Innate immunity, trained immunity & myeloid cells

Recent advances in immunology reveal that the innate immune system does more than fight infections—it adapts and evolves in remarkable ways.

Pioneering research by Trained Therapeutix Discovery founders has shown that innate immune responses can be “trained” through epigenetic changes stored in bone marrow progenitor cells. These adaptations, while powerful, can sometimes turn harmful, driving chronic inflammation in conditions like autoinflammatory and cardiovascular diseases. Additionally, recent publications highlight how tumors can remotely reprogram myeloid progenitor cells in the bone marrow, opening new avenues for therapeutic intervention.

Recognizing the potential of these discoveries, Trained Therapeutix Discovery is developing innovative nanomedicines based on apolipoprotein nanoparticles, which were invented by Trained Therapeutix Discovery founders. These nanomedicines are designed to precisely target and reprogram myeloid progenitor cells in the bone marrow, offering a novel approach to innate immunotherapy. By harnessing the adaptability of the innate immune system, Trained Therapeutix Discovery aims to address unmet needs in autoinflammatory diseases and cancer.

The nanomedicine platform

Apolipoprotein A1 is natural protein responsible for lipid transport in the human body. Trained Therapeutix Discovery recombinantly produces apolipoprotein A1 and applies it as a scaffold that retains lipids to form nanoparticles. Using a proprietary manufacturing process, nanoparticles with diverse, yet highly defined morphologies are generated. These nanoparticles are exclusively built from natural molecules and therefore have inherent tropism for myeloid (progenitor) cells in the bone marrow and are very well tolerated by the human body.

Therapeutic payloads are linked to lipids for their straightforward integration into the apolipoprotein nanoparticles to form bone-marrow targeted nanomedicines.

Trained Therapeutix Discovery Lead Programs

RIDE-001 is Trained Therapeutix Discovery’s immuno-oncology program.

RIDE-001 is a pioneering nanomedicine designed to target myeloid progenitor cells in the bone marrow. By inducing durable trained immunity, RIDE-001 reprograms the immune system to produce anti-tumor myeloid cells, directly combating cancer by empowering innate defenses.

 

RIDE-002 is Trained Therapeutix Discovery’s autoinflammation program.

RIDE-002 is an innovative nanomedicine that targets mTOR in myeloid (progenitor) cells to manage inflammation at its origin, favorably rebalancing the immune system, without systemic immunosuppression.
