Pregnancy & Lactation
Pregnancy
No data are available on use in pregnant females
Animal data
- In a rabbit embryofetal development study, oral administration of sotorasib during organogenesis resulted in lower fetal body weights and a reduction in the number of ossified metacarpals in fetuses at the 100-mg/kg dose level (~2.6x the human exposure based on AUC at the clinical dose of 960 mg), which was associated with maternal toxicity, including decreased body weight gain and food consumption during dosing phase
Lactation
There are no data on drug presence or its metabolites in human milk, effects on the breastfed children, or effects on milk production
Advise women not to breastfeed during treatment and for 1 week after final 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
KRASG21C inhibitor
Forms an irreversible, covalent bond with the unique cysteine of KRASG12C, locking the protein in an inactive state that prevents downstream signaling without affecting wild-type KRAS
Also, blocks KRAS signaling, inhibits cell growth, and promotes apoptosis only in KRASG12C tumor cell lines
Absorption
Steady-state reached at 22 days
Peak plasma time: 1 hr
Effect of food
- 960-mg dose administered with a high-fat, high-calorie meal (containing ~800-1000 calories with 150, 250, and 500-600 calories from protein, carbohydrate, and fat, respectively): Sotorasib AUC increased by 25% compared with fasted conditions
Distribution
Vd (steady-state): 211 L
Protein bound: 89%
Metabolism
Main metabolic pathways of sotorasib are nonenzymatic conjugation and oxidative metabolism with CYP3A
Elimination
Half-life: 5 hr
Clearance (steady-state): 26.2 L
Excretion: Feces (74% [53% unchanged]); urine (6% [1%unchanged])
Administration
Oral Administration
Take with or without food at same time each day
Swallow tablets whole; do not chew, crush, or split tablets
Missed dose
- Missed >6 hr: Take next dose as prescribed the next day; do not double dose
- Vomited dose: Do not take an additional dose; take next dose as prescribed the next day
Difficulty swallowing solids
- Disperse tablets in 120 mL (4 ounces) of noncarbonated, room temperature water without crushing; do not use other liquids
- Stir for ~ 3 minutes until tablets are dispersed into small pieces (NOTE: tablets will not completely dissolve) and drink immediately or within 2 hr; mixture appearance may range from pale to bright yellow
- Swallow mixture; do not chew tablet pieces; rinse container with an additional 120 mL (4 ounces) of water and drink; if not consumed immediately, stir mixture again to ensure that tablets are dispersed
Storage
Store at 20-25°C (68-77°F); excursions permitted to 15-30°C (59-86°F)
