Adding to the link that pinkynose has provided, there is some background to ARA 290 here Discovery of a Master Regulator of Injury and Healing: Tipping the Outcome from Damage toward Repair .

Although the article is written by an employee of Araim the science looks good to me - most of the cited references are from investigators with no association with Araim.

My take on it is that ARA 290 is in the "This is a very good idea." basket though whether it survives clinical testing remains to be seen.
