Study Showed ALIMTA(R) (pemetrexed for injection) Improved Survival in Certain Types of Non-Small Cell Lung CancerPatients with Adenocarcinoma or Large Cell Carcinoma Histologies Achieved Improvement in Overall Survival when Treated with ALIMTA-based Regimen
INDIANAPOLIS, May 28 (HSMN NewsFeed) -- The type of non-small cell lung cancer (NSCLC) patients have may now influence their treatment regimen and, in turn, survival outcome according to the results of a major study published online in the Journal of Clinical Oncology. Publication of the study was announced by Eli Lilly and Company.
The 1,725-patient study, the largest Phase III clinical trial in the first-line NSCLC setting, evaluated ALIMTA® (pemetrexed for injection) plus cisplatin versus GEMZAR® (gemcitabine HCl for injection) plus cisplatin, a standard of treatment in this setting. The trial met its primary endpoint of non-inferiority relative to overall survival.
Additionally, in a pre-planned histological analysis, patients with either adenocarcinoma or large-cell carcinoma had a statistically superior and clinically relevant improvement in overall survival when treated with the pemetrexed regimen in the first-line setting.
In comparison, patients with squamous cell histology were found to have a more favorable overall survival when treated with the gemcitabine regimen.
"While non-small cell lung cancer has typically been treated as one disease, this study confirms that histology, or tumor type, can provide a clue as to which treatment regimen works best for a particular tumor type," said the study's lead author, Giorgio Scagliotti, M.D., Department of Clinical and Biological Sciences Thoracic Oncology Unit, University of Torino, Orbassano, Italy. "If we can tailor the therapy for better results, we are closer to improving outcomes for this terrible disease."
The overall survival of patients treated with either the pemetrexed regimen or gemcitabine regimen was found to be non-inferior, with a median survival of 10.3 months. However, when researchers reviewed survival rates according to histological analysis, it was found that patients with adenocarcinoma achieved 12.6 months of overall median survival when treated with the pemetrexed regimen compared to 10.9 months for those treated with the gemcitabine regimen. Patients with large cell carcinoma who were treated with the pemetrexed regimen achieved 10.4 months of overall median survival versus 6.7 months for those treated with the gemcitabine regimen. Both findings are statistically significant.
Comparatively, patients with squamous cell histology were found to have a more favorable rate of survival when treated with the gemcitabine regimen, achieving 10.8 months of median survival, compared to the 9.4 months for those treated with the pemetrexed regimen. This finding also was statistically significant.
The Phase III, randomized study compared the overall survival between pemetrexed+cisplatin versus gemcitabine+cisplatin in 1,725 chemonaive patients with stage IIIB or IV NSCLC who also exhibited a performance status of 0-1. Patients on the pemetrexed arm (n = 862) were treated with pemetrexed (500 mg/m2) and cisplatin (75 mg/m2) on day one every three weeks for up to six cycles. Patients on the gemcitabine arm (n = 863) were treated with cisplatin (75 mg/m2) on day one and gemcitabine (1250 mg/m2) on days one and eight every three weeks for up to six cycles.
Hematologic grade 3/4 drug-related toxicities - neutropenia, anemia and thrombocytopenia - were significantly lower for patients on the pemetrexed arm (p less than or equal to 0.001). Drug-related grade 3/4 febrile neutropenia (p = 0.002) and alopecia (all grades; p < 0.001) were also significantly less on the pemetrexed arm. However, drug-related grade 3/4 nausea (p = 0.004) was more common in patients treated with pemetrexed. Safety data by histology was generally consistent with the overall safety results.
"In research, we're always looking for a new door to open - a different way of looking at the problem, in the hope of finding a better solution. That's why this study is so important. It has opened a door that points to histology as a way of helping physicians decide which lung cancer treatment may work best for a particular patient," said Richard Gaynor, M.D., vice president of cancer research and global oncology platform leader at Lilly.
