ITEM 5. OTHER EVENTS
Pfizer Inc., in order to meet Federal Trade Commission requirements
for its merger with Warner-Lambert Company, has agreed to grant all development
and marketing rights to OSI Pharmaceuticals, Inc. for CP-358,774 (OSI-774).
This compound, a potent, selective and orally active inhibitor of the epidermal
growth factor receptor, or EGFR, is the most advanced clinical development
candidate arising from the OSI/Pfizer cancer collaboration and is currently in
Phase II trials. The reason for the divestiture is the determination by the FTC
of an anti-trust issue in the emerging EGFR cancer market arising as a result
of the development by Warner-Lambert of an EGFR inhibitor that is currently in
early Phase I studies. The divestiture of CP-358,774 (OSI-774) through the
vehicle of the existing Pfizer/OSI collaboration presented the most expeditious
resolution of the anti-trust issue. Although the FTC's determination is
technically subject to a 30-day public notice period to be followed by final
approval, both OSI and Pfizer believe that such final approval is all but
certain. Pfizer and Warner-Lambert completed the merger immediately following
the FTC's announcement.
Under terms of the May 23, 2000 agreement with Pfizer, which became
effective upon issuance and publication of the FTC's order on June 19, 2000,
OSI will receive a royalty-free license to all rights for the further
development and commercialization of CP-358,774 (OSI-774). In order to minimize
any development delays and ensure a smooth transition, Pfizer will continue to
co-ordinate the ongoing Phase II trials in ovarian, head and neck and
non-small-cell lung cancer through a transition period of up to six months.
Pfizer will also provide OSI with its inventories of finished product, bulk
drug and production intermediates. Sufficient inventories are available to
complete an extensive clinical development program.
Because OSI will no longer have Pfizer as its collaborative partner in
the clinical development of CP-358,774 (OSI-774), OSI is taking appropriate
steps to increase its expertise and capacity in this area. OSI has appointed
Paul I. Nadler, M.D., of Nadler Pharma Associates, LLC, as Acting Vice President
of Medical Affairs on an interim basis, who will coordinate the first phase of
this program and is establishing working partnerships with appropriate Contract
Research Organizations (CROs). Dr. Nadler's medical training is in oncology and
clinical immunology, and he has over 23 years experience in clinical trials. He
has served as a clinical consultant to OSI since September 1999.
OSI intends to retain full ownership of CP-358,774 (OSI-774) through
advanced clinical development prior to seeking a marketing partnership with a
major pharmaceutical company. OSI does not have, and does not currently plan to
develop, its own marketing capability.
OSI anticipates a net investment of approximately $25,000,000 in
development of CP-358,774 (OSI-774) over the next several years. As a result of
OSI's recently concluded private placement, which raised gross proceeds of
$56,500,000, OSI's strategic plan has been focused on increasing investment in
its own drug development programs and seeking an opportunity to license rights
to a drug candidate from another company for development by OSI. This
pre-existing plan envisioned significant increases in OSI's cash burn rate over
the next several years, with a projected operating cash burn of approximately
$20-22 million/year for fiscal years 2001 and 2002. The CP-358,774 (OSI-774)
project supercedes the preceding
<PAGE> 3
goal for in-licensing a clinical development candidate from another company. OSI
has current cash reserves of over $83 million and anticipates an operating cash
burn of up to $12,000,000 for fiscal year 2000. Although as a result of the
acquisition of CP-358,774 (OSI-774), the cash burn may now increase to as much
as $22-24 million for fiscal year 2001, OSI does not intend to cut any existing
programs.
TRIAL RESULTS TO DATE
Phase I safety studies for CP-358,774 (OSI-774) have demonstrated that
CP-358,774 (OSI-774) is well tolerated and revealed a reversible rash and mild
to moderate diarrhea, treated effectively with Loperamide (Imodium(R)), as side
effects from a 150 mg daily dosing regimen. A sub-set of patients in both Phase
I and II studies have now received daily doses of CP-358,774 (OSI-774) for
extended periods (from six months to over a year) and over 100 patients have now
received the drug with well managed side effects.
Enrollment has been completed for a 30 patient single agent open label
salvage study in ovarian cancer and approximately 45 patients in non-small cell
lung cancer and is ongoing for a similar study involving 100 patients in head
and neck cancer. Patients in these studies have advanced cancer and have failed
standard treatment regimens. Data continues to indicate that this drug is well
tolerated and there have been encouraging indications of activity, including
clinical responses, consistent with expectations based upon the experience of
competitor compounds.
COMPETITION
OSI is aware of three companies, two of whom with resources
substantially larger than OSI, who are currently developing drugs similar to
CP-358,774 (OSI-774). AstraZeneca PLC is developing a small molecule with a
close structural relationship to CP-358,774 (OSI-774) called Iressa(TM) that is
currently in Phase III trials. The Pfizer/Warner-Lambert compound, CI-1033, now
in Phase I trials, is an oral quinazolin like Iressa(TM) but, unlike these, is a
"suicide inhibitor" which chemically reacts with a target protein and is less
selective against other tyrosine kinases. Imclone Systems Incorporated is
developing a different kind of product, a humanized antibody, against the EGFR
target that is also in Phase III trials. AstraZeneca and Imclone have both
indicated an expectation that they will enter the market in early 2002, ahead of
the projected date for CP-358,774 (OSI-774).
