• Embryo-Fetal Toxicity: Can cause fetal harm. Advise females and males of reproductive potential to use effective contraception. ( 5.7 , 8.1 )
• Exacerbation of Radiation Therapy Toxicity: May cause severe and life-threatening toxicity when administered during or within 7 days of radiation therapy. ( 5.8 )
• Capillary Leak Syndrome: Discontinue Gemcitabine Injection. ( 5.9 )
• Posterior Reversible Encephalopathy Syndrome (PRES): Discontinue Gemcitabine Injection. ( 5.10 ) 5.1 Schedule-Dependent Toxicity In clinical trials evaluating the maximum tolerated dose of gemcitabine, prolongation of the infusion time beyond 60 minutes or more frequent than weekly dosing resulted in an increased incidence of clinically significant hypotension, severe flu-like symptoms, myelosuppression, and asthenia. The half-life of gemcitabine is influenced by the length of the infusion [see Clinical Pharmacology (12.3) ] . Refer to the recommended Gemcitabine Injection dosage [see Dosage and Administration (2.1 , 2.2 , 2.3 , 2.4) ] . 5.2 Myelosuppression Myelosuppression manifested by neutropenia, thrombocytopenia, and anemia, occurs with gemcitabine as a single agent and the risks are increased when gemcitabine is combined with other cytotoxic drugs. In clinical trials, Grade 3–4 neutropenia, anemia, and thrombocytopenia occurred in 25%, 8%, and 5%, respectively of the 979 patients who received single agent gemcitabine. The frequencies of Grade 3–4 neutropenia, anemia, and thrombocytopenia varied from 48% to 71%, 8% to 28%, and 5% to 55%, respectively, in patients receiving gemcitabine in combination with another drug [see Adverse Reactions (6.1) ] . Prior to each dose of Gemcitabine Injection, obtain a complete blood count (CBC) with a differential and a platelet count. Modify the dosage as recommended [see Dosage and Administration (2.1 , 2.2 , 2.3 , 2.4) ] . 5.3 Severe Cutaneous Adverse Reactions (SCARs) SCARs, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), which can be life-threatening or fatal, have been reported in association with gemcitabine treatment [see Adverse Reactions (6.2) ] . Monitor patients for signs and symptoms of severe cutaneous adverse reactions. Permanently discontinue gemcitabine in patients who develop SCARs. 5.4 Pulmonary Toxicity and Respiratory Failure Pulmonary toxicity, including interstitial pneumonitis, pulmonary fibrosis, pulmonary edema, and adult respiratory distress syndrome (ARDS), has been reported. In some cases, these pulmonary events can lead to fatal respiratory failure despite the discontinuation of therapy. The onset of pulmonary symptoms may occur up to 2 weeks after the last dose of gemcitabine [see Adverse Reactions (6.1 , 6.2) ] . Permanently discontinue Gemcitabine Injection in patients who develop unexplained dyspnea, with or without bronchospasm, or evidence of severe pulmonary toxicity. 5.5 Hemolytic Uremic Syndrome Hemolytic uremic syndrome (HUS), including fatalities from renal failure or the requirement for dialysis, can occur with gemcitabine. In clinical trials, HUS occurred in 0.25% of 2429 patients. Most fatal cases of renal failure were due to HUS [see Adverse Reactions (6.1) ]. Serious cases of thrombotic microangiopathy (TMA) other than HUS have been reported with gemcitabine [see Adverse Reactions (6.2) ]. Assess renal function prior to initiation of Gemcitabine Injection and periodically during treatment. Consider the diagnosis of HUS in patients who develop anemia with evidence of microangiopathic hemolysis; increased bilirubin or LDH; reticulocytosis; severe thrombocytopenia; or evidence of renal failure (increased serum creatinine or BUN) . Permanently discontinue Gemcitabine Injection in patients with HUS or severe renal impairment. Renal failure may not be reversible even with the discontinuation of therapy. 5.6 Hepatic Toxicity Drug-induced liver injury, including liver failure and death, has been reported in patients receiving gemcitabine alone or with other potentially hepatotoxic drugs [see Adverse Reactions (6.1 , 6.2) ]. Administration of gemcitabine in patients with concurrent liver metastases or a pre-existing medical history of hepatitis, alcoholism, or liver cirrhosis can lead to exacerbation of the underlying hepatic insufficiency . Assess hepatic function prior to initiation of Gemcitabine Injection and periodically during treatment. Permanently discontinue Gemcitabine Injection in patients who develop severe hepatic toxicity. 5.7 Embryo-Fetal Toxicity Based on animal data and its mechanism of action, Gemcitabine Injection can cause fetal harm when administered to a pregnant woman. Gemcitabine was teratogenic, embryotoxic, and fetotoxic in mice and rabbits. Advise pregnant women of the potential risk to a fetus . Advise females of reproductive potential to use effective contraception during treatment with Gemcitabine Injection and for 6 months after the final dose.

