Alfacell Corporation Files for U.S. Orphan Drug Designation for ONCONASE(R)

BLOOMFIELD, N.J.--(HSMN NewsFeed)--Alfacell Corporation (Nasdaq: ACEL ), a biopharmaceutical company focused on the discovery, development and commercialization of novel ribonuclease therapeutics for cancer, today announced it has filed an application with the U.S. Food and Drug Administration (FDA) to obtain orphan designation for its lead drug candidate ONCONASE® (ranpirnase) for the treatment of patients with unresectable malignant mesothelioma (UMM). ONCONASE is currently being evaluated in a confirmatory Phase IIIb clinical trial in UMM.

The FDA orphan drug designation provides incentives to pharmaceutical and biotechnology companies to develop drugs for the treatment of diseases affecting fewer than 200,000 people in the United States. Unresectable malignant mesothelioma qualifies under this requirement, as about 4,000 new cases are reported in the U.S. each year.

If granted, orphan drug status will entitle ONCONASE to seven years of marketing exclusivity for the UMM indication after FDA approval. Other key benefits which Alfacell would be eligible for upon approval of the orphan drug application include protocol assistance by FDA in the preparation of a dossier that will meet regulatory requirements, tax credits, grant funding for research and development, and reduced filing fees for the marketing application.

Kuslima Shogen, Chief Executive Officer of Alfacell, said, "Orphan drug designation is an important tool for companies like Alfacell that are developing drugs for rare and emerging diseases. This is why we pursued and were granted orphan designation for ONCONASE for the mesothelioma indication in Europe and Australia. As such, we believe we are well-positioned with FDA for review of our application."

Shogen added, "With the U.S. orphan drug application filed and over 385 patients enrolled in the pivotal UMM study, we are continuing to make progress on the critical path leading to the anticipated completion of the NDA submission for ONCONASE, pending positive data, in mid-2007."


ONCONASE is a first-in-class therapeutic from Alfacell's proprietary ribonuclease (RNase) technology platform. ONCONASE has been shown in vitro and in vivo to target tumor cells while sparing normal cells. ONCONASE is internalized by endocytosis and released into the cytosol of the cancerous cell, where it selectively degrades tRNA beyond repair. In doing so, ONCONASE inhibits protein synthesis, stops cell cycle proliferation, and induces apoptosis (programmed cell death).

In addition to the ongoing confirmatory Phase IIIb registration study in malignant mesothelioma, the company is also conducting an ONCONASE Phase I / II trial in non-small cell lung cancer (NSCLC) and solid tumors.
