            LIGAND REPORTS FINANCIAL RESULTS FOR FIRST QUARTER 2003:
    RECORD NET PRODUCT SALES UP 38% DRIVEN BY AVINZA CO-PROMOTION LAUNCH AND
                            SOLID ONCOLOGY REVENUES

  -- AVINZA NET SALES HIT NEW HIGH OF $6.6 MILLION, ONCOLOGY REVENUES GROW FOR
                          THIRD CONSECUTIVE QUARTER -

     SAN DIEGO, CA - APRIL 24, 2003 - Ligand Pharmaceuticals Incorporated
(Nasdaq: LGND) today reported total net product sales for the first quarter
ended March 31, 2003, of $18.9 million, compared to $13.7 million in the first
quarter of 2002, an increase of 38% driven by strong AVINZA(R) (morphine sulfate
extended-release capsules) sales of $6.6 million as part of its co-promotion
launch, and solid oncology revenues.

     Ligand's total revenues for the first quarter of 2003 were $23.1 million,
compared to $24.9 million for the same period in 2002, a decrease of 7%. The
decrease in quarterly revenues resulted from variances in other revenue
(primarily a $6 million royalty sale recorded in the first quarter of last year)
offsetting increases in product sales. Not including this royalty sale, total
revenues for the first quarter of 2003 increased 22%.

     Including a one-time, non-cash write-off of $5 million related to Ligand's
decision not to purchase X-Ceptor Therapeutics, net loss for the first quarter
was $20.3 million ($0.29 per share), compared to a net loss of $6.6 million
($0.10 per share) for the same period in 2002. Not including the one-time
charge, net loss for the first quarter was $15.3 million ($0.22 per share).

     "Ligand's first-quarter performance excluding one-time, non-cash charges
was ahead of our business plan goals, and is tracking on or ahead of our annual
financial guidance," said Paul V. Maier, Ligand's senior vice president and
chief financial officer. "We were particularly pleased with the 38% growth in
product sales, which was driven by a strong AVINZA quarter as part of our
co-promotion launch with Organon. Now that there are more than 800 sales
representatives in the field and we have the ability to achieve the No. 2 share
of voice in a growing, $2.8 billion market, we expect the second and third
quarters to reflect significant additional market share growth of AVINZA."




     In the first quarter of 2003, sales of individual products were:

- ------------------------------------------------ ----------------- ----------------


     It is important to note that Ligand's first quarter product sales from a
year ago were favorably affected by the initial stocking of wholesalers to
support commencement of ONTAK distribution in early 2002.

     Gross margin on product sales was 65% in the first quarter of 2003,
compared to 67% in the same period of 2002. Cost of products sold includes
approximately $2.8 million in non-cash expense primarily related to amortization
from the restructuring of the AVINZA license and supply agreement, and to ONTAK
technology amortization. Because the amounts of these quarterly, non-cash
expenses are fixed over AVINZA and ONTAK's patent lives, the products' gross
margins will continue to improve in 2003 as sales volumes increase.

     Collaborative research and development and other revenues were $4.2 million
in the first quarter of 2003, compared to $11.2 million in the same period of
2002. This decrease in revenues resulted primarily from the absence of $6
million in revenue from Royalty Pharma. In the first quarter of last year,
Royalty Pharma purchased from Ligand the right to receive a portion of potential
future sales of three selective estrogen receptor modulators (SERMs) now in
Phase III development. Royalty Pharma's next purchase options - each for $12.5
million - are exercisable in the third and fourth quarters of 2003. "Given the
timing of Royalty Pharma's options as well as potential product milestones, we
expect that unlike 2002, other revenues for 2003 will grow going forward, with
more than two-thirds occurring in the third and fourth quarters," Maier said.


                                       2



     Research and development expenses were $16.6 million in the first quarter
of 2003, in line with Ligand's annual financial outlook, compared to $13.1
million in the same period of 2002. The increase in R&D expenses resulted
primarily from accelerating patient accrual in the two pivotal Phase III studies
of Targretin capsules in non-small cell lung cancer. Enrollment of the 1,200
total patients required for the studies is now two-thirds complete and on track
to conclude this year. Enrollment of one study is expected to finish in the
third quarter, and the other in the fourth quarter.

     Selling, general and administrative expenses were $12.4 million in the
first quarter of 2003, compared to $9.7 million in the same period of 2002. The
increase in S,G&A expenses was due to the co-promotion launch of AVINZA, and to
an increase in medical marketing costs to expand use of ONTAK and Targretin.

     Loss from operations was $12.6 million in the first quarter of 2003,
compared to $2.3 million in the same period of 2002. Loss from operations is
expected to decrease substantially as product sales and other revenue continue
to grow.

