Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Part I: Dose Escalation
Participants with newly diagnosed GBM will receive RO7428731, intravenously (IV), up to one year or until disease progression, withdrawal of consent, unacceptable toxicity, or death, whichever occurs first.
 Drug: RO7428731
Participants will receive RO7428731 as described.
Experimental: Part II: Dose-Expansion(s)
Participants with newly diagnosed GBM will receive RO7428731, IV, in maximum of two dose expansion cohorts at a dose(s) not exceeding the maximum tolerated dose (MTD) established in Part I.
 Drug: RO7428731
Participants will receive RO7428731 as described.
Experimental: Part III: Safety Run-in
Participants with recurrent GBM will receive RO7428731, IV in a dosing schedule determined in Part I. At the end of the Safety Run-in period, a decision will be made as to whether to open the Dose-Expansion Cohort Part IVA or open a second Safety Run-in Cohort at a lower dose.
 Drug: RO7428731
Participants will receive RO7428731 as described.
Experimental: Part IV A: Dose-Expansions Cohort
Participants with recurrent GBM will receive RO7428731, IV at specified doses and dosing schedules.
 Drug: RO7428731
Participants will receive RO7428731 as described.


Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants with Adverse Events (AEs) [ Time Frame: Up to the safety follow-up visit 60 days after the last treatment (up to approximately 15 months) ]
  2. Percentage of Participants with Dose Limiting Toxicities (DLTs) [ Time Frame: Cycle 1 (each cycle is 21 days) ]

Secondary Outcome Measures :
  1. Serum Concentration of RO7428731 [ Time Frame: Up to the safety follow-up visit 60 days after the last treatment (up to approximately 15 months) ]
  2. Percentage of Participants With RO7428731 Anti-drug Antibodies (ADAs) [ Time Frame: From baseline up to the safety follow-up visit 60 days after the last treatment (up to approximately 15 months) ]
  3. Objective Response Rate (ORR) [ Time Frame: From start of study treatment up to approximately 3 years ]
  4. Disease Control Rate (DCR) [ Time Frame: From start of study treatment up to approximately 3 years ]
  5. Duration of Response (DOR) [ Time Frame: From the time of first occurrence of a documented response until the time of documented disease progression or death (death within 30 days from last study treatment) from any cause, whichever occurs first (up to approximately 3 years) ]
  6. Progression-free Survival (PFS) [ Time Frame: From start of study treatment to the first occurrence of documented disease progression or death from any cause, whichever occurs first (up to approximately 3 years) ]
  7. Overall Survival (OS) [ Time Frame: From start of study treatment to the time of death from any cause (up to approximately 3 years) ]

Criteria

Inclusion Criteria:

Inclusion criteria for all participants:

  • Participants (in Part I): Adult participants with newly diagnosed EGFRvIII-positive GBM with unmethylated MGMT promotor status who have completed standard of care therapy with surgical resection and adjuvant radiotherapy with or without concomitant temozolomide. Participants are allowed to have received any number of cycles of temozolomide maintenance. Adult participants with newly diagnosed EGFRvIII-positive GBM with methylated MGMT promotor status who have completed standard of care with surgical resection and adjuvant radiotherapy with concomitant and maintenance temozolomide or discontinued temozolomide maintenance due to reasons other than progressive disease.
  • Participants (in Part II): Adult participants with newly diagnosed EGFRvIII-positive GBM with unmethylated MGMT promotor status who have completed standard of care therapy with surgical resection and adjuvant radiotherapy with or without concomitant temozolomide.

Inclusion criteria for Part III and Part IV A only:

  • Documented first or second recurrence of GBM
  • At least one measurable GBM lesion as per Response Assessment in Neuro-Oncology (RANO) criteria prior to initiation of study treatment.

Exclusion Criteria:

Exclusion criteria for all participants:

  • Presence of extracranial metastatic or leptomeningeal disease
  • Known hypersensitivity to immunoglobulins or to any other component of the investigational medicinal product formulation
  • Active bleeding or pathological condition that carries a high risk of bleeding, including inherited and acquired coagulopathies
  • Participants unable to undergo an MRI with contrast.

Exclusion criteria for Part I and Part II only:

  • Recurrent malignant gliomas
  • Any prior anti-tumor treatment for GBM: tumor resection, adjuvant radiotherapy with or without concomitant temozolomide and temozolomide maintenance (Part I only) must be the only tumor-directed treatment that the participant has received for GBM.
