Living Cell Technologies (LCT) is an Australian biotechnology company dedicated to developing cell-based therapies for neurodegenerative diseases, with a primary focus on Parkinson's disease. Founded in 2007 and headquartered in Sydney, Australia, LCT is listed on the Australian Securities Exchange (ASX: LCT).
LCT's innovative approach utilizes encapsulated cell technology to deliver therapeutic proteins directly to the brain, potentially providing long-lasting disease modification rather than just symptom relief. The company's lead product, NTCELL, has completed Phase 1/2a clinical trials demonstrating sustained clinical benefits in Parkinson's disease patients.
Living Cell Technologies represents an emerging player in the cell therapy space, leveraging Australia's strong biotechnology sector and research infrastructure. The company's mission is to develop transformative cell-based treatments for diseases with significant unmet medical need.
¶ Mission and Vision
LCT's stated mission is to:
- Develop cell-based therapies that provide genuine disease modification
- Make cell therapy accessible for patients with neurodegenerative diseases
- Leverage Australia's research excellence in regenerative medicine

LCT's core technology is its encapsulated cell delivery platform, which addresses key challenges in cell-based therapy:
The encapsulation device consists of:
- Alginate-based semi-permeable membrane
- Pore size optimized to allow nutrient diffusion
- Selective permeability preventing immune cell entry
- Mechanical stability for long-term implantation
The encapsulation technology enables:
- Allogeneic cell use — porcine cells can be transplanted without immunosuppression
- No rejection risk — immune system cannot attack encapsulated cells
- Reduced infection risk — compared to traditional transplantation
- Safety switch — device can be removed if adverse events occur
A unique feature of the technology:
- Device can be stereotactically removed if needed
- Provides safety margin for first-in-human studies
- Allows treatment adjustment or discontinuation
The encapsulated cells provide therapeutic benefit through:
Choroid plexus cells secrete multiple neurotrophic factors:
- Glial cell line-derived neurotrophic factor (GDNF)
- Neurturin
- Nerve growth factor (NGF)
- Various supporting factors
These factors support:
- Survival of dopaminergic neurons
- Protection against oxidative stress
- Promotion of neurite outgrowth
- Enhancement of synaptic function
The choroid plexus cells naturally:
- Produce cerebrospinal fluid (CSF)
- Regulate intracranial pressure
- Support blood-brain barrier function
- Provide trophic support to neuronal populations
NTCELL is LCT's lead product, consisting of:
- Cell source: Porcine (pig) choroid plexus cells
- Delivery: Stereotactic implantation into the brain
- Target: Substantia nigra region
- Indication: Parkinson's disease
The rationale for NTCELL in PD includes:
- Replacement of lost neurotrophic support
- Protection of remaining dopaminergic neurons
- Potential for disease modification
- Long-lasting effects from single treatment
NTCELL implantation involves:
- Pre-surgical planning using MRI
- Stereotactic navigation to target brain regions
- Minimally invasive burr hole surgery
- Precise placement of encapsulated cells
- Post-operative monitoring
The first-in-human study enrolled patients with advanced Parkinson's disease:

Results:
- Primary endpoint met — statistically significant improvement
- Mean improvement in OFF-medication UPDRS motor scores
- Reduced levodopa-induced dyskinesias in subset of patients
- Sustained effects observed up to 5 years post-implantation
- No serious adverse events related to device
Planned confirmatory trial:
- Status: Planning and regulatory preparation
- Design: Randomized, sham-controlled
- Target: Larger PD patient population
- Endpoints: UPDRS improvement, dyskinesia reduction
LCT is exploring application of the platform to other neurodegenerative conditions:

GDNF delivery |
- GDNF has shown promise in HD models
- Encapsulated delivery may protect striatal neurons
- Company evaluating preclinical data package
Potential future applications include:
- Alzheimer's disease — trophic support for cholinergic neurons
- Motor neuron disease — neurotrophic factor delivery
- Stroke recovery — supporting neuronal repair
The landmark study published in Movement Disorders demonstrated:
- UPDRS Motor Score: Mean 30% improvement from baseline
- OFF-medication scores: Improvements persisted without medication
- Dyskinesia reduction: 40% reduction in levodopa-induced dyskinesias
- Duration: Effects sustained through 5-year follow-up
- No device-related serious adverse events
- No evidence of immune rejection
- No tumor formation
- Surgical complications similar to standard neurosurgery
Supporting biomarker work includes:
- PET imaging showing preserved dopaminergic function
- CSF biomarker analysis demonstrating neurotrophic activity
- Long-term safety monitoring
Partnership with DIatherix for:
- Development of next-generation encapsulation technology
- Manufacturing process optimization
- Quality control methods
Research collaboration including:
- Preclinical development
- Mechanism of action studies
- Clinical trial execution
LCT continues to explore:
- Pharmaceutical company partnerships for commercialization
- Academic collaborations for mechanism elucidation
- International clinical trial sites
LCT is working with Australia's Therapeutic Goods Administration (TGA) for:
- Orphan drug designation
- Priority review pathways
- Accelerated approval for serious conditions
Plans for global registration:
- FDA — Pre-IND meetings held, clinical trial plan in development
- EMA — Regulatory strategy for European markets
- Japan — PMDA consultation for Asian market entry
