What are the uses of this medicine?[edit | edit source]

Adagrasib (Krazati) is a prescription medicine used to treat adults with non-small cell lung cancer (NSCLC):

that has spread to other parts of the body or cannot be removed by surgery, and
whose tumor has an abnormal KRAS G12C gene, and
who have received at least one prior treatment for their cancer.

How does this medicine work?[edit | edit source]

Adagrasib is an irreversible inhibitor of KRAS G12C that covalently binds to the mutant cysteine in KRAS G12C and locks the mutant KRAS protein in its inactive state that prevents downstream signaling without affecting wild-type KRAS protein.
Adagrasib inhibits tumor cell growth and viability in cells harboring KRAS G12C mutations and results in tumor regression in KRAS G12C-mutated tumor xenograft models with minimal off-target activity.

What special precautions should I follow?[edit | edit source]

Krazati can cause severe gastrointestinal adverse reactions. Advise patients that Krazati can cause severe gastrointestinal adverse reactions and to contact their healthcare provider for signs or symptoms of severe or persistent gastrointestinal adverse reactions.
Krazati can cause QTc interval prolongation, which can increase the risk for ventricular tachyarrhythmias (e.g., torsades de pointes) or sudden death. Avoid concomitant use of Krazati with other products with a known potential to prolong the QTc interval. Monitor ECG and electrolytes in patients at risk, and in patients taking medications known to prolong the QT interval. Withhold, reduce the dose, or permanently discontinue based on severity.
Krazati can cause hepatotoxicity, which may lead to drug-induced liver injury and hepatitis. Monitor liver laboratory tests prior to the start of Krazati and monthly for 3 months after and as clinically indicated. Reduce the dose, withhold, or permanently discontinue based on severity.
Krazati can cause interstitial lung disease (ILD)/pneumonitis, which can be fatal. Monitor for new or worsening respiratory symptoms. Withhold Krazati for suspected ILD/pneumonitis and permanently discontinue if no other potential causes of ILD/pneumonitis are identified.
