NEW PATH FOR CARTILAGE

We regenerate
cartilage

Not just pain relief — a First-in-Class therapy that rebuilds the cartilage itself.

ONE HEALTH STRATEGY

Dogs first,
then people

Led by a canine osteoarthritis therapy, advancing into human medicine.

COMPANY

A drug discovery company
built on 30 years of science

Founded in 2023 by Professor Yongwon Choi (University of Pennsylvania) and Professor Soo Young Lee (Ewha Womans University) — long-time collaborators since The Rockefeller University — to regenerate cartilage and resolve autoimmune inflammation.

PIPELINE

Three programs for
high unmet medical need

Diversified across osteoarthritis, autoimmune disease and immuno-oncology.

01

NPB001

OSTEOARTHRITIS

A small molecule that blocks OSCAR–collagen binding to regenerate cartilage.

02

NPB002

AUTOIMMUNE

An antibody that calms inflammation across arthritis, sepsis, IBD and psoriasis models.

03

NPB003

IMMUNO-ONCOLOGY

An immuno-oncology antibody that blocks a novel immune target in melanoma and lung cancer.

Preclinical results are not predictive of clinical outcomes.

EVIDENCE

Cartilage regrew
after disease had set in

Knee cartilage of a normal mouse without induced osteoarthritis

Four osteoarthritis measures showing lower scores in the NPB001 group than in the placebo group

The red layer is cartilage. It thinned and was lost in the placebo group, while NPB001 restored cartilage thickness.

Across all four measures, NPB001 (blue bars) scored markedly lower than placebo (red bars). Safranin O staining · DMM mouse model. NPB001 was dosed after degeneration had already progressed, yet the cartilage layer recovered.

Built on foundational work in Nature, J. Clin. Invest., PNAS and Nature Communications.

ONE HEALTH

Dogs first,
then people

One foundational technology takes on joint health in both animals and people — beginning with canine osteoarthritis and advancing into human medicine.
