Registration Statement was subsequently filed on March&nbsp;5, 2021 (File No.&nbsp;333-253954) (the &#147;<B><I>Registration Statement</I></B>&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Because of the commercially sensitive nature of information contained herein, this submission is accompanied by the Company&#146;s request for confidential
treatment for selected portions of this letter. The Company has filed a separate letter with the Office of Freedom of Information and Privacy Act Operations in connection with the confidential treatment request, pursuant to Rule&nbsp;83 of the
Commission&#146;s Rules on Information and Requests, 17 C.F.R. &#167; 200.83. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">To assist the Staff of the Commission in its review, the Company advises
the Staff that it presently estimates that the public offering price per share pursuant to the Registration Statement for its initial public offering (&#147;<B><I>IPO</I></B>&#148;) will be between $[***] and $[***] (without giving effect to any
reverse stock split that the Company will effect prior to the offering, the &#147;<B><I>Preliminary Price Range&#148;</I></B>). The Preliminary Price Range is based in part upon the Company&#146;s prospects, prospects for the biopharmaceutical
industry, the general condition of the securities market and the recent market prices of, and demand for, publicly traded shares of generally comparable companies in the biopharmaceutical industry, as well as input received from Goldman
Sachs&nbsp;&amp; Co. LLC, SVB Leerink LLC and Piper Sandler&nbsp;&amp; Co., the lead underwriters for the IPO (the &#147;<B><I>Representatives</I></B>&#148;). The Company notes that, as is typical in IPOs, the Preliminary Price Range for the
Company&#146;s IPO was not derived using a formal determination of fair value, but was determined by discussion among the Company and the Representatives based on an assessment of the foregoing factors. </P>

price range will be subject to then-current market conditions, continuing discussions with the Representatives and the volatility in the securities markets. In any event, the Company confirms to the Staff that the bona fide price range will comply
with Item 501(b)(3) of <FONT STYLE="white-space:nowrap">Regulation&nbsp;S-K&nbsp;and</FONT> CD&amp;I 134.04, unless otherwise approved by the Staff. </P>

Securities Issued as Compensation </I>(the &#147;<B><I>AICPA Practice Guide</I></B>&#148;). In addition, the Company&#146;s Board of Directors considered numerous objective and subjective factors, along with input from management and third-party

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Through December 2019, the Company utilized the <FONT STYLE="white-space:nowrap">option-pricing</FONT> method (&#147;<B><I>OPM</I></B>&#148;),
which is an accepted valuation method under the AICPA Practice Guide, for determining the fair value of its common stock. The OPM uses option theory to value the various classes of a company&#146;s securities in light of their respective claims to
the enterprise value. Under this method, total shareholders&#146; equity value is allocated to the various share classes based upon their respective claims on a series of call options with strike prices at various value levels depending upon the
rights and preferences of each class. A Black-Scholes closed form option pricing model is employed in this analysis, with an option term assumption that is consistent with the expected time to a liquidity event and a volatility assumption based on
the estimated stock price volatility of a peer group of comparable public companies over a similar term. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For valuations performed in 2020 and 2021, in accordance with the AICPA Practice Guide, the
Company utilized a hybrid method (the &#147;<B><I>Hybrid Method</I></B>&#148;) of the OPM and the <FONT STYLE="white-space:nowrap">probability-weighted</FONT> expected return method (&#147;<B><I>PWERM</I></B>&#148;) for determining the fair value of
its common stock. The PWERM is a scenario-based analysis that estimates the value per share based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the Company, as
well as the economic and control rights of each share class. More specifically, the PWERM involves estimating the overall value of the subject company under various liquidity event scenarios and allocating the value to the various share classes
based on their respective claim on the proceeds as of the date of each event. These different scenarios typically include an initial public offering, an acquisition, or a liquidation of the business, each resulting in a different value. For each
scenario, the future value of each share class is calculated and discounted to a present value using an appropriate cost of capital. The results of each scenario are then probability weighted in order to arrive at an estimate of fair value for each
share class as of a current date. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Hybrid Method estimates the probability-weighted value across multiple scenarios and the OPM to
allocate the estimated equity value within one or more of the scenarios. In the Company&#146;s hybrid method, several types of future event scenarios were considered including IPO scenarios and other scenarios such as continued operations as a
private entity scenario and a dissolution. The enterprise value was determined for scenarios using various market approaches. Once the equity value was determined for each scenario, the Company used the OPM to allocate value in the stay private
scenario and the <FONT STYLE="white-space:nowrap">as-converted</FONT> basis to allocate value in the IPO scenarios, before applying a discount for lack of marketability (&#147;<B><I>DLOM</I></B>&#148;). The relative probabilities between the future
exit scenarios were determined by management based on an analysis of performance and market conditions at the time, including then current IPO valuations of similarly situated companies and expectations as to the timing and likely prospects of
future event scenarios. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company&#146;s Board of Directors and management developed estimates based on application of these approaches
and the assumptions underlying these valuations, giving careful consideration to independent third-party valuation reports, and whether any events occurred that would trigger any material changes to the business or would require adjustment to the
estimated fair value from the previous valuation date. These assumptions represented management&#146;s best estimates, which involved inherent uncertainties and the application of management&#146;s judgment. As a result, if management had used
significantly different assumptions or estimates, the fair value of the Company&#146;s common stock and their stock-based compensation expense could have been materially different. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In conclusion, the Company respectfully submits that the difference between the valuation as of each of the 2021 grant dates and the
Preliminary Price Range is reasonable. However, notwithstanding the above, assuming the Company prices its IPO is between $[***] and $[***] per share (without giving effect to any reverse stock split that the Company will effect prior to the
offering) as currently planned, once the actual IPO price has been determined, the Company anticipates retrospectively reassessing, solely for financial accounting purposes, the common stock fair value related to the options granted on
February&nbsp;26, 2021 and March&nbsp;1, 2021 at the IPO price. In the course of preparing this letter, the Company determined that such retrospective reassessment would be appropriate due to, among other things, the close proximity of such grant
dates to the filing of the Registration Statement with the Commission on March&nbsp;5, 2021 and the anticipated commencement of the Company&#146;s road show on March&nbsp;22, 2021. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Moreover, the Company advises the Staff that it does not currently anticipate issuing any additional options prior to the pricing of its IPO,
and any options granted on the IPO pricing date will be at the actual IPO price. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>The Company hereby further requests, pursuant to
Rule&nbsp;418(b)&nbsp;under the Securities Act of 1933, as amended, the return of the unredacted version of this letter.&nbsp;The Company believes that return of the supplemental information contained in this letter will protect the interests of
investors and is consistent with the provisions of the Freedom of Information Act by maintaining in confidence the potential valuation of the Company that may, if disseminated, negatively impact the trading in the common stock of the Company
