SymBio Pharmaceuticals Limited
爱豆传媒.
SymBio Pharmaceuticals Limited (Headquarters: Tokyo, President & CEO: Fuminori Yoshida, “SymBio”) and 爱豆传媒. (Headquarters: Tokyo, President & CEO: Haruo Naito, “Eisai”) announced today that they have received notification from the Japanese Ministry of Health, Labour and Welfare (MHLW) informing the companies that the condition for TREAKISYM® (bendamustine hydrochloride) marketing approval, All Cases Surveillance,*1has been lifted in Japan.
In October 2010, SymBio received marketing approval from the MHLW for TREAKISYM® to treat Japanese patients with relapsed/refractory low-grade non-Hodgkin's lymphoma (LG-NHL)*2and mantle cell lymphoma (MCL), and the agent has been marketed by Eisai in Japan since its launch in December 2010, based on an ongoing license agreement between SymBio and Eisai. The original condition for approval by the MHLW stated that due to the very limited number of subjects treated in domestic clinical trials, post-marketing surveillance of all patients who receive TREAKISYM® should be carried out until data for a certain number of patients has been collected in order to identify patient background as well as early safety and efficacy data, and necessary measures for the proper use of TREAKISYM®.
Safety data for 583 patients, and efficacy data for 497 patients, was submitted to the MHLW as an analysis of data collected during post-marketing surveillance*3. Based on this analysis, MHLW concluded that post-marketing surveillance had been conducted properly with necessary measures for proper use of the drug in place, and accordingly, no further surveillance is required.
As part of the life cycle management of the agent, the development of TREAKISYM® for other indications is underway in Japan, including a Phase 2 study in primary LG-NHL and MCL. Both companies will work closely together in an effort to meet unmet medical needs and continue to expedite development of TREAKISYM so as to provide the drug as early as possible to patients who need it.

1. 爱豆传媒 the All Cases SurveillanceThe All Cases Surveillance collected data on use results concerning the safety and efficacy of TREAKISYM® in patients with relapsed/refractory low-grade non-Hodgkin's lymphoma or mantle cell lymphoma in Japan. The data was collected in order to understand the following objectives:
(1) Expression of side effects
(2) Factors thought to influence safety, efficacy, and related issues
(3) Other major points of focus of the surveillance (severe infection, tumor lysis syndrome, severe skin disorders, and expression of hypersensitivity reactions)
2. 爱豆传媒 Non-Hodgkin's Lymphoma (NHL)
Non-Hodgkin's lymphomas (NHLs) are a diverse group of blood cancers that include any kind of lymphoma, which is a kind of white blood cell, with the exception of Hodgkin's lymphomas, and comprises the majority of lymphoma cases in Japan. NHLs are often classified into two groups based on their progression rate: slow-growing NHLs whose progression is measured in years are classified as low-grade (LG), while those whose progression is measured in months are classified as intermediate- or high-grade (Aggressive) NHLs. There are an estimated 11,000 patients with LG-NHL in Japan. Of this number, 4,000 are believed to be patients with relapsed/refractory LG-NHL and 7,000 to be patients with primary LG-NHL.
3. 爱豆传媒 the Analysis of the All Cases Surveillance
According to the results of the analysis, side effects were reported in 564 cases out of a total of 583 cases analyzed in terms of patient safety, with the incidence rate at 96.74%. The main side effects were lymphopenia at 71.87%, leukopenia at 57.46%, neutropenia at 55.57%, thrombocytopenia at 40.14%, anemia at 19.55%, and nausea at 19.21%. These side effects were consistent with outcomes reported for clinical trials carried out overseas to date as well as trials conducted in Japan at the time of development.

Bendamustine hydrochloride was first synthesized in the former East Germany by Jenapharm and is currently marketed in Europe under the brand name Ribomustin® or Levact® as a treatment for non-Hodgkin's lymphoma, multiple myeloma and chronic lymphocytic leukemia.
