This review first examined global health governance (GHG) for PPPR, identifying its core-satellite structure. Key GHG functions include rule-setting, resource mobilization, medical countermeasures (MCMs) supply, surveillance and data/pathogen sharing with rapid response, and One Health. Major gaps exist in global collaboration, enforcement of the International Health Regulations (IHR), and the World Health Organization's (WHO) capacity. The most urgent issue is pathogen access and benefit-sharing (PABS). Second, the PPPR capacity across world regions were assessed using two public datasets: eSPAR and GHS Index. Sub-Saharan Africa requires urgent support to strengthen most PPPR aspects, while epidemiological and laboratory surveillance, infection prevention and control (IPC), and regulatory functions need improvement in low- and middle-income countries (LMICs) in various regions outside Europe. Japan, with its strong PPPR capacity, is well-positioned to assist. Lastly, the review explored the link between PPPR and health systems strengthening (HSS). PPPR must be firmly integrated into HSS to ensure resilience, equity, inclusiveness, continuity of care, and sustainability. Core health system components - service delivery, workforce, health information systems, MCMs access, and governance - along with communication and trust-building, effectively contribute to PPPR. However, pandemic exceptionalism and the over-securitization of PPPR and health security may hinder coordination. The enhanced GHG for PPPR, led by the empowered WHO, should effectively facilitate and coordinate technical assistance to LMICs to strengthen their PPPR capacities and promote PPPR-HSS integration by bringing together the often-divided health security and HSS communities.</p>","PeriodicalId":12556,"journal":{"name":"Global health & medicine","volume":"7 2","pages":"112-126"},"PeriodicalIF":1.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12047038/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144016784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SAG-524 exerts its effect by destabilizing HBV RNA by shortening the poly(A) tail, which leads to a significant reduction of both pgRNA and PreS/S mRNA. This destabilization seems to be specific for HBV RNA molecules. The mechanism involves the recruitment of PAPD5/7 by ZCCHC14 to the HBV RNA, where guanine is incorporated into the poly(A) tail to protect against degradation. SAG-524 disrupts this process by directly targeting PAPD5, thus destabilizing HBV RNA. In preclinical trials, oral administration of SAG-524 reduced serum HBsAg levels in HBV-infected PXB mice. When combined with NAs or capsid assembly modulators (CAMs), significant reductions in HBsAg, HBV DNA, and intrahepatic covalently closed circular DNA were observed. Safety studies conducted over 13 weeks in mice and monkeys revealed no significant toxicity, demonstrating the drug demonstrated a favorable safety profile. In conclusion, the novel mechanism of action, high oral bioavailability, and strong suppression of HBsAg make SAG-524 a promising candidate for future therapeutic use. The potential for combination therapy with NAs or CAMs underscores its capacity to contribute to achieving a functional cure for chronic HBV infection.</p>","PeriodicalId":12556,"journal":{"name":"Global health & medicine","volume":"7 1","pages":"64-66"},"PeriodicalIF":1.9,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11866905/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143541144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
