SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that Alecensa® (alectinib), an oral anaplastic lymphoma kinase (ALK) inhibitor, reduced the risk of disease worsening or death (progression-free survival, PFS) by 66 percent compared to crizotinib in Japanese people with advanced or recurrent, ALK-positive non-small cell lung cancer (NSCLC) (hazard ratio [HR]=0.34, 99 percent CI: 0.17-0.70, p<0.0001). Median PFS was not reached in people who received Alecensa (95 percent CI: 20.3 months-not reached) versus 10.2 months median PFS (95 percent CI: 8.2-12.0) in people who received crizotinib. The results were from a pre-specified interim analysis from the Phase III J-ALEX study in people who had not received prior treatment with an ALK inhibitor. There were fewer adverse events (AEs) in the Alecensa arm versus the crizotinib arm. Alecensa demonstrated a safety profile consistent with that observed in previous studies with no new or unexpected AEs.
“This is the first investigational study to show Alecensa helped people live longer without their disease getting worse compared to crizotinib,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We believe these efficacy and safety results represent a clinically meaningful advancement for people with ALK-positive lung cancer, and we plan to discuss these data with health authorities, including the FDA.”
The official data presentation at the American Society of Clinical Oncology (ASCO) annual meeting will be on Monday, June 6, from 12:09 - 12:21 P.M. CDT (Abstract #9008).
Alecensa was granted accelerated approval by the U.S. Food and Drug Administration (FDA) in December 2015 for the treatment of people with ALK-positive NSCLC who have progressed on or are intolerant to crizotinib. ALEX, a global, randomized Phase III study, is ongoing, comparing Alecensa to crizotinib as an initial (first-line) treatment for people with advanced NSCLC whose tumors were characterized as ALK-positive by a companion VENTANA ALK (D5F3) CDx Assay immunohistochemistry (IHC) test developed by Roche Tissue Diagnostics. This study is part of the company’s commitment to convert the current accelerated approval in people with ALK-positive, metastatic NSCLC who have progressed on or are intolerant to crizotinib to a full approval as an initial treatment.
The J-ALEX study conducted by Chugai is an open-label, randomized Phase III study that compared the efficacy and safety of Alecensa to crizotinib in Japanese people. The J-ALEX study enrolled 207 people with ALK-positive, advanced or recurrent NSCLC who had not been previously treated with an ALK inhibitor. People were randomized to the Alecensa group or the crizotinib group in a one-to-one ratio. Results include:
- Alecensa reduced the risk of disease worsening or death (PFS) by 66 percent compared to crizotinib (HR=0.34, 99 percent CI: 0.17-0.70, p<0.0001).
- Median PFS was not reached in the Alecensa arm (95 percent CI: 20.3 months-not estimated) versus 10.2 months in the crizotinib arm (95 percent CI: 8.2-12.0).
- Grade 3-4 AEs occurred with greater frequency in the crizotinib arm compared to the Alecensa arm (51 percent vs. 27 percent).
- The most common AE occurring with > 30 percent frequency with Alecensa was constipation (36 percent). The most common AEs for crizotinib were nausea (74 percent), diarrhea (73 percent), vomiting (59 percent), visual disturbance (55 percent), alteration in taste (dysgeusia; 52 percent), constipation (46 percent), and an elevation in liver enzymes called alanine transaminase (ALT, 32 percent) and aspartate transaminase (AST, 31 percent).
About Lung Cancer
According to the American Cancer Society, it is estimated that more than 224,000 Americans will be diagnosed with lung cancer in 2016, 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 2 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:
- Feeling tired
- Feeling less hungry than usual
- Yellowing of the skin or whites of the eyes
- Dark urine
- Itchy skin
- Nausea or vomiting
- Pain on the right side of stomach area
- Bleeding or bruising more easily than normal
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:
- Trouble breathing
- Shortness of breath
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.