Single Agent The data described below reflect exposure to gemcitabine as a single agent administered at doses between 800 mg/m 2 to 1250 mg/m 2 intravenously over 30 minutes once weekly, in 979 patients with various malignancies. The most common (≥20%) adverse reactions of single agent gemcitabine are nausea/vomiting, anemia, increased alanine aminotransferase (ALT), increased aspartate aminotransferase (AST), neutropenia, increased alkaline phosphatase, proteinuria, fever, hematuria, rash, thrombocytopenia, dyspnea, and edema. The most common (≥5%) Grade 3 or 4 adverse reactions were neutropenia, nausea/vomiting, increased ALT, increased alkaline phosphatase, anemia, increased AST, and thrombocytopenia. Approximately 10% of the 979 patients discontinued gemcitabine due to adverse reactions. Adverse reactions resulting in discontinuation of gemcitabine in 2% of 979 patients were cardiovascular adverse reactions (myocardial infarction, cerebrovascular accident, arrhythmia, and hypertension) and adverse reactions resulting in discontinuation of gemcitabine in < 1% of 979 patients were anemia, thrombocytopenia, hepatic dysfunction, renal dysfunction, nausea/vomiting, fever, rash, dyspnea, hemorrhage, infection, stomatitis, somnolence, flu-like syndrome, and edema.

Additional clinically significant adverse reactions, occurring in <10% of patients, are provided following Table 8. The proportion of patients with dose adjustments for carboplatin (1.8% versus 3.8%), doses of carboplatin omitted (0.2% versus 0) and discontinuing treatment for adverse reactions (11% versus 10%), were similar between arms. Dose adjustment for gemcitabine occurred in 10% of patients and gemcitabine dose was omitted in 14% of patients in the gemcitabine/carboplatin arm.
Use in specific populations
Lactation: Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on animal data and its mechanism of action, Gemcitabine Injection can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ]. There are no available data on the use of gemcitabine in pregnant women. In animal reproduction studies, gemcitabine was teratogenic, embryotoxic, and fetotoxic in mice and rabbits (see Data ) . Advise pregnant women of the potential risk to a fetus [see Use in Specific Populations (8.3) ] . In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Data Animal Data Gemcitabine is embryotoxic in mice. Daily dosing of gemcitabine to pregnant mice increased the incidence of fetal malformations (cleft palate, incomplete ossification) at doses of 1.5 mg/kg/day [about 0.005 times the 1000 mg/m 2 clinical dose based on body surface area (BSA)]. Gemcitabine is embryotoxic and fetotoxic in rabbits. Daily dosing of gemcitabine to pregnant rabbits resulted in fetotoxicity (decreased fetal viability, reduced litter sizes and developmental delays) and increased the incidence of fetal malformations (fused pulmonary artery, absence of gall bladder) at doses of 0.1 mg/kg/day (about 0.002 times the 1000 mg/m 2 clinical dose based on BSA). 8.2 Lactation Risk Summary There is no information regarding the presence of gemcitabine or its metabolites in human milk, or their effects on the breastfed infant or on milk production. Due to the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment with Gemcitabine Injection and for at least one week following the last dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating Gemcitabine Injection [see Use in Specific Populations (8.1) ] . Contraception Gemcitabine Injection can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ]. Females Because of the potential for genotoxicity, advise females of reproductive potential to use effective contraception during treatment with Gemcitabine Injection and for 6 months after the final dose. Males Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment with Gemcitabine Injection and for 3 months after the final dose [see Nonclinical Toxicology (13.1) ]. Infertility Males Based on animal studies, gemcitabine may impair fertility in males of reproductive potential [see Nonclinical Toxicology (13.1) ]. It is not known whether these effects on fertility are reversible. 