Complete adverse effect profile including incidence rates and management
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 discussed in greater detail in other sections of the labeling: Hepatotoxicity [see Warnings and Precautions (5.1) ] Interstitial Lung Disease (ILD)/Pneumonitis [see Warnings and Precautions (5.2) ] Single agent in NSCLC: The most common adverse reactions (≥ 20%) were diarrhea, musculoskeletal pain, nausea, fatigue, hepatotoxicity, and cough.
The most common laboratory abnormalities (≥ 25%) were decreased lymphocytes, decreased hemoglobin, increased aspartate aminotransferase, increased alanine aminotransferase, decreased calcium, increased alkaline phosphatase, increased urine protein, and decreased sodium.
( 6.1 ) In combination with panitumumab in CRC: The most common adverse reactions (≥ 20%) in clinical trials of LUMAKRAS in combination with panitumumab are rash, dry skin, diarrhea, stomatitis, fatigue and musculoskeletal pain.
The most common Grade 3 or 4 laboratory abnormalities in ≥ 2 patients (4.3%) were decreased magnesium, decreased potassium, decreased corrected calcium, and increased potassium.

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 reflect exposure to LUMAKRAS as a single agent at 960 mg orally once daily until disease progression or unacceptable toxicity in 549 patients with NSCLC with KRAS G12C mutation in the following trials: CodeBreaK 200 (NCT04303780), CodeBreaK 100 (NCT03600883), CodeBreaK 101 (NCT04185883) and CodeBreaK 105 (NCT04380753).
Among these 549 patients who received LUMAKRAS, 44% were exposed for 6 months or longer and 21% were exposed for greater than one year.
The pooled safety population described in WARNINGS AND PRECAUTIONS also reflects exposure to LUMAKRAS 960 mg once daily in combination with panitumumab in 126 patients who received LUMAKRAS in combination with panitumumab for mCRC in CodeBreaK 300 (NCT05198934) and CodeBreaK 101 (NCT04185883).
5 WARNINGS AND PRECAUTIONS Hepatotoxicity: Monitor liver function tests every 3 weeks for the first 3 months of treatment then once monthly as clinically indicated.
Consider administering systemic corticosteroids and withhold, reduce the dose, or permanently discontinue LUMAKRAS based on the severity.
( 2.3 , 5.1 ) Interstitial Lung Disease (ILD)/Pneumonitis: Monitor for new or worsening pulmonary symptoms.
Immediately withhold LUMAKRAS for suspected ILD/pneumonitis and permanently discontinue if no other potential causes of ILD/pneumonitis are identified.
( 2.3 , 5.2 ) 5.1 Hepatotoxicity LUMAKRAS can cause hepatotoxicity and increased alanine aminotransferase (ALT) or increased aspartate aminotransferase (AST) which may lead to drug-induced liver injury and hepatitis.
Like all medications, Lumakras 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.
