| Primary | Number of participants with dose limiting toxicities of [177Lu]Lu-EVS459 | From start of study treatment until 6 weeks after | A dose limiting toxicity (DLT) is defined as any adverse event or abnormal laboratory value of CTCAE (version 5.0) Grade 3 or higher that occurs within the DLT evaluation period and that is not primarily related to disease, disease progression, intercurrent illness, or concomitant medications with a few exceptions defined in the study protocol.
