The prescribing information for tarlatamab includes a boxed warning for serious or life-threatening cytokine release syndrome (CRS) and neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS).[1]
The most common adverse reactions include cytokine release syndrome, fatigue, pyrexia, dysgeusia, decreased appetite, musculoskeletal pain, and constipation, anemia and nausea.[2] The most common grade 3 or 4 laboratory abnormalities include decreased lymphocytes, decreased sodium, increased uric acid, decreased total neutrophils, decreased hemoglobin, increased activated partial thromboplastin time, and decreased potassium.[2]
History
Efficacy was evaluated in 99 participants with relapsed/refractory extensive stage small cell lung cancer with disease progression following platinum-based chemotherapy enrolled in DeLLphi-301 [NCT05060016], an open-label, multicenter, multi-cohort study.[2] Participants with symptomatic brain metastases, interstitial lung disease or non-infectious pneumonitis, and active immunodeficiency were excluded.[2] Participants received tarlatamab until disease progression or unacceptable toxicity.[2]
