ListOutcomeTime frameDescription
PrimaryIntracranial overall response rate (ORR)Up to 36 months
Brain metastases ORR is defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) based on central and local investigator's assessment according to RANO-BM criteria on brain MRI
SecondaryBrain metastases (BM) disease control rate (DCR)Up to 36 months
DCR is defined as the proportion of participants with Best Overall Response (BOR) of Complete Response (CR), Partial Response (PR), Stable Disease (SD) or Non-CR/Non-PD according to RANO-BM on brain MRI
SecondaryMedian CNS PFSUp to 36 monthsAccording to RANO-BM on brain MRI
SecondaryExtracranial ORRUp to 36 months
Extracranial ORR is evaluated according to RECIST 1.1, measured with CT. ORR is defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) based on local investigator's assessment
SecondaryExtracranial DCRUp to 36 months
Extracranial DCR is evaluated according to RECIST 1.1, measured with CT. DCR is defined as the proportion of participants with Best Overall Response (BOR) of CR, PR, Stable Disease (SD) or Non-CR/Non-PD.
SecondaryExtracranial PFSUp to 36 months
Extracranial progression free survival (PFS) will be assessed according to RECIST 1.1 based on CT. PFS is the time from date of start of treatment to the date of event defined as the first documented progression or death due to any cause.
SecondaryOverall PFSUp to 36 monthsOverall progression free survival (PFS) is evaluated according to RECIST 1.1 based on CT for extracranial lesions, and RANO-BM based on MRI for BM.
SecondaryOverall survivalUp to 48 monthsOverall survival (OS) is defined as the time from date of start of treatment to date of death due to any cause
SecondaryNumber of patients experiencing adverse events according to CTCAE and ASTCT criteriaUp to 36 months
Number of patients experiencing adverse events, according to ASTCT 2019 criteria for immuno effector cell-associated neurotoxicity syndrome (ICANS) and cytokine release syndrome (CRS), and according to CTCAE v5.0 for other adverse events.
OtherEfficacy of tarlatamab (survival) in relation to previous cranial radiotherapyUp to 36 months
Exploratory endpoint: comparison of the efficacy of tarlatamab in patients who previously received cranial radiotherapy to the efficacy in those who were not previously treated with cranial radiotherapy
OtherSafety of tarlatamab (adverse events) in relation to previous cranial radiotherapyUp to 36 months
Exploratory endpoint: comparison of the safety of tarlatamab in patients who previously received cranial radiotherapy to the safety of tarlatamab in those who were not previously treated with cranial radiotherapy
OtherEfficacy of tarlatamab in relation to concomitant steroid useUp to 36 monthsExploratory endpoint: comparison of the efficacy of tarlatamab in patients who concomitantly used steroids to the efficacy in those who were not concomitant steroid users.
OtherSafety of tarlatamab (i.e. adverse events) in relation to concomitant steroid useUp to 36 monthsExploratory endpoint: comparison of the safety of tarlatamab in patients who concomitantly used steroids to the safety in those who were not concomitant steroid users.
OtherEvaluate immune environment in cerebrospinal fluid (with lumbar puncture) versus peripheral blood in relation to SCLC responsesUp to 36 months
Exploratory endpoint: tumor response (BM and extracranial response, such as progressive disease, stable disease or (partial) response) in relation to baseline and 12 week evaluation of immune cells in liquor and peripheral blood, respectively. Lumbar puncture not mandatory
