MCP evidence snapshot: 21 July 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.

Why NCT07712926 is a hot trial to watch

Dengue is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07712926 is notable because it evaluates Tetravalent dengue virus vaccine(Instituto Butantan) in a Phase 3 design sponsored by Instituto Butantan. The main development question is whether the protocol can translate its rationale into a clinically interpretable and operationally credible readout.

Trial landscape snapshot

Protocol design and endpoint interpretation

This randomized, double-blind, three parallel-group, multicenter, phase 3b trial evaluates the safety and immunogenicity of Butantan-DV. The study compares two primary immunization regimens (Butantan-DV/Butantan-DV vs. Butantan-DV/Placebo) across both the 2-11 and 12-17 age cohorts. It also evaluates the manufacturing facility transition for the Butantan-DV dengue vaccine, by comparing the open-label arm WuXi Biologics (Butantan-DV group) to both double-blinded Butantan-DV/Butantan-DV and Butantan-DV/Placebo arms, in adolescents aged 12 to 17.

Allocation is Randomized, masking is Double, and the intervention model is Parallel Assignment. Planned enrollment of 1765 participants across Not reported in the indexed record shapes statistical precision, execution risk and external validity. Interpretation should account for baseline risk, prior therapy, assessment schedule, missing-data handling and clinical relevance—not only statistical significance.

• Immunogenicity - 1 (Group Butantan-DV (IB) + Butantan-DV (IB) on Day 302 and Group Butantan-DV (IB) + Placebo (IB) on Day 29 post vaccination.) — Geometric Mean Fold-Rise ratio of neutralizing antibodies measured by PRNT50 against the four dengue virus serotypes (DENV-1, DENV-2, DENV-3, and DENV-4) in participants in the Butantan-DV (IB) + Butantan-DV (IB) group, compared to participants in the Butantan-DV (IB) + Placebo (IB) group, in children aged 2 to 11 years.
• Immunogenicity - 2 (Group Butantan-DV (IB) + Butantan-DV (IB) on Day 302 and Group Butantan-DV (IB) + Placebo (IB) on Day 29 post vaccination.) — Geometric Mean Fold-Rise ratio of neutralizing antibodies measured by PRNT50 against the four dengue virus serotypes (DENV-1, DENV-2, DENV-3, and DENV-4) in participants of the Butantan-DV (IB) + Butantan-DV (IB) group at Day 302, compared to participants of the Butantan-DV (IB) + Placebo (IB) group at Day 29, in adolescents aged 12 to 17 years.
• Immunogenicity - 3 (Day 29 post vaccination.) — Geometric Mean Fold-Rise ratio of neutralizing antibodies measured by PRNT50 against the four dengue virus serotypes (DENV-1, DENV-2, DENV-3, and DENV-4) in participants of the Butantan-DV (WuXi) Group compared to participants of the other two Butantan-DV (IB) groups, in adolescents aged 12 to 17 years.

Readout outlook and evidence gap

The current protocol points to 2028-02-28 as the best available readout proxy. Because this is an active or newly posted study, a trial-specific result citation is not included until a normalized clinical-trial-result record becomes available. That gap is itself operationally important: teams should monitor first result indexing, conference abstracts, protocol amendments and changes to the primary-completion date.

Asset and sponsor context

Trial-sourced asset: Tetravalent dengue virus vaccine(Instituto Butantan). The Drug & Asset MCP enrichment step is designed to add normalized targets, modality and global development status when an exact asset match is available.

Trial-sourced sponsor: Instituto Butantan. Company & Deal Intelligence MCP is the companion workflow for resolving organization identity, corporate profile and partnering context.

The sponsor profile matters because scientific rationale alone does not determine development value. Manufacturing readiness, portfolio fit, geographic reach, partnering capacity and the ability to fund confirmatory development can determine whether a positive signal becomes a competitive asset.

White space around this program

• Sharper patient selection: prospective biomarker or phenotype definitions that identify who is most likely to benefit.
• Clinically interpretable endpoints: outcomes connecting activity with function, symptoms, survival or treatment burden.
• Comparator relevance: evidence against the most decision-relevant contemporary standard of care.
• Broader external validity: evidence across additional geographies, demographic groups and real-world settings.
• Operational differentiation: a development path that closes the readout gap without sacrificing safety or durability.

What to monitor next

Monitor recruitment, enrollment changes, protocol amendments, endpoint hierarchy, primary-completion timing, first result indexing, asset ownership and sponsor partnerships. A change in endpoint, population or ownership can alter the probability of success before a headline data release.

Bottom line

NCT07712926 provides a focused lens on Dengue development. Its value will be determined by whether Tetravalent dengue virus vaccine(Instituto Butantan) can convert the current Phase 3 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
