             LIGAND PHARMACEUTICALS ANNOUNCES SECOND QUARTER RESULTS

             CONFERENCE CALL BEGINS AT 4:30 P.M. EASTERN TIME TODAY

SAN DIEGO (AUGUST 8, 2007) - LIGAND PHARMACEUTICALS INCORPORATED (NASDAQ: LGND)
(the "Company" or "Ligand") today announced financial results for the three
months ended June 30, 2007 and provided a business update.

SECOND QUARTER RESULTS
         The Company sold its commercial oncology product line in October 2006
and sold the AVINZA(R) product line in February 2007. The results of operations
related to these products have been reflected as discontinued operations for all
reporting periods discussed below.
         Total revenues for the second quarter of 2007 were $1.4 million,
compared with $1.1 million for the second quarter of 2006. Royalty revenues for
the 2007 second quarter were $1.4 million, compared with none for the 2006
second quarter. Collaborative research and development and other revenues for
the second quarter of 2007 were none, compared with $1.1 million in the second
quarter of 2006.
         Operating costs and expenses for the second quarter of 2007 were $16.3
million, compared with $19.1 million for the same 2006 period. The decrease was
due primarily to the reduction in headcount as a result of our restructuring
during the 2007 first quarter. Operating costs and expenses for the second
quarter of 2007 include $0.5 million of share-based compensation expense,
compared with $1.2 million for the same 2006 period. The loss from continuing
operations for the second quarter of 2007 was $7.7 million, or $0.08 per share,
compared with a loss from continuing operations of $17.2 million, or $0.22 per
share, for the second quarter of 2006. Income from discontinued operations in
the second quarter of 2007 was $7.9 million, or $0.08 per diluted share,
compared with $1.2 million, or $0.02 per diluted share, in the comparable 2006
quarter.
         Net income for the second quarter of 2007 was $0.2 million, or $0.00
per diluted share, compared with a net loss of $16.0 million, or $0.20 per
share, in the second quarter of 2006.
         As of June 30, 2007, Ligand had cash, cash equivalents, short-term
investments and restricted investments of $117 million. In addition, there is
approximately $35 million of cash held in escrow and trust accounts to support
potential indemnifiable claims by purchasers of our commercial products and
certain current and former members of our Board of Directors. In April 2007 the
Company paid a cash dividend of $2.50 per share for a total of $252.7 million.
In March 2007, the Company's Board of Directors authorized up to $100 million in
share repurchases. As of June 30, 2007, the Company had repurchased 3.8 million
shares for a total of $25.4 million.
         "We face an active and exciting second half of 2007, with both
partnered products and proprietary programs," said John L. Higgins, President
and Chief Executive Officer of Ligand Pharmaceuticals. "By the end of the year,
we may see an NDA filing for treatment of short-term ITP from GlaxoSmithKline
for eltrombopag (Promacta), FDA approval for Wyeth's bazedoxifene (Viviant), two
NDA filings with this product alone or in combination with conjugated estrogen
(Aprela) by Wyeth for other indications, and an NDA filing by Pfizer for
lasofoxifene (Oporia). We also expect to complete the Phase I study with
LGD-4665 and present preclinical data on LGD-3303.





" YEAR-TO-DATE RESULTS
         Total revenues for the six months ended June 30, 2007, were
$1.6 million, compared with $4.0 million for the first six months of 2006.
Royalty revenues for the six months ended June 30, 2007 were $1.4 million,
compared with none for the same period in 2006. Collaborative research and
development and other revenues for the first half of 2007 were $0.2 million,
compared with $4.0 million for the same period in 2006.
         Operating costs and expenses for the first six months of 2007 were
$46.0 million, compared with $36.3 million for the same period in 2006. The
increase was due to one-time expenses recognized in the first quarter of 2007
related to our restructuring. Operating costs and expenses for the six months
ended June 30, 2007, include $6.1 million of share-based compensation expense
compared with $2.0 million for the same period in 2006. The loss from continuing
operations for the first six months of 2007 was $24.6 million, or $0.24 per
share, compared with a loss from continuing operations of $30.9 million, or
$0.40 per share, for the first six months of 2006. Income from discontinued
operations for the first half of 2007 was $299.1 million, or $2.98 per diluted
share, compared with a loss from discontinued operations of $127.3 million, or
$1.63 per share, for the first half of 2006.
         Net income for the six months ended June 30, 2007, was $274.5 million,
or $2.74 per diluted share, compared with a net loss of $158.2 million, or $2.03
per share, for the same period in 2006.

PROGRAM UPDATE
         The Company also provided the following update on the status of its key
internal and partnered programs:
           o   LGD-4665 - TPO MIMETIC: Ligand continues to advance LGD-4665
               (small molecule,non-peptide TPO mimetic)through a Phase I
               dose-escalation study. In the second quarter we completed the
               single-dose escalation stage of the trial. In this study of
               healthy volunteers, the drug was safe and well tolerated. In
               addition to safety and dosing, the study is designed to measure
               platelet counts. Statistically significant elevated platelet
               counts were observed with single dose administration of LGD-4665.
               The multiple dose escalation stage of the trial is ongoing. The
               Company expects to complete the Phase I study by the end of 2007
               and is preparing to initiate multiple Phase II trials for
               different indications in the first half of 2008.

           o   GLAXOSMITHKLINE - TPO MIMETIC, ELTROMBOPAG: Ligand's partner
               GlaxoSmithKline reported Phase III data that confirmed increased
               platelet levels and significantly lowered incidence of bleeding
               in patients with ITP. Further, GlaxoSmithKline announced that an
               NDA filing for use in treatment of short-term ITP is expected by
               the end of 2007/early 2008.

           o   WYETH - SERM (SELECTIVE ESTROGEN RECEPTOR MODULATOR),
               BAZEDOXIFENE: Ligand's partner Wyeth announced that it received
               an approvable letter for bazedoxifene (Viviant) from the FDA in
               April 2007. Wyeth expects to receive FDA action for this product
               for osteoporosis prevention by the end of 2007. Bazedoxifene
               (Viviant) NDA filing for osteoporosis treatment is expected in
               the third quarter of 2007. Wyeth confirmed that it believes the
               NDA filing for bazedoxifene CE (Aprela) for menopausal symptoms
               and osteoporosis remains on track for the end of 2007. Wyeth also
               plans to file bazedoxifene (Viviant) for European review for
               treatment and prevention of osteoporosis in the third quarter.




           o   PFIZER - SERM, LASOFOXIFENE: Ligand's partner Pfizer announced
               plans to refile an NDA for lasofoxifene (Oporia) by the end of
               2007. Pfizer expects that the results from the PEARL
               (Postmenopausal Evaluation and Risk Reduction with Lasofoxifene)
               study will address the FDA's requirements in terms of safety and
               benefits for this product.

           o   TAP - SARM (SELECTIVE ANDROGEN RECEPTOR MODULATOR), LGD-2941:
               Ligand's partner TAP Pharmaceutical Products is continuing its
               Phase I trial with LGD-2941.

           o   LGD-3303 - SARM: Ligand is conducting preclinical studies to
               prepare LGD-3303 (SARM product candidate) for an IND filing and
               the initiation of clinical trials in 2008. Data from Ligand's
               study of the effect of LGD-3303 on bone density and strength in
               osteopenic rats will be presented at the American Society of
               Mineral and Bone Research in September 2007.
