Note 1. Background, page F-6

4.       We have reviewed the ownership interests in the three companies prior
to the merger as
         set forth in your response to prior comment 14 and note your belief
that in accordance
         with ASC 805-50-30-5 this was a common controlled transaction.
However, we note
         that no individual held more than 50% of the voting ownership interest
of each entity.
         Please revise your disclosure to state, if true, that due to the high
degree of common
         ownership amount the three companies and because individual investor's
ownership are in
         substance the same after the transaction, that this was deemed to be a
nonsubstantive
         merger, with no step up in basis of the assets and liabilities in the
merger.

5.       We have reviewed your revised disclosures in response to prior comment
16 and have the
         following additional comments:
           With reference to ASC 606-10-25-19, please more fully explain how
you determined
              that the promises you have identified within the contract (i.e.
the license, and
              promised services with respect to (i) development and (ii)
participation in a steering
              committee) are not distinct. In this regard, specifically clarify
why each good or
              service promised has no value to Europharma on a stand-alone
basis;
           Explain your basis for bundling these promises into your License
Performance
              Obligation. Also, as required by ASC 606-10-25-31, please explain
how the use of
              an input method as a measure of progress towards completion of
the License
              Performance Obligation using development costs meets the overall
objective of
              depicting your performance in satisfying this bundled performance
obligation.
              Specifically identify the patterns of performance of each
nondistinct promise and the
              judgement used in determining your stated measure of progress in
the combined
              performance;
           Clarify how you considered the guidance in ASC 606-10-55-50 through
55-53 in
              accounting for the $2,500,000 upfront payment. In particular,
explain how you
              assessed whether there was a transfer of a promised good or
service; and
           Provide the disclosures required by ASC 606-10-50-17 and 50-18.
