TOKYO, February 1, 2018 -- Roche Diagnostics K.K. (Main Office: Minato-ku, Tokyo. President & CEO: Makoto Ogasawara) announced today that it has filed an application for partial changes for an in vitro diagnostic “VENTANA OptiView ALK (D5F3)” to identify ALK-positive non-small cell lung cancer (NSCLC) patients. The company aims to receive regulatory approval of the drug as a companion diagnostic for the treatment with ALK inhibitor “Alecensa” launched by Chugai Pharmaceutical Co., Ltd. (Main Office: Chuo-ku, Tokyo. Chairman & CEO: Osamu Nagayama).
“VENTANA OptiView ALK (D5F3)” is an ALK fusion protein kit launched by Roche Diagnostics. It is currently indicated as an aid to identify NSCLC patients eligible for the treatment with crizotinib and ceritinib. By using an automated immunohistochemistry (IHC) staining instrument from the “VENTANA BENCHMARK” series, it enables efficient and timely results, as an optical microscope can be used for the interpretation of the test, and there is no need for complex procedures.
If an additional indication for the ALK inhibitor "Alecensa" is approved, “VENTANA OptiView ALK (D5F3)” will be the companion diagnostic for all ALK inhibitors currently available in Japan. Roche Diagnostics is confident that the expanded indication of this diagnostic will further contribute to the early diagnosis and early treatment for patients eligible for these treatments.
Alecensa is a highly selective oral ALK inhibitor originated by Chugai. The detection of ALK is mandatory for the treatment with Alecensa, and with the label expansion of “VENTANA OptiView ALK (D5F3)” for Alecensa, it is expected to contribute to the timely and appropriate diagnosis of a positive result for the ALK fusion gene.
Roche Diagnostics and Chugai are members of the Roche Group, a pioneer in personalized healthcare, will continue to dedicate ourselves to provide the right treatment for the right group of patients.
About VENTANA OptiView ALK (D5F3)
VENTANA OptiView ALK (D5F3) is an in vitro diagnostic approved in combination with the primary antibody (clone D5F3), a rabbit monoclonal antibody, the highly sensitive detection kit “VENTANA OptiView DAB Universal Kit”, and the “VENTANA OptiView Amplification Kit” that conducts tyramide amplification, making it possible to conduct testing in pathology labs in a more efficient and timely manner. VENTANA OptiView ALK (D5F3) is the only companion diagnostic approved using the IHC method alone to identify patients eligible for treatments with ALK inhibitors.
It has been reported that approximately five percent of patients with NSCLC express a chromosomal rearrangement which leads to fusion of the ALK gene with another gene1). ALK kinase signalling is constantly active in cells with such fusion genes, resulting in uncontrolled growth of tumour cells and transforming the cells into tumour cells2, 3). Alecensa exerts its anti-tumour effect by selectively inhibiting ALK kinase activity to inhibit tumour cell proliferation and induce cell death4).
Outside of Japan, Alecensa is currently approved in the United States, Europe, Kuwait, Israel, Hong Kong, Canada, South Korea, Switzerland, India, Australia, Singapore, Taiwan, Thailand, Liechtenstein, Argentina, United Arab Emirates, Saudi Arabia and Turkey for the treatment of people with metastatic (advanced) ALK-positive NSCLC whose disease has worsened after, or who could not tolerate treatment with, crizotinib and in the US, EU and Turkey for the treatment of first line therapy on ALK-positive metastatic NSCLC.
In Japan, Alecensa is available to patients with “ALK fusion gene positive unresectable, recurrent/advanced NSCLC” and is marketed as "Alecensa® capsule 150mg" by Chugai under the name.
