Niraparib in Tumors Metastatic to the CNS

Genomically Guided Phase II Study to Evaluate the Clinical Benefit of Niraparib in Tumors Metastatic to the CNS

This research is being done to see how effective the drug niraparib is against cancer that has metastasized to the central nervous system (CNS).

• This research study involves the study drug niraparib.

Study Overview

• Status: Recruiting
• Conditions: Metastatic Cancer; Central Nervous System Cancer
• Intervention / Treatment: Drug: Niraparib

Detailed Description

This is a single arm open-label study designed to evaluate the efficacy and safety of niraparib in treating cancer that has metastasized to the central nervous system (CNS).

The U.S. Food and Drug Administration (FDA) has not approved niraparib for cancer metastasized to the central nervous system (CNS) but it has been approved for other uses.

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 associated with your diagnosis from occurring.

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.

Participants will receive the study drug for up to 2 years or until their disease worsens, they have unacceptable side effects, or they meet one of the criteria to be removed from the study. Participants will then be followed every 4 months for up to 2 years.

It is expected that about 20 people will take part in this research study.

GlaxoSmithKline, a pharmaceutical company, is supporting this research study by providing funding for the study, including the study drug.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Participants must have histologically or cytologically confirmed disease from any solid tumor.
• Patients must be asymptomatic or minimally symptomatic from CNS metastases for at least 7 days prior to initiation of study therapy. Minimal symptoms is defined as not requiring escalating doses of steroids or seizure medications for at least 7 days prior to initiation of study therapy.
• Participants must have measurable disease in the CNS, defined as at least one lesion that can be accurately measured in at least one dimension as ≥10 mm.

• Participants must have progressive CNS lesions, as defined by one of the following:

  • Patients may have multiple progressive CNS lesions, some of which have been treated by SRS or surgery. Patients are eligible if they have one or more un-treated (by surgery or SRS) progressive lesions that is measurable.
  • Patients have measurable residual or progressive lesions after surgery.
  • Patients who have had prior WBRT and/or SRS are eligible but there needs to be unequivocal evidence of progression of at least one lesion treated by radiation (e.g. tissue diagnosis). Biopsy can be considered for definitive diagnosis.
  • Patients who have previously been treated with systemic therapy for CNS metastases are eligible.
• Diagnosis of triple negative breast cancer or ovarian cancer, or any cancer histology with the presence of alteration in BRCA1, BRCA2, PARP metabolism, DNA repair pathways and HRD (homologous recombination deficiency) genes in the metastatic site as described in Section 9.2 using a CLIA-certified assay. Specific genetic changes in the HRD signature or DNA repair pathway include mutations in ATM, BAP1, BARD1, BRCA1, BRCA2, BRIP1, MRE11A, NBN, PALB2, RAD50, RAD51B, RAD51C, RAD51D, RAD54B, RAD54L, ATR, XRCC2, and XRCC3.
• Age > 18 years. The toxicity of niraparib in children is unknown.
• ECOG performance status ≤ 2 (Karnofsky ≥ 60, see Appendix A).

• Participants must have normal organ and marrow function as defined below:

  • leukocytes ≥3,000/mcL
  • absolute neutrophil count ≥1,500/mcL
  • platelets ≥100,000/mcL
  • hemoglobin ≥9g/dL
  • total bilirubin total bilirubin < 1.5 x institutional upper limit of normal OR > 1.5 x institutional upper limit of normal allowed if direct bilirubin is within normal range. Patients with Gilberts will be eligible if total bili < 3.
  • AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal
  • creatinine clearance ≥30 mL/min/1.73 m2 using the Cockcrof-Gault equation.
  • baseline QTc <480ms

• Female participant has a negative urine or serum pregnancy test within 72 hours prior to taking study treatment if of childbearing potential and agrees to abstain from activities that could result in pregnancy from screening through 180 days after the last dose of study treatment, or is of nonchildbearing potential. Nonchildbearing potential is defined as follows (by other than medical reasons):

  • ≥45 years of age and has not had menses for >1 year
  • Patients who have been amenorrhoeic for <2 years without history of a hysterectomy and oo phorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
  • Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure, otherwise the patient must be willing to use a highly effective barrier methods throughout the study, starting with the screening visit through 180 days after the last dose of study treatment. See Section 4.4 for a list of acceptable birth control methods. Information must be captured appropriately within the site's source documents.
