          4.2 In order to permit the SPONSOR the opportunity to properly protect
     patent and proprietary rights relating to the Research Program, a copy of
     each proposed publication shall be provided to the SPONSOR thirty (30) days
     in advance of submission for publication to permit the SPONSOR time in
     which to prepare application(s) for letters of patent regarding the subject
     matter of such publication. Any final proposed publication provided to the
     SPONSOR shall be considered as acceptable for submission for publication
     unless the SPONSOR notifies BCM and O'MALLEY within thirty (30) days of
     receipt of the proposed publication that it requires additional time to
     secure patents on such Research Program, in which case the SPONSOR shall
     have an additional sixty (60) days to undertake such action before
     publication. The SPONSOR shall also receive final drafts of any proposed
     publication and the SPONSOR shall be named in the publication as the
     SPONSOR of the Research Program or, as the case may be, the licensee of
     such technology. The right to review publications as set forth herein shall
     extend only to the work product of O'MALLEY and the Project Team pursuant
     to the Research Program and not to the work product of other research
     conducted in the laboratories of O'MALLEY, or member of the Project Team,
     or in the laboratories of other researchers at BCM.

                      V. CONFIDENTIALITY OF INFORMATION

          5.1 SPONSOR and BCM may wish, from time to time, in connection with
     work contemplated under this Agreement, to disclose confidential
     information to each other. SPONSOR and BCM will use reasonable efforts to
     prevent the disclosure to third parties of any confidential information
     belonging to the other, and use such information only for the purposes
     expressed in this Agreement, during the term of the Agreement and for a
     period of three (3) years thereafter, provided that the receiving party's
     obligation hereunder shall not apply to information that:

            (1)   is already in the receiving party's possession at the time of
                  disclosure thereof;

            (2)   becomes part of the public domain through no fault or
                  unapproved action of the receiving party;

            (3)   is received from a third party having no obligations of
                  confidentiality to the disclosing party;

Page 3 of 17
<PAGE>
            (4)   is independently developed by the receiving party;

            (5)   is required to be disclosed under the laws of the United
                  States of America pursuant to a court order. However, BCM
                  shall do so only after promptly providing SPONSOR with notice
                  of the actual or proposed court order or motion or cause of
                  action seeking such an order and thereafter, as soon as
                  available, a copy of the, court order or proposed order, and
                  giving SPONSOR the opportunity to intervene or otherwise
                  contest or appeal such motion, cause of action or order. In
                  any such event, until such time as SPONSOR is acknowledged by
                  the court or duly appointed officer as being the only party
                  having standing to object to such action, BCM will promptly
                  advise the judge or duly appointed officer of this Agreement
                  and of all restrictions upon the disclosure of confidential or
                  proprietary information or data and shall employ and use best
                  efforts to cause testimony or physical copies relating thereto
                  to be made a sealed record of the court or other forum.

            5.2 SPONSOR may, at its own expense, provide such additional
     security measures to preserve and protect developed confidential and
     proprietary information as will not interfere with the ongoing
     investigation and Research process.

            5.3 The parties agree that sensitive, confidential and proprietary
     information will not be communicated using unsecured media including but
     not limited to cellular telephones or electronic mail.

                           VI. INTELLECTUAL PROPERTY

            6.1 BCM shall have sole and exclusive ownership rights to any
     invention of a product, device, process, or method, whether patentable or

     patentably distinct from and not dominated by CYGX's proprietary
     intellectual property disclosed and/or made available to BCM, O'MALLEY, and
     Project Team to enable and/or facilitate the Research Project, subject to
     the right of the sponsor to take an exclusive, or non-exclusive,
     royalty-bearing license to the invention, as set forth in Section 6.2
     below.

            6.2 BCM grants to SPONSOR the right of first review with respect to

                  with sufficient detail to evaluate the Invention.

            (3)   SPONSOR shall have forty-five (45) days after such
                  notification to evaluate the Invention and notify BCM, in
                  writing, that SPONSOR desires to license the Invention.

            (4)   Upon notification by SPONSOR of its desire to acquire rights
                  to the Invention, SPONSOR and BCM shall negotiate, in good
                  faith, for a period not to exceed sixty (60) days, unless
                  extended by mutual written agreement of SPONSOR and BCM, in an
                  effort to arrive at terms and conditions satisfactory to
                  SPONSOR and BCM for the license by SPONSOR of the Invention.

            (5)   If SPONSOR and BCM do not reach such agreement within said

TITLE: An "Orally  Regulable"  Antisense  Therapy for Breast Cancer:  Proposal
to CytoGenix, Inc.


