VALENCIA, SPAIN, SEPTEMBER 2, 2025
At Curapath, our mission has always been to push the boundaries of non-viral drug delivery. Today, we are proud to announce a strategic partnership with Cayman Chemical that will make our proprietary PEG-free shielding lipids more accessible to researchers worldwide.
Through Cayman’s extensive global distribution network, scientists will now be able to source Curapath’s polysarcosine (pSar) and polyaminoacid-based shielding lipids for use in lipid nanoparticle (LNP) development, supporting applications in gene therapy, mRNA vaccines, and biologic drug delivery. Additional high-quality polymers, including poly(lysine) and poly(glutamic acid), as well as cationic polymers optimized for gene transfection, will also become widely available.
Developed and manufactured at our headquarters in Valencia, Spain, Curapath’s pSar lipids provide a non-toxic, non-immunogenic, and biodegradable alternative to traditional PEGylated lipids, without compromising efficacy in LNP formulations.
PEGylated lipids have long been used to shield LNPs from immune detection, but their association with immunogenicity and adverse reactions is driving the search for better solutions. Our PEG-free polymers address these challenges head-on, giving researchers a safe and effective option to advance next-generation therapies.
At Curapath, we believe this collaboration is more than just product availability — it’s about accelerating innovation. By combining Cayman’s global reach with our science-driven innovation and GMP manufacturing expertise, we are helping researchers translate their discoveries into real therapeutic impact.
