3.       We note your response to prior comment 7. Please disclose whether your
exclusive forum
         provision applies to actions arising under the Securities Act. In that
regard, we note that
         Section 22 of the Securities Act creates concurrent jurisdiction for
federal and state courts
         over all suits brought to enforce any duty or liability created by the
Securities Act or the
         rules and regulations thereunder. If this provision applies to claims
arising under the
         Securities Act, then please disclose that there is uncertainty as to
whether a court would
         enforce such provision and to state that shareholders will not be
deemed to have waived
         your compliance with the federal securities laws and the rules and
regulations thereunder.
         If this provision does not apply to actions arising under the
Securities Act, please also
         ensure that the exclusive forum provision in the governing documents
states this clearly.

         generally, certain material tax consequences will apply. Refer to
Section III of Staff Legal
         Bulletin No. 19 for guidance. To the extent you will file a short-form
opinion
         and counsel's opinion will be under "U.S. Federal Income Tax
Consequences to U.S.
         Holders" in the prospectus, please revise your disclosure to provide a
firm conclusion in
         this section regarding the material federal income tax consequences to
investors, clearly
         state that the conclusion is the opinion of counsel, and remove any
statement that assumes
         the material tax consequences at issue (e.g., "[i]f the Domestication
qualifies as an F
         Reorganization"). Please also remove the statement that this section
is for informational
         purposes only.

7.       We refer to your revised disclosure in response to prior comment 24,
which states the
         occurrence of various adverse events. Please revise to specifically
disclose all serious
         adverse events that occurred in the various prior trials (and not just
the most frequent),
         whether or not treatment related. Also, as previously noted, please
define or otherwise
         explain each of the terms "complete response," "durable response" or
"duration of
         response," "partial response," "progression-free survival," "overall
survival" (and noting
         differences in how the terms are defined if such terms differed among
the trials). We also
         continue to note that you have included references to various medical
journals in your
         discussion of trial results for abexinostat. As previously noted,
referring investors to
         sources outside of your filing for material information is not
sufficient to meet your
         disclosure obligation. Please revise to ensure all material
information is included in your
         filing.
8.       We note your revised disclosures in response to prior comments 26 and
27. However, we
         continue to note references to signs of efficacy in your discussions
of abexinostat and with
         respect to XP-105. Please revise any statements that suggest your
product candidates are
         effective.
9.       We refer to your revised disclosure on page 177 in response to prior
comment 28. Please
         further revise to clarify which of your partners are supplying the
drugs in combination
         trials for free and which partners are supplying them at wholesale
prices. In addition, to
         the extent that your partners are providing these drugs as part of a
collaboration or other
         type of material agreement, please revise your disclosure to include
the material terms of
         such agreements and file such agreements as exhibits.
