[William Marshall, executive]

Thanks, Dan. Good afternoon, everyone, and thank you for joining us for our corporate update call for the second quarter 2019. We issued a few important announcements this afternoon, which will be the focus of today's call. In addition, we will be providing updates on the events impacting each of our 3 clinical stage product candidates.

First, we have regained EU and rest of world rights to MRG-110 in addition to the U.S. and Japanese rights that we had retained in our agreement as a result of Servier's portfolio realignment and decision not to pursue the development of MRG-110. Servier will continue to support the program under the terms of our agreement through February 2020. While we can appreciate the difficult strategic decisions the companies such as Servier are required to make, we believe that MRG-110 could benefit patients worldwide. We believe the safety and tolerability profile and preliminary proof of mechanism in humans generated in the Phase I studies, position MRG-110 as a Phase II ready asset for cardiovascular indications and other indications that would benefit from tissue repair and enhance blood flow.

We expect to release Phase I data at an upcoming scientific conference in the fourth quarter of 2019. While we've not announced future development plans for MRG-110, we may seek a new development collaboration for this product candidate in the future. We also announced that the team has opened over 50% of the total sites currently planned for the SOLAR trial. While we initially experienced delays in activating sites, recruitment rates at those sites are now on pace with our initial predictions. However, due to the impacts of the delays we experienced early in the onboarding process, we now expect to report primary endpoint data from the SOLAR trial during the first half of 2021. Considering the developments around MRG-110 and the SOLAR trial as well as our current cash position. We made a difficult but disciplined decision to move ahead with the restructuring of the business in order to focus our resources, primarily on the clinical development of cobomarsen, remlarsen and microRNA-29 Mimics. I'll provide more details in a moment.

Let me now turn to a more detailed review of our pipeline and recent updates. I will start with MRG-110. We are finalizing the analysis of the results from 2 Phase I trials, which were designed to deliver safety information about MRG-110 and also provide proof-of-mechanism evidence that could be used to support future clinical trials for the treatment of heart failure and other conditions where patients may benefit from increased vascular flow and accelerated healing such as complicated lacerations in high-risk patients. We expect to report Phase I clinical data on MRG-110 at an upcoming scientific conference in the fourth quarter of 2019. We can say today that based on our review of the data from these Phase I trials, MRG-110 was generally safe and well tolerated, and we believe the program is ready to advance into Phase II clinical development. MRG-110 represents the third microRNA targeted product candidate from our team has developed that has been generally safe and well tolerated and with preliminary proof-of-mechanism data in humans. We believe this differentiates miRagen's technology and demonstrates the capabilities of our team to develop microRNA targeting product candidates.

Turning to our lead program, cobomarsen. As a reminder, cobomarsen is an oligonucleotide inhibitor of microRNA-155, being developed in a type of blood cancer known as cutaneous T-cell lymphoma, or CTCL, as well as several other blood cancers where the disease process appears to correlate with an increase in microRNA-155 levels. I'm pleased to report that we've ramped up site initiation for the SOLAR Phase II clinical trial, which began dosing patients this past April.

As a reminder, we are initiating clinical sites in the United States, Europe and Australia with the goal of opening up to approximately 58 sites in 11 countries worldwide to enroll approximately 130 total patients. To date, we've opened more than 50% of the sites for this trial. As I mentioned earlier, while we have experienced delays in activating sites, recruitment rates at these sites are now approaching the pace we initially had predicted. Considering this update on the sites and patient enrollment, we now expect to report primary endpoint data from the SOLAR trial in the first half of 2021 instead of the second half of 2020, as we previously guided.

The primary endpoint for the SOLAR trial is ORR4, where the objective response rate defined as 50% or greater improvement to the severity of a patient's skin disease over the entire body with no evidence of disease progression in the blood lymph nodes or viscera, maintained for at least 4 consecutive months. Progression-free survival will be secondary endpoint. We plan to use patient-reported outcomes as additional secondary endpoints to monitor quality of life improvements. Based on discussions with the FDA, we believe that achieving the primary endpoint from the SOLAR trial could allow us to apply for accelerated approval of cobomarsen and CTCL in the United States.

