             GTX, INC. REPORTS SECOND QUARTER 2005 FINANCIAL RESULTS

MEMPHIS, TENN. - July 28, 2005 -- GTx, Inc. (Nasdaq: GTXI), a biopharmaceutical
company dedicated to the discovery, development and commercialization of
therapeutics for cancer and other serious men's health conditions, today
reported financial results for the second quarter of 2005. The net loss for the
second quarter and six months ended June 30, 2005 was $10.0 million and $19.1
million, respectively, compared with a net loss of $4.5 million and $10.3
million for the same periods in 2004. At June 30, 2005, GTx had cash and cash
equivalents of $48.1 million.

"We continue to achieve our objectives for 2005," said Mitchell Steiner, M.D.,
CEO of GTx. "Both Phase III clinical trials of ACAPODENE for two separate
indications are enrolling on schedule. Our ostarine clinical trials are
advancing as planned. Ostarine is a SARM to which GTx holds exclusive rights and
is the second SARM developed by GTx to enter clinical trials. Next month we will
complete the Phase I multiple ascending dose clinical trial for ostarine and
will present scientific conclusions from this trial shortly thereafter.
Preparations for the ostarine Phase II trials are underway."

Revenues for the quarter and six months ended June 30, 2005 were $1.8 million
and $2.5 million, respectively, as compared to $1.1 million for the second
quarter and first six months of 2004. Revenues for 2005 included net sales of
FARESTON(R) (toremifene citrate 60 mg), marketed for the treatment of metastatic
breast cancer, and collaboration revenue from our partner, Ortho Biotech
Products, L.P., a subsidiary of Johnson & Johnson, for andarine, one of our
proprietary selective androgen receptor modulator (SARM) compounds. Revenues for
2004 consisted of collaboration revenue and reimbursement of development costs
from Ortho Biotech Products, L.P.

Research and development expenses for the second quarter and first six months of
2005 were $8.6 million and $16.0 million, respectively, compared to $4.2 million
and $8.6 million for the



same periods of 2004. The increase in research and development expenses was
primarily the result of the Company's continued investment in the following
clinical programs:

     o ACAPODENE(R) (toremifene citrate 20 mg) in a pivotal Phase III clinical
       trial for the prevention of prostate cancer in high risk men.

     o ACAPODENE(R) (toremifene citrate) 80 mg dose in a pivotal Phase III
       clinical trial for the treatment of serious side effects of androgen
       deprivation therapy for advanced prostate cancer.

     o Ostarine in Phase I single and multiple ascending dose clinical trials.
       Ostarine is being developed for andropause and other chronic wasting
       conditions related to aging. GTx retains the exclusive rights to
       ostarine, which is the second SARM that GTx has developed from
       discovery into clinical trials.

General and administrative expenses for the quarter and six months ended June
30, 2005 were $2.6 million and $5.2 million, respectively, compared to $1.6
million and $3.2 million for the same periods in 2004. The increases in both
periods primarily resulted from increased personnel costs to support the
Company's growth, higher insurance costs and increased patent costs and
professional fees.

SECOND QUARTER 2005 CORPORATE HIGHLIGHTS

     o The patient enrollment in both pivotal Phase III clinical trials of
       ACAPODENE for two separate indications is on schedule.

     o Presented the ACAPODENE Phase IIb clinical results for the prevention of
       prostate cancer in high risk men at the annual meeting of the American
       Society of Clinical Oncology and to the American Urological
       Association.

     o Initiated a second Phase I clinical trial evaluating multiple ascending
       doses of ostarine in healthy and elderly men.

     o Appointed Robert Karr, M.D. to the Board of Directors. Dr. Karr served as
       Senior Vice President, Strategic Management at Pfizer, Inc. and brings
       to GTx additional senior executive pharmaceutical industry knowledge
       and strategic experience in research and development.

ABOUT GTX

GTx is a biopharmaceutical company dedicated to the discovery, development and
commercialization of therapeutics primarily related to the treatment of cancer
and other serious men's health conditions. GTx's drug discovery and development
programs are focused on small molecules that selectively modulate the effects of
estrogens and androgens, two essential classes of hormones.

GTx has four clinical programs. The company is developing ACAPODENE(R)
(toremifene citrate 80 mg and 20 mg) for two separate indications in men: (1) a
pivotal Phase III clinical trial for the treatment of serious side effects of
androgen deprivation therapy for advanced prostate cancer, and (2) a pivotal
Phase III clinical trial for the prevention of prostate cancer in high risk men.
In its third clinical program, GTx and its partner, Ortho Biotech Products,
L.P., a subsidiary of Johnson & Johnson, are developing andarine, a SARM, for
cancer cachexia. In its fourth clinical program, GTx is developing its second
SARM, ostarine, for andropause and other chronic wasting conditions related to
aging, including frailty and sarcopenia. GTx maintains exclusive rights to
ostarine. GTx also has a marketed product, FARESTON(R) (toremifene citrate 60mg)
tablets, utilizing the same active pharmaceutical ingredient as ACAPODENE(R),
for the treatment



of metastatic breast cancer. In addition, GTx has an extensive preclinical
pipeline generated from its own discovery program which includes the specific
product candidates, prostarine, a SARM for benign prostatic hyperplasia (BPH),
and andromustine, an anticancer drug candidate, for hormone refractory prostate
cancer. Additional information can be found at the company's web site,

statements are based upon GTx's current expectations. Forward-looking statements
involve risks and uncertainties. GTx's actual results and the timing of events
could differ materially from those anticipated in such forward-looking
statements as a result of these risks and uncertainties, which include, without
limitation, risks that GTx will need substantial additional funding and may be
unable to raise capital when needed; GTx will not be able to achieve its
milestones within the time period indicated or at all; neither GTx nor its
partner will be able to commercialize its product candidates if preclinical

development and commercialization of its product candidates would be delayed;
use of third-party manufacturers may increase the risk that the Company will not
have adequate supplies of its product candidates; if third parties on whom the
Company relies do not perform as contractually required or expected, the Company
may not be able to obtain regulatory approval for or commercialize its product
candidates; the Company is dependent upon collaborative arrangements to complete
the development and commercialization of some of its product candidates, and
these collaborative arrangements may place the development of its product
candidates outside its control, may require it to relinquish important rights or
may otherwise be on terms unfavorable to the Company; and if the Company is not
