re hepatic impairment while taking GILOTRIF, treatment should be discontinued.
5.5 KeratitisKeratitis, characterized as acute or worsening eye inflammation, lacrimation, light sensitivity, blurred vision, eye pain, and/or red eye occurred in 0.8% of patients treated with GILOTRIF among 3865 patients across clinical trials. Keratitis was reported in 5 (2.2%) patients in Study 1, with Grade 3 in 1 (0.4%). Withhold GILOTRIF during eva luation of patients with suspected keratitis, and if diagnosis of ulcerative keratitis is confirmed, treatment with GILOTRIF should be interrupted or discontinued [see Dosage and Administration (2.3)]. If keratitis is diagnosed, the benefits and risks of continuing treatment should be carefully considered. GILOTRIF should be used with caution in patients with a history of keratitis, ulcerative keratitis, or severe dry eye [see Adverse Reactions (6.1)]. Contact lens use is also a risk factor for keratitis and ulceration.
5.6 Embryofetal ToxicityBased on its mechanism of action, GILOTRIF can cause fetal harm when administered to a pregnant woman. Afatinib was embryotoxic and, in animals with maternal toxicity, led to abortions at late gestational stages in rabbits at doses of 5 mg/kg (approximately 0.2 times the human exposure at the recommended dose of 40 mg daily) or greater. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus [see Use in Specific Populations (8.1)].
Advise females of reproductive potential to use highly effective contraception during treatment, and for at least 2 weeks after the last dose of GILOTRIF. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking GILOTRIF [see Use in Specific Populations (8.1 and 8.6)].
6 ADVERSE REACTIONSThe following adverse reactions are discussed in greater detail in other sections of the labeling:
◦Diarrhea [see Warnings and Precautions (5.1)]
◦Bullous and Exfoliative Skin Disorders [see Warnings and Precautions (5.2)]
◦Interstitial Lung Disease [see Warnings and Precautions (5.3)]
◦Hepatic Toxicity [see Warnings and Precautions (5.4)]
◦Keratitis [see Warnings and Precautions (5.5)]
6.1 Clinical 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 safety eva luation of GILOTRIF is based on the data from more than 3800 patients, including 2135 NSCLC patients receiving GILOTRIF monotherapy at or above the recommended dose.
Controlled Study The data in Tables 1 and 2 below reflect exposure of 229 EGFR-TKI naïve GILOTRIF-treated patients with EGFR mutation-positive, metastatic, non-squamous, NSCLC enrolled in a randomized, multicenter, open-label trial (Study 1). Patients received GILOTRIF 40 mg daily until documented disease progression or intolerance to the therapy. A total of 111 patients were treated with pemetrexed/cisplatin. Patients were treated with pemetrexed 500 mg/m² followed after 30 minutes by cisplatin 75 mg/m² every three weeks for a maximum of six treatment courses.
The median exposure was 11.0 months for patients treated with GILOTRIF and 3.4 months f |
