Over the past few years, an enormous amount of research has investigated the viral infection and replication processes following the first SARS-CoV-2 case. With this knowledge, many drugs have been explicitly created to inhibit viral replication or decrease the severity of the immune response. Additionally, scientists have utilized decades of research and techniques to expedite SARS-CoV-2 vaccine development. SARS-CoV-2, a positive-strand RNA virus, belongs to the Sarbecovirus subgroup of Betacoronaviruses. Its emergence is not unique; previous outbreaks like SARS and MERS have shaped our understanding of coronavirus-related diseases. Molecular clock analysis suggests that the ancestor of all current coronaviruses existed over 10,000 years ago, with subsequent evolution occurring around 3300-2400 BC.

This phase 2b multicenter basket trial proposes a novel approach to evaluate a common antifibrotic therapy across these diverse but pathophysiologically related conditions. The trial employs a two-stage Simon design to address the statistical challenges posed by small patient populations, allowing the inclusion of ultra-rare diseases while maintaining analytical rigor.
