First SOF-SKN Dose Cohort Cleared, Trial Progresses to Higher Doses

Early Success in Safety Assessment

Noxopharm Limited, an Australian clinical-stage biotech company, has announced a significant milestone in its HERACLES clinical trial with the successful completion of the first cohort receiving the lowest dose of SOF-SKN™, a novel drug candidate aimed at treating autoimmune diseases. The safety steering committee overseeing the trial has confirmed that this initial dose was safe and well tolerated, with no clinically relevant adverse effects reported.

This positive safety profile is crucial in early drug development, as regulatory authorities require stringent evidence to ensure patient safety before advancing to higher doses or larger trials. Approximately 30% of new drugs fail due to toxicity concerns, so clearing this initial hurdle is a promising sign for SOF-SKN™’s future.

Next Steps in Dose Escalation

With the green light from the safety committee, the HERACLES trial will now proceed to enroll the second cohort of participants who will receive a higher dose of SOF-SKN™. The trial protocol involves four cohorts, each with four participants, receiving incrementally increased doses to carefully evaluate safety and tolerability at each level. This stepwise approach allows for detailed monitoring through physical exams, blood tests, skin assessments, and other diagnostic measures over approximately two weeks per cohort.

Strategic Focus on Autoimmune Diseases

SOF-SKN™ is being developed initially for cutaneous lupus erythematosus (CLE), a chronic autoimmune skin condition affecting millions worldwide. The global market for CLE treatments exceeds US$3.3 billion and is expected to grow substantially. Beyond CLE, the underlying Sofra™ technology platform holds potential for a broader range of autoimmune and inflammatory diseases, including psoriasis, dermatomyositis, rheumatoid arthritis, type 1 diabetes, and even neurodegenerative conditions linked to immune dysregulation.

Conducting the trial in Australia not only taps into local expertise in lupus research and early-phase clinical trials but also allows Noxopharm to benefit from federal research and development tax incentives, supporting the company’s innovation pipeline.

Looking Ahead

While these early safety results are encouraging, the HERACLES trial remains in its initial stages, focusing primarily on establishing a safe dosing range. Efficacy data and broader clinical outcomes will follow in subsequent phases. The biotech sector and investors will be watching closely as Noxopharm advances through the dose escalation steps, potentially positioning SOF-SKN™ as a novel therapeutic option in a competitive and growing autoimmune disease market.
