>>Multiple late stage clinical trials of DCVax-L for GBM, our lead product, may be required before we can obtain regulatory approval.
Typically, companies conduct multiple late stage clinical trials of their product candidates before seeking product approval. Our current Phase III 348-patient clinical trial of DCVax-L for GBM is our first late stage trial. We may be required to conduct additional late stage trials with DCVax-L for GBM before we can obtain product approval. This would substantially delay our commercialization. In addition, our Phase III trial of DCVax-L is on a partial clinical hold for new screening for enrollment. We do not know what will happen with this partial hold. Although we have over 300 of the planned 348 patients already enrolled in this trial, and they have continued to be treated without interruption, we may not be released from the screening hold and may not be able to complete the planned enrollment in this trial.
There is also some possibility that changes requested by the FDA and/or other regulators could complicate the application process for product approval. In addition, a rapidly growing number of products are under development for brain cancer, including immunotherapies such as checkpoint inhibitor drugs and T cell based therapies, and some (e.g., NovoCure's device) have been approved in the U.S. It is possible that the standard of care for brain cancer could change while our Phase III trial is still under way. This could necessitate further clinical trials with our DCVax-L product candidate for brain cancer.
