                                                                    Exhibit 99.1

                      Enzon Reports First Quarter Results

    Pharmaceutical Writers/Business Editors/Biotech Writers

    BRIDGEWATER, N.J.--(BUSINESS WIRE)--Nov. 3, 2005--Enzon
Pharmaceuticals, Inc. (Nasdaq: ENZN) today announced its financial
results for the quarter ended September 30, 2005, the first quarter of
Enzon's six-month transition period ending on December 31, 2005. In
January 2005, Enzon announced a change in its fiscal year end from
June 30 to December 31.
    For the three months ended September 30, 2005, Enzon reported a
net loss of $5.8 million or $0.13 per diluted share. The Company's
financial results include investments related to the Company's ongoing
initiatives to reshape its business, including a $10.0 million charge
related to the previously announced acquisition of the rights to
recombinant human Mannose-binding Lectin (rhMBL).
    "Over the past several months, Enzon's senior leadership team has
rapidly advanced our goal of operating as a stronger, more focused
organization that is aligned on delivering long-term value," said
Jeffrey H. Buchalter, Enzon's chairman and chief executive officer.
"We have made significant progress toward overcoming the near-term
challenges we face, while simultaneously capitalizing on the intrinsic
strengths that exist at Enzon today. Recent strides include refocusing
our research and development investments, including acquiring the
exciting oncology opportunity rhMBL, and better supporting our
marketed brands through a number of new initiatives. We have also
further strengthened our research and development organization with
new leadership."

    The Company provided a summary of recent business developments,
including:

    --  In September 2005, the Company deepened the pharmaceutical
        expertise of its executive management team with the
        appointment of Dr. Ivan Horak to the position of executive
        vice president of Research and Development and chief
        scientific officer. Having held a number of senior medical and
        scientific positions in the pharmaceutical industry as well as
        the National Cancer Institute, Dr. Horak is a long-standing
        leader in the oncology community and brings an impressive
        background in drug development to Enzon.

    --  In September 2005, Enzon advanced its objective of
        strengthening its product pipeline with promising clinical
        development opportunities by acquiring exclusive worldwide
        rights, excluding the Nordic countries, for the development,
        manufacture, and marketing of rhMBL from the Danish biotech
        company NatImmune A/S. Mannose-binding Lectin (MBL) is a
        naturally occurring human plasma protein that plays a key role
        in the immune system's first-line defense against infections.
        This program represents an exciting opportunity for Enzon to
        offer a clinical benefit to cancer patients undergoing
        chemotherapy who are MBL-deficient and susceptible to serious
        infections.

    --  In line with its commitment to drive growth by investing in
        its marketed brands, Enzon recently amended its agreement with
        members of the Sanofi-Aventis Group for its oncology product,
        ONCASPAR(R) (pegaspargase). The amendment, which will become
        effective in January 2006, includes a significant reduction in
        Enzon's royalty rate. The Company believes there is a strong
        growth opportunity for ONCASPAR and it is committed to
        investing in programs designed to optimize that potential.

    Mr. Buchalter commented further, "Looking ahead, we have defined a
clear set of priorities for the remainder of 2005 and 2006. We will
continue to focus our resources on five key strategic areas: growing
our top line and investing in our commercial operations;
reestablishing Enzon as a scientific leader in PEGylation; rebuilding
our research and development pipeline; maximizing the return on our
asset base; and establishing a high-performance, value-focused
culture. We remain confident in the opportunities we see in each of
these areas to build a stronger Enzon that is capable of delivering
solid growth and increased value over the long term."

    Financial Results

    For the three months ended September 30, 2005, Enzon reported a
net loss of $5.8 million or $0.13 per diluted share, as compared to a
net loss of $0.9 million or $0.02 per diluted share for the three
months ended September 30, 2004. Enzon's financial results for the
three months ended September 30, 2005, include investments related to
the Company's ongoing initiatives to reshape its business for the
future, including the $10.0 million charge for in-process research and
development related to its acquisition of rhMBL. Additionally,
financial results for the quarter ended September 30, 2005 were
negatively impacted by a decline in product sales associated with its
intravenous antifungal product ABELCET. The Company's financial
results for the quarter ended September 30, 2005 were favorably
impacted by increased sales of Enzon's other marketed products, ADAGEN
and ONCASPAR, increased royalties related to Schering-Plough's
PEG-INTRON and Eyetech's MACUGEN, and the timing of expenditures
related to internal research and development programs and sales and
marketing initiatives.

