SOUTH SAN FRANCISCO, CALIFORNIA— May 9, 2023 — Parvus Therapeutics, a biopharmaceutical company developing the proprietary Navacim™ platform technology which triggers endogenous generation of regulatory T cells (Tregs) to provide organ specific immunoregulation without impairing normal immune function, announced today the publication of data showing: (i) that peptide-MHC class II-coated nanoparticles (Navacims) operate by triggering the expansion of cognate T follicular helper (TFH) cells and their immediate transdifferentiation into autoimmune disease-suppressing T regulatory type 1 (TR1) cells in vivo; and (ii) that BLIMP 1 is a gatekeeper for this novel cellular reprogramming event.

The data which identifies progenitor cells and describes the reprogramming sequence were published in an article published in the journal Cellular& Molecular Immunology: Solé et al. (2023), A T follicular helper cell origin for T regulatory type 1 cells. Cellular and Molecular Immunology. View

“The data described in this manuscript enhance our understanding of why and how Navacims re-program autoreactive T cells to comprehensively suppress organ-specific autoimmunity,” said Dr Pere Santamaria, the senior author of this publication and Parvus founder and chief scientific officer.

About the Parvus Navacim Platform
Navacims present a high-density array of peptide-MHCII complexes to cognate T cell receptors on autoimmune disease-relevant, autoantigen-experienced T cells, leading to the formation and expansion of cognate autoimmune disease-suppressing T-regulatory type 1 (TR1) cells in vivo. The resulting TR1 Treg cells specifically suppress autoimmune attacks in diseased organs through direct and bystander immunoregulation.

About Navacims™
Navacims are a novel first-in-class nanomedicine designed to treat autoimmune disease by selectively modulating disease-specific cellular responses without impairing normal immunity. Navacims specifically target and act only on disease causing effector T cells, delivering a signal that re-programs effector T cells to differentiate and expand into regulatory T (Treg) cells specific for self-antigens relevant to the patient’s disease. These disease- or tissue-specific Treg cells induce immunological tolerance to block undesired immune responses to self-antigens, while maintaining normal immune surveillance and activity.

About Navacim™ Manufacturing
Navacims, in their final form, represent a novel nanoparticle/protein molecule with targeted pharmacologic activity. Navacims are made by combining two types of component parts, each with precedent in drug development, found in approved therapeutics, and which are manufactured using well established processes. Specifically, the two component parts of Navacims are nanoparticles made from an iron oxide-core coated with polymer and peptide-major histocompatibility complex (pMHC) proteins. The unit operations to make a Navacim (polymerizing an iron core, CHO cell expression of the pMHC protein, purification with Protein-A, room temperature conjugation of the nanoparticle with the pMHC, and standard buffered saline drug product fill) are well established and readily available in a competitive ecosystem of qualified contract manufacturers.

Parvus is also eligible to receive certain additional milestone payments in other disease areas, as well as royalties on net sales of products resulting from the collaboration.

“Our collaboration with Genentech is now the second partnership that we’ve entered into with a major biopharmaceutical company, which we believe reinforces the potential of our Navacim immunoregulatory therapeutic platform,” said Curtis Ruegg, Ph.D., President & CEO of Parvus. “Partnering with Genentech will enable Parvus to expand the Navacim pipeline to address several debilitating autoimmune diseases in gastroenterology.”

Under the terms of the Agreement, Parvus will conduct pre-clinical development and clinical development activities through Phase I. Genentech will be responsible for clinical development from Phase II and beyond, including global regulatory submissions and worldwide commercialization of products.

“Parvus’ technology represents a potentially transformative approach for treating autoimmune diseases by inducing immune tolerance without causing generalized immune suppression,” said James Sabry, M.D., Ph.D., Global Head of Pharma Partnering, Roche. “In preclinical testing, Parvus’ platform has shown the ability to induce and expand disease-specific regulatory T cells, which restore immune system balance and halt the autoimmune disease process. We look forward to working with the Parvus team to hopefully bring this exciting advancement to patients.”

About Navacims™
Navacims are a precision medicine platform designed to trigger a naturally occurring immunoregulatory mechanism of the mammalian immune system which has evolved to protect against autoimmune disease. As selected for each disease, Navacims present a singular, peptide-major histocompatibility complex (pMHC) at supra-physiological density, targeting cognate T cell receptors (TCR) on disease relevant T cells. Navacim binding causes a sustained assembly of TCR microclusters and prolonged signaling leading to disease-specific type 1 regulatory T (TR1) cell differentiation. Because Navacim activity depends on the presence of disease-causing, autoimmune T cells, their action is self-limiting. In preclinical disease models, Navacims have demonstrated broad therapeutic activity and disease reversal across a range of autoimmune disorders including diabetes, multiple sclerosis, ALD and IBD while consistently preserving immunocompetence to resist viral, microbial, and tumor challenges.

About Parvus Therapeutics Inc.
Parvus Therapeutics Inc. is a privately-held biopharmaceutical company engaged in the development and commercialization of Navacim therapeutics targeting autoimmune diseases. Navacims were discovered by Pere Santamaria, M.D., Ph.D. Chief Scientific Officer and Founder of Parvus, Julia McFarlane/Diabetes Canada Professor of the Cumming School of Medicine at the University of Calgary.
