Current state, 2026.

What is live now

The 2026 picture is a five-regulator divergence matrix overlaid with a partially harmonised E6(R3) substrate. The shifts below are operational, not theoretical — they affect dossier preparation today.

/ ICH E6(R3) status

Step 4 reached, implementation rolling.

ICH E6(R3) Step 4 is the current global anchor, but regional implementation status should be verified on FDA, EMA, MHRA, PMDA, CDSCO, Health Canada, ANVISA, and other regulator pages before relying on a local requirement.

/ EU CTR · CTIS

Transition window closed.

All ongoing EU trials under CTR 536/2014 from 31 Jan 2025. Single submission, Reporting MS / Concerned MS dynamics stabilising. Public disclosure (protocols, lay summaries, results) default with limited deferral. Midcap and academic sponsors under-resourced.

/ Five-regulator matrix

Divergence persists.

FDA, EMA/CTR/CTIS, CDSCO, PMDA, ANVISA, MHRA, Health Canada, and TGA all need jurisdiction-specific evidence maps. Timelines and portals should be checked from current official pages before operational planning.

/ Submission timelines

FDA most predictable.

Submission clocks differ by product, phase, dossier quality, ethics pathway, questions received, and country procedure. Use current regulator pages and recent local experience before committing timelines.

/ Decentralised trials

Regulatory option, not experimental.

DCT and hybrid elements are now addressed in multiple regulator frameworks. Remote consent, telemedicine, home nursing, source-data access, and IMP shipment remain jurisdiction- and protocol-specific control questions.

/ Diversity Action Plans

Operational expectation.

FDA Diversity Action Plan expectations should be read against the current FDORA and FDA guidance status. Enrolment goals, rationale, and operational measures need programme-specific feasibility logic.

/ Combination products

MDR Article 117 in force.

FDA 21 CFR 4 + PMOA-led IND or IND+IDE. EU: CTR medicinal portion + MDR Article 117 notified-body opinion for device-integral DDCs. CDSCO recognised but determination less codified. PMDA Combination Office. ANVISA RDC 751 + RDC 945 case-by-case.

/ ANVISA RDC 945

Brazil is a jurisdiction to watch.

Brazil's 2024 clinical-research framework and ANVISA implementation changes make Brazil a jurisdiction to watch. Specific timelines, official submission systems, CONEP/CEP interaction, and DCT recognition should be checked against current ANVISA and official Brazilian sources before relying on them operationally.

/ India ICH trajectory

India ICH trajectory.

India's NDCT 2019 framework, ICH Observer status, pharmacovigilance growth, and regulatory-capacity initiatives make India important to track. Full ICH Regulatory Member status should be described only when formally confirmed by ICH and CDSCO sources.

/ Ethics review divergence

Single-IRB now common in US.

FDA local and central IRB pathways exist. EMA Part II remains national under CTR. India, Japan, and Brazil retain specific ethics-committee and local-review structures. Teams should verify current local registration, renewal, and submission requirements before site activation.

/ Not yet regulated

Frontier remains open.

Synthetic control arms in pivotals (case-by-case). AI/ML adaptive designs (ICH E20 traditional framework, AI-specific limited). In-silico trial evidence (mechanistic/device niche). Continuous submission models (pilot). Genomic-stratified ultra-rare (immature).

/ Cross-border data flow

Friction, not convergence.

GDPR (EU), DPDP (India), LGPD (Brazil), HIPAA (US). DCT direct-to-participant IMP and telemedicine intersect three or four regimes per trial. Source-data verification across jurisdictions remains an inspection question.

/ WHO GCTP 2024

Design-agnostic quality frame.

WHO Good Clinical Trials Practice 2024 frames quality without prescribing design. Useful for LMIC regulators bootstrapping frameworks. Listed Authority pathway parallel-tracks regulator maturity.
