on the cover page and on page 185 to also take into account
commissions. We note your disclosures elsewhere in the prospectus

2.       We note your references to your product candidates as "first-in-class"
on page 1 and
         throughout the registration statement. This term suggests that the
product candidates are
         effective and likely to be approved. Please delete these references
throughout your
         registration statement. If your use of these terms was intended to
convey your belief that
         the products are based on a novel technology or approach and/or is
further along in the
         development process, you may discuss how your technology differs from
technology used
         by competitors and, if applicable, that you are not aware of competing
products that are
         further along in the development process. Statements such as these
should be
         accompanied by cautionary language that the statements are not
intended to give any
         indication that the product candidates have been proven effective or
that they will receive
         regulatory approval. Additionally, with respect to TP-03, there are
existing FDA
         approved treatments for rosacea.
3.       We note your statement that you estimate that the number of Demodex
blepharitis cases
         may be as high as approximately 25 million based on your internal
studies, and your other
         references to your research and surveys in the Summary. Please remove
discussions of
         your surveys from the Summary, and in the Business section, provide
additional details
         regarding the surveys so that an investor may understand their
significance, including
         which types of ECPs were included in the survey, how the surveyed ECPs
and patients in
         eye care clinics were selected, whether there was any ECP education
that took place
         between May 2019 and May 2020 that may have led to a rise in the
number of
         diagnoses, and what information regarding the indication and product
candidates were
         provided to those surveyed. Please also revise to provide balancing
disclosure regarding
         the small number of ECPs and patients surveyed. Also explain the basis
for why you
         believe there may be 25 million Demodex blepharitis patients when you
state on page 2
         that your research also indicates 58% of patients presenting to ECP
offices have
         collarettes indicative of Demodex blepharitis and that there are 20
million patients who
         suffer from blepharitis.
4.       Please revise the pipeline table on page 2, which also appears on page
108, so that it
         reflects the current status of your product candidates. As such,
please remove the grayed
         out portion of the arrow for TP-04, and also shorten the length of the
arrows for
         the preclinical studies that are not yet completed. For example, we
note your disclosure on
         page 133 that you are conducting pre-clinical studies for TP-04.
Please also expand your
         disclosure on page 133 to state that you will need to obtain an IND
for TP-04 prior to
         commencing trials in the U.S., which you explain on page 19.

5.       Please include a statement citing the number of people with
collarettes that do not have
         Demodex blepharitis.
6.       Please remove the comparisons of the blepharitis market to the dry eye
market and your
         TP-03 product to Allergen's Restasis in your Summary section.
Additionally, tell us why
         you believe it is appropriate to make such comparisons when there are

regulatory approval status
         and company operating history.
Our Approach: TP-03 , page 3

7.       We note your statements on page 4 and elsewhere that your results are
  highly statistically
         significant.    Please limit your discussions of trial results in the
Summary section to
         statements regarding the primary endpoints and whether they were met,
or that the trials
         and endpoints were exploratory, as applicable. The discussion of
specific p-values and
         whether they are statistically significant should be in the Business
section, where you
         should also explain how statistical significance relates to FDA
approval and what you
         mean by "highly" statistically significant.
8.       We note your statement on page 4 regarding the    robust and
consistent clinical efficacy
         of TP-03 that you observed in your Phase 2 clinical trials, as well as
"meaningful and
         consistent clinical efficacy and safety results" from your Phase 2
program. You also refer
         on page 6 to "[c]ompelling efficacy and safety data" from your Phase 2
program, on page
         7 that you observed in Phase 2 trials that TP-03 "results in
collarette cure and mite
         eradication," and your Figure 15 advertises a key advantage of TP-03
as its "Efficacy and
         Efficiency." Please revise these and all similar statements throughout
your prospectus that
         state or imply that your product candidates are safe or effective as
these determinations
         are solely within the authority of the FDA and comparable regulatory
9.       Please explain the basis for the amounts set forth in the following
statement on page 5: "In
         the United States, MGD prevalence has been found to be approximately
two-thirds of that
         of the estimated 34 million dry eye patient population." We note that
on page 3,
         you state the diagnosed population for dry eye was over 6 million in
2015 and similar
         levels have been maintained since.
10.      The footnotes to the graphic on page 5 indicate the Saturn trials are
pending FDA
         feedback. Please disclose this in your discussions of the Saturn
trials and describe this
         process and expected timeline. Please also increase the font size of
the footnotes to the
         graphic to make them more legible.
11.      Please describe how the formulation of TP-03 that is expected to
support your NDA
         submission for Demodex blepharitis is different than the formulation
of TP-03 used in
         certain of your prior trials.
Our Strengths and Differentiation, page 6

12.      Please balance your first bullet to explain that based on FDA
feedback, your Phase 3 trials
         will be using primary endpoints that are more stringent than the ones
used in your Mars
         and Jupiter trials and involve longer durations. Also explain that you
expect to enroll 700
         patients in your two Phase 3 trials as compared to your largest trial
to date with 54
         patients, that all your other trials were conducted outside of the
U.S., and that the FDA has
         not yet approved your trial designs.

referenced, or otherwise
         disclose information regarding the trial, including the number of
participants and the
         results. In particular, you state    only 7% of patients without

but who were performing

21.      On page 117, please revise the disclosure to state why a comparison to
dry eye is being
         presented in a study that you state was conducted to determine ECP
awareness of the
         connection between collarettes and Demodex infestation. With respect
to the graphic,
         please revise as necessary to clarify if any of these patients had
overlapping diagnoses, in
         particular with respect to MGD and dry eye.
22.      On page 120 please explicitly state the basis for your comparison to
dry eye and why that
         comparison is meaningful. Please note whether there was any overlap
between patients
         that had both collarettes and were on a prescription therapeutic for
dry eye disease and
         explain how the survey results relate to your stated belief that there
is a significant
         population for Demodex blepharitis.
