TAK-003 Dengue Vaccine Description
Takeda's TAK-003 is an investigational live-attenuated tetravalent dengue vaccine, preventing dengue fever caused by any of the four serotypes of the dengue virus that causes dengue fever or Severe Dengue. TAK-003 (TDV) is based on a live-attenuated dengue serotype two virus, which provides the genetic "backbone" for all four dengue serotypes.
Takeda's current clinical development program consists of five Phase 3 trials. Phase 1 and 2 data in children and adolescents showed that TAK-003 induced immune responses against all four dengue serotypes in seropositive and seronegative participants. The vaccine was found to be generally safe and well-tolerated.
In a November 2019 study, Takeda's dengue vaccine candidate demonstrated protection against virologically confirmed dengue, the trial's primary endpoint, in children ages 4 to 16 years. The vaccine efficacy (VE) was 80.2% in the 12 months after the 2nd vaccine dose, administered 3-months after the 1st dose.
The Lancet published an article on March 17, 2020, safety and immunogenicity of a tetravalent dengue vaccine in children aged 2–17 years: a randomized, placebo-controlled, phase 2 trial, which concluded saying 'TAK-003 elicited antibody responses against all four serotypes, which persisted to 48 months post-vaccination, regardless of baseline serostatus.'
And recently, on July 13, 2020, the Long-term safety and immunogenicity of a tetravalent dengue vaccine candidate in children and adults: a randomized, placebo-controlled, phase 2 study, found at Month 36, seropositivity rates were 97.3%, 98.7%, 88.0% and 56.0% for DENV-1, -2, -3 and -4, respectively. Seropositivity rates varied significantly for DENV-4 according to serostatus at baseline (89.5% in seropositive versus 21.6% in seronegative). No vaccine-related SAEs were reported.
On March 25, 2021, the Company announced Takeda is participating in the EMA's first-ever parallel assessment of a medicinal product for use in the European Union and through the EU-M4all (previously Article 58) procedure for countries outside of the EU. Derek Wallace, VP, Dengue Global Program Leader at Takeda, stated in a press release, "Submission of regulatory filings for our dengue vaccine candidate, TAK-003, marks an important development for people who are living in or traveling to communities burdened by the threat of dengue." Takeda intends to submit regulatory filings in Argentina, Brazil, Colombia, Indonesia, Malaysia, Mexico, Singapore, Sri Lanka, and Thailand during 2021.
On May 20, 2021, an audio review of Three Years Efficacy of Takeda's Tetravalent Dengue Vaccine Candidate was published.
The journal Clinical Infectious Disease published an ACCEPTED MANUSCRIPT on October 4, 2021: Three years efficacy and safety of Takeda's dengue vaccine candidate (TAK-003). This study concluded by stating, 'TAK-003 was efficacious against symptomatic dengue over three years. Efficacy declined over time but remained robust against hospitalized dengue.'

TAK-003 Dengue Vaccine Indication
The TAK-003 vaccine candidate is indicated to prevent the Dengue virus caused by any of the four Dengue serotypes. Dengue is the fastest spreading mosquito-borne viral disease and is one of the World Health Organization's top 10 global health threats in 2019.
On March 17, 2020, The Lancet published two studies that concluded 'TAK-003 was well tolerated and efficacious against symptomatic dengue in children regardless of serostatus before immunization in a phase three study. However, vaccine efficacy varied by serotype, warranting continued follow-up to assess longer-term vaccine performance.' And a phase two study reported 'TAK-003 elicited antibody responses against all four serotypes, which persisted to 48 months post-vaccination, regardless of baseline serostatus.'
On May 22, 2021, Takeda confirmed TAK-003 prevented 83.6% of Hospitalizations and 62.0% of Dengue Illness Overall, With No Identified Important Safety Risks Through Three Years Following Vaccination in Ongoing Pivotal Phase 3 TIDES Trial.
On June 10, 2021, the NEJM reported, 'In 2019, a total of 413 dengue cases were probably imported to Florida, including 14 cases of severe dengue (3.4%), predominantly in the Miami area. In addition, most travel-associated patients reported recent travel to Cuba and were infected with dengue virus serotype 2 (DENV-2).
TAK-003 Dengue Vaccine Dosage
In clinical studies, TAK-003 was given as a single DV 0.5 mL subcutaneous injection on Day 1 and Day 90. The onset of protection was seen after the 1st dose, with 81% VE between the 1st and 2nd doses.
TAK-003 Dengue Vaccine Side Effects
The ongoing phase 3 study demonstrated rates of serious adverse events were 2.9% in the TAK-003 group and 3.5% in the placebo group during the ongoing long-term follow-up (i.e., the second half of the three years following vaccination), but none were related. Therefore, no important safety risks were identified.
