                SciClone Reports Third Quarter Results

    SAN MATEO, Calif.--(BUSINESS WIRE)--Nov. 1, 2004--SciClone
Pharmaceuticals, Inc. (Nasdaq:SCLN) today reported results for the
third quarter and nine months ended September 30, 2004. Revenues from
sales of ZADAXIN(R), SciClone's lead product candidate, were
$5,753,000 for the third quarter and $16,780,000 for the nine months
ended September 30, 2004. Net loss for the third quarter 2004 was
$4,913,000, or $0.11 per share, and for the nine months ended
September 30, 2004 the net loss was $10,923,000, or $0.24 per share.
In addition, SciClone reported $134,000 in contract revenue for the
third quarter of 2004 and $1,497,000 for the nine months ended
September 30, 2004, which includes a $1,000,000 milestone payment
received from Sigma-Tau during the second quarter 2004. Contract
revenue was $224,000 for the third quarter of 2003 and $672,000 for
the nine months ended September 30, 2003.
    In comparison, revenues for the third quarter of 2003 were
$5,421,000 and $26,628,000 for the nine months ended September 30,
2003. The revenues for the nine months ended September 30, 2003
included approximately $11,000,000 due to the unanticipated temporary
increase in sales of ZADAXIN in response to the now abated SARS
epidemic in China. Net loss for the third quarter 2003 was $2,850,000,
or $0.07 per share, and net loss for the nine months ended September
30, 2003 was $588,000, or $0.02 per share.
    Research and development expenses were $4,858,000 for the third
quarter 2004, compared to $4,585,000 for the third quarter 2003.
Research and development expenses for the nine months ended September
30, 2004 totaled $13,552,000, compared to $12,676,000 incurred in the
nine months ended September 30, 2003. General and administrative
expenses for the third quarter 2004 were $2,573,000, compared to
$998,000 for the third quarter 2003. General and administrative
expenses for the nine months ended September 30, 2004 were $5,022,000,
compared to $3,045,000 incurred in the nine months ended September 30,
2003. The increase in general and administrative expenses is
attributable to a one-time expense incurred in connection with the
separation of the former Chief Executive Officer from the Company in
July 2004.
    Cash, cash equivalents and short-term investments totaled
$52,986,000 at September 30, 2004, compared to $54,970,000 at June 30,
2004 and $66,256,000 at September 30, 2003.
    "We remain focused on our primary objective of developing ZADAXIN
for the treatment of hepatitis C in the major pharmaceutical markets,"
commented Richard A. Waldron, SciClone's Chief Financial Officer. "In
addition, we are advancing the development of pegylated ZADAXIN and
our proprietary drug candidate SCV-07, a potential therapeutic to
treat viral and other infectious diseases."
    Alfred Rudolph, M.D., SciClone's Chief Operating Officer, added,
"Our U.S. phase 3 hepatitis C clinical trials are ongoing and on
target to be completed by the end of next year. We continue to make
progress with our other clinical development programs with a ZADAXIN
triple therapy hepatitis C trial planned by our European partner
Sigma-Tau and preclinical studies to support an IND filing in the
United States during the first half of 2005 for SCV-07."

    Financial outlook

    For the fiscal year 2004, SciClone is refining its guidance for
certain financial items. SciClone's estimate for net sales of ZADAXIN
remains unchanged and is expected to be slightly greater than $22
million. Research and development expenses for the year are now
anticipated to be between $19 and $20 million, instead of the previous
estimate of between $19 and $21 million. Net loss for 2004 is now
expected to be between $15 and $16 million, lower than the previous
estimate of between $15 and $17 million. Accordingly, net loss per
share for 2004 is now expected to be between $0.35 and $0.37 per
share, lower than the previous estimate of between $0.35 and $0.39 per
share. SciClone's guidance for cash, cash equivalents and short-term
investments at December 31, 2004 remains unchanged at between $45 and
$47 million.

    Recent Announcements

    --  SciClone today reported that ZADAXIN in a triple therapy,
        single-arm pilot trial in Mexico produced a sustained
        virologic response at week 72 (SVR) in 19% of difficult to
        treat hepatitis C patients, those who are non-responders
        infected with the genotype 1 strain of the virus. These
        results are more than twice the 9% SVR from a separate,
        unrelated trial treating genotype 1 non-responder patients
        with pegylated interferon and a similar dose and ribavirin but
        without ZADAXIN. Although this was a small, uncontrolled pilot
        trial and reliable conclusions cannot be drawn from
        comparisons of results of different studies, SciClone is
        encouraged by the results.

    --  SciClone today announced the appointment of Richard J. Hawkins
        to the company's Board of Directors as a non-executive member.
        Mr. Hawkins is a highly experienced executive with over 30
        years of experience in the pharmaceutical industry.

    The information in this press release contains forward-looking
statements including our expectations and beliefs regarding future
sales of our products, future financial results, research and
development expense levels, asset levels, timing of filing of our
Japanese New Drug Application, expectations regarding both of our
phase 3 hepatitis C clinical trials, and the fact that the
experimental or clinical data described may imply certain actual
results in human clinical trials or in larger patient populations.
Words such as "expects," "plans," "believe," "may," "will,"
"anticipated," "intended" and variations of these words or similar
expressions are intended to identify forward-looking statements. In
addition, any statements that refer to expectations, goals,
projections or other characterizations of future events or
circumstances, including any underlying assumptions, are
forward-looking statements. These statements are not guarantees of
future performance and are subject to risks, uncertainties and
assumptions that are difficult to predict. Therefore, our actual
results could differ materially and adversely from those expressed in
any forward-looking statements as a result of various factors,
including changes in demand for ZADAXIN, the progress or failure of
clinical trials, the statistical significance of data obtained from
clinical trials, the fact that results from small studies may not be
predictive of results from larger studies, maintenance of the
sufficiency and eligibility of the enrolled patient population,
unanticipated delays or additional expenses incurred during our
clinical trials, our future cash requirements, unexpected delays in
preparation of the Japanese New Drug Application, delays in analyzing
and synthesizing data obtained from clinical trials, future actions of
our strategic partners, unexpected delays in preparation for
enrollment, future actions by the U.S. Food and Drug Administration or
equivalent regulatory authorities in Europe and Japan and the fact
that experimental data and clinical results derived from studies with
a limited group of patients may not be predictive of the results of
larger studies, as well as other risks and uncertainties described in
SciClone's filings with the Securities and Exchange Commission.
