Exhibit 99.1


                  GENELABS REPORTS FINANCIAL RESULTS FOR THE
                     SECOND QUARTER AND FIRST HALF OF 2005

REDWOOD CITY, Calif. - August 10, 2005 - Genelabs Technologies, Inc.
(Nasdaq:GNLB) today reported revenues of $1.7 million and a net loss of $2.9
million, or $0.03 per share, for the second quarter of 2005. This compares to
revenues of $0.7 million and a net loss of $2.9 million, or $0.03 per share,
for the second quarter of 2004, which included a $2.0 million gain on the sale
of a discontinued operation. Revenues for the first half of 2005 were $3.4
million, and the net loss was $5.7 million, or $0.06 per share, compared to
revenues of $1.4 million and a net loss of $7.6 million, or $0.09 per share,
for the same period in 2004.

At June 30, 2005, Genelabs had $18.2 million in cash, cash equivalents and
restricted cash.

"The lower net loss through the second quarter of 2005 reflects lower research
and development costs following the completion of our Prestara Phase III
clinical trial in late 2004 and the higher contract revenue resulting from our
HCV drug discovery collaboration with Gilead Sciences, Inc." stated James A. D.
Smith, President and Chief Executive Officer. "In drug discovery, we recently
advanced a second non-nucleoside compound into preclinical development after it
satisfied all of our qualification criteria. This compound is a member of a new
chemical class our scientists discovered earlier this year, and we have begun
synthesizing and testing various compounds in this class. Results to date from
these tests show a number of these compounds to be very potent inhibitors of
the HCV repilcon with favorable metabolic and pharmacokinetic profiles. We are
quite excited about the prospects for our HCV programs and believe we have
developed world-class capabilities in this field."

"Turning to Prestara(TM), our investigational drug for lupus, all patient
visits are now complete in study GL03-01, which is a 12-month open-label study
following the 6-month double-blind trial for which top-line results were
announced in October 2004," continued Mr. Smith. "Data from the bone scans of
patients who participated in study GL03-01 were collected at an independent
central reading site, and we plan to commence our analysis of the results later
this month. We are also preparing for a meeting with the FDA to determine our
future development options for Prestara."

concentrating its capabilities on developing a late-stage product for lupus,
discovering novel compounds that selectively inhibit replication of the
hepatitis C virus and advancing preclinical development of compounds from this
hepatitis C virus drug discovery program. We believe that these high-risk,
potentially high reward programs focus our research and development expertise
in areas where we have the opportunity to generate either first-in-class or
best-in-class products that will address diseases for which current therapies
are inadequate. For more information, please visit www.genelabs.com.
