description: 'OrsoBio is a privately held, clinical-stage biopharmaceutical company founded in 2021 and headquartered in Palo
  Alto, California, developing first-in-class oral therapies that restore energy homeostasis in patients living with severe
  metabolic disorders — obesity, type 2 diabetes, severe dyslipidemias, lipodystrophies and MASH. The name is drawn from the
  metabolic adaptability of bears ("orso" in Italian). Its pipeline is led by three mitochondrial protonophores — TLC-6740,
  TLC-1180 and TLC-1235 — intended to increase energy expenditure and improve metabolic and cardiovascular health, alongside
  an LXR inverse agonist (TLC-2716) for severe hypertriglyceridemia and MASH, an ACC2 inhibitor (TLC-3595) for insulin sensitivity
  in type 2 diabetes, and an ACMSD inhibitor to augment NAD+ biosynthesis in metabolic and inflammatory liver and kidney disorders.
  The company closed an oversubscribed $67 million Series B in September 2024, co-led by Ascenta Capital and Woodline Partners
  with participation from Samsara BioCapital, Enavate Sciences and Longitude Capital. OrsoBio publishes a corporate site covering
  its science, pipeline, team, board, publications, events and press releases, but runs no developer program: no API documentation,
  no SDKs, no developer portal, no GitHub organisation and no machine-readable API contract of any kind. The only machine-readable
  surface on orsobio.com is the site''s own WordPress CMS route index, which the site''s robots.txt explicitly disallows at
  /wp-json/ and which is therefore not harvested or catalogued here.'

  detail: OrsoBio is a clinical-stage biopharmaceutical company with no developer program — no api., developer., docs., portal.
    or status. host resolves for orsobio.com, no orsobio GitHub organisation exists, and every spec path and /.well-known/
    document on the corporate site is answered by a SiteGround CAPTCHA interstitial that resolves to the site's WordPress
    404 page, leaving only the CMS routes at /wp-json/ that the site's own robots.txt disallows.
