Thanks, Seth, and thanks for everybody dialing in. Warm welcome from my side. And I will be referring to slide numbers that you also find on our home page. So please go there. Perhaps, then it will be much easier to follow my speech. So the first year -- first half of this year was really transforming for us at Molecular Partners. And I'm not talking about the global biotech crisis and the conjunction with need for the full Phase 3 for Ensovibep that had that negative share price reaction that we're all aware of. No. I'm talking about the moment when we unblinded our first-ever Phase 2 blinded trial at Molecular Partner. That was in early this year, and it was really an amazing moment for all of us. It was the first time we did so unblinding and seeing that the data hits that we have safe patient lives, our job did exactly what we have designed it for. And that we have done in record speed in 18 months from idea to those data with a trispecific anti-COVID product. We're also sad that it then didn't go through, and the EUA still open now come to that, but we definitely have wished for another outcome. But the work by the team, the engagement, the energy that we bring and the validation that is still there. And together with the strong cash position, that is really what puts us in an optimal position to execute our strategy and build value going forward. Now on Slide 2, that's our disclaimer. I'll echo what Seth said, I will be making forward-looking statements. Now Slide number 3. I'll start with the science highlights, and I will start with 533, which is our AML drug. It's trispecific, bispecific making great progress to the clinic sites are approaching us to be part of that clinical trial. There is a huge excitement. We have presentations upcoming, and I will also have a slide as a, call it, pertain razor safe to date for an ASH meeting, where we invite you all to join and listen to the experts talk about 533. 317 in Phase 1. We're excited about that. Why are we excited? We're reaching 1 milligram per kilogram. That's the dose where others started to see or already before, had those limiting toxicities. So far, we're going strong on that, and we're very hopeful to be able to dose escalate and have meaningful data in the second half of this year but also next year. We have in Ensovibep, I just spoke about that, the positive data, the license to Novartis or the option exercise, 150 million milestones, 210 million in total. I think that puts us in a great position as you will see. But also, the EUA is still open and pending and should the variant of concern come back that is stronger, I think that EUA will also be used. At the same time, Novartis is still engaged with the FDA, but to find a design that in the current situation allows Phase 3 is not trivial, and they're working hard on that. We have Radioligand Therapies and on the right side of the slide. This is something that we're not only moving forward with Novartis, but also internally, and I will highlight that in a few slides down the road. Just give you a bit more reason why we think DARPins are meaningful. And we have Abicipar back on this slide as the team has solved likely the inflammation problem and how we want to remove the inflammation causing agent and see the path forward with the FDA. We will not fund this trial, we will not run that trial, but we will definitely see if we find somebody who will do that. And maybe the most important point here, and this refers back to the global situation. I mean, it's not every -- that every biotech can say they're funded into '26. We have 285 million in cash. We have a great team. We have a strong pipeline building. And we are in the best position you can wish for to execute and go forward, while many others actually have to make sure that they actually survive, we can really build value and thrive. Let me just use Slide number 4 for a recap of our strategy, and it also explains a bit and helps you understanding which programs do we invest as molecular partners and which ones maybe are more for partnering. The first one is, true patient value in an early clinical readout by directly changing the course of disease. So what we're looking for is sort of single agent activity. And that's something like Ensovibep, like AML, and it's a bit less like 317 or 310, where your Phase 1 is a safety trial, then you go signal seeking in combination. We can't afford that, and that's kind of out of strategy going forward. Everything that will come that we will introduce also Radioligand, you can be sure that we can see value in an early trial. Second point, DARPins provides a unique solution. And I think that's the one point that really sets the platform part that we're not going to try to do to me-toos or even me-betters, but really solutions that matter that are as unique to DARPins as they can be. And the biological hypothesis. So we like clinical problems that have a clear biology, a problem that showed itself clinically that we can solve and that we also can test preclinically if we're on the right track. And as our name says, as you will know, partnering, partnerships, Molecular Partners, that's really in our DNA. And we always use collaboration. We had several just on ensovibep but also -- and I'm talking about academic collaborations, clinicians, also pharma and biotech collaborations to advance what we're doing and always tailored to each individual program. And moving now to Slide number 5. This is a pipeline overview, and you see the whole pipeline from Ensovibep Radioligand therapy the lower two boxes, that's where we're really investing in new ideas. So in fact, there you see mostly oncology but also some additional infections to these work and where I will spend time in 317, 533 and the Abicipar and Radioligand Therapy. Abicipar will be the last one I will cover. Let's start with 317, the clinical candidate that is now in Phase 1. What are we trying to achieve? Immuno-oncology is great but too few patients actually can profit. And that's where -- the problem is that the immune system, the immune activity in the tumor is not strong enough. And CD40 is a target that activate immune cells. It sort of heats up a tumor that a, call it cold tumor could become a hot tumor. The problem with CD40 is if you heat up the whole body, you have side effects and your dose-limiting side effects at rather low doses. What we're trying to do is we're taking a DARPin binding to FAP and CD40. FAP is tumor local multimer and if FAP binds in CD40 at the same time, that causes the CD40 on immune cells to cluster and activate. We get intra-tumoral immune activation without systemic toxicity. That's the aim. We have shown that preclinically, we have shown with 310 that the FAP module actually goes to the tumor and can cluster 4-1BB in that