4.       We note your revisions in response to our prior comment 9 and reissue
in part. We note
         that you reference "clinical studies" in this section, but the only
clinical study you identify
         is the ACCRUE study. Please clarify whether you have conducted any
other clinical
         studies related to your QT scan and provide a description of each
additional clinical study.
         Please also provide more detail about the ACCRUE study, including its
purpose and
         scope, the study design, the amount of participants, the primary and
secondary endpoints,
         whether it was powered to show statistical significance

5.       We note your response to our prior comment 11 and reissue the comment.
Please
         substantially expand your disclosure of each of the nine potential
business combination
         targets that the GigCapital5 management team and/or GigManagement
considered. For
         example, without limitation, disclose for each of the nine potential
targets the industry of
         the target's business, proposed valuations, who identified the target,
who participated in
         negotiations with the target, when the target was identified and who
initiated discussions
         with the target. To the extent that any preliminary negotiations
occurred or preliminary
         proposals were submitted for any of the nine potential targets, please
disclose all material
         proposal terms, including the subject and nature of any preliminary
negotiations and any
         terms related transaction structure, valuation, and equity split
distribution. We note, for
         example, your statement that discussions for some targets were
terminated because "the
         parties were either unable to agree upon potential terms for a
transaction, [or] GigCapital5
         decided to move away from the process due to further information
collected." Please
         elaborate. Additionally, please disclose for each of the nine
potential targets when
         discussions ended and the specific reasons why GigCapital5 did not
continue to pursue a
         business combination with the target.

6.     We note your revisions in response to our prior comment 12 and reissue
in part. We note
       your statement that the proposed valuation of $151 million took into
account "the state of
       valuations of both private and public companies throughout 2022, and in
particular in the
       second half of the year which saw a decrease in valuation from the
period considered in
       the comparable company analysis." Please revise to disclose the
underlying assumptions
