Economic Dependence Economic Dependence
We are economically dependent on our toll manufacturers. We primarily use one toll manufacturer in the U.S. to produce the clinical grade pelareorep required for our clinical trial program. Any significant disruption of the services provided by our primary toll manufacturer has the potential to delay the progress of our clinical trial program. We have used another toll manufacturer in the U.K. that has also produced clinical grade pelareorep at a smaller scale. We have attempted to mitigate this risk by producing sufficient pelareorep in advance of patient enrollment in a particular clinical trial.
