Takeda Test Dengue Vaccine Hub Phase 3 Efficacy Test meets primary endpoint – Business Wire China

– The study found that the candidate vaccine was well tolerated and that no significant safety issues were identified in the analysis so far –

Cambridge, MA and Osaka, Japan – (BUSINESS WIRE) – Takeda Pharmaceutical Co., Ltd.[TSE:4502 / NYSE:TAK]("Wuta") today announced that its key phase 3 trial of a candidate for dengue vaccination has reached its primary endpoint of efficacy. A first analysis of tetanus dengue (TIDES) activity showed that active attenuated tetravalent dengue vaccine (TAK-003) was effective in preventing dengue fever caused by one of four dengue virus serotypes. Although the review of the entire dataset is still ongoing, TAK-003 is well tolerated and no major safety concerns have been observed yet. The TIDES test runs and other results are expected in connection with the results of the other three phases in the second half of this year.from

MUDr. Rajeev Venkayya, chairman of the Takeda Global Vaccine Business Unit, said: "We are encouraged by the execution of our dengue vaccine candidate in this study, helping us to help the world make the next step in the dengue burden." Yes, the information will be published as soon as possible in professional journals At the same time, we promote clinical development, commercial production and stakeholder consultation to support the possibility that the vaccine will be sold globally in the future. "

The TIDES study is the largest intervention clinical trial ever conducted by Takeda, with over 20,000 healthy children and adolescents living in areas prone to dengue aged 4 to 16 years. This study was designed to evaluate the efficacy, safety and immunogenicity of two doses of TAK-003 in exposed and unexposed dengue individuals.from



TAK-003 has not yet been approved in any part of the world. In addition to dengue, Takeda develops vaccines that respond to other high-priority infectious diseases, including Zika, Norovirus and Polio.

O3PeriodTIDES (DEN-301)Test

The double-blind, randomized, placebo-controlled TIDES trial from Phase 3 evaluated the safety and efficacy of two doses of TAK-003 in the prevention of laboratory-confirmed symptomatic dengue due to any severity in children and adolescents and in all four serotypes of Dengue Sexfrom


. Participants were randomized to subcutaneous injection of 0.5 ml of TAK-003 or placebo on days 1 and 90.from


. The study is divided into three parts. The current analysis is part 1, which evaluates vaccine efficacy (VE) and safety 15 months after the first injection. Part 2 continued for 6 months in order to achieve a secondary endpoint assessment of VE endpoints based on serotype, baseline serum and severity. Part 3 has been monitored for 3 years in order to assess VE and long-term safetyfrom


. The information set out in Parts 1 and 2 is the basis for the submission of the review.

Attempts were made in areas with daily illness including Latin America (Brazil, Colombia, Panama, Dominican Republic and Nicaragua) and Asia (Philippines, Thailand and Sri Lanka) where dengue prevention and serious dengue fever was not a major cause of serious illness and death in childrenfrom


. Initial blood samples were taken from all study participants in order to assess safety and efficacy based on serum status. Takeda and the independent expert monitoring committee actively and continuously monitor security.


The four-fold Takeda vaccine for dengue fever (TAK-003) is based on the active attenuated dengue serotype virus type 2, which provides the skeleton gene of all four vaccine viruses.from


. Phase 1 and Phase 2 data from children and adolescents showed that TAK-003 induced an immune response against all four dengue serotypes in seropositive and seronegative subjects, and the vaccine was generally safe and well tolerated.from



About the dengue fever

. Lifetime resistance to this serotype can be achieved by serotyping and recovery. Exposure to any of the other three serotypes may lead to an increased risk of severe dengue fever.from



The outbreak of dengue fever occurs in tropical and subtropical areas and has recently exploded in the United States and parts of Europe.from


. About half of the world's people live under the threat of dengue and it is estimated that 400 million people will be infected worldwide and 20,000 people die each year.from


. Dengue virus can infect people of all ages and is the main cause of serious illness in children in Latin America and parts of Asia.from
