About this study

Official title: A Phase Ib Dose Finding Study Assessing Safety and Activity of [177Lu]Lu-DOTA-TATE in Newly Diagnosed Glioblastoma in Combination With Radiotherapy With or Without Temozolomide and in Recurrent Glioblastoma as Single Agent

A Dose Finding Study of [177Lu]Lu-DOTA-TATE in Newly Diagnosed Glioblastoma in Combination with Standard of Care and in Recurrent Glioblastoma as a Single Agent

Read the detailed description

The study for each participant consists of a Screening period, a Treatment period and a 12-month Follow-up period.

During the screening period of up to 6 weeks before starting GBM treatment, each participant will be assessed for somatostatin receptor (SSTR) expression by [68Ga]Ga-DOTA-TATE imaging PET/scan.

Eligible participants with newly diagnosed glioblastoma will be assigned to Group 1 :

  • Participants in Group 1 (concomitant radiotherapy + temozolomide and temozolomide maintenance) will receive treatment with [177Lu]Lu-DOTA-TATE every 4 weeks +/- 2 days, up to 6 administrations. Radiotherapy and temozolomide will be administered 7 to 10 days after the first administration of [177Lu]Lu-DOTA-TATE. Temozolomide will be administered orally at a dose of 75 mg/m2/day during the concomitant period, concurrently with radiotherapy. Radiotherapy will be delivered at a dose of 2 Gray (Gy)/day, 5 days per week followed by 2 days of rest, for 6 consecutive weeks with a total dose of 60 Gy (without interruption). During the maintenance period, there is an intra-patient dose escalation in temozolomide treatment. The dosage of temozolomide is 150 mg/m2 in Cycle 1 of maintenance period, and then to 200 mg/m2 in Cycle 2 and beyond in the maintenance period, if 150 mg/m2 temozolomide treatment is well tolerated in Cycle 1.

Eligible participants with recurrent glioblastoma will be assigned to Group 3 and will receive [177Lu]Lu-DOTA-TATE as single agent treatment every 3 weeks +/- 2 days.

An infusion of sterile 2.5% Lysine - Arginine amino acid (AA) solution will be co-administered with each [177Lu]Lu-DOTA-TATE dose for renal protection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Group 1: Frequency of dose limiting toxicities (DLTs)

    A dose-limiting toxicity (DLT) is defined as an AE or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications that meets any of the criteria defining dose-limiting toxicities and with an onset during the DLT observation period specified for the group.

    • Group 1: DLT observation period of 49 to 52 days starting from the first administration of [177Lu]Lu-DOTA-TATE (Day 1) and ending with the completion of concomitant RT and TMZ. The 49 to 52 days observation period is depending on the start day of concomitant RT and TMZ (i.e. 7-10 days post first [177Lu]Lu-DOTA-TATE dose). If the concomitant RT and TMZ is delayed for any reason, the DLT observation period will last until the completion of the concomitant treatment. If RT or TMZ is delayed, the DLT observation period will last until the last administered dose, whichever occurs later.

    Measured: 49 to 52 days starting from first administration of [177Lu]Lu-DOTA-TATE

  2. Group 3: Frequency of dose limiting toxicities (DLTs)

    A dose-limiting toxicity (DLT) is defined as an AE or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications that meets any of the criteria defining dose-limiting toxicities and with an onset during the DLT observation period specified for the group.

    • Group 3: DLT observation period of 42 days starting from the first administration of [177Lu]Lu-DOTA-TATE (Day 1) i.e. accounting for 2 cycles of Lu]Lu-DOTA-TATE.

    Measured: 42 days starting from first administration of [177Lu]Lu-DOTA-TATE

Secondary outcomes (28)
  1. Incidence and severity of adverse events (AEs), serious AEs (SAEs) of [177Lu]Lu-DOTA-TATE

    The distribution of adverse events of [177Lu]Lu-DOTA-TATE will be done via the analysis of frequencies for treatment emergent Adverse Event (TEAEs), Serious Adverse Event (TESAEs) and Deaths due to AEs, through the monitoring of relevant clinical and laboratory safety parameters.

    During the follow up period, all AEs and lab abnormalities will be collected within 8 weeks after the last dose of study treatment. For participants with study drug related AEs, they will be followed until resolution or until the End of Study, whichever occurs first. Apart from that, only survival information, SAEs, that are considered related to study drug by the Investigator, and AEs of secondary hematological malignancies will be collected until the end of follow up period every 8 weeks.

