Como funciona

12.1 Mechanism of Action Ensartinib is a kinase inhibitor of anaplastic lymphoma kinase (ALK) and inhibits other kinases including MET and ROS1. In vitro, ensartinib inhibited phosphorylation of ALK and its downstream signaling proteins AKT, ERK, and S6, thereby blocking ALK-mediated signaling pathways and inhibiting proliferation in cell lines harboring ALK fusions and mutations. In vivo, ensartinib showed anti-tumor activity in a mouse xenograft model of human NSCLC harboring an ALK fusion.

Advise patients to limit direct sun exposure while taking ENSACOVE and for at least 1 week after discontinuation. Withhold, reduce the dose, or permanently discontinue ENSACOVE based on the severity of the adverse reaction [see Dosage and Administration ( 2.4 )]. 5.4 Bradycardia ENSACOVE can cause symptomatic bradycardia. In the pooled safety population [see Adverse Reactions ( 6.1 )], bradycardia (heart rate less than 60 beats per minute) occurred in 6% of patients treated with ENSACOVE. All bradycardia events were Grade 1 or 2. Bradycardia requiring dose reduction occurred in 0.2% and led to dose interruption in 0.4% of ENSACOVE-treated patients. Monitor heart rate regularly during treatment with ENSACOVE. Withhold, reduce the dose, or permanently discontinue ENSACOVE based on severity [see Dosage and Administration ( 2.4 )] . 5.5 Hyperglycemia ENSACOVE can cause hyperglycemia. In the pooled safety population [see Adverse Reactions ( 6.1 )], based on laboratory data, 44% of patients receiving ENSACOVE experienced increased blood glucose, including Grade 3 in 2.5%. The median time to onset of increased blood glucose was 5.9 weeks (0.4 weeks to 3.4 years). Assess fasting serum glucose at baseline and monitor serum glucose periodically during treatment with ENSACOVE. Withhold, reduce the dose, or permanently discontinue ENSACOVE based on severity [see Dosage and Administration ( 2.4 )]. 5.6 Visual Disturbances ENSACOVE can cause visual disturbances including blurred vision, diplopia, photopsia, vitreous floaters, visual impairment, visual field defect, and reduced visual acuity. In the pooled safety population [see Adverse Reactions ( 6.1 )], 8% of patients receiving ENSACOVE experienced visual disturbance, including 0.2% Grade 3. Visual disturbances led to dose interruption in 0.4% of patients. Obtain an ophthalmologic evaluation in patients with new or worsening visual symptoms during treatment with ENSACOVE. Withhold, reduce the dose, or permanently discontinue ENSACOVE based on severity [see Dosage and Administration ( 2.4 )]. 5.7 Increased Creatine Phosphokinase In the pooled safety population [see Adverse Reactions ( 6.1 )], of the 203 patients with creatine phosphokinase (CPK) laboratory data available, increased CPK occurred in 43% of patients who received ENSACOVE. The incidence of Grade 3 increased CPK was 1.5% and 0.5% were Grade 4. The median time to onset of increased CPK was 123 days (range: 13 days to 22 months). Increased CPK leading to dose interruption occurred in 0.2% and dose reduction in 0.4%. Advise patients to report any unexplained muscle pain, tenderness, or weakness. Monitor CPK levels during treatment with ENSACOVE. Withhold, reduce the dose, or permanently discontinue ENSACOVE based on severity [see Dosage and Administration ( 2.4 ), Adverse Reactions ( 6.1 )]. 5.8 Hyperuricemia ENSACOVE can cause hyperuricemia. In the pooled safety population [see Adverse Reactions ( 6.1 )], based on adverse reactions, 6% of patients experienced hyperuricemia, with 0.4% Grade 3 and 0.7% Grade 4. Nine patients (1.9%) required hydration and two patients (0.4%) required urate-lowering medication. Monitor serum uric acid levels prior to initiating ENSACOVE and periodically during treatment. Initiate treatment with urate-lowering medications as clinically indicated. Withhold, reduce the dose, or permanently discontinue ENSACOVE based on severity [see Dosage and Administration ( 2.4 )]. 5.9 Embryo-Fetal Toxicity Based on findings from animal studies and its mechanism of action, ENSACOVE can cause fetal harm when administered to a pregnant woman. In embryo-fetal developmental studies, oral administration of ensartinib to pregnant rats during the period of organogenesis caused adverse developmental outcomes, including embryo-fetal mortality, alterations to growth, and structural abnormalities. Adverse embryo-fetal findings were seen at maternal exposures approximately equivalent to the human exposure at the recommended dose of 225 mg/day based on area under the curve (AUC). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with ENSACOVE and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with ENSACOVE and for 1 week after the last dose [see Use in Specific Populations ( 8.1 , 8.3 ) and Clinical Pharmacology ( 12.1 )]. 5.10 FD&C Yellow No. 5 (Tartrazine) This product contains FD&C Yellow No. 5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons. Although the overall incidence of FD&C Yellow No. 5 (tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity.
