Good afternoon, and welcome to today’s earnings call of Omeros Corporation. At this time, all participants are in a listen-only mode. After the company’s remarks, we will conduct a question-and-answer session. Please be advised that this call is being recorded at the company’s request and a replay will be available on the company’s website for one week from today. I’ll turn the call over to Jennifer Williams, Investor Relations for Omeros.

Good afternoon and thank you for joining the call today. I’d like to remind you that some of the statements that will be made on the call today will be forward-looking. These statements are based on management’s beliefs and expectations as of today only and are subject to change. All forward-looking statements involve risks and uncertainties that could cause the company’s actual results to differ materially. Please refer to the special note regarding forward-looking statements and the risk factor section in the company’s quarterly report on Form 10-Q, which was filed today with the SEC, and the risk factors section of the company’s 2020 annual report on Form 10-K for a discussion of these risks and uncertainties. Now, I would like to turn the call over to Dr. Greg Demopulos, Omeros’ Chairman and CEO.

Thank you, Jennifer, and good afternoon everyone. We appreciate you joining us for today’s call. We will start with the corporate update and then provide an overview of our third quarter financial results. With me today are Mike Jacobsen, Nadia Dac, Cathy Melfi and Steve Whitaker; our respective heads of Finance, Commercial, Regulatory and Clinical. We’ll begin today with narsoplimab, our fully human monoclonal antibody targeting MASP-2. MASP-2 is the effector enzyme of the lectin pathway of complement. On October 18, we announced receipt from FDA of a complete response letter or CRL regarding our biologics license application or BLA, for the treatment of hematopoietic stem cell transplant associated thrombotic microangiopathy or TA-TMA. We will have a Type A meeting with FDA to help determine the most expeditious route to approval. Our briefing package for the Type A meeting with FDA is nearly complete and once we have received all externally generated components, we will submit the package together with a meeting request to FDA. Because this is a Type A meeting, the meeting request can only be submitted in conjunction with the completed briefing package, and no changes can then be made to those materials. The briefing package will address FDA’s concerns noted in the CRL and will include a detailed history of communications with FDA, which has been reviewed and confirmed by outside regulatory legal counsel. Once the briefing package is assembled and submitted with the meeting request FDA regulation requires that the Type A meeting be scheduled within 30 days. FDA has indicated that they are ready to work with us to identify the most expeditious and least onerous path to approval for narsoplimab in TA-TMA. In our conference call on October 18, we discussed that in the CRL, FDA expressed difficulty interpreting narsoplimab treatment effect, given…

Thank you, Greg. Our OMIDRIA business continues to see solid growth in the third quarter with revenue growing at 4.1% driven once again by the Ambulatory Surgical Center segment. The ASC segment has fully recovered following the decision last December by CMS to restore separate reimbursement for OMIDRIA in the ASCs. In fact, in the third quarter, this important and largest segment of our business surpassed Q3, 2020 ASC sales performance just prior to losing reimbursement by 7%. Our efforts with establishing partnerships with ASC chains and groups of ASC is owned and operated by private equity groups continues to drive momentum. This growing segment now represents nearly 20% of our overall business. The fourth quarter is already off to a strong start. As I shared on the last call we’ve been working on a brand new OMIDRIA promotional campaign that is launching this week at the Annual American Academy of Ophthalmology conference in New Orleans. Our sales force already has the new promotional material in their hands featuring a surgeon performing his successful cataract procedure on the stage of an OMIDRIA vial cap. They will be using the new material in our booth at the AAO conference during which we’ll be engaging the healthcare practitioners through one to one discussions. This compelling campaign was tested in both qualitative and quantitative research among 124 ophthalmic surgeons, some of whom were not familiar with OMIDRIA. It consistently stood out as being memorable, unique and clearly demonstrating that OMIDRIA helps pave the way for surgical success without detracting from the surgeons’ crucial role in the process. The focus of the new messaging will be on what surgeons in our research cited as most important to their procedure decisions, specifically OMIDRIA’s effect on the reduction of both intra-operative and post-operative cataract surgery complications, including a reduction in intra-operative floppy Iris syndrome, post operative cystoid macular edema, breakthrough iritis, post operative pain and reduction in the use of people expanding devices, all of which have been demonstrated in published studies. The campaign is also debuting online this month as we create a greater digital presence for our brand along with optimized search engine tools. Turning to Narsoplimab. Our field team is continuing its focus on account profiling in top transplant institutions, creating center specific plans to ensure rapid access to Narsoplimab post approval. In addition, we launched our disease education speaker program last month. Next month as planned, our team will have a significant presence at the American Society of Hematology. With that I’ll turn the call back over to Greg.

