Mate - they have gone from no chance to stable, i.e. no worsening of their tumours. This within the constraints of the dosage regimen. Great result, even if I may have emotional ties to this result.
The biggest concern to me is moving the trials to Australia. I may have read it wrong, but I hope there is continuing treatment of those patients in the US so that further data is generated on disease control or otherwise.
Having said that I dipped my toe in the water today, having watched for a year, as I believe there is significant medical benefit with these drugs.
The other concern is manufacturing for PTX-100. I'm sure they can overcome that, but having been in the industry at that stage, I know that it will take time. If there are further good results on PTX-100 & PTX-200 maybe the time for big Pharma to jump in.
