Fighting cancer
at both ends of
the leash

We engineer living immune cells to fight cancer in pet dogs — and our discoveries are already reshaping the future of human cancer therapy.

Mission

Designer cell therapies for pets first — and their people next.

When a pet gets sick, families face limited options. LEAH Labs is changing that. We combine world-class gene editing with novel protein engineering to revolutionize companion animal oncology — while generating the insights that will power the next generation of human CAR-T therapies.

Translational medicine is in our DNA.
1st ever
We're the first, and only, in the world to put pets in remissions using CAR-T cell therapy in dogs with cancer.
The only CAR-T cell therapy company for dogs
World leading vets are testing CAR-T cells in pets, but we're the only ones doing this commercially.
Our trials are fully funded
We cover 100% of the costs for pet parents who enroll in our trials

Science

Purpose built for pets.
Advanced enough for humans.

Four pillars. One platform.

01

Generative Biology & De Novo Protein Engineering

Leveraging breakthroughs in AI and protein design, LEAH Labs designs, builds, and tests novel therapeutic assets that didn't evolve in nature. We're not iterating on legacy biology — we're inventing new biology from first principles.

02

Precision Gene Editing — GeneWeld

Our founder invented our gene editing platform during their PhD. This platform is a critical enabling technology that allows us to build CAR-T cell therapies at costs affordable to pet parents.

03

Harnessing Immune Cells to Fight Cancer

The immune system can detect and destroy cancer — but cancer evades it. Gene editing lets us reprogram T cells to become professional cancer-fighting assassins. CAR-T cell therapy is already curative in human blood cancers. We're bringing it their furry family members.

04

Canine Translational Oncology

Dogs develop the same spontaneous cancers as humans, in a shared environment, with a fully intact immune system. Disease in dogs mirrors disease in people. Every remission in a dog is a data point that accelerates human medicine — compressing timelines that would otherwise take a decade.

Clinical Trial

Our next clinical trial launches in May 2026

Our fully-funded clinical trial will be enrolling dogs diagnosed with B cell lymphoma. If you can travel to one of our three partner institutions, we want to hear from you. Treatment is provided at no cost to enrolled families.
