To my understanding, IPIX needs completed Phase 3 Positive tests to demonstrate that they have 'Save and effective drugs'. Until then then, IPIX has formulations that may show promise.
Plus, IPIX is rapidly running out of funds to continue further testing on their own, hence the desperate .25 funding from Aspire for 8M shares to only get $2M in cash.
20 CDA's only show that there are companies that want to have a look at what IPIX really has proven to date, not that they will be involved in some 'Bidding War' with other BP's.
Share Price also indicates that there is no insider buying, as the chart indicates SP is trending into the .30's.
All combined, it's not looking good currently for IPIX. Leo's silence on key issues of concern, indicates (to me), that there are more problems with the company than we know.
