简要总结
Evaluating the efficacy and safety of niraparib and Tumor-Treating Fields (TTFields) in recurrent glioblastoma (GBM).
详细描述
Tumor-treating fields (TTFields) causes downregulation of BRCA1 signaling and reduced deoxyribonucleic acid (DNA) double-strand break repair capacity. Tumors that are deficient in the homologous recombination DNA damage repair pathway are highly sensitive to blockade of the repair of single strand DNA breaks via poly-ADP ribose polymerase (PARP) inhibition. This is a study of niraparib, a PARP inhibitor, in combination with tumor-treating fields for recurrent glioblastoma. We hypothesize that tumor-treating fields will induce a state of "BRCAness" in the glioma tumor cells, thus sensitizing them to PARP inhibition and resulting in tumor cell death.

- •Tumor O-6-methylguanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT) methylation status must be available from any prior GBM tumor specimen.
- •Patients must have measurable contrast-enhancing disease (defined by at least 1cm x 1cm) by magnetic resonance imaging (MRI) imaging within 28 days of starting study treatment.
- •Patients may have had treatment for an unlimited number of prior relapses.
- •Patients must have recovered from severe toxicity of prior therapy.
- •Patients must be able to swallow oral medications.
- •Karnofsky performance status >=
- •Life expectancy >3 months.
- •Adequate hematologic parameters.
- •Adequate hepatic function within 7 days prior to start of study treatment.
- •Adequate renal function within 7 days prior to start of study treatment.
- •Reproductive Status
- •Women - negative serum or urine pregnancy test
- •Men and Women - must agree to an adequate method to avoid pregnancy
- •Participant must agree to not donate blood during the study or for 90 days after the last dose of niraparib.
- •Participant must, in the opinion of the Investigator, be able to comply with study procedures, including use of the Optune device.
- •Cohort B (surgical) patients only: patients must be undergoing surgery that is clinically indicated as determined by their care providers.
- •Cohort B (surgical) patients only: patients must have a tumor tissue form indicating availability of archived tissue from a previous surgery for glioblastoma.
- •Patients must be able to understand the study procedures and agree to participate in the study by providing written informed consent (or have legally authorized representative sign on patient's behalf if patient physically unable to sign consent due to neurologic deficit).
排除标准
- •Age < 22 years.
- •Prior treatment with tumor-treating fields therapy (Optune) within the past 6 months.
- •Prior treatment with a PARP inhibitor.
- •Known history or current diagnosis of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML).

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, or any psychiatric disorder that prohibits obtaining informed consent.

- •Participant must not be simultaneously enrolled in any interventional clinical trial.
研究组 & 干预措施
Cohort A
Cohort A is for subjects with recurrent glioblastoma who do not have clinical indication for surgical resection of the recurrent tumor. Subjects in Cohort A will initiate and continue TTFields therapy for 5-7 days prior to starting niraparib.
干预措施: Niraparib (Drug)

干预措施: Optune (Device)
Cohort B
Cohort B is for subjects with recurrent glioblastoma who have a clinical indication for surgical resection of the recurrent tumor. Subjects in Cohort B will receive TTFields for 5-7 days prior to planned surgical resection, undergo surgical resection, resume TTFields postoperatively, and initiate niraparib 5- 7 days after starting TTFields postoperatively.

结局指标
主要结局
Disease control, defined as achievement of either CR, PR, or SD, as defined by modified Response Assessment in Neuro-Oncology (mRANO) criteria.
时间窗: When termination of the study or 5 years after removal from protocol therapy, whichever occurs first.
Complete response (CR) is seen as the disappearance of all enhancing measurable and non-measurable disease sustained for at least 4 weeks. Partial response (PR) is ≥50% decrease in sum of products of perpendicular diameters or ≥65% decrease in total volume of all measurable enhancing lesions compared with baseline, sustained for at least 4 weeks. Stable disease (SD), must be present on two consecutive MRI scans, with the 2nd/confirmatory MRI performed at least 16 weeks after starting treatment.
次要结局

- Duration of disease control.(When termination of the study or 5 years after removal from protocol therapy, whichever occurs first.)
