There's three things I'd say in relation to this.It's not just OTIVIDEX. OTIPRIO has been a disappointment for them too. It passed its Phase 3 study and made it to market, but it only generates around $600k in revenue for them a year. According to their financial guidance, they have enough money to fund the company for 2 years. That's not really enough time to get OTO-313 and OTO-413 out the door. The only way that would work is if they completed a successful Phase 2 study for one of those drugs (probably OTO-313) and then raised more capital. I suppose this path would be a possibility, but it would put some serious strain on the company.
1. OTIPRIO is still a fairly new medicine and as a result I think it will take time to get a bigger market and bigger demand. For example you cannot get it in countries like Australia yet. As a result if availability is limited to just US at present then this is really going to limit the amount of money it generates.
2. The funding issue might seem concerning in the short term, however I think that it is still too premature to assume that this therefore means a questionable outlook for Otonomy. One thing that I think we will see is further funding from other sources such as shareholders as you have stated if they have success with other medicines or clinical trials.
The other thing worth noting is that they have reached the agreement with the Japanese company Kyorin to do the OTO-6XX clinical trials. There seems to be a real likelihood that Kyorin would know Otonomy could get the clinical trials done for OTO-6XX as it is almost unfathomable to think that Kyorin would sign an agreement with another company who couldn't get this done. They seem to also have the cash available to do the Phase 2 clinical trials for both OTO-413 and OTO-313.
3. I reckon that part of the reason Otonomy has stated that they only have 2 years of cash available is for accurate stock and financial reporting.
