No.What are Hisun planned regulatory timelines to report this change for US VMF, for Can VMF and for CEP ?US VMF, Canadian VMF and CEP: Hisun plan to submit this change in 2022 Q1 based on the scheduled completion time (2021 Q4) of process validation.How is the change classified by Hisun for US VMF, for Canadian VMF and for CEP ?US VMF: The change is classified as Minor Changes (AR) based on current risk analysis and impact assessment, and also reference the FDA guidance Chemistry, Manufacturing, and Controls Changes to an Approved NADA or ANADA.Canadian VMF: The change is classified as Minor Changes (Annual Notification) based on current risk analysis and impact assessment, and also reference the CA guidance Post‐Notice of Compliance (NOC): Changes: Quality Document (Appendix 2, Item 2.a).CEP: The change is classified as Minor changes based on current risk analysis and impact assessment, and also reference the EDQM Guideline on Requirements for Revision/Renewal of CEP (4.II.1.1.b).Note: These are preliminary assessment, the final classification will be based on the study data of the batches manufactured with these changes.Has the manufacturing process been revalidated ? which step(s) ? Hisun plans to conduct Praziquantel process validation in 2021 Q4. This process validation will include all steps.If revalidation, was stability performed ? Stability research will be performed for the revalidation batches.Is there any impact on PSD profile obtained for non-micronized material ? Hisun will be compared PSD before and after change.Is this starting material supplier(s) captured in Elanco draft QAA and thus new alternative supplier shall be added ? No.Is this starting material supplier(s) captured in legacy Bayer QAA and thus new alternative supplier shall be added ? Yes-change of centrifuge CC-21002 EGWhen is the implementation of the change planned ?

How about the process parameters? Do they remain the same? How about the process validation? The process parameters are the same. After centrifuges installation, Hisun plans to conduct equipment PQ in 2021 Q4.Do you have any summary of the impact? Presumably, the change is forced to be implemented by safety consideration. Do you have any test results to support the conclusion? Because the size, material, working mechanism and process parameters of the equipment remain the same before and after the change, it is assessed that the change has little impact on product quality. Hisun will compare the product quality before and after the change.
