Pre-Radiation Chemotherapy for Newly Diagnosed High-Grade Glioma.

Better treatments are needed for high-grade gliomas (HGG), and new ways of treating this disease should be tested. The investigators want to see if giving medicine before radiation works well. After radiation, MRI scans can be harder to understand because radiation changes how the brain looks on the scan. If new medicines are given before radiation, the scans are easier to read. First, the investigators need to find out if giving chemotherapy early works using a drug we already know can treat gliomas. The investigators will start with temozolomide, which is the only chemotherapy approved by the FDA for HGG. If this approach is successful, the investigators can then test new drugs using this screening method.

A Clinical Study to Improve Brain Function and Quality of Life of Patients With Newly Diagnosed Brain Tumors (Gliomas).

Oligodendrogliomas in the novel edition of the Central Nervous System (CNS) World Health Organization (WHO) classification are now molecularly defined by isocitrate dehydrogenase (IDH)1 or IDH2 mutations and 1p/19q co-deletion. The prognosis of these molecularly defined tumors is to be determined in new series since survival data from older histology-based studies and population-based registries are confounded by the inclusion of 20-70% not molecularly matching subsets. Also, the optimal treatment is a matter of ongoing investigations. An extensive, but safe surgery is associated with improved outcome as is the addition of chemotherapy with procarbazine, CCNU (lomustine), and vincristine (PCV) to the partial brain radiotherapy (RT). However, the exact timing of postsurgical therapy especially for tumors of the WHO grade 2 and acknowledging some variability in grading as well as the choice of chemotherapy, temozolomide instead of PCV (CODEL: NCT00887146 randomizing CNS WHO grade 2 and 3 oligodendrogliomas to chemoradiation(CHRT)therapy with PCV or with temozolomide) or the need for primary radiotherapy RT are subjects of clinical studies (POLCA: NCT02444000 randomizing patients with newly diagnosed CNS WHO grade 3 oligodendrogliomas to standard CHRT with PCV or PCV alone). Given the young age of patients with CNS WHO grade 2 and 3 oligodendrogliomas and the relevant risk of neurocognitive, functional and quality-of-life impairment with the current aggressive standard of care treatment, chemoradiation with PCV, of the tumor located in the brain optimizing care is the major challenge. NOA-18/IMPROVE CODEL aims at improving qualified overall survival (qOS) for adult patients with CNS WHO grade 2 and 3 oligodendrogliomas by randomizing between standard chemoradiation with up to six six-weekly cycles with PCV and six six-weekly cycles with lomustine and temozolomide (CETEG), thereby delaying radiotherapy (RT) and adding the chemoradiotherapy (CHRT) concept at progression after initial radiation-free chemotherapy, allowing for an effective salvage treatment and delaying potentially deleterious side effects. QOS represents a new concept and is defined as OS without functional and/or cognitive and/or quality of life (QOL) deterioration regardless whether tumor progression or toxicity is the main cause.

A Randomized Trial of Delayed Radiotherapy in Patients Low-grade Oligodendrogliomas Requiring a Treatment Other Than Surgery

Because of their prolonged survival, patients with 1p/19q-codeleted low-grade oligodendrogliomas treated with RT + PCV are at risk of neurocognitive deterioration. We make the hypothesis that withholding radiotherapy until tumor progression could reduce the risk of neurocognitive deterioration without impairing overall survival.

Chemotherapy and Radiation Therapy for the Treatment of IDH Wildtype Gliomas or Non-histological (Molecular) Glioblastomas

This phase II trial studies how well temozolomide and radiation therapy work in treating patients with IDH wildtype historically lower grade gliomas or non-histological molecular glioblastomas. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. The goal of this clinical research study is to compare receiving new radiation therapy doses and volumes to the prior standard treatment for patients with historically grade II or grade III IDH wild-type gliomas, which may now be referred to as IDH wildtype molecular glioblastomas at some institutions. Receiving temozolomide in combination with radiation therapy may also help to control the disease.

HOBSCOTCH-CA (HOme-Based Self-management and COgnitive Training CHanges Lives in Brain CAncer)

The purpose of this study is to assess the ability of the home-based intervention, HOBSCOTCH-CA, to improve the quality of life and cognitive function in Service Members, Veterans and civilians who are survivors of brain cancer or a brain tumor (CA participants). This study will also assess the ability of the HOBSCOTCH-CA program to improve quality of life in caregivers of patients with brain cancer/tumor and to reduce caregiver burden. Enrolling with a Caregiver is optional for CA participants. Investigators will compare two groups of CA participants and their Caregiver (enrolling with a Caregiver is optional): one who receives HOBSCOCTCH-CA immediately (Group 1) and another group that will receive HOBSCOTCH-CA (Group 2) after a 3-month waiting period. Participants will be in the study for about 6 months total. HOBSCOTCH-CA involves 45 to 60 minute one on one virtual sessions with a certified Cognitive Coach including a "pre" program session and 8 weekly sessions thereafter. Participants will learn about problem solving therapy and mindfulness or relaxation training. CA participants are asked to do short homework assignments and keep a brief daily diary on a smart phone app. All participants complete study questionnaires or surveys at enrollment, 3 months later and at 6 months (at the end of the study).

Proton Beam or Intensity-Modulated Radiation Therapy in Preserving Brain Function in Patients With IDH Mutant Grade II or III Glioma

This randomized phase II clinical trial studies the side effects and how well proton beam or intensity-modulated radiation therapy works in preserving brain function in patients with IDH mutant grade II or III glioma. Proton beam radiation therapy uses tiny charged particles to deliver radiation directly to the tumor and may cause less damage to normal tissue. Intensity-modulated or photon beam radiation therapy uses high-energy x-ray beams shaped to treat the tumor and may also cause less damage to normal tissue. It is not yet known if proton beam radiation therapy is more effective than photon-based beam intensity-modulated radiation therapy in treating patients with glioma.

