   1.                                                   Please revise and
continue to update your disclosure here and in the Exchange Ratio
                                                        discussion on pages

                                                        net cash calculation.
Please also provide examples of estimated percentage ownership
                                                        based on Seneca's level
of net cash at the Effective Time.
   2.                                                   Please explain to us
why you have included two separate calculations of the post-merger

ownership at the bottom of page 1. In particular, please explain why
                                                        you have only included
50% of the shares subject to the Equity Warrants in the first

         Merger Seneca equity holders will hold approximately 26.2% of the
combined company
         (assuming Seneca net cash between $4.5 million and $5.0 million).

         Please also update this section to include a cross-reference to the

         discussion that appears later in the document.
3.       Please revise your disclosure here and in the preceding letter to
stockholders of Seneca
         Biopharma, Inc. and Leading BioSciences, Inc. to disclose the identity
of the Investor.
4.       Per your description of the CVR Agreement on page 146, please update
your disclosure
         here and on page 18 to clarify, if true, that holders of Seneca common
stock immediately
         prior to the effective time will only receive proceeds from Legacy
Monetization Events to
         the extent that such proceeds exceed $300,000 in the aggregate. Please
also revise to
         confirm whether the up-front payment of $100,000 received by Seneca
for the license
         NSI-189, as well as any additional proceeds received by Seneca prior
to the Effective
         Time, will be treated as a Legacy Monetization.

including a
         description of its lead product candidates and the status of its
current clinical programs.
         Refer to Item 3 of Form S-4.
6.       Given that LBS has not yet initiated a Phase 2/3 or Phase 3 clinical
trial for any of its
         product candidates, please revise your statement that LBS is a "late"
clinical stage
         biopharmaceutical company here and on pages 185 and 231.
Nasdaq Capital Market Listing , page 24

7.       Please revise your disclosure here and on the cover page to indicate
whether the Nasdaq's
         determination regarding the initial listing application will be known
at the time
         stockholders are asked to vote on the merger agreement and whether you
have had any
         discussions with Nasdaq concerning the initial listing application.
Please also revise
         to include a discussion of the potential consequences to investors,
including the ability of
         investors to buy and sell shares of common stock, if Nasdaq does not
approve the listing
         application of the combined company, but Seneca and LBS proceed with
the merger.
         Finally, please revise your disclosure to indicate whether you expect
Seneca's current
         failure to comply with Nasdaq's minimum bid price requirement to have
any impact on the
         initial listing application of the combined company.

your financial
         advisors. Please provide more details regarding the selection process

         advisors, including the qualifications considered.
Seneca Reasons for the Merger, page 93

10.      We note your disclosure throughout the document that the Exchange
Ratio formula is
         based upon an LBS valuation of $97.85 million. However, your
disclosure on page 103
         indicates that Cassel Salpeter's analysis of comparable public
companies indicated an
         implied equity value reference range for LBS of $58.4-87.6 million and
that Cassel
         Salpeter's analysis of comparable IPOs indicated an implied equity
value reference range
         for LBS of $58.1-82.9 million.

         Please revise your disclosure to discuss the reasons why Seneca's
board determined that a
         higher LBS valuation is fair to, advisable and in the best interests
of Seneca and its
         stockholders.

with respect to

section, including the
         compensation that may be paid to executive officers in exchange for
the cancellation of
         their options.

regarding treatment
         of the transaction under Section 368(a) and remove language stating
that it is intended
         that, or generally, certain material tax consequences will apply. In
addition, please clearly
         state that the conclusion is the opinion of counsel. Please also
remove any statement that
         assumes the material tax consequences at issue (e.g., "If the Merger
qualifies as a

16.      Please revise your disclosure to (i) explain the role of the CVR Agent
and (ii) discuss how
         the CVR Holders' Representative will be selected. Please also revise
to clarify whether
         Seneca's obligations pursuant to the CVR Agreement will become the
obligations of the
         combined company following the Effective Time.
17.      We note your disclosure that (i) Seneca will be entitled to use all or
a portion of the
         Ongoing Support Funding ($500,000) for expenses related to a Legacy
Monetization, (ii)
         that Seneca will pay $500,000 (i.e. the entire amount of the Ongoing
Support Funding) to
         the CVR Holders' Representative at the Effective Time and that (iii)
the CVR Holders'
         Representative will be entitled to be reimbursed from a segregated
escrow account for
         costs related to any Legacy Monetization.

