AusperBio raised $120 million Series C on August 27, 2026. An unnamed strategic investor led. RA Capital joined. The company says capital raised since 2024 is now $360 million.

Unexpected truth: there is no valuation and no named lead. $360 million is a cumulative figure, not this close. AHB-137 is in Phase 3 in China and the company says it is not approved.

This page is for people deciding whether a late-stage HBV oligonucleotide print belongs on the August tape next to the AI mega-rounds. Last verified August 30, 2026. Facts below are the PR Newswire release.

Five-minute decision

If you need…Verdict
What happenedFunded. $120M Series C, Aug 27, 2026. No valuation.
Who ledUnnamed strategic investor. RA Capital is the named new name.
What AusperBio isOligonucleotide therapeutics for chronic hepatitis B. Not an AI copilot.
Whether it is shippingClinical. AHB-137 in Phase 3 in China. Not approved.
Whether to diligenceYes, if you underwrite functional-cure HBV. No, if you need a mark or a named lead first.

Investigate further when: you believe a Phase 3 ASO backbone plus a targeted siRNA is worth a nine-figure check without a published post-money.

Wait or pass when: you need the lead’s name, a valuation, or U.S. approval.

What AusperBio actually does

AHB-137 (company): an unconjugated antisense oligonucleotide from the Med-Oligo platform, designed to suppress hepatitis B surface antigen, inhibit viral DNA replication, and promote immune reactivation. Global Phase 1 and multiple Phase 2 studies are complete. A Phase 3 trial is running in China. Investigational. Not approved.

AHB-171 (company): a hepatocyte-targeted siRNA using the Au-HALO delivery platform. First clinical candidate from that platform. Also investigational.

Job: move chronic HBV from long-term viral suppression toward a functional cure. The release cites WHO figures of 254 million people with chronic HBV and about 1.1 million deaths a year. Those are company-cited WHO numbers, not our audit.

Same bucket (therapeutics still clears nine figures in 2026). Three different balance sheets.

Worked numbers (company figures)

Setup: AusperBio says it has raised $360 million since 2024. This close is $120 million.

Move: divide the new C by the cumulative figure.

Punch: this Series C is one-third of the disclosed 2024–26 stack — illustrative only. It tells you the C is large relative to the company’s own running total. It does not produce a valuation, a price per share, or a Phase 3 success probability.

When not to use this page

  • Do not treat $360 million as the August check. The August check is $120 million.
  • Do not invent a lead name or a valuation.
  • Do not write AHB-137 or AHB-171 as approved drugs.
  • Do not invent /fund/ pages for RA Capital, Qiming, Sherpa, HanKang, YuanBio, InnoPinnacle, or CDH.
  • Do not paste the WHO burden stats as if we measured them.
