About Variant Bio 

Variant Bio is developing life-saving therapies by studying the genes of people with exceptional health-related traits. By identifying communities with unique genetic architectures and outlier phenotypes, Variant Bio has identified novel human genetic evidence that is the basis for programs with breakthrough potential across multiple therapeutic areas. The company’s research is powered by its proprietary VB-Inference platform, which integrates across deep phenotyping and multi-omic data using statistical genetics and AI/ML approaches to identify and validate therapeutic targets. With ethics at its core, the company launched an unprecedented benefit-sharing program in 2020, in which it has pledged tangible benefits that directly impact the communities it partners with throughout the world. Variant Bio is now poised to advance multiple potentially life-changing therapeutic programs toward the clinic, and to create concomitant value for partner communities who have entrusted the company with their genetic data.

What is Variant Bio’s origin story?

  • Variant Bio was founded in 2018 by Kaja Wasik, PhD, and Stephane Castel, PhD, and is headquartered in Seattle, Washington. Kaja and Stephane met while studying genetics at Cold Spring Harbor Laboratory. After graduating, Kaja went on to become Chief Scientific Officer and a co-founder of Gencove, a genomic technology company that was the first to commercialize low-pass whole genome sequencing. Stephane completed a postdoctoral research fellowship at the New York Genome Center studying the molecular mechanisms underlying genetic associations to disease. Kaja and Stephane shared a passion for doing research with scientific and moral impact and, together, they formed the core scientific thesis of Variant Bio: to engage diverse participants in genomic studies that use cutting edge approaches to better capture the entire genome and to discover novel targets for drug discovery. 

Who works at Variant Bio?

  • Our team is 40 employees strong, with expertise spanning genetics, drug development,  molecular biology, chemistry, anthropology, and ethics. We are united in the belief that human genomics has the power to transform drug development.
  • Meet the full team including our Advisors, Board of Directors, Ethics Advisory Board, and Scientific Advisory Board.

What role do anthropologists play at Variant Bio? 

  • Variant Bio co-designs genomic research studies with local researchers in association with partnering communities and is committed to sharing research findings with them. Because of the company’s emphasis on community-engaged research, anthropologists were among the earliest hires at Variant Bio. They helped frame, design, and implement a community engagement model that Variant Bio employs to elicit pre-study feedback as well as input on benefit sharing and the return of results. Anthropologists' deep understanding of diverse cultural contexts is critical for a company like ours that seeks to carry out transparent and respectful, informed collaboration with communities around the world. 
  • See an example from Madagascar of how anthropologists from Variant Bio work with study partners to carry out co-designed, community-engaged research. 

Where does Variant Bio have projects? 

  • To date, the company has built a foundation of more than 20 genomic research partnerships across six continents – including locations such as the Faroe Islands, Indonesia, South Africa, New Caledonia, Madagascar, and French Polynesia – and has spent the last several years developing novel insights based on these collaborations. 
  • See our project map here

How does Variant Bio identify partners to work with? 

  • We form research collaborations throughout the world with communities, academics, healthcare professionals, disease experts, hospitals, laboratories, industry partners, and biobanks. 
  • We look for populations or cohorts with unique and medically relevant health traits and a genetic architecture that facilitates drug discovery and development.
  • The therapeutic areas we currently focus on include inflammatory, fibrotic, and kidney diseases, and we are always expanding our existing pipeline.
  • For those interested in forming a partnership with Variant Bio, we can be reached at  

What is Variant Bio’s benefit-sharing program?

  • Variant Bio was created from the ground up with ethics at its foundation and is committed to partnering with individuals, communities, and researchers around the world in a way that respects the privacy, beliefs, cultures, and data of study participants. Variant Bio believes in a long-term commitment to partner communities and in providing product access and long-term benefit sharing to those communities who have contributed to Variant Bio’s genomics database. To help achieve those objectives, Variant Bio created the Affordable Medicines Pledge and a Benefit-Sharing Pledge.
  • In the short term, benefits can include support for local healthcare, environment, education, and cultural initiatives. In the long term, the company has pledged to share 4% of revenue plus 4% of its equity value with partner communities.

How much money has Variant Bio raised to date?

  • The company has raised $130mm to date from a top-tier syndicate of biotech and tech investors, including Lux Capital, General Catalyst, Alta Partners, SoftBank, Cercano Management, Casdin Capital, Sahsen Ventures, and others.

What is Variant Bio’s therapeutic pipeline? 

  • Our pipeline includes multiple programs at several stages, and our priority therapeutic areas of interest are inflammation-immunology, fibrosis, and kidney diseases. We focus on both common and orphan indications with an emphasis on delivering precision medicines to patients with diseases of great unmet medical need. We exclusively pursue novel targets and fully leverage orthogonal datasets – such as tissue mRNA and protein expression patterns – to guide the selection of compelling opportunities. Both small molecule and biologics drug discovery campaigns are rapidly implemented giving rise to programs in advanced stages of preclinical optimization and to selection of clinical candidates. 
  • See an updated pipeline here

What is Variant Bio’s current focus?

  • Based on findings from our research around the world, we are now focused on developing successful drug candidates that we can advance to clinical trials. Our long-term goal is to improve the health of patients around the world, and to share the financial benefits of our success with the communities who partner with us.