     As of March 31, 2003, Ligand had cash, cash equivalents, short-term
investments and restricted cash of $44.7 million, compared to $74.9 million at
the end of 2002. In February 2003, Ligand completed its previously announced $20
million repurchase of approximately 2.2 million Ligand shares owned by Elan.
Ligand used $9.7 million of cash for operational activities in the first quarter
of 2003.

AVINZA UPDATE

     "Weekly AVINZA prescriptions continued to grow steadily in the first
quarter prior to initiation of full co-promotion with Organon," Maier said.
"Based on IMS NPA data, Ligand broke through 1,000 weekly prescriptions in the
first week of March, the last week our growing specialty pain sales force of
nearly 70 representatives promoted the product on their own. Since then, weekly
prescriptions have increased to 1,421, and this number reflects only one week of
co-promotion by Organon's 700-plus sales representatives. Increasing AVINZA
prescription demand and wholesaler re-stocking to support expanded co-promotion
resulted in strong quarterly sales of $6.6 million. In addition, we estimate
that as of February, AVINZA was stocked in approximately 6,000 retail
pharmacies, and our goal with Organon is to increase this to 15,000 pharmacies
in the second quarter by working with wholesalers, pharmacy chains, and hospital
and independent retail pharmacies."


                                       3



UPDATE ON IN-LINE ONCOLOGY PRODUCTS

     "For the third consecutive quarter, in-line oncology product sales
increased compared to the previous quarter, reflecting steadily increasing
end-user demand driven by our efforts to increase physician interest and expand
use of ONTAK and Targretin," Maier said. "Sales of ONTAK met or exceeded our
expectations in the first quarter of 2003. However, comparisons to the first
quarter of 2002 reflect the initiation a year ago of wholesale distribution of
the product."

     End-user demand for ONTAK and Targretin in the United States remained
strong in the first quarter of 2003. Unit shipments of ONTAK to end users
increased 18% compared to the first quarter of 2002.

     In the first two months of 2003, prescriptions for Targretin capsules
increased 34% compared to the same period of 2002, based on IMS data. European
distributor purchases of Targretin capsules were noteworthy in the quarter, and
demand is growing rapidly in the European Union, particularly Germany.

     In the first two months of 2003, prescriptions for Targretin gel increased
18% compared to the same period of 2002, based on IMS data.


RECENT LIGAND HIGHLIGHTS

o    ORGANON, LIGAND BEGIN FULL AVINZA CO-PROMOTION. Organon's hospital
     representatives and national accounts team began promoting AVINZA on March
     10. The company's primary care and specialty sales forces began promotion
     on April 7. In addition, Ligand is promoting AVINZA with its expanding
     specialty pain sales force of nearly 70 representatives. Organon and
     Ligand's combined sales force effort is approximately 12-fold greater than
     what Ligand alone could dedicate to the product.

o    LIGAND EARNS $1.5 MILLION MILESTONE PAYMENT AS LILLY ADVANCES LY818, FIRST
     IN A SERIES OF DISTINCT PPAR MODULATORS, INTO PHASE II STUDIES. LY818 is a
     novel, potent, oral, once-daily peroxisome proliferation activated receptor
     (PPAR) modulator for the treatment of type II diabetes and metabolic
     diseases. LY818 was discovered through the ongoing research collaboration
     between Lilly and Ligand. PPARs are a subfamily of intracellular receptors
     that regulate glucose and lipid homeostasis. They play a key role in
     enhancing cellular responses to insulin, and in fat tissue stores and
     metabolism.

o    LIGAND ELECTS NOT TO EXERCISE OPTION TO PURCHASE X-CEPTOR THERAPEUTICS.
     Ligand will continue to own approximately 17% of X-Ceptor's stock. Ligand
     has been a minority equity investor in X-Ceptor since 1999, when Ligand and
     a group of private investors formed the private company to further the
     development of orphan nuclear receptor technology to identify new drugs.
     Ligand decided not to purchase X-Ceptor in order to focus on its priorities
     for increasing shareholder value in 2003, such as accelerating revenue
     growth from AVINZA and the company's in-line oncology products, and
     completing patient enrollment in the pivotal Phase III studies of Targretin
     capsules in non-small cell lung cancer.

o    FOUR CLINICAL TRIALS PRESENTED AT AMERICAN ACADEMY OF DERMATOLOGY MEETING
     SHOW TARGRETIN, PANRETIN DEMONSTRATE PROMISING ACTIVITY IN RANGE OF
     DERMATOLOGIC DISORDERS. The studies indicated that activating retinoid X
     receptors plays a key role in treating hand dermatitis, psoriasis,
     cutaneous T-cell lymphoma and photoaging. In one 55-patient, randomized
     phase I/II study, nearly 40% of patients with chronic severe hand
     dermatitis who were treated with Targretin gel 1% experienced clinical
     improvement of 90% or more, and almost 80% of patients improved by at least
     50%. Ligand plans to begin a Phase II/III registration track program for
     Targretin gel this year.
