  • Full-Time

Parvus Therapeutics Inc.

Parvus Therapeutics Inc. is a privately held biopharmaceutical company developing Navacims™, a platform technology based on foundational research published in 2016 (Nature 530:434), to treat autoimmune diseases. Parvus’ mission is to shift the treatment paradigm toward Navacim™-directed immune regulation, avoiding non-specific immune suppression associated with current therapies. Parvus’ innovative approach has the potential to benefit millions of patients suffering from debilitating autoimmune diseases and other chronic inflammatory conditions. Parvus is advancing a pipeline of proprietary drug candidates for multiple autoimmune indications through preclinical development and into the clinic. Parvus’ leadership team is experienced in successful drug discovery, development, manufacturing, regulatory approval, and commercialization.

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 programs effector T cells to differentiate 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.

The Position

We are seeking a Senior Research Associate to support the Parvus technology platform.
