Healthcare Industry News: NAPA-2
News Release - December 11, 2006
Nuvelo and Bayer Healthcare Announce Phase 3 Trials of Alfimeprase in Patients With Acute Peripheral Arterial Occlusion and Catheter Occlusion Did Not Meet Primary EndpointsSAN CARLOS, Calif., Dec. 11 (HSMN NewsFeed) -- Nuvelo, Inc. (Nasdaq: NUVO ) and Bayer HealthCare today announced top-line data demonstrating that the Phase 3 clinical trial of alfimeprase in acute peripheral arterial occlusion (PAO), known as NAPA-2 (Novel Arterial Perfusion with Alfimeprase-2), did not meet its primary endpoint of avoidance of open vascular surgery within 30 days of treatment. The companies also announced that the Phase 3 trial in catheter occlusion (CO), known as SONOMA-2 (Speedy Opening of Non-functional and Occluded catheters with Mini-dose Alfimeprase- 2), did not meet the endpoint of restoration of function at 15 minutes. These trials did not meet key secondary endpoints. In addition, the companies announced that they have temporarily suspended enrollment in the ongoing Phase 3 trials, NAPA-3 and SONOMA-3, until further analyses and discussions with outside experts and regulatory agencies are completed.
These data will be submitted for presentation at the next appropriate medical meetings.
"These outcomes are disappointing particularly for patients with acute PAO, who have few treatment options," said Dr. Ted W. Love, chairman and chief executive officer of Nuvelo. "We and our partner Bayer will conduct further analyses and have discussions with the Data Safety and Monitoring Board members, outside experts and regulatory authorities to determine how to proceed with the development of alfimeprase, including the possibility of alternative dosing and delivery."
NAPA-2 was a randomized, double-blind study that compared the efficacy and safety of 0.3 mg/kg of alfimeprase versus placebo in 300 patients worldwide. The study's primary endpoint was avoidance of open vascular surgery within 30 days of treatment. A variety of secondary endpoints were also evaluated, including restoration of arterial blood flow, safety endpoints such as the incidence of bleeding, and pharmacoeconomic endpoints such as length of hospital and intensive care unit stay.
SONOMA-2 was a randomized, double-blind trial comparing the efficacy and safety of 3 mg of alfimeprase with placebo in a 2:1 ratio in 303 patients with occluded central venous catheters. The study's primary endpoint was restoration of function to the occluded catheter in 15 minutes.
About the Collaboration
Nuvelo and Bayer HealthCare have a global collaboration for the development and commercialization of alfimeprase. Under the terms of the agreement, Bayer will commercialize alfimeprase in all territories outside the United States and will pay Nuvelo tiered royalties. Nuvelo retains commercialization rights in the United States and will remain the lead for the design and conduct of the global development programs.

Nuvelo, Inc. is dedicated to improving the lives of patients through the discovery, development and commercialization of novel drugs for acute cardiovascular and cancer therapy. Nuvelo's development pipeline includes three acute cardiovascular programs: alfimeprase, a direct-acting thrombolytic for the treatment of thrombotic-related disorders; rNAPc2, an anticoagulant that inhibits the factor VIIa and tissue factor protease complex that completed Phase 2 clinical development in acute coronary syndromes; and preclinical candidate NU172, a direct thrombin inhibitor for use as a short- acting anticoagulant during medical procedures. Nuvelo is also advancing an emerging oncology pipeline, which includes NU206 for the potential treatment of chemotherapy/radiation therapy-induced mucositis and inflammatory bowel disease, as well as rNAPc2 for potential use as a cancer therapy. In addition, Nuvelo expects to leverage its expertise in secreted proteins and cancer antibody discovery to further expand its pipeline and create additional partnering and licensing opportunities.
