NRG Therapeutics Secures $67.8M Series B to Advance Mitochondrial Therapies for Neurodegenerative Diseases
September 9, 2025
byFenoms Start-Ups
NRG Therapeutics, a Stevenage-based biotechnology company focused on mitochondrial therapeutics, has successfully raised $67,835,242 in a Series B round. This major milestone underscores the growing confidence in therapies targeting mitochondrial dysfunction - a key driver of debilitating neurodegenerative diseases like Parkinson’s and Alzheimer’s.
The round was led by an international syndicate including Omega Funds, British Business Bank, Brandon Capital, M Ventures (Netherlands), and Criteria Bio Ventures. This global mix of venture and biotech investors reflects the urgency and potential of mitochondrial-targeted treatments to address some of the most pressing unmet needs in medicine today.
Pioneering Mitochondrial Therapeutics
At its core, NRG Therapeutics is on a mission to harness mitochondrial biology to develop disease-modifying drugs. Unlike symptomatic treatments that only mask the effects of neurodegeneration, NRG’s therapies aim to protect and restore mitochondrial function - directly addressing the cellular energy crises that underpin neurological decline.
This approach positions the company at the cutting edge of biotechnology research, combining advanced pharmacology with breakthroughs in mitochondrial science. If successful, NRG could transform the treatment landscape for millions of patients worldwide living with neurodegenerative conditions.
Why Mitochondria Are the Key to Neurodegeneration
Mitochondria, often described as the “powerhouses of the cell,” play a pivotal role in cellular energy production. But in neurodegenerative diseases, these organelles break down, leading to energy deficits, oxidative stress, and ultimately, neuronal death.
By focusing on mitochondrial health, NRG Therapeutics is pursuing a strategy with broad applicability across multiple conditions:
- Parkinson’s Disease – linked to mitochondrial dysfunction in dopaminergic neurons.
- Alzheimer’s Disease – where impaired mitochondrial energy metabolism accelerates cognitive decline.
- ALS (Motor Neuron Disease) – mitochondrial failure contributes to rapid progression.
- Huntington’s Disease – where mitochondrial defects worsen neuronal vulnerability.
Instead of tackling individual symptoms, NRG is addressing a root cause mechanism - one that could redefine how we understand and treat brain diseases.
Building Global Momentum
This Series B funding equips NRG with the resources to expand clinical development, scale preclinical research, and strengthen its position as a category-defining biotech company in mitochondrial therapeutics.
Investors like Omega Funds and Brandon Capital bring decades of experience in advancing breakthrough biotech companies to market, while support from British Business Bank highlights the UK government’s commitment to fostering innovation in life sciences.
A Founder’s Insight That Can’t Be Ignored
One of the overlooked truths in biotech fundraising is that the science alone isn’t enough - what investors are truly backing is the pathway to translation and scalability.
Founders in deep-tech and biotech often get trapped in scientific storytelling, but what accelerates investor conviction is a clear roadmap from lab discovery → regulatory validation → commercial readiness. NRG exemplifies this: their mitochondrial science is world-class, but what unlocked this $67.8M raise is their ability to tie the biology to a credible path into human trials and eventual patient impact.
For founders outside of biotech, the same principle applies: you don’t just raise capital on innovation - you raise on execution clarity. Show how the money transforms your science into a product, your technology into adoption, or your platform into a system. Investors fund momentum, not just molecules.
Why Investors Are Doubling Down
The investor syndicate backing NRG represents not just capital, but also strategic networks in pharma, biotech, and healthcare infrastructure. Here’s why they’re leaning in:
- Global Health Demand: Neurodegenerative diseases are projected to affect over 152 million people by 2050 (Alzheimer’s Disease International).
- Unmet Need: Current drugs treat symptoms but do not halt or reverse disease progression.
- Market Potential: The neurodegenerative therapeutics market is expected to surpass $22 billion by 2030, driven by aging populations and rising disease prevalence.
- Mitochondrial Angle: By targeting a fundamental mechanism, NRG’s pipeline has the potential to cross multiple indications, making it a platform play rather than a single-asset bet.
Industry Outlook: The Rise of Mitochondrial Medicine
The biotechnology sector has seen surging interest in mitochondrial-targeted therapies, with multiple emerging players exploring drugs, gene therapies, and diagnostics. However, NRG stands out for its focus on neurodegeneration, where the need is greatest and the opportunity most urgent.
Some key industry stats that highlight the momentum:
- The global Parkinson’s disease drug market alone is projected to grow from $5 billion in 2023 to $8.8 billion by 2032 (Fortune Business Insights).
- Alzheimer’s, often called the “epidemic of the 21st century,” costs the global economy over $1.3 trillion annually (World Alzheimer Report).
- Investment in neuroscience-focused biotech is rebounding, with venture capital in CNS drug discovery increasing by 38% year-over-year in 2024 (PitchBook).
- Mitochondrial dysfunction has been implicated in over 50 diseases, widening the addressable pipeline for mitochondrial-focused therapies.
As the convergence of biology, technology, and investment intensifies, mitochondrial medicine is no longer niche - it’s becoming a mainstream frontier in biotech.
What’s Next for NRG Therapeutics
With its Series B secured, NRG is expected to:
- Advance its lead mitochondrial therapeutic candidates toward clinical trials.
- Expand partnerships with academic institutions and pharma companies.
- Strengthen its scientific and executive teams to accelerate growth.
- Position itself as a leader in the emerging mitochondrial medicine category.
If milestones are met, NRG will not only validate its approach but also establish itself as a biotech shaping the next era of neurodegenerative disease treatment.
Final Thoughts
NRG Therapeutics’ $67.8M Series B isn’t just a financing headline - it’s a signal that mitochondrial therapeutics are stepping into the spotlight. By addressing the cellular engines of neurodegeneration, NRG is moving toward solutions that could change the lives of millions of patients worldwide.
For investors, patients, and the biotech community, this is more than a funding round - it’s a pivotal step toward a future where neurodegenerative diseases can be slowed, halted, or even reversed.
