Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in other sections of the labeling: Myopathy and Rhabdomyolysis [see Warnings and Precautions ( 5.1 )]. Immune-Mediated Necrotizing Myopathy [see Warnings and Precautions ( 5.2 )] Hepatic Dysfunction [see Warnings and Precautions ( 5.3 )] Increases in HbA1c and Fasting Serum Glucose Levels [see Warnings and Precautions ( 5.4 )] . The most frequent adverse reactions (rate ≥ 2%) were myalgia, constipation, diarrhea, back pain, and pain in extremity. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Medicure at 1-800-509-0544 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Studies Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of one drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Adverse Reactions in Adults with Primary Hyperlipidemia In 10 controlled clinical studies and 4 subsequent open-label extension studies, 3,291 adult patients with primary hyperlipidemia were administered pitavastatin 1 mg to 4 mg daily. The mean continuous exposure of pitavastatin (1 mg to 4 mg) was 36.7 weeks (median 51.1 weeks). The mean age of the patients was 60.9 years (range; 18 years – 89 years) and 52% females. Approximately 93% of the patients were White 7% were Asian/Indian, 0.2% were African American and 0.3% were Hispanic and other. In controlled clinical studies and their open-label extensions, 3.9% (1 mg), 3.3% (2 mg), and 3.7% (4 mg) of pitavastatin-treated patients were discontinued due to adverse reactions. The most common adverse reactions that led to treatment discontinuation were: elevated creatine phosphokinase (0.6% on 4 mg) and myalgia (0.5% on 4 mg). Adverse reactions reported in ≥ 2% of patients in controlled clinical studies and at a rate greater than or equal to placebo are shown in Table 1. These studies had treatment duration of up to 12 weeks. Table 1. Adverse Reactions (≥ 2% and ≥ placebo) in Adult Patients with Primary Hyperlipidemia and Mixed Dyslipidemia in Studies up to 12 Weeks Adverse Reactions Placebo N=208 % Pitavastatin 1 mg N=309 % Pitavastatin 2 mg N=951 % Pitavastatin 4 mg N=1540 % Myalgia 1.4 1.9 2.8 3.1 Constipation 1.9 3.6 1.5 2.2 Diarrhea 1.9 2.6 1.5 1.9 Back pain 2.9 3.9 1.8 1.4 Pain in extremity 1.9 2.3 0.6 0.9 Other adverse reactions reported from clinical studies were arthralgia, headache, influenza, and nasopharyngitis. Hypersensitivity reactions including rash, pruritus, and urticaria have been reported with pitavastatin. The following laboratory abnormalities have been reported: elevated creatine phosphokinase, transaminases, alkaline phosphatase, bilirubin, and glucose. Adverse Reactions in Adult HIV-Infected Patients with Dyslipidemia In a double-blind, randomized, controlled, 52-week trial, 252 HIV-infected patients with dyslipidemia were treated with either pitavastatin 4 mg once daily (n=126) or another statin (n=126). All patients were taking antiretroviral therapy (excluding darunavir) and had HIV-1 RNA less than 200 copies/mL and CD4 count greater than 200 cell/μL for at least 3 months prior to randomization. The safety profile of pitavastatin was generally consistent with that observed in the clinical trials described above. One patient (0.8%) treated with pitavastatin had a peak creatine phosphokinase value exceeding 10 times the upper limit of normal (ULN), which resolved spontaneously. Four patients (3%) treated with pitavastatin had at least one ALT value exceeding 3 times but less than 5 times the ULN, none of which led to drug discontinuation. Virologic failure was reported for four patients (3%) treated with pitavastatin, defined as a confirmed measurement of HIV-1 RNA exceeding 200 copies/mL that was also more than a 2-fold increase from baseline.

