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: Diarrhea [see Warnings and Precautions (5.1) ] Hepatotoxicity [see Warnings and Precautions (5.2) ] Interstitial Lung Disease (ILD)/Pneumonitis [see Warnings and Precautions (5.3) ] Ocular Toxicity [see Warnings and Precautions (5.4) ] Pancreatic Enzyme Elevation [see Warnings and Precautions (5.5) ] Most common adverse reactions (>20%) : diarrhea, rash, paronychia, stomatitis, and nausea.
Most common Grade 3 or 4 laboratory abnormalities (≥2%) : decreased potassium, increased lipase, decreased lymphocyte count, decreased sodium, increased amylase, increased ALT, and increased AST.

6.1 Clinical Trial 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 in the WARNINGS AND PRECAUTIONS reflects exposure to HYRNUO at 20 mg orally twice daily in 268 patients with locally advanced or metastatic NSCLC harboring HER2 and/or other mutations from the SOHO-01 study [see Clinical Studies (14) ] .
Among 268 patients who received HYRNUO, 35% were exposed for greater than 6 months and 12% were exposed for greater than 1 year.
In this pooled safety population, the most common (>20%) adverse reactions were diarrhea, rash, stomatitis, and paronychia.
The most common (≥2%) Grade 3 or 4 laboratory abnormalities were decreased potassium, increased lipase, decreased lymphocyte count, decreased sodium, increased amylase, increased ALT, and increased AST.
The safety of HYRNUO at 20 mg orally twice daily was evaluated in 136 patients with locally advanced or metastatic NSCLC harboring HER2 activating mutations who had received prior systemic therapy in the SOHO-01 study [see Clinical Studies (14) ] .
5 WARNINGS AND PRECAUTIONS Diarrhea : At the first sign of diarrhea or increased bowel movement frequency, instruct patients to start an antidiarrheal treatment, and to increase their fluid and electrolyte intake.
Interrupt, reduce the dose, or permanently discontinue HYRNUO based on severity.
( 5.1 ) Hepatotoxicity : Monitor liver function tests including ALT, AST, and total bilirubin at baseline prior to administration of HYRNUO, every 2 weeks during the first month, and then monthly thereafter as clinically indicated, with more frequent testing in patients who develop transaminase elevations.
Interrupt, reduce the dose, or permanently discontinue HYRNUO based on severity.
( 5.2 ) Interstitial Lung Disease (ILD)/Pneumonitis : Monitor patients for new or worsening symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever).
Like all medications, Hyrnuo 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.
