Headquarters: Tokyo, Japan
Type: Biotechnology Company
Founded: 2017
Focus: Regenerative medicine, disease-modifying therapies for neurodegeneration
Renascience is a Tokyo-based biotechnology company dedicated to developing regenerative medicine approaches and disease-modifying therapies for neurodegenerative diseases. The company combines stem cell technology with novel therapeutic modalities to address the underlying causes of conditions like Alzheimer's disease and Parkinson's disease.
Renascience's mission is to develop transformative therapies that can repair or replace damaged neural tissue in neurodegenerative diseases. Rather than just slowing disease progression, the company aims to develop treatments that can actually restore neurological function.
Renascience has developed advanced stem cell-based technologies:
iPSC-Derived Neural Cells
- Generation of dopaminergic neurons from patient-derived induced pluripotent stem cells (iPSCs)
- Cortical neuron production for Alzheimer's disease applications
- Specialized glial cells for support and immunomodulation
Cell Banking
- Repository of characterized iPSC lines from healthy donors and patients
- Quality-controlled cell products for therapeutic use
- Scalable manufacturing processes for clinical production
Renascience integrates gene therapy approaches:
Neurotrophic Factor Delivery
- AAV-mediated delivery of neurotrophic factors like BDNF and GDNF
- Targeted expression in specific brain regions
- Regulated expression systems for controlled protein production
Gene Editing
- CRISPR-based approaches for correcting genetic mutations
- Enhanced trophic factor expression
- Modulation of disease-associated gene expression
Regeneration-Promoting Compounds
- Small molecules that enhance neural regeneration
- Promote axonal sprouting and circuit reconstruction
- Support survival of transplanted cells
Approach: iPSC-derived dopaminergic neuron transplantation
Indication: Parkinson's disease
Stage: Preclinical
RS-001 is Renascience's lead program, involving transplantation of dopaminergic neurons derived from human iPSCs into patients with Parkinson's disease. This approach aims to replace the dopaminergic neurons that are lost in Parkinson's disease, potentially reversing motor symptoms.
Program Features:
- Robust differentiation protocols for dopaminergic neuron production
- Characterization of cell purity and functionality
- Preclinical studies showing efficacy in animal models
- Plans for clinical-scale manufacturing
Approach: iPSC-derived neural progenitor cells
Indication: Alzheimer's disease
Stage: Discovery
RS-002 targets Alzheimer's disease using neural progenitor cell transplantation. These cells are designed to provide neuroprotection, support neural circuit function, and potentially replace lost neurons.
Approach:
- Generation of neural progenitor cells with enhanced survival properties
- Development of cells that integrate into existing neural circuits
- Combination with small molecule support for optimal engraftment
Approach: Gene therapy for BDNF delivery
Indication: Alzheimer's disease
Stage: Discovery
RS-003 uses AAV-based gene therapy to deliver Brain-Derived Neurotrophic Factor (BDNF) to the brain. BDNF is a key neurotrophin that supports neuron survival and synaptic plasticity, both of which are impaired in Alzheimer's disease.
Features:
- Novel AAV serotype with enhanced brain penetration
- Regulated expression system for controlled BDNF levels
- Potential for long-lasting therapeutic benefit from single administration
Renascience has established manufacturing capabilities for cell therapy products:
Cell Production Facility
- GMP-compliant cell manufacturing facility in Tokyo
- Scalable production processes for clinical supply
- Rigorous quality control testing for cell products
Gene Therapy Manufacturing
- AAV production capabilities for gene therapy programs
- Encapsulation technologies for controlled delivery
Renascience has a strategic partnership with Kyoto University for:
- iPSC technology development and optimization
- Stem cell differentiation protocols
- Clinical translation expertise
Collaboration on:
- Neural circuit reconstruction
- Gene therapy vector development
- Preclinical efficacy models
¶ National Center of Neurology and Psychiatry (NCNP)
Partnership for:
- Clinical development planning
- Patient access and clinical trial design
- Regulatory pathway guidance
Renascience plans to advance its programs through clinical development:
- Preclinical development: Complete IND-enabling studies for lead program
- First-in-human trials: Initiate Phase 1/2 trials in Parkinson's disease
- Expansion: Extend to Alzheimer's disease and other indications
- Combination approaches: Integrate cell therapy with small molecule support
