Local, Targeted Therapy With Alpha Emitter [225Ac]Ac-DOTA-SP (TAT) In Newly Diagnosed Glioma (WHO G3-G4)

Brain tumors account for 1.35% of all cancers and cause 2.2% of cancer-related deaths. Gliomas are the most common type, comprising 40-90% of central nervous system tumors in different age groups. The incidence of malignant gliomas is approximately 0.5-2 per 100,000 people annually. Standard treatments include surgical resection, radiotherapy, and chemotherapy, yet overall survival remains low, typically 1-3 years post-diagnosis. The study highlights the pressing need for novel treatment strategies, particularly given the infiltrative nature of gliomas and the potential for targeted therapies using neuropeptides.The aim of this study is to assess the efficacy and safety of local targeted therapy with \[225Ac\]Ac-DOTA-SP in newly diagnosed glioblastoma following standard treatment.It is an interventional study without a control group, initiated by the researcher. Patients included are aged 18-80 with WHO G3-G4 glioma post-first-line treatment, not requiring immediate surgery and meeting specific MRI criteria.Patients will receive a maximum of six cycles of \[225Ac\]Ac-DOTA-SP, involving pre-treatment assessments, local administration of the agent after ensuring catheter patency, and continuous monitoring. Blood tests and neurological evaluations will be performed regularly.Outcome will be assessed by measuring overall survival (OS) and progression-free survival (PFS). The study anticipates improvements in both OS and PFS when compared to current treatments, contributing to critical insights into targeted alpha therapy's effectiveness in glioblastoma.Treatment with \[225Ac\]Ac-DOTA-SP previously indicated few significant side effects, primarily transient issues like seizures. Patients will be closely monitored throughout the study to identify any adverse effects promptly.The estimated study duration is three years, with biological material collected for histopathological and genetic analysis during surgical reoperation.Data will be anonymized to protect patient confidentiality, stored securely, and made available only for the scope of the study.Led by Prof. Przemysław Kunert, the research team includes multiple co-investigators from neurosurgery and nuclear medicine departments.

The aim of the study is to use standardized questionnaires to systematically record influencing factors or predictors for suicidal behavior in glioblastoma patients, particularly with regard to existing depression and anxiety symptoms.

Prophylactic Regimen With Intrathecal Thiotepa in SVZ-positive or Meningeal-risk Glioblastoma

The goal of this clinical trial is to test whether adding preventive intrathecal chemotherapy (thiotepa) to the standard Stupp regimen can lower the risk of leptomeningeal metastasis (LM) and extend survival in patients with newly diagnosed glioblastoma (GBM) whose tumors touch the sub-ventricular zone (SVZ+) or whose surgery accidentally opened the ventricle (VE). The main questions it aims to answer are: Can six weekly intrathecal injections of thiotepa (10 mg) given during chemoradiotherapy increase the chance of remaining free of LM at one year? Does the approach also prolong overall survival and progression-free survival compared with historical controls? Is the combination safe and well-tolerated in this high-risk population? Participants will: Receive maximal safe tumor resection followed by standard radiotherapy (60 Gy/30 fractions) plus daily temozolomide (75 mg/m²). Begin thiotepa injections (via lumbar puncture or Ommaya reservoir) within 1 week of starting radiotherapy, repeated every 7 days for 6 doses. Continue standard adjuvant temozolomide (150-200 mg/m² days 1-5/28) for 6 cycles. Understand that all procedures, toxicities and survival will be tracked for 2 years, with MRI and clinical visits every 4-8 weeks. Provide CSF and blood samples for exploratory biomarkers that may predict response or resistance.

The Feasibility and Efficacy of Dose Timing (Morning vs Evening) of Temozolomide in the Treatment of Glioblastoma

The body's biological functions follow a circadian rhythm, meaning that individual biological functions in the body change over a 24-hour cycle. There is evidence suggesting that the body and cancer cells may react differently to anti-cancer treatment based on the time of day they are exposed. In fact, researchers have already found that giving anti-cancer treatments at a particular time of the day works better in rectal and ovarian cancer. Temozolomide (TMZ) is a chemotherapy pill/capsule commonly given to patients with newly diagnosed glioblastoma after brain surgery and radiation treatment. However, there is no current standard for what time of day TMZ should be taken for the treatment of glioblastoma. In the current study, participants are randomly placed in one of two groups: a morning group and an evening group. Based on this group placement, participants are instructed to either take their TMZ in the morning or in the evening and record the date and time they take their TMZ in a pill diary. Participants will wear a wrist actigraphy device for the first cycle of TMZ. The primary goal of the study is to understand if taking TMZ at a prescribed time of day (morning/evening) is feasible in adults with glioblastoma. This is a pilot trial, and the investigators hypothesize that it will be feasible for glioblastoma patients to take TMZ at the prescribed time of day. The secondary goals of this study are to evaluate participant recruitment, safety, health-related quality of life, biological timing of TMZ delivery, and changes in condition over time. This pilot study will help investigators plan for a larger, pragmatic randomized clinical trial in the future.

