Millennium Exceeds Non-GAAP Profitability Goal and Narrows GAAP Net Loss by 78%(1)

Millennium Exceeds Non-GAAP Profitability Goal and Narrows GAAP Net Loss by 78%(1)

CAMBRIDGE, Mass., Feb. 8 /PRNewswire-FirstCall/ -- Millennium Pharmaceuticals, Inc. (NASDAQ: MLNM) today reported non-GAAP net income of $38.6 million for 2006, which marks the Company's first full year of non-GAAP profitability since becoming a fully integrated biopharmaceutical organization and exceeds the Company's financial guidance for 2006. This achievement represents a substantial improvement over the non-GAAP net loss of $87.2 million in 2005 primarily as a result of an increase in U.S. net sales of VELCADE(R) (bortezomib) for Injection, the market leader for the treatment of relapsed multiple myeloma, and lower expenses. GAAP net loss narrowed 78 percent to $44.0 million in 2006 from $198.2 million in 2005.

"In 2006, we continued to strengthen the business by driving VELCADE, advancing our clinical pipeline and bringing forward two new molecules from discovery to development, all while streamlining our infrastructure," said Deborah Dunsire, M.D., president and chief executive officer. "These moves align us with our vision of building an innovation-based company to continuously deliver medicines that fundamentally change the lives of patients with cancer and inflammatory diseases."

"Financially, we had an outstanding year in 2006 as we achieved the significant milestone of non-GAAP profitability and exceeded our bottom-line financial guidance for the fourth consecutive year," said Marsha Fanucci, chief financial officer. "As we enter 2007, we continue to position the Company for long-term growth by investing in VELCADE and our promising pipeline while continuing to focus on achieving our annual financial goals."

  2006 Financial Results
  - The Company achieved non-GAAP net income of $38.6 million. This result
    represents a significant improvement over the non-GAAP net loss of $87.2
    million in 2005 due primarily to:
    - A 15 percent increase in VELCADE U.S. net sales to $220.5 million,
    - An 18 percent decrease in combined non-GAAP research and development
      (R&D) expense and non-GAAP selling, general and administrative (SG&A)
      expense as a result of the Company's restructuring initiatives to
      focus investment on the key near-term growth drivers of the business,
      including VELCADE, the development pipeline and oncology discovery,
      and to reduce expenses. This reduction consists of:
      - A 14 percent decrease in non-GAAP R&D expense to $294.9 million
        (with the corresponding GAAP R&D expense, including stock-based
        compensation, of $318.2 million)(2) and
      - A 27 percent decrease in non-GAAP SG&A expense to $131.2 million
        (with the corresponding GAAP SG&A expense, including stock-based
        compensation and transaction costs associated with the AnorMED
        support agreement, of $155.6 million).(2)
  - The Company achieved GAAP net loss of $44.0 million, a substantial
    improvement over the GAAP net loss of $198.2 million for 2005
    primarily as a result of:
    - The increase in VELCADE U.S. net sales and
    - The decrease in operating expenses outlined above, as well as a
      $56.7 million reduction in restructuring charges resulting in $20.4
      million in 2006.
  - As of December 31, 2006, the Company had $894.3 million in cash, cash
    equivalents and marketable securities. The outstanding principal amount
    of convertible debt was $349.6 million of which $99.6 million is
    included in current liabilities.

  VELCADE Commercial Update

In the U.S., VELCADE is the market leader in the relapsed multiple myeloma setting, despite new competition, and has experienced unsolicited market-share growth in the front-line multiple myeloma setting. Outside of the U.S., VELCADE is marketed by Ortho Biotech Products, L.P., a member of the Johnson & Johnson Family Of Companies, and is approved in more than 75 countries. Ex- U.S. sales increased consistently throughout 2006 as a result of several new approvals and launches. In October 2006, VELCADE was approved for marketing in Japan for relapsed or refractory multiple myeloma in patients who have received at least one prior therapy. Millennium received an $8.0 million payment from Ortho Biotech for the achievement of this significant regulatory milestone. In addition, in the fourth quarter of 2006, VELCADE sales outside of the U.S. reached a pre-specified threshold which triggered a $25.0 million milestone payment from Ortho Biotech to Millennium.

In December 2006, the U.S. Food and Drug Administration (FDA) granted full approval of VELCADE for the treatment of patients with mantle cell lymphoma who have received at least one prior therapy. VELCADE is the first therapy to be approved by the FDA for the treatment of this disease. Mantle cell lymphoma is an aggressive form of non-Hodgkin's lymphoma (NHL) with a U.S. prevalence of 10,000 patients. The approval marks the first indication for VELCADE in NHL, the most common blood cancer.

In January 2007, the Company and Ortho Biotech Inc. launched their two- year U.S. co-promotion efforts, announced in October 2006, to jointly promote VELCADE for its approved indications. This arrangement is expected to increase the share of voice around the promotional and educational effort for VELCADE by leveraging the Ortho Biotech oncology sales force, which is one of the largest in the industry. Millennium will continue to be responsible for commercialization, manufacturing and distribution of VELCADE in the U.S.

