Neal?.

Thank you, Kamil. Hello, everyone, and thanks for joining us today.

I will start with an update of our clinical development programs and other business highlights, then I will hand it off to Brett Fair, our Head of Commercial, who’ll then briefly address our pre-commercial planning activities after which Frank Ruffo, our CFO will review our financial results and 2017 guidance.

After our prepared remarks, we’ll open up the line to take your questions. Chris Powala, our Chief Operating Officer; and Dr. Stuart Shanler, our Chief Scientific Officer will also be available during the question-and-answer portion of the call. 2016 was a transformative year for Aclaris.

During the year, we made significant progress on all of our programs, enabling us to enter 2017 with a solid foundation and continued momentum as we head towards the goal of becoming a fully integrated biotechnology company. Let me recap several of the key milestones from 2016 starting with each of our three clinical programs.

First, at the start of 2016, we initiated the Phase 3 clinical program for A-101 40% Topical Solution for the treatment of SKs. As a reminder, A-101 is being positioned to the cash-paid minimally invasive procedure that will be performed in the physicians’ office.

The Phase 3 clinical program consisted of two randomized, double-blind, vehicle-controlled trials known as SEBK-301 and SEBK-302 and an open-label safety study known as SEBK-303. Patients in 301 and 302 received up to two treatments of A-101 40% during the course of the trial.

The three trials enrolled a total of almost 1,100 patients across 44 centers in the U.S. In November, we reported positive top line results from both Phase 3 trials. A-101 achieves statistically significant and clinically meaningful results on all primary and secondary endpoints. A-101 40% was also well tolerated.

There were no treatment-related serious adverse events in the rates of hypopigmentation, hyperpigmentation, and scarring classified as greater than mild were less than 1% in all groups. Last month, we submitted a new drug application, or NDA to the FDA for seborrheic keratosis.

We have planned for a 12-month review and are hopeful that we will receive approval in the U.S. in early 2018. In addition, we plan to file in the European Union in the second-half of 2017. Moving on to common warts.

As a reminder, WART-201 was a randomized, double-blind, vehicle-controlled Phase 2 clinical trial designed to evaluate the safety and dose response of two concentrations of A-101 Topical Solution, 40% and 45%, compared with vehicle in patients with common warts. 98 patients were enrolled and patients received treatment once a week for eight weeks.

In August, we reported the top line results of the WART-201 trial, in which A-101 45% achieves statistically significant and clinically meaningful results on all primary and secondary endpoints. A-101 45% was also well-tolerated.

The local skin reactions were similar to placebo and most frequently reported local skin reactions across the treatment groups was mild erythema. In addition, we also followed the patients for three months post the last treatment to assess durability. In the 45% group, only one wart recurred, demonstrating a durable response with this treatment.

Given the safety and efficacy demonstrated in this Phase 2 trial and following an FDA guidance telecon, we intend to develop A-101 45% solution for common warts and plan to initiate Phase 2b trials later this year.

In the Phase 2b program, we intend to have the patients apply the drug and will position the product as a prescription meant for at home use. This brings us now to our Janus Kinase or JAK inhibitor portfolio with which we are targeting multiple dermatologic diseases, including alopecia areata, vitiligo and androgenetic alopecia.

Late last year, we submitted an investigational new drug application, or IND and began a Phase 1 human pharmacokinetic/pharmacodynamic trial for ATI-50001, the oral formulation of our JAK 1/3 inhibitor.

We expect data from this trial in the coming weeks and are planning to initiate a Phase 2 dose ranging trial in patients with the most severe forms of alopecia areata, alopecia totalis, and universalis in the second-half of this year.

For ATI-50002, a topical formulation of a JAK 1/3 inhibitor, we plan to initiate a Phase 2 dose ranging trial in patients with the patchy form of alopecia areata in the second-half of this year as well.

In addition to advancing our JAK inhibitor program for the treatment of alopecia areata, as we reported on our last call, we have initiated preclinical development of additional JAK inhibitors, which we’re developing for topical use, both in vitiligo and androgenetic alopecia.

We also plan to initiate a clinical trial with the topical JAK inhibitor in vitiligo in the second part of this year. As a reminder, in addition to our portfolio of JAK inhibitors, our intellectual property portfolio includes method of use IP directed towards the use of JAK inhibitors in a variety of hair loss disorders. We have initiated U.S.

patent directed to methods of treating alopecia areata, androgenetic alopecia, and other hair loss disorders by administering ruxolitinib, and a recently issued patent in Japan directed to pharmaceutical compositions comprising ruxolitinib, baricitinib, or other JAK inhibitors for use in treating alopecia areata, androgenetic alopecia, and other hair loss disorders.

