ArkBio’s Ziresovir Recognized by WHO for Pediatric RSV Prevention
GENEVA, SWITZERLAND – July 16, 2025 – ArkBio, a leading biopharmaceutical company dedicated to developing innovative solutions for unmet medical needs, announced today that its promising investigational drug, Ziresovir, has been included in the World Health Organization’s (WHO) Pediatric Respiratory Syncytial Virus (RSV) Drug Priority List. This significant recognition highlights the potential of Ziresovir to address the critical global health challenge posed by RSV in infants and young children.
Respiratory Syncytial Virus (RSV) is a common respiratory virus that typically causes mild, cold-like symptoms. However, for infants and older adults, RSV can be severe and lead to serious complications, including bronchiolitis and pneumonia. In young children, RSV is a leading cause of lower respiratory tract infections and hospitalizations worldwide. The WHO’s commitment to prioritizing interventions for such widespread and impactful diseases underscores the urgent need for effective preventative measures and treatments.
The inclusion of Ziresovir on the WHO’s Pediatric RSV Drug Priority List signifies a crucial step in the drug’s journey towards potentially becoming a globally accessible option for pediatric RSV prevention. This designation is typically reserved for drug candidates that demonstrate significant promise in addressing a critical public health need, are supported by robust scientific data, and have the potential for broad public health impact.
ArkBio’s Ziresovir has been developed with a novel mechanism of action aimed at inhibiting RSV replication. Preclinical studies and early-stage clinical trials have indicated a favorable safety profile and demonstrated encouraging efficacy in preventing RSV infection. The company has been diligently progressing Ziresovir through its clinical development program, with a focus on meeting the rigorous standards set by global regulatory authorities.
“We are incredibly honored by the WHO’s recognition of Ziresovir’s potential to make a meaningful difference in the lives of children affected by RSV,” said Dr. Anya Sharma, Chief Medical Officer at ArkBio. “This inclusion on the priority list is a testament to the hard work and dedication of our scientific and clinical teams, and it strengthens our resolve to bring this much-needed therapy to families worldwide. We understand the significant burden that RSV places on pediatric healthcare systems, and we are committed to advancing Ziresovir responsibly and efficiently.”
The WHO’s prioritization of Ziresovir is expected to facilitate further engagement with global health organizations, regulatory bodies, and potential manufacturing partners, with the ultimate goal of ensuring equitable access to the therapy upon its successful development and approval. ArkBio remains committed to collaborative efforts to address the global health challenges posed by RSV.
ArkBio continues to actively engage in clinical trials for Ziresovir and is focused on gathering the comprehensive data necessary for regulatory submissions. The company is optimistic about the future of Ziresovir and its potential to contribute significantly to the global fight against pediatric RSV.
