It discloses that among subjects with more than one year of long-term dosing who transitioned to the same dosing regimen as the WAKABA trial (1 mg\/kg subcutaneous once weekly), no new safety concerns were observed up to three months after transition. Currently, 11 of 12 subjects are participating in the trial, and 7 subjects remain ongoing. Follow-up results for the first subject who transitioned have been reported. The company states there is no impact on full-year results for the fiscal year ending March 2027.\n\n### Impact on Investors and Outlook\nAccumulation of safety data from the long-term dosing trial and the WAKABA trial could complement safety information and potentially expand treatment options. However, the current financial impact is unknown, and future trial progress and approval status could still affect performance.","jir_financial_highlights":"Impact Scope: Unknown (Unknown)\nFX Impact: Unknown (Unknown)","jir_category":"","jir_hashtags":"#Ribomic, #NoUpdateSafetyInformation","jir_key_figures":"Number of subjects evaluated for safety: Unknown (document notes 11 of 12 subjects are participating)\nSafety concerns at three months after transition: None\nTransition to WAKABA trial dosing regimen: First subject reached three months after transition","jir_meta_title":"Ribomic Inc. \u2014 Safety Transition Report for Domestic Long-Term Dosing Trial | Impact on FY2027 Unclear","jir_meta_description":"Safety transition report for Ribomic's domestic Phase II long-term dosing trial.
