Sure. So let me answer the question on, first of all, good to hear your voice. Thank you for asking the question. So the first part of the question is really related to VERU-111 which is our oral anti-tubulin and at the Phase 1B, which is what you're referring to is a 3 plus 3 design, where we dose escalate these oral doses in three patients at a time. And the three patients at a time will get every day seven days an oral dose of our drug followed by two weeks throughout the holiday and that's called a cycle. And then they'll go back seven days and then two weeks off, seven days and two weeks off. So every time we say that that's a cycle. And so, as you rightly pointed out 4.5 milligrams a day for seven days is the first dose and we can basically double. So we'll go 4.5 to 9, 9 to 18, 18 to -- actually not double, go by nine and then it goes to 27 and then it goes to 36. So it will go by 9. And so the question becomes where do we expect to see activity? Well, in our preclinical models it looks incredibly potent and what I mean by that it looks like somewhere around five nanomolar in concentration is where we expect to see activity. And if you look at the safety data that we did 28-day safety data, we gave the drug every day in rats and dogs where we were able to see that even in some of the lowest doses, we were able to see that we were able to achieve concentrate...ssssss ------- able to see that we were able to achieve concentrations in the blood that would be sufficient to start seeing activity with the tumor. So, with that said, we're not looking to push this thing. We believe we'll see activity before we'll see safety issue. But the first part the Phase 1b will be safety and so we will push the dose until we see a safety signal. But we expect to see efficacy before that as its open label will be able to come back. Now, the 3+3 design means that the patients, well, three patients will be treated and then after those three patients have gone through one cycle to seven days and two weeks off, we then will and we don’t see any dose limiting toxicity and we'll go into the next dose, and then next dose, and then next dose. And so, by the summer, we would expect to be completed completing the 1b and in the summer we expect the Phase 2 which would expand to 26 patients picking the dose that we learn from the 1b. And so, we're thinking that hopefully May June period maybe kind of where we'll start seeing something which will be great, it could happen sooner, we just don’t know. In terms of the safety, now what makes this spring interesting is the IV taxanes which are antitubulins and noted for having -- one is IV, because the bioavailability is such as is pretty much insoluble has to be given IV. Second thing is that because of the dose limiting toxicity of neutropenia means a drop in white cell count, can only be given once by IV every three weeks. And in our situation we're giving the drug every day for seven days and in the animal studies we are able to give the drug every day for 28 days and not see the neutropenia at this clinically relevant doses. The other side effects or which we believe what will make us unique is that we have a potential of not seeing a drop in white cell count which is a dose limiting toxicity of taxanes. And in the second thing in our preclinical models, we are able to see less neurotoxicity. So, one of the neurotoxicity side effects of taxanes is you get which call peripheral neuropathy, which means you get a numb feeling of your toes and your fingers and the animal model we just didn’t see that compared to docetaxel and another antitubuline called vinca alkaloids like vinblastine. So, those two side effects alone will make this attractive and being oral make this attractive. And so, this is a very big year for VERU-111 because we're also treating a patient population that looks like it's the largest growing segment of on medical need in prostate cancer. Because right now patients who fail androgen deprivation therapy are going to placed on abiraterone and enzalutamide. And what we've learned is if you place an abiraterone and you really squeeze testosterone down coming in with another drug like enzalutamide, this squeeze testosterone down into further, there's not much room and it's not much clinical benefit. And so, these patients are now starting to fail and when they fail they happen to go to IV taxanes. And that means that meeting the urologist to the medical oncologist and urologist would love to hold on to these patients with an oral therapy similar to what we're developing the VERU-111. So, it's exciting times for us because I think this will this next six months for sure will give us an indication of whether we're going to work in this indication that all the preclinical work that we've done in multiple animal types and multiple cell types and multiple applications suggest that we're going to you'll be fine with efficacy and hopefully safety will play out with the animal models that we've already done.
