Niraparib/TTFields in GBM

Апстракт
Опис
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.

Состојба или болест
Интервенција / третман
Drug: Niraparib
Device: Optune
Procedure: Cohort B
Фаза
Групи за раце
| Рака | Интервенција / третман |
|---|---|
| Experimental: 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. | |
| Active Comparator: 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. | Procedure: Cohort B Surgery of supratentorial glioblastoma (GBM). |
