Good morning, my name is Jackie and I will be your conference operator today. At this time, I would like to welcome everyone to the Enanta Pharmaceutical's Fiscal Fourth Quarter and Year end Financial Results Conference Call. All lines have been placed on mute to prevent any background noise [Operator Instructions] Thank you. I would now like to turn the call over to Carol Miceli, Director of Investor Relations. Please go ahead.

Thank you, Jackie and good morning everyone and welcome to Enanta Pharmaceutical's fiscal fourth quarter and year end financial results conference call. The news release with our financial results was issued this morning at 7:30 and is available on our website at www.enanta.com. You can also listen to the webcast or the replay by going to the investor section of our website. On the call today is Dr. Jay Luly, President and Chief Executive Officer, Paul Mellett, our Chief Financial Officer and Dr. Yat Sun Or, our Chief Scientific Officer. Before we begin with our formal remarks, I want to remind you that we will be making forward-looking statements including plans and expectations with respect to regulatory and commercial developments for our product candidates, milestone payments and financial projections, all of which involves certain assumptions, risks and uncertainties that are beyond our control and could cause our actual results to differ materially from these statements. A description of these risks can be found in our most recent Form 10-K and other periodic reports filed with the SEC. In addition, Enanta does not undertake any obligation to update any forward-looking statements made during this call. I’d now like turn the call over to Dr. Jay Luly, President and CEO.

Thank you, Carol. I’d like to welcome everyone on the call this morning. On today’s call we’ll discuss our financial results for the quarter and fiscal year end, provide an update focus on our clinical stage Hepatitis C pipeline, and review progress with our early stage proprietary development programs for HCV. There has been much progress during the quarter and over the past year. We ended the year with $132 million in cash and securities and our lead HCV candidate ABT-450 known as Paritaprevir is under regulatory review in the U.S. and EU. Last week, the CHMP in Europe granted a positive opinion for AbbVie’s investigational 3-DAA treatment regimen for the treatment of Genotype 1 HCV and a positive opinion for the 2-DAA regiment for Genotype 4 HCV. Upon the worldwide regulatory approvals for our partnered HCV assets, we expect to receive up to an additional $155 million in milestones from our partner AbbVie. If AbbVie’s regimen is approved, it will include the first product approved from Enanta’s pipeline and will be the beginning of a series of regulatory approvals anticipated over the next few years that includes Enanta candidates. We have a strong HCV pipeline with two partnered protease inhibitors and three wholly-owned clinical and pre-clinical stage HCV programs and we continue to pursue the growth of our pipeline beyond HCV with ongoing research for candidates and other indications. But before we go into detail about the progress with our pipeline programs, I’d like to stop here and turn the call over to Paul Mellett, our Chief Financial Officer for a review of our fourth quarter and year-end financial results, Paul.

Thank you, Jay. I like to remind everyone that Enanta reports on the basis of the fiscal year end that ends September 30. So, we are reporting results for our fourth fiscal quarter and our fiscal year ended September 30, 2014. Looking at our balance sheet, Enanta ended the year with approximately $132 million in cash and marketable securities as compared to $112 million at our September 30, 2013 fiscal year end. We expect that our current cash, cash equivalent and short and long term marketable securities will be sufficient to meet our anticipated cash requirements for at least the next 24 months. We have new items on our balance sheet consisting of current and long term deferred tax assets totaling approximately $15 million. These represent tax credits and net operating loss carry forwards that are available to offset tax liability that may arise in the future. If Paritaprevir receives approvals in the coming months, we expect to use substantially all of these assets in fiscal 2015. Moving on to our statement of operations, I’d like to point out that our revenue this past year was generated from two primary sources, collaboration revenue earned under our agreements with AbbVie as well as research and development funding earned under our contract with the National Institute of Allergy and Infectious Diseases or NIAID, a division of the NIH. Revenue for the three months ended September 30, 2014 was $2.6 million compared to $1.3 million for the three months ended September 30, 2013, all of which was related to our NIAID contract. For the year ended September 30, 2014 revenue was $47.7 million compared to $32.1 million for the prior year. The increase in revenue for the fiscal year 2014 was primarily due to milestone payments totaling $40 million received from AbbVie for…

Thanks Paul. I’d like to begin by saying there has never been a more exciting time for Enanta. In the highly competitive field of HCV development, Enanta is one of the very few companies poised to be part of the first generation of all oral regimens to treat HCV. Enanta along with their partner AbbVie identified the potent protease inhibitor ABT-450 which is a key component of AbbVie’s regimens on the verge of global regulatory approval. The potential milestone payments and royalties generated by our partnered protease inhibitor programs with AbbVie are expected to fund the advancement of our internal programs which I will discuss shortly and to enable us to explore new disease areas for growth beyond HCV. We have previously spoken about multiple ways of opportunity for product launches. The first wave is ABT-450 as part of the 3-DAA regimen for patients with chronic genotype 1 HCV. This 3-DAA regimen is currently under regulatory review in the U.S. and in Europe where last week it received a favorable recommendation from the CHMP. AbbVie has announced that they expect a U.S. approval for the 3-DAA regiment this year, followed by European approvals in early 2015. Enanta is eligible to receive upto an additional $155 million in regulatory approval milestone payments upon approvals in major jurisdictions. Last month Enanta and AbbVie finalized the percentage of net sales from the new HCV regimen and will be allocated from our protease inhibitors. These allocated net sales will be used to calculate Enanta’s annual tiered double-digit per product royalties. Following regulatory approval and commercialization, 30% of the worldwide net sales of the 3-DAA regimen containing ABT-450 will be used to calculate royalties. We believe the opportunity for this 3-DAA regimen is large, based on strong Phase 3 clinical data demonstrating high cure rates…

[Operator Instructions] Thank you. Our question is coming from the line of Jessica Fye with JPMorgan.

