Clinical Trial Summary

This randomized pilot early phase I trial studies how well denosumab works in BRCA1/2 mutations carriers scheduled for risk-reducing salpingo-oophorectomy. Denosumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread.

Description:

PRIMARY OBJECTIVE:

I. To compare the effect of denosumab 120 mg subcutaneously every 4 weeks for 1-2 doses to no treatment in the pre-surgical setting on Ki67 proliferation index by immunohistochemistry (IHC) in the fimbrial end of the fallopian tube of premenopausal BRCA1/2 mutation carriers undergoing risk-reducing salpingo-oophorectomy, with or without hysterectomy.

SECONDARY OBJECTIVES:

I. To assess Ki67 proliferation index by immunohistochemistry (IHC) in ovarian surface epithelium and endometrium (if also undergoing a hysterectomy, ~20% of participants) after exposure to denosumab compared to no treatment.

II. To investigate other tissue-based biomarkers in the fimbrial end of the fallopian tube, ovarian surface epithelium, and endometrium (if also undergoing hysterectomy) after exposure to denosumab compared to no treatment, including:

IIa. Apoptosis with cleaved caspase-3 by IHC. IIb. Receptor activator of NF-KB (RANK) and RANK ligand (RANKL) expression by IHC.

IIc. Estrogen receptor (ER) and progesterone receptor (PR) expression by IHC. IId. CD44 and p53 expression by IHC. IIe. Signal transducer and activator of transcription 3 (STAT3) and phosphorylated-STAT3 (pSTAT3) expression by IHC.

III. To analyze gene expression profiling in the fimbrial end of the fallopian tube and ovarian surface epithelium after exposure to denosumab compared to no treatment.

IV. To investigate serum biomarkers at baseline (pre-treatment) and time of surgery (post-treatment) with denosumab compared to no treatment, including:

IVa. Progesterone. IVb. Estradiol. IVc. Denosumab drug levels. V. To investigate serial serum C-terminal telopeptide (CTX) levels from baseline (pre-treatment) to time of surgery to 9 months and 12 months after start of intervention with denosumab compared to no treatment.

VI. To monitor safety and adverse effects of denosumab compared to no treatment.

OUTLINE: Patients are randomized 1 of 2 arms.

ARM I: Beginning within 3 days of menstrual cycle, patients receive denosumab subcutaneously (SC) every 4 weeks for 1-2 doses and undergo risk-reducing salpingo-oophorectomy 14-28 days after last dose.

ARM II: Patients receive no treatment for 2-8 weeks and then undergo risk-reducing salpingo-oophorectomy.

After completion of study treatment, patients are followed up at 6, 9, and 12 months.

• Willing to not undergo any other elective surgery procedure with general anesthesia or conscious sedation during the treatment period; the treatment period is completed after the last injection of denosumab is administered

Exclusion Criteria:

• History of ovarian cancer; history of breast cancer or any other malignancy is permitted if last chemotherapy treatment was greater than 6 months prior to registration and participant is not using endocrine therapy

• Previous treatment with denosumab (including Prolia for osteoporosis or Xgeva for bone metastases) or use of bisphosphonate within 3 months of registration to the study

• Participants receiving any other investigational agents

• History of allergic reactions or hypersensitivity attributed to denosumab or any components of denosumab or compounds of similar chemical or biologic composition to denosumab, such as other RANKL inhibitors

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

• Pregnant and breastfeeding women are excluded from this study because denosumab is an agent with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events (AEs) in nursing infants secondary to treatment of the mother with denosumab, breastfeeding should be discontinued if the mother is treated with denosumab; there is no minimum amount of time since pregnancy/breastfeeding required before enrolling into the study; however, the date of delivery, pregnancy termination, or weaning from breastfeeding will be documented on case report forms; female subjects of child bearing potential and not willing to use, in combination with her partner, highly effective contraception during treatment will be excluded