A Phase 1b/2a Study to Evaluate the Safety, Pharmacokinetics, and Objective Response of STAR-001 (LP-184) in Combination With Spironolactone in Supratentorial Glioblastoma at First Progression

Approximately 58-68 total subjects will be enrolled. In the first stage, 10 response evaluable subjects (either IDHwt or IDHm Grade 4 astrocytoma) will be enrolled. If 1 or more of the first 10 response evaluable subjects achieve an objective response, 19 further subjects may be accrued in the second stage (for a total of 29 response evaluable subjects). Subjects enrolling in the study will provide fresh (in subjects who undergo a planned tumor resection) or archival (all subjects) tumor tissue sample (at least 10 unstained slides of 5-micron thickness) at screening for retrospective exploratory biomarker analysis and determination of intertumoral PTGR1 levels. STAR-001 (LP-184) will be administered via IV infusion over 30 minutes on Day 1 and Day 8 of each 21-day cycle. The STAR-001 dose for this study is 0.39 mg/kg. Spironolactone will be administered orally on Day (-2), Day (-1), and between 4-8 hours before the STAR-001 infusion on D1 (Day of STAR-001 IV infusion) and on Day 6, Day 7, and between 4-8 hours before the STAR-001 infusion on Day 8 . The spironolactone dose for this study is 100 mg given 3 times prior to STAR-001 infusion.

The trial will evaluate the pharmacokinetics (PK), pharmacodynamics (PD), and safety of BGB-58067. The study is composed of a Phase 0 and expansion Phase 2 component. The Phase 0 primary endpoint will be suppression of symmetric dimethylarginine (SDMA) in tumor tissue measured by immunohistochemistry (IHC). The Phase 2 primary endpoint will be 12-month overall survival rate (OS12). The Phase 0 secondary endpoint will be to characterize the PK of BGB-58067 in tumor tissue, plasma, and cerebrospinal fluid (CSF). The Phase 2 secondary endpoints will include assessing the safety profile of BGB-58067 and evaluating clinical efficacy of BGB 58067 using overall survival (OS) and the 6-month progression-free survival rate (PFS6) estimated by Kaplan-Meier (K-M) methods.

Impact of Androgen Signaling on the Composition of the Immune Microenvironment in Glioblastomas

Glioblastoma (GBM) is the most common and most aggressive primary brain cancer in adults. GBM is more common in men than in women, with a male-to-female ratio of 1.6. Furthermore, being male is associated with a poorer prognosis. These data suggest that sex and/or sexual hormones and more specifically androgens may play a role in the initiation, the growth, and the resistance to treatments of GBM.

Study of an AAV Mediated Dual-Payload Gene Therapy in Patients With High Grade Glioma

The goal of this clinical trial is to first define the Safety and Optimal Biological Dose (OBD) of study drug TGX-007 and to then further investigate the safety and efficacy in patients with newly diagnosed or recurrent Glioblastoma. TGX-007 is a gene therapy drug delivered by a harmless adeno-associated virus (AAV) vector which delivers two combined therapeutic payloads to enable killing of proliferative cells and activation of an anti-tumour immune response. One is herpes simplex virus thymidine kinase (HSV-tk), which converts the pro-drug valaciclovir into an active drug that can kill tumour cells and the other is interleukin 12 (IL-12), which activates the body's immune system to recognise and fight the tumour. Patients newly diagnosed with glioblastoma suitable for standard of care surgery and chemoradiotherapy or patients with recurrent glioblastoma suitable for further surgery may be eligible for the study. Patients will receive TGX-007 by a direct intratumoural injection and will then take the pro-drug valacyclovir orally for up to 21 days before proceeding to standard of care surgery. The study is split into two phases. Phase I will treat patients at different dose levels of TGX-007 to identify the Optimal Biological Dose that will be used to further expand the study into Phase II. Phase II will expand the number of patients treated at the selected OBD to investigate how effective TGX-007 is at treating newly diagnosed and recurrent GBM. Approximately 68 people aged 18-70 will take part in the study.