We are conducting the SOLAR trial in association with the Leukemia and Lymphoma Society, partnering with the society is providing miRagen with invaluable support, which includes up to $5 million in equity funding upon completion of specified trial milestones as well as help in identifying and supporting potential patients. During the second quarter, we also announced new data from the adult T-cell leukemia/lymphoma or ATLL, cohort of our Phase I trial of cobomarsen. In an oral presentation at the 19th International Congress on HTLV. This new data showed continued durability of disease stabilization observed in patients with aggressive subtypes of ATLL.

As a reminder, this patient population historically has a very poor prognosis with few potential long-term treatment options. The data generated to date for patients treated with cobomarsen combined with a favorable tolerability profile supports our belief that cobomarsen may be a meaningful potential treatment option for patients with the aggressive forms of ATLL. We believe these clinical observations in another microRNA-155 elevated tumor type also supports the hypothesis that cobomarsen may have utility in treating other malignancies with elevated microRNA-155 levels.

Turning to remlarsen. We are currently conducting a Phase II clinical trial, assessing the safety, tolerability and activity of remlarsen in the potential prevention or reduction of keloid formation in subjects with a history of frequent keloid scars, a persistent form of hypertrophic sky. The trial has completed its enrollment, and we expect to report data before the end of this year. We are also exploring the antifibrotic effects of remlarsen in the eye. In April, we announced new data from our preclinical studies at the 2019 ARVO meeting, which support our belief that remlarsen may serve as a novel therapeutic for the prevention of corneal scarring and hazing, following ulceration due to infection or injury.

This data follows on the data announced earlier this year from our preclinical studies, investigating the antifibrotic effects of remlarsen in corneal ulceration, which suggests the top application of remlarsen may be an effective treatment to improve vision in patients suffering from multiple conditions, resulting in corneal sky. We believe these data further support that the topical application of remlarsen may be an effective treatment to inhibit corneal fibrosis and scar. We believe remlarsen has the potential to address a significant medical need as scaring of the cornea remains a leading cause of blindness worldwide with no approved pharmacological treatments.

In May, at the 2019 American Thoracic Society, we reported new data demonstrating that systemic administration of our second generation microRNA-29 Mimic, a preclinical product candidate for idiopathic pulmonary fibrosis, or IPF, efficiently reduce extracellular matrix deposition in a series of preclinical studies. We believe that these data, coupled with previous observations in human with IPF support the role of microRNA-29 in in pathologic fibrosis in the lung as well as the use of microRNA-29 replacements as potential therapeutics in pulmonary fibrosis.

This completes my review of the key programs in our development pipeline. While we are pleased with the continued progress across each of these 3 programs, some of the recent events that I just described, have impacted our time lines and prompted our decision to implement a restructuring plan that is focused on reducing costs and directing our resources to the advancement of cobomarsen and microRNA-29 Mimics, including remlarsen, while reducing investments in Discovery Research. This restructuring plan follows a review of our cost structure, which resulted in a reduction of 26 positions. These reductions are primarily in positions relating to research and corresponding project, general and administrative support and other costs related to these areas. We believe the alterations to our cost structure will allow us to continue to move forward with clinical and preclinical data generation that will inform future development decisions for our product candidate pipeline.

Before I turn the call over to Jason, I want to thank all of our employees as we work through the cost restructuring. We appreciate their diligent effort in advancing each of our clinical stage product candidates, and I look forward to reporting on a number of clinical milestones and data announcements in the second half of 2019.

With that, I will now turn the call over to Jason Leverone, our Chief Financial Officer, to review the financial results we've reported earlier today. Jason?

[Jason Leverone, executive]

Thank you, Bill, and good afternoon, everyone. Today, I'll focus my comments on the announcement we released this afternoon. First, starting with cash, we reported approximately $43.9 million in cash, cash equivalents and short-term investments at the end of the quarter, and net cash used in operations of $7.2 million for the second quarter of 2019. As Bill stated earlier, today, we announced a cost restructuring program, which we expect will reduce operating costs and extend our cash runway.

