"Company") issued a press release announcing the preliminary results of its
Phase III clinical trial, Study GL02-01, for its investigational lupus drug

density of women with systemic lupus erythematosus (SLE or lupus) receiving
glucocorticoids. The preliminary analysis indicated that the study failed to
meet its primary endpoint. The Company stated that it plans to continue its
analysis of the data from Study GL02-01 and will seek to meet with the U.S.

GENELABS ANNOUNCES PRELIMINARY RESULTS OF CLINICAL TRIAL GL02-01 IN WOMEN WITH
SYSTEMIC LUPUS ERYTHEMATOSUS

Study Fails to Meet Primary Endpoint


REDWOOD CITY, Calif. - October 5, 2004 - Genelabs Technologies, Inc.
(Nasdaq:GNLB) announced today that a preliminary analysis of its Phase III
clinical trial, Study GL02-01, for its investigational lupus drug Prestara(TM)
(prasterone) indicated that the study failed to meet its primary endpoint.
This double-blind, placebo controlled clinical trial was designed to measure
the effect of Prestara on the bone mineral density of women with systemic
lupus erythematosus (SLE or lupus) receiving glucocorticoids.

The company plans to continue its analysis of the data from Study GL02-01 and
will seek to meet with the U.S. Food and Drug Administration (FDA) to
determine its next steps.

"Although these preliminary results show that this study failed to reach
statistical significance, we are continuing to analyze the data in order to
gain further understanding of the results," stated James A.D. Smith, President
and Chief Executive Officer. "This process typically takes some time, and I
regret that we will likely not have further information to provide on Prestara
until we have completed these steps."

Genelabs previously completed a one-year Phase III clinical trial, designated
Study GL95-02, which included a nested study that indicated that the group of
patients receiving Prestara had increased bone mineral density, compared to a
decrease in bone density for the group of patients on placebo. Based on these
results, the FDA issued Genelabs an approvable letter, the key contingency of
which was a further clinical trial to confirm these results. Study GL02-01 was
designed to generate data to confirm the Study GL95-02 bone mineral density
results.
