SiSaf is delivering on the promise of RNA therapeutics to transform the treatment of disease

Our Story

The company’s Founder and CEO, Dr Suzanne Saffie-Siebert, had the vision of a new generation of hybrid drug delivery technology that would combine lipid nanoparticles with bioabsorbable silicon.

Suzanne’s vision was rooted in years of experience with both liposomes and silicon. She did her PhD thesis on the incorporation of plasmid DNA into liposomes and helped pioneer drug delivery with porous silicon at pSiMedica, a spin-out of Qinetiq. She hypothesized that silicon could be used to stabilize lipid nanoparticles and that in turn lipids would help control the biodegradation of Silicon.

With this vision, SiSaf began operating in 2008 with funding from Invest NI and the investment arm of the University of Ulster.

 

During SiSaf’s foundational years a small team worked on developing and optimising the new hybrid technology and generating safety and efficacy data. These data enabled SiSaf in 2016 to secure Series A funding to pivot from a University-based pre-seed company to an emerging biopharma company commercializing its delivery technology.

In 2019, Suzanne Saffie-Siebert made the strategic decision to focus SiSaf’s R&D activities on nucleic acid-based medicines. The company entered into a license and research agreement with the University of L’Aquila, Italy, for the development of siRNA therapies for rare skeletal diseases and partnered with Avellino Labs USA to co-develop topical gene therapies for corneal dystrophies.

In 2023, SiSaf’s lead program in Osteopetrosis received Orphan Drug Designation and Rare Pediatric Disease Designation from the FDA and the clinical path to IND has been agreed.

Our IP

 

SiSaf has built a continuously growing patent portfolio for both its pipeline and its technology.

A comprehensive patent landscape review by UK and U.S. patent attorneys concluded that SiSaf’s Bio-Courier technology is unencumbered by third-party rights and provides extensive freedom to operate.
