Absolutely. I mean, that’s one of the big things that we’ve been looking at. I mean, by the time things actually entered the public domain, like a poster or publication, we’re -- I think, people aren’t aware of the length of time it takes to get the volume of results that are required to get to a publication. I mean, it’s not measured in days, it’s not measured weeks; it’s measured in months and years. So, we’ve been thinking about this question from a commercial aspect. And actually, we’ve had it with even some of our potential partners. The two options are, you can add the virus, because basically, all it is, you have an [indiscernible] product or a collection of blood cells in this instance, CAR-T cells that are kept at 4 degrees so that they’re viable but in stasis. They’re not replicating. They’re not doing anything. We then simply take a solution of virus and saline and apply to those CAR-T cells at 4 degrees, so that what you eventually get is adherence of the virus through its cell receptor to the outside of the CAR-T cell. And we want to do this at an MOI that engages a sufficient number of virus per cell that it will actually track well to the solid tumor. Now, the options are, we can do that at the facility, which they would create the blood product or the CAR-T product, they would terminally differentiate it by growth factors and what have you, at that point, we could actually apply the virus. And what’s nice about doing it in the factory setting, if you will, is there’s a high level of control because it’s a GXP environment. So, there will be a lot more SOPs, a lot more rigor, a lot greater ability to have testing equipment like [Technical Difficulty]. That really is dependent on stability studies, how long the virus persists on the CAR-T, and those studies are underway. The other aspect that we can do is, obviously, CAR-Ts are made in the factory. They are then returned to the hospital center for infusion into the patients. Prior to the infusion, we can have the pharmacists at the hospital make up the solution, apply it to the virus, rocket, so that there’s proper adherence over the course of an hour and then applied to the patient. So, both are available to us. Really what’s going to dictate is the stability study. The strong preference from industry partners is to sell the whole thing as a kit. So, there would be basically the generation of this fourth CAR-T that signals to the immune system. That retains both costimulatory molecules plus the chimeric T cell receptor and then, obviously, have that quality controlled to release from the clinic. That’s the preference. But it will really depend on how long that combination product is stable.
