Non-Small Cell Lung Cancer

GEMZAR is indicated in combination with cisplatin for the first-line treatment of patients with inoperable, locally advanced (stage IIIA or IIIB), or metastatic (stage IV) non-small cell lung cancer.

About Lung Cancer

According to the American Cancer Society (ACS), lung cancer (both small cell and non-small cell) is the leading cause of cancer death for both men and women. Lung cancer claims more lives than colon, breast, and prostate cancers combined — although fewer than 3% of all cases are found in people under the age of 45. The average age at the time of diagnosis is about 71.1

Lung cancer is the leading cause of cancer death for both men and women in the United States.1

The ACS estimates that in 2009, lung cancer will account for around 29% of all cancer deaths. There will be more than 219,000 new cases of lung cancer in the United States, and approximately 159,000 people will die of this disease: 89,000 men and 70,000 women.1

The average lifetime chance that a man will develop lung cancer is about 1 in 13; for a woman it is 1 in 16. Men who smoke are about 23 times more likely to develop lung cancer than men who are nonsmokers; women who smoke are about 13 times more likely compared to women who are nonsmokers.2 Survival rates for people with lung cancer vary depending on the stage (extent) of the cancer when it is diagnosed.1 For more information about the staging of lung cancer and survival rates, click here.

Myelosuppression is usually the dose-limiting toxicity with GEMZAR therapy.

Indications and Important Safety Information for GEMZAR

Indications

GEMZAR in combination with carboplatin is indicated for the treatment of patients with advanced ovarian cancer that has relapsed at least 6 months after completion of platinum-based therapy.

GEMZAR is indicated in combination with cisplatin for the first-line treatment of patients with inoperable, locally advanced (stage IIIA or IIIB), or metastatic (stage IV) non-small cell lung cancer.

GEMZAR in combination with paclitaxel is indicated for the first-line treatment of patients with metastatic breast cancer after failure of prior anthracycline-containing adjuvant chemotherapy, unless anthracyclines were clinically contraindicated.

GEMZAR is indicated as first-line treatment for patients with locally advanced (nonresectable stage II or stage III) or metastatic (stage IV) adenocarcinoma of the pancreas. GEMZAR is indicated for patients previously treated with 5-FU.

Important Safety Information

Myelosuppression is usually the dose-limiting toxicity with GEMZAR therapy.

Contraindication

Known hypersensitivity to GEMZAR.

Warnings

Infusion times of GEMZAR longer than 60 minutes and more frequent than weekly dosing have been shown to increase toxicity.

Pulmonary toxicity has been reported. In cases of severe lung toxicity, GEMZAR therapy should be discontinued immediately and appropriate supportive care measures instituted.

Hemolytic Uremic Syndrome (HUS) and/or renal failure have been reported following one or more doses of GEMZAR. Renal failure leading to death or requiring dialysis, despite discontinuation of therapy, has been rarely reported. The majority of the cases of renal failure leading to death were due to HUS.

Serious hepatotoxicity, including liver failure and death, has been reported very rarely in patients receiving GEMZAR alone or in combination with other potentially hepatotoxic drugs.

GEMZAR is Pregnancy Category D. GEMZAR can cause fetal harm when administered to a pregnant woman.

Precautions

Use caution in patients with pre-existing renal impairment or hepatic insufficiency. Administration of GEMZAR may exacerbate underlying hepatic insufficiency.

The optimum regimen for safe administration of GEMZAR with therapeutic doses of radiation has not yet been determined in all tumor types. GEMZAR has radiosensitizing activity and radiation recall reactions have been reported.

It is not known whether GEMZAR or its metabolites are excreted in human milk.

The effectiveness of GEMZAR in pediatric patients has not been demonstrated. The toxicities of GEMZAR observed in pediatric patients were similar to those reported in adults.

GEMZAR clearance is affected by age as well as gender.

Patients receiving therapy with GEMZAR should be monitored closely by a physician experienced in the use of cancer chemotherapeutic agents.

Monitoring and Dosage Modifications

Dosage adjustments for hematologic toxicity may be required.

Serum creatinine, potassium, calcium, and magnesium should be monitored during combination therapy with cisplatin.

Patients should be assessed with a CBC, including differential and platelet count, prior to each dose of GEMZAR. Modify or suspend therapy according to the Dosage Reduction Guidelines in the full Prescribing Information.

Hepatic and renal function (including transaminases and serum creatinine) should be evaluated prior to therapy with GEMZAR and periodically thereafter.

Abbreviated Adverse Events (% incidence) for GEMZAR in Advanced Recurrent Ovarian Cancer