    A summary of financial highlights for the quarter ended September
30, 2005 include:

    --  North American ABELCET sales for the three months ended
        September 30, 2005, were $11.1 million, as compared to $16.5
        million for the three months ended September 30, 2004. The
        decline from the prior year is due to competitive market
        conditions in the intravenous antifungal market, as previously
        reported by the Company.

    --  Combined sales of ONCASPAR, ADAGEN, and DEPOCYT were $14.1
        million for the three months ended September 30, 2005, versus
        $11.0 million for the three months ended September 30, 2004.
        The increase was primarily attributable to growth in sales of
        ADAGEN and ONCASPAR.

    --  Royalties of $15.2 million for the three months ended
        September 30, 2005, as compared to $10.1 million for the three
        months ended September 30, 2004, a 50% increase driven by
        Schering-Plough's December 2004 launch of PEG-INTRON
        combination therapy in Japan, and to a lesser extent the
        January 2005 launch of MACUGEN(R) in the U.S.

    --  $228.7 million in total cash reserves, which include cash,
        cash equivalents, short-term investments, and marketable
        securities, as of September 30, 2005, compared to $225.1
        million as of June 30, 2005. The increase in cash reserves for
        the three months ended September 30, 2005 is due to proceeds
        from the sale of an equity-based investment partially offset
        by cash used in operating activities and capital expenditures.

    Adjusted Financial Results

    On an adjusted basis, the Company reported an adjusted net loss of
$2.3 million or $0.05 per diluted share for the three months ended
September 30, 2005, versus an adjusted net loss of $0.1 million or
breakeven on a diluted per share basis for the three months ended
September 30, 2004. Enzon's adjusted financial results for the
three-month periods ended September 30, 2005 and 2004 exclude
non-operating expenses related to an equity investment in NPS
Pharmaceuticals Inc. common stock and a financial instrument that the
Company formed to reduce its investment risk associated with such
investment, as these expenses are outside of the Company's normal
course of business. The Company received the common stock under a June
2003 merger termination agreement with NPS. In August 2005, this
financial instrument expired and the Company received cash proceeds of
$7.5 million from the sale of its remaining shares of NPS common
stock.
    Enzon has reported adjusted financial results because the Company
believes they are representative of the underlying operations of its
business and are relevant to gaining an understanding of the Company's
trends and potential future performance. A table reconciling the
Company's adjusted financial results to its financial results
calculated in accordance with U.S. generally accepted accounting
principles (GAAP) for each of the three-month periods ended September
30, 2005 and 2004 has been included later in this release.

    Revenues

    Combined product sales for the Company's four internally marketed
products (ABELCET, ADAGEN, DEPOCYT, and ONCASPAR) decreased to $25.2
million for the three months ended September 30, 2005, compared to
$27.5 million for the three months ended September 30, 2004. The
decrease in product sales was attributable to a decline in North
American sales of the Company's intravenous antifungal product,
ABELCET. ABELCET sales were impacted by competitive conditions in the
intravenous antifungal market. For the three months ended September
30, 2005, North American sales of ABELCET were $11.1 million versus
$16.5 million for the three months ended September 30, 2004. Partially
offsetting the decrease in ABELCET sales were increased sales of
ADAGEN and ONCASPAR for the three months ended September 30, 2005, as
compared to the three months ended September 30, 2004.
    Sales of ADAGEN, an enzyme replacement therapy used to treat a
type of severe combined immunodeficiency disease, increased to $6.0
million for the three months ended September 30, 2005, as compared to
$4.3 million for the three months ended September 30, 2004.
    ONCASPAR sales grew to $5.8 million for the three months ended
September 30, 2005, as compared to $4.4 million for the three months
ended September 30, 2004. ONCAPSAR is a PEG-enhanced version of the
enzyme L-asparaginase used in combination with other chemotherapeutics
to treat acute lymphoblastic leukemia. Sales of DEPOCYT, a
sustained-release formulation of the chemotherapeutic agent cytarabine
arabinoside or ara-C used for the treatment of lymphomatous
meningitis, remained fairly consistent with the prior year, coming in
at $2.3 million for each of the three-month periods ended September
30, 2005 and 2004.
    In addition to product sales, Enzon's revenues also include
royalties on a number of products that utilize its proprietary
PEGylation technology, including Schering-Plough's PEG-INTRON.
Royalties increased to $15.2 million for the three months ended
September 30, 2005, as compared to $10.1 million for the three months
ended September 30, 2004. The increase in royalties was mainly driven
by higher sales of PEG-INTRON in Japan as a result of the December
2004 launch of PEG-INTRON combination therapy. In addition, the
increase in royalties was also attributable to the January 2005
introduction of Eyetech's MACUGEN(R) in the U.S. Under a 2002
agreement between Enzon and Nektar Therapeutics, Nektar provides
Eyetech with PEGylation technology for use in MACUGEN and the Company
receives a share of Nektar's royalties.

