5 WARNINGS AND PRECAUTIONS
5.1 Gastrointestinal Adverse Reactions
KRAZATI can cause severe gastrointestinal adverse reactions.
In the pooled safety population [see Adverse Reactions (6.1)], who received single-agent KRAZATI, serious gastrointestinal adverse reactions observed were gastrointestinal bleeding in 3.8% including 0.8% Grade 3 or 4, gastrointestinal obstruction in 1.6% including 1.4% Grade 3 or 4, colitis in 0.5% including 0.3% Grade 3, ileus in 0.5%, and stenosis in 0.3%. In addition, nausea, diarrhea, or vomiting occurred in 89% of 366 patients, including 9% Grade 3. Nausea, diarrhea, or vomiting led to dosage interruption or dose reduction in 29% of patients and permanent discontinuation of adagrasib in 0.3%.
In patients who received KRAZATI in combination with cetuximab [see Adverse Reactions (6.1)], serious gastrointestinal adverse reactions included gastrointestinal bleeding in 8.5% including 1.1% Grade 3 or 4, gastrointestinal obstruction in 5.3% including 5.3% Grade 3 or 4, colitis in 1.1% including 1.1% Grade 3 and ileus in 1.1%. In addition, nausea, diarrhea, or vomiting occurred in 92% of 94 patients, including 6% Grade 3. Nausea, diarrhea, or vomiting led to adagrasib dose interruption or dose reduction in 23% of patients.
Monitor and manage patients using supportive care, including antidiarrheals, antiemetics, or fluid replacement, as indicated. Withhold, reduce the dose, or permanently discontinue KRAZATI based on severity [see Dosage and Administration (2.3)].
5.2 QTc Interval Prolongation
KRAZATI can cause QTc interval prolongation, which can increase the risk for ventricular tachyarrhythmias (e.g., torsades de pointes) or sudden death.
In the pooled safety population [see Adverse Reactions (6.1)] who received single-agent KRAZATI, 6% of 366 patients with at least one post-baseline electrocardiogram (ECG) assessment had an average QTc ≥ 501 msec and 11% of patients had an increase from baseline of QTc > 60 msec. KRAZATI causes concentration-dependent increases in the QTc interval [see Clinical Pharmacology (12.2)].
In patients who received KRAZATI in combination with cetuximab [see Adverse Reactions (6.1)], 5% of 93 patients with at least one post-baseline electrocardiogram (ECG) assessment had an average QTc ≥ 501 msec and 16% of patients had an increase from baseline of QTc > 60 msec.
Avoid concomitant use of KRAZATI with other products with a known potential to prolong the QTc interval [see Drug Interactions (7.3) and Clinical Pharmacology (12.2)]. Avoid use of KRAZATI in patients with congenital long QT syndrome and in patients with concurrent QTc prolongation.
Monitor ECGs and electrolytes, particularly potassium and magnesium, prior to starting KRAZATI, during concomitant use, and as clinically indicated in patients with congestive heart failure, bradyarrhythmias, electrolyte abnormalities, and in patients who are unable to avoid concomitant medications that are known to prolong the QT interval. Correct electrolyte abnormalities. Withhold, reduce the dose, or permanently discontinue KRAZATI depending on severity [see Dosage and Administration (2.3)].
5.3 Hepatotoxicity
KRAZATI can cause hepatotoxicity, which may lead to drug-induced liver injury and hepatitis.
In the pooled safety population of 366 patients [see Adverse Reactions (6.1)] who received single-agent KRAZATI, drug-induced liver injury was reported in 0.3% of patients, including 0.3% Grade 3. A total of 32% of patients who received adagrasib had increased alanine aminotransferase (ALT)/increased aspartate aminotransferase (AST); 5% were Grade 3 and 0.5% were Grade 4. The median time to first onset of increased ALT/AST was 3 weeks (range: 0.1 to 48). Overall hepatotoxicity occurred in 37%, and 7% were Grade 3 or 4. Hepatotoxicity leading to dose interruption or reduction occurred in 12% of patients. Adagrasib was discontinued due to hepatotoxicity in 0.5% of patients.