As a result, we believe that our current resources will be sufficient to fund our operations into the second quarter of 2020. The cost restructuring program announced today includes rightsizing the company and other cost reductions, allowing us to concentrate our resources primarily on the development of cobomarsen, with additional capital allocated to our microRNA-29 program, including remlarsen and other microRNA-29 Mimics. We expect the company will incur approximately $1.5 million in restructuring charges for retention, severance and other restructuring related costs, primarily during the third and fourth quarters of this year.

In terms of the MRG-110 program and our collaboration, Servier will continue to support certain development activities through February 2020. This will allow adequate time for the collaboration to complete the 2 Phase I clinical trials of MRG-110, which we expect to report data in the fourth quarter of this year. Overall, our strategy remains largely unchanged. And the team has done great work since the end of the first quarter on site initiation and the global Phase II SOLAR trial of cobomarsen and CTCL. And we expect that we will benefit from these efforts and investments in the coming quarters.

With that, I'll ask the operator to open the call for questions. Operator?

[Operator]

[Operator Instructions] Our first question comes from the line of Liana Moussatos with Wedbush Securities.

[Liana Moussatos, analyst]

For MRG-110, have you started any partnering discussions yet? Or do you have any target companies? Also what -- are you going to slow down the microRNA-29 Mimics for the eye and IPF indications? Or are you going to move forward? Then also can remlarsen leapfrog cobomarsen to the market now with the delay in the SOLAR trial? And then the fourth question is, how much decrease in operations expense will the restructuring result in versus what you've reported in Q2?

[William Marshall, executive]

Great. Thanks, Liana. I appreciate the question. So with MRG-110, as you remember, we had retained the U.S. and Japanese commercialization rights to the compound as part of our agreement with Servier. We have had ongoing business development discussions around those aspects of the asset. We have not specifically identified, but we'll continue to develop the strategy as we really complete the analysis of the Phase I beta and then pull together a package that we could bring out. In terms of the miR-29 mimics, we really -- the intent of the restructuring was to allow us to focus on cobomarsen and also focus on the miR-29 program. So we sized the company appropriately, and we're able to continue efforts. So we should not be slowing those efforts. We have a generated significant data in the ocular applications, and we will continue to pursue an update on the applications for the next-gen compounds in the setting of idiopathic pulmonary fibrosis.

In terms of remlarsen or leapfrogging, we don't believe that, that would be the case. The -- we are diligently focused on site initiation for the SOLAR trial. We believe that's the most important factor. As I mentioned, we've seen sort of accession rates at the sites that are in line with what we've seen in -- or what we had predicted. So we are really adjusting the time frame here with -- based on our ability to better model. As you know, the modeling of sort of completion dates can be a challenge, and we're zoning in on that now. And we felt it was appropriate to sort of adjust the guidance accordingly.

Jason, I'll let you comment on Liana's last question.

[Jason Leverone, executive]

Thanks, Bill. Thanks for the question, Liana. So we haven't provided an exact estimate of the cost savings that we expect from these actions. We have taken all these actions into consideration when we updated and provided a new cash runway guidance, and we'll continue to do that on a quarterly basis. In terms of our expenses, I will say that for the last -- expenses have remained relatively consistent over the last few quarters, I think, averaging around $11 million, $11.1 million back to Q2 of last year.

I do expect in the next few quarters, operating expenses to continue to increase, with some restructuring charges, that we spoke about today, expected to be incurred over the next 2 quarters as well as delivering data on the remlarsen trial and the MRG-110 trial as well before the end of the year. Also our costs that are related to the SOLAR and PRISM trials are mostly related to site initiation and patient enrollment. So I would expect those costs to increase in the few quarters going forward as well.

[Operator]

Our next question comes from the line of Jonathan Miller with Evercore ISI.

[Jonathan Miller, analyst]

I just wanted to get a little color on recent management departures? I know there has been a little bit of turnover there. I'd like to get your take on that. And secondly, I know you said that you think you have cash runway now to second quarter of 2020. That's in line with what you've previously said. So I wanted to understand that the impact of the Servier collaboration falling apart and your financial restructuring more or less balance each other out, getting you to about the same runway as you were as of last quarter.

