TOKYO, September 4, 2019 -- Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) announced today the launch of Rozlytrek® capsules 100 mg and 200 mg (generic name: entrectinib) (hereafter, Rozlytrek), an anticancer agent/tyrosine kinase inhibitor, for the treatment of NTRK fusion-positive advanced or recurrent solid tumors.

"We are very pleased that we can now provide Rozlytrek to patients as the first drug for the treatment of NTRK fusion-positive solid tumors in Japan,” said Dr. Osamu Okuda, Chugai’s Executive Vice President, Co-Head of Project & Lifecycle Management Unit. “Rozlytrek is a drug that embodies advanced personalized healthcare as it has been approved to treat solid tumors with rare gene fusions regardless of their site of origin. We will continue to take every measures to provide proper information to ensure the safe use of Rozlytrek."

Rozlytrek is a drug that will realize the advance in personalized healthcare, which is one of the goals set by Chugai. After receiving Sakigake designation from the Ministry of Health, Labour and Welfare (MHLW) for NTRK fusion-positive advanced/recurrent solid tumors with extremely rare gene mutation, Chugai obtained the world’s first regulatory approval for Rozlytrek in Japan on June 18, 2019. Rozlytrek is the first drug approved in Japan for the treatment of NTRK fusion-positive solid tumors as a tumor agnostic treatment in both adult and pediatric patients. In other countries, Rozlytrek has been granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) and was approved for the treatment of NTRK fusion-positive solid tumors on August 15, 2019. The European Medicines Agency (EMA) has designated Rozlytrek as PRIority MEdicines (PRIME).

For Biomarker testing of NTRK gene fusions, Chugai obtained approval of FoundationOne® CDx Cancer Genomic Profile as a companion diagnostic for Rozlytrek by the MHLW on June 26, 2019.

As a leading company in the field of oncology, Chugai will regard Rozlytrek as the drug to realize advanced personalized healthcare in oncology and contribute to patients and healthcare professionals through the promotion of its appropriate use.
