       Preliminary Proxy Statement on Schedule 14A

       Interests of Certain Persons in the Business Combination, page 33

   1.                                                   We note that the
initial shareholders agreed to waive their redemption rights. Please
                                                        describe any
consideration provided in exchange for this agreement.
   2.                                                   We note that the Board
of Directors considered the potential conflicting interests of
                                                        Helix's Sponsor,
directors, and officers when evaluating the Business Combination. Please
                                                        clarify how the board
considered those conflicts in negotiating and recommending the
                                                        business combination.

Risk Factors Related to Helix and the Business Combination
Directors and officers of Helix have potential conflicts of interest in
recommending that Helix's
shareholders vote in favor of approval, page 76

3.       Please highlight the risk that the sponsor may be incentivized to
complete an acquisition
         of a less favorable target company or on terms less favorable to
shareholders rather than
         liquidate given how much the sponsor stands to benefit from the
completion of a business
         combination.
The Business Combination Proposal, page 110

4.       We note that your disclosure of the Post-Business Combination
Ownership Structure on
         page 112 assumes two redemption scenarios. Please revise to include a
sensitivity analysis
         with a range of redemption scenarios, including minimum, maximum and
interim
         redemption levels.
5.       Please revise to disclose all possible sources and extent of dilution
that shareholders who
         elect not to redeem their shares may experience in connection with the
business
         combination. Provide disclosure of the impact of each significant
source of dilution,
         including the amount of equity held by founders, convertible
securities, including warrants
         retained by redeeming shareholders, at each of the redemption levels
detailed in your
         sensitivity analysis, including any needed assumptions.
6.       It appears that underwriting fees remain constant and are not adjusted
based on
         redemptions. Revise your disclosure to disclose the effective
underwriting fee on a
         percentage basis for shares at each redemption level presented in your
sensitivity analysis
         related to dilution.
Background of the Business Combination
Negotiations with MoonLake, page 132

7.       With reference to the disclosure on page 132, please revise to discuss
who introduced you
         to MoonLake and the individuals and parties who were involved in the
initial
         communications and negotiations.
8.       We note your disclosure on page 132 that you conducted preliminary due
diligence on,
         and held discussions with, 58 companies and only executed one letter
of intent, which was
         with MoonLake. Please revise to disclose whether you entered into any
confidentiality
         agreements with any potential target companies other than MoonLake,
and if so, how
         many and the Board's reasons for terminating discussions with such
companies.
9.       Please revise your disclosure in this section to further describe the
basis for the Helix
         Board's belief that MoonLake had the ability to generate $1 billion in
revenue per year
         within five to seven years given the inherent uncertainty of drug
development. Please
         remove any reference to the ability to "de-risk" as such reference
implies that it is possible
         to mitigate the risk associated with drug development and describe why
the Board valued

         comparisons to bimekizumab which has yet to be approved for
commercialization.
10.      We note your disclosure that Helix sent an initial draft letter of
intent to MoonLake in
         which it proposed the terms of a business combination. Please revise
to clarify how the
         transaction structure and consideration evolved during the
negotiations, including the
         proposals and counter- proposals made during the course of
negotiations, with respect to
         the material terms of the merger, particularly as it relates to the
valuation of
         MoonLake. Please be sure to indicate which party first presented a
valuation figure and
         discuss each counterproposal so that investors can understand how this
term was
         negotiated and whether the valuation moved materially during this
period. Discuss the
         basis or bases presented in support of each valuation proposed and
what factors the Helix
         Board considered that led to an increase in the valuation of $10
million.
11.      Please clarify whether the financial models MoonLake provided Helix
management on
         June 4, 2021 are materially the same as the MoonLake Forecasts
discussed on page 144. If
         they are materially different, please tell us how they are different,
what changes were
         made and why such changes were made.
MoonLake Valuation Analyses, page 140

12.      With respect to the analyses where SVB Leerink selected certain
companies for purposes
         of comparison, please disclose whether any companies meeting the
selection criteria were
         excluded from the analyses, and if so, why they were excluded.
Certain Projected Financial Information, page 144

13.      We note your disclosure that MoonLake provided its internally derived
estimated risk-
         adjusted net revenues and unlevered free cash flow for the years
ending December 31,
         2021 through 2040 to Helix in the second quarter of 2021 for use as a
component of its
         overall evaluation of MoonLake and to SVB Leerink, which was
authorized and directed
         by Helix to use and rely upon such information for purposes of
providing advice to the
         Helix Board. We have the following comments regarding these forecasts:

