5 WARNINGS AND PRECAUTIONS • Interstitial Lung Disease (ILD): Permanently discontinue VIZIMPRO if ILD is confirmed. • Diarrhea: Withhold and reduce the dose of VIZIMPRO based on the severity. ( 2.3 , 5.2 ) • Dermatologic Adverse Reactions: Withhold and reduce the dose of VIZIMPRO based on the severity. ( 2.3 , 5.3 ) • Embryo-Fetal Toxicity: VIZIMPRO can cause fetal harm. Advise females of reproductive potential to use effective contraception. ( 5.4 , 8.1 , 8.3 )

5.1Interstitial Lung Disease

(ILD) Severe and fatal ILD/pneumonitis occurred in patients treated with VIZIMPRO and occurred in 0.5% of the 394 VIZIMPRO-treated patients; 0.3% of cases were fatal. Monitor patients for pulmonary symptoms indicative of ILD/pneumonitis. Withhold VIZIMPRO and promptly investigate for ILD in patients who present with worsening of respiratory symptoms which may be indicative of ILD (e.g., dyspnea, cough, and fever).

Permanently discontinue VIZIMPRO if ILD is confirmed .

5.2Diarrhea Severe and

fatal diarrhea occurred in patients treated with VIZIMPRO. Diarrhea occurred in 86% of the 394 VIZIMPRO-treated patients; Grade 3 or 4 diarrhea was reported in 11% of patients and 0.3% of cases were fatal. Withhold VIZIMPRO for Grade 2 or greater diarrhea until recovery to less than or equal to Grade 1 severity, then resume VIZIMPRO at the same or a reduced dose depending on the severity of diarrhea . Promptly initiate anti-diarrheal treatment (loperamide or diphenoxylate hydrochloride with atropine sulfate) for diarrhea.

5.3Dermatologic Adverse Reactions Rash and

exfoliative skin reactions occurred in patients treated with VIZIMPRO. Rash occurred in 78% of the 394 VIZIMPRO-treated patients; Grade 3 or 4 rash was reported in 21% of patients. Exfoliative skin reactions of any severity were reported in 7% of patients. Grade 3 or 4 exfoliative skin reactions were reported in 1.8% of patients.

Withhold VIZIMPRO for persistent Grade 2 or any Grade 3 or 4 dermatologic adverse reaction until recovery to less than or equal to Grade 1 severity, then resume VIZIMPRO at the same or a reduced dose depending on the severity of the dermatologic adverse reaction . The incidence and severity of rash and exfoliative skin reactions may increase with sun exposure. At the time of initiation of VIZIMPRO, initiate use of moisturizers and appropriate measures to limit sun exposure. Upon development of Grade 1 rash, initiate treatment with topical antibiotics and topical steroids.

Initiate oral antibiotics for Grade 2 or more severe dermatologic adverse reactions.

5.4Embryo-Fetal Toxicity Based on

findings from animal studies and its mechanism of action, VIZIMPRO can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, oral administration of dacomitinib to pregnant rats during the period of organogenesis resulted in an increased incidence of post-implantation loss and reduced fetal body weight at doses resulting in exposures near the exposure at the 45 mg human dose. The absence of EGFR signaling has been shown to result in embryolethality as well as post-natal death in animals.

Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with VIZIMPRO and for at least 17 days after the final dose .

None. None.

8.1Pregnancy Risk Summary Based on

findings from animal studies and its mechanism of action, VIZIMPRO can cause fetal harm when administered to a pregnant woman . There are no available data on VIZIMPRO use in pregnant women. In animal reproduction studies, oral administration of dacomitinib to pregnant rats during the period of organogenesis resulted in an increased incidence of post-implantation loss and reduced fetal body weight at doses resulting in exposures near the exposure at the 45 mg human dose . The absence of EGFR signaling has been shown to result in embryolethality as well as post-natal death in animals . Advise pregnant women of the potential risk to a fetus . 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 Daily oral administration of dacomitinib to pregnant rats during the period of organogenesis resulted in an increased incidence of post-implantation loss, maternal toxicity, and reduced fetal body weight at 5 mg/kg/day (approximately 1.2 times the exposure based on area under the curve [AUC] at the 45 mg human dose).

Disruption or depletion of EGFR in mouse models has shown EGFR is critically important in reproductive and developmental processes including blastocyst implantation, placental development, and embryo-fetal/post-natal survival and development. Reduction or elimination of embryo-fetal or maternal EGFR signaling in mice can prevent implantation, and can cause embryo-fetal loss during various stages of gestation (through effects on placental development), developmental anomalies, early death in surviving fetuses, and adverse developmental outcomes in multiple organs in embryos/neonates.

6.1Clinical Trials Experience Because

clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data in the Warnings and Precautions section reflect exposure to VIZIMPRO in 394 patients with first-line or previously treated NSCLC with EGFR exon 19 deletion or exon 21 L858R substitution mutations who received VIZIMPRO at the recommended dose of 45 mg once daily in 4 randomized, active-controlled trials [ARCHER 1050 (N=227), Study A7471009 (N=38), Study A7471011 (N=83), and Study A7471028 (N=16)] and one single-arm trial [Study A7471017 (N=30)]. The median duration of exposure to VIZIMPRO was 10.8 months (range 0.07–68) . The data described below reflect exposure to VIZIMPRO in 227 patients with EGFR mutation-positive, metastatic NSCLC enrolled in a randomized, active-controlled trial (ARCHER 1050 ) ; 224 patients received gefitinib 250 mg orally once daily in the active control arm . Patients were excluded if they had a history of ILD, interstitial pneumonitis, or brain metastases.

The median duration of exposure to VIZIMPRO was 15 months (range 0.07–37). The most common (>20%) adverse reactions in patients treated with VIZIMPRO were diarrhea (87%), rash (69%), paronychia (64%), stomatitis (45%), decreased appetite (31%), dry skin (30%), decreased weight (26%), alopecia (23%), cough (21%), and pruritus (21%). Serious adverse reactions occurred in 27% of patients treated with VIZIMPRO. The most common (≥1%) serious adverse reactions were diarrhea (2.2%) and interstitial lung disease (1.3%).

Dose interruptions occurred in 57% of patients treated with VIZIMPRO. The most frequent (>5%) adverse reactions leading to dose interruptions were rash (23%), paronychia (13%), and diarrhea (10%). Dose reductions occurred in 66% of patients treated with VIZIMPRO. The most frequent (>5%) adverse reactions leading to dose reductions were rash (29%), paronychia (17%), and diarrhea (8%). Adverse reactions leading to permanent discontinuation of VIZIMPRO occurred in 18% of patients.

The most common (>0.5%) adverse reactions leading to permanent discontinuation of VIZIMPRO were: rash (2.6%), interstitial lung disease (1.8%), stomatitis (0.9%), and diarrhea (0.9%). Tables 3 and 4 summarize the most common adverse reactions and laboratory abnormalities, respectively, in ARCHER 1050. ARCHER 1050 was not designed to demonstrate a statistically significant difference in adverse reaction rates for VIZIMPRO or for gefitinib for any adverse reaction or laboratory value listed in Table 3 or 4.
