   1.                                                   You state that you
establish the volatility rate used to determine the fair value of your
                                                        equity awards based on
the historical volatility of a group of similar companies in the
                                                        biotechnology industry
that are publicly traded. As the company has been a public
                                                        company since 2018,
please tell us why you believe this methodology is appropriate. In
                                                        this regard, tell us
what your estimated expected volatility would have been for each year
                                                        presented if you only
considered the company   s expected and historical volatility rates
                                                        and not the volatility
rates of your peers. Further, explain why you did not use these
                                                        company only rates in
estimating the fair value of your stock options for those respective
                                                        periods, and tell us
when you no longer intend to consider the volatility rates of publicly

         traded peers in this estimate. We refer you to ASC718-10-55-37, and
question 6 in SAB
         Topic 14.D.1. Lastly, please explain why the volatility used to
estimate your stock option
         awards in 2021, 86%, is different from the volatility used for your
ESPP volatility
         estimate, 91%. Direct us to disclosure included in your quarterly
report for the period
         ended September 30, 2022 where the assumptions used to determine the
fair value of your
         ESPP awards is discussed.

2.       Please provide us with a detailed analysis supporting your conclusion
that Radionetics
         does not have sufficient equity at risk to finance its activities
without additional
         subordinated financial support and therefore meets the definition of a
variable interest
         entity (VIE). Address the following in your response:

                Explain how you determined that Radionetics would not be able
to obtain other non-
              subordinated sources of financing, if necessary.
                Address your considerations of both quantitative and
qualitative factors, to the extent
              considered in determining the sufficiency of equity at risk,
using the guidance in ASC
              810-10-25-45 through 810-10-25-47.
                Ensure that your analysis focuses on whether Radionetics was
structured, by design,
              not to have sufficient equity at risk. In this regard, ASC
810-10-15-14 states that the
              phrase "by design" refers to legal entities that meet the
conditions in this paragraph
              because of the way they are structured.
                ASC 810-10-25-47 states that the design of the legal entity and
the apparent
              intentions of the parties that created the legal entity are
important qualitative
              considerations. Clarify for us whether the formation of
Radionetics was essentially
              the spin-off of your nonpeptide platform into a separate entity
funded with $30
              million in private financing provided by 5AM Ventures and Frazier
Healthcare
              Partners and how this factored into your analysis.

Research and development expenses, page 75

3.       We note the significant increase in your research and development
expenses in fiscal 2021
         and that you have multiple programs/products in varying stages of
development and
         clinical testing, and note that you expect your research and
development expenses to
         increase. Please confirm that you will revise future filings to
provide more details about
         your research and development expenses for each period presented,
including but not
         limited to by product/program, internal versus external, as well as by
the nature of the
         expenses. For example, in discussing the specific reasons for
significant changes
         in research and development expenses, quantify the change by each
product candidate for
         which significant investments were made during the periods. Refer to
Item 303(b) of
         Regulation S-K. To the extent that you do not track expenses by
product candidate, please
         disclose as such.