8.4 Pediatric Use The safety and effectiveness of gemcitabine have not been established in pediatric patients. The safety and pharmacokinetics of gemcitabine were evaluated in a trial in pediatric patients with refractory leukemia. The maximum tolerated dose was 10 mg/m 2 /min for 360 minutes weekly for three weeks followed by a one-week rest period. The safety and activity of gemcitabine were evaluated in a trial of pediatric patients with relapsed acute lymphoblastic leukemia (22 patients) and acute myelogenous leukemia (10 patients) at a dose of 10 mg/m 2 /min administered over 360 minutes weekly for three weeks followed by a one-week rest period. Patients with M1 or M2 bone marrow on Day 28 who did not experience unacceptable toxicity were eligible to receive a maximum of one additional four-week course. Toxicities observed included myelosuppression, febrile neutropenia, increased serum transaminases, nausea, and rash/desquamation. No meaningful clinical activity was observed in this trial. 8.5 Geriatric Use In clinical studies which enrolled 979 patients with various malignancies who received single agent gemcitabine, no overall differences in safety were observed between patients aged 65 and older and younger patients, with the exception of a higher rate of Grade 3–4 thrombocytopenia in older patients as compared to younger patients. In a randomized trial in women with ovarian cancer (Study 1), 175 women received gemcitabine with carboplatin, of which 29% were age 65 years or older. Similar effectiveness was observed between older and younger women. There was significantly higher Grade 3–4 neutropenia in women 65 years of age or older [see Dosage and Administration (2.1) ] . Gemcitabine clearance is affected by age; however, there are no recommended dose adjustments based on patients' age [see Clinical Pharmacology (12.3) ] . 8.6 Gender Gemcitabine clearance is decreased in females [see Clinical Pharmacology (12.3) ]. In single agent studies of gemcitabine, women, especially older women, were more likely not to proceed to a subsequent cycle and to experience Grade 3–4 neutropenia and thrombocytopenia [see Dosage and Administration (2.1 , 2.2 , 2.3 , 2.4) ] .
Pregnancy

Gemcitabine clearance is affected by age; however, there are no recommended dose adjustments based on patients' age [see Clinical Pharmacology (12.3) ] .
Overdosage
There is no known antidote for overdoses of gemcitabine. Myelosuppression, paresthesias, and severe rash were the principal toxicities seen when a single dose as high as 5700 mg/m 2 was administered by intravenous infusion over 30 minutes every 2 weeks to several patients in a dose-escalation study. In the event of suspected overdose, monitor with appropriate blood counts and provide supportive therapy, as necessary.
Description
Gemcitabine is a nucleoside metabolic inhibitor. The chemical name of gemcitabine HCl is 2´-deoxy-2´,2´-difluorocytidine monohydrochloride (β-isomer). The structural formula is as follows: Gemcitabine HCl is a white to off-white solid with a molecular formula of C 9 H 11 F 2 N 3 O 4 ∙HCl and a molecular weight of 299.66 g/mol. It is soluble in water, slightly soluble in methanol, and practically insoluble in ethanol and polar organic solvents. Gemcitabine Injection is a sterile solution in single-dose vials for intravenous use. Each vial contains 200 mg, 1 g, or 2 g of gemcitabine equivalent to 227.7 mg, 1.139 g, or 2.227 g of gemcitabine HCl. Each mL contains 38 mg of gemcitabine free base in Water for Injection equivalent to 43.27 mg of gemcitabine HCl. Hydrochloric acid and/or sodium hydroxide may have been added for pH adjustment. Chemical Structure
Mechanism of action
12.1 Mechanism of Action Gemcitabine kills cells undergoing DNA synthesis and blocks the progression of cells through the G1/S-phase boundary. Gemcitabine is metabolized by nucleoside kinases to diphosphate (dFdCDP) and triphosphate (dFdCTP) nucleosides. Gemcitabine diphosphate inhibits ribonucleotide reductase, an enzyme responsible for catalyzing the reactions that generate deoxynucleoside triphosphates for DNA synthesis, resulting in reductions in deoxynucleotide concentrations, including dCTP. Gemcitabine triphosphate competes with dCTP for incorporation into DNA. The reduction in the intracellular concentration of dCTP by the action of the diphosphate enhances the incorporation of gemcitabine triphosphate into DNA (self-potentiation). After the gemcitabine nucleotide is incorporated into DNA, only one additional nucleotide is added to the growing DNA strands which eventually results in the initiation of apoptotic cell death.
