Company Lands $17.2 Million to Preserve, Regenerate, and Manipulate the Thymus

The U.S. biotech company Tolerance Bio has recently launched with an impressive $17.2 million in seed financing aimed at developing thymus-based therapies for immune-mediated diseases. This innovative approach focuses on preserving, regenerating, and manipulating the thymus, an organ that plays a pivotal role in the induction of immune tolerance.

Based in Philadelphia, Tolerance Bio is on a mission to create an allogeneic cell therapy platform utilizing induced pluripotent stem cells (iPSCs), alongside developing pharmacological treatments directed at various immune diseases. By concentrating on the thymus, the company addresses fundamental aspects of immune regulation, particularly its preservation and restoration in cases of decline.

The thymus is often referred to as “the school for T cells” as it educates immune cells that help the body defend against infections and cancers while preventing autoimmune responses. Notably, this essential organ begins to atrophy after the early years of human life, leading to an increased vulnerability to immune disorders and higher mortality rates.

Understanding Thymic Dysfunction

Thymic dysfunction can be attributed to age-related decline, congenital defects, or damage induced by medical interventions such as surgery, chemotherapy, and infections. Tolerance Bio intends to reverse these adverse effects by:

  • Developing artificial thymuses using stem cell technologies.
  • Introducing disease-specific treatments through thymic organoids.
  • Creating pharmacological options to delay thymic involution and prevent both natural and accelerated decline.

By restoring thymic function, the company aims not only to tackle immune diseases but also to potentially extend healthy lifespan through improved immune responses.

“Defeating immune diseases has been the lifelong quest of this exceptional team we have assembled, with patients and their families always front and center for us.” – Dr. Francisco Leon, Co-founder and CEO of Tolerance Bio

Alternative Therapies and Scientific Foundations

Tolerance Bio joins a growing cohort of companies that aim to leverage the power of the thymus in the fight against aging and disease, including organizations backed by the Advanced Research Projects Agency (ARPA). Noteworthy strides have been made previously, such as a 2015 clinical trial initiated by Dr. Greg Fahy, a significant figure in aging research, who explored the possibility of thymus regeneration as a means to reverse certain aspects of human aging.

According to preliminary results, participants showed promising improvements following thymus regeneration treatments.

Research Foundation and Investment

Tolerance Bio’s scientific endeavors are deeply rooted in iPSC technologies that were originally developed at the University of Colorado and the University of Florida, under the guidance of Dr. Holger Russ. Russ expressed enthusiasm regarding the advance of this promising technology:

“After pioneering the generation of bioengineered thymuses from iPSCs in vitro and in vivo, I am very excited for the opportunity to advance this technology to benefit patients.”

The recent financing round was led by Columbus Venture Partners, with contributions from Criteria Bio Ventures, Sessa Capital, BioAdvance, and Ben Franklin Technology Partners, among others. These funds will facilitate Tolerance Bio's progression towards clinical trials for their pioneering therapies.

“With Tolerance Bio, we not only have the prospect of preventing and treating immune disease but also possibly extending longevity, a tremendously exciting opportunity,” noted Damia Tormo, Managing Partner of Columbus Venture Partners.

Conclusion

Tolerance Bio's innovative approach in leveraging the thymus holds transformative potential for both immune health and longevity. As research progresses, the implications of their findings could serve as a beacon of hope for individuals suffering from immune disorders and for those interested in extending their healthy lifespan.
