Updated Analysis in Second-Line Treatment of Lung Cancer Trial Confirms Similar Survival for Alimta(R) and DocetaxelAlimta Also Shows Tolerability as Triplet Combination Treatment in First-Line Lung Cancer
ATLANTA, June 4 (HSMN NewsFeed) -- Data presented today at the 42nd American Society of Clinical Oncology (ASCO) annual meeting in Atlanta, Ga., affirms that ALIMTA® (pemetrexed), manufactured and marketed by Eli Lilly and Company, offers patients with advanced non-small cell lung cancer (NSCLC) similar overall survival as docetaxel (Taxotere®).
The survival data were part of a large (n=571), randomized Phase III study to evaluate the efficacy and safety profile of Alimta as second-line therapy in NSCLC. First reported in 2003(i), the study found that patients in the Alimta arm achieved 8.3 months of median survival, whereas those in the docetaxel arm obtained 7.9 months. This updated analysis of data tracked patients from the same study nearly two years beyond the conclusion of the original study and found similar results. The updated data showed that patients who received Alimta experienced 8.3 months of median survival compared to 8.0 months for those in the docetaxel arm.
"The data mirror previously reported results and confirm the efficacy of Alimta versus docetaxel," said Filippo de Marinis, M.D., director of the Pulmonary-Oncology Unit at San Camillo-Forlanini High Specialization Hospitals in Rome, Italy, and one of the study's principal investigators. "Based on these data, and on its safety advantage, Alimta should be regarded as a standard of care for non-small cell lung cancer patients in the second-line setting."
Patients in both arms of the trial were given standard doses of therapy for NSCLC. On day one of a 21-day cycle, patients in the Alimta arm of the trial received Alimta (500 mg/m squared), which was supplemented with vitamin B12 and folic acid as per label instructions. A team of researchers led by Lilly discovered that this vitamin supplementation given with Alimta significantly reduces the frequency and severity of the drug's side effects without compromising its ability to kill cancer cells. Patients in the docetaxel arm were given a 75 mg/m squared infusion.
As previously reported, the incidence of severe neutropenia, a decrease in the number of white blood cells that increases the risk of infection, was five percent in the Alimta arm and 40 percent in the docetaxel arm, an eight-fold difference that was statistically significant (p= <0.001). The difference in the incidence of neutropenic fever and subsequent hospitalizations between the Alimta and docetaxel arms was also statistically significant: two percent for the Alimta patients compared to 13 percent for the docetaxel patients (p= <0.001).
In a third finding that reached statistical significance, the incidence of drug-related serious adverse events -- which include side effects that could lead to a life-threatening outcome, death or hospitalization -- was 10 percent for Alimta patients and 24 percent for docetaxel patients (p= <0.001).
The incidence of grades 3/4 Alanine Transaminase (ALT) -- a laboratory measurement of liver function -- was 1.9 percent in the Alimta arm, a rate that was significantly greater than in the docetaxel arm (p=0.028). According to findings, the incidence of grades 3/4 ALT in the Alimta arm was transient.
Alimta Data in First-Line NSCLC
In addition to its role in the second-line treatment of NSCLC, Alimta is also being investigated as a potential option for the treatment of first-line and earlier stages of NSCLC. Data disseminated on an additional study presented at the ASCO meeting reported on a single cohort Phase II clinical study which evaluated the safety and efficacy of a triplet therapy in which bevacizumab (Avastin®) was added to the combination of Alimta plus carboplatin, a regimen which has been reported upon in published articles.(ii,iii) Preliminary findings of this study suggest that this triplet therapy can be delivered at full doses of each drug with limited toxicity for the first-line treatment of NSCLC.
"Alimta is a very valuable component of the Lilly Oncology franchise," said Richard Gaynor, M.D., vice president, cancer research and global oncology platform leader for Lilly. "We are extremely pleased that data continue to demonstrate the ability of the combination of Alimta and a platinum agent like carboplatin to serve as a reliable chemotherapeutic foundation for the treatment of non-small cell lung cancer. We are confident that Alimta will continue to provide notable benefits for patients with thoracic cancers and have great hopes for its potential in other tumor types."
Alimta is currently being studied in combination with eleven targeted agents in NSCLC, including bevacizumab (Avastin®), erlotinib (Tarceva®), cetuximab (Erbitux®), bortezomib (Velcade®), Matuzumab, as well as enzastaurin, Lilly's own novel investigational compound.
Alimta is an antifolate, which interferes with a crucial process that allows cancer cells to reproduce and spread. Alimta was first approved by the U.S. Food and Drug Administration in 2004 for malignant pleural mesothelioma, a tumor of the linings of the lungs often associated with exposure to asbestos, and also for second-line treatment of NSCLC. In the two years since its first approval for marketing, Alimta has been approved in 71 countries for either NSCLC or mesothelioma, and has become the leader for these indications in most markets. The most common side effects when Alimta is used as monotherapy are disorders of the blood and lymphatic system, gastrointestinal disorders, fatigue, rash and desquamation.
About Non-Small Cell Lung Cancer
The most common type of lung cancer, non-small cell lung cancer (NSCLC) represents 75-80 percent of all lung cancers. NSCLC has five-tier staging, starting at 0 and rising to the severity of stage IV. 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 blood stream.
Alimta was first approved by the US Food and Drug Administration in 2004 for second-line treatment of non-small cell lung cancer (NSCLC), and for malignant pleural mesothelioma.

Delivered via a 10-minute infusion, Alimta is an antifolate, which interferes with a crucial process that allows cancer cells to reproduce and spread.
