             GTX, INC. REPORTS SECOND QUARTER 2004 FINANCIAL RESULTS

MEMPHIS, Tenn - July 29, 2004--GTx, Inc. (Nasdaq: GTXI), a biopharmaceutical
company dedicated to the discovery, development and commercialization of
therapeutics for serious men's health conditions, today reported financial
results for the second quarter and six months ended June 30, 2004. The net loss
for the quarter and six-month period was $4.5 million and $10.3 million,
respectively, compared with a net loss of $3.5 million and $6.2 million for the
same periods in 2003.

"We are very pleased to report another positive quarter at GTx with significant
progress of our lead clinical program, ACAPODENE," said Mitchell Steiner, M.D.,
CEO of GTx. "We are focused on continuing the momentum in our clinical trials
for both ACAPODENE for prevention of prostate cancer and ACAPODENE for
supportive care of patients being treated for advanced prostate cancer. In
addition, our SARM program continues to progress successfully."

Revenue for both the second quarter and six months ended June 30, 2004 was $1.1
million, and resulted from the reimbursement of development costs and the
amortization of upfront fees. The revenue was associated with the Company's
collaboration and license agreement with Ortho Biotech Products L.P., a
subsidiary of Johnson & Johnson, for GTx's lead SARM compound, andarine.

Research and development expenses increased to $4.1 million for the second
quarter of 2004 from $2.6 million for the second quarter of 2003 and increased
to $8.5 million from $4.7 million for the first six months of 2004 as compared
to the same period in 2003. These increases reflect GTx's growing investment in
its lead clinical program for ACAPODENE(TM) (toremifene citrate) which includes
an ongoing pivotal Phase III clinical trial for the treatment of side effects of
androgen deprivation therapy (ADT) and a recently completed Phase IIb clinical
trial for the prevention of prostate cancer in high risk men with high grade
prostatic intraepithelial neoplasia (PIN). Increases in research and development
expenses also reflect continuing development of GTx's second clinical program,
andarine, and preclinical development of its other selective androgen receptor
modulator (SARM) compounds, including ostarine and andromustine.

General and administrative expenses increased during the quarter to $1.6 million
from $0.8 million for the second quarter of 2003 and increased to $3.2 million
for the first six months of 2004 from $1.4 million for the same period in 2003.
The increase primarily resulted from the addition of key personnel, increased
insurance costs and professional fees to support GTx's growth and its reporting
obligations as a public company.

At June 30, 2004, GTx had 24,656,923 shares of common stock outstanding, and
cash and cash equivalents of approximately $81.4 million.







Corporate Highlights

         o        On June 4, 2004, GTx announced positive Phase IIb clinical
                  trial results for its lead program ACAPODENE(TM). This is the
                  largest prospective study to determine the natural history of
                  patients with high grade PIN and the findings suggest that
                  ACAPODENE(TM) may be an effective agent in preventing prostate
                  cancer. Specifically, the trial demonstrated that
                  ACAPODENE(TM) 20mg can produce a clinically significant
                  reduction of prostate cancer cumulative risk over one year.
                  Patients treated with ACAPODENE(TM) 20mg had a lower incidence
                  of prostate cancer compared to placebo, 24.4% vs. 31.2%
                  respectively. The study also revealed that patients who were
                  treated with ACAPODENE(TM) for the entire 12 months had a 48%
                  reduction in prostate cancer incidence. Following discussions
                  with the Food and Drug Administration (FDA), GTx plans to
                  initiate a pivotal Phase III clinical trial to confirm these
                  positive findings.

         o        GTx entered into collaboration agreements with diagnostic labs
                  Hybritech, Inc., a wholly owned subsidiary of Beckman Coulter,
                  Inc. and diaDexus, Inc. GTx will provide clinical samples to
                  these diagnostic labs from its now completed Phase IIb
                  ACAPODENE(TM) trial. These collaborations are intended to
                  develop a commercial blood or urine test which could detect
                  high grade PIN in the millions of men who unknowingly harbor
                  this precancerous lesion of the prostate or who may develop
                  prostate cancer.

         o        At the 40th Annual Meeting of the American Society of Clinical
                  Oncology (ASCO), results were presented describing data from
                  GTx's Phase II clinical trial for the treatment of side
                  effects associated with ADT and data from a preclinical study
                  designed to demonstrate ACAPODENE's(TM) ability to prevent
                  bone loss as a result of ADT in rats. In addition,
                  presentations on GTx's SARM program were made at the Endocrine
                  Society Meeting and the National Chemistry Symposium.

         o        GTx announced the Urology Resident Research Fellowship
                  program, in partnership with the Department of Urology at the
                  University of Tennessee College of Medicine. This program will
                  allow urology residents from the University of Tennessee to
                  spend a research rotation at the GTx research laboratories.
                  This program underscores GTx's commitment to the continued
                  development of drugs to treat serious men's health conditions.
                  By exposing these residents to our scientists and clinicians,
                  we are helping to develop well-rounded urologists who will not
                  only contribute to cutting-edge research during their time in
                  the GTx labs, but will also be better able to treat their
                  patients as they enter their own practices.
