Osteotech Inc. announced Tuesday that it has agreed to end acollaboration with Alza Corp. that was developing a sustained-release formulation of drugs to aid muscle and bone surgeries.
Alza (AMEX:AZA) is granted all rights to any products andtechnical information arising from the collaboration, which hadstarted in 1987, while Osteotech (NASDAQ:OSTE) is relieved ofmaking any further payments to Alza.
Bonnie Burdett, spokeswoman for Palo Alto, Calif.-based Alza,said the termination "has no impact on our earnings -- it was avery small program."
Osteotech said the companies have agreed that certain billingsfrom Alza will not be paid, resulting in a $670,000 one-timepre-tax benefit to the Shrewsbury, N.J., company in the firstquarter of 1992. Osteotech is now developing its own drug-delivery technology for use in musculoskeletal medicine. Thecollaboration had been working on Alza's bioerodable polymeras a delivery system for anti-infectives, said Burdett.
Alza's polymer is mixed with a drug and will break down in thebody over time, releasing the drug. An anti-infective agentwould be released at a surgical site after the wound was closed.
Osteotech is a processor of human bone and connective tissuefor use in transplants, and is developing tissue-relatedbiomaterials.
Alza lost 25 cents to close at $46.88. Osteotech dropped 50cents to $16. -- RF
