Molecular Insight Pharmaceuticals, Inc. (NASDAQ: MIPI) today announced the financial results for the fourth quarter and year ended December 31, 2008. In a conference call scheduled for today at 10:00 a.m., Eastern Time, the Company will discuss in detail the financial results as well as the Clinical and Financial Milestones for 2009.

2008 Operating Highlights

Dr. John W. Babich, Chief Executive Officer, President and Chief Scientific Officer, commented, "As we exited 2008, we re-prioritized our product pipeline and target markets and reduced operating expenses to establish a firmer financial footing for the Company. During the year we reached several clinical milestones that increased the value of our programs and the product portfolio while reducing regulatory risks. We benefited from additional healthcare industry expertise provided by our new Board members, and from the clarity and depth that was added to the management team."

A Value-Driven Product Pipeline. Today, Molecular Insight is directing its resources on the development of clinical-stage candidates that address significant unmet needs in cardiology and oncology. Our prioritized product pipeline consists of: Zemiva for the rapid detection of cardiac ischemia in the emergency department setting; Trofex, for improved detection and staging of metastatic prostate cancer; Azedra and Onalta, which are innovative targeted radiotherapeutics for the treatment of refractory metastatic neuroendocrine cancers that affect both children and adults; and Solazed™, a novel targeted radiotherapeutic for the treatment of metastatic melanoma.

Milestones Reached. Several key clinical milestones were reached in 2008. In December 2008, we reported positive Phase 2 (BP-23) trial results for Zemiva. The results from our Phase 2 clinical study (BP-23) demonstrated that Zemiva offers a significant clinical benefit in the rapid diagnosis of the chest pain patient. A Zemiva scan when combined with the current standard of care improves diagnostic sensitivity for cardiac ischemia by more than 50% (p < 0.0001). This improvement was evident even in patients whose symptoms had subsided up to 30 hours prior to the Zemiva scan. Importantly, no myocardial infarctions or cardiac-associated deaths occurred in the month following discharge from the hospital in patients with a normal Zemiva scan.

Trofex entered the clinic in June 2008, and demonstrated the ability to detect metastases, in both soft tissue and bone, soon after the drug was administered in men with metastatic prostate cancer. The ability to rapidly detect metastatic disease in both soft tissue and bone is a true advance in prostate cancer imaging and should have significant impact on disease management and patient outcomes.

In June 2008, we defined the maximum tolerated dose of Azedra in adult patients with pheochromocytoma. This dose will be used in the upcoming pivotal Phase 2 trial. Early in 2009, the Federal Drug Administration granted a Special Protocol Assessment for Azedra, which establishes the path to approval and reduces our regulatory risk.

In May 2008, we began a maximum tolerated dose study of Azedra in children with high-risk neuroblastoma. The dose defined in this study will be used in the upcoming pivotal Phase 2b trial, which is anticipated to begin in the second half of 2009 pending FDA agreement on the final protocol design.

Cash Optimized. We continue to benefit from our cash-advantaged position that supports our aggressive development program. In the fourth quarter of 2008, we moved to optimize the use of our cash on hand by identifying operational efficiencies and implementing non-development program-related cost-cutting measures. We anticipate that these prudent actions will reduce our cash burn by 10 to 20 percent in 2009 and 2010, as compared to 2008, and provide us with the financial resources necessary to carry out our near-term development plans as we continue to enhance stockholder value.

Clarity, Depth Added to Management. In September, Molecular Insight strengthened its Board of Directors by electing four new members with considerable experience in helping build value in well-recognized pharmaceutical organizations. The new members are David R. Epstein (Novartis Oncology), Yvonne Greenstreet (GlaxoSmithKline), Joseph M. Limber (Prometheus Laboratories), and Anthony F. Martin (TMA Consultants). The Company also added clarity and depth to the executive team early in 2009. Anthony F. Martin, Ph.D., was elected non-executive Chairman of the Board. Dr. Martin has had substantial success in building life science companies and in helping them gain access to capital. Paul A. Looney was named Chief Operating Officer. Mr. Looney has served in senior executive capacities with several life science and technology companies and has extensive experience in managing and advancing development-stage pharmaceutical and biotech companies and will be responsible for day-to-day operations. John W. Babich, Ph.D. was elected Chief Executive Officer and will continue as President and Chief Scientific Officer focusing on strategic initiatives.

Dr. Babich noted, "We have made substantial progress in our clinical development programs. We have seen successful completion of several trials that increased the value of not only these development programs, but the portfolio as a whole -- all while reducing regulatory risks. The organization is keenly focused on our key objectives for the coming year with a strong sense of commitment and urgency. Therefore, we are well positioned to achieve the upcoming milestones for both 2009 and 2010 that will create significant stockholder value."

2009 Clinical Milestones

--  Zemiva: Reach Agreement with FDA on Phase 3 Protocol Design
    
    The results from our Phase 2 clinical study (BP-23) demonstrated that
    Zemiva offers a significant clinical benefit in the rapid diagnosis of the
    chest pain patient.  A Zemiva scan significantly improved the ability to
    diagnosis cardiac ischemia when added to the current battery of tests that
    make up the standard of care in the Emergency Department setting. Zemiva
    consistently demonstrated this improvement in detection even in patients
    whose symptoms had subsided up to 30 hours prior to the scan.
    
    Based on our recent meeting with the FDA, we believe the requirements of
    Phase 2 development have been met and that a single robust Phase 3 trial
    will support Zemiva's registration.  We will continue to work with the FDA
    to reach agreement on a Phase 3 protocol and expect the Phase 3 trial to
    begin in early 2010.
    

