description: 'AusperBio — AusperBio Therapeutics, Inc. in the United States and Ausper Biopharma Co., Ltd. (杭州浩博医药有限公司) in
  Hangzhou, China — is a clinical-stage biopharmaceutical company founded in 2019 that develops oligonucleotide and targeted
  delivery technologies, with an initial focus on achieving a functional cure for chronic hepatitis B infection. Its proprietary
  Med-Oligo antisense oligonucleotide (ASO) platform pairs novel ASO design and optimization with targeted delivery conjugation
  chemistry, and its Au-HALO hepatocyte-targeting delivery technology extends the same modular approach to siRNA. The lead
  candidate AHB-137 is an unconjugated ASO that completed enrollment in two Phase II trials and received China CDE clearance
  to enter Phase III; a second clinical candidate, AHB-171, is a hepatocyte-targeted siRNA. The company has raised more than
  $200M across Series B, B+ and B2 rounds from investors including Qiming Venture Partners, HanKang Capital, CDH Investments,
  Sherpa Capital, YuanBio Venture Capital and Genesis Capital. AusperBio sells therapeutics, not software: it publishes no
  developer program, no public API, no SDK and no machine-readable API contract. Its only machine-readable surface is the
  private Spring Boot CMS backend that renders ausperbio.com, whose springdoc API description is correctly locked behind authentication.'

  state: none
  reason: not-a-software-company
  detail: AusperBio develops antisense-oligonucleotide and siRNA drugs for chronic hepatitis B, so there is no software product
    to expose; ausperbio.com is a Vue single-page app that returns an identical 2,601-byte shell (md5 519d85ce…) for every
    path including invented ones, and the only machine-readable API description on the estate is the springdoc description
    of the private Spring Boot CMS at cms.ausperbio.com/jzy-admin/, which is correctly 401-gated and is site infrastructure
    rather than a product surface.

    note: Soft 404 — byte-identical to the SPA shell returned for a nonexistent control path.

    status: 200
    note: Control path proving every 200 on this host is the SPA catch-all.
