Shares of CytRx ( CYTR) were among the best-performing health-related stocks Monday, rising 15% after the biopharmaceutical company's Arimoclomol drug received fast-track status from the Food and Drug Administration.

The drug, which had already received orphan drug status in May 2005, will be used to treat amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig's disease. Last week, the company announced the initiation of a phase II trial of the drug. Patient identification is under way at several clinical trial sites, the company said. "We are delighted that the FDA has permitted us to begin this important clinical trial, and the fast track designation constitutes yet another significant milestone in our effort to help those suffering from this deadly neurodegenerative disease for which there is no effective treatment," the company said. Shares were trading up 13 cents to $1.01.

Analogic ( ALOG) rose 5% after the company posted fourth-quarter earnings that topped Wall Street forecasts. The company earned $4.3 million, or 31 cents a share, on sales of $102 million.

In addition to turning in earnings results, the company said that deficiencies in the controls and procedures related to software recognition at its Camtronics subsidiary continued to constitute a material weakness. "As a result of this material weakness at Camtronics, management has concluded that the company's internal control over financial reporting was not effective as of July 31, 2005, and expects that the company's independent registered public accounting firm will reach the same conclusion in its audit report on the company's internal control over financial reporting," Analogic said. The company said that it would continue to work on the deficiencies and remains confident that it will be able to resolve the issues by the end of fiscal 2006. Shares were trading up $2.29 to $50.80.
