Myriad Pharmaceuticals to Acquire Javelin Pharmaceuticals

Creates Pipeline With Potential Near-Term Product Launch of Dyloject(TM) and Portfolio of Early-, Mid- and Late-Stage Drug Candidates in Cancer, HIV and Pain

Joint Conference Call Scheduled for 9:00 AM ET Friday, December 18, 2009

SALT LAKE CITY and CAMBRIDGE, Mass., Dec. 18, 2009 (HSMN NewsFeed) -- Myriad Pharmaceuticals (Nasdaq:MYRX ) today announced the company has entered into a definitive agreement to acquire Javelin Pharmaceuticals (NYSE Amex:JAV). The acquisition augments Myriad's portfolio of product candidates with Dyloject(TM) (diclofenac sodium for injection), a New Drug Application (NDA)-submitted candidate with the potential, based on its safety and efficacy profile, to become a valuable addition to hospital formularies as an injectable NSAID for the multimodal management of moderate-to-severe postoperative pain.

Under the Agreement and Plan of Merger, Myriad Pharmaceuticals will acquire all of the outstanding shares of Javelin common stock in exchange for Myriad Pharmaceuticals stock, resulting in the Javelin stockholders owning approximately 41% of the combined company immediately after the closing. The ownership interest of Javelin shareholders may increase up to a maximum of approximately 45% depending upon the timing of FDA approval of Javelin's lead drug candidate Dyloject. The transaction is expected to close in the first quarter of 2010. Concurrent with the closing of the transaction, Myriad Pharmaceuticals' board of directors may be expanded to eight members, including up to two members to be nominated by Javelin.

"We believe that this transaction represents a highly effective vehicle to unlock the long-term potential of Myriad Pharmaceuticals and near-term value of Javelin Pharmaceuticals," commented Adrian Hobden, Ph.D., President and Chief Executive Officer of Myriad Pharmaceuticals. "Myriad is well positioned to successfully launch Dyloject upon FDA approval by leveraging our financial resources and the expertise of our core commercial team. In turn, we believe that potential Dyloject revenue will support the development of our existing clinical stage drug candidates MPC-4326, Azixa, and MPC-3100."

Martin Driscoll, Chief Executive Officer of Javelin Pharmaceuticals, added, "This agreement creates a fully integrated biotechnology company with a submitted NDA for approval of a specialty care product, Dyloject, backed by significant financial resources, a broad pipeline for growth, and a seasoned management team for future commercialization efforts."

An NDA for Dyloject was submitted by Javelin on December 2, 2009. Dyloject is an injectable formulation of diclofenac. The development package includes data from two positive Phase 3 studies in postoperative abdominal and orthopedic pain together with safety data accrued from greater than 1,300 patients.

Diclofenac, a member of the class of drugs known as non-steroidal, anti-inflammatory drugs, or NSAIDs, is widely prescribed as an oral treatment for postoperative pain due to its combination of efficacy and tolerability. There remains an underserved medical need in the hospital setting for injectable NSAIDs that are safe, effective and fast-acting in patients unable to take oral medications. Effective use of injectable NSAIDs offers the potential to reduce opioid use and thereby accelerate patient recovery and shorten hospitalization. There is a growing demand for alternatives to opioids in the management of postoperative pain.

"Dyloject has demonstrated a very exciting profile in controlled studies showing statistically significant results in two registration trials, which have been submitted to the FDA for approval consideration earlier this month," said Ed Swabb, Chief Medical Officer of Myriad Pharmaceuticals. "If approved, Dyloject will be an important tool in the therapeutic armamentarium for multimodal management of postoperative pain."

Dyloject is approved and marketed in the United Kingdom by Therabel Pharma N.V. Myriad Pharmaceuticals will assume all rights to future milestone payments and royalties due from Therabel Pharma N.V.

About the Combined Pipeline

Myriad expects that, after commercial launch, Dyloject's revenues will help support development of Myriad's pipeline of promising clinical candidates, including:

* MPC-4326, a first-in-class small molecule inhibitor of HIV-1
maturation in Phase 2 studies for the oral treatment of HIV

* Azixa(TM), a Phase 2 drug candidate being developed for the
treatment of advanced primary and metastatic tumors; and

* MPC-3100, a fully synthetic, orally bioavailable inhibitor
of Hsp90 in Phase 1 testing for the treatment of cancer.

