I think it’d be useful to review Intercytex’s actual timeline for completion of ICX-TRC. Since the procedure is injections plus waiting 3 months, you’d think they could get the trials done quickly. However there have been some delays – though we don’t know the reasons for them. Perhaps the DTI “robot” needed some fine-tuning? Who knows?
Regardless, here’s the timeline I can piece together:
October 2003: Began Phase I trials on 7 people.
December 2005 (or earlier in 2005): Finished Phase I trials on 7 people; results showed high safety and promising efficacy, with increased hairs in 5/7 clients.
September 2006: Began Phase IIa trials on 5-7 people, finished by at least September 2007; results showed relatively poor efficacy, with ICX-TRC failing to work in 3 people.
Summer 2007: Begin Phase IIb trials on 5-7 people (assuming people are injected 6-12 weeks before September 25th, as findings would suggest); results showed promising efficacy, with ICX-TRC working in all subjects to some extent.
Summer 2007: Begin Phase IIc trials on 8 people (recruitment began over the summer); results uncertain.
If you look at the following link you’ll see that Intercytex hoped to start Phase II by fall/winter of 2004: http://www.intercytex.com/icx/news/releases/pr2004/2004-05-06/
Why did they wait so long to inject people with ICX-TRC in Phase II?
