About this study
Official title: Randomized, Controlled Trial of Anterior Temporal Lobectomy Versus Gross Total Resection in Newly-diagnosed Temporal Glioblastoma (ATLAS/NOA-29)
The ATLAS/NOA-29 trial is a prospective, multicenter, phase III randomized controlled study evaluating whether anterior temporal lobectomy (ATL), a standardized resection technique adapted from epilepsy surgery, improves clinical outcomes in patients with newly diagnosed glioblastoma of the anterior temporal lobe compared to conventional gross-total resection (GTR). The rationale is based on the concept of glioblastoma as a diffusely connected tumor network, with infiltrative spread extending beyond MRI-detectable tumor margins. ATL offers a reproducible supramarginal resection approach within anatomical boundaries that are routinely respected in epilepsy surgery.
Patients are randomized intraoperatively in a 1:1 ratio following histopathological confirmation via intraoperative frozen section procedure. The trial's primary objective is to demonstrate superiority of ATL in overall survival (OS), while confirming non-inferiority in health-related quality of life (QoL), measured by the global health status scale of the European Organisation for Research and Treatment of Cancer (EORTC) - Quality of Life Questionnaire Core 30 (QLQ-C30). Secondary outcomes include progression-free survival (PFS), seizure control, neurocognitive functioning, and longitudinal assessments of selected EORTC QLQ-C30 and BN20 domains. A total of 178 patients will be enrolled over three years, with a minimum follow-up of three years. An interim safety analysis after inclusion of 57 patients will assess functional outcome differences using the modified Rankin Scale (mRS) at 6 months postoperatively. The study is powered (>80%) to detect a survival benefit assuming a median OS increase from 17 to 27.5 months. If proven superior to GTR, ATL could emerge as the preferred surgical strategy for isolated temporal lobe glioblastoma, offering robust evidence in favor of extending supramarginal resection principles to the broader context of glioblastoma care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Anterior temporal lobectomy (ATL)Procedure or surgery
Patients assigned to the experimental group will undergo an anterior temporal lobectomy (ATL) according to established protocols adapted from epilepsy surgery. ATL is a reproducible and anatomically well-defined procedure routinely performed in patients with pharmacoresistant temporal lobe epilepsy. On the non-dominant hemisphere, the neocortical resection typically extends 6.5 cm posteriorly from the temporal pole, while on the dominant side, the resection length is limited to 4.0 cm, both measured along the superior temporal gyrus and guided by the Sylvian fissure. Language dominance is determined based on handedness, as specified in the inclusion criteria. In most cases, the lateral neocortical segment can be removed en bloc.
The mesial component of ATL encompasses resection of the uncus, amygdala, and the anterior hippocampus, typically including both the head and body. Resection is carried out to the level of the tectal plate or, at minimum, to the lateral mesencephalic sulcus.
Gross Total Resection (GTR)Procedure or surgery
Patients will be surgically treated with GTR in terms of removing 100% of the tumor tissue in gadolinium-enhanced MRI.
| Study group | Role | What they receive |
|---|---|---|
| Gross total resection (GTR) | Active comparator | Complete resection of the contrast-enhancing tumor in Magnetic Resonance Imaging (MRI) Receives: Procedure: Gross Total Resection (GTR) |
| Anterior temporal lobectomy (ATL) | Experimental | Anterior temporal lobectomy Receives: Procedure: Anterior temporal lobectomy (ATL) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall survival
OS in the modified intention to treat (mITT) population of patients with glioblastoma, Central Nervous System (CNS) World Health Organization (WHO) grade 4, Isocitrate Dehydrogenase wild-type (IDHwt)
Measured: From randomization until death or 36 months after recruitment of the last patient
Patient-reported Quality of Life
In case of significant OS differences, the patient-reported QoL domain "global health status" (EORTC QLQ-C30 questionnaire) in the modified intention to treat (mITT) population is the co-primary endpoint. Over-all superiority of ATL requires significantly prolonged OS and non-inferiority regarding the development of the global health status over time in the mITT population.
Measured: From randomization until death or 36 months after recruitment of the last patient
Secondary outcomes (6)
Progression-free survival
Progression is defined as the first documented evidence of progression of disease according to the Response Assessment in Neuro-Oncology 2.0 (RANO 2.0) criteria. Progression will be evaluated using the RANO (Response Assessment in Neuro-Oncology) 2.0. criteria.
Measured: PFS is measured from randomization at the day of surgery until progression or death. PFS will be assessed at the 12-week follow-up visit and at all subsequent visits scheduled at 12-week intervals up to three years.
