- Histologically-confirmed HER2-negative localized breast cancer by core biopsy.
- Primary operable, non-metastatic invasive carcinoma of the breast, confirmed histologically by core biopsy. Fine-needle aspiration is not sufficient. Incisional biopsy is not allowed. In participants with multifocal and/or multicentric, the largest lesion should be measured. Both unilateral and bilateral breast cancer are allowed.

iii) Has undergone post hysterectomy, bilateral oophorectomy, or tubal ligation. Documented hysterectomy, oophorectomy or tubal ligation must be confirmed in the medical records, otherwise the participant must be willing to use 2 adequate barrier methods throughout the study starting from the screening visit through 180 days after the last dose of study drug.

Exclusion Criteria:

- Known evidence of distant metastasis. Staging studies are not required. The decision to pursue staging studies is at the discretion of the treating clinician, based on the participant's clinical and pathological findings consistent with standard guidelines.

- Major surgery within 3 weeks of starting the study or participant has not recovered from any effects of any major surgery.
- Poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 90 days) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, uncontrolled hypertension, active uncontrolled coagulopathy, bleeding disorder, or any psychiatric disorder that prohibits obtaining informed consent.
- History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study drug, or is not in the best interest of the participant to participate.
- Participant is pregnant or breastfeeding, or expecting to conceive children within the projected duration of the study drug or within the 180-day period after the last dose of study drug.
- Immunocompromised participants.
- Known active hepatic disease (Hepatitis B or C).
- Prior treatment with a known PARP inhibitor.
- Other active malignancy that warrants systemic therapy.
- Known history of myelodysplastic syndromes (MDS) or Acute myeloid leukemia (AML).

Intervento / Trattamento |
---|---|
Sperimentale: Participants with HER2-negative and BRCAmut breast cancer
Participants with HER2-negative and BRCAmut localized breast cancer (primary tumor >=1 cm) will receive niraparib (200 mg PO).
|
Niraparib is a potent, orally active, highly selective poly adenosine diphosphate ([ADP]-ribose) polymerase 1 (PARP1) and PARP2 inhibitor.
It will be supplied as 100 mg capsules and will be administered at starting dose of 200 mg PO daily throughout 28 days for 2 cycles (each cycle is 28 days), with the potential for an additional 4 cycles (maximum total of 6 cycles) at the assigned dose and schedule.

Misura Descrizione |
Lasso di tempo |
---|---|---|
Percentage of Participants With Tumor Response Measured by Breast MRI
Lasso di tempo: At 2 months
|
Tumor response measured by breast MRI is defined as >=30 percent (%) reduction of tumor volume from Baseline based on primary lesion after niraparib treatment without any new lesion development.
Tumor volume was calculated as (length × width × height × pi [π])/6.
Responses were assessed as Clinical complete response (CR): A complete disappearance of all tumor signs in the breast as assessed by imaging test.
Clinical partial response (PR): A reduction in the tumor volume of the primary tumor size by >=30% assessed by palpation or imaging test.
Clinical stable disease (SD): No significant change in tumor volume during treatment.
Clinical progressive disease (cPD): The development of new, previously undetected lesions, or an estimated increase in the size of the primary lesion by greater than 20%.
Percentage of participants with tumor response and its 95 percent confidence interval (CI) has been presented.
The 95% CI was the binomial exact CI based on Clopper-Pearson method.

Misura Descrizione |
Lasso di tempo |
---|---|---|
Percentage of Participants With Pathological Complete Response (pCR)
Lasso di tempo: Up to 1 year
|
pCR is defined as ypT0/Tis ypN0 by receipt of pre-operative chemotherapy (Yes versus No).
Following neoadjuvant therapy, pathological staging is recorded using the 'yp' designation.
ypT0/Tis ypN0 is the absence of invasive cancer in the breast and axillary nodes.
pCR is defined as the absence of residual invasive cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy (i.e., ypT0/Tis ypN0 in the current American Joint Committee on Cancer [AJCC] staging system).
Percentage of participants with pCR rate its 95 percent CI has been presented.
CI was based on binomial exact CI.

Percentage of Participants With Tumor Response as Measured by Breast Ultrasound
Lasso di tempo: Up to 6 months
|
Tumor response rate was based on the change in tumor volume as measured by breast ultrasound; a response was considered >=30 percent reduction of tumor volume from Baseline without any new lesion development.
Tumor volume was calculated as (length × width × height × π)/6.
Percentage of participants with tumor response and its 95 percent CI has been presented.
CI was based on binomial exact CI.

Percent Change From Baseline in Tumor Volume Measured by Ultrasound
Lasso di tempo: Baseline and up to 6 months
|
Percentage change in tumor volume from Baseline was measured using ultrasound.
Baseline was defined as the most recent measurement prior to the first administration of niraparib.
Tumor volume was calculated as (length × width × height × π)/6.
The percentage reduction in tumor volume was set as 99% if the tumor becomes too small to measure at the post-baseline visit.
Percent change from Baseline was defined as greatest change in volume, derived from all available cycles of niraparib (range from cycle 2 to 6) and multiplied by 100.

Baseline and up to 6 months
|
Percent Change From Baseline in Tumor Volume Measured by MRI
Lasso di tempo: Baseline and at 2 months
|
Percentage change in tumor volume from Baseline after 2 months of niraparib treatment was measured using MRI.
Baseline was defined as the most recent measurement prior to the first administration of niraparib.
Tumor volume was calculated as (length × width × height × π)/6.
The percentage reduction in tumor volume was set as 99% if the tumor becomes too small to measure at the post-baseline visit.
Percent change from Baseline was defined as value of post Baseline minus Baseline value and multiplied by 100.

Baseline and at 2 months
|
Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), Treatment Discontinuations and Dose Reductions Due to Adverse Events (AEs)
Lasso di tempo: Up to 1 year
|
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment.
An SAE is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or an important medical event.
A TEAE is any event that was not present prior to the initiation of study treatment or any event already present that worsens in either intensity or frequency following exposure to study treatment.