         Please update your disclosure to clarify (A) whether the intent of the
arrangement is that
         the CVR Holders' Representative's fee will be reduced by amounts used
by Seneca for
         expenses related to a Legacy Monetization and (B) the amount of funds
that will be placed
         in the segregated escrow account and the identity of the escrow agent.
18.      We note your disclosure that each CVR will entitle its holder to
receive a pro rata portion
         of 80% of the net proceeds from any Legacy Monetization. We further
note that "net
         proceeds" is defined as gross proceeds less deductions. Please revise
your disclosure to
         explain how the remaining 20% of net proceeds from any Legacy
Monetization will be
         allocated.

         We further note your disclosure on page 146 that the gross proceeds of
any monetization
         will be reduced by the amount of the Ongoing Support Funding. Please
update your
         disclosure here and in the Q&A in your document to clarify, if true,
that the $500,000 of
         Ongoing Support Funding must be repaid before the net proceeds of any
Legacy
         Monetization are distributed to legacy Seneca stockholders.

Overview, page 186

20.      Please update LBS's pipeline chart to clarify whether each of the
product candidates in the
         chart is wholly-owned or licensed from a third party.

         In addition, we note the inclusion of an oral protease inhibitor for
glucose control and
         autoimmune disease in LBS's pipeline table. Given the status of
development and the
         limited disclosure in the prospectus regarding these programs it seems
premature to
         highlight theses program prominently in LBS's pipeline table.
Accordingly, please revise
         to remove these programs from the pipeline table or advise.
21.      We note the disclosure throughout this section stating that "evidence
suggests that
         digestive enzyme leakage...", "genetic evidence supporting the
association of proteases...",
         "there is building evidence that...", "multiple lines of evidence
implicate aberrant protease
         activity", etc. Please revise these and similar statements to clearly
described where this
         evidence was observed and whether it was based on studies or trials
conducted by LBS or
         by a third party.
Our Strategy, page 187

22.      Please update this section, or another part of the Description of
LBS's Business as
         appropriate, to discuss whether you have identified the first
indication(s) for which you
         anticipate seeking marketing approval for LB1148 and the clinical
trials that you will be
         required to conduct to support your initial application(s) for
marketing approval.
23.      Please remove the statement that LBS intends to "rapidly" develop
LB1148 as well as any
         other statements that state or imply that you will be successful in
developing and
         progressing your product candidates in a rapid or accelerated manner
as these statements
         are inherently speculative.
24.      Please remove here and throughout to remove any statements that LBS's
product
         candidates are "best-in-class" or "first-in-class" because the term
suggests that the product
         candidates are effective and likely to be approved by the FDA. If your
use of the term
         was designed to convey your belief that your product candidates are
based on a
         differentiated technology or approach, you may further discuss how
your technology or
         approach differs from those of your competitors.

clinical trial provide
         evidence that LB1148 can reduce the time to return to bowel function
in GI surgery and

         that three patients treated with LB1148 who were assessed for
postoperative adhesions did
         not develop postoperative adhesions.

         Please balance your disclosure to disclose the stage of these trials,
whether the trials were
         powered for efficacy, and any relevant limitations. We further note
that your disclosure on
         page 194 regarding the postoperative adhesions assessment states that
the surgeon for one
         of the three patients was not an investigator and that postoperative
adhesions were not
         formally assessed. Please revise your statements on page 187 to
reflect the discussion on
         page 194.
Unmet Needs in Intestinal Barrier Dysfunction and the Opportunity for LB1148,
page 187

26.      We note your statement here that LB1148 "is expected to confer
multiple benefits" as well
         as your statement elsewhere that LB1148 "is expected to improve
patient outcomes." We
         similarly note your statements that data suggest that LB1148 may
prevent postoperative
         adhesions in surgical patients, that LB1148 may offer distinguishing
benefits for patients
         providers and that LB1148 may reduce overall length of stay in both
the hospital and ICU
         settings. These are just examples.

         Please revise your disclosure throughout your prospectus to revise
these and similar
         statements to eliminate conclusions or predictions that LB1148 is or
will be effective as
         determinations of efficacy are solely within the authority of the FDA.
You may provide a
         summary of the objective data from your preclinical studies and
clinical trials without
         including conclusions related to efficacy.

29.      Please revise your disclosure to state whether PB101 is wholly-owned

conducted the studies
         referenced later in this section or if they were conducted by a
third-party. Further, please
         present more detailed information regarding the studies in animal
models that indicate that
         PB101 can preserve intestinal issue following intestinal injury.
Alternatively, explain to us
         why this disclosure would not be material.

         Finally, please revise your disclosure to indicate the status of a