Notes to Editor
About Non-Small Cell Lung Cancer (NSCLC)
NSCLC is the most common type of lung cancer and represents 85 to 90 percent of all lung cancers.(1) NSCLC has five-tier staging, starting at 0 and rising to the severity of stage IV.(2) NSCLC can spread through the lymphatic system, penetrating the chest lining, ribs, and the nerves and blood vessels that lead to the arm. The liver, bones and brain are potential targets if the cancerous cells enter the bloodstream.
According to the World Health Organization (WHO) Cancer Report, lung cancer is the world's most common cancer and the leading cause of cancer death for both men and women. More than 1 million people die from lung cancer each year.(3)
NSCLC is defined as a group of histologies, that is, tumor types differentiated by cellular structure. The most common NSCLC histology types are squamous (or epidermoid) carcinoma, adenocarcinoma, and large cell carcinoma. These histologies are often classified together because, to date, approaches to diagnosis, staging, prognosis, and treatment have been similar.(4)

Important Safety Information for ALIMTA
Myelosuppression is usually the dose-limiting toxicity with ALIMTA therapy.
ALIMTA is contraindicated in patients who have a history of severe hypersensitivity reaction to pemetrexed or to any other ingredient used in the formulation.
ALIMTA should not be administered to patients with a creatinine clearance <45 mL/min. One patient with severe renal impairment (creatinine clearance 19 mL/min) who did not receive folic acid and vitamin B12 died of drug-related toxicity following administration of ALIMTA alone.
ALIMTA can suppress bone marrow function, as manifested by neutropenia, thrombocytopenia, and anemia (or pancytopenia).
Patients must be instructed to take folic acid and vitamin B12 with ALIMTA as a prophylaxis to reduce treatment-related hematologic and GI toxicities.
Pregnancy Category D -- ALIMTA may cause fetal harm when administered to a pregnant woman.
Complete blood cell counts, including platelet counts and periodic chemistry tests, should be performed on all patients receiving ALIMTA.
Patients should not begin a new cycle of treatment unless the ANC is greater than or equal to 1500 cells/mm3 and the platelet count is greater than or equal to 100,000 cells/mm3 and creatinine clearance is greater than or equal to 45 mL/min.
Pretreatment with dexamethasone or its equivalent has been reported to reduce the incidence and severity of skin rash.
The effect of third space fluid, such as pleural effusion and ascites, on ALIMTA is unknown.
In patients with clinically significant third space fluid, consideration should be given to draining the effusion prior to ALIMTA administration.
Concomitant administration of nephrotoxic drugs or substances that are tubularly secreted could result in delayed clearance of ALIMTA.
Caution should be used when administering ibuprofen concurrently with ALIMTA to patients with mild to moderate renal insufficiency (creatinine clearance from 45 to 79 mL/min). Patients with mild to moderate renal insufficiency should avoid taking NSAIDs with short elimination half-lives for a period of 2 days before, the day of, and 2 days following administration of ALIMTA. In the absence of data regarding potential interaction between ALIMTA and NSAIDs with longer half-lives, all patients taking these NSAIDs should interrupt dosing for at least 5 days before, the day of, and 2 days following ALIMTA administration. If concomitant administration of an NSAID is necessary, patients should be monitored closely for toxicity, especially myelosuppression, renal and gastrointestinal toxicities.
It is recommended that nursing be discontinued if the mother is being treated with ALIMTA.
ALIMTA should be administered under the supervision of a qualified physician experienced in the use of antineoplastic agents.
Dose adjustments may be necessary in patients with hepatic insufficiency.
Dosing and Modification Guidelines
Dose adjustments at the start of a subsequent cycle should be based on nadir hematologic counts or maximum nonhematologic toxicity from the preceding cycle of therapy. Modify or suspend therapy according to the Dosage Reduction Guidelines in the full Prescribing Information.

Important Safety Information for GEMZAR
Myelosuppression is usually the dose-limiting toxicity with GEMZAR therapy.
Known hypersensitivity to GEMZAR.
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.
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.