    Measured: Up to approximately 2 years (estimated final OS analysis) from date of first study treatment

  2. Incidence and severity of Adverse Events (AEs) and serious Adverse Events (SAEs) within 48 hours after [68Ga]Ga-DOTA-TATE infusion

    The distribution of adverse events of [68Ga]Ga-DOTA-TATE will be done via the analysis of frequencies for treatment emergent Adverse Event (TEAEs), Serious Adverse Event (TESAEs) and Deaths due to AEs, through the monitoring of relevant clinical and laboratory safety parameters.

    Measured: up to 48 hours following the start of [68Ga]Ga-DOTA-TATE administration

  3. Overall Objective Status as per modified Response Assessment in Neuro-Oncology (mRANO) criteria

    According to modified RANO, the objective overall status combines the radiographic response on target lesions, new disease, neurological status and use of steroids and the result is reported as confirmed or preliminary CR, confirmed or preliminary PR, stable disease, confirmed or preliminary disease progression. The best objective overall status achieved during the study will be summarized using frequency and percentage. The rate of confirmed complete or partial response will be summarized using point estimate and 2-sided exact binomial 95% confidence interval (Clopper-Pearson) and presented by dose level within each group.

    Measured: Up to approximately 2 years (estimated final OS analysis) from date of first study treatment

  4. Progression-Free Survival (PFS)

    Progression-Free Survival (PFS) is defined as the time from the date of first dose to the date of confirmed progression according to modified RANO or death due to any cause. If no PFS event is observed, PFS will be censored at the date of the last adequate tumor assessment prior to data cut-off date and start of new anti neoplastic therapy, whichever comes first. PFS will be analyzed in the FAS population and results will be presented for each dose level within each group. The PFS distribution will be estimated using the Kaplan-Meier method.

    Measured: From date of randomization until date of progression or date of death from any cause, whichever come first, assessed for up to 2 years (estimated final OS analysis)

  5. Overall Survival (OS)

    Overall Survival (OS) is defined as the time from date of first dose to date of death due to any cause. If a participant is not known to have died, then OS will be censored at the latest date the participant was known to be alive (on or before the cut-off date). OS will be analyzed in the FAS population and results will be presented for each dose level within each group. The OS distribution will be estimated using the Kaplan-Meier method.

    Measured: Up to approximately 2 years (estimated final OS analysis) from date of first study treatment

    Measured: Week 4 Day 1 (pre-dose, before the end of infusion, 2 hours post-dose, 6 hours post-dose), Week 4 Day 2 (24 hours post-dose), Week 4 Day 3 (48 hours post-dose), Week 4 Day 8 (168 hours post-dose)

  27. Group 3: Terminal-Phase Disposition Rate Constant (λz) of [177Lu]Lu-DOTA-TATE

    Venous whole blood samples will be collected and analysed for radioactivity. Radioactivity based concentration units will be converted to mass-based concentration units using the specific activity of the dose at the time of manufacture (MBq/µg). Pharmacokinetics characterization will be performed on mass-based concentrations. Terminal-Phase Disposition Rate Constant will be listed and summarized using descriptive statistics.

    Measured: Week 4 Day 1 (pre-dose, before the end of infusion, 2 hours post-dose, 6 hours post-dose), Week 4 Day 2 (24 hours post-dose), Week 4 Day 3 (48 hours post-dose), Week 4 Day 8 (168 hours post-dose)

  28. Quantification of [177Lu]Lu-DOTA-TATE excreted from the body in urine

    All excreted urine from the start of [177Lu]Lu-DOTA-TATE infusion until the first whole body planar imaging will be collected, its volume measured and the radioactivity concentration kilobecquerel per milliliter (kBq/mL) determined in order to calculate the total radioactivity excreted from the body from the start of [177Lu]Lu-DOTA-TATE infusion to the time of the first scan. If no urine is excreted from the start of [177Lu]Lu-DOTA-TATE infusion until the first whole body planar imaging, no urine dosimetry is necessary.

    Measured: From the start of [177Lu]Lu-DOTA-TATE infusion until the first whole body planar imaging

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [177Lu]Lu-DOTA-TATE, [68Ga]Ga-DOTA-TATE and Temozolomide in people with Glioblastoma, run by Novartis Pharmaceuticals at 14 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 14 exclusion criteria. 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: under way, not looking for participants, as of the sponsor's last update on 22 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in Spain, United States, France, Switzerland, Portugal. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Group 1: Frequency of dose limiting toxicities (DLTs) (time frame: 49 to 52 days starting from first administration of [177Lu]Lu-DOTA-TATE). 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?
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 22 Sep 2026.
