Sapreme Unveils its Proprietary Endosomal Escape Platform in Presentations at 16th Annual Meeting of Oligonucleotide Therapeutics Society

UTRECHT, The NetherlandsSeptember 28, 2020–(BUSINESS WIRE)–Sapreme, a biotechnology company focused on improving the delivery and efficacy of macromolecule therapeutics, today announced positive preclinical data on its proprietary endosomal escape platform in two presentations at the 16th Annual Meeting of the Oligonucleotide Therapeutics Society (OTS), held virtually from September 27th to 30th, 2020.

Sapreme is developing macromolecule delivery methods based on compounds that release therapeutic cargo from the endo-lysosome, improving access to intracellular targets and enhancing the therapeutic window for these therapeutics. Current macromolecular biologics rely on receptor-mediated endocytic uptake into the endosome and inefficient passive release from these vesicles into the cell to achieve therapeutic efficacy. The company’s presentations demonstrate that Sapreme’s SPT001 compound improves intracellular release of targeted antisense oligonucleotides (ASOs) and thereby also their therapeutic efficacy. In addition to ASOs, SPT001 has also been demonstrated to enhance delivery of other targeted payloads such as antibody-conjugated toxins.

“The data presented today underscore the broad potential of our platform to overcome endosomal entrapment and improve the therapeutic window of macromolecule therapeutics,” stated Guy Hermans, Ph.D., Chief Executive Officer of Sapreme“We are encouraged to see that conjugating SPT001 to liver or tumor targeted ASOs leads to significantly improved silencing, with positive implications for development of metabolic syndrome and oncology targeting drug developments. These results support the further development of SPT001 as the delivery mechanism of choice for future intracellularly active macromolecular drug candidates.”

The presentations are available on demand at the 16th Annual Meeting of the OTS conference website through this link.
