Mobocertinib, sold under the brand name Exkivity, is a medication used to treat non-small cell lung cancer. Specifically it is used for advanced cases with an epidermal growth factor receptor (EGFR) exon 20 insertion mutation. It is taken by mouth once per day.
Common side effects include diarrhea, rash, nausea, inflammation of the mouth, vomiting, decreased appetite, finger nail infections, tiredness, dry skin, and musculoskeletal pain. Other side effects may include kidney problems, low potassium, pancreatitis, pneumonitis, and heart problems such as QTc prolongation. Use in pregnancy may harm the baby. It is a tyrosine kinase inhibitor that preferentially inhibits epidermal growth factor receptor (EGFR) bearing mutations in the exon 20 region.
Mobocertinib was approved for medical use in the United States in 2021. While it is available in the United Kingdom, it is not approved in Europe. In the United Kingdom a month of medication costs the NHS about £7800 as of 2022. In the United States this amount costs 24,600 USD.
Mobocertinib is indicated for adults with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.
It is typically used at a dose of 160 mg once per day.
More serious side effects of Mobocertinib may include agitation, bloating of the eyes, lips, feet, blurred vision, coma, decreased urine output, headache, hostility, diarrhea, depression, dizziness, fainting, lethargy, anxiety, nausea, seizures, weight gain, fatigue as well as edema.  Other side effects which may be less frequent are: chills, cough, dilated neck veins, ill-feeling and trouble with breathing.  Other notable side effects of taking Mobocertinib are: having an acidic stomach, heartburn, acidity, hair loss/thinning, bone pain, sore throat, stuffy nose, trouble swallowing, vomiting and weakness in hands and feet. 
Mobocertinib may increase the chance of QTC prolongation, specifically Torsades de Pointes which can be fatal. 
Mechanism of action
Mobocertinib acts to inhibit EGFR exon 20 insertion mutations at a lower concentration than it does on wild-type proteins.  Mobocertinib is an irreversible kinase inhibitor, forming a covalent bond with the cysteine 797 in the EGFR active site, leading to sustained inhibition of EGFR enzymatic activity. The irreversible binding leads to increased potency via higher affinity binding, more sustained EGFR kinase activity inhibition, and greater overall selectivity, as only a limited number of other kinases possess a cysteine in the equivalent position.
The volume of distribution of Mobocertinib at steady state is 3,509 L.  The mean oral bioavailability of Mobocertinib is 37%.  The median Tmax is 4 hours.  The average half-life of Mobocertinib and its metabolites is 18 hours.  Mobocertinib is metabolized by CYP3A enzymes. 
Mobocertinib was studied in participants with previously treated metastatic non-small cell lung cancer with EGFR exon 20 insertions. It is a first-in-class oral treatment to target EGFR Exon20 insertion mutations.
