Onconetix Inc.

Company Overview

Business Model: Onconetix, Inc. is a commercial stage biotechnology company focused on men’s health and oncology. Its primary asset is Proclarix, an in vitro diagnostic test for prostate cancer, approved for sale in the European Union under the In Vitro Diagnostic Regulation (IVDR). Proclarix is a protein-based blood test that integrates thrombospondin 1 (THBS1) and cathepsin D (CTSD) levels, patient age, and total/free PSA to generate a proprietary Proclarix Risk Score. It is validated for men with elevated total PSA (2.0 to 10.0 ng/mL), normal DRE, and elevated prostate volume (≥35 mL), and is anticipated to be marketed in the U.S. as a lab developed test through an exclusive license agreement with Laboratory Corporation of America. The company previously owned ENTADFI, an FDA-approved pill for benign prostatic hyperplasia (BPH), but commercialization has been abandoned due to resource constraints, and the company is seeking a potential sale of these assets.

Market Position: Proclarix is included in European Association of Urology (EAU) and 2023 American Urological Association (AUA)/Society of Urologic Oncology (SUO) clinical practice guidelines, demonstrating clinical recognition. Clinical studies indicate Proclarix can reduce unneeded biopsies by approximately 43%. The company operates in the intensely competitive molecular diagnostics field, which was valued at $101 billion worldwide in 2024. Proclarix differentiates itself by being blood-based, immunoassay-based, easy to automate, providing objective results, and utilizing genetics-guided biomarker discovery.

Recent Strategic Developments:

• Acquisition of Proteomedix: On December 15, 2023, Onconetix, Inc. acquired 100% of Proteomedix, the developer of Proclarix, for a total acquisition-date fair value of consideration transferred of $65.1 million.
• U.S. Commercialization Partnership: On March 23, 2023, Proteomedix entered an exclusive license agreement with Laboratory Corporation of America for Proclarix in the U.S. market, including an initial license fee in the mid-six figures, 5-10% royalties on net sales, and up to $2.5 million in milestone payments. Laboratory Corporation of America is responsible for U.S. R&D and commercialization costs.
• Abandonment of ENTADFI: Commercialization of ENTADFI was abandoned due to resource constraints and indebtedness, with assets fully impaired at June 30, 2024.
• Potential Business Combination: On April 1, 2025, Onconetix, Inc. signed a Non-Binding Letter of Intent for a potential business combination with Ocuvex Therapeutics, Inc., where pre-closing Ocuvex Therapeutics, Inc. equity holders would own approximately 90% of the combined company.

Geographic Footprint: Onconetix, Inc. has commercial availability of Proclarix in Europe, with pilot laboratories established in Switzerland, Germany, Italy, and the United Kingdom. The U.S. market is targeted through the exclusive license agreement with Laboratory Corporation of America.