VELCADE Clinical Update

In January 2007, the Intergroupe Francophone du Myelome (IFM) cooperative group completed the enrollment of 480 patients in the Phase III trial evaluating VELCADE in combination with dexamethasone compared to the vincristine, adriamycin and dexamethasone (VAD) triplet, a commonly used therapy, as induction therapy prior to stem cell transplantation in newly diagnosed multiple myeloma patients. The trial conducted by the IFM is part of a comprehensive Phase III program evaluating VELCADE in the treatment of newly diagnosed multiple myeloma patients in the transplant and non-transplant settings.

In December 2006, VELCADE was added to the updated National Comprehensive Cancer Network treatment protocol for newly diagnosed multiple myeloma patients. These practice guidelines are a benchmark for clinical policy in the oncology community.

At the 48th Annual Meeting of the American Society of Hematology (ASH) in December 2006, VELCADE was featured in over 150 abstracts, demonstrating significant and continued interest in the product by the hematology oncology community. The data further underscored the unparalleled strength of VELCADE as a single agent and demonstrated the product's power in combination with other agents with a well-characterized and predictable safety profile.

  - In relapsed multiple myeloma, VELCADE based combinations showed high
    response rates and improvement in time to disease progression.
    - Results from a randomized Phase III trial announced by Johnson &
      Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD) showed
      a statistically significant improvement in median time to progression
      (p < 0.0001) in patients receiving VELCADE in combination with
      DOXIL(R) (pegylated liposomal doxorubicin) compared to in patients
      receiving VELCADE alone. Ortho Biotech Products, L.P. announced on
      January 22, 2007 that the FDA accepted an application for priority
      review of DOXIL as combination therapy with VELCADE to treat patients
      with multiple myeloma who have received at least one prior therapy.
    - Results of Phase I and Phase II trials showed overall response rates
      as high as 93 percent and complete and near-complete response rates as
      high as 43 percent, some of the highest known response rates in this
      treatment setting.
  - In front-line multiple myeloma, VELCADE based combinations showed
    improvement in pre- and post-transplant outcomes.
    - Jean-Luc Harousseau, M.D., of Hospital Hotel-Dieu, Nantes, France
      presented preliminary data from the Phase III IFM trial showing that
      the VELCADE and dexamethasone combination achieved a complete and
      near-complete response rate of 20 percent, a greater than two-fold
      improvement over the complete and near-complete response rate produced
      by VAD. The preliminary investigator-assessed data also showed that
      the higher complete and near-complete response rate achieved by the
      VELCADE and dexamethasone combination potentially translated to
      improved post-transplant outcomes for patients.
    - Results of Phase II studies showed overall response rates as high as
      89 percent and very good partial response and complete response rates
      as high as 53 percent. This very good partial response and complete
      response rate improved to 79 percent following stem cell transplant.
  - As retreatment, VELCADE produced high response rates. VELCADE either as
    a single agent or in combination showed overall response rates (complete
    and partial responses) as high as 60 percent among patients who had an
    initial response to VELCADE treatment.
  - In the relapsed NHL setting, VELCADE based combinations demonstrated
    high response rates. Results showed overall response rates as high as 75
    percent across four subtypes of the disease (follicular, marginal zone,
    mantle cell lymphoma and T-cell lymphoma). These data include positive
    results from the Phase II study of VELCADE in combination with rituximab
    in follicular and marginal zone lymphoma which served as the basis for
    the Company-sponsored Phase III registration-enabling trial of once-
    weekly VELCADE plus rituximab versus rituximab alone.
  - Side effects observed in each of the VELCADE studies outlined above were
    similar to those seen in previous studies with VELCADE.

  Pipeline Update
  - MLN0415 - In January 2007, the Company initiated a Phase I multiple
    ascending dose trial of MLN0415, an oral, highly selective, small
    molecule inhibitor of IKKbeta which targets a key inflammatory pathway.
  - MLN0518 - In the fourth quarter of 2006, the National Cancer Institute
    (NCI) initiated Phase I/II trials of MLN0518, a RTK FLT-3, PDGF
    inhibitor, in prostate and renal cancers.
  - MLN3897 - Also in the fourth quarter of 2006, the Company initiated a
    randomized, double-blind, placebo-controlled Phase II study of MLN3897
    in patients with rheumatoid arthritis (RA). MLN3897 is an oral small
    molecule designed to block CCR1, a chemokine receptor believed to play a
    role in a number of inflammatory disorders. The multicenter study will
    assess the efficacy, safety and tolerability of MLN3897 in combination
    with methotrexate, a standard therapy for RA.

VELCADE is indicated for the treatment of patients with mantle cell lymphoma who have received at least one prior therapy. VELCADE is contraindicated in patients with hypersensitivity to bortezomib, boron, or mannitol. VELCADE should be administered under the supervision of a physician experienced in the use of antineoplastic therapy.