--  Azedra: Received FDA Agreement on Special Protocol Assessment for
    Accelerated Approval for the Treatment of Malignant Pheochromocytoma in
    Adults
    --  Initiate Planned Pivotal Phase 2 Trial (IB-12b)
        The pivotal Phase 2 study (IB-12b) will be a single-arm trial
        conducted in 58 adults with pheochromocytoma.  The primary endpoint
        of the study will be the ability of Azedra to show a sustained
        improvement of severe hypertension, a prominent sign of
        pheochromocytoma due to the abnormal release of large amounts of
        hormones by the tumor.  Secondary endpoints will include
        demonstration of overall anti-tumor response, and the improvement
        in patients' daily functioning and performance including
        improvement in quality of life.  We anticipate the trial will begin
        in the second half of 2009 at approximately 15 sites including the
        US, Canada, and Europe.  If successful, Azedra would be the first
        anti-cancer therapy in the United States approved for the treatment
        of pheochromocytoma.

--  Azedra: Complete Phase 2a Maximum Tolerated Dose Study in
    Neuroblastoma in Children
    
    A Phase 2a dose-ranging and efficacy clinical trial in children with
    high-risk neuroblastoma is currently underway.  We expect this trial to be
    completed in the second half of 2009.  The optimal dose determined in this
    trial will be used in the subsequent pivotal Phase 2b trial.
    
--  Azedra: Obtain FDA Agreement on Special Protocol Assessment for
    Accelerated Approval for the Treatment of High-Risk Neuroblastoma in
    Children
    
    We are currently engaged in discussions with the FDA regarding the design
    of the pivotal Phase 2b trial to support approval for Azedra in relapsed
    neuroblastoma.  We anticipate that agreement will be reached in the second
    half of 2009.
    
--  Trofex: Complete Proof of Concept and Dosimetry Trial for the
    Detection and Staging of Metastatic Prostate Cancer; Complete Fast Track
    Development Pathway
    
    Based on our very encouraging initial results in men with prostate cancer,
    we will initiate studies to define the parameters for Phase 2 clinicals,
    such as the performance of Trofex in both normal men and men with
    metastatic disease.  In particular we will be comparing Trofex to other
    conventional imaging techniques to establish the regulatory strategy for
    the Phase 2 and Phase 3 programs.
    

Financial Highlights of the Fourth Quarter and Fiscal Year 2008

For the fourth quarter 2008, the Company reported a net loss of ($15.8) million or ($0.63) per share on a basic and diluted basis, compared to a net loss of ($21.6) million, or ($0.87) per share on a basic and diluted basis in the fourth quarter of 2007. Total revenue for the fourth quarter of 2008 was approximately $0.240 million compared to total revenue of approximately $0.150 million in the fourth quarter of 2007. The Company received funding under various Research and Development grants and this increase in revenue for the quarter is due primarily to the timing of grant-related activities.

Operating expenses for the fourth quarter reflected a 44% decrease from the same period of the previous year. Research and Development expenses, which represent 60% of total operating expenses, were $6.7 million for the quarter, as compared to $13.4 million for the same period last year. Key components of this 50% spending decrease were associated with the conclusion of the Zemiva trial and the timing of activity surrounding the Azedra clinical efforts. Operating expenses also included a 31% decrease in G&A expenses. G&A expenses were $4.2 million for the fourth quarter of 2008, compared to $6.2 million in the fourth quarter of the prior year. This decrease is due primarily to a reduction in legal fees and the use of consultants, and a workforce reduction. Other expense (net) was $5.1 million for the three months ended December 31, 2008, as compared to $2.2 million of other expense for the same three-month period in 2007. The increase in interest expense for the fourth quarter of 2008, compared to the fourth quarter of 2007, was due primarily to the $1.3 million payment-in-kind interest accrued on the Company's $150 million Senior Secured Floating Bonds.

For the twelve months ending December 31, 2008, the Company reported a net loss attributable to common stockholders of ($81.3) million or ($3.25) per share on a basic and diluted basis. This compares with a net loss of ($61.2) million for the same twelve-month period in 2007. Included in the net loss for the twelve months ending December 31, 2008 is revenue of approximately $0.5 million, which represents grant revenue from various Research and Development grants and compares with approximately $0.7 million, from the same source, during the period ended December 31, 2007.

Operating expenses for the twelve months ended December 31, 2008 increased by 6% to $62.4 million up from $58.4 million for the same period in the previous year. R&D expenses, which accounted for 62% of the Company's operating expenses for the twelve months ended December 31, 2008, decreased 5% to $38.7 million from $40.5 million in the same period last year. This decrease was due primarily to reduced manufacturing and clinical trial costs associated with the Zemiva program and reduced license fees for Onalta and Solazed. This decrease was offset by increases in clinical trial spending for the Azedra and Trofex programs and a compensation-related expense. The 32% increase in G&A to $23.7 million for the twelve months of 2008, as compared to $17.9 million for the same period in 2007 is attributable to stock-based compensation costs, severance costs related to employee terminations, and fees associated with the Company's compliance under Sarbanes Oxley. The increase in other expense (net) for the twelve months ended December 31, 2008 is attributable principally to the $18.3 million payment-in-kind interest accrued on the Company's $150 million Senior Secured Floating Bonds.

At December 31, 2008 the Company had approximately $105.8 million in cash, cash equivalents, and short-term and long-term investments which are invested in U.S. Treasury securities.
