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.

  11. 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) ]
  12. 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) ]
  13. Overall Survival (OS) [ Time Frame: From start of study treatment to the time of death from any cause (up to approximately 3 years) ]
