Hannah Adeoye's questions to Surrozen, Inc./DE (SRZN) leadership • Q4 2022
Question
Hannah Adeoye from JPMorgan Chase & Co. asked about the half-life of SZN-1326 and the expected dosing regimen or frequency for a future multiple ascending dose study. She sought to understand what data provides comfort that the previously observed adverse events won't recur over longer dosing intervals.
Answer
CEO Craig Parker stated that the half-life of SZN-1326 is approximately 5 days based on primate studies. He explained that the biological effects could be longer-lasting than the PK half-life suggests, potentially allowing for an every-other-week or even less frequent dosing regimen. Parker noted that the final dosing frequency for the Phase Ib study has not yet been determined and will depend on further human PK data.