In patients who received KRAZATI in combination with cetuximab [see Adverse Reactions (6.1)], 29% had increased alanine aminotransferase (ALT)/increased aspartate aminotransferase (AST); 5% were Grade 3 and 1.1% were Grade 4. The median time to first onset of increased ALT/AST was 4 weeks (range: 0.1 to 27). Overall hepatotoxicity occurred in 38%, and 10% were Grade 3 or 4. Hepatotoxicity leading to adagrasib dose interruption or reduction occurred in 12% of patients.
Monitor liver laboratory tests (AST, ALT, alkaline phosphatase and total bilirubin) prior to the start of KRAZATI and monthly for 3 months or as clinically indicated, with more frequent testing in patients who develop transaminase elevations. Reduce the dose, withhold, or permanently discontinue KRAZATI based on severity [see Dosage and Administration (2.3) and Adverse Reactions (6.1)].
5.4 Interstitial Lung Disease / Pneumonitis
KRAZATI can cause interstitial lung disease (ILD)/pneumonitis, which can be fatal.
In the pooled safety population [see Adverse Reactions (6.1)] who received single-agent KRAZATI, ILD/pneumonitis occurred in 4.1% of patients, 1.4% were Grade 3 or 4, and one case was fatal. The median time to first onset for ILD/pneumonitis was 12 weeks (range: 5 to 31 weeks). Adagrasib was discontinued due to ILD/pneumonitis in 0.8% of patients.
In patients who received KRAZATI in combination with cetuximab [see Adverse Reactions (6.1)], Grade 1 ILD/pneumonitis occurred in 1.1% of patients. The time to first onset for ILD/pneumonitis was 38 weeks.
Monitor patients for new or worsening respiratory symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, fever) during treatment with KRAZATI. Withhold KRAZATI in patients with suspected ILD/pneumonitis and permanently discontinue KRAZATI if no other potential causes of ILD/pneumonitis are identified [see Dosage and Administration (2.3)].

7 DRUG INTERACTIONS
7.1 Effects of Other Drugs on KRAZATI
Strong CYP3A4 Inducers
Avoid concomitant use of KRAZATI with strong CYP3A inducers.
Adagrasib is a CYP3A4 substrate. Concomitant use of KRAZATI with a strong CYP3A inducer reduces adagrasib exposure [see Clinical Pharmacology (12.3)], which may reduce the effectiveness of KRAZATI.
Strong CYP3A4 Inhibitors
Avoid concomitant use of KRAZATI with strong CYP3A inhibitors until adagrasib concentrations have reached steady state (after approximately 8 days).
Adagrasib is a CYP3A4 substrate. If adagrasib concentrations have not reached steady state, concomitant use of a strong CYP3A inhibitor will increase adagrasib concentrations, [see Clinical Pharmacology (12.3)], which may increase the risk of KRAZATI adverse reactions.
7.2 Effects of KRAZATI on Other Drugs
Sensitive CYP3A Substrates
Avoid concomitant use of KRAZATI with sensitive CYP3A substrates unless otherwise recommended in the Prescribing Information for these substrates.
Adagrasib is a CYP3A inhibitor. Concomitant use with KRAZATI increases exposure of CYP3A substrates [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions related to these substrates.
Sensitive CYP2C9 Substrates
Avoid concomitant use of KRAZATI with sensitive CYP2C9 substrates where minimal concentration changes may lead to serious adverse reactions unless otherwise recommended in the Prescribing Information for these substrates.
Adagrasib is a CYP2C9 inhibitor. Concomitant use with KRAZATI increases exposure of CYP2C9 substrates [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions related to these substrates.
Sensitive CYP2D6 Substrates
Avoid concomitant use of KRAZATI with sensitive CYP2D6 substrates where minimal concentration changes may lead to serious adverse reactions unless otherwise recommended in the Prescribing Information for these substrates.
Adagrasib is a CYP2D6 inhibitor. Concomitant use with KRAZATI increases exposure of CYP2D6 substrates [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions related to these substrates.
P-gp Substrates
Avoid concomitant use of KRAZATI with P-gp substrates where minimal concentration changes may lead to serious adverse reactions unless otherwise recommended in the Prescribing Information for these substrates.
Adagrasib is a P-gp inhibitor. Concomitant use with KRAZATI increases exposure of P-gp substrates [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions related to these substrates.
