This multi-site Phase II study will enroll adults with histologically confirmed diagnosis of World Health Organization (WHO) Grade IV glioblastoma (GBM), isocitrate dehydrogenase (IDH)-wildtype consistent with WHO central nervous system (CNS) 2021 criteria who have received prior first-line treatment including with at least radiotherapy and temozolomide, with a Karnofsky performance status (KPS) ≥60, adequate organ function, and at least one measurable lesion according to the response assessment in neuro-oncology (RANO) 2.0 criteria.
Adults, aged 18-75 years inclusive at the time of giving informed consent. Local laws will be followed if the age at consent is older.
Have a histologically confirmed diagnosis of WHO Grade IV GBM, IDH-wildtype consistent with WHO CNS 2021 criteria.
Have recurrent supratentorial GBM who have received prior treatment with at least radiotherapy and temozolomide.
Have first recurrence documented by magnetic resonance imaging (MRI), with an interval of at least 12 weeks after the end of prior radiotherapy unless there is either: i) histopathologic confirmation of recurrent tumor, or ii) new enhancement on MRI outside of the radiotherapy treatment field.
Any anticancer therapies, including systemic, palliative, biologic, immunostimulatory, or immunosuppressive treatment within 4 weeks (or five half-lives, whichever is longer) before starting the study treatment.
PD(L)-1/VEGF bispecific antibodies, cluster of differentiation (CD)137 agonists or other immune checkpoint blockade therapies including monotherapy with either category or combinations thereof.
