Selecta Biosciences Announces Publication in Nature Nanotechnology Describing Novel Approach for Improving the Efficacy and Safety Profile of Biologic Drugs
- Published results from preclinical studies show the potential of Selecta’s proprietary SVP-Rapamycin (SEL-110) immune therapy to improve the efficacy and safety of biologic therapeutics
- The data support Selecta’s lead clinical program, showing Selecta’s SVP-Rapamycin (SEL-110) induces antigen-specific immune tolerance and prevents the formation of anti-drug antibodies (ADAs) to biologic drugs, including pegsiticase (for gout) and adalimumab (for rheumatoid arthritis)
“Undesired immune responses affect both the efficacy and safety of marketed biologic therapies and the development of otherwise promising new technologies. Selecta’s SVP platform positions the company to enhance biologic therapy and to advance a pipeline of proprietary products that meet the therapeutic needs of patients with rare and serious diseases,” said
In the Nature Nanotechnology journal article,
Data presented in the journal article support the Company’s clinical lead program in gout, showing that intravenous co-administration of tolerogenic nanoparticles with pegylated uricase inhibited the formation of ADAs in mice and nonhuman primates and normalized serum uric acid levels in uricase-deficient mice. Underscoring the broad potential of the approach, results additionally show that subcutaneous co-administration of nanoparticles with adalimumab durably inhibited ADAs, resulting in normalized pharmacokinetics of the anti-TNFα antibody and protection against arthritis in TNFα transgenic mice.
In the published research, the induction of specific immune tolerance by SVP-Rapamycin (SEL-110) versus chronic immune suppression is supported by the findings that: (1) antigen must be co-administered at the time of SVP-Rapamycin (SEL-110) treatment; (2) immune tolerance is durable to many challenges of antigen alone; (3) animals tolerized to a specific antigen are capable of responding to an unrelated antigen, meaning that SVP-Rapamycin (SEL-110) does not induce a broad immune suppression; and (4) activation of naïve T cells is inhibited when adoptively transferred into previously tolerized mice. In contrast, daily administration of free rapamycin, at five times the total weekly rapamycin dose as that administered in the SVP-Rapamycin, was observed to transiently suppress the immune response, but did not induce durable immunological tolerance.