7.3 Drugs That Prolong QTc Interval
Avoid concomitant use of KRAZATI with other product(s) with a known potential to prolong the QTc interval. If concomitant use cannot be avoided, monitor electrocardiogram and electrolytes prior to starting KRAZATI, during concomitant use, and as clinically indicated [see Warnings and Precautions (5.2)]. Withhold KRAZATI if the QTc interval is > 500 ms or the change from baseline is > 60 ms [see Dosage and Administration (2.3)].
Adagrasib causes QTc interval prolongation [see Clinical Pharmacology (12.2)]. Concomitant use of KRAZATI with other products that prolong the QTc interval may result in a greater increase in the QTc interval and adverse reactions associated with QTc interval prolongation, including Torsade de pointes, other serious arrythmias, and sudden death [see Warnings and Precautions (5.2)].

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
There are no available data on the use of KRAZATI in pregnant women. In animal reproduction studies, oral administration of adagrasib to pregnant rats and rabbits during the period of organogenesis did not cause adverse development effects or embryo-fetal lethality at exposures below the human exposure at the recommended dose of 600 mg twice daily (see Data).
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data
Animal Data
In a rat embryo-fetal development study, once daily oral administration of adagrasib to pregnant rats during the period of organogenesis resulted in maternal toxicity (reduced body weight and food intake, and adverse clinical signs leading to moribund condition and early termination) and lower fetal body weight at 270 mg/kg dose level (approximately 2 times the recommended dose of 600 mg twice daily based on body surface area [BSA]). Adagrasib induced skeletal malformations, such as bent limbs, and skeletal variations, such as bent scapula, wavy ribs, and supernumerary short cervical ribs at 270 mg/kg, which were secondary to maternal toxicity and reduced fetal body weight.
In a rabbit embryo-fetal development study, once daily oral administration of adagrasib during the period of organogenesis resulted in lower fetal body weight and increased litter frequency of unossified sternebra at 30 mg/kg (approximately 0.11 times the human exposure based on area under the curve [AUC] at the clinical dose of 600 mg twice daily). This skeletal variation was associated with maternal toxicities, including reduced mean body weight and decreased food consumption. Adagrasib exposure did not cause adverse developmental effects and did not affect embryo-fetal survival in rabbits at doses up to 30 mg/kg once daily.
8.2 Lactation
Risk Summary
There are no data on the presence of adagrasib or its metabolites in human milk, the effects on the breastfed child, or on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with KRAZATI and for 1 week after the last dose.
8.3 Females and Males of Reproductive Potential
Infertility
Based on findings from animal studies, KRAZATI may impair fertility in females and males of reproductive potential [see Nonclinical Toxicology (13.1)].
8.4 Pediatric Use
The safety and effectiveness of KRAZATI has not been established in pediatric patients.
8.5 Geriatric Use
Of 116 patients with metastatic NSCLC who received adagrasib 600 mg orally twice daily in KRYSTAL-1, 49% (57 patients) were ≥ 65 years of age and 13% (15 patients) were ≥ 75 years of age. No overall differences in safety or effectiveness were observed between older and younger patients.
Of 94 patients with metastatic CRC who received adagrasib 600 mg orally twice daily in combination with cetuximab in KRISTAL-1, 33% (31 patients) were ≥ 65 years of age and 2.1% (2 patients) were ≥ 75 years of age. No overall differences in safety or effectiveness were observed between older and younger patients.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Adagrasib is an irreversible inhibitor of KRAS G12C that covalently binds to the mutant cysteine in KRAS G12C and locks the mutant KRAS protein in its inactive state that prevents downstream signaling without affecting wild-type KRAS protein. Adagrasib inhibited tumor cell growth and viability in cells harboring KRAS G12C mutations and resulted in tumor regression in KRAS G12C-mutated tumor xenograft models with minimal off-target activity. Adagrasib in combination with cetuximab had increased antitumor activity in some cell line-derived and patient-derived KRAS G12C-mutant CRC tumor xenograft models compared to adagrasib or cetuximab alone.
12.2 Pharmacodynamics
Adagrasib exposure-response relationships and the time course of pharmacodynamic response are unknown.