                Describe the process undertaken to formulate the forecasts and
the parties who
              participated in the preparation of the forecasts. Clearly
identify the risk adjustments
              in arriving at risk-adjusted revenue.
                Disclose the material assumptions and estimates underlying the
forecasts, including
              MoonLake's revenue growth rates, operating costs, product
pricing, gross margins,
              etc. and the limitations of the forecasts. Provide investors with
sufficient information
              to evaluate the forecasted financial information and its
reasonableness.
                We note your disclosure that MoonLake provided the
risk-adjusted net revenues and
              unlevered free cash flow information to Helix in the second
quarter of 2021 in
              connection with its overall evaluation of MoonLake and to SVB
Leerink, among
              other things. Please tell us what other information was provided
to Helix and SVB
              Leerink at that time. If the other information provided included

              financial information, please disclose those projections or tell
us why they are not
              material to investors.
                Explain how you arrived at the probability of regulatory
approval and the nature of
              such adjustment and whether you applied the same regulatory
success rates for each
              of the pre-commercialization products, and if so, why.
                Explain whether management prepared multiple forecast
scenarios, and if so, whether
              the one presented in the document represents the average of the
scenarios or the most
              likely scenario. Explain how you weighted the various scenarios.
                Explain how management and the Board relied upon the forecasts
and how they
              determined that they are reasonable, particularly in light of the
length of the forecasts
              and since MoonLake is a clinical stage company with limited
operations and no
              approved products. Specifically, address the reliability of the
projections related to
              the later years presented.
                Explain to us the extent that you have considered providing
separate forecasted
              financial information for each product candidate based on its
stage of development.
                Please quantify the adjustments that Helix management made to
the unlevered free
              cash flow forecasts provided by MoonLake management and the
reasons for the
              adjustments. Disclose projected operating and other expenses in
addition to
              presenting an estimated net income (loss) amount.
                Disclose the date you assume SLK will be granted regulatory
approval for each
              indication for each significant market reflected in the forecast.
                Revise to more clearly define for the reader the use of
gross-to-net and proportion of
              days of treatment in estimating annual revenue per patient and
how management
              arrived at 33% and 90%, respectively.

         candidates. Safety and efficacy determinations are solely within the
authority of the FDA
         (or applicable foreign regulator) and are assessed throughout all

                Our novel tri-specific Nanobody, sonelokimab (   SLK   , also
known as M1095/ALX
              0761) is an IL-17A and IL-17F inhibitor that has clinically
demonstrated potential to
              drive disease modification in dermatology and rheumatology
patients.
                Specifically, dosages up to 120 mg showed rapid and significant
clinical benefit
              compared with placebo.
                In addition to these features, we believe that the strong
clinical results achieved to
              date uniquely position SLK for success.
                SLK showed notable therapeutic activity and a promising safety
profile.

              psoriasis as compared to the current standard of care provided by
IL-17A inhibitors.
                SLK demonstrates potential in major inflammatory diseases
driven by IL-17A and
              IL-17F, and clinical trials to date show high response levels
(PASI90 and PASI100
              scores (Figure 4)) in psoriasis, with a favorable benefit-safety
profile.
                We believe this data describes a benefit-risk profile that is
likely to be advantageous
              to the current standard of care and bimekizumab.
                Since inflammation in r-axSpA also impacts deep joint tissues,
we believe SLK has
              the potential to demonstrate significant efficacy when compared
to other therapies,
              considering the intrinsic characteristics of the Nanobody.
                Considering its aforementioned benefit-safety profile and the
potential for tissue
              penetration, we believe SLK could differentiate by elevating the
treatment goals to
              HiSCR75 and beyond, significantly bettering the current standard
of care, as well as
              other similar drugs targeting its mechanism of action.
                SLK has demonstrated in a Phase 2 study safety and efficacy in
psoriasis.

         Please revise your disclosure to eliminate any suggestion that your
product candidates
         have been or will ultimately be determined to be safe or effective or
to have demonstrated
         efficacy for purposes of granting marketing approval, including
comparisons to the
         current standard of care. In your revised disclosure, please replace
all claims or
         conclusions related to efficacy with a description of the objective
data resulting from the
         trials.

clinical development of
         SLK." Please revise this disclosure and any similar disclosure
throughout the prospectus
         to remove any implication that you will be successful in
commercializing your product
         candidates in a rapid or accelerated manner as such statements are
speculative.
Our Solution: The Tri-Specific Nanobody Sonelokimab (SLK), page 183

16.      We note your disclosure on page 185 stating that "SLK   s Phase 2
clinical trial data in
         psoriasis indicated that IL-17A/F inhibition provided by SLK is
potentially associated
         with a safety profile that is consistent with current IL-17A
inhibitors and is more
         favorable than bimekizumab, the other IL-17A/F product in
development." If you have not
         conducted actual head-to-head trials, please revise your disclosure
here and elsewhere to
         clearly state this fact and disclose why you believe these comparisons
are appropriate. If
         you provide disclosure regarding results from other trials, expand
your disclosure to