We look forward to keeping you updated on additional progress during the course of the year. Now, I would like to turn the call over to Brett Fair, our Head of Commercial to discuss the pre- commercial activities of the past year.

Brett?.

Thank you, Neal. Good morning, everyone. As Neal mentioned, we’re very excited about the recent NDA filing and the opportunity to launch what would potentially be the first FDA approved drug for seborrheic keratosis.

We believe that A-101 represents an evolution of care in the treatment of SK, which is the most common benign skin lesions seen by dermatologists. With over 80 million sufferers, SK is a highly prevalent condition treated by a targeting group of physicians. However, an unmet need exists in the market as there are no FDA approved drugs.

And current SK treatments are invasive, often painful, and could result in scaring or dis-pigmentation. As a majority of patients at SKs located in cosmetically sensitive areas. These outcomes can lead to poor patient satisfaction.

To-date, we have done market research in more than 500 dermatologists and 1,400 patients testing our target product profile.

In light of the Phase 3 trial results included in our NDA file, we’re confident in our ability to deliver our comfortable and effective treatment option that offers good cosmetic outcomes for patients paying out of pocket for SK removal. Moreover, A-101 is non-invasive, therefore, patients can expect less downtime.

We expect these attributes to translate into higher patient satisfaction with SK treatment. In terms of the overall dermatology market, we see the dramatic increase in minimally invasive aesthetic procedures in recent years being a favorable dynamic supporting the commercial launch.

In terms of launch readiness, we’re well ahead in our planning process and feel confident in our ability to successfully launch the product. Over the last year, we have assembled an industry-leading team with a successful track record commercializing innovative treatments in the field of dermatology.

To-date, we have a clear path on the distribution model and have identified our target audience. We expect to have our sales force alignment finalized by midyear and have already made excellent progress with respect to our campaign development.

Key activities includes framing and refining our practice model, which will enable us to effectively pull the product through our target offices. We will also begin building on our training platform in anticipation of our sales force launch.

In Q2, we will continue to build out our commercial infrastructure as we look to hire and direct our sales operations, training manager, and a dedicated manager of trading customer service, who will oversee our product distribution and related activities.

As we have previously stated, we will look to have our sales managers on Board by early Q4, with a goal of recruiting and extending contingent offers to sales reps by the end of the year. We are confident that our extensive experience and deep relationships in dermatology will enable us to attract the very best talent.

In parallel with our infrastructure build and launch readiness activities, we continue to have a strong presence at various dermatology meetings, raising the awareness of Aclaris in dermatology and shining a light on the significant unmet need in the treatment of SK.

The feedback we have received of these various meeting, including the most recent AAD in Orlando strengthens our confidence that A-101 represents an evolution of care in the treatment of SK. In summary, we see a significant market opportunity.

In considering our Phase 3 results coupled with the progress our commercial team has made thus far, we are very optimistic about the launch potential for this product. With that, I’d like to turn the call over to Frank Ruffo, our CFO to provide an overview of the financial results for the year.

Frank?.

Thanks, Brett. Good morning. As I walk through our fiscal 2016 financial results, please reference the financial tables that can be found in today’s press release. As many of you are aware, during the fourth quarter of 2016, we raised an additional $98.2 million in net proceeds from our follow-on offering of common stock.

As a result, as of December 31, 2016, we had approximately $174 million in cash and investments, which we believe is sufficient to fund our current operating activities to, at least, the end of 2018, without giving effect to potential new business development transactions, or financing activities.

For the full-year of 2016, our operating expenses were $48.6 million compared to $20.7 million for the full-year of 2015. Our operating cash burn for 2016 was $34.6 million versus $20.4 million for the prior year.

It should be noted that our previously mentioned 2016 operating expenses included $6.1 million in non-cash stock-based compensation and the benefit of from $7.4 million in other non-cash charges and increases in networking capital.

On a quarter-over-quarter basis, our total operating expenses for the fourth quarter of 2016 were $11.6 million compared to $4.8 million for the fourth quarter of 2015. Our operating cash burn for the most recent quarter was $8.1 million. R&D expenses increased by $4.5 million in Q4 2016 compared to the prior year.

This was primarily attributable to an increase of $2.2 million in expenses associated with our JAK inhibitor programs and a $1.4 million increase in expenses for our A-101 programs in SK and common warts. We also had a $1.1 million increase in personnel-related expenses, including stock-based compensation, mainly due to increased headcount.

