People telling you otherwise are not up-to-date on the changes under the 21st Century Cures Act. It will be much easier to get the drug prescribed for other cancers once it is approved both for off label use and for extending the label and they can use what is called real world data to get it and get insurance coverage not for off-label prescription as well as for extending the label.
It may not necessarily be immediate but NWBO will need to get up to meeting demand for GBM and other brain tumors. But the fact is, going forward under this new regime of regulation, law and guidance, it will be far easier to expand access to many patients with different kinds of cancer and get it covered by insurance with patient records and far more informal evidence, not necessarily clinical trials, and for a drug with low side effects and a relevant immune reaction potentially, getting the drug will be even easier than for more toxic drugs with serious or life threatening side-effects.
More likely however, they will focus on just meeting initial demand first.
Also, combination therapies are likely to be much easier to get through under the 21st Century Cures act, especially where both drugs have had an initial approval.
But I do not expect the market to understand this fully at this time because these new rules are only really just being initially implemented. It will take a while for the market to realize how much more liberal the rules have become and what impact that will have on drugs of all kinds but especially oncology drugs.