Thank you, Nadia. I understand that our listeners have been hearing some background noise during this presentation. I will just let you know that it is raining quite a bit in Seattle and that’s the sound of the rain hitting the windows here in a conference room. Again, rain in Seattle being an unusual phenomenon, but one that we’re dealing with today. So with that, let’s now turn to the rest of our pipeline. Our MASP-3 program is advancing in the clinic. MASP-3 is the key activator of the alternative pathway of complement. And Omeros continues to expand our broad intellectual property position around both MASP-3 and OMS906 our lead antibody targeting MASP-3. Recent data from our OMS906 phase 1 clinical trials show high level suppression of alternative pathway activity. Based on our phase 1 data we’re quite comfortable with our targeted OMS906 dosing of once monthly subcutaneous and where intravenous dosing may be preferable, every other month IV dosing. We’ve decided to forego the multiple ascending dose portion of our phase 1 work and healthy subjects in favor of moving directly into patients with paroxysmal nocturnal hematuria or PNH, who have an unsatisfactory response to the C5 inhibitor Narsoplimab. This shift should meaningfully accelerate the development timeline for our 906 program in PNH. Our MASP-2 lifecycle management programs beyond Narsoplimab are also advancing well. OMS1029 or second generation and long acting math to antibody is on schedule to enter the clinic next summer. We expect that OMS1029 will be dosed subcutaneously at a frequency no greater than once monthly. Similar to that for OMS906 or clinical plan for OMS1029 is to combine our phase 1 and phase 2a clinical trials here also significantly shortening our development timeline. In addition to OMS1029 for subcutaneous delivery, our small molecule MASP-2 inhibitors…

Thank you, Greg, as we noted earlier, OMIDRIA in total revenues for the third quarter, one where sales are historically slower than other quarters were $30 million, an increase of 1.2 million or 4.1% over the second quarter. Our net loss for the quarter was $22.7 million or $0.36 per share. This includes non cash expenses of $6.4 million or $0.10 cents per share. As of September 30, we had $50.4 million of cash, cash equivalents and short term investments available for general operations. We also have a $50 million accounts receivable base line of credit, which allows us to borrow up to 85% of our available accounts receivable borrowing base after certain reserves. As you may recall, we also have an aftermarket sales agreement allows us to sell from time to time, up to $150 million of our common stock. As usual partnering opportunities are also present. During the third quarter, and especially in September, as we come out of the slower summer months, we have seen a steady increase in the midrise sales to AFCs. Growth has continued into the fourth quarter as weekly units sold to ASCs have repeatedly set all time highs. Hospital sales have remained consistent with the second quarter and are actually higher than expected. This is particularly satisfying as we do not currently have separate Medicare payment in the hospital setting. As Greg mentioned, we are pursuing a variety of options including the No Pain Act to regain Medicare reimbursement in the hospital setting. Costs and expenses for the third quarter were $48.3 million, a decrease of $4.6 million from the second quarter of this year. The decrease was primarily the result of reduced research and development costs due to the timing of certain preclinical research activities. As Greg mentioned, during our October conference call, we have been gating our Narsoplimab sales and marketing expenses until we receive a definitive answer on FDA approval. As I stated previously, we are expensing our supplement manufacturing costs and time until the timing of approval in the U.S. a certain. Interest expense for the third quarter was $4.9 million and consistent with the previous quarter. Last week, CMS issued its final OPPS rule for 2022 which reconfirmed separate payment from OMIDRIA in the ASC setting. With the reimbursement concern currently off the table for ASC customers, we expect OMIDRIA revenues will continue to increase as ASC customers ramp up their use of OMIDRIA and our customer base continues to grow. We expect overall research and development costs will remain effectively unchanged in the fourth quarter of 2021 compared to third quarter of 2021. We also expect that our selling general and administrative expenses during the fourth quarter of 2021 will be similar to those in the previous quarter. Interest expense for the fourth quarter should be consistent with the third quarter at $4.9 million. With that, I’ll turn the call back over to Greg. Greg?