General and administrative expenses for the fourth quarter 2016 increased $2.3 million compared to the same period in 2015. The quarter-over-quarter increase was primarily attributable to a $1.4 million increase in personnel-related expenses, including stock-based compensation due to increased commercial and administrative headcount.

We also experienced a quarter-over-quarter increase of $800,000 in 2016 for market research related to pre-commercial activities for A-101, offset by $350,000 decrease in expenses for patent and prosecution costs related to the JAK inhibitor technology acquired in the fourth quarter of 2015.

Net loss attributable to common stockholders was $11.5 million for the fourth quarter of 2016, compared to $4.9 million for the same quarter in 2015, and $48.1 million for the full-year of 2016 compared to $23.1 million for the full-year of 2015.

Net loss attributable to common stockholders for the fourth quarter and the full-year of 2015 includes approximately 200,000 and $2.6 million, respectively, and accreted cumulative dividends and issuance costs on our pre-IPO convertible preferred stock.

These preferred shares were outstanding until the close of our IPO on October of 2015, at which time they were converted into common shares. Now turning to our 2017 financial outlook.

We estimate our net cash burn for 2017 to be in the range of $65 million to $70 million without giving effect to potential new business development transactions, or financing activities.

We estimate that our 2017 operating expenses to be in the range of $84 million to $92 million, or $70 million to $75 million when excluding estimated stock-based compensation expense.

We anticipate 2017 research and development expenses to be in the range of $51 million to $58 million, or $46 million to $52 million when excluding estimated stock-based compensation.

As of December 31, 2016, we had roughly $26.1 million shares of common stock outstanding, and assuming no material issuances of equity, we would expect our full-year 2017 weighted average share count to be about $26.3 million. With that, I’ll turn the call back over to Neal for a few closing remarks..

Thank you, Frank. Clearly, 2016 has been a pivotal year for Aclaris, as we continue to generate clinical data on our lead development candidates, build out one of the most experienced teams in dermatology and advance our pipeline.

We have built a solid foundation in 2016 and look forward to continue to innovate in whitespace areas within both aesthetic and medical dermatology. As a biotechnology company co-founded by dermatologists, Aclaris is excited to continue to provide leadership within dermatology supporting both physicians and their patients.

Dermatology patients are at the heart of everything we do and our goal is to empower patients by bringing novel, medical, and aesthetic dermatology treatments for conditions, characterized by large underserved patient populations for which there are no FDA approved treatments, or where significant treatment gaps exists.

Thanks for being on today’s call. And, Krystal, can you please pole for questions..

Thank you. [Operator Instructions] And our first question comes from Seamus Fernandez from Leerink. Your line is open..

Thanks very much for the questions. So quickly, Neal, can you just update us on the timing of when the Phase 2 JAK studies, not just will start, but when we could see some endpoint data? I believe previously you guys had said that we could anticipate that in the first-half of next year? Second question, just broadly for the team.

Coming out of the AAD, what was your sort of the general feedback that that you guys got out of the dermatology meeting on the opportunity for the JAKs and how utilization is sort of emerging in that space and their enthusiasm for that class, as well as the kind of feedback that that you’re getting on the the appropriate and national target patient population for A-101 and how physicians are really going to utilize A-101, particularly given the aesthetic – the potential aesthetic benefits? Thanks, guys..

Yes. Thank you, Seamus. I appreciate the question. So on the first in terms of guidance relative to our JAK inhibitor program, we intend to kick off three studies. So two will be for alopecia areata, one – the first one will be oral treatment and that will be for – we think of kind of the severe alopecia areata patient.

We think of totalis and universalis with more expensive hair loss. And then we will kick off a second study on the topical front, again, kind of mid – in mid-year, both of these will kick off simultaneously, and that will be in patients with patchier disease.

And we anticipate having results on both of those trials in the first – late first-half of 2018, as you mentioned. And then we also intend to kick off what we’re thinking of at the moment is more of an open label study for a topical program in vitiligo in the back part of this year.

And we would anticipate having data on that in the beginning of 2018, as well as the first-half. So those are the three JAK inhibitor programs that we’re thinking about at the moment.

And then coming out of – to your second question, coming out of AAD and looking at kind of general feedback, I think, obviously, when you get – when you’ve got an anti-inflammatory class like JAK inhibitors and it could be potentially broadly applicable across a number of indications, what you really need to do is think about what indications are the best route to go.

And in our opinion going after alopecia areata and vitiligo, which are true whitespace with nothing approved in the category, we think makes a lot of sense. I think there was a lot of excitement, a lot of meetings and presentations about those particular indications.