Neurocognitive Outcome
All patients will undergo testing with the Brain Lesion Tracking Test (BLTT). The test covers all relevant domains of neurocognition-including episodic and semantic memory as well as executive functions-without excluding patients due to neurological impairments such as visual deficits or hemiparesis.
The BLTT includes interlocking word list learning with delayed free recall and recognition, semantic word generation and fluency, phonemic fluency, reverse digit span, and incidental memory, providing a rapid screening of neurocognitive function. Results are categorized into three performance domains: executive functions, episodic memory, and semantic memory. In addition, figural memory is assessed through a visual recognition task involving drawn objects presented on a series of cards.
Measured: Cognitive performance across all domains will be quantitatively assessed at baseline (preoperatively), and at follow-up visits on day 90 (visit 8) and one year after surgery (visit 11).
Karnofsky Performance Scale
Karnofsky Performance Scale (KPS) is an attempt to quantify cancer patients' general well-being and activities of daily life. The KPS ranking runs from 100 to 0, where 100 is "perfect" health and 0 is death.
Measured: KPS will be assessed at baseline, on postoperative day 1, and at follow-up visits on days 3, 14, 30, and 90, and subsequently at 12-week intervals.
Seizure outcome
Analysis of postoperative seizure outcome will be assessed referring to the ILAE classification system in the course of epilepsy surgical procedures: seizure freedom (ILAE class 1) will be de-fined as a favorable seizure outcome; ILAE classes 2-6 (i.e. pure auras, rare to no improvement and worsening of seizure frequency) will be referred to as unfavorable seizure outcome.
Measured: Seizure outcome will be assessed at the 12 weeks, the 6 months and all 12 week follow-up examination.
Modified Rankin Scale assessment (mRS)
The mRS will be used for measuring the degree of disability or dependence in the daily activities of patients. The mRS ranking runs from 0 to 6, where 0 is "perfect" health and 6 is death. Furthermore, 6 months after randomization of the 57th patient there will be carried out an interim safety analysis, which will evaluate differences in clinical performance (mRS) between the experimental and conventional intervention groups.
Measured: The mRS will be assessed at baseline, on postoperative day 1, and at follow-up visits on days 3, 14, 30, and 90, and subsequently at 12-week intervals.
Quality-of-life (QoL)
The EORTC quality of life (QoL) questionnaire modules QLQ-C30 and BN20 will be used to assess patients' QoL. These internationally recognized and well-validated instruments cover 26 QoL domains. Based on previous studies, particular emphasis will be placed on domains especially relevant to brain tumor patients, including global health status, physical functioning, social functioning, cognitive functioning, communication deficits, and motor dysfunction.
The questionnaires are designed for completion within approximately 10 minutes, both in the pretreatment phase and during ongoing treatment. Their validity has been demonstrated across various cancer populations and disease stages, including different treatment contexts. Test-retest reliability assessed over a four-day interval has shown good to excellent consistency across all functional domains, with Pearson's r values ranging from 0.72 to 0.91.
Measured: QoL will be assessed at baseline, at follow-up visits on days 14, 30, and 90, and subsequently at 24-week intervals.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The ATLAS/NOA-29 trial is a prospective, multicenter, phase III randomized controlled study evaluating whether anterior temporal lobectomy (ATL), a standardized resection technique adapted from epilepsy surgery, improves clinical outcomes in patients with newly diagnosed glioblastoma of the anterior temporal lobe compared to conventional gross-total resection (GTR).

Primary outcome
Overall survival
Time frame: From randomization until death or 36 months after recruitment of the last patient
OS in the modified intention to treat (mITT) population of patients with glioblastoma, Central Nervous System (CNS) World Health Organization (WHO) grade 4, Isocitrate Dehydrogenase wild-type (IDHwt)
Patient-reported Quality of Life
Time frame: From randomization until death or 36 months after recruitment of the last patient
In case of significant OS differences, the patient-reported QoL domain "global health status" (EORTC QLQ-C30 questionnaire) in the modified intention to treat (mITT) population is the co-primary endpoint. Over-all superiority of ATL requires significantly prolonged OS and non-inferiority regarding the development of the global health status over time in the mITT population.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Anterior temporal lobectomy (ATL) and Gross Total Resection (GTR) in people with Newly-diagnosed Glioblastoma and Temporal Lobe, run by University Hospital, Bonn at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 13 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall survival (time frame: From randomization until death or 36 months after recruitment of the last patient). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07021339, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jun 2025.
