Abgenix and Immunex to Initiate Phase 2 Clinical Trial Of ABX-EGF in Kidney Cancer

    FREMONT, Calif. and SEATTLE, April 18 /PRNewswire/ -- Abgenix, Inc.
(Nasdaq: ABGX) and Immunex Corporation (Nasdaq: IMNX) announced today that the
companies will start a Phase 2 clinical trial of ABX-EGF in patients with
kidney cancer.  The Phase 2 trial will assess the tolerability and efficacy of
ABX-EGF as monotherapy (without concomitant chemotherapy) in patients with
kidney cancer.  ABX-EGF is being developed jointly by Abgenix and Immunex.
Initiation of this study triggers a milestone payment from Immunex to Abgenix.
    This multi-center, multiple-dose study will enroll up to 80 patients
across North America.  Patients will receive eight weekly intravenous
infusions at varying doses of ABX-EGF.  Preliminary results from an ongoing
Phase 1 study support the dose-escalating Phase 2 study protocol in kidney
cancer.
    "We are happy to be moving forward with the first of several Phase 2
trials for ABX-EGF, our lead oncology antibody therapy in development," stated
R. Scott Greer, chairman and chief executive officer of Abgenix.  "In the
coming months, Abgenix and Immunex will initiate a series of Phase 2 clinical
trials to explore the tolerability and efficacy of ABX-EGF in additional
cancer indications.  Our hope is to provide effective, antibody-based
therapeutic options for cancer patients."
    "We are encouraged by the preliminary results we are seeing in the Phase 1
trial for ABX-EGF," said Douglas Williams, Ph.D., Immunex executive vice
president and chief technology officer.  "The potential ability of ABX-EGF to
target the EGF receptor is an exciting approach in cancer research, making it
a valuable addition to the Immunex arsenal of oncology molecules."
    Preliminary results of an ongoing Phase 1 clinical trial of ABX-EGF will
be presented at the American Society of Clinical Oncology (ASCO) annual
meeting in May 2001.

    About ABX-EGF
    ABX-EGF is a fully human monoclonal antibody that targets the epidermal
growth factor receptor (EGFr), which is over-expressed on a variety of cancers
including lung, breast, bladder, prostate, colorectal, kidney and head and
neck cancer.  It has been demonstrated that cancer cells can become dependent
on growth signals mediated through the EGFr for their survival.  In mouse
models, ABX-EGF monotherapy has been shown to both eradicate established human
tumors and block the growth of human tumors.
    Overexpression of the EGFr has been reported to occur in 70-90% of kidney
cancer tumors.  In 2000, there were approximately 12,000 deaths associated
with kidney cancer and approximately 31,000 new cases of kidney cancer in the
United States.  Renal cell carcinoma or kidney cancer is characterized by a
lack of early warning signs, which results in a high proportion of patients
being diagnosed with advanced disease.  In cases where localized kidney tumors
are detected at an early stage, surgery provides the only curative therapy.
Metastatic kidney cancer is highly resistant to systemic therapies.
Therapeutic options for patients with advanced kidney cancer are very limited.
    "There is an unmet medical need for new treatment options for patients
with kidney cancer," said Robert Figlin, M.D., Professor of Medicine and
Urology of the Johnsson Comprehensive Cancer Center at the UCLA School of
Medicine.  "ABX-EGF, as a fully human monoclonal antibody, represents a
promising therapeutic approach to solid tumors, and I am encouraged by its
potential application in kidney cancer."
    Abgenix is a biopharmaceutical company focused on the development and
commercialization of fully human monoclonal antibody therapies for a variety