case. And now we have reached a dose level without DLTs, where others actually had to stop before they reach that, that's the 1 milligram per kilogram dose. So we're excited about that, and we are filling those escalations, and we're hopeful to also reach the next doses going forward, and I have a slide on that. While the safety is obviously key, and that may be the unlocking event. We're also looking into PD markers. So can we see those cells activated than we did through parabiopsy and as I was speaking about strategy, we will likely partner this asset as we cannot then go into combination trials, that's something then for next year? Just a reminder on Slide 7, we're also giving a bit more clarity on doses. We started with a very low dose, 0.03 milligram. We ramped up now to the 1 milligram per kilogram cohort. That's where we are. We will try two things here, go to a higher dose and also more frequent dosing, obviously, always looking at safety and the PD. What is -- why do we do both every 3 and every week, that's also the partnering dimension as in combination trials, you want to have the flexibility to go more often is the partner product is given more often and to Q3 weeks would allow you a more extended less frequent dosing, but then you can actually choose what you want to do. And I think partners will very much respect this extra activity. Let's go to the -- yes. And so kind of we're recruiting, and we will update as we go. So let's go to the next program, which is 533. This is an admitted key driven selective killing instrument for blast and leukemic stem cells. What's the problem? The problem is AML remains a deadly disease. Leukemic stem cells are the driver while blast or columns killer. We need to kill both, but we have to do a focus on the leukemic stem cell. They are really difficult because they're very less sensitive to chemo. They are -- they don't have good strong surface markers. And what we have now tried to do is the following. LSC. So, Leukemic stem cells and blast, they do express CD33, CD70, and CD123. CD70 is rather specific. So there, we take a high affinity DARPin 33 and 123 are also in healthy cell. So we go for lower affinity. That's what we call optimized affinity. So we tried to kill those cells that have either 70 and 33 and 123 and not the mono 33 and 123. And that would then open a therapeutic window that we can use MP0533 in AML set for targets that usually have a very narrow or even closed window and others have tried in sales. Preclinical results show that, that works we also could show the preferential timing of leukemic stem cells and blast in ex vivo patient samples, and that's the strongest data you can get. That's what we say is high translatable value as we take samples from these patients and could show the differentiator leukemic. First, in human, we're very excited for that. So we're progressing towards that moment, and we will give you an update at ASH. I have a slide on that. How will the trial look? This is a bit more information. It's AML and high-risk MDF patients. Inclusion criteria are listed here, also exclusion criteria, which is not to be underestimated and you see we'll try to include around 20 to 45 patients. Primary endpoint is safety and tolerability, but main secondary endpoints are also efficacy. We do believe that this molecule will show itself in the Phase 1, and we will know if we have a drug candidate in hand or not. Very different to 310 or 317 that needed to have much longer clinical trials until they did show value. Again, trial initiation plans for late 2022. And as I have pointed out before, Slide number 10, the ASH event. So that's really the holy curtain raiser for the program we want to bring together key experts and also with you discuss how they see the program and where the value of it will be. A few words now to Slide 11 on Radioligand Therapy. So we all know radiation is a very good way to kill tumors. We also know it is very limited scope to tumors that are well localized. And I think they can do up to 5 lesions. But then it's done. The delivery of radiation with small or large therapeutic modalities like antibodies or peptides, can work but is restricted. We believe the DARPin could really bring a more general solution. It is small and ultra-high affinity and it can bring the radiometric for high accumulation in the tumor, very fast half-life, so limited systemic exposure, good penetration through the size and high affinity will keep it at the tumor longer. What we're now working on is really the kidney exposure, so limiting the kidney exposure. That's work ongoing. We have demonstrated the penetration at the affinity part. We have validated indirectly with the collaboration with Novartis and kind of ongoing is optimization for kidney exposure. And then when we're there and we are kind of moving forward, we will also work on first candidates and announce those ideally, I hope I can see standing here and do that next year. Just two slides on the science as we are excited about that. So I was before pointing out the antibodies and the peptides. So low molecular weight compounds are usually peptides or peptide derivatives. Antibodies are good, but they are large. So they have less tumor penetration, and they also have a higher exposure to normal tissue as they do circulate very long. And unfortunately, as antibody fragments up to single changes at least don't bring the deep tumor penetration. They're too large. You have to go below 20 kilodalton, and that's where DARPins are. Now peptide, low molecular weight compounds, they are -- have many benefits but usually, they don't have the super high affinity and they're also restricted to some targets. So that's kind of exactly the sweet spot where we think we can actually have all the benefits of the antibody combined with the benefit of the small size. I'm just going to Slide 13 that you understand how such a flow would look like. We have ritual with the tumor. We infuse the drug. These are not one for one, not half last extended, so no HSA DARPin. The drug, it's a lot for the whole body goes everywhere also into the tumor and deep into the tumor. We stopped the infusion. The drug excreted very fast through the kidney. This is first kidney pass so literally within an hour or so the body has no DARPin or radio activity. And we actually, with the high affinity, we stay in the tumor for a long time and the radiation can do its job. We're very excited about this. Obviously, we can do that alone. So we're also speaking with companies that have radioligands and that also work that is ongoing by our collaboration and alliance team. With this, I will kind of stop here, and I'm happy to hand over to Andreas to give you a bit more flavor on the financials where we stand. Andreas, floor is yours.