Cardiac Electrophysiology
Adagrasib increased QTc in a concentration-dependent manner. Based on the concentration-QTcF relationship, the mean (90% CI) QTcF change from baseline (ΔQTcF) was 18 (15, 21) ms at the mean steady-state maximum concentration (Cmax,ss) in patients after administration of adagrasib 600 mg twice daily [see Warnings and Precautions (5.2)].
12.3 Pharmacokinetics
The pharmacokinetics of adagrasib were studied in healthy subjects and in patients with KRAS G12C-mutated NSCLC or CRC. Adagrasib pharmacokinetic data are presented as mean (percent coefficient of variation) unless otherwise specified.
Adagrasib AUC and Cmax increase dose proportionally over the dose range of 400 mg to 600 mg (0.67 to 1 times the approved recommended dose). Adagrasib steady-state was reached within 8 days following administration of the approved recommended dosage and accumulation was approximately 6-fold.
Distribution
The apparent volume of distribution of adagrasib is 942 L (57%). Human plasma protein binding of adagrasib is approximately 98% in vitro.
Elimination
The adagrasib terminal elimination half-life is 23 hours (16%) and the apparent oral clearance (CL/F) is 37 L/h (54%) in patients.
Specific Populations
No clinically significant differences in the pharmacokinetics of adagrasib based on age (19 to 89 years), sex, race (White, Black or African American, or Asian), body weight (36 to 146 kg), ECOG PS (0, 1), tumor type (NSCLC or CRC), or tumor burden. No clinically significant differences in the pharmacokinetics of adagrasib are expected in patients with mild to severe renal impairment (CLcr 15 to < 90 mL/min estimated by Cockcroft-Gault equation) or in patients with mild to severe hepatic impairment (Child-Pugh classes A to C).

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenicity studies have not been conducted with adagrasib.
Adagrasib was not mutagenic in an in vitro bacterial reverse mutation (Ames) assay and was not genotoxic in an in vitro chromosomal aberration assay or an in vivo micronucleus assay in rats.
Fertility studies were not conducted with adagrasib. In toxicology studies of up to 13-weeks in duration in rats, oral administration of adagrasib induced phospholipidosis which increased vacuolation in female reproductive organs, including vacuolation in ovaries (corpora lutea, macrophage or interstitial cells) and uterus (glandular epithelium), and atrophy with mucification of the vaginal mucosa at doses ≥ 150 mg/kg (approximately equal to or greater than the human exposure at the recommended dose based on area under the curve [AUC]). These findings reversed after cessation of dosing in the 28-day study but in the 13-week study, pigmented macrophage aggregates were observed in the ovaries of female rats after the recovery period. In a 28-day repeat-dose toxicology study, oral administration of adagrasib to male rats induced atrophy and epithelial vacuolation of the prostate gland and seminal vesicles at 300 mg/kg (approximately 1.6 times the human exposure at the recommended dose based on AUC). These findings resolved after cessation of treatment.
13.2 Animal Toxicology and/or Pharmacology
Phospholipidosis (vacuolation and/or presence of foamy macrophages) was observed in multiple organs (e.g., lung, trachea, heart, skeletal, ovaries, uterus, adrenal gland, kidney, liver, lymph nodes, spleen, thymus, and thyroid in rats; and heart and lung in dogs) after repeated oral administration of adagrasib in rats and dogs. In toxicology studies of up to 13-week duration in rats, phospholipidosis was observed at doses ≥ 150 mg/kg (approximately ≥ 2 times the human exposure at the recommended dose based on AUC). In a dog 28-day toxicity study, this effect was observed at 25 mg/kg (approximately equal to the human exposure at the recommended dose based on AUC). The extent of vacuolization and the presence of foamy macrophages were more prominent in the rat compared to dogs, and evidence of reversibility after cessation of treatment was noted for most organs. The significance of this finding in humans in unknown.

14 CLINICAL STUDIES
14.1 Non-Small Cell Lung Cancer
The efficacy of adagrasib was evaluated in KRYSTAL-1 (NCT03785249), a multicenter, single-arm, open-label expansion cohort study. Eligible patients were required to have locally advanced or metastatic KRAS G12C-mutated NSCLC who previously received treatment with a platinum-based regimen and an immune checkpoint inhibitor, an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 or 1, and at least one measurable lesion as defined by Response Evaluation criteria in Solid Tumors (RECIST v1.1). Identification of a KRAS G12C mutation was prospectively determined by local testing using tissue specimens. Patients received adagrasib 600 mg orally twice daily until unacceptable toxicity or disease progression. Tumor assessments were performed every 6 weeks. The major efficacy outcome measures were confirmed objective response rate (ORR) and duration of response (DOR) as evaluated by blinded independent central review (BICR) according to RECIST v1.1.
