There is no way to do as you ask, the only information is within the Lexington published financial reports.
At this present time trials are still on going and until they are completed and FDA approval is granted coupled with Wall St re IPO or third party company licensed by LEX or even buying the right to market if not a complete buy out, anything published by anyone other than the company is pure speculation.
As to a realistic present valuation, it is the value of the outstanding Stock and its present trading price.. IE;- +/- 38.000,000 X .10 = $3,800,000 but you try and buy the company for that figure !!!
Also remember that although the share price may go up when FDA approval is granted it will need to balance out and start selling to create revenue. I doubt for the first year a true value will be able to be obtained, but anyone can guess ….
Have a great day.