Hey there, good morning. Maybe just more of a longer term question, but in terms of how you think about making investments in your internal pipeline as it relates to the progression of ABT-493. So I guess what I’m getting at is given the economics on that combo to the extent you get greater visibility on the potential success of that asset in cash it could throw off, just how does that factor into your spend decisions? I guess, you are having to put things on hold but just kind of how you think about that?

And to be clear, you are talking about ABT-493?

Yes.

Yes. So ABT-493 based on the decision we made last month we will not be spending our internal dollars for the development and commercialization of that asset since we elected to not opt in to that path. So, instead AbbVie will fund 100% of the development of 493 and the combination studies, commercialization and the launch cost and we will have a worldwide double digit royalty.

I guess what I’m saying is just if that product is successful and AbbVie converts the franchise to a combo that you have put our economics on, and you’ve got more cash coming in the door, does that affect how you invest in your internal assets?

Well that certainly help augment our spend and in a very non-dilutive way. We expect the first revenues to be coming in from the ABT-450 driven regimens first the 3-DAA then 2-DAA and then 493 would be part of that third wave, and by then I think some of our internal programs will have advanced to further into clinical development and as those cost ramp up we expect to cover a good chunk of them through the cash flow that will be coming from ABT-493 driven regimens. That was a big part of why we made the opt in decision the way we did so that we would have rather than plowing our revenues from AbbVie on their first couple of regimens back into the third, we elected to take those revenues and plow it into internal pipeline development HCV and other areas. So, we think it will just lead for a very smooth progression.

Thanks.

Our next question comes from the line of Howard Liang with Leerink

Thanks very much. I have a question regarding the sort of the I guess the presentation of the products. So for 3-D, I think it’s the European recommendation looks like it’s actually two products, EXVIERA the TI [ph] plus NS5A and ritonavir combination single pill as well as VIEKIRAX, which is the remaining components. Can one buy these two separately, and therefore would EXVIERA be priced roughly in line with your revised agreement with AbbVie that is maybe perhaps roughly about two thirds of the total cost of the 3-D?

Yes. So obviously the pricing strategy and discussions around that haven’t been disclosed by AbbVie and in fact, they control setting that price, as you probably know. To answer the first part of your question, they will be sold separately in Europe. They will be approved and sold separately. That will allow them to be comp combined in a 3D regimen for HCV genotype 1 and then to be broken out as appropriate for other kinds of indications including genotype for obviously for the 2D regimen.

Okay. And a follow-up question for 493, 530 combo. When should we expect phase 2b data?

Yes. So the 2b data – the 2b study is ongoing now. We expect to put that data out next year. We haven’t indicated yet at what meeting, but I think you can expect that it will be presented at a Scientific Conference in calendar 2015. We also expect to press right into phase 3s next year as well.

Thank you.

You’re welcome.

[Operator Instructions] Our next question comes from the line of Brian Skorney with Robert W. Baird.

Hi, good morning. Thanks for taking my question. This is Morgan [ph] on for Brian this morning. I just had a quick question regarding the NS5A from Novartis. Can you just kind of clear up the timeline that you’ll have with that in terms of the proof-of-concept study and then what’s next after that? Thanks.

Sure. The proof-of-concept study is wrapping up the final subjects literally right now. And as part of the return of that asset to Enanta, we get -- the IND was initially our IND we assigned it to Novartis and that will be reassigned back to us. The data sets will transfer over to us and drug etcetera. And then, we expect that migration of asset back to us to be pretty much wrapping up by the end of this year. We’re in the thick of defining the development plan next steps for this program and we’re not ready to talk about that yet today, but we do expect we’ll be talking about that early next year.

Okay, great. And you said that the POC study is wrapping up right now. Is Novartis just finishing it up and then handing the data over or are you going to finish up yourselves?

They are wrapping it up and then it will be handed over to us.

Okay.

It’s like the best way to do it rather than transfer at the very end of the trial just doesn’t make sense. So…

Okay, great. Thanks.

That’s the logistics we’re going through. Yep.

Our next question comes from the line of Jessica Fye with JPMorgan.

Hi there. Just to follow-up on that. I guess realizing you’re going to kind of update us on the development plans for 293. Just trying to think about R&D spend for next year even maybe with more details on that, but I know you said, its going to be up, but is there just any kind of more color you can put around how to think about that expense for next year?

So 239 development will add to that will be obviously incremental over what we had spent this year. So it is going to go up. I’m somewhat reluctant to put a figure out there now while we have a development plan moving around a little bit, so, I think we can get better guidance on that next year.

Okay. And is that going to be the main kind of driver of R&D expense sort of incremental expense there?

Well, we have a number of programs. Sometimes it’s anything that moves into the IND enabling stage will clearly add to that. Sometimes IND enabling studies can cost as much or more than phase 1 studies just given all the things you need to do. So, it would be typical and ordinary kinds of things for us as we see it right now.

Thank you.

Welcome.

At this time, we appear to have no further questions.

Okay. Thank you everyone for taking the time to join us on the call today. We hope to provide you with more updates on approvals of the ABT-450 containing regimens in the near future. Thank you.
