10 mg / 2 mL = 5 mg/mL 2 mg = 2,000 mcg 2,000 mcg / 5,000 mcg per mL = 0.4 mL = 40 U-100 units Retatrutide 5 mg vial with 2 mL example A 5 mg retatrutide vial mixed with 2 mL gives 2.5 mg/mL, or 2,500 mcg/mL half the concentration of the 10 mg example
Expected Corrective and Preventive Actions (CAPA) Remove non-regulatory barriers from follow-up procedures and ensure follow-up requirements are fully aligned with FDA expectations Define prompt investigation as a controlled process step with clear requirements for timing, documentation, follow-up attempts, and escalation Implement a risk-based follow-up model for serious cases, especially those involving death, suicidality, or other medically significant outcomes Establish formal oversight of vendor-executed follow-up activities , including review of documentation quality, timeliness, and completeness Perform a retrospective assessment of serious cases to confirm whether follow-up was timely, documented, and sufficient Introduce effectiveness checks demonstrating that revised procedures and oversight controls consistently support compliant follow-up in the future Practical Remediation Horizon FDA did not lay out a formal phased timeline in the Warning Letter, but the remediation logic points to a sequence that would typically need to include the following: Immediate Actions (03 Months) Stop using procedures that conflict with FDA PADE requirements Reconcile and submit all potentially missed 15-day Alert reports Implement interim review controls for case validity, patient identifier capture, and medical-review aging Begin independent assessment of pharmacovigilance procedures, vendor interfaces, and deviation/CAPA systems Short-Term Actions (36 Months) Finalize revised SOPs, work instructions, training materials, and SDEAs Complete retrospective reviews of affected cases and pharmacovigilance-related deviations Implement formal daily aging review and escalation controls across workflow states Define vendor quality oversight activities, including audits, KPIs, training checks, and source-data verification Long-Term Actions (612 Months) Demonstrate CAPA effectiveness through measurable compliance outcomes Establish governance forums for recurring review of ADE timeliness, validity errors, follow-up quality, and vendor performance Complete portfolio-wide impact assessment and close any residual systemic gaps Strengthen management review so serious pharmacovigilance deviations are escalated and challenged before they recur Conclusion This Warning Letter is fundamentally about pharmacovigilance system design