INTRODUCTION/BACKGROUND/RATIONALE:

INTRODUCTION

      Based on our prior knowledge of steroid hormone receptors, we have
constructed a chimeric regulatory system for genetic therapy containing three
important modules that together constitute a regulable transcription factor: (I)
a domain able to bind a specific DNA-sequence, (II) a domain that regulates the
ability of the receptor to bind DNA upon administration of an exogenous chemical
(ligand) and (III) a domain with the potential to activate or repress
transcription. In order to regulate a specific target gene IN vivo, a desirable
chimeric regulator should contain the following features. The DNA-binding domain
should not bind to endogenous DNA elements in the nucleus and alter gene
expression. The ligand binding domain (LBD) must be stimulated by an easily
administerable, nontoxic drug which retains biological activity at low
concentrations without the interference of endogenous compounds. The regulation
mediated by the LBD should only occur in the presence of the ligand to guarantee
a finely controlled regulation without 'leaky" expression of the target gene in
absence of the drug. The activation (or repressor) domain must be sufficiently
potent to generate high expression (or tight repression) of the coupled target
genes. Our recent results indicate that our target "Gene Switch" regulatory
system approaches the ideal for "regulated gene therapy".

      Our current advanced version of the Gene Switch is composed of: (I) an
"activation domain" peptide from the p65 protein (NFkB subunit) which imparts
strong capacity for target gene activation; (II) a Gal4 DNA binding domain
peptide; (III) a mutated ligand binding domain of the human progesterone
receptor, which does not bind progesterone or other endogenous steroids, but
which can bind and be "activated" by antiprogestins such as mifepristone
(RU486). Mifepristone (or other antiprogestins) is relatively nontoxic even at
very high doses in humans (100+ mg/day). Moreover, it has no known IN vivo
effects in humans at the doses required for activation of the Gene Switch
(10-9M); or ~ 250 (mu)g/kg), including any effects on reproduction and neonatal
viability.

Page 11 of 17
<PAGE>
      We have had extensive expertise with this Gene Switch in our laboratory
over the past six years. It is a very effective activator of accompanying target
genes under conditions of transfection in tissue culture cells, in transgenic
mice, and more recently, in viral infection of mice carrying the
mifepristone-dependent regulator and a target gene. We long have considered that
the ideal mode of gene therapy would involve such viral vectors in which
PERSISTENCE of the virus would occur, but where no detectable expression of the
therapeutic gene would occur until the Gene Switch is activated by mifepristone.
WE RECENTLY HAVE ACCOMPLISHED THIS GOAL; and now feel that short-term
application to human gene therapy can occur.

      In order to facilitate initial delivery of the inducible system IN vivo,
adenoviral vector-mediated gene delivery was our choice of therapeutic approach.
Previously, such a means of delivery had inherent problems: (I) expression of
viral proteins in infected cells is believed to trigger a cellular immune
response that precludes long-term expression of the transferred gene; and (II)
the insert capacity of adenoviral vectors has been previously limited to 8 kb of
transgenic sequence. Recently an adenoviral vector (the "gutless" adenovector)
has been constructed which contains no viral coding sequences and possesses a
very large insert capacity (28 kb). Using this adenoviral vector in combination
with our inducible regulatory system should provide a "persistent" regulable
gene delivery system IN VIVO for use in human gene therapy.

      This "gutless" adenoviral (GAd) expression has displayed impressive
characteristics to date. The modified adenovirus vector can easily accommodate
both the Gene Switch coding sequence and a large target vector. It is produced
in tissue culture cells with the aid of a helper virus, which can be eliminated
later by purification (99.98%). The virus can be administered I.V. and takes up
residence in a number of tissues (e.g., liver, lung, muscle, etc.) and most
importantly, remains capable of activation for 2 years IN VIVO. In this way,
genes contained in the GAd may be turned "on" and "off" repeatedly over two
years, or perhaps a considerably greater time period. Additional benefits are a
distinct lack of immunotoxicity (NO viral proteins are produced from the GAd
vector) and a low-to-nonexistent basal expression in the absence of the
mifepristone inducer compound. Upon IM, IP, S.C. or oral administration of
mifepristone (or other antiprogestins) to mice, the target gene (in our proof of
principle experiments we use the growth hormone gene for ease of detection), is
activated to a tremendous level that results in serum levels in excess of 50
(mu)g/ml (50,000 x normal levels) - a level much greater than that achievable
with transgenic animals producing regulatable constitutive levels of growth
hormone. Withdrawal of mifepristone leads to a relatively rapid decrease in GH,
consistent with the drug's half-life (~20 hours) in animals.

