In the last few days there have been news about Sangamo Therapeutics ($SGMO), which for me are more than just headlines:
âĄïž a new patent for the further development of zinc finger technology
âĄïž and a sign of life from the paused TX200 program
Both show that Sangamo continues to expand its platform - quietly but steadily. âïž
1ïžâŁ New patent: "Engineered Genetic Modulators"
On October 9, 2025 a new patent was published at the US Patent and Trademark Office (USPTO):
US20250313848 - "Engineered Genetic Modulators" which you can view here đhttps://tinyurl.com/3e8d2bpr
(the original patent US20200109406 from April 9, 2020 can be found here đ https://tinyurl.com/mry9rhxp - If the two links do not work, simply go to https://ppubs.uspto.gov/pubwebapp/static/pages/ppubsbasic.html and enter the respective patent number without the suffix "US" in the search field)
This new patent extends Sangamo's Zinc Finger Platform (ZFP) - the molecular tools the company uses to controls genesinstead of cutting them cutting them up.
While many competitors still rely on CRISPR a technology that permanently alters DNA - Sangamo has long been working with a more precise, controllable systemthat modifies genes like a dimmer instead of irrevocably rewriting them. This is an enormous safety advantage, especially in the nervous system.
In short: CRISPR cuts - Sangamo directs. And this is exactly what the next generation of patents is being created for - a new era of controllable gene therapy.
2ïžâŁ TX200 - the "paused" program lives on
Almost at the same time there was a sign of life on LinkedIn:
Sangamo shows there that the CAR-Treg program TX200 - developed to prevent rejection reactions after kidney transplants - is still scientifically active.
đĄ The special feature: TX200 was the world's first clinically approved CAR-Treg program. Sangamo was therefore a pioneer - and made clinical history long before other players emerged in this field.
Pausing this program was not a setback, but a strategic decision: The program is expensive, complex and needs partner capital - but scientifically it is fully intact. Instead of suppressing the immune system, it is "retrained" to accept the donor organ - a completely new immunological approach.
The Nobel Prize and the fact that Sangamo is now taking up the topic again publicly shows that the platform is alive - and remains relevant: The platform is alive - and remains relevant.
đ§ Background: The zinc finger platform - Sangamo's silent backbone
If you want to understand Sangamo, you have to understand the technology. The company works with zinc finger proteins (ZFPs) - tiny DNA binders that precisely switch genes switch genes on or off, correct or regulate them. or regulate genes. Ingenious!
This results in three pillars of application:
1ïžâŁ Gene regulation - Switching genes on or off in fine doses (e.g. ST-503, ST-506, tauopathies with Genentech)
2ïžâŁ Gene editing - Correct DNA sequences permanently (e.g. sickle cell)
3ïžâŁ CAR-Tregs - Programming immune cells (e.g. TX200)
And in order for these therapies to reach the brain at allSangamo is also developing its STAC-BBB delivery platform - a kind of molecular transporter that carries genetic therapies across the blood-brain barrier.
This platform is unique in the industry and is already being used by:
- Genentech / Roche (tauopathies)
- Astellas (exclusive license for up to five CNS targets)
- Eli Lilly (parallel license package with up to USD 1.4 billion milestone potential)
Sangamo earns from license fees, milestones and royaltieseven when others are in the spotlight.
đŻ Conclusion - Two small pieces of news, but one big pattern:
Sangamo remains true to its line - focused, data-driven and long-term. Not a hype story, but an example, how quiet pioneers are building the future step by step.
đ And one final thought
Now there are visible triggers - and that changes everything:
đč The new patent confirms the further development of the platform
đč TX200 shows activity again
đč ST-503 starts clinically
đč Fabry is about to be approved
đč Further partnerships are on the horizon
Sangamo has never had this combination before. It looks to me like the company is on the verge of a real revaluation - scientifically, strategically and perhaps now also on the stock market again đ€đ
What fascinates me again and again: Sangamo has the technology that others are still looking for. While companies like CRISPR Therapeutics ($CRSP) (-4.47%) or Intellia ($NTLA) (-3.72%) are being criticized for their gene scissors âïžgefeiert, Sangamo has long been working on the next generation - more more precise, safer, reversible. Not a one-way street in the genome, but real control.
Looking back, I think it's fair to say that Sangamo was ahead of its time - a pioneer when the world wasn't even ready. Today, everything fits together: Data, platform, partners, momentum. When the market finally recognizes this, we won't be talking about percentages - but about breakthroughs that make history. đ
