Orexo Ab Stock Price, News & Analysis

Orexo AB (OTCQX: ORXOY) is a Swedish pharmaceutical company that focuses on developing improved pharmaceuticals based on proprietary formulation technologies that address large medical needs. The company is listed on Nasdaq Stockholm's main list and its shares are also available to U.S. investors as American Depositary Receipts (ADRs) on the OTCQX market under the symbol ORXOY.

According to company disclosures, Orexo has around 30 years of experience in pharmaceutical development. A central part of its business is the use of proprietary formulation technologies to enhance the properties of new or existing drugs. On the U.S. market, Orexo provides treatment solutions for patients suffering from opioid use disorder and adjacent diseases. In addition, products targeting other therapeutic areas are developed and commercialized worldwide together with partners.

AmorphOX drug delivery platform

A key technology for Orexo is its proprietary drug delivery platform AmorphOX. Company materials describe AmorphOX as a powder made up of particles built from a combination of a drug, carrier materials and, optionally, other ingredients. These particles form an amorphous composite that is designed to provide chemical and physical stability and rapid dissolution. The technology has been used with a broad scope of active ingredients and has been validated in several human clinical studies, where it has shown rapid and extensive drug exposure.

Orexo uses AmorphOX to develop powder-based formulations that can enable alternative routes of administration and improve stability. The platform has been applied to small molecules, peptides and larger biomolecules such as vaccines, according to company announcements. The strategy described in recent news is to broaden the use of AmorphOX and to establish collaborations that demonstrate its potential in multiple therapeutic areas.

Focus on opioid use disorder and rescue medications

In its public communications, Orexo states that on the U.S. market it provides treatment solutions for patients with opioid use disorder. The company also develops rescue medications for acute conditions. One example is OX124, described as a high-dose naloxone rescue medication for opioid overdose. Interim reports note that OX124 is being prepared as a second medication on the U.S. market and that regulatory interactions with the U.S. Food and Drug Administration (FDA) have included requests for additional technical data and human factors studies.

Another development project is OX640, a nasal rescue medication with powder-based epinephrine for the treatment of severe allergic reactions, including anaphylaxis. OX640 is based on the AmorphOX platform and is designed as an intranasal product. Company news reports describe phase 1 and subsequent clinical studies evaluating pharmacokinetic and pharmacodynamic effects, including comparisons with intramuscular epinephrine injections and assessments in subjects with and without allergic rhinitis.

Intranasal formulations and large molecules

Recent Orexo announcements highlight the use of AmorphOX for intranasal delivery. In preclinical in-vivo work, the company developed powder-based intranasal formulations of semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. These formulations were compared with an oral tablet and a subcutaneous injectable form. The company reports that certain AmorphOX-based intranasal formulations achieved higher plasma concentrations and bioavailability than the oral tablet, while remaining below injectable levels, and showed lower variability in plasma concentration.

Based on these data, Orexo states that its strategy for AmorphOX has been updated to prioritize larger molecules such as peptides, proteins and vaccines. The company emphasizes the ability of the powder-based intranasal formulation technology to develop formulations for large molecules that are well absorbed through mucosal membranes, and notes that this may support needle-free delivery and potentially more convenient dosing regimens compared with some existing routes of administration.

Collaboration on nasal powder vaccines

Orexo has also entered into collaborations to extend the reach of its technology. A disclosed collaboration with Abera Bioscience aims to develop mucosal vaccines by combining Orexo's AmorphOX powder-based drug delivery technology with Abera's vaccine platform BERA. As a first step, the partners have focused on powder-based intranasal vaccine candidates, including an influenza vaccine candidate.

In a proof-of-concept study in rats, Orexo reports that an intranasal influenza vaccine candidate formulated either as a liquid nasal solution or as an AmorphOX-based intranasal powder induced strong systemic antibody responses in serum (IgG) and local responses in the nose and lungs (IgA), with no difference in immune response between the two formulations. Company communications highlight the potential of powder formulations to support thermostable vaccines that may not require cold chain logistics.

Clinical development of OX640

Orexo has conducted several clinical studies of OX640. A phase 1 study (OX640-001) in healthy volunteers evaluated absorption and effects on blood pressure and heart rate compared with an intramuscular epinephrine auto-injector. A later study (OX640-002) was designed as a four-period cross-over study in subjects with seasonal allergic rhinitis. It assessed epinephrine plasma levels, blood pressure and heart rate after administration of different OX640 doses and intramuscular epinephrine, including a period in which OX640 was given after induction of acute allergic rhinitis symptoms.

Topline data reported by Orexo indicate that OX640 treatments achieved mean epinephrine plasma levels associated with clinical efficacy more rapidly than the intramuscular reference product, with dose-dependent exposure. Absorption under allergic rhinitis conditions was described as significantly faster than under normal conditions, and OX640 formulations typically produced more pronounced increases in blood pressure and heart rate than the intramuscular injection. The company states that systemic safety findings were in line with known epinephrine pharmacology and that local effects were transient and tolerated.

Business model and partnerships

Across its communications, Orexo describes a business model that combines proprietary technology development with commercialization and partnerships. In the U.S., the company provides treatment solutions for opioid use disorder and related conditions. For products in other therapeutic areas, Orexo indicates that they are developed and commercialized worldwide with leading partners. Collaborations, such as the one with Abera Bioscience, are presented as a way to leverage the scalability of the AmorphOX platform and to demonstrate its applicability to different types of active ingredients.

Interim reports also reference a U.S. Commercial segment and products such as Zubsolv and Abstral in the context of revenues and royalties. The company reports that it continues to work on business development to attract new companies to use AmorphOX and notes interest in projects such as OX640.

Corporate profile and listing

Orexo describes itself as a Swedish pharmaceutical company with nearly or around three decades of experience, depending on the specific disclosure. Its operations are presented as focused on developing improved pharmaceuticals that meet large medical needs, with particular emphasis on formulation technologies. The company is listed on Nasdaq Stockholm's main list and its ADRs trade on the OTCQX market in the United States under the ticker ORXOY.

Public reports from Orexo include regular interim financial updates, information on clinical and preclinical studies, collaboration agreements, and corporate governance matters such as the composition of the nomination committee for the annual general meeting. These communications provide investors and other stakeholders with insight into the company's development pipeline, technology platform, and commercial activities.
