Cell Genesys Inc. said it will fire 25 employees, or about 20% of its work force, and reduce operating expenses by 30% as it concentrates on clinical testing of its gene therapies. Fremont-based Cell Genesys, which had revenue of $23.8 million last year, said it hopes to save about $10million annually from the job cuts and reductions in spending on laboratory studies. The company is trying to get its most promising treatments to the marketplace, including AIDS and cancer treatment therapies.
