Chicago -- June 5, 2017 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the Phase III ALEX study showed Alecensa® (alectinib) significantly reduced the risk of disease worsening or death (progression-free survival, PFS) by more than half (53 percent) compared to crizotinib when given as initial (first-line) treatment for people with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC) (hazard ratio [HR]=0.47, 95 percent CI: 0.34-0.65, p<0.0001). Median PFS reported by the investigators, the primary endpoint of the study, was not yet reached in people who received Alecensa (95 percent CI: 17.7-not reached) versus 11.1 months (95 percent CI: 9.1-13.1 months) in those who received crizotinib. Median PFS assessed by an independent review committee (IRC), a secondary endpoint, was 25.7 months (95 percent CI: 19.9-not reached) for people who received Alecensa versus 10.4 months (95 percent CI: 7.7-14.6 months) for people who received crizotinib (HR=0.50, 95 percent CI: 0.36-0.70, p<0.0001). The safety profile of Alecensa was consistent with that observed in previous studies.
“Alecensa reduced the risk of disease progression by more than half and reduced the risk of cancer spreading to or growing in the brain, which can have devastating effects for patients,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “These results significantly improve upon the standard of care for this disease, extending the average time that people lived without their disease worsening from less than a year to more than two years. We are submitting these data to regulatory authorities around the world.”
The global, randomized Phase III ALEX study also demonstrated that Alecensa reduced the risk of disease progression in the central nervous system (CNS) by 84 percent (HR=0.16, 95 percent CI: 0.10-0.28, p<0.0001). The 12-month cumulative rate of CNS progression for people with or without existing CNS metastases at baseline was 9.4 percent (95 percent CI: 5.4-14.7 percent) for people treated with Alecensa and 41.4 percent (95 percent CI: 33.2-49.4 percent) for people treated with crizotinib.
The official ALEX data presentation at the American Society of Clinical Oncology (ASCO) annual meeting will be on Tuesday, June 6, 2017, at 12:09 – 12:21 p.m. CST (Abstract #9008). The data will be simultaneously published in the New England Journal of Medicine and will be featured in the official ASCO press program on Monday, June 5, 2017, at 8:00 a.m. CST.
Data from the ALEX study will be submitted to global health authorities, including the U.S. Food and Drug Administration (FDA), which in September 2016 granted Alecensa Breakthrough Therapy Designation (BTD) for the treatment of people with advanced ALK-positive NSCLC who have not received prior treatment with an ALK inhibitor.
Alecensa was granted accelerated approval by the FDA in December 2015 for the treatment of people with ALK-positive NSCLC who have progressed on or are intolerant to crizotinib. The ALEX study is part of the company’s commitment in the U.S. to convert the current accelerated approval of Alecensa in people with ALK-positive, metastatic NSCLC who have progressed on or are intolerant to crizotinib to a full approval as an initial treatment.
About the ALEX Study
ALEX (NCT02075840/B028984) is a randomized, multicenter, open-label Phase III study evaluating the efficacy and safety of Alecensa versus crizotinib in treatment-naïve people with ALK-positive NSCLC whose tumors were characterized as ALK-positive by the VENTANA ALK (D5F3) CDx Assay, a companion immunohistochemistry (IHC) test developed by Roche Tissue Diagnostics. People were randomized (1:1) to receive either Alecensa or crizotinib. The primary endpoint of the ALEX study is PFS as assessed by the investigator and secondary endpoints include: IRC-assessed PFS, time to CNS progression, objective response rate (as defined by RECIST criteria), duration of response, overall survival, health-related quality of life and safety. The multicenter study was conducted in 303 people across 161 sites in 31 countries. Results include:
About Lung Cancer
According to the American Cancer Society, it is estimated that more than 222,000 Americans will be diagnosed with lung cancer in 2017, and NSCLC accounts for 85 percent of all lung cancers. It is estimated that approximately 60 percent of lung cancer diagnoses in the United States are made when the disease is in the advanced stages.
Alecensa is a kinase inhibitor approved for the treatment of people with anaplastic lymphoma kinase (ALK)-positive, metastatic non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to crizotinib. This indication is approved under accelerated approval based on tumor response rate and duration of response (DOR). Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
Important Safety Information
Everyone reacts differently to treatment with Alecensa. It’s important to know the most serious and most common side effects with Alecensa.
A doctor may lower the dose or stop treatment with Alecensa if any serious side effects occur. Patients taking Alecensa should contact their doctor right away if they have any of the following side effects.
Alecensa may cause serious side effects, including:
Liver problems (hepatotoxicity). Alecensa may cause liver injury. A doctor will do blood tests at least every 2 weeks for the first 3 months and as needed during treatment with Alecensa. Patients taking Alecensa should tell their doctor right away if they experience any of the following signs and symptoms:
Lung problems. Alecensa may cause severe or life-threatening swelling (inflammation) of the lungs during treatment.
Symptoms may be similar to those symptoms from lung cancer. Patients taking Alecensa should tell their doctor right away if they have any new or worsening symptoms, including:
Slow heartbeat (bradycardia). Alecensa may cause very slow heartbeats that can be severe. A doctor will check a patient’s heart rate and blood pressure during treatment with Alecensa. Patients taking Alecensa should tell their doctor right away if they feel dizzy, lightheaded, or faint during treatment with Alecensa. Patients taking Alecensa should tell their doctor if they take any heart or blood pressure medicines.
Muscle pain, tenderness, and weakness (myalgia). Muscle problems are common with Alecensa and can be severe. A doctor will do blood tests at least every 2 weeks for the first month and as needed during treatment with Alecensa. Patients taking Alecensa should tell their doctor right away if they have any new or worsening signs and symptoms of muscle problems, including unexplained muscle pain or muscle pain that does not go away, tenderness, or weakness.
Before taking Alecensa, patients should tell their doctor about all medical conditions, including if they:
Patients taking Alecensa should tell their doctor about all the medicines they take, including prescription medicines, over-the-counter medicines, vitamins, and herbal supplements.

Patients taking Alecensa may burn more easily and get severe sunburns. Patients taking Alecensa should use sunscreen and lip balm with a SPF 50 or greater to help protect against sunburn.
The most common side effects of Alecensa include:
These are not all of the possible side effects of Alecensa. For more information, patients should ask their doctor or pharmacist. Patients should call their doctor for medical advice about side effects.
