INDIANAPOLIS, June 4, 2012 /PRNewswire/ -- Final results from PARAMOUNT, a Phase III study of ALIMTA®(pemetrexed for injection) in the continuation maintenance setting, demonstrated improved overall survival in patients with advanced nonsquamous non-small cell lung cancer (NSCLC) treated with ALIMTA continuation maintenance, according to data announced today by Eli Lilly and Company (NYSE: LLY). PARAMOUNT results will be presented on Monday, June 4, at the 48th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago, Ill.

Representing a paradigm shift in the treatment of lung cancer, "continuation maintenance" treatment is when one of the same medicines used in the first-line treatment setting is continued as maintenance therapy in an ongoing effort to control the cancer. Prior to the use of maintenance treatment, physicians typically treated a patient with four to six cycles of chemotherapy and then waited until the disease returned or worsened before treating it again. In PARAMOUNT, ALIMTA was prescribed in combination with cisplatin induction therapy immediately followed by maintenance ALIMTA and best supportive care.

PARAMOUNT builds upon previous studies evaluating the use of ALIMTA as a first-line therapy with cisplatin[1], as well as ALIMTA as a maintenance therapy[2] (following non-ALIMTA first-line agents) in patients with advanced nonsquamous NSCLC. However, PARAMOUNT is the first study that evaluated both the use of ALIMTA plus cisplatin therapy followed immediately by the use of ALIMTA in the continuation maintenance setting. At ASCO 2011, the primary progression-free survival results of PARAMOUNT were presented and showed that ALIMTA continuation maintenance improved progression-free survival, or the time a patient is alive without their disease worsening.[3]

Final results of this multicenter, double-blind, placebo-controlled trial demonstrated a statistically significant 22 percent reduction in the risk of death (HR=0.78). Patients achieved a median overall survival of 13.9 months from randomization (16.9 months from start of induction) on the ALIMTA continuation maintenance arm compared to 11.0 months from randomization (14.0 months from start of induction) on the placebo arm.

"The ALIMTA PARAMOUNT study is the first to show a survival benefit in continuation maintenance – answering an important question for physicians treating patients with this type of lung cancer," said Allen S. Melemed, M.D., M.B.A., a senior medical director with Lilly Oncology.

A total of 939 patients with advanced nonsquamous NSCLC were enrolled in the study and received ALIMTA (500 mg/m2on day one of a 21-day cycle) in combination with cisplatin (75 mg/m2) induction therapy. Patients whose disease had not progressed during the ALIMTA + cisplatin induction and had a performance status of 0-1 (n=539) were randomized two-to-one to receive ALIMTA maintenance (500 mg/m2 on day one of a 21-day cycle) plus best supportive care (n=359) or placebo plus best supportive care (n=180) until disease progression. Of randomized patients, 44.9% had either a complete response or partial response and 51.9% had a response of stable disease to ALIMTA plus cisplatin induction treatment. All patients received vitamin B12, folic acid and dexamethasone.

Overall, the most serious (grade 3/4) drug-related adverse events (AEs) were higher for those treated with ALIMTA continuation maintenance versus placebo (12.5% vs. 0.6% laboratory and 11.4% vs. 4.4% non-laboratory). The most commonly reported grade 3/4 drug-related AEs observed on the ALIMTA arm versus placebo were anemia (6.4% vs. 0.6%), fatigue (4.7% vs. 1.1%), and neutropenia (5.8% vs. 0%). There was one potentially drug-related death on the ALIMTA arm and two on the placebo arm. Discontinuations due to AEs were 18% with ALIMTA and 7% with placebo.

PARAMOUNT was conducted specifically in patients with advanced nonsquamous NSCLC because past studies have shown that advanced NSCLC patients with a nonsquamous histology (those with the subtypes of adenocarcinoma, large cell carcinoma or "other" histologies) experienced improved efficacy over the relative comparator arm in the trial, when treated with an ALIMTA regimen.[1],[2],[4] Patients with advanced NSCLC with squamous cell histology were not included in the PARAMOUNT study as ALIMTA has not shown to be effective in this patient population relative to the comparators in these previous trials.

About Non-Small Cell Lung Cancer (NSCLC)

Globally, lung cancer is the most common form of cancer and the biggest killer, causing 1.3 million cancer deaths annually.[5] About 85 – 90 percent of all lung cancers are NSCLC.[6] The liver, bones and brain are potential targets if the cancerous cells enter the bloodstream.

