Sterotherapeutics Begins Phase 2 Trial for Cushing's Syndrome

Sterotherapeutics, a prominent biopharmaceutical company based in Doylestown, Pennsylvania, has announced the commencement of a Phase 2 clinical trial for ST-002, a new drug candidate targeting Cushing’s Syndrome. This rare endocrine disorder is characterized by an excess of cortisol, which can result in severe health issues such as diabetes, hypertension, osteoporosis, and increased mortality if not properly treated. Currently, there are limited treatment options available for this condition, creating a significant need for innovative therapies.

The official launch of the trial was marked by an Investigator Meeting in Athens, Greece, on February 24, 2025. This gathering of clinical investigators, research coordinators, and stakeholders focused on discussing the objectives and protocols of the trial, as well as refining best practices to ensure the trial's success.

Dr. Manohar Katakam, CEO of Sterotherapeutics, expressed enthusiasm about this advancement in their clinical development efforts. Highlighting the importance of collaboration, Dr. Katakam pointed out that working closely with expert investigators is crucial for maintaining high scientific standards and ensuring patient safety throughout the trial. The primary goal of the Phase 2 trial is to assess the safety, efficacy, and tolerability of ST-002 in patients with Cushing’s Syndrome.

Dr. Constantine Stratakis, Executive Medical Director of Sterotherapeutics, emphasized the importance of the Investigator Meeting in fine-tuning the trial’s processes. He expressed optimism about engaging with the investigators to drive forward this promising treatment option. The trial will take place across various clinical sites throughout Europe, enhancing its scope and potential impact.

Recognizing the urgent need for new treatments for Cushing’s Syndrome, the U.S. Food and Drug Administration (FDA) has granted ST-002 an orphan drug designation. This status is given to drugs that treat rare diseases, and it offers several regulatory incentives to support the development of new therapies. These incentives include assistance in the drug development process, tax credits for clinical research costs, exemptions from certain FDA fees, and seven years of post-approval marketing exclusivity.

Sterotherapeutics is a clinical-stage company that focuses on developing new therapeutics for rare diseases with high unmet needs. In addition to ST-002, the company is also advancing ST-003, targeting primary sclerosing cholangitis. Both ST-002 and ST-003 have demonstrated effectiveness in previous studies and have favorable safety profiles. The orphan drug designation by the FDA underscores the potential of these therapies to address significant gaps in treatment for rare conditions.

As Sterotherapeutics continues to push boundaries in biopharmaceutical research, the launch of the Phase 2 trial for ST-002 represents a pivotal step in their mission to develop transformative treatments for patients with limited options. By fostering collaboration and leveraging regulatory incentives, the company aims to bring new hope to those affected by Cushing’s Syndrome and other rare diseases.
