Zonagen and Schering-Plough Report Status of Vasomax Regulatory Filings THE WOODLANDS, Texas and MADISON, N.J.--(BW HealthWire)-- May 10, 1999--Zonagen, Inc. (Nasdaq:ZONA - news; Pacific:ZNG) and Schering-Plough (NYSE:SGP - news) today announced that the companies have decided to forego a June FDA Advisory Panel review of the New Drug Application (NDA) for Vasomax® until the results of additional clinical studies being conducted by Schering-Plough can be submitted to the FDA. As a result of this decision, Zonagen expects that the FDA will issue a non-approvable letter for the NDA. Vasomax® is Zonagen's oral treatment for erectile dysfunction. ''Although we are disappointed with this delay, we believe that the additional data from Schering-Plough's studies are important to the long-term success of Vasomax®,'' said Joseph S. Podolski, president and chief executive officer of Zonagen. ''Since we began working together in November 1997, we have been impressed by Schering-Plough's ability to further clinical development and plan for the launch of Vasomax®. Based on this ability, we are confident that this strategy for Vasomax® will maximize our product's potential in the marketplace.'' Zonagen completed two positive pivotal clinical trials that form the basis of the NDA for Vasomax®. Zonagen and Schering-Plough believe that inclusion of the new data from the ongoing studies should enhance the regulatory filing and the commercial product profile for Vasomax®. Both companies are committed to obtaining approval of Vasomax with the optimal safety and efficacy product profile. Zonagen expects to submit the data to the FDA as an amendment to the NDA. It was not possible to extend the deadline for completion of the FDA review therefore it was decided to accept a non-approvable letter. Schering-Plough is continuing to seek regulatory approvals for Vasomax® in countries outside the United States, having launched the product in Mexico in June 1998 and in Brazil in April 1999. A regulatory application was filed in the United Kingdom in August 1998 as the first step in a mutual recognition procedure for the European Union. Zonagen Inc. is engaged in the development of pharmaceutical products for the reproductive system, including sexual dysfunction, urology, contraception and infertility. Schering-Plough Corporation is a research-based company engaged in the discovery, development, manufacturing and marketing of pharmaceutical products worldwide.
