- Phase 0 Expansion Arm A: Progression-free survival in participants with demonstrated PK effects
研究概览
简要总结
This is an open-label, multi-center Phase 0 study with an expansion phase that will enroll up to 24 participants with newly-diagnosed glioblastoma and up to 18 recurrent glioma participants with IDH mutation and ATRX loss. The trial will be composed of a Phase 0 component (subdivided into Arm A and B) and a therapeutic expansion phase. Patients with tumors demonstrating a positive PK Response (in Arm A) or a positive PD Response (in Arm B) of the Phase 0 component of the study will graduate to a therapeutic expansion phase that combines therapeutic dosing of niraparib plus standard-of-care fractionated radiotherapy (in Arm A) or niraparib monotherapy (in Arm B) until progression of disease.

If the serum pregnancy test is completed > 7 days from Day 1, a urine pregnancy test will be done to confirm a negative result prior to Day 1 dose administration.
- •For females of reproductive potential: use of highly effective contraception for at least 1 month prior to treatment and agreement to use such a method during study participation and for an additional 6 months after the end of treatment administration.
- •For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner and for an additional 3 months after the end of treatment administration. Avoid sperm donation for duration of the study and for an additional 6 months after the end of treatment administration.
- •Agreement to adhere to Lifestyle Considerations throughout study duration.
- •Participants who received chemotherapy must have recovered (Common Terminology Criteria for Adverse Events [CTCAE] Grade ≤1) from the acute effects of chemotherapy except for residual alopecia or Grade 2 peripheral neuropathy prior to Day
- •A washout period of at least 21 days is required between last chemotherapy and Day
- •Females of child-bearing potential must agree not to breastfeed starting at screening, throughout the study period and for 6 months after final study drug administration.
- •Participant has normal blood pressure or adequately treated and controlled hypertension (Defined as systolic BP ≤140 mmHg and diastolic BP ≤90 mmHg).
- •Participant has adequate bone marrow and organ function as defined by the following laboratory values (as assessed by the local laboratory for eligibility):
- •Adequate Bone Marrow Function:
- •Absolute Neutrophil Count ≥1,500/mcL
- •Platelets (at time of surgery) ≥100,000/mcL
- •Hemoglobin ≥9.0 g/dL. Participants may receive erythrocyte transfusions to achieve this hemoglobin level at the discretion of the investigator. Initial treatment must not begin earlier than the day after the erythrocyte transfusion.
- •Adequate Hepatic Function:
- •Total Bilirubin ≤1.5 X ULN. Participants with Gilbert's syndrome with a total bilirubin ≤2.0 times ULN and direct bilirubin within normal limits are permitted.
- •AST(SGOT) ≤2.5 X institutional ULN
- •ALT(SGPT) ≤2.5 X institutional ULN
- •Adequate Renal Function:
- •Estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73 m2 by Chronic Disease Epidemiology Collaboration (CKD-EPI) equation
- •INR ≤1.5 x ULN
排除标准
- •Current use of coumarin-derived anticoagulant for treatment, prophylaxis or otherwise, that cannot be discontinued prior to surgery. Therapy with heparin, low molecular weight heparin (LMWH) or fondaparinux is allowed.
- •Pregnancy or lactation.
- •Known allergic reactions to components of the niraparib tablet, including FD&C Yellow No. 5..
- •Active infection or fever >38.5°C requiring systemic antibiotic, antifungal or antiviral therapy within 4 weeks of Day
- •Known to have active (acute or chronic) or uncontrolled severe infection, liver disease such as cirrhosis, decompensated liver disease, and active and chronic hepatitis as determined by the investigator.
- •Known active systemic bacterial infection (requiring intravenous [IV] antibiotics at time of initiating study treatment), fungal infection, or detectable viral infection (such as known human immunodeficiency virus positivity or with known active hepatitis B or C [for example, hepatitis B surface antigen positive]. Screening is not required for enrollment.
- •Any of the following cardiovascular criteria:
- •Current evidence of cardiac ischemia
- •Current symptomatic pulmonary embolism
- •Acute myocardial infarction ≤ 6 months prior to Day 1
- •Heart failure of New York Heart Association Classification III or IV ≤ 6 months prior to Day 1 (Appendix 13.2)
- •Grade ≥ 2 ventricular arrhythmia ≤ 6 months prior to Day 1
- •Cerebral vascular accident (CVA) or transient ischemic attack (TIA) ≤ 6 months prior to Day 1
- •Participant has myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of MDS/AML.
- •Participant has serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment], history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea).

研究组 & 干预措施
Arm A: Presumed Newly-Diagnosed glioblastoma
Participants undergoing resection for a presumed newly-diagnosed glioblastoma (WHO grade 4) will be treated with niraparib for 4 days prior to surgical resection. Participants who proceed to the therapeutic expansion phase of this study will receive niraparib in combination with radiation (60 Gy over 6-7 weeks, as per standard of care). Following radiotherapy, eligible study participants may receive niraparib maintenance treatment.
