Important Safety Information
This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Cytokine Release Syndrome (CRS) [see Warnings and Precautions (5.1) ] Neurologic Toxicity Including ICANS [see Warnings and Precautions (5.2) ] Cytopenias [see Warnings and Precautions (5.3) ] Infections [see Warnings and Precautions (5.4) ] Hepatotoxicity [see Warnings and Precautions (5.5) ] Hypersensitivity [see Warnings and Precautions (5.6) ] The most common adverse reactions (> 20%) were cytokine release syndrome, fatigue, decreased appetite, anemia, dysgeusia, pyrexia, constipation, musculoskeletal pain, and nausea.
The most common (≥ 5%) Grade 3 or 4 laboratory abnormalities were decreased lymphocytes, decreased sodium, decreased total neutrophils, and increased uric acid.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The pooled safety population described in the WARNINGS AND PRECAUTIONS reflects exposure to intravenous IMDELLTRA, as a single agent, at the recommended dosage of IMDELLTRA 1 mg on Cycle 1 Day 1 followed by 10 mg on Days 8 and 15, and then every 2 weeks until disease progression or intolerable toxicity in 473 patients with small cell lung cancer enrolled in three clinical trials: DeLLphi-300, DeLLphi-301 and DeLLphi-
Among 473 patients who received IMDELLTRA, 40% were exposed for 6 months or longer and 19% were exposed for greater than one year.
The most common (≥ 20%) adverse reactions were CRS (57%), fatigue (48%), decreased appetite (38%), dysgeusia (34%), pyrexia (33%), constipation (31%), musculoskeletal pain (31%), and nausea (25%).
The most common (≥ 5%) Grade 3 or 4 laboratory abnormalities were decreased lymphocytes (43%), decreased sodium (12%), decreased total neutrophils (9%), and increased uric acid (6%).
Extensive Stage Small Cell Lung Cancer The safety of IMDELLTRA was evaluated in 252 patients in DeLLphi-304, a multicenter, randomized, open label trial in patients with extensive stage small cell lung cancer (ES- SCLC) with disease progression following treatment with platinum-based chemotherapy with or without an anti-PD-(L)1 antibody [see Clinical Studies (14.1) ].
5 WARNINGS AND PRECAUTIONS Cytopenias : Monitor complete blood counts prior to administration of all doses of IMDELLTRA up through Cycle 5 Day 15 and then prior to administration of IMDELLTRA on Day 1 of each cycle starting with Cycle
More frequent evaluation may be necessary as clinically indicated.
Withhold or permanently discontinue based on severity.
( 5.3 ) Infections : Monitor for signs and symptoms of infection;
treat appropriately.
Like all medications, Imdelltra (amg757) can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