• Use of endocrine therapy (selective estrogen receptor modulator, aromatase inhibitor, gonadotrophin releasing hormone [GnRH] agonist) within 6 months of registration to the study

• Prior history or current evidence of osteonecrosis or osteomyelitis of the jaw, evidence of untreated local gum or oral infection, or non-healed dental or oral surgery

• Active dental or jaw conditions which require oral surgery/dental procedures, including tooth extraction within 6 months of registration to the study; dental fillings are permitted within 6 months of study registration

• Other risk factors for the development of osteonecrosis of the jaw (ONJ) including poor oral hygiene, use of a dental appliance, immunosuppressive therapy, treatment with angiogenesis inhibitors, systemic corticosteroids, diabetes, or gingival infections

• Known sensitivity to any of the products to be administered during the study (e.g., calcium or vitamin D)

• Known serious infections, including a history of active hepatitis B, hepatitis C, or human immunodeficiency virus (HIV); screening for these infections is not required for study enrollment

• Hypocalcemia (serum calcium or albumin adjusted calcium < 8.0 mg/dL) or renal dysfunction (creatinine clearance < 30 mL/min)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Ki67 Proliferation Index Fallopian Tube Fimbrial Epithelial Cells	Will be assessed using immunohistochemistry (IHC). Quantitative measures of the expression of Ki67 based upon percentage of positive cells will be scored by a pathologist blinded to treatment assignment. In order to evaluate the difference of Ki67 expression between the two arms, 2-sample t-test will be considered.	Up to 12 months
Secondary	Ki67 Proliferation Index in Ovarian Surface Epithelium and Endometrium	Will be assessed using IHC. In order to evaluate the difference of Ki67 expression between the two arms, 2-sample t-test will be considered.	Up to 12 months
Secondary	Other Tissue-based Biomarkers in the Fimbrial End of the Fallopian Tube, Ovarian Surface Epithelium, and Endometrium	Will be assessed using IHC. Including: apoptosis with cleaved caspase-3 (IHC), RANK/RANKL (IHC), estrogen receptor (ER)/progesterone receptor (PR) (IHC), CD44 and p53 (IHC), and STAT3 and pSTAT3 (IHC). Values of tissue-based biomarkers measurements such as tissue Ki67 proliferation index, serum progesterone, etc., which are continuous variables, will be summarized by descriptive statistics including mean, standard deviation, median and range. For tissue biomarkers, linear regression models will be employed to investigate the association of treatment while adjusting for possible confounders (i.e., age, race, etc.). Normality, homoscedasticity, independence of errors, and lack of multicollinearity in the covariates will be evaluated; if needed, proper transformation will be considered.	Up to 12 months
Secondary	Gene Expression Profiling of RANK, Cell Proliferation, Cell Cycle Progression, and Inflammation Pathways	For gene expression profiling analysis, nSolver Analysis Software (nanoString Technologies, Washington [WA]) will be used. Geometric mean is used for calculation of normalization factors. Student's t test is used to calculate differential expression.	Up to 12 months
Secondary	Serum Biomarkers Including Progesterone, Estradiol, and Denosumab Drug Levels	Values of serum biomarkers measurements such as tissue Ki67 proliferation index, serum progesterone, etc., which are continuous variables, will be summarized by descriptive statistics including mean, standard deviation, median and range.	Up to time of surgery
Secondary	Change in Serial Serum C-terminal Telopeptide Levels	2-sample t-test may be applied to evaluate any change in serum biomarkers from baseline to after intervention. To investigate the overall changes in serum biomarkers, a linear mixed model that accommodates intra-participant correlation due to repeated measurements will be utilized adjusting for any potential covariates.	Baseline up to 12 months after start of intervention
Secondary	Toxicity Profile and Frequency of Adverse Effects in Premenopausal BRCA1/2 Mutation Carriers	Categorical variables, such as adverse events, will be summarized by frequency and proportion.	Up to 12 months after start of treatment