PRO-GLIO: PROton Versus Photon Therapy in IDH-mutated Diffuse Grade II and III GLIOmas

Proton therapy is a powerful tool enabling oncologists to spare normal tissue around the target for irradiation much better than what can be achieved with photon irradiation. The infiltrative nature of IDH-mutated grade II and III diffuse glioma, however, renders proton therapy a potential problem. A randomized controlled trial (RCT) is the only option when trying to ensure that chances of long-term survival are not impaired seeking to reduce unwanted late treatment effects. Non-inferiority of proton therapy compared to photon irradiation is the primary endpoint of the RCT. Hence, PRO-GLIO has two main objectives. First, PRO-GLIO will evaluate if proton therapy is safe in patients with IDH-mutated grade II and III diffuse glioma, showing that survival figures at 2 years from radiotherapy are not poorer in the proton arm than in the photon arm. Second, we want to find the true number of patients in need of rehabilitation in both arms, and evaluate if proton therapy conveys a higher QoL than photon irradiation at 2 years from radiotherapy.

Proton Therapy Research Infrastructure- ProTRAIT- Neuro-oncology

The first proton therapy treatments in the Netherlands have taken place in 2018. Due to the physical properties of protons, proton therapy has tremendous potential to reduce the radiation dose to the healthy, tumour-surrounding tissues. In turn, this leads to less radiation-induced complications, and a decrease in the formation of secondary tumours. The Netherlands has spearheaded the development of the model-based approach (MBA) for the selection of patients for proton therapy when applied to prevent radiation-induced complications. In MBA, a pre-treatment in-silico planning study is done, comparing proton and photon treatment plans in each individual patient, to determine (1) whether there is a significant difference in dose in the relevant organs at risk (ΔDose), and (2) whether this dose difference translates into an expected clinical benefit in terms of NormalTissue Complication Probabilities (ΔNTCP). To translate ΔDose into ΔNTCP, NTCP-models are used, which are prediction models describing the relation between dose parameters and the likelihood of radiation-induced complications. The Dutch Society for Radiotherapy and Oncology (NVRO) setup the selection criteria for proton therapy in 2015, taking into account toxicity and NTCP. However, NTCP-models can be affected by changes in the irradiation technique. Therefore, it is paramount to continuously update and validate these NTCP-models in subsequent patient cohorts treated with new techniques. In ProTRAIT, a Findable, Accessible, Interoperable and Reusable (FAIR)data infrastructure for both clinical and 3D image and 3D dose information has been developed and deployed for proton therapy in the Netherlands. It allows for a prospective, standardized, multi-centric data from all Dutch proton and a representative group of photon therapy patients.

Sintilimab (One Anti-PD-1 Antibody) Plus Low-dose Bevacizumab for ctDNAlevel- Relapse and Clinical-relapse Oligodendroglioma

This is an ongoing Phase 2, open-label, single-center, non-randomized study of sintilimab (one anti-PD-1 antibody same as nivolumab approved in China) plus bevacizumab administered in a low dosage schedule in adult (≥ 18 years) participants with a clinical relapse or circulating tumor DNA (ctDNA)-level relapse of Oligodendroglioma(WHO III). This study has three non-comparative study groups. Cohort 1 and Cohort 2 will receive the same study drug sintilimab 200mg and bevacizumab 3mg/kg every 3 weeks. Cohort 3 will take only standard treatment. A stringent three-step non-randomized process will be used to assign participants to one of the study groups. Neither participants nor doctors but the researcher can choose which group participants are in. No one knows if one study group is better or worse than the other. 80 total participants are expected to participate in this study (30 participants in Cohort 1 and Cohort 2). Grouping process: After enrollment, under the standard of care, participants will receive regular tumor in situ fluid (fluid within the surgical cavity, TISF) sampling for ctDNA analysis and recceive regular MRI. The researcher will study the TISF ctDNA and imaging dynamics to determine whether the tumor reaches to ctDNA-level (Cohort 1) or clinical relapse (Cohort 2). At the first step, all timely identified as ctDNA-level relapse tumors will be assigned into the Cohort 1 and receive the study drug immediately, those failed to be timely identified will be assigned into the Cohort 2 and receive the study drug after the clinical relapse. At the second step, once Cohort 1 or Cohort 2 reaches the target number, the new participants will be all assigned into the other Cohort. In the third step, if no CTDNA-level or clinical relapse was observed within 60 months after surgery, patients were assigned to Cohort 3 and further analyzed for prognostic biomarkers compared with Cohort 1 and Cohort 2.

Efficacy of Post-radiation Adjuvant Temozolomide Chemotherapy in Residue Low-grade Glioma

Low-grade glioma (LGG) is a common primary brain tumor in young adults. The infiltrative nature and frequent growth in eloquent area in brain often makes total resection impossible. Until now, no agreement has been achieved on the treatment of LGG without total resection. Post-radiation adjuvant temozolomide (TMZ) is currently the standard of care for high-grade gliomas. Radiotherapy or TMZ is recommended for the treatment of residue low-grade gliomas. However, the efficacy of combined radiotherapy with adjuvant TMZ for residue LGG remains to be defined. In this randomized controlled trial, the investigators will test the hypothesis that radiotherapy with subsequent TMZ chemotherapy is superior to improve the progression-free survival of patients with residue LGG without significant impairment to quality of life compared to radiotherapy alone.
