I would imagine that if the Phase III trials outside the US start showing promise, GSK will bring their full resources to bear to get a US trial approved and moved through regulatory approval as soon as possible. I'm sure they need the US market to recoup their investment.
Completely agree.

I know this has been asked before, but i don't recall seeing anyone knowing the answer, but do we know what the FDA's plan is for skipping of other exons? Would the FDA require trial phases for all other exon skipping? Has this discussion happened with the FDA? If not, is there one scheduled?

Well I would personally still participate in the trial even if the toxicity issues are known. I know that managing the kidney and liver is still possible as compared to managing a body wide loss of muscle tissue.

 

A risk vs benefit case should alos be considered as compared to taking in isolation that the drug has toxicity issues.

Does anyone happen to know what the toxicity concern is with this drug? I've heard bits and pieces but am unclear whether the toxicity they refer to has to do with the actual mechanics of exon skipping (the fact this would be toxic in a healthy body) or some side effect they are seeing with the drug? Wasn't it shown in the phase 2 study that the drug was well tolerated, or was some toxicity demonstrated in higher dosages in a separate test?

I would do too...our regulatory agency however doesn't allow the start of trials...

Hoping this will change when some results from Phase 2 UK trial will surface.

In the countries where clinical trials are moving forward, does anyone know if there is an agreement with the pharma (GSK in this case) to allow trial participants to continue on the exon skipping meds AFTER completion of the trial?