But also psoriasis, atopic dermatitis, some other inflammatory-based diseases as well. So I think there was absolutely a buzz about the category and then it just comes down to picking the right molecule for the right risk benefit profile.

In terms of the feedback around SK in the patient population, I think, we have consistently heard not just at the AAD, but across all of the ad boards that we’ve conducted that kind of going after face and neck as the beachhead for this, given the aesthetic nature of the lesions in those regions makes the most sense.

And we’ve got a lot of positive feedback from both aesthetic physicians and also the medical dermatologists. And there’s a defined profile that, we think represents the target. And we’ve consistently said that, we think our target market – target physician there’s the 3,200 docs about 30% of the prescribers out there.

And they’re the ones who see patients with a lot of SKs. They have SKs in aesthetically sensitive areas, and they have people who are willing to pay. And that’s just a few of the parameters, by which we kind of grade whether somebody is a target. And so that that’s how I would summarize it.

I think there’s a lot of buzz, a lot of positive feedback across the Board – across the whole portfolio in addition to common warts. We’ve also got a lot of interest in that product as well..

Thank you..

Thank you. Our next question comes from Louise Chen from Guggenheim. Your line is open..

Hi. Thanks for taking my questions. So my first question here is on the OpEx progression throughout the year.

I know you gave some guidance here, but how should we think about that? And then on SK for the patients, if your product is approved, what would be the out of pocket cost for a patient that has a large amount of lesions, and how much would the patient pay, and then what the physician make on that? And then lastly, here is just on the lesion itself, once it’s been removed, will it ever come back, just curious if we should think about patients being recurring patients to the doctors? Thanks..

Okay. So I’ll let Frank handle the OpEx, and then I can jump into your second two questions..

Thanks, Louise. From an OpEx standpoint, we just came off of a quarter of $11.6 million in operating expenses, and about $2 million of that was non-cash in stock-based compensation. So rolling forward, that stock-based compensation will be a large amount, again, that’s all non-cash.

And I think you can expect that progression to go – to increase by a few million in the first quarter and then sequentially by a couple of million each quarter as you roll out through the year..

And what about the R&D progression?.

Specifically on R&D, I think you’ll see a significant ramp up early in the year as it relates to the JAK program. As we said before, we’re investing significantly on the JAK program, and that program will likely double in expenditure this year.

Other expenses in that area will – that will increase significantly would be our medical affairs, spending for disease awareness and other medical affairs initiatives. So you’ll see that grow significantly.

But on the A-101 for the warts and the SK, obviously, being through Phase 3 on the SK trial continuing on the wart trial, we’ll see that number dip a little bit.

So on a progression standpoint, I think it’ll be comparable to the progression on total op expenses, increased by a couple of million early in the year, and then sequentially as you roll out to get to that $51 million to $58 million guidance, you’ll see that increase by a couple of million each quarter..

Thanks you. And our next question comes from Liav Abraham..

There’s a second question..

Sorry, one before we get to that just answer the last two questions that Louise had. Once you remove these lesions, they don’t come back. So it’s actually a pretty durable response.

Although if you’re prone to getting more SK lesions that patient, as an example, if they had 20 and you remove them today perhaps by the end of the year, they would start getting more lesions. So although, it’s a durable actual removal when you treat an individual lesion that patient is still prone to getting additional lesions.

So there is a kind of recurring nature to the indication. And then to your second question, when you think about out of pocket, as you treat more lesions the cost goes up. We’re continuing to work on our pricing model. We have started to think about guidance related to the cost per applicator.

Certainly, when you talk and I think your question was pertaining to large numbers of lesions. We’ve always defined that segment as a patient with a full back. That’s certainly a more premium price point, because you’re creating a more dramatic response. You’re clearing potentially a full back.

So, I think, we will be providing more formal guidance around pricing towards the back part of the year. But in general, physicians the cost – whatever the cost of the doctor is marked up by about a 100% to the patient net-net..

Thank you. Our next question comes from Liav Abraham from Citi. Your line is open..

Good morning. Just a couple of questions on your SK compound.

Can you just remind us the percentage of patients seeking treatment today for lesions on the face and neck versus the back? And then secondly, if you could help us think about how you’re thinking about a launch trajectory at this point, given the feedback that you are receiving from the various constituents whether it be payers, physicians and patients? And then lastly, just on your capacity for business development activities, to what extent do you have capacity, both, I guess, from a financial perspective, but also from a people and capabilities perspective? And what type of assets would you be – will you be looking for at this stage, medical derm, aesthetic derm, like what stage of the development? Thank you..