Risks associated with VELCADE therapy include new or worsening peripheral neuropathy, hypotension observed throughout therapy, cardiac and pulmonary disorders, gastrointestinal adverse events, thrombocytopenia, neutropenia and tumor lysis syndrome. Women of childbearing potential should avoid becoming pregnant while being treated with VELCADE. Cases of severe sensory and motor peripheral neuropathy have been reported. The long-term outcome of peripheral neuropathy has not been studied in mantle cell lymphoma. Acute development or exacerbation of congestive heart failure, and/or new onset of decreased left ventricular ejection fraction has been reported, including reports in patients with few or no risk factors for decreased left ventricular ejection fraction. There have been rare reports of acute diffuse infiltrative pulmonary disease of unknown etiology such as pneumonitis, interstitial pneumonia, lung infiltration and Acute Respiratory Distress Syndrome in patients receiving VELCADE. Some of these events have been fatal. A higher proportion of these events have been reported in Japan. There have been rare reports of RPLS in patients receiving VELCADE. RPLS is a rare, reversible, neurological disorder which can present with seizure, hypertension, headache, lethargy, confusion, blindness, and other visual and neurological disturbances. VELCADE is associated with thrombocytopenia and neutropenia. There have been reports of gastrointestinal and intracerebral hemorrhage in association with VELCADE. Transfusions may be considered. Complete blood counts (CBC) should be frequently monitored during treatment with VELCADE. Rare cases of acute liver failure have been reported in patients receiving multiple concomitant medications and with serious underlying medical conditions.

Safety Data: In 1163 patients in multiple myeloma and mantle cell lymphoma studies, the most commonly reported adverse events were asthenic conditions (64%), nausea (55%), diarrhea (52%), constipation (41%), peripheral neuropathy (39%), thrombocytopenia (36%), appetite decrease, including reports of anorexia (36%), pyrexia (34%), vomiting (33%) and anemia (29%). Twenty percent of patients reported at least one episode of grade 4 toxicity; the most common grade 4 toxicities were thrombocytopenia (5%) and neutropenia (3%).

This press release contains "forward-looking statements," including statements about the Company's growth, future operating results, discovery, development of products and strategic alliances. Various important risks may cause the Company's actual results to differ materially from the results indicated by these forward-looking statements, including: adverse results in its drug discovery and clinical development programs; failure to obtain patent protection for its discoveries; commercial limitations imposed by patents owned or controlled by third parties; the Company's dependence upon strategic alliance partners to develop and commercialize products and services based on its work; difficulties or delays in obtaining regulatory approvals to market products and services resulting from its development efforts; product withdrawals; competitive factors; difficulties or delays in manufacturing the Company's products; government and third-party reimbursement rates; the commercial success of VELCADE and INTEGRILIN(R) (eptifibatide) Injection; achieving revenue consistent with internal forecasts; and the requirement for substantial funding to conduct research and development and to expand commercialization activities. For a further list and description of the risks and uncertainties the Company faces, see the reports it has filed with the Securities and Exchange Commission. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

(1) Non-GAAP net income, non-GAAP profitability, non-GAAP research and development expenses and non-GAAP selling, general and administrative expenses are financial measures that are not prepared in accordance with U.S. generally accepted accounting principles (GAAP). Please see the Form 8-K furnished on February 8, 2007, by the Company to the Securities and Exchange Commission for a discussion of why the Company believes these non-GAAP measures are useful to investors and the additional purposes for which management uses these measures.

(2) The Company adopted Statement of Financial Accounting Standards No. 123R (SFAS 123R) as of January 1, 2006 and now records stock-based compensation expense in its statement of operations. Although this expense is a significant ongoing expense affecting the Company's results of operations, the Company excludes this charge from its non-GAAP R&D, non-GAAP SG&A, non- GAAP net income/(loss) because: (1) the Company's management excludes this expense from the Company's budget and planning process used to allocate resources in the Company's ongoing portfolio prioritization efforts, (2) the Company believes that excluding this expense could be helpful in comparing the Company's financial results to previous periods because stock-based compensation charges are excluded in the various operating expense categories and (3) as a result of varying available valuation methodologies, subjective assumptions and the variety of award types, the Company believes that excluding stock-based compensation may enable useful comparisons of the Company's operating results to its competitors. Non-GAAP net income/(loss) and other non-GAAP financial measures disclosed by the Company should not be considered in isolation or as a substitute for GAAP.

(3) GAAP net loss for 2007 includes amortization of intangibles of approximately $34 million in 2007, restructuring charges of between $15 million and $25 million in 2007 and stock-based compensation expense of between $30 million and $40 million. There could be additional charges excluded from the Company's GAAP net loss to arrive at non-GAAP net income and that are dependent on unknown future events and are difficult to predict and estimate at this time.