    Research and Development

    The Company's research and development expenses decreased to $5.3
million for the three months ended September 30, 2005, as compared to
$10.0 million for the three months ended September 30, 2004. This
decrease was attributable to the discontinuation of a number of
programs that did not meet the Company's criteria for continued
investment. Enzon is committed to investing in research and
development as it advances its objective of reshaping its business to
deliver long-term value, including reestablishing Enzon as a
scientific leader in PEGylation and rebuilding its development
pipeline.

    Selling, General and Administrative (SG&A)

    Selling, general and administrative expenses decreased to $11.7
million for the three months ended September 30, 2005, as compared to
$12.2 million for the three months ended September 30, 2004. The
decrease is largely due to the timing of investments in sales and
marketing programs. The Company remains committed to investing in new
sales, marketing, and other initiatives to further its objective of
reshaping its business to deliver long-term value, including improving
its top line performance and investing in its commercial operations.

    In-Process Research and Development

    In-process research and development was $10.0 million for the
three months ended September 30, 2005, due to the recognition of an
up-front payment payable in accordance with a license agreement that
the Company formed in September 2005 with the Danish biotech company,
NatImmune A/S. Under the agreement, Enzon obtained the exclusive
worldwide rights, excluding the Nordic countries, for the development,
manufacture, and marketing of rhMBL, a protein therapeutic under
development for the prevention of severe infections in MBL-deficient
individuals undergoing chemotherapy. In accordance with the agreement,
Enzon made an upfront payment of $10.0 million to NatImmune in October
2005.

    Net Other Expense:

    The Company reported $6.4 million in net other expense for the
three months ended September 30, 2005, as compared to net other
expense of $5.6 million for the three months ended September 30, 2004.
Net other expense for each of the three-month periods ended September
30, 2005 is comprised of investment income, interest expense, and
other non-operating expenses.
    Investment income increased to $1.6 million for the three months
ended September 30, 2005 from $0.8 million for the three months ended
September 30, 2004 due to an increase in interest rates and
interest-bearing investments.
    Interest expense remained relatively consistent coming in at $4.9
million for the three months ended September 30, 2005, as compared to
$5.0 million for the three months ended September 30, 2004. Interest
expense pertains to the Company's outstanding convertible subordinated
notes.
    Other non-operating expense for each of the three-month periods
ended September 30, 2005 and 2004 is primarily related to the NPS
common stock that the Company received under a June 2003 merger
termination agreement, as well as the financial instrument the Company
formed to reduce its exposure associated with such shares, as
discussed earlier in this release. Other expense was $3.1 million for
the three months ended September 30, 2005 versus $1.4 million for the
three months ended September 30, 2004 primarily due to changes in the
fair value of the common stock and financial instrument. In August
2005, the Company sold its remaining 375,000 shares of NPS common
stock and the financial instrument matured.

    Cash and Investments

    The Company's total cash reserves, which include cash, cash
equivalents, short-term investments, and marketable securities,
totaled $228.7 million as of September 30, 2005 compared to $225.1
million as of June 30, 2005. This increase was attributable to cash
proceeds of $7.5 million received during the three months ended
September 30, 2005 from the sale of 375,000 shares of NPS common
stock, received as part of a June 2003 merger termination agreement
discussed earlier in this release. The increase was offset in part by
cash used in operating activities and capital expenditures for the
three months ended September 30, 2005.

    Reconciliation of GAAP net loss to adjusted net loss

    The following table reconciles the Company's GAAP net loss and net
loss per diluted share to its adjusted net loss and net loss per share
for the three months ended September 30, 2005 and 2004:

(1) The charges excluded from Enzon's adjusted financial results for
    the three months ended September 30, 2005 and 2004 have been
    discussed in greater detail earlier in this press release. For
    purposes of calculating the adjusted net loss and adjusted net
    loss per share for the three months ended September 30, 2005, the
    adjustments are not tax-effected based on the Company's full
    valuation allowance against its deferred tax assets. For purposes
    of calculating the Company's adjusted net loss and adjusted net
    loss per share for the three months ended September 30, 2004, the
    adjustments have been tax-effected using a tax rate of 40% based
    on the Company's estimated tax liability for the fiscal year ended
    June 30, 2005.

(2) Adjusted net loss and adjusted net loss per share, as Enzon
    defines them, may differ from similarly named measures used by
    other entities, and consequently, could be misleading unless all
    entities calculated and defined such items in the same manner.
