Sure. So I'll jump in. So I think if you look into the different programs, right, I think it's different in terms of validation for every program, right? In acne, we know topical antibiotics are used. We know C. acne is kind of the major component, that's what most therapies are going after. But there's now more and more issues basically with topical antibiotics. And here, we're building a basic -- a better mousetrap, right? We're trying to overcome resistance. We're trying to overcome biofilms and provide a safe and effective treatment.
If you look -- if I look at time lines, right, CF, we know these patients take antibiotics. We know that when the bacteria is sensitive, they do better briefing parameters or work, improve in CF patients. But just due to the prolonged usage of antibiotics, right, they become more and more antibiotic-resistant, biofilm is formed and you stopped responding to therapy. So here again, phage can overcome antibiotic resistance, can have anti-biofilm capability.
And moreover, I think in CF, there's even evidence of compassionate use, cases of patients that we treat with phage successfully, not only reducing the target bacteria as well as improving lung capacity. And in atopic derm, there has been historical evidence that antibodies did have effect in reducing Staph aureus and improving parameters. There's now even new studies, right, the likes of [ 4k ] and we're coming out of UCSD that shows that reducing this bacteria is having an effect.
And again, in atopic derm, you just cannot use antibiotic chronically, right? This bacteria is so antibiotic-resistant, that's just not an option. Same thing in IBD, right? These patients cannot be chronically treated with antibiotic. It messes up the whole microbiome, messes up with their immune system. So there's a clear need for a very precise approach. And in IBD, I think it's all based on the excellent work that was published by Professor .
