Overview

Ollin Biosciences develops biologics for vision-threatening retinal diseases. Lead candidate OLN324 is a VEGF/Ang2 bispecific antibody licensed from China's Innovent Biologics, targeting diabetic macular edema (DME) and wet age-related macular degeneration (wAMD). A Phase 1b study suggested potency and durability advantages vs Roche's Vabysmo per BioPharma Dive. In June 2026 Ollin closed an oversubscribed $330M Series B co-led by ARCH Venture Partners and TCGX, with a16z Bio+Health participating, to fund global Phase 3 trials starting second half 2026. Second program OLN102 targets thyroid eye disease.

Why Ollin Bio is interesting

China-licensed asset beat Roche's Vabysmo in Phase 1b head-to-head — $330M Series B (Jun 2026) from ARCH, TCGX, and a16z Bio+Health funds global Phase 3 starting H2 2026.

Product & use cases

Ollin is clinical-stage, not a platform — it develops injectable biologics for retinal vascular diseases. OLN324 aims to improve on anti-VEGF/Ang2 standards of care with less frequent dosing; OLN102 is a preclinical TSHR/IGF-1R bispecific for thyroid eye disease.

  • Treating diabetic macular edema with next-gen anti-VEGF/Ang2 therapy
  • Wet AMD patients needing longer-interval injections vs incumbent biologics
  • Future thyroid eye disease treatment via OLN102 pipeline
  • Global Phase 3 trials including U.S., China, and South Korea via Innovent partnership

Competitive landscape

Edge: Head-to-head Phase 1b data vs Vabysmo supports differentiation narrative; Innovent partnership provides China development leverage common in licensed-from-China biotech models.

Retinal injectable biologics are a multi-billion-dollar market dominated by Regeneron and Roche. Ollin's bet is a licensed bispecific can win on dosing interval and efficacy vs Vabysmo. Phase 3 execution and payer uptake determine outcome — $330M Series B signals crossover investor confidence but clinical risk remains high until pivotal readouts.

  • Roche Vabysmo direct

    Approved Ang2/VEGF bispecific gaining share from Eylea; Ollin explicitly targets superiority in Phase 3.

  • Regeneron Eylea incumbent

    Longtime market leader in retinal anti-VEGF; losing share to bispecifics but entrenched formulary presence.

  • Apellis / other retina entrants adjacent

    Multiple companies chase retinal disease with different mechanisms; crowded anti-VEGF class.

Notable stories

  • Ollin is part of a wave of U.S. biotechs built on medicines licensed from Chinese developers where Innovent is a frequent partner — BioPharma Dive (Jun 2026).
  • The $330M round was among the largest venture biotech financings of 2026, coming immediately after favorable Vabysmo comparison data.
