Guest guest Posted May 25, 2002 Report Share Posted May 25, 2002 It seems as though my opening myself up to questions has only served to foster strong, heated debate amongst me and others and yourselves. For that I am truly sorry. This all began with an innocent e-mail message to me that I replied to concerning details of our clinical study. I DID NOT POST THE STUDY NOR DID I LEAK THE DOCUMENT IN THE FIRST PLACE. I have never once suggested that our study was flawed- as someone else has put it on the board. Furthermore, to suggest that our science is poor without seeing all of the exhaustive in vitro cell culture work (5 skin cell types stimulated with four separate inflammatory inducers and investigating the expression of over 5,000 genes to find an active molecule), formulation work, delivery of active to skin testing and finally clinical data is to make judgements based on almost no data. I and the company stand by the science- both the basic research that led up to the clinical study and the clinical study itself. Those that have never met me, or anyone associated with our company have made character judgements that unfortunately cause me to reconsider my openness. Statements such as " I suspect vilification will come, though, if this investigation is reviewed by a board of his peers. " serve only to lower the level of debate. As many other posters have put it here- the proof will be in the pudding. If this were a marketing ploy by us then we were sure naïve! For those of you who may have further questions regarding the Dramatic Relief lotion I urge you to contact me personally via e- mail. I have discussed the criticisms of our clinical study at length with our CTO, Dr. Fuller and have received his input on the results. I am now posting those for you here. This is the last comment I will make on our studies. If you do not wish to believe the results or that we underhandedly skewed the data or clinician in our favor, then there is nothing I can do to bridge that gap. Looks like a pretty knowledgeable person looked at the data. However, the statistics speak for themselves and that's why one does statistics on data. A paired t test looks to see if the differences in the means between 2 groups (baseline and 4 weeks) could have occurred by chance or not. The answer for the control group is that this difference is not significant, i.e. the difference in the mean severity index between baseline and 4 weeks could have occurred by chance. Thus the improvement that we see in 6 patients could have happened by chance and the only way to know for sure is to increase the number of patients. We didn't have the money to pay for this many " vehicle " subjects. For the Dramatic Relief lotion, the t test says the difference between baseline and 4 weeks in severity of the disease could not have occurred by chance and is, in fact highly significant (0.01) which is even more significant when one considers what a small n number we had (20 is a very small study). We actually skewed the study against us by using our own proprietary moisturizing lotion (containing niacinamide) that is designed to protect the skin from lost barrier function. This lotion obviously has some beneficial effect and in any blinded controlled study there is always a " placebo " effect. In our case we knew going into the study that our proprietary moisturizing formulation would help protect the skin as would the niacinamide. We could have chosen the safe route and used a non-prescription lotion off the shelves, but this would not have been a true " control " . We opted to do a rigorously controlled study and the results clearly show the anti- inflammatory properties of Quadrinone are responsible for the improved patient outlook. The question really is which lotion would these rosacea sufferers prefer to use? One that gives a patient a greater than 55% chance of showing over a 50% improvement in rosacea with the possibility of completely getting rid of the disease symptoms or one that has a 20% chance of showing a 50% improvement and no chance of completely removing the symptoms of disease? In regard to patients dropping out, there are a zillion reasons why people drop out. In this case the patients came in and signed up and then never came back. I don't know if Dr. Draelos called them or not to find out why they quit. Usually it's a family or work problem. In regard to ingredients we're very familiar with the niacinamide data. Both our " control " moisturizing lotion and our Dramatic Relief lotion contain niacinamide. We engineer formulations to enhance delivery of each ingredient we consider important, including niacinamide. Since the control lotion contains niacinamide but no Quadrinone, it is clear that this vitamin alone can't effectively treat rosacea and that if you really want to alleviate the symptoms you're going to want a product with Quadrinone, not just niacinamide. We have patients assessments and we have erythema scoring from both Dr. Draelos and the patients. There is no question that our product works at the dermal level as well as the epidermis. We have data on effects of quadrinone on cytokine and chemokine production by fibroblasts, and we even have reason to believe Quadrinone has anti-inflammatory effects on endothelial cells. One note: we only used 1% Quadrinone in this product and it is effective. We also have data that 2% is even more effective. In short there are a lot of clinical studies we'd like to do if we had more money. The data we have speaks for itself and shows that significant improvement in rosacea requires Quadrinone.