[William Marshall, executive]

Jon, thanks for the questions. The -- in terms of the departure, we did announce that our Chief Business Officer decided to move on to another position. We appreciate all of his contributions in the past, and we really wish him all the best in his future endeavors.

The -- in regards to the questions around the sort of runway, cash necessity, I'll let Jason address it. What I will say is that as we've disclosed -- the Servier collaboration does provide for continued support for ongoing parts of the study, and we will certainly be conducting things to be able to have quality control data to be able to present. And it should have a relatively nominal effect on the changes in cash burn, but I'll let Jason comment on your question more.

[Jason Leverone, executive]

Thanks, Bill. And thanks for the question, Jon. So a lot goes into us determining our cash guidance, and we did take into consideration the impact of Servier's decision and that was correct, where Servier will continue to support activities through certain development costs through February 2020. It's safe to assume that any new trials or studies that we planned or contemplated, were -- are not going to be part of that support going forward. So to the extent that we factor that into our previous forecast, that's a change that we've worked through. We've also included the cost of severance, retention and other related costs. And then normal -- in the normal course sort of updating our development costs with our team, that puts us in this near-term runway window within a similar range we were before, all things considered.

[Jonathan Miller, analyst]

Great. For the ongoing MRG-110 trial, it seems like you do have some visibility already into safety and tolerability. Do you have anything to say about potential efficacy measures in these Phase I trials? And if the trial -- if the asset is Phase II ready, is that to imply that you think it ought to be taken forward -- the Phase I data is supportive of taking it forward into Phase II?

[William Marshall, executive]

Yes. Thanks, Jonathan. The data that we have seen, again, we're going to report this at a meeting. And we'll talk more about it in the fourth quarter of this year. Clearly, the signals that we've seen so far suggests that good safety tolerability profile as well as preliminary proof of mechanism in humans. So we've been able to identify important biomarkers that are related to tissue repair and vascularization. And we'll -- again, we want to really reveal or discuss those in greater detail at the scientific meeting in the fourth quarter.

[Jason Leverone, executive]

Can I just add something to that. We also have data from these Phase I trials that allow us to determine at least preliminary looking at dynamic endpoints dose and dose response. So I think when you look at safety, you look at preliminary proof of mechanism, an idea of what doses to use. I think that's why we're saying we believe this is a Phase II ready asset at this stage.

[Operator]

Our next question comes from the line of Madhu Kumar with R. W. Baird.

[Unknown Analyst]

This is [ Jennifer ] on for Madhu. Just a few, sort of follow-up on the Q2 '20 cash runway. Could you tell us what ongoing or future clinical study does that assume? And then in terms of the SOLAR trial, could you give us maybe a little bit more of an idea of what fraction of patients have been recruited and then sort of in parallel, how close you are to any interim futility analysis.

[William Marshall, executive]

Sure. Jason, you want to speak to the 2020 runway?

[Jason Leverone, executive]

Sure. Thanks for the question, [ Jennifer ]. In terms of the Q2 2020 runway, that assumes continued funding for the SOLAR and PRISM trials with cobomarsen and CTCL as well as completing our Phase I study and the expansion indications that's ongoing as well. And the remlarsen study in keloids, which we expect to report out later this year as well as the MRG-110 study with Servier that we expect to report out later this year.

[William Marshall, executive]

And [ Jennifer ], the -- around the SOLAR trial, we've previously stated that we're not going to really guide on accession numbers and recruitment numbers in detail. We've sort of focused in on site activation. We'll continue to update on progress. And at this point, I would say that we are -- as the data continues to mature, and we get into -- out of the summer season and into the fall season, we'll be in a better position to really be able to extrapolate towards the timing at which we would be ready to guide on the futility analysis.

[Paul Rubin, executive]

Let me just add to that. As Bill mentioned, we now have more than half the sites online and onboarded. And we now have enough data where we can model kind of the patient decision rate. That's why we're -- we did make the adjustment, but we also feel that these predictions are reasonable because we now have a good sense of the number of patients per site per month that are actually being recruited into the trial.

[Operator]

Our next question comes from the line of Leland Gershell with Oppenheimer.