Drug Interactions

7 DRUG INTERACTIONS See full prescribing information for details regarding concomitant use of ZYPITAMAG with other drugs that increase the risk of myopathy and rhabdomyolysis. ( 2.4 , 7 ). Table 2 includes a list of drugs that increase the risk of myopathy and rhabdomyolysis when administered concomitantly with ZYPITAMAG and instructions for preventing or managing drug interactions [see Warnings and Precautions ( 5.1 ), Clinical Pharmacology ( 12.3 )] . Table 2. Drug Interactions that Increase the Risk of Myopathy and Rhabdomyolysis with ZYPITAMAG Cyclosporine Clinical Impact: Cyclosporine significantly increases pitavastatin exposure and increases the risk of myopathy and rhabdomyolysis . Intervention: Concomitant use of cyclosporine with ZYPITAMAG is contraindicated [see Contraindications ( 4 )]. Gemfibrozil Clinical Impact: Gemfibrozil may cause myopathy when given alone. The risk of myopathy and rhabdomyolysis is increased with concomitant use of gemfibrozil with statins, including pitavastatin. Intervention: Avoid concomitant use of gemfibrozil with ZYPITAMAG. Erythromycin Clinical Impact: Erythromycin significantly increases pitavastatin exposure and increases the risk of myopathy and rhabdomyolysis . Intervention: In patients taking erythromycin, do not exceed ZYPITAMAG 1 mg once daily [see Dosage and Administration ( 2.4 )]. Rifampin Clinical Impact: Rifampin significantly increases peak pitavastatin exposure and increases the risk of myopathy and rhabdomyolysis . Intervention: In patients taking rifampin, do not exceed ZYPITAMAG 2 mg once daily [see Dosage and Administration ( 2.4 )]. Fibrates Clinical Impact: Fibrates may cause myopathy when given alone. The risk of myopathy and rhabdomyolysis is increased with concomitant use of fibrates with statins, including pitavastatin. Intervention: Consider if the benefit of using fibrates concomitantly with ZYPITAMAG outweighs the increased risk of myopathy and rhabdomyolysis. Niacin Clinical Impact: The risk of myopathy and rhabdomyolysis may be increased with concomitant use of lipid-modifying doses (1 g/day) of niacin with pitavastatin. Intervention: Consider if the benefit of using lipid-modifying doses (>1 g/day) of niacin concomitantly with ZYPITAMAG outweighs the increased risk of myopathy and rhabdomyolysis. Colchicine Clinical Impact: Cases of myopathy and rhabdomyolysis have been reported with concomitant use of colchicine with statins, including pitavastatin. Intervention: Consider the risk/benefit of concomitant use of colchicine with ZYPITAMAG.

Contraindications

4 CONTRAINDICATIONS ZYPITAMAG is contraindicated in the following conditions: Concomitant use of cyclosporine [see Drug Interactions ( 7 )] . Acute liver failure or decompensated cirrhosis [see Warnings and Precautions ( 5.3 )] Hypersensitivity to pitavastatin or any excipients in ZYPITAMAG. Hypersensitivity reactions including angioedema, rash, pruritus, and urticaria have been reported with pitavastatin [see Adverse Reactions ( 6 )] . Cyclosporine ( 4 , 7 ) Active liver failure or decompensated cirrhosis ( 4 , 5.3 ) Hypersensitivity to pitavastatin or any excipients in ZYPITAMAG ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary Discontinue ZYPITAMAG when pregnancy is recognized. Alternatively, consider the ongoing therapeutic needs of the individual patient. ZYPITAMAG decreases synthesis of cholesterol and possibly other biologically active substances derived from cholesterol; therefore, ZYPITAMAG may cause fetal harm when administered to pregnant patients based on the mechanism of action [see Clinical Pharmacology ( 12.1 )] . In addition, treatment of hyperlipidemia is not generally necessary during pregnancy. Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hyperlipidemia for most patients. Available data from case series and prospective and retrospective observational cohort studies over decades of use with statins in pregnant women have not identified a drug-associated risk of major congenital malformations. Published data from prospective and retrospective observational cohort studies with statin use in pregnant women are insufficient to determine if there is a drug-associated risk of miscarriage (see Data) . In animal reproduction studies, no embryo-fetal toxicity or congenital malformations were observed in pregnant rats or rabbits orally administered pitavastatin during the period of organogenesis at doses that resulted in 22 and 4 times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 4 mg, based on AUC (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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 Human Data A Medicaid cohort linkage study of 1152 statin-exposed pregnant women compared to 886,996 controls did not find a significant teratogenic effect from maternal use of statins in the...

Overdosage

10 OVERDOSAGE No specific treatment for pitavastatin overdose is known. Contact Poison Control (1-800-222-1222) for latest recommendations. Hemodialysis is unlikely to be of benefit due to high protein binding ratio of pitavastatin.
