Long-Acting Formulations of Telaprevir

United States Patent 10,052,314, assigned to the Board of Regents of the University of Wisconsin System (an invention development partner for AbbVie), describes the development of long-acting formulations of telaprevir, a protease inhibitor used in the treatment of hepatitis C infection. The patent emphasizes the importance of sustained viral suppression in managing the disease, which underscores the need for effective treatments that maintain therapeutic levels of telaprevir over prolonged periods.

Telaprevir Background and Limitations

Telaprevir was initially approved in 2011 as part of combination therapies for chronic hepatitis C infection. However, its short half-life necessitated frequent dosing, and its use was ultimately withdrawn due to concerns regarding its metabolic interaction with ritonavir-boosted protease inhibitors. Attempts to reformulate the compound led to slower aqueous solubility, making it difficult to achieve effective doses while minimizing side effects.

Patent Scope and Claims

The patent describes a novel approach to overcoming existing limitations through the development of spray-dried telaprevir particles with optimized formulations. The formulations exploit telaprevir's ability to form a semi-solid state of high solubility, which preserves its stability and maintains consistent therapeutics levels after administration. The inventive strategy is designed to augment existing treatments for hepatitis C by providing predictable, long-term efficacy.

Key Aspects of the Patent

  • Descriptions of methods for spray-drying telaprevir in aqueous surfactant solutions to produce stabilized formulations
  • Compositions of the inhaled formulation to deliver therapeutic amounts of telaprevir without side effects
  • Efficacy of sub-chronic and chronic efficacy models assessing the functionality of formulations without liver damage and to assess efficacy

This development aligns with ongoing research into tackling hepatitis C.
