                  Schedule TO-I filed on November 20, 2019
                  File No. 005-88806

  Dear Mr. Stein:

         The staff in the Office of Mergers and Acquisitions has reviewed the
filing listed above,
  and we have the comments set forth below. All defined terms used herein have
the same
  meaning as in the Offer to Exchange Eligible Options for New Options (the
"Exchange Offer")
  attached as Exhibit (a)(1)(A) to the Schedule TO-I. In some of our comments,
we may ask you
  to provide us with information so we may better understand your disclosure.

         Please respond to this letter by amending your filing, by providing
the requested
  information or by advising us when you will provide the requested response.
If you do not
  believe our comments apply to your facts and circumstances or do not believe
an amendment is
  appropriate, please tell us why in your response.

         After reviewing any amendment to your filing and the information you
provide in
  response to these comments, we may have additional comments.

  Schedule TO-I

  Item 7. Source and Amount of Funds or Other Consideration

      1. The cross reference in Item 7(b) to Section 6 of the Exchange Offer
appears to be
         inappropriate, as Section 6 sets forth the conditions to the
consummation of the Exchange
         Offer rather than any material conditions to any financing of
consideration to be provided
         in the Exchange Offer. See Item 1007(b) of Regulation M-A. Please
revise.
 Item 10. Financial Information

   2. Please revise Item 10(a) to include the issuer's book value per share as
of the date of the
      most recent balance sheet presented. See Item 1010(a)(4) of Regulation
M-A. Please
      revise to provide this information in the Offer to Purchase or in
documents incorporated
      by reference.

Item 12. Exhibits

   3. We note that the offer materials appear to have been distributed only via
email. In your
      response letter, please explain why you believe this method of
dissemination is
      appropriate under the circumstances of the Exchange Offer, taking into
consideration the
      characteristics of the subject security holders and your normal means of
communicating
      with employees. As an example, discuss whether all employees who are the
subject of the
      offer have access to corporate email and whether this is your typical way
of
      communicating with them.

Exhibit (a)(1)(A)   Exchange Offer

Eligible Holders; Eligible Options; the Proposed Exchange; Expiration and
Extension of the
Exchange Offer, page 15

   4. We note that the Term "Eligible Holders" excludes employees who have
received a
      notice of termination prior to the commencement of the Exchange Offer and
employees
      who, between the commencement date and the Expiration Time, either
receive a notice of
      termination or submit a notice of resignation. Please clarify, however,
whether the term
      "Eligible Holders" includes employees who have submitted a notice of
resignation prior
      to the commencement date of the Exchange Offer but are still employees as
of the
      Expiration Time.

Procedures for Tendering Eligible Options, pages 18-19

   5. See our comment above regarding the method of disseminating the offer
materials. We
      note your disclosure throughout the Exchange Offer indicating that only
tenders
      submitted via email will be accepted. In your response letter, please
explain why you
      believe restricting the means of tendering to this process under all
circumstances is
      acceptable.

   6. Please refer to the following statement: "Subject to Rule 13e-4 under the
Exchange Act,
      we also reserve the right to waive any of the conditions of the Exchange
Offer or any
      defect or irregularity in any tender with respect to any particular
Eligible Options or any
      particular Eligible Holder." While you may reserve the right to waive
defects or
      irregularities of tender as to individual tendering Eligible Holders, the
conditions of the
      Exchange Offer must be the same for everyone. Please revise the language
regarding
      waiver of offer conditions.
    7. Please refer to the following statement: "Subject to our rights to
terminate and amend the
      Exchange Offer in accordance with Section 6 ("Conditions of the Exchange
Offer") . . ."
      It appears that the cross-reference to Section 6 should instead be to
Section 13
      ("Extension of the Exchange Offer; Termination; Amendment"). If so,
please revise
      accordingly.

Withdrawal Rights, pages 19-20

   8. See our comments above regarding the methods of dissemination and tender.
We note
      your disclosure throughout the Exchange Offer indicating that only
withdrawals of
      tenders submitted via email will be accepted. In your response letter,
please explain why
      you believe restricting the means of withdrawing tenders to this process
under all
      circumstances is acceptable.

Conditions of the Exchange Offer, pages 20-22

   9. Refer to the following statement: "[A]ny general suspension of, or
general limitation on
      prices for, or trading in, securities on any national securities exchange
in the United
      States or in the over-the-counter market." Please revise to clarify what
would be
      considered a limitation on prices for securities.

   10. Refer to bullet point seven on page 21. It is not clear what mandatory
or voluntary
       limitations by "any governmental, regulatory, administrative agency or
authority" might
       affect extensions of credit to you. Please revise to explain or provide
examples, here or in
       an appropriate section of the Offer to Exchange. Alternatively, consider
modifying the
       condition to more narrowly tailor it to the circumstances that could
affect Cidara.

   11. Refer to bullet eight on page 21. This condition will be triggered by an
"extraordinary or
       material adverse change in U.S. financial markets generally, including a
decline of at
       least 10%..." Revise the condition to quantify what would be considered
materially
       adverse or extraordinary for purposes of this condition, beyond the
enumerated 10%
       decline in your share price. In addition, revise the condition to
specify whether the
       decline would be measured at expiration or whether the condition could
be "triggered" at
       some earlier point while the Exchange Offer is pending, even if your
share price
       rebounds by the Expiration Time.

   12. Refer to the third sentence in the last paragraph in this Section on
page 22. Here you
       state that conditions may be waived "at any time and from time to time
prior to our
       acceptance of your tendered Eligible Options for exchange..." Offer
conditions must be
       asserted or waived as of the Expiration Time, rather than the date of
acceptance. That is,
       an event or non-occurrence of an event after expiration cannot be the
basis for
       abandoning an offer. Please revise your disclosure here accordingly.
 Conditions of the Exchange Offer, pages 23-24

   13. Please revise the table showing the number of shares underlying Eligible
and New
       Options beneficially owned by directors and executive officers to
include the percentage
       of Eligible Options held by each such person. See Item 1008(a) of
Regulation M-A.

and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
