Study Description

Brief Summary

This is an open-label, two-stage, multi-arm Phase 1 study designed to evaluate the safety and preliminary efficacy of combining niraparib with four standard chemotherapy regimens used to treat TNBC.

Condition or Disease	Intervention/Treatment	Phase
Breast Cancer	Drug: Niraparib Drug: Doxorubicin Drug: Cyclophosphamide Drug: Paclitaxel Drug: Pegfilgrastim Drug: Carboplatin	Phase 1

Detailed Description

Niraparib is an oral, selective poly ADP ribose polymerase (PARP)-1 and PARP-2 inhibitor. A strategy of combining a PARP inhibitor, as a chemopotentiator, with chemotherapy is a promising approach in the treatment of triple-negative breast cancer. This study will evaluate the combination of niraparib with several standard chemotherapy regimens used to treat breast cancer to determine a recommended Stage 2 dose (RS2D) of chemotherapy regimens with niraparib. Stage 1 will be conducted in subjects with metastatic TNBC and will include 4 chemotherapy treatment arms in escalating dose levels (Arm 1: doxorubicin + cyclophosphamide (AC) every 14 days with pegfilgrastim (or biosimilar) for 4 cycles followed by AC every 21 days; Arm 2: AC every 21 days; Arm 3: weekly paclitaxel; Arm 4: weekly paclitaxel + carboplatin every 21 days), each combined with oral daily niraparib. Treatment will continue until disease progression, unacceptable toxicity, or subject withdrawal.Stage 2 will be conducted in subjects with non-metastatic TNBC. Subjects will receive neoadjuvant chemotherapy with either AC every 14 days (Arm 1A) or every 21 days (Arm 2A) at the RS2D of chemotherapy combined with oral daily niraparib from Stage 1. Treatment will continue for 4 cycles.

Inclusion Criteria

Subject must meet all of the following applicable inclusion criteria to participate in this study:

Able to understand and willing to provide written informed consent and HIPAA authorization for release of personal health information. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
Male or female and age ≥ 18 years at the time of consent.
ECOG Performance Status of 0, 1 or 2 (Stage 1), or 0-1 (Stage 2) within 14 days prior to day 1 of treatment.
Histologically or cytologically confirmed hormone receptor negative tumor (estrogen and progesterone) on pathology immunohistochemistry (IHC) assessment defined as <10% staining and HER2-negative, non-overexpressing defined by an IHC 0 or 1+ or fluorescence in-situ hybridization (FISH) HER2:CEP17 ratio < 2.0 with an average HER2 gene copy number of <4 signals/nucleus, and:

Stage 1 (metastatic):

Measurable (by RECIST v1.1) or evaluable lesions

Stage 2 (non-metastatic, treatment naïve, with no prior excisional biopsy/lumpectomy/LND staging):

Primary tumor size ≥ 2 cm by at least one radiographic or clinical measurement. NOTE: this requirement does not apply to subjects with inflammatory TNBC.
Clinical stage at presentation: cT1c-cT4, cN0-cN3
Tumor tissue:

Stage 1:

Willing to provide tumor tissue for research purposes. Fresh biopsy of metastatic lesion prior to day 1 of treatment preferred if feasible. If fresh biopsy of metastatic lesion is not feasible, fresh biopsy can be obtained from the primary tumor site (i.e. breast). Tumor tissue from bone metastases is not acceptable. If fresh biopsy from metastatic tumor or primary tumor site is not possible, archival tumor tissue (formalin-fixed paraffin embedded [FFPE] or tumor block) may be used as long as it is from within 12 months of study entry. NOTE: If tissue is not available within required timeframe (i.e., either fresh or archival) subject will still be eligible for trial.

Stage 2:

Willing to undergo fresh biopsy of the primary tumor prior to day 1 of treatment for research purposes (breast is preferred; lymph node is acceptable). If not clinically feasible, then provide archived tumor tissue (FFPE or tumor block) of the primary tumor within 12 months of study entry. If archived tissue will be submitted rather than fresh biopsy, the archived tissue must be assessed and documented by pathology to ensure adequate tumor is present for correlative analysis. NOTE: For subjects who do not have archival tumor tissue available within required timeframe or if archival tissue insufficient, a pre-treatment core biopsy of the primary breast tumor must be obtained. If subjects have inflammatory breast cancer and a core biopsy is not possible, consideration can be given to obtain a skin punch biopsy.

Demonstrate adequate organ function as defined in the table below; all screening labs to be obtained within 14 days prior to day 1 of treatment.

Absolute Neutrophil Count (ANC): greater than or equal to 1,000/µL
Platelet Count greater than or equal to 100,000/µL without platelet transfusion within 4 weeks of day 1 of treatment
Hemoglobin (Hgb): greater than or equal to 9 g/dL without red blood cell transfusion within 4 weeks of day 1 of treatment
Serum creatinine (SCr): less than or equal to 1.5 × upper limit of normal (ULN)

For subjects anticipated to receive anthracyclines, adequate cardiac function as defined by ≥50% Left Ventricular Ejection Fraction (LVEF) by ECHO or MUGA within 28 days prior to day 1 of treatment.
Females of childbearing potential (FCBP) must have a negative serum pregnancy test within 7 days prior to day 1 of treatment and documented. NOTE: Females are considered of childbearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral salpingectomy, or bilateral oophorectomy) or are postmenopausal (>45 years of age and at least 12 consecutive months with no menses without an alternative medical cause).
FCBP must be willing to use a highly effective contraceptive method (i.e., highly effective achieves a failure rate of <1% per year when used consistently and correctly) or a combination method from the time of informed consent until 30 days after treatment discontinuation. Contraceptive methods with low user dependency are preferable but not required.

Acceptable methods of contraception (highly effective) are:

Single method (one of the following is acceptable):

Non-hormonal Intrauterine device (IUD)
Vasectomy of a female subject's partner
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments.

Combination method (requires use of two of the following):

Diaphragm with spermicide (Cannot be used in conjunction with cervical cap/spermicide)
Cervical cap with spermicide (nulliparous women only)
Contraceptive sponge with spermicide (nulliparous women only)
Male condom or female condom (cannot be used together) with spermicide

Male subjects with female partners who are of child-bearing potential, should use a highly effective method of contraception during niraparib therapy and for 90 days after receiving the last dose of niraparib.
Subjects must agree to not donate blood for 90 days after receiving the last dose of niraparib.
Female subjects must agree to not breastfeed during the study or for 30 days after the last dose of study treatment and male subjects must not donate sperm during niraparib therapy and for 90 days after receiving the last dose of niraparib.
As determined by the enrolling physician, ability of the subject to understand and comply with study procedures for the entire length of the study.
Ability to swallow oral medications.

Stage 1 Exclusion Criteria

Subjects meeting any of the criteria below may not participate in Stage 1 of the study:
