to the first sentence of prior comment 5 and will review your
                                                        revised disclosure when
provided in a future amendment. With respect to the second
                                                        sentence of that
comment, please briefly disclose the reasons, as indicated in your
                                                        response, as to why you
cannot disclose at this time an estimate of the amount and sources
                                                        of other funds

                                                        appear that the
proceeds from this offering will be sufficient to fund any of your product
                                                        candidates through
