Niraparib in Combination With Trastuzumab in Metastatic HER2+ Breast Cancer

December 27, 2023 updated by: Erica Stringer-Reasor, University of Alabama at Birmingham

A Phase 1b/2 Study of the PARP Inhibitor Niraparib in Combination With Trastuzumab in Patients With Metastatic HER2+ Breast Cancer

The human epidermal growth factor receptor 2 (HER2) regulates cell growth and survival. Approximately 15-20% of all breast cancers are HER2-positive, which are an aggressive and fast-growing subtype of breast cancer. This study will evaluate a new treatment using a potent Poly polymerase (PARP) inhibitor known as Niraparib. Niraparib will be combined with trastuzumab, a HER2-targeted agent, to evaluate the safety and tolerability in patients with metastatic HER2 positive breast cancer. It is anticipated that the combination of drugs will improve survival and have few side effects.

Detailed Description

Treatment will be administered on an outpatient basis. All patients in the phase 1 and 2 portion of the study will receive Niraparib by mouth on days 1-21 of each 21 day cycle as well as trastuzumab intravenously (IV) on day 1 of each cycle. Blood and tissue will be collected at pre-specified times to enable pharmacokinetic, biomarker, and toxicity studies. The drug dosage will then be determined for the phase 2 portion at a dose limiting level. Following treatment, patients will be followed every 6 weeks for 6 months until disease progression or an unacceptable adverse event.

    • total bilirubin ≤ institutional upper limit of normal (ULN)
    • aspartate aminotransferase (AST)/alanine aminotransferase (ALT) 5 ≤ X institutional ULN
    • creatinine ≤ institutional ULN OR creatinine clearance ≥ 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.
  • Baseline left ventricular ejection fraction (LVEF) ≥ 50% measured by echocardiogram (preferred) or multigated acquisition (MUGA) scans.

  • Female patients of childbearing potential must be willing to use one highly effective form of hormonal contraception or two effective forms of nonhormonal contraception.

  • Contraception must continue for the duration of study treatment and for 7 months after the last dose of study treatment. The above contraception is not a requirement in the case of any of the following:

    • The patient, or partner of the patient, is surgically sterilized.
    • The female patient is >45 years of age and is postmenopausal (has not menstruated for at least 12 consecutive months
    • The patient truly abstains from sexual activity and when this is the preferred option to avoid conception and contraception and/or usual lifestyle of the patient.

Exclusion Criteria:

  • Metastatic breast cancer patients who are HER2 positive and have NOT progressed on at least one prior HER2-targeted therapies for metastatic disease
  • Patients who have not recovered from CTCAE, v. 4.03 grade 2 or higher toxicities of prior therapy to the point that they would be appropriate for re-dosing will be ineligible for study treatment. Subjects receiving weekly therapy must have a washout period from prior chemotherapy of as least one week. Washout period for chemotherapy administered every 2, 3, or 4 weeks will be 2, 3, and 4 weeks respectively, provided subject has recovered from toxicities of prior therapy such that retreatment is appropriate.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Phase 1: Dose-limiting toxicity (DLT)
Time Frame: Baseline to 6 weeks
A DLT is defined as hematological events > or equal to grade 3 leukopenia, anemia, and thrombocytopenia and also non-hematological events > or equal to grade 3 fatigue, nausea, constipation, vomiting, or diarrhea.
Baseline to 6 weeks
Phase 2: Objective Response Rate
Time Frame: Baseline up to 100 weeks
Response and progression of disease will be evaluated using the international criteria proposed by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 Committee.
Baseline up to 100 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of adverse events
Time Frame: Baseline up to 100 weeks
Toxicities will be graded using the Common Terminology Criteria for Adverse Events (CTCAE) v. 4.03.
Baseline up to 100 weeks
Progression-free survival
Time Frame: Baseline to the date of first documented progression to date of death from any cause, whichever comes first, assessed up to 100 months
The RECIST v. 1.1 criteria will be used to evaluate progression-free survival as well as CT and MRI scans. Progression is indicative of existing target and non-target lesions.

Phase 1: Niraparib levels
Time Frame: Baseline to 25 days
Plasma niraparib levels will be assessed at specific time points in participants blood during cycle 2 treatment in Phase I patients only.
