of study medication. Patients of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

14. Female patients of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication (Reference Section 7.7). Patients of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

15. Pre/perimenopausal women must be amenable to be treated with goserelin. All patients will be rendered post-menopausal secondary to concomitant administration of goserelin.

16. Ability to understand and willingness to sign informed consent form prior to initiation of the study and any study procedures.

Exclusion Criteria:

1. Patients who are pregnant or breastfeeding.

2. The patient has serious preexisting medical condition(s) that would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea).

3. Current use of food or drugs known to be potent CYP3A4 inhibitors, drugs known to be potent CYP3A4 inducers (for examples, see the Prohibited Concomitant Medications section), and drugs that are known to prolong the QT interval (see Prohibited Concomitant Medications in section 7.6.2).

4. Diagnosis of another malignancy within 3 years, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the cervix.

5. Previous chemotherapy or hormonal therapy for treatment of ovarian cancer.

6. Known Hepatitis B, Hepatitis C or human immunodeficiency virus (HIV) infection.

7. Inability or unwillingness to swallow pills.

8. Active infection requiring intravenous (IV) antibiotics or other uncontrolled intercurrent illness requiring hospitalization.

9. Inability to comply with the study and follow-up procedures.

10. History of any of the following: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), sudden cardiac arrest.

11. Prior hematopoietic stem cell or bone marrow transplantation.

12. Known abnormalities in coagulation such as bleeding diathesis, or treatment with anticoagulants precluding intramuscular injections of fulvestrant or goserelin (if applicable).

13. Known or possible hypersensitivity to fulvestrant, or abemaciclib or any of their excipients.

14. Pre/perimenopausal women with a known hypersensitivity to gnRH (gonadotropin-releasing hormone) agonists.
