What side effects has Exkivity (mobocertinib) been associated with?
Exkivity (mobocertinib) is a cancer medicine used for specific patients with EGFR exon 20 insertion–mutated non-small cell lung cancer. Reported side effects include gastrointestinal effects, skin/nail effects, fatigue, and lab abnormalities, along with heart-rhythm–related risks that require monitoring.
What are the most common side effects patients report?
Across clinical experience, the side effects most often associated with Exkivity include:
- Diarrhea
- Nausea
- Vomiting
- Decreased appetite
- Fatigue
- Rash
- Dry skin and nail-related effects
- Stomatitis (mouth sores)
What serious side effects should be watched for?
Exkivity also carries potentially serious risks. The biggest safety issue is heart rhythm changes, which is why clinicians typically monitor ECGs and electrolytes during treatment. Other serious concerns include:
- Severe or persistent diarrhea and dehydration
- Severe skin reactions
- Interstitial lung disease / pneumonitis (lung inflammation), which can be life-threatening
How do diarrhea and nausea usually affect treatment?
Diarrhea is a key concern with mobocertinib. When it is severe, it can lead to dehydration and electrolyte problems, which may require dose interruption, dose reduction, supportive medicines, and close follow-up. Nausea and vomiting can similarly affect hydration and overall tolerance of therapy.
How do clinicians manage Exkivity side effects?
Management typically includes:
- Supportive medicines for diarrhea, nausea, and skin symptoms
- Dose interruptions or dose reductions if side effects are significant
- Regular lab checks and safety monitoring, including heart rhythm monitoring (ECG) and electrolyte monitoring
Who is at higher risk for complications?
Risk can be higher in patients who already have:
- Heart rhythm problems or significant electrolyte abnormalities
- Prior lung disease or prior lung inflammation from treatment
- A history of severe gastrointestinal intolerance
