  TearClear Corp. is a clinical-stage ophthalmic pharmaceutical company founded in 2015 that
  develops a preservative-removing drug delivery platform: a chemical filter built into a
  conventional multi-dose eye-drop bottle that captures benzalkonium chloride (BAK) at the
  point of instillation, so the medication stays preserved in the bottle but reaches the
  ocular surface preservative-free. Its lead candidate TC-002 (latanoprost ophthalmic
  solution 0.005%) met the primary and all secondary endpoints in the CLEAR Phase 3 pivotal
  glaucoma trial, with TC-001 (timolol), TC-003 (brimonidine/timolol) and TC-004
  (brimonidine) behind it. TearClear ships drug products and delivery hardware, not
  software: it operates no developer program and publishes no API, SDK or machine-readable
  contract, and its own corporate domain no longer resolves to a served website.

x-website-note: >-
  No `Website` pointer is wired. The company's registered domain, https://tearclear.com,
  returned HTTP 403 on 2026-08-29 over both HTTP and HTTPS with a browser User-Agent, under a
  TLS certificate for gcam1074.siteground.biz and an `x-default-vhost: 1` response header —
  the domain is no longer provisioned as a virtual host on the SiteGround server it points
  at, and the Internet Archive holds no successful capture after 2024-07-24. The previous
  `Website` pointer on this profile was https://www.hiive.com/securities/tearclear-stock, a
  secondary-market trading venue listing rather than the company's own web presence; it has
  been retyped so its live 200 no longer stands in for a website the company does not serve.

  detail: >-
    TearClear is a clinical-stage ophthalmic pharmaceutical company whose product is a
    BAK-removing eye-drop bottle filter and the latanoprost/timolol/brimonidine drugs
    dispensed through it, so there is no software product to expose an API on; separately,
    its own domain tearclear.com now answers 403 from an unprovisioned SiteGround default
    vhost, and no api./developer./docs. subdomain resolves at all.
