bit.bio’s lead cell therapy candidate (bbHEP01) is in development as a treatment for patients suffering from acute liver failure (ALF) and acute-on-chronic liver failure (ACLF), considered life-threatening liver conditions with high mortality. bbHEP01 consists of encapsulated allogeneic induced hepatocyte-like cells (txHepatocytes) produced by bit.bio’s opti-ox™ precision cell programming technology. The product is designed to provide transient liver function support, allowing native liver recovery or providing a bridge to transplant. This approach builds on current preclinical and clinical data demonstrating the feasibility and potential benefit of encapsulated donor-derived hepatocyte cell therapy 1-5.
A key challenge for the development of hepatocyte cell therapies is access to liver cells of sufficient quality and quantity. bit.bio’s precision cell programming technology opti-ox™ solves this bottleneck by providing a consistent and scalable supply of highly functional txHepatocytes. Initial clinical data are expected in 2026.
Mark Kotter, CEO at bit.bio said:
“bit.bio’s mission is to democratise access to cell therapies. Our growing portfolio of therapeutic bit.bio txCells™ will enable a broad pipeline of regenerative and immune cell therapies, which we will develop either independently or in collaboration with external partners. I’m excited to welcome Drs. Katy Rezvani, Anil Dhawan and Loïc Vincent to our SAB. Drawing on the combined expertise of our expanded SAB, we will proceed rapidly and thoughtfully, taking a risk-based approach. We will focus on areas of high unmet medical need where clinical risk has been mitigated by prior clinical studies. Our lead development candidate in acute liver failure exemplifies this approach.”
Beyond bbHEP01 and additional opportunities in txHepatocyte cell therapy, bit.bio today also announced its broader therapeutic cell pipeline which includes pancreatic islet cells, GABAergic neurons and immune cells such as myeloid and natural killer (NK) cells. Each cell type has the potential to give rise to multiple product candidates, for example by using different cell product delivery methods, engineering modifications, or therapeutic targets. Initial development areas for these cell types include metabolism and endocrinology, immunology, and neurology.
bit.bio intends to balance internal development and partnered development opportunities to advance its pipeline. Collaborations, such as the recent announcement with BlueRock Therapeutics focused on regulatory T cell (Treg) based cell therapies, will form an important aspect of the company’s cell therapy development strategy.
The bit.bio SAB is chaired by stem cell pioneer Roger Pedersen PhD, and includes cell reprogramming visionary Marius Wernig PhD and world-renowned expert in artificial intelligence and machine learning Thore Graepel PhD. The three new members of the SAB announced today are:
- Anil Dhawan MBBS, MD, FRCPCH - liver cell therapy expert and Professor in Paediatric Hepatology at King’s College Hospital in London with a special interest in liver cell transplantation.
- Katy Rezvani MD, PhD - immune-oncology pioneer and Professor of Stem Cell Transplantation & Cellular Therapy at The University of Texas MD Anderson Cancer Center.
- Loïc Vincent PhD - oncology scientist with more than 20 years of biotech and pharma experience, and currently Chief Scientific Officer at Affini-T Therapeutics.
On joining the bit.bio SAB, Professor Dhawan said:
“With its unique precision cell programming technology, bit.bio has the solution to the key problem for cell based therapies - namely access to an affordable, scalable and consistent supply of human cells. I am so excited that bit.bio’s lead candidate builds on our previous work in liver disease, and I am looking forward to working with the bit.bio team to develop a life-saving treatment for the thousands of ALF and ACLF patients that so desperately need it.”

About bit.bio
bit.bio is a synthetic biology company focused on human cells that is advancing medicine (UN SDG9) and enabling curative treatments (UN SDG3). The company does this by industrialising the manufacture of human cells and making them more accessible. The company was spun out of the University of Cambridge in 2016 and has since raised approximately $200m from investors such as Arch Venture, Foresite Capital, Milky Way, Charles River Laboratories, National Resilience, Tencent, Verition Fund and Puhua Capital.
bit.bio’s opti-ox™ precision cell programming and manufacturing technology enables conversion of induced pluripotent stem cells (iPSCs) into any desired human cell type in a single step. This can be achieved within days and at industrial scale, while maintaining exceptional purity and unparalleled consistency.
Our discovery platform extends this approach to any desired cell type by identifying the transcription factor combinations that define cell states (including identity, cell subtype identity, maturity) using high throughput screens and advanced data analysis. We believe that opti-ox can revolutionise regenerative medicine similarly to how CRISPR is unlocking gene therapy.
bit.bio’s cell therapy pipeline, based on txCells™, is focused on serious diseases that lack effective treatments. Our current therapeutic development areas include metabolism and endocrinology, immunology and neurology. Our lead candidate, bbHEP01 based on txHepatocytes, is in development as a treatment for patients suffering from acute liver failure (ALF) and acute-on-chronic liver failure (ACLF) and is expected to enter clinical development in 2025. Complementing our internal pipeline, we have a collaboration with BlueRock Therapeutics (a wholly owned independently operated subsidiary of Bayer AG) focused on regulatory T cell (Treg) based cell therapies.
In addition, our extensive ioCells™ research cell product portfolio, which includes wild type, disease model human cells and CRISPR-ready cells, is opening up new possibilities for studying human biology and developing new medicines in both research and high throughput and high content drug discovery.
