What this study is testing
What is Tarlatamab?
Tarlatamab is an investigational medicine, being studied as a potential treatment for astrocytic tumor.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This is a phase 2 study to assess how useful study drug tarlatamab is for the treatment of patients with recurrent/refractory oligodendroglioma or astrocytoma with a mutation in the IDH gene.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.

- Patients could have received up to 2 regimens of systemic therapy after relapse.
- For Cohort 1: Patient must be clinically deemed resectable and a resection is clinically indicated.

- Patients must be asymptomatic and meet the following criteria:
- At least 28 days after the most recent CNS treatment, clinically stable.
- At least 14 days on stable doses of corticosteroids and/or anti-seizure medications.

- Any previous treatment with tarlatamab.
- Other malignancy within the last 5 years with exceptions.
- Patients receiving any systemic chemotherapy or radiotherapy within 28 days prior to study treatment.
- Unresolved toxicity from prior anti-tumor therapy or prior surgery.
- Major surgery within 28 days of starting study treatment and patients must have recovered from any effects of any major surgery.
- Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection.
- History of arterial thrombosis within 12 months of first dose of tarlatamab.
- Patients who are pregnant, lactating, or intend to become pregnant during their participation in this study.
- Patients with symptoms and/or clinical signs and/or radiographic signs that indicate an acute and/or uncontrolled active systemic infection within 7 days prior to the first dose of tarlatamab.

- Exclusion of hepatitis infection based on the following results and/or criteria (within 3 months prior to the first dose of tarlatamab):
- Positive for hepatitis B surface antigen (HBsAg) (indicative of chronic hepatitis B or recent acute hepatitis B).
- Negative HBsAg and positive for hepatitis B core antibody: hepatitis B virus DNA by polymerase chain reaction (PCR) is necessary. Detectable hepatitis B virus DNA suggests occult hepatitis B.