[Leland Gershell, analyst]

First, couple of questions on cobomarsen. Wanted to ask, in the prior trial with the expansion indications, ATLL, it seems to have very encouraging data there. Wanted to ask when we might see the next update from the TLL subset? Would that be at ASH this year or perhaps another venue. And also want to ask about thoughts for another -- with the next expansion indication for cobo might be. And then I have a follow-up.

[William Marshall, executive]

Sure. So we are continuing -- our primary focus now in the ATLL expansion is really to focus on the durability of response in the highly aggressive patients. We're building that additional data set, it turns out that the -- it isn't -- while there is some good sort of data around Servier from diagnosis, the disease being as rare as it is, there isn't a lot of good data around kind of Servier post standard of care. So we're going to be doing some additional mining activities. We're also treating patients with some different paradigms. So in other words, not necessarily after chemotherapy reduction, but with higher tumor burden, so that we really get a good picture of the likely application of the drug. With the appropriate data set in hand, our plan would be to then move toward the communications with a plan in place with the FDA to understand the path forward. The -- we will be giving some updates -- we're scheduled at an upcoming meeting in late sort of September to give some updates, and we'll continue to update guidance on additional updates.

In terms of the expansion indications, we had previously reported at the T-cell lymphoma forum, on some preliminary observations in DLBCL, especially in the ABC subtype, and we do have the trial open to patients with ATLL, DLBCL, of the ABC subtype as well as CLL patients. And we'll continue to update as we make progress in those areas.

[Leland Gershell, analyst]

Okay. Great. And then on the miR-29 side, do you any encouraging signals we're seeing in the eye. I think you had mentioned that you have also been working on an ophthalmic formulation that would be appropriate for that. I just wanted to ask for a clinical utility where you may be in the development of that particular formulation.

[William Marshall, executive]

Right. So the -- thanks, Leland. The -- we've continued to do the preclinical work to assess various alterations to formulation that may affect sort of wettability and viscosity and things like that. We'll -- we've completed most of those studies, and we'll update on the observations at future scientific conferences. But we feel like the asset is at a point where it is near ready to move forward into evaluation necessary to move it into clinical trials.

[Jason Leverone, executive]

So the data that we reported on the formulation itself was just the drug in sailing where we've got good tissue penetration. So we don't envision there has to be much done with formulation at this stage.

[Operator]

Our next question comes from the line of Suji Jeong with Jefferies.

[Suji Jeong, analyst]

This is Suji Jeong on for Eun. Sir, could you elaborate more on the development plan for remlarsen, and given the large patient pool for cure. Do you think you're going to have to find development partner before advancing to the next stage?

[William Marshall, executive]

Suji, thanks for the question. So the remlarsen, the study that we -- the Phase II study that we're conducting now had several important goals to it. If you remember, it's an intrapatient-controlled study. So we could do a relatively small number of patients. We could control many factors around the development of keloids. I think one of the sort of confounding aspects of previous clinical trials has been the heterogeneity in keloid growth. And in our study, we've controlled the position of the biopsy that's used to induce the keloids. It's intrapatient controlled again.

And our focus is really on understanding, in this trial, what is an effect size that we see and then what would that project in terms of Phase III. And we're really using the data from this to make those important decisions that you're alluding to. In other words, is it most appropriate based on the effect size to seek out a development partner? Is it something that we could contemplate moving forward on our own? And we do believe remlarsen actually has additional applications. One of our goals in assessing it in persistent pathologic scaring was to demonstrate some proof-of-concept in pathologic fibrosis as well. So the goals of that study are multifaceted, and I think, really put us in a good position to determine the appropriate path and the appropriate investment decisions for remlarsen moving into different indications.

[Operator]

There are no further questions left in the queue. I would like to turn the call back over to Mr. Bill Marshall for any closing remarks.

[William Marshall, executive]

Great. Thank you. We want to thank everyone for taking the time this afternoon for an update on miRagen and for your support, as we work to bring life-changing medicines to patients. I hope you have a great afternoon, and thank you.

[Operator]

This concludes today's teleconference. You may now disconnect your lines at this time. Thank you for your participation, and have a wonderful day.
