Warnings
Black Box Warnings
QTc prolongation and torsades de pointes
- Life-threatening heart rate–corrected QTc prolongation, including torsades de pointes, may occur
- Monitor QTc and electrolytes periodically during treatment
- Increase monitoring frequency in patients with risk factors for QTc prolongation (eg, congenital long QT syndrome, heart disease, electrolyte abnormalities)
- Avoid coadministration with drugs that may further prolong the QTc interval (eg, drugs known to prolong QTc interval, strong or moderate CYP3A inhibitors)
- Withhold, reduce dose, or permanently discontinue treatment based on the severity of QTc prolongation
Contraindications
None
Cautions
ILD/pneumonitis, which can be fatal, reported; monitor for new or worsening pulmonary symptoms indicative of ILD/pneumonitis
Cardiac toxicity (including decreased EF, cardiomyopathy, and congestive HF) resulting in HF, may occur; monitor cardiac function (eg, assessment of left ventricular EF at baseline and during treatment)
May cause fetal harm
QTc prolongation and torsades de pointes
- Life-threatening QTc prolongation, including torsades de pointes, reported
- Assess QTc and electrolytes at baseline and correct abnormalities in sodium, potassium, calcium, and magnesium before initiating therapy
Diarrhea
- Severe diarrhea reported
- Median time to first onset of diarrhea was 5 days; diarrhea occurred within 24 hr after administration
- Diarrhea may lead to dehydration or electrolyte imbalance, with or without renal impairment; treat diarrhea promptly
- Advise patients to start an antidiarrheal agent (eg, loperamide) at first sign of diarrhea or increased bowel movement frequency and to increase fluid and electrolyte intake
- Monitor electrolytes
Drug interaction overview
- CYP3A4 substrate
- Moderate CYP3A4 inducer
- Inhibitor of breast cancer resistance protein (BCRP); clinical significance of changes in pharmacokinetics of sulfasalazine (a BCRP substrate) when coadministered with multiple doses of mobocertinib is unknown
-
Strong or moderate CYP3A4 inhibitors
- Avoid coadministration
- If use of moderate CYP3A4 inhibitors is unavoidable, reduce mobocertinib dose and monitor QTc interval more frequently
- Strong or moderate CYP3A4 inhibitors may increase mobocertinib plasma concentrations and toxicities, including QTc interval
-
Strong or moderate CYP3A4 inducers
- Avoid coadministration
- Strong or moderate CYP3A4 inducers may decrease mobocertinib plasma concentrations and antitumor activity
-
Sensitive CYP3A4 substrates
- Avoid coadministration with hormonal contraceptives OR other CYP3A4 substrates where minimal concentration changes may lead to serious therapeutic failures
- If use is unavoidable, increase CYP3A4 substrate dosage in accordance with its prescribing information
- Mobocertinib may decrease plasma concentrations of CYP3A4 substrates
-
Drugs that prolong QTc interval
- Avoid coadministration
- If coadministration unavoidable, reduce mobocertinib dose and monitor QTc interval more frequently
Pregnancy & Lactation
Pregnancy
Based on findings from animal studies and its mechanism of action, may cause fetal harm when administered to pregnant females
No data are available on use in pregnant females
Verify pregnancy status in females of reproductive potential
Contraception
- Females of reproductive potential: Use effective nonhormonal contraception during treatment and for 1 month after last dose; mobocertinib may render hormonal contraceptives ineffective
- Males with female partners of reproductive potential: Use effective contraception during treatment and for 1 week after the last dose
Infertility
- Based on animal studies, fertility in males and females of reproductive potential may be impaired
Animal data
- Oral administration to pregnant rats during organogenesis resulted in embryolethality and maternal toxicity at plasma exposures approximately 1.7x the human exposure based on AUC at the 160-mg once-daily clinical dose
- Advise pregnant females of potential risk to a fetus
Lactation
There are no data on presence of mobocertinib or its metabolites in human milk, its effects on breastfed children, or its effects on milk production
Advise women not to breastfeed during treatment and for 1 week after last dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Kinase inhibitor of EGFR; irreversibly binds to and inhibits EGFR exon 20 insertion mutations at lower concentrations than wild-type (WT) EGFR
In cultured cell models, mobocertinib inhibited cell proliferation driven by different EGFR exon 20 insertion mutation variants
In animal tumor implantation models, mobocertinib exhibited antitumor activity against xenografts with the EGFR exon 20 insertions NPH or ASV
Absorption
Peak plasma time: 4 hr
Absolute bioavailability: 37%
Distribution
Plasma bound: 99.3%
Vd (steady-state): 3509 L
Plasma-to-blood ratio
- Mobocertinib: 0.76
- AP32960: 1.2
- AP32914: 0.71
Metabolism
Primarily metabolized by CYP3A4
Active metabolites: AP32960 and AP32914 are equipotent to mobocertinib and account for 36% and 4% of the combined molar AUC, respectively
Elimination
Half-life (steady-state)
- Mobocertinib: 18 hr
- AP32960: 24 hr
- AP32914: 18 hr
Clearance (steady-state)
- Mobocertinib: 138 L/hr
- AP32960: 149 L/hr
- AP32914: 159 L/hr
Excretion
- Mobocertinib: Feces (76% [6% unchanged]); urine (4% [1% unchanged])
- AP32960: Feces (12%); urine (1%)
- AP32914: Below detection limit in both urine and feces
Administration
Oral Administration
Take with or without food at same time each day
Swallow capsules whole; do not open, chew, or dissolve contents
Missed or vomited dose
- Missed dose >6 hr: Skip dose and take next dose the following day at its regularly scheduled time
- Vomited dose: Do not take an additional dose; take next dose as prescribed the following day
Storage
Store at 20-25ºC (68-77ºF); excursions permitted to 15-30ºC (59-86ºF)