Clinical Significance of Liquid Biopsy in Brain Tumor Patients: a 5-ALA Guided Approach

Glioblastoma (GBM) is the most common and lethal primary brain tumor. Identifying blood biomarkers that reflect the tumor's status is a major unmet need for optimal clinical management. 5-ALA (5-Aminolevulinic Acid) administration leads to the accumulation of fluorescent Protoporphyrin IX (PpIX) in GBM cells, allowing identification during surgery. This project aims to leverage 5-ALA induced fluorescence to maximize the informational power of plasma liquid biopsy as a tool for diagnosis, post-treatment follow-up, and as a prognostic tool in patients with GBM.

Liquid Biopsy in Glioblastoma Treated With Chemoradiation and an Oxygen Therapeutic

The goal of this sub-study of the RESTORE trial is to identify biomarkers associated with tumor hypoxia, identify biomarkers that differentiate pseudoprogression from true progression, and correlate biomarkers with clinical outcomes.

Limited Target Volume Radiotherapy After Glioblastoma Surgery

Research on radiotherapy target volumes for glioblastoma is increasingly focused on exploring more limited yet effective irradiation fields, aiming to achieve local control while minimizing acute and long-term neurotoxicity. Previous retrospective analysis by investigators revealed that local recurrences of glioblastoma are predominantly confined to a narrow margin around the original lesion: 98.3% of recurrences occurred within 0.5 cm of the original T2-FLAIR abnormality, 94.8% within 1 cm of the original T1-enhanced region. These findings have been cited in the ESTRO-EANO treatment guidelines. Building on this evidence, investigators plan to conduct a single-arm, phase II clinical trial to systematically evaluate the efficacy and safety of a 1 cm radiotherapy target volume in post-operative glioblastoma patients.Eligible patients with glioblastoma who have undergone surgical resection will be selected to receive limited-field radiotherapy. The target volume will be defined based on the postoperative MRI enhancing lesion: a 1 cm margin will be added to form the clinical target volume (CTV), followed by a further 0.3 cm margin to create the planning target volume (PTV). A total dose of 60 Gy will be delivered in 30 fractions (2 Gy per fraction, 5 fractions per week). Concurrent and adjuvant chemotherapy will be administered per standard guidelines. The primary efficacy endpoints are the 6-month progression-free survival rate and the incidence of symptomatic radiation-induced brain necrosis of grade 3 or higher. Secondary endpoints include overall survival, patterns of recurrence, neurocognitive function, and quality of life.

It is a non-interventional, observational study conducted in routine care settings across multiple European sites.

A Study to Evaluate the Safety of a Stem Cell-Based Gene and Cell Therapy in Patients With Newly Diagnosed Glioblastoma

This is a phase I clinical trial evaluating the safety, tolerability, and maximum tolerated dose of MSC11FCD, an investigational allogeneic bone marrow-derived mesenchymal stem cell therapy expressing a suicide gene, in patients with newly diagnosed glioblastoma. The investigational product is administered intratumorally following surgical resection. This study aims to explore whether MSC11FCD can provide a targeted, localized treatment option during the postsurgical period, potentially addressing residual tumor cells and reducing early recurrence.

Study of Low-Intensity Focused Ultrasound in Combination With Immunotherapy in Newly Diagnosed Unmethylated Glioblastoma

This is a phase 1 study for patients with newly diagnosed MGMT unmethylated IDH wild-type glioblastoma utilizing autologous activated T-cells armed with bispecific antibody (EGFR-BATs) that recognize the tumor. The investigators hypothesized that the combination of infusions of EGFR BATs and low-intensity focused ultrasound would induce blood-brain barrier opening and increase the permeability of the adoptive immunotherapy. The investigators will radiolabel the EGFR BATs with 89Zr-oxine for subsequent PET imaging to determine the trafficking and uptake of this approach. There is a concern that several infusions of EGFR BATs before BBB opening could change the immune tumor microenvironment that would not allow a permissive BBB after LIFU. Therefore, Arm A will have two LIFU with BBB opening after the 4th and the 8th infusion, and Arm B will have three LIFU with BBB opening after the 1st, 4th, and 8th infusions. This study will determine the safety and feasibility of the combination of low-intensity focused ultrasound (LIFU) with microbubbles BBB opening and EGFR BATs and the access of the adoptive cell immunotherapy to the tumor microenvironment to inform future studies.

The CCANED-CIPHER Study: Early Cancer Detection and Treatment Response Monitoring Using AI-Based Platelet and Immune Cell Transcriptomic Profiling
