Jasper Therapeutics (JSPR) Stock Price, News & Analysis

Company Overview

Jasper Therapeutics, Inc. is a clinical-stage biotechnology company dedicated to discovering and developing novel therapies that target the complement system for the prevention and treatment of rare diseases, organ transplant rejection and certain inflammatory conditions. Its lead product candidate, nomacopan, is an investigational, small‐protein dual inhibitor of complement component C5 and leukotriene B4, designed to address the underlying drivers of tissue damage in disorders such as paroxysmal nocturnal hemoglobinuria (PNH), bullous pemphigoid and cutaneous acute graft-versus-host disease. In addition to nomacopan, Jasper’s pipeline includes earlier-stage complement inhibitors aimed at improving transplant outcomes in kidney and other solid-organ recipients.

Founded in 2015 as a spin-out from the University of Pennsylvania and the University of Washington, Jasper Therapeutics completed its initial public offering on the Nasdaq in 2018. The company has established strategic collaborations and license agreements to support global development and commercialization, leveraging partnerships with leading pharmaceutical firms to expand the reach of its complement‐modulating technology. Headquartered in Plymouth, Minnesota, Jasper conducts multi‐center clinical trials across North America, Europe and Australia.

Jasper’s management team brings deep expertise in immunology, rare disease development and regulatory strategy. The company is led by a seasoned executive team and board of directors with decades of experience guiding small and mid‐sized biopharmaceutical enterprises through late‐stage clinical trials and toward potential commercialization. This leadership collective underscores Jasper’s commitment to advancing its pipeline and delivering transformative therapies for patients with high‐unmet medical needs.
