1 of 2 active trials have accepted investigational programme links. Trial context does not establish ownership or complete drug coverage.

1 selected programmes · accepted investigational links cover 1 of 2 active trials · brand names checked where available.

Accepted links do not establish complete intervention mapping or ownership. Programme populations overlap.

Up to six canonical assets identified through accepted investigational links in active trials. Counts describe this trial context and do not establish ownership or a complete corporate drug portfolio. Opening a record requires sign-in and does not start tracking.

    Sources, scope and methodology

    ClinicalTrials.gov lead-sponsor scope

    Exact Verona operating-company subset covers 18 distinct NCT records attributed through the canonical sponsor map. Included canonical entities: Merck & Co. Phrases retrieve candidates only, then verbatim lead-sponsor attribution determines inclusion. Only the exact supported Verona operating identity with independent Merck attribution is included. Other Verona name variants remain unestablished. This subset also appears on the Merck page.

    ClinicalTrials.gov

    Attribution coverage

    18 distinct registry candidates produced 18 accepted studies. 0 mapped to other owners, 0 lacked a canonical mapping and 0 fell outside an operating subset. Accepted mappings include 0 unverified, 0 identity-only and 0 device-tagged trial memberships. Mapping flags describe evidence quality, not a separate ownership authority.

    Indexed enrichment

    18 scoped records have indexed enrichment and 0 do not. Missing enrichment does not remove a trial from cohort counts.

    Scope observation

    The successful attribution check completed at 2026-11-01T00:33:41.451Z. This is a dated canonical-attribution snapshot. Static pages normally regenerate after 24 hours, but cached HTML can outlive that interval when regeneration fails. Map changes affect the next successful regeneration. This timestamp is separate from individual registry-update dates. Snapshot e7fc949fb40100007c73628d45d54c96c04faa1d67956ec56f84710b3d339e8e.

    Active means recruiting, not yet recruiting, active not recruiting or enrolling by invitation. Recruiting counts recruiting only. Trial counts describe lead sponsorship under the published canonical-attribution policy. Identified programmes and therapeutic groups depend on available enrichment. Drug, device and other clinical studies may be included. This is the mapped company scope, not an exhaustive corporate trial census.

    Dated canonical-attribution snapshot: 18 mapped lead-sponsored clinical studies across all statuses. 18 have indexed enrichment. Drug, device and other studies may be represented. Sponsor tags do not classify trial interventions. This is the mapped company scope, not an exhaustive corporate trial census. Recorded changes may reflect observation or archive ingestion rather than a new registry amendment.