Thanks Mike. Operator, you can open the call please to questions.

[Operator Instructions] Your first question comes from the line of Colin Bristow with UBS Securities.

Good afternoon and thanks for taking the question. I appreciate you to sort of comment on the CRL. But just bigger picture on the path forward if FDA were to require a new controlled trial, is this something that you would be willing to fund or would you ultimately see a better ROI on the capital and other programs? And then just on the IGAN phase 3, could you give us an update on enrollment and subsequent timing of the readout there? Thanks.

Sure, an answer to your first question, Colin, I don’t think we expect that that’s going to be the result. So, I’ll hold on that question and that again, I don’t think that’s something that certainly that we’re expecting. I think with respect to the IGAN phase 3 readout, I think we’ve been targeting end of 2022. That is going to depend on resources with respect to these other programs, specifically, obviously the BLA, which is our primary focus. Could that slip into the following year? I would think possibly. If it did, I don’t think it’s going to move much into it.

Your next question comes from the line of Greg Harrison with Bank of America.

Good afternoon. Thanks for taking our question. On the OMS906 program, how fast can this move given that you’re expediting the clinical program and when could we see potentially de-risking data in PNH and then where do you see PNH within the context of diseases that could potentially benefit from MASP-3 inhibition?

I think our current plan is to initiate the PNH program and early in 22. And again, this would be a phase 1b program. So I think that we can move relatively quickly through that. I think with respect, Greg, to your question around where do we see PNH fitting within the overall, sort of the overall pantheon of indications for 906? I think it is an initial foray to demonstrate the effect of 906 and potentially the benefits. The advantage is probably a better word of 906 over other alternative pathway inhibitors with respect to dosing and we’ll look and see what other advantages are there. We see the breadth of indications for OMS906 as quite large. There are indications that are focused obviously on ultra orphan or orphan indications that have life threatening implications. There are other broader indications that don’t have that same life threatening component, but certainly have life altering components to them. And those are also areas of focus. So we see it as the initial foray and the objective would be to move from there more broadly.

Your next question comes from the line of Steve Brozak with WBB.

Yes. Hi, Greg. Thanks for taking the questions. Greg I know that you can’t speak about what’s taking place with FDA, but you had significant support from the clinicians, the clinical community and the KOLs. What are they doing right now? What are they expressing to you and can you just remind us of what, how this plays into the standard course of therapy right now for the patients, that Narsoplimab would be appropriate for place. Thank you.

Sure. Thanks Steve. Like I think that the response from the thought leaders was one of surprise, I think, clearly one of disappointment. They remain strongly supportive of the drug and what I think we all see as the benefits of the drug for patients with TA-TMA. I think that is underscored by the number of requests we continue to receive for compassionate use, not just for adults, but for children. And some of those being for really very young children on the order of several months or a year old who have failed other therapies and those therapies include eculizumab. And then the request for use of Narsoplimab comes and we provide it. So, I think the support remains strong. We continue to work with the thought leaders in this field. And I think we are all hopeful that we can get Narsoplimab over the finish line as quickly as possible. There is no approved treatment for these patients and certainly in the adult population. There really is, it appears no good even off label alternative. So there’s an obvious urgency here. And I think we’re all feeling it. I think the thought leaders are sharing that feeling. And I think collectively with FDA, we need to figure out how to get there as quickly as possible. Let me stop and see if Steve Whitaker our head of clinical has any other comments?

Well, Greg, I think I just echo what you said. The thought leaders are disappointed who spoken with not just thought leaders but other physicians who have used the drug investigators and trials or people who’ve used it under compassionate use. And as you said, compassionate use request continue to come that has not abated at all.

Your next question comes from the line of Ram Selvaraju with H.C. Wainwright.

Hello, can you hear me?

Hi I can Ram, how are you?

Very good. Thanks very much for taking our questions. Firstly, I was wondering if you could clarify kind of some of the potential scenarios for the path forward with Narsoplimab and TA-TMA. So, if your upcoming interactions with the agency proved favorable is there a situation in which this might not be treated like a class two resubmission or should we be looking at that as kind of the default pathway?

