FDA Grants Orphan Drug Status to Unravel Biosciences' Vorinostat for Rett Syndrome

Unravel Biosciences, Inc., a company leveraging AI for drug development, has made significant strides in the treatment of Rett Syndrome with its drug candidate, vorinostat (RVL-001). The United States Food and Drug Administration (FDA) recently granted Orphan Drug Designation to RVL-001, a milestone that underscores the company's commitment to addressing rare diseases.

Rett Syndrome is a rare neurogenetic disorder that typically manifests in early childhood, leading to severe cognitive, motor, and autonomic dysfunctions. Affecting approximately one in 10,000 female births globally, the disorder represents a significant unmet medical need, with limited treatment options currently available.

The development of RVL-001 has been facilitated by Unravel’s BioNAV™ platform, an advanced drug discovery system that integrates AI with biological computation to identify promising therapeutics for complex diseases. Over the last 18 months, Unravel has accelerated its efforts to bring RVL-001 into clinical testing. This rapid progress was marked by positive feedback from a pre-IND meeting with the FDA, the initiation of clinical trial material manufacturing, and the commencement of a multicenter clinical study in collaboration with Vanderbilt University in the United States.

Richard Novak, Ph.D., Co-Founder and CEO of Unravel, highlighted the importance of the FDA’s Orphan Drug Designation. He stated, "This designation validates our team's dedication to developing new treatments for patients with rare diseases. Our recent collaborations and upcoming studies illustrate the speed and efficiency with which Unravel can prototype and evaluate new drugs."

Unravel is actively pursuing clinical studies for RVL-001 in both the United States and Colombia. The U.S. study is a landmark collaboration with Vanderbilt University, while the Colombian study aims to provide additional proof of concept for RVL-001’s efficacy in treating Rett Syndrome.

In addition to RVL-001, Unravel is also developing RVL-002, a novel molecule designed to target Rett Syndrome. This initiative is part of the company’s broader strategy to address complex diseases through innovative therapeutic solutions.

Unravel Biosciences operates as a rapid prototyping therapeutics company, combining AI-driven systems biology with swift in vivo screening and clinical validation. The company’s proprietary BioNAV™ platform merges target and drug discovery, preclinical screening, and patient stratification to identify effective treatments for intricate diseases. This platform has led to the initiation of four clinical trials in 2024, including RVL-002, which targets mitochondrial metabolism, and RVL-027, designed to treat dystonias through a novel mechanism.

Unravel’s rareSHIFT™ program further enhances its capabilities by offering platform access to foundation and biotech partners, aiming to accelerate and clinically de-risk the development of new therapeutics.

As Unravel continues to innovate and push the boundaries of drug development, its work on RVL-001 and other candidates holds promise for providing much-needed treatments for patients suffering from rare and complex diseases like Rett Syndrome.
