       Overview, page 1

   1.                                                   We note your response
to prior comment 1 and your updated disclosure which states, in
                                                        part, that your
clinical trial was conducted to "demonstrate" the safety and efficacy of BT-
                                                        11. Safety and efficacy
are determinations that are solely within the purview of the FDA
                                                        and foreign regulators.
Please revise your statement here and in Business to remove any
                                                        implication that the
Phase 2 trial of BT-11 demonstrated safety and efficacy.

                                                        We further note your
statement that the Phase 2 trial was not conducted to establish
                                                        statistical
significance, but rather to inform the design of the Phase 3 trial. Your
disclosure
                                                        on page 111 indicates
that goal of the Phase 2 trial was to establish the safety and efficacy