About Dyloject:

Dyloject is an injectable formulation of diclofenac with a submitted NDA awaiting filing by the FDA in the United States. Dyloject is already marketed in the United Kingdom. Diclofenac is a prescription NSAID that is widely prescribed to treat postoperative pain. Dyloject has the potential to provide an attractive alternative to other NSAIDs for the management of acute moderate-to-severe pain as a single agent, and to decrease the need for morphine or other opioids in this setting. There exists an underserved medical need for safe and effective injectable NSAIDs.

NSAIDs are widely used postoperatively with opioids, e.g., morphine, to reduce opioid requirements by 30-60% and thereby decrease opioid-related side effects. Combining different types of pain medicines (called "multimodal analgesia") is the most commonly advocated approach to acute postoperative pain management worldwide. Numerous studies of multimodal analgesia have shown that when patients are given an NSAID along with an opioid, dose requirements and adverse effects of the latter are reduced. Opioid side effects that are reduced by this dose-sparing approach include nausea, vomiting and inadequate breathing.

About MPC-4326:

MPC-4326 is being developed by Myriad Pharmaceuticals, Inc. for the oral treatment of HIV-1 infection. MPC-4326 is the first of a class of antiretroviral (ARV) drug candidates that inhibit HIV-1 replication by interfering with the maturation of the HIV-1 virus. Specifically, MPC-4326 interferes with the last step in the processing of the HIV-1 Gag protein. This inhibition leads to formation of noninfectious, immature virus particles, thus preventing subsequent rounds of HIV infection. As expected for a novel mechanism of action, MPC-4326 retains inhibitory activity against HIV-1 isolates resistant to the four classes of currently approved drugs commonly used by HIV infected patients: NRTIs, NNRTIs, protease inhibitors and fusion inhibitors. No cross-resistance has been observed.

Over 675 subjects, including over 180 HIV-infected individuals, have been studied in clinical trials of MPC-4326. Results from these trials have shown MPC-4326 to be well-tolerated and have demonstrated significant and clinically relevant reductions in viral load in a subset of HIV-infected patients representing approximately 60-70% of HIV-infected patients. This "responder" population can be identified by a simple, rapid and inexpensive assay of the HIV virus. In a Phase 2 clinical trial completed in 2008, MPC-4326 met its primary objective by demonstrating viral reduction in HIV-positive patients. In addition, the safety profile of MPC-4326 was comparable to earlier studies where that profile had been similar to placebo.

About Azixa (MPC-6827):

Azixa, MPI's most advanced cancer drug candidate, is being developed for the treatment of advanced cancers with brain involvement. Azixa is a novel small molecule that acts as a microtubule destabilizing agent, causing an arrest of cell division with subsequent programmed cell death, or apoptosis, in cancer cells. Several currently marketed clinically effective drugs share the identical mechanism of action. Importantly, however, Azixa has two unique, distinguishing characteristics. In non-clinical studies, Azixa has demonstrated the ability to effectively cross the blood-brain barrier and accumulate in the brain at levels as much as 3000% that in plasma. In addition, Azixa does not appear to be subject to multiple drug resistance (MDR) mechanisms.

Myriad Pharmaceuticals believes that Azixa represents a unique therapeutic opportunity with the potential to treat patients with any primary or secondary (metastatic) brain cancer or any cancer that has developed resistance to conventional chemotherapeutics. Azixa is currently in clinical studies in patients with glioblastoma multiforme and metastatic melanoma.

About MPC-3100:

MPC-3100 is currently in Phase 1 clinical studies. MPC-3100 is a novel, fully synthetic, orally bioavailable, small-molecule inhibitor of Heat shock protein 90 (Hsp90). Hsp90 is a proven target for cancer treatment. Early natural product inhibitors of Hsp90 demonstrated activity in several human cancer clinical studies, including studies of Her2+ breast cancer, multiple myeloma and gastric cancers. However, these compounds have also demonstrated significant toxicity. Unlike these molecules, MPC-3100 is a fully synthetic, small molecule that is orally bioavailable and has very encouraging non-clinical safety and efficacy data. MPC-3100 has the potential to treat a wide range of cancers.

Myriad Pharmaceuticals has an issued composition of matter patent on MPC-3100 and has developed a tablet formulation. These tablets are being used in the ongoing Phase 1 study. The trial has achieved drug levels in patients which are similar to efficacious levels obtained in non-clinical studies.

Heat shock protein 90 (Hsp90) is a chaperone protein that plays an important role in regulating the activity and function of numerous signaling proteins, or client proteins, that trigger and maintain proliferation of cancer cells. Important client proteins in cancer cells include steroid hormone receptors, protein kinases, mutant p53, and telomerase. Hsp90 binds and stabilizes these oncogenes while inhibition of Hsp90 leads to their degradation.
