Prospectus Summary
Our Company, page 1

1.     Please expand your disclosure regarding Quilience and Nolazol to briefly
discuss your
       stage of development of these product candidates and your plans for
their development in
       the future. Further, given your risk factor disclosure on page 10,
please clarify whether
       you are pursuing FDA approval of one or both of the lead product
candidates for use in
       children.
2.     We note your statements throughout the prospectus that Quilience and
Nolazol are
       "novel" pharmaceutical products and agents, yet the active molecule in
these product
       candidates is a controlled release formulation of mazindol, which has
been previously

         approved in an immediate release form. Please revise the use of the
term "novel"
         throughout the prospectus as appropriate.
Risks Associated With Our Business, page 2

3.       Please include a bullet point describing the risks related to the fact
that over 70% of your

you after the offering.

4.       Please supplementally provide us with copies of all written

5.       We note your disclosure that you have not received regulatory
clearance to conduct the
         additional clinical trials that are necessary to be able to submit an
NDA to the FDA for
         Nolazol. Please revise your disclosure to specify the regulatory

         conduct additional trials and describe any additional steps involved
in obtaining the
         regulatory clearance.
Risks Related to Our Intellectual Property, page 25

6.       Please add a risk factor, or revise in the appropriate risk factor, to
address the limitations
         of patents protecting the method of use as opposed to other types of
patents, such as a
         composition of matter patent.
Use of Proceeds, page 42

7.       We note that the net proceeds will be used to further develop mazindol
CR for use in
         Quilience and Nolazol. Please revise your disclosure to specify how
far in the clinical
         development you expect to reach with the net proceeds for each of the

Business
Our Development Pipeline, page 57

8.       We note that your pipeline table includes product candidates with
regard to which you do
         not provide any information (NLS 10, NLS-13 and NLS-14) or provide
limited
         information (NLS-2, NLS-3 and NLS-4). Please remove these product
candidates from the
         pipeline table or tell us why you believe these product candidates are
material to your
         business. To the extent you believe these product candidates are
material, please provide
         disclosure regarding these product candidates, including whether you

Our Solution: Quilience for Narcolepsy - A Well-Suited Approach for the Disease
Pathology ,
page 62

9.       We note that in your pipeline table on page 57, it suggests that you
have completed Phase
         2 studies for Quilience. However, you do not provide a description of
any studies
         conducted to date with respect to Quilience and further disclose that
you have not yet
         submitted an IND application or CTA. Please revise your disclosure or
the pipeline table
         to reconcile this discrepancy. To the extent you have completed any
clinical trials to date,
         please provide a description of these trials.

10.      We note your statement of belief that Quilience may qualify for the
Breakthrough
         program "based on positive real-world evidence using the same outcome
measures
         utilized in Phase 3 clinical trials." Please revise your disclosure to
explain what this
         means.
Our Solution: Nolazol - The Efficacy of a CII Stimulant with Improved Safety
and Tolerability,
page 67

11.      You make several assertions regarding the safety and efficacy of your
product candidates.
         For example, on page 67, you state that "Nolazol has the right balance
of safety and
         efficacy," that Nolazol demonstrated "evidence of efficacy and safety"
in your Phase 2
         clinical trial, and that Nolazol has "comparable efficacy, improved
safety" compared to
         CII treatments in use today and is "a more effective treatment than
the available non-
         stimulants." Safety and efficacy determinations are solely within the
authority of the FDA
         (or applicable foreign regulator). Please revise or remove
statements/inferences
         throughout your prospectus that your product candidates are safe
and/or effective.
Manufacturing and Suppliers, page 74

12.      We note that you rely on a single source for the production of your
drug substance. Please
         disclose the material terms of your agreement with this supplier and
file the agreement as
         an exhibit to the registration statement, or tell us why you do not
believe this is
         required. See Item 601(b)(10) of Regulation S-K.
Intellectual Property, page 75

13.    Please expand your disclosure to clarify the type of patent protection
your applications
       covering mazindol CR for the treatment of ADHD and narcolepsy provide
(e.g.,

14.      You disclose that as all of the companies were owned by the same
shareholders, the
         Merger was considered to be a common controlled transaction. Please
tell us the
         ownership interests of NLS-0 Pharma Ltd., NLS Pharma Ltd. and NLS-1

         both before and after the Merger. If any of the ownership percentages
