• Group 1: Frequency of dose limiting toxicities (DLTs) [ Time Frame: 49 to 52 days starting from first administration of [177Lu]Lu-DOTA-TATE ]
  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.

  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.

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.
