Soriya, you are right about the "preclinical compay". But Rgls is one of very rare companies in miroRnai that in my knowledge is the frontier of new drug company. I started getting in at 7 and now adding up for every other time it dropped. For me the future though is still unpredictable, but if it makes it, can be very bright and beyond. Investing in this company needs patience of at least 3-5 years.
Best lucks !
