Sure. Good question. So I'll try to address. I think in terms of pipeline, I think all the programs were exciting, right? I think that's what we pursued them to begin with. Obviously, by the way, the market potential of IBD is the largest. But I think as we looked at market conditions and general market sentiment in the microbiome, we said, probably the things we should prioritize are those that would generate not only reduction of target bacteria, right, but actually indication of clinical effect.
I think where the investor community is, they want to see an effect with the phage intervention, which is beyond the effect on target bacteria. So I think that's kind of the way we looked into it. Again, pending that the opportunity is to kind of make the cut have an interesting market potential, right? So that's why in CF and atopic derm, we hope to generate data in patients in 2022, right, versus the inflammatory bowel disease program, which we can generate data in healthy volunteers, mechanistic data.
And obviously, cancer is an earlier program. So there's just additional in vivo study. So I think that's kind of how we made the cut of what goes in into 2022. In terms of market potential, right, so atopic derm is a very large market. We're talking about a $5 billion opportunity. It's expected to almost triple in the next 5 years or so based on some of the analysts report, right? So a very large unmet need. The majority of the market is with biological, which are mostly injectable that have some safety concerns.
So there's really an appetite for something safe, especially when 1/3 of the patient population is pediatric. So something that would potentially be topical and safe can take a large chunk of that market. So that's quite an exciting opportunity, and we see that with -- incoming from potential partners, and I think the partnership we've announced with Maruho, right?
In the field of cystic fibrosis, you do have the leading antibiotic that CF patients are using, selling north of $600 million per year, right? So that's quite an opportunity. And if you can have something that could potentially be better, this could even be a larger update, right? The whole -- I think if we look at what's happening in CF, we've seen Vertex building a very large franchise [indiscernible] right, taking $6 billion annually.
Of course, I don't think this is going to be of that extent. But it should be -- if it has the profile that we want, somewhere between the tobramycin and ongoing it towards the market sales that Vertex has generated.