Thank you, Liav, for the questions. In terms of the patient seeking treatments, we have consistently gone through this filter of an 83 million prevalent population out there with 18.5 million patients coming in looking for both diagnosis and treatment.

And then currently with the suboptimal surgical options that we have, we’re seeing about 8.3 million procedures. And so out of that, when you think about those who have lesions on the face and neck, we know that patients who have SKs, 80% of them have lesions on the face and neck.

So it’s a number that’s consistent with the 85% that have them on the trunk. So kind of equal split between face, neck and trunk. Once you are prone to getting these lesions, you tend to get them globally and certainly in sun exposed areas. In terms of the launch trajectory, we haven’t really provided any formal guidance around that.

We are still working on the pricing model and we have a pretty good idea of who our target audience is. I think, one can look to other minimally invasive procedure launches and start to get a good kind of range or bracket around what that might be. And certainly, as the year wears on, we’ll look to provide more specific guidance around that.

Relative to your third question on capacity for BD, we’ve done a lot of work this year and certainly for last year and certainly into this year already scaling up our capacity on both the R&D and also the commercial front. We have historically always been quite active on the BD front.

We are looking for both medical med derm and aesthetic opportunities. Our preference is to go into whitespace areas, particularly on the med derm front. We would rather be kind of the first in the category, particularly with all the reimbursement headwinds, definitely a preference for clinical stage assets.

And I think on the kind of capability front, we’ve added a lot to the R&D side of the house. And right now, we’ve got four programs ongoing in warts and three in the JAK inhibitor side. So we feel like, we’ve been able to build a really robust team and we’re excited..

Great. Thank you..

Thank you. [Operator Instructions] And our next question comes from Tim Lugo from William Blair. Your line is open..

Hi, thanks for the question.

For the next Phase 2 in warts, are you going to enroll pediatric patients? And have you had any feedback from the agency around using the PWA versus clear – near clear endpoint? And also, are you going to treat one wart per patient, or are you going to move it all into multiple warts?.

Yes, thank you, Tim. Good question. So the next Phase 2 that we’re going to embark on, we did – we are refining the physician wart assessment scale. At the end of the day to win in warts, you have to get to the clear. So it’s kind of a binary process.

So the PWA, I think, is more about getting the right kind of range of sizes of warts and just thinking about the inclusion/exclusion criteria there. But the reality is it’s just got to get to clear. And in terms of the number of warts, there was one of the questions that we’re trying to get clarity on we had a guidance telecon.

We think it’s going to be multiple. Our feeling at the moment is that, we’ll be treating a range of warts from about one to three per patient and that’s what we’re planning on for the Phase 2b at the moment..

Okay. And maybe for the JAK program, your three studies kicking off, it sounds like before year-end.

Are any of them going to have placebo arms? And in general, how should we think about placebo rates? I think it’s variable between the patchy alopecia areata patients versus the more severe patients?.

I’m sorry, I missed that question, Tim.

Can you just repeat that?.

Oh, yes sure, sorry.

For the three JAK studies kicking off, are you going to use a placebo or vehicle arm in any of them? And in general, what should we think about placebo rates in the indication?.

Yes. So and going back, I don’t think I answered your other question on the wart study going into peds. We will go down to 12-year olds, so….

Okay..

So that will be encompassed in that study. On the JAK inhibitor front, yes, there will be placebo arms. It’s – whenever you have hair loss studies, I think, the placebo rates are generally a little bit lower although, because it is a more objective kind of objective process. But when you think about alopecia areata, there is a stress component to it.

So that if somebody is certainly enrolling in a study and believes that they may or may not be on drug, you could – you might expect a little bit higher placebo response rate in areata, then you wouldn’t say like a male or female pattern hair loss tough to us – for us to kind of really guess at that at the moment.

But I think, we feel pretty comfortable it’s going to be lower than in most derm indications like say in atopic dermatitis..

Okay. Thanks for all that..

Thank you. And I’m showing no further questions from our phone lines. I would now like to turn the conference back over to Neal Walker for any closing remarks..

I think, yes, so I appreciate everybody joining the call today. We’re excited about what 2017 will bring. We’ve got a lot of programs kicking off this year.

We’re excited about the transition to a commercial stage company on the SK front, and we’re really excited about developing our full JAK inhibitors estate across three indications, and I appreciate everybody’s time..

Ladies and gentlemen, thank you for participating in today’s conference. This does conclude the program. You may all disconnect. Everyone have a wonderful day..
