Talazoparib - Carboplatin for Recurrent High-grade Glioma With DDRd
Hong Kong33 participantsStarted 2021-01-01
Plain-language summary
In view of the strong biological rationale of employing PARP inhibition in high grade glioma, the current study purposes testing of talazoparib in a biomarker-enriched group of glioma. Carboplatin will be added to sensitize the tumor to PARP inhibition, and low dose radiation therapy will be applied to increase talazoparib drug penetration through blood-brain barrier. The goal is to estimate the effect size of such combinational treatment approach in recurrent high-grade glioma with DNA damage repair deficiency (dDDR)

Inclusion criteria
. Histopathologically proven diagnosis of WHO grade 3-4 glioma
. Tumor with one or more putatively pathogenic mutations or homozygous deletion in the genes associated with DDR or genomic instability, as listed below, will be eligible for the study. Genetic analysis on tumor tissue should be performed with next-generation-sequencing (NGS) based analysis to screen for the following genomic aberrations, which included,
. IDH mutation
. PTEN mutation
. "BRCAness" signature (ATM, ATR, BAP1, BRCA1, BRCA2, CDK12, CHEK1, CHEK2, FANCA, FANCC, FANCD2, FANCE, FANCF, PALB2, NGS1, WRN, RAD50, RAD51B, RAD51C, RAD51D, MRE11A, BLM, BRIP1) The molecular profiling results will be considered eligible for screening only if they are performed in laboratories accredited by the College of American Pathologists (CAP) and certified to meet Clinical Laboratory Improvement Amendments (CLIA).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Patients will be eligible if the original histology was lower-grade glioma and a subsequent diagnosis of glioblastoma or gliosarcoma is made.
. Patients who did not have recent surgery for their glioblastoma must have shown unequivocal radiographic evidence for tumor progression by contrast-enhanced MRI scan (or CT scan for patients with non-compatible devices) within 21 days prior to registration. Patients who did have surgery with a post-operative contrast-enhanced scan falling outside the 5-week window prior to registration, must have a repeat MRI scan (or CT scan for patients with non-compatible devices) within 21 days prior to registration.
. Patients must have passed an interval of 6 months or greater between completion of prior radiotherapy and registration. If patients have not passed an interval of at least 6 months, they may still be eligible if they meet one or more of the following criteria:
Exclusion criteria
. Prior therapy with PARP inhibitor
. Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 1 year (for example, carcinoma in situ of the breast, oral cavity, or cervix are all permissible).
. Severe, active co-morbidity, defined as follows:
. Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months prior to registration
. Transmural myocardial infarction within the last 6 months prior to registration
. History of stroke or transient ischemic attack within 6 months prior to registration.
. Significant vascular disease (e.g., aortic aneurysm, history of aortic dissection) or clinically
