GEMCITABINE

5 WARNINGS AND PRECAUTIONS Schedule-dependent toxicity: Increased toxicity with infusion time greater than 60 minutes or dosing more frequently than once weekly. ( 5.1 ) Myelosuppression: Monitor for myelosuppression prior to each cycle and reduce or withhold dose for severe myelosuppression. ( 5.2 , 5.7 ) Pulmonary toxicity and respiratory failure: Discontinue Gemcitabine Injection for unexplained dyspnea or other evidence of severe pulmonary toxicity. ( 5.3 ) Hemolytic-uremic syndrome (HUS): Monitor renal function prior to initiation and during therapy. Discontinue Gemcitabine Injection for HUS or severe renal impairment. ( 5.4 ) Hepatoxicity: Monitor hepatic function prior to initiation and during therapy. Discontinue Gemcitabine Injection for severe hepatic toxicity. ( 5.5 ) Embryo-Fetal toxicity: Can cause fetal harm. Advise females and males of reproductive potential to use effective contraception. ( 5.6 , 8.1 ) Exacerbation of radiation therapy toxicity: May cause severe and life-threatening toxicity when administered during or within 7 days of radiation therapy. ( 5.7 ) Capillary leak syndrome: Discontinue Gemcitabine Injection. ( 5.8 ) Posterior reversible encephalopathy syndrome (PRES): Discontinue Gemcitabine Injection. ( 5.9 ) 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 dosing schedule [see Dosage and Administration ( 2.1 , 2.2 , 2.3 , and 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 Gemcitabine Injection dosage as recommended [see Dosage and Administration ( 2.1 , 2.2 , 2.3 , and 2.4 )] . 5.3 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 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 have any evidence of pulmonary toxicity. 5.4 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 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 discontinuation of therapy. 5.5 Hepatic Toxicity Drug-induced liver injury, including liver failure and death, has been reported in patients receiving gemcitabine alone or in combination with other potentially hepatotoxic drugs [see Adverse Reactions ( 6.1 and 6.2 )] . Administration of gemcitabine in patients with concurrent hepatic metastases or a pre-existing medical history or 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 that develop severe liver injury. 5.6 Embryofetal 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. Advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 3 months following the final dose [see Use in Specific Populations ( 8.1 ), ( 8.3 )] . 5.7 Exacerbation of Radiation Therapy Toxicity Gemcitabine is not recommended for use in combination with radiation therapy. Concurrent (given together or ≤7 days apart) Life-threatening mucositis, especially esophagitis and pneumonitis occurred in a trial in which gemcitabine was administered at a dose of 1000 mg/m 2 to patients with non-small cell lung cancer for up to 6 consecutive weeks concurrently with thoracic radiation. Non-concurrent (given >7 days apart) Excessive toxicity has not been observed when gemcitabine is administered more than 7 days before or after radiation. Radiation recall has been reported in patients who receive gemcitabine after prior radiation. 5.8 Capillary Leak Syndrome Capillary leak syndrome (CLS) with severe consequences has been reported in patients receiving gemcitabine as a single agent or in combination with other chemotherapeutic agents [see Adverse Reactions ( 6.2 )] . Permanently discontinue Gemcitabine Injection if CLS develops during therapy. 5.9 Posterior Reversible Encephalopathy Syndrome Posterior reversible encephalopathy syndrome (PRES) has been reported in patients receiving gemcitabine as a single agent or in combination with other chemotherapeutic agents [see Adverse Reactions ( 6.2 )] . PRES can present with headache, seizure, lethargy, hypertension, confusion, blindness, and other visual and neurologic disturbances. Confirm the diagnosis of PRES with magnetic resonance imaging (MRI). Permanently discontinue Gemcitabine Injection if PRES develops during therapy.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity [see Contraindications ( 4 )] Schedule-Dependent Toxicity [see Warnings and Precautions ( 5.1 )] Myelosuppression [see Warnings and Precautions ( 5.2 )] Pulmonary Toxicity and Respiratory Failure [see Warnings and Precautions ( 5.3 )] Hemolytic Uremic Syndrome [see Warnings and Precautions ( 5.4 )] Hepatic Toxicity [see Warnings and Precautions ( 5.5 )] Exacerbation of Radiation Therapy Toxicity [see Warnings and Precautions ( 5.7 )] Capillary Leak Syndrome [see Warnings and Precautions ( 5.8 )] Posterior Reversible Encephalopathy Syndrome [see Warnings and Precautions ( 5.9 )] The most common adverse reactions for the single agent (≥20%) are nausea/vomiting, anemia, increased aspartate aminotransferase (AST), increased alanine aminotransferase (ALT), neutropenia, increased alkaline phosphatase, proteinuria, fever, hematuria, rash, thrombocytopenia, dyspnea, and edema.

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 the 979 patients were anemia, thrombocytopenia, hepatic dysfunction, renal dysfunction, nausea/vomiting, fever, rash, dyspnea, hemorrhage, infection, stomatitis, somnolence, flu-like syndrome, and edema. Tables 5 and 6 present the incidence of selected adverse reactions and laboratory abnormalities reported in patients with various malignancies receiving single agent gemcitabine across 5 clinical trials.

Non-Small Cell Lung Cancer: Table 11 and 12 present the incidence of selected adverse reactions and laboratory abnormalities occurring in ≥10% of gemcitabine-treated patients and at a higher incidence in the gemcitabine with cisplatin arm, reported in a randomized trial (Study 3) of gemcitabine with cisplatin (n=260) administered in 28-day cycles as compared to cisplatin alone (n=262) in patients receiving first-line treatment for locally advanced or metastatic NSCLC [see Clinical Studies ( 14.3 )] . Patients randomized to gemcitabine with cisplatin received a median of 4 cycles of treatment and those randomized to cisplatin alone received a median of 2 cycles of treatment. In this trial, the requirement for dose adjustments (>90% versus 16%), discontinuation of treatment for adverse reactions (15% versus 8%), and the proportion of patients hospitalized (36% versus 23%) were all higher for patients receiving gemcitabine with cisplatin compared to those receiving cisplatin alone. The incidence of febrile neutropenia (3% versus <1%), sepsis (4% versus 1%), Grade 3 cardiac dysrhythmias (3% versus <1%) were all higher in the gemcitabine with cisplatin arm compared to the cisplatin alone arm. The two-drug combination was more myelosuppressive with 4 (1.5%) possibly treatment-related deaths, including 3 resulting from myelosuppression with infection and one case of renal failure associated with pancytopenia and infection. No deaths due to treatment were reported on the cisplatin arm.

Additional clinically significant adverse reactions are provided following Table 14. Patients in the gemcitabine/ cisplatin (GC) arm received a median of 5 cycles and those in the etoposide/ cisplatin (EC) arm received a median of 4 cycles. The majority of patients receiving more than one cycle of treatment required dose adjustments; 81% in the (GC) arm and 68% in the (EC) arm. The incidence of hospitalizations for adverse reactions was 22% in the GC arm and 27% in the EC arm. The proportion of patients who discontinued treatment for adverse reactions was higher in the GC arm (14% versus 8%). The proportion of patients who were hospitalized for febrile neutropenia was lower in the GC arm (7% versus 12%). There was one death attributed to treatment, a patient with febrile neutropenia and renal failure, which occurred in the GC arm.
