Proceeds support first-in-class development program through key clinical and regulatory milestones, including completion of the Phase 2 STAR trial in HIE, top-line data readout, and End-of-Phase 2 meeting with the FDA

Company has raised more than $150 million since its formation

NORFOLK, Va.–(BUSINESS WIRE)–ReAlta Life Sciences Inc. (“ReAlta” or the “Company”), a clinical-stage biopharmaceutical company focused on safely targeting neutrophils and central components of the complement system to potentially revolutionize the treatment of inflammatory disorders, today announced the closing of an oversubscribed $40 million financing. This brings the total capital raised to date to more than $150 million.

The Company will use the proceeds to advance pegtarazimod through key clinical and regulatory milestones as the first potential treatment for Hypoxic Ischemic Encephalopathy (HIE.) Upcoming milestones for this first-in-class program include completion of the Phase 2 STAR trial in HIE (currently underway at 13 sites across the United States), the study’s top-line data readout, and an End-of-Phase 2 meeting with the FDA.

Howard Berman, Ph.D., the Company’s Chief Executive Officer, said, “Every year, thousands of newborns suffer devastating brain injury from HIE with no approved drug therapy to offer them. Rarely in a career does one have the opportunity to work on a program with this level of both scientific rigor and human urgency. This financing reflects strong conviction in pegtarazimod’s potential to change that reality. By targeting both complement activation and neutrophil-driven inflammation, which are the upstream drivers of brain injury in HIE, pegtarazimod represents a fundamentally different and potentially transformative approach. We believe that we are well-positioned to deliver on the key milestones ahead.”

Kia Motesharei, Ph.D., ReAlta’s President and Chief Operating Officer, added, “This financing allows us to execute against key value-inflection points with a disciplined and focused strategy. We are committed to deploying this capital efficiently to generate meaningful clinical and strategic milestones. Our team is creating a new category of medicine for HIE patients where currently no drug therapeutic option is available. The financing enables us to accelerate our work toward realizing that vision. The goal here is not to provide incremental improvement, but to fundamentally change how doctors treat newborn babies who develop HIE.”

About ReAlta Life Sciences

ReAlta Life Sciences is a clinical-stage biopharmaceutical company redefining the treatment possibilities for patients with devastating and historically untreatable inflammation-driven diseases by developing first-in-class tailored peptides designed to achieve life-changing outcomes with unprecedented safety. The company’s lead candidate, pegtarazimod (RLS-0071), is a next-generation dual-targeting intervention that represents a solution that rebalances the body’s inflammatory response and prevents tissue damage by selectively blocking both complement- and neutrophil-mediated pathways at the outset, disrupting inflammation at the core.

About RLS-0071 (pegtarazimod)

Pegtarazimod is a 15-amino-acid peptide that uniquely targets both humoral and cellular inflammation and is the Company’s lead therapeutic candidate. The peptide works by inhibiting complement activation at C1, as well as myeloperoxidase activity and neutrophil extracellular trap (NET) formation—key mechanisms implicated in the inflammatory cascade underlying a broad range of diseases driven by dysregulated neutrophils and complement activity. Pegtarazimod was derived from a mechanistic discovery of the human astrovirus HAstV-1, a virus known to cause non-inflammatory gastroenteritis, which provided a novel scaffold for innate immune modulation. Across multiple clinical studies in healthy volunteers and patients with life-threatening inflammatory conditions, pegtarazimod has demonstrated a favorable tolerability profile and encouraging clinical signals, supporting its development in acute inflammatory diseases with significant unmet medical need. Pegtarazimod has received FDA Orphan Drug and Fast Track Designations for Hypoxic Ischemic Encephalopathy (HIE) and EMA Orphan Drug Designation for HIE.

About Hypoxic Ischemic Encephalopathy (HIE)

Hypoxic Ischemic Encephalopathy (HIE) is a serious and often devastating form of neonatal brain injury caused by a lack of oxygen and blood flow to the brain during or around the time of birth. HIE affects thousands of newborns each year in the United States and globally and remains a leading cause of neonatal mortality and long-term neurological disability, including cerebral palsy, epilepsy, and cognitive impairment. Therapeutic hypothermia is currently the standard of care and has been shown to provide modest benefit in some infants; however, there are currently no approved drug therapies that directly target the underlying inflammatory injury that contributes to brain damage following hypoxic ischemic events. As a result, there remains a significant unmet medical need and a potentially multi-billion-dollar global market opportunity for therapies that can meaningfully improve neurological outcomes in affected infants.

About the STAR Trial

The STAR trial (NCT05778188) is a two-stage, randomized, double-blind, placebo-controlled study currently enrolling patients across 13 NICUs in the United States, evaluating RLS-0071 (pegtarazimod) in newborns with moderate or severe HIE undergoing therapeutic hypothermia.