Good question, like our hope is that when we meet with FDA, and have discussions and present our analyses and other information that this could well result in a class one race submission? Can we promise that? Absolutely not. But that’s certainly the objective. And I think that is our focus. So you’ve kind of put your finger directly on it. That is our focus. And again, we believe in the strength of the data, we believe in the interpretability of the data. And I think that the thought leaders concur. So somehow we need to navigate this and get the drug approved as quickly as we can. So that it is available for physicians and for their patients. I mean, I know that that sounds like a very trite thing to say and a commonly used phrase, but I mean, in this case, it’s really true. It’s true, which is why we continue to get the request for compassionate use. So I think that underscores that. So I don’t know if that answered your question Ram but if not, let me know.

No, that’s helpful. Secondly, this is kind of a three part question. I apologize. But the three parts are as follows. Firstly, if we look at specifically, Narsoplimab in the context of nephrology, what other primary proteinuric kidney diseases you anticipate are likely to be promising avenues for future development given what you’re currently seeing in for example, the IGAN context? Secondly, with the development of 906 can you give us a sense of what the likely size of the total target patient population might be in the context of you know, for example, positioning this drug post ravulizumab use. In particular do you think that there is any potential for applicability or development of 906 in Neuromyelitis optica spectrum disorder? And lastly, can you just give us a little bit more information on how both Narsoplimab and 906 are going to be positioned relative to 1029, the long acting agent that you mentioned earlier because I just wanted to try to get a sense of strategically how you’re planning to position these pieces on the chessboard. Thanks.

Sure. I’ll just note that was four questions not three Ram. But your first question on the extent of nephrology indications, those are broad. And the data coming out, not just from us, but from multiple independent research groups show that the lectin pathway is not just involved in IgA nephropathy. So not just involved at the glomerular level, but also at the tubular interstitial level. What’s the implication of that? Well, the implication of that is quite large. If all of that is correct and it certainly appears that it is correct what that means is that the application here is really and this is going to sound broad, but really any renal disease where proteinuria is a component. So when you think about end stage renal disease or renal diseases that advanced to end stage renal disease, the common pathway there is tubular interstitial disease. And if Narsoplimab is affecting that which it there’s evidence that it is that moves from glomerular diseases like IgA nephropathy to broader indications. So specifically things like lupus nephritis and others. So if you think about renal disease in general that’s a possibility. Your second question about 906 and the patient population versus treatment post. I think you were asking not about the patient population, but the size of the market post treatment with ravulizumab remember that C5 inhibitors and PNH create, they treat the intravascular hemolysis. But they create extra vascular hemolysis through C3B deposition on the surfaces of those red cells or erythrocytes, which are then cleared by the reticular endothelial system. What we see, and again, we haven’t been in PNH patients. So all of this as ex vivo, or in vitro work that we’ve done what we have seen is that inhibition of MASP-3 blocks both the intravascular…

Yes, you did. Thank you. This has been very, very helpful. I’ll jump back in the queue. Thank you.

Our last question comes from line of Eric Joseph with JP Morgan.

Good evening. Thanks for taking the question. Just a few from us. The first on the top of TA-TMA. Just wondering if you could speak to which division of FDA consulted with and developing an advising endpoint selection summary of the TA-TMA study is the same division that ultimately reviewed the DLA package to kind of get a sense of whether review might have been impacted by the reorganization of past couple years. And then on 906, can you just know, whether you from the healthy volunteer phase 1 have a sense of targeting engagement and alternative pathways, especially in some ex vivo studies. And how that form starting ghost election in the PNH phase 1b?

