Tokyo, Japan A transformative leap in Japan’s regenerative medicine landscape is underway as NKGen Biotech, a US-based clinical-stage biotech innovator, partners with HekaBio K.K., a leading Japanese healthcare company, to introduce Troculeucel, a cutting-edge natural killer (NK) cell therapy for neurodegenerative diseases.

This bold collaboration aims to fast-track the development, regulatory approval, and commercial rollout of Troculeucel, an autologous, non-genetically modified NK cell therapy designed to target debilitating conditions such as Parkinson’s and Alzheimer’s disease.

What’s New with Troculeucel?
Unlike traditional therapies, Troculeucel leverages the patient’s own immune cells to tackle complex neurodegenerative conditions, without relying on genetic modifications. Approved under Japan’s regenerative medicine framework, the therapy offers a fast-track path for patient access a much-needed development in a country facing rising dementia-related health challenges due to a rapidly aging population.

HekaBio’s Strategic Edge
With deep regulatory know-how and strong domestic partnerships, HekaBio is taking the helm of clinical trials in Japan, ensuring troculeucel reaches its first Japanese patients within the next 12 months. The company has also made a significant equity investment in NKGen, underlining its commitment to the long-term success of the therapy in Asia.

“HekaBio’s clinical and commercial expertise will allow us to navigate Japan’s regulatory environment efficiently, making Troculeucel more accessible for those who need it most,” said Dr. Paul Y. Song, CEO of NKGen Biotech.

Rob Claar, CEO of HekaBio, added, “Japan is facing an aging crisis with increasing neurodegenerative diseases. Our collaboration with NKGen brings a revolutionary therapy that has the potential to redefine treatment pathways for millions.”

Why It Matters
This alliance not only strengthens Japan’s position in regenerative medicine but also paves the way for personalized, cell-based therapies to become mainstream in neurodegenerative treatment. Troculeucel could mark the beginning of a new era where natural immunity is enhanced, not replaced, to fight age-related diseases.