In the efficacy population, KRAS G12C mutation status was determined by prospective local testing using tumor tissue specimens. Of the 112 patients with KRAS G12C mutation, tissue samples from 88% (98/112) patients were tested retrospectively using the QIAGEN therascreen KRAS RGQ PCR Kit. While 89% (87/98) of patients were positive for KRAS G12C mutation, 11% (11/98) did not have a KRAS G12C mutation identified. In addition, plasma samples from 63% (71/112) patients were tested retrospectively using Agilent Resolution ctDx FIRST assay. While 66% (47/71) of patients were positive for KRAS G12C mutation, 34% (24/71) did not have a KRAS G12C mutation identified.
A total of 112 patients had at least one measurable lesion at baseline as assessed by BICR according to RECIST v1.1.
The baseline demographic and disease characteristics in the efficacy population were: median age 64 years (range: 25 to 89), 55% female, 83% White, 8% were Black or African American, 4% Asian, 4% race not reported, 0.9% American Indian or Alaska Native, 16% Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 and 83% ECOG PS 1. Tumor histology was 97% adenocarcinoma and 89% of patients had metastatic disease. Patients received a median of 2 prior systemic therapies (range 1 to 7); 43% received 1 prior line, 35% received 2 prior lines, 10% received 3 prior lines and 12% received 4 or more prior lines, 98% received both prior platinum and prior anti-PD-1/PD-L1 therapy. Sites of extra-thoracic disease included bone 42%, brain 30%, adrenals 21%, and liver 21%.

14.2 Colorectal Cancer
The efficacy of adagrasib in combination with cetuximab was evaluated in KRYSTAL-1, a multicenter, single-arm, open-label expansion cohort study. Eligible patients were required to have locally advanced or metastatic KRAS G12C-mutated CRC and to have previously received therapy with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, a VEGF inhibitor if eligible, and an ECOG PS of 0 or 1.
Patients initiated treatment with adagrasib 600 mg orally twice daily in combination with cetuximab administered either biweekly (77 patients with 500 mg/m2 every two weeks) or weekly (17 patients with 400 mg/m2 initial dose followed by 250 mg/m2 weekly). Treatment continued until unacceptable toxicity or disease progression. Tumor assessments were performed every 6 weeks. Adagrasib discontinuation required cetuximab discontinuation, however patients could continue to receive adagrasib if cetuximab was discontinued [see Dosage and Administration (2.3)]. Six patients continued with adagrasib single agent therapy after discontinuing cetuximab. The length of time these 6 patients received adagrasib alone ranged from 43 days to 3 years. Patient treatment with adagrasib after disease progression continued if a patient was clinically stable and considered to be deriving clinical benefit by the investigator.
The major efficacy outcome measures were confirmed ORR and DOR according to RECIST v1.1 as assessed by BICR.
In the efficacy population, KRAS G12C mutation status was determined by prospective local testing using tumor tissue specimens. Of the 94 patients with KRAS G12C mutation, tissue samples from 79% (74/94) patients were tested retrospectively using the QIAGEN therascreen KRAS RGQ PCR Kit. Of the 74 tissue samples submitted, 81% (60/74) yielded a result with 93% (56/60) positive for KRAS G12C and 7% (4/60) without a KRAS G12C mutation identified.
The baseline demographic and disease characteristics in the efficacy population were: median age 57 years (range: 24 to 75 years), 53% female, 71% White, 14% were Black or African American, 5% Asian, 1.1% American Indian or Alaska Native, 9% reported as other; 51% ECOG PS 0 and 49% ECOG PS 1. Tumor histology was 100% adenocarcinoma and 99% of patients had metastatic disease. Patients received a median of 3 prior systemic therapies (range 1 to 9); 9% received 1 prior line, 36% received 2 prior lines, 31% received 3 prior lines and 25% received 4 or more prior lines. Sites of metastatic disease included lung (71%), liver (64%) and bone (14%).