With respect to your first question, the division and again, it was a little muffled Eric, but I think I got it. The division with which we’re working in TA-TMA is the non malignant hematology division, which is part of OCHEN, the office of cardiology, hematology or non malignant hematology, endocrinology and nephrology. Now, it is the same division but as you’re pointing out, during the reorganization of FDA, this specific division moved out from under the office of oncology, which is Rick Pastor’s group and then moved into OCHEN, the director of that office was Ellis Unger. So there were some changes in that transition and the reviewers on our BLA, and then in August, Ellis Unger retired from FDA, and currently the office does not have a head. They have a deputy director. So there have been some changes between our sort of pre-BLA period to our post-BLA period. With respect to 906 and target engagement, 906 is highly specific with or for MASP-3. The PK/PD data that we are generating in the phase 1 study, I think show pretty clearly that we are able to suppress alternative pathway activity and again these are the data that we have in healthy subjects. So we look to see the same data in patients. But the expectation is that should be the case. With respect to our dose selection that is, that’s based on our, again preclinical work that we have done the animal work that we have done that’s been refined by the data coming out of the phase 1 trial. So I think that answers your question. I think, again, as I said, we’re quite comfortable that our dosing around 906 will give us more than adequate suppression of the alternative pathway. And both the once monthly subcutaneous routine and where it might be more advantageous or preferable in specific indications for IV dosing our expectation is that that would be frankly, every other month.

That’s helpful and just a follow up on OMIDRIA if that’s all right.

Yes sure.

So a couple quick ones here. First housekeeping item, whether you could talk about any, whether there were any shifts in inventory builds quarter-on-quarter worth noting, and then with the formalization of this separate ACS payment, or at least the expectation there. Is there any -- just trying to understand that the growth drivers near term that you’re seeing, are there any low hanging fruit.

Sorry I missed the term. Can you say that again? Are there any?

Are there any low hanging fruit in terms of new ASC accounts that you might be looking to carry the products with formalization of the separate payment schedule?

Sure. In response to your first question, regarding shifts in inventory build, the answer is no. With respect to no pain and in advance of that having ASC accounts coming on board, we’re seeing substantial increase in the number of accounts as well. This has been the result of our focusing not just on individual ASCs, but on chains of ASC. So whether those are private equity group held ASCs or other collections of ASCs that has helped significantly. In addition, I think we’re seeing as a result of the reimbursement from CMS, we’re seeing real increases and met advantage and commercial payers, paying now reimbursing appropriately for OMIDRIA which has been really great to see because that’s also a key, obviously, to continuing to grow the business. But let me see, I’m going to turn this over to Nadia and see if Nadia if you have anything you’d like to add to that.

Yes, I agree with everything that Greg said. And I will also add to the fact that one of our key strategies is to drive depth and breadth of the ASC. So yes, we’re not done with the ASCs that are coming on board. We’re really pleased with how this business has not only recovered but actually is doing better than before we lost reimbursement. So our focus on executing against that strategy coupled with the market access strategy that we’re executing against to make sure that we get these wins and pull them through at the ASC level are really the two ingredients that’s helping us drive that growth. It’s a bit of a grassroots from the bottom up and top down approach that we’re doing.

Just an add up. Just with all the color there, I wonder any plan to implement guidance for OMIDRIA going forward?

Again missed a good part of that question. Can you repeat it?

Any plans implement guidance for OMIDRIA subsequent updates?

Yes. Not currently. But I think again, we’ve talked about the growth that we have seen in the fourth quarter already. We also mentioned I think that we have reached, repeated all time highs in the ASCs in the first part of this fourth quarter. And that’s not just since the re-initiation of separate payment, but that is since launch, that we are seeing these repeated all time highs. So I think we’re quite proud of what the group has been doing. We’re seeing the hospitals are holding their contributions as well to the overall success of the program, despite the fact that we’re not even reimbursed in the hospital outpatient department. So we see opportunity for really significant growth across the ASC and HOPD settings for OMIDRIA.

I’d now like to turn the call back over to Dr. Greg Demopulos for any closing remarks.

Thank you, operator and thanks again, everyone for joining us today. Understandably the near term focus is on bringing Narsoplimab over the line to FDA approval in TA-TMA. It’s important to remember though, and I think we’ve hit it that we have additional indications advancing in phase 3 trials for Narsoplimab as well as our other exciting programs our MASP-3, 906, our next generation MASP-2 inhibitor 1029 and our adoptive cell therapy program either progressing through or slated to soon enter the clinic. We also have the benefit as we’ve just been discussing of what’s shaping up to be a $120 million plus net revenue generator in OMIDRIA. So we’re comfortable with the way that things for Omeros are coming together. As always, all of us at Omeros appreciate your continued support, and have a good evening.

Ladies and gentlemen, this concludes today’s conference call. We thank you for your participation. You may now disconnect.
