Study Arms (1)

Niraparib

EXPERIMENTAL

* Niraparib will be administered orally on a daily basis * Radiation Therapy will be administered concurrently with Niraparib

Drug: NiraparibRadiation: Radiation Therapy

Interventions

Niraparib is a type of drug called a "PARP inhibitor", which blocks DNA (the genetic material of cells) damage from being repaired or may prevent damage from occurring in the first place. In cancer treatment, inhibiting PARP may help kill cancer cells by not allowing the cancer cells to repair its DNA damage or prevent DNA damage from occurring.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males or Females, ≥ 18 years of age.
  • Non-metastatic, histologically or cytologically-confirmed TNBC (defined as ER \<1%, PR \<1%, her-2-neu 0-1+ by IHC or FISH-negative or as per MD discretion).
  • Definitive surgical treatment with breast-conserving surgery or mastectomy and axillary lymph node evaluation.
  • Plans for receipt of postoperative radiation therapy to the breast/chest wall +/- regional nodes
  • Residual invasive disease after NAC (any size), or at least 1.0 cm in patients who do not receive NAC and undergo surgery first.
  • ECOG Performance status ≤ 1.
  • Willingness to discontinue any cytotoxic chemotherapeutic agents, immunotherapy and biologic therapy at least 2 weeks prior to the start of RT.
  • Adequate organ function (assessed within 30 days prior to initiation of protocol treatment, unless otherwise indicated) as follows:
  • Hematology
  • Absolute Neutrophil Count (ANC) ≥1500/mm3
  • Platelet Count ≥100,000/mm3
  • Hemoglobin ≥9.0 g/dL
  • Renal Function
  • Creatinine Serum ≤ 1.5 mg/dL or
  • Creatinine Clearance ≥ 45 mL/mina
  • +21 more criteria

You may not qualify if:

  • Gross residual tumor or positive margins after surgery that is un-excised (excluding positive margins at the chest wall or skin where no additional breast tissue can be removed).
  • pT1aN0 or pT1bN0 (primary tumor size \<1.0 cm) triple negative breast cancer patients who do undergo neoadjuvant chemotherapy and receive surgery followed by +/- adjuvant chemotherapy.
  • Receipt of PARP inhibitor at any time prior to study enrollment.
  • Pregnant or expecting to conceive within the projected duration of the trial, starting with screening visit through 180 days after the last dose of trial treatment.
  • Prior history of radiation therapy to the ipsilateral breast and/or regional nodes is not allowed (prior RT to other sites that was completed ≥ 1 week prior to Day 1 of protocol therapy, or if prior RT encompassed \>20% of the bone marrow it was completed ≥ 2 weeks prior to Day 1 of protocol therapy, is permitted).
  • Major surgery ≤ 3 weeks prior to initiating protocol therapy and participant must have recovered from any surgical effects.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to niraparib, or its components or excipients.
  • Concomitant anti-neoplastic treatment is not allowed during protocol treatment and should be completed at least 2 weeks prior to commencement of protocol treatment, with resolution of associated acute toxicities. Bisphosphonates are permitted without restriction even during protocol treatment.
  • Significant comorbidity: Patients with clinically significant and uncontrolled major disease or disorder that could exacerbate potential toxicities, confound safety assessments, require excluded therapy for management, or limit study compliance.
  • Treatment with investigational therapy within ≤ 4 weeks, or within a time interval less than at least five half-lives of the investigational agent, whichever is shorter, prior to initiating protocol therapy. Patients may not be simultaneously enrolled in any interventional clinical trial.
  • Unresolved toxicity from other agents. Patients with unresolved CTCAE v5 Grade 2 or greater toxicity, with the exception of alopecia and anemia, from prior administration of another investigational drug and/or anti-cancer treatment are not eligible.
  • Known grade 3 or 4 anemia, neutropenia, or thrombocytopenia that persisted \> 4 weeks and was related to the most recent chemotherapy treatment.
  • Participant must not have received a transfusion (platelets or red blood cells) ≤ 4 weeks prior to initiating protocol therapy.
  • Participant must not have received colony-stimulating factors (e.g. granulocyte colony-stimulating factor, granulocyte macrophage colony-stimulating factor, or recombinant erythropoietin) within 4 weeks prior to initiating protocol therapy.
  • Prior malignancy within 5 years of study enrollment.
  • +7 more criteria