      In an analogous manner, we will insert the reverse transcriptase (RT)
gene, the encoding sequences for desired ODNs for antisense and/or other
therapeutic nucleic acids, and the sequence encoding for the RT primer binding
site (PBS) into our gutless adenoviral vector, behind the mifepristone regulable
GeneSwitch. Plasmid(s) containing the RT gene, MCS for insertion of encoding
sequences, and the PBS will be provided by CytoGenix. Viral preparations will be
according to our established procedures. Virus will be tested for efficacy,
first in tissue culture cells, prior to administration to animals.

      In summary, we have developed a near-term genetic therapy, which can be
regulated by an orally effective, non-toxic, specific, activator ligand
(antiprogestin) which has minimal-to-no deleterious effects in the host species.
We feel this is an ideal way to administer gene therapy in a fully regulable
fashion. This gene therapy system is applicable to a wide variety of
anti-oncogenic therapeutic genes - and to a wide variety of tumors. As a primary
aim of the project, we will deplete normal breast cancer cells of SRA, a new
general coactivator for steroid hormone (i.e., ER, PR) receptor action.

SRA-ACTIONS AND RELEVANCE TO TUMORS

      The cloning and characterization of several transcriptional coregulators
has provided new insights into nuclear receptor-mediated gene regulation, and
their role in tumorigenesis needs to be evaluated. We recently reported the
isolation and functional characterization of SRA, a novel transcriptional
coactivator with remarkable features. Unlike other known coactivators, SRA
functions as an RNA transcript and is selective for steroid hormone receptors.
Recently, we found that SRA is overexpressed in steroid-dependent tumor tissues,
suggesting that SRA may play an important role in tumorigenesis. We therefore
planned to validate the role of SRA as biological marker for steroid-dependent
cancers. We are currently analyzing a large variety of human tissues and
correlating SRA expression with stage and type of the tumors. In addition, since
SRA coactivation does not require the ligand-binding domain of the receptors,
and since SRA coactivates Tamoxifen antagonized estrogen receptor in culture
cells, we believe that SRA may play an important role in tamoxifen-resistant
breast cancers. Thus, we will put SRA in perspective with regards to hormonal
status of primary human breast tumor tissues. To answer the important question
as to whether SRA alone is sufficient to cause tumorigenesis, our studies will
be complemented by the analysis of transgenic mice that overexpress SRA
specifically in the mammary glands. This model, when completed, will be tested
for antisense inhibition of SRA using the vectors described above.

ANIMAL TEST SYSTEMS

A. Transgenic SRA-Overexpression Breast Model

SRA has been introduced into animals transgenetically via an MMTV-breast
specific promoter. Our current analyses show a breast phenotype in the germline
SRA-overexpression animals; we predict an oncologically important model that
could be ideal for testing the antisense/catalytic therapeutic capabilities of
CytoGenix's proprietary ODN expression system.

B. An alternate "back-up" breast cancer exenograft model will be utilized in
addition to the SRA-overexpression model will be used to test the SRA-ODN
system. It is currently operative in the laboratory and the generation and
testing in this model are routine.

      The plasmid pssXD is approximately 6.26 Kb and was developed as a fusion
between two independent plasmids. When a desired sequence encoding for a given
ssDNA sequence is inserted into pssXD, and pssXD is subsequently transferred
into mammalian cells, pssXD produces detectable ssDNA (of any desired sequence)
which can be potentially used in antisense, sense, triplex, and/or catalytic
nucleic acid experiments. The plasmid encodes for one protein (reverse
transcripitase) which, in turn, directs the continued synthesis of a desired
ssDNA within the cell. The plasmid pssXD encodes for the neomycin (Neo)
resistance gene for positive selection in eukaryotic cells. It also contains
ColE origin of replication and the prokaryotic bla promoter driving Kanamycin
resistance for propagation in E. coli. The plasmid is provided with two Not I
cut sites with a small stuffer region between these two cut sites and a Pac I /
Bam HI MCS for the insertion of the desired sequence to be expressed as ssDNA.
Users simply synthesize both sense and antisense oligonucleotides of desired
length and sequence (complimentary to each other) with Not 1 sites or Pac I /
Bam HI sites at both ends. The synthesized fragment is then cloned into the
plasmid with subsequent selection of proper orientation of sense and antisense
producing vectors ready for transfection experiments. Instruction, and sequence
maps are provided.
