Was it poor planning, or the result of a flood or a fire on the Immunex production line? No. As badly as the company wants to bring more manufacturing space on line, it has been hobbled by a morass of FDA regulations that stretch months into years and prevent them from building new plants.

Because most small companies can't risk investing in a $300 million to $500 million manufacturing site years before their drugs pass regulatory muster, there are few facilities coming anytime soon. Contract manufacturers with outsourced production plants are full, and biotech companies with their own facilities are running at capacity. The result is a worldwide shortage in manufacturing space for monoclonal antibodies and long waiting lists for Enbrel.
