South San Francisco, CA -- December 11, 2015 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) granted accelerated approval to Alecensa® (alectinib) 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. In the pivotal studies, Alecensa shrank tumors in up to 44 percent of people with ALK-positive NSCLC who progressed on crizotinib (objective response rate [ORR] of 38 percent [95 percent CI 28-49] and 44 percent [95 percent CI 36-53]). In a subset of people with tumors that spread to the brain or other parts of the central nervous system (CNS), Alecensa shrank CNS tumors in about 60 percent of people (CNS ORR of 61 percent [95 percent CI 46-74]).
"Alecensa is now approved as a new option for people with ALK-positive NSCLC who progress on or are intolerant to crizotinib," said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “Sixty percent of people enrolled in our studies had tumors that had spread to their central nervous systems, and Alecensa shrank tumors in many people in a subset of patients with CNS disease."
Possible serious side effects with Alecensa include liver problems, lung problems, slow heartbeat, muscle pain, tenderness and weakness. The most common side effects of Alecensa include tiredness, constipation and swelling in the hands, feet, ankles and eyelids.
The FDA’s Accelerated Approval Program allows conditional approval of a medicine that fills an unmet medical need for a serious condition based on early evidence suggesting clinical benefit. The indication for Alecensa 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.
Alecensa will be available to people in the United States within two weeks. For those who qualify, Genentech plans to offer patient assistance programs for people taking Alecensa through Genentech Access Solutions. Doctors can contact Genentech Access Solutions at (888) 249-4918. More information is also available at http://www.Genentech-Access.com.
In addition, Alecensa is being studied for use as an initial (first-line) treatment for people with advanced ALK-positive NSCLC. ALEX is a global, randomized Phase III study comparing Alecensa to crizotinib as an initial 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 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.
About NP28761 (Study 1) and NP28673 (Study 2)
Study 1 is a Phase II North American, single-arm, open-label, multicenter trial evaluating the safety and efficacy of Alecensa (600 mg orally twice daily) in 87 people with ALK-positive NSCLC whose disease progressed on crizotinib. Study 2 is a Phase I/II global, single-arm, open-label, multicenter trial evaluating the safety and efficacy of Alecensa (600 mg orally twice daily) in 138 people with ALK-positive NSCLC whose disease progressed on crizotinib. People in the Phase II studies received 600 mg of Alecensa orally twice daily. In both trials, the primary endpoint was ORR according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1), as evaluated by an Independent Review Committee (IRC). Secondary endpoints included DOR and efficacy against disease that had spread to the CNS (CNS ORR and CNS DOR). A summary of the efficacy and safety data from both studies that support this approval is included below.

*18 patients in Study 1 and 16 patients in Study 2 did not have measurable disease at baseline as per IRC assessment and were classified as non-responders in the IRC analysis.
aOf 51 people in the subgroup, 35 (69 percent) had received prior brain radiation, including 25 (49 percent) who completed radiation treatment at least 6 months before starting treatment with Alecensa.
The most common Grade 3 or higher adverse events in the pooled analysis of both studies were an increase in muscle enzymes (creatine phosphokinase; 4.6 percent), shortness of breath (dyspnea; 3.6 percent), increased liver enzymes (aspartate transaminase; 3.6 percent, and alanine transaminase; 4.8 percent), evidence of liver dysfunction (hyperbilirubinemia; 2.4 percent), increased blood glucose (hyperglycemia; 2 percent), decreased levels of minerals (hypokalemia; 4 percent, hypophosphatemia; 2.8 percent, and hyponatremia; 2 percent), decreased red blood cells (anemia; 2 percent) and decreased white blood cells (lymphopenia; 4.6 percent).
About Lung Cancer
According to the American Cancer Society, it is estimated that more than 221,000 Americans will be diagnosed with lung cancer in 2015, 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. Approximately 5 percent of people with NSCLC in the United States are ALK-positive. ALK-positive NSCLC is often found in younger people who have a light or non-smoking history.