NSCLC comprises a group of histologies or tumor types differentiated by cellular structure. Nonsquamous histology includes adenocarcinoma and large cell carcinoma, which account for more than half of all NSCLC diagnoses[7], as well histologies classified as "other."

Important Safety Information

What is the most important information that I should know about ALIMTA?

ALIMTA can suppress bone marrow function, which may cause low blood cell counts.

ALIMTA may not be appropriate for some patients.

If you are allergic to ALIMTA, tell your doctor because you should not receive it.

If you have liver or kidney problems, be sure to tell your doctor. Your dose of ALIMTA may have to be changed, or ALIMTA may not be right for you.

Your doctor will prescribe a medicine called a "corticosteroid" to take for 3 days during each treatment with ALIMTA. Corticosteroids lower your chances for getting skin reactions with ALIMTA.

It is very important to take folic acid and vitamin B12 prior to and during your treatment with ALIMTA to lower your chances of harmful side effects.

You must take folic acid every day for at least 5 days out of the 7 days before your first dose of ALIMTA. You must keep taking folic acid every day during the time you are getting treatment with ALIMTA, and for 21 days after your last treatment.

Your doctor will give you vitamin B12 injections while you are getting treatment with ALIMTA. You will get your first vitamin B12 injection during the week before your first dose of ALIMTA, and then about every 9 weeks during treatment.

You will have regular blood tests before and during your treatment with ALIMTA. Your doctor may adjust your dose of ALIMTA or delay your treatment based on the results of your blood test and on your general condition.

What should I tell my doctor before receiving ALIMTA?

If you think you are pregnant, are planning to become pregnant, or are nursing, please tell your healthcare team. ALIMTA may harm your unborn or nursing baby. Your physician may advise you to use effective contraception (birth control) to prevent pregnancy while you are being treated with ALIMTA.

Tell your doctor if you are taking other medicines, including prescription and nonprescription medicines, vitamins, and herbal supplements. ALIMTA and other medicines may affect each other, causing serious side effects. Especially, tell your doctor if you are taking medicines called "nonsteroidal anti-inflammatory drugs" (NSAIDs) for pain or swelling.

What are the possible side effects of ALIMTA?

Most patients taking ALIMTA will have side effects. Sometimes it is not always possible to tell whether ALIMTA, another medicine, or the cancer itself is causing these side effects.

Call your doctor right away if you have a fever, chills, diarrhea, or mouth sores. These symptoms could mean you have an infection, which may be severe and could lead to death.

The most common side effects of ALIMTA when given alone or in combination with cisplatin are:

Stomach upset, including nausea, vomiting, diarrhea, or constipation. You can obtain medicines to help control some of these symptoms. Call your doctor if you get any of these symptoms.

Low blood cell counts:

Low red blood cells. Low red blood cells may make you feel tired, get tired easily, appear pale, and become short of breath.

Low white blood cells. Low white blood cells may give you a greater chance for infection. If you have a fever (temperature above 100.4°F) or other signs of infection, call your doctor right away.

Low platelets. Low platelets give you a greater chance for bleeding. Your doctor will do blood tests to check your blood counts before and during treatment with ALIMTA.

Tiredness. You may feel tired or weak for a few days after your ALIMTA treatments. If you have severe weakness or tiredness, call your doctor.

Mouth, throat, lip, or food pipe sores (stomatitis, pharyngitis, esophagitis). You may get redness or sores in your mouth, throat, or on your lips, or you may feel pain or difficulty when drinking or swallowing food. These symptoms may happen a few days after ALIMTA treatment. Talk with your doctor if you get any of these symptoms.

Loss of appetite. You may lose your appetite and lose weight during your treatment. Talk to your doctor if this is a problem for you.

Rash. You may get a rash or itching during treatment. These reactions usually appear between treatments with ALIMTA and usually go away before the next treatment. Skin reactions or rashes that include blistering or peeling may be severe and could lead to death. Call your doctor if you have any of these symptoms.

Talk with your doctor, nurse, or pharmacist about any side effect that bothers you or that doesn't go away.

These are not all the side effects of ALIMTA. For more information, ask your doctor, nurse, or pharmacist.

How is ALIMTA given?

ALIMTA is slowly infused (injected) into a vein. The injection or infusion will last about 10 minutes. You will usually receive ALIMTA once every 21 days (3 weeks).

For more information about all of the side effects of ALIMTA, please talk with your healthcare team, see thePatient Prescribing Informationandfull Prescribing Information, or call 1-800-545-5979.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visitwww.fda.gov/medwatch, or call 1-800-FDA-1088.
