With that, I will pass the call over to Maria.

Thank you, Tim, and good afternoon, everyone. Iovance continues to make excellent progress in development of TIL therapy. We are excited to potentially become the first company bringing TIL therapy products to market for patients with solid tumors. I’d like to briefly highlight a few recent achievements. First in June we reported encouraging results from our ongoing studies of TIL therapy at the American Society of Clinical Oncology or ASCO Annual Meeting. The results that were reported in both metastatic melanoma and advanced cervical cancer showed objective response rates that is represent improvements relative to available treatment options and late stage take late stage patient populations. The results also show the potential long-term benefit of TIL therapy as we have not yet observed a limit on the median duration of response in either the melanoma or cervical cancer study. Second, we are working to expand our manufacturing capabilities to prepare to meet TIL therapy broadly accessible to patients. In May, we entered into a long term lease agreement to build a commercial scale production facility in Philadelphia and in June we began construction. Third, our cervical cancer program is moving forward and an accelerated pace. We are extremely pleased to have received a Breakthrough Therapy designation from FDA for LN-145 and we now plan to submit a biologics license application or BLA for TIL therapy, LN-145 in late 2020. Now I will discuss these development program in detail and provide an update on our corporate activities as we prepare to potentially commercialize while we further continue to evaluate the broad potential of cell therapy in clinic. Our pivotal study of TIL therapy with lifileucel and the treatment of metastatic melanomaC-144-01 is progressing well. The results we presented at ASCO shows that lifileucel demonstrated an Objective Response Rate or ORR of…

Thank you, Maria. Our quarterly news release contains details of our financial results. Rather than read through all these details my comments will address a few highlights. Net loss for the second quarter 2019 was $47.6 million or $0.38 per share compared to a net loss of $30.7 million or $0.34 per share for the second quarter last year. The increase in net loss for the quarter as compared to last year was due to higher spending as we continue enrollment in the pivotal study prepare for the BLA filings and eventually commercialization. Specific higher expenses are due to increased headcount in both R&D and G&A. At quarter end we had approximately 120 employees as compared to approximately 75 at June 30, 2018, increased spending on market research for both melanoma and cervical, additions to the IP estate and patent portfolio in the U.S. and worldwide, an increase in manufacturing capacity in the U.S. and Europe. Research and development expenses were $39.3 million for second quarter 2019 an increase of $14.7 million as compared to $24.6 million for the second quarter 2018. General and administrative expenses were 10.9 million for the second quarter an increase of $4.1 million compared to the $6.8 million we had for the second quarter 2018. Enrollment in the pivotal melanoma and cervical study has increased as compared to last year and over the first quarter this year. We have increased manufacturing capacity to support this enrollment. We also added headcount and begun pre-commercial activity in anticipation of BLA filings for these programs in late 2020. We anticipate that the level spending for the second quarter 2019 will continue at this level on a quarterly basis until enrollment in the pivotal studies is completed. Net loss for the six months ended June 30, 2019 was $84.5 million or $0.68 per share compared to a net loss of $57.2 million or $0.65 per share for the period ended June 30, 2018. The increase in net loss for the first half of 2019 as compared to the first half of 2018 is due to the reasons discussed above for employees, market research, new IP an additional manufacturing capacity. Research and development expenses were $70.2 million for the first half of 2019 and increase of $25.7 million compared to $44.5 million for the same period ended in 2018. General and administrative expenses were $19.9 million for the first half of 2019 and increase of 6.1 million compared to $13.8 million for the same period in 2018. At June 30, 2019 the company held $410 million in cash, cash equivalents, short-term investments and restricted cash as compared to $440 million that we had at March 31, 2019. During the second quarter the company used $34 million for operating activities. The company anticipates that the year-end balance of cash, cash equivalents, short-term investments and restricted cash may be between $310 million and $320 million. I will now turn the call back over to the operator for your questions

[Operator Instructions] For your first question we have Mark Breidenbach from Oppenheimer. Your line is now open.

Congrats on this very rapid progress and thanks for taking the questions. Just first one about timing relative timing of melanoma versus cervical. Do you sound like they are both going to be ready for BLA filings towards the end of 2020? If you had to guess which one would come first could you do that at this point or they'd be either too early to tell?

Hi, Mark thank you for the question, I don’t know if I can necessarily say quite yet. I do want to highlight that we are also continuing to work with FDA to assure our cervical sample size is in line with their expectations. We think we are fairly close with the numbers. We want to make sure that we continue that dialogue. I can tell which is why we put sort of that late 2020 and frankly so within a month or two of each other there is a very good chance that we might want to combine them or that agency asks us to combine them. Somewhere around that late 2020 I think both of them could possibly be filed.

And also another timing question with respect to the new manufacturing facility. Obviously construction was started relatively recently can you just remind us when you expect it to be fully operational and have you given us any indication on capacity for this facility in terms of number of batches or doses per year it can accommodate?

Yes, we have expected it to be operational in about two years and our expectation is thousands of patients can be supported through this facility. It is a butterfly design in a sense that half of the facility is expected to the operational supporting our initial year or two of commercialization. And then subsequent to that the rest of the facility can also get opened up. So it's capable of increasing capacity as necessary.

And so in the meantime, if you have approved products before that’s operational but they will be supported by your agreements with third-party manufacturers?

That’s exactly right, so initial manufacturing plan could be done through our existing CMOs while the facility get ready.

And just one last one from me if that's okay, any plans to conduct internally blinded independent reviews of responses either from Cohort 2 and the melanoma trial or the initial cervical data that you presented at ASCO?

I can answer the second part maybe more easily, anything going forward now that the agency has agreed the study is pivotal likely will not be done in a public setting. So the cervical data will be read by BIRC but probably will initially be disclosed to FDA before further publication. Cohort 2 BIRC is something that we are working on just to make sure that we have a very clear process with our BIRC. We have not made a commitment of timing of disclosing that data given that Cohort 2 is just supportive from a FDA perspective, but yes we are working in that front as well.

Okay, fantastic thanks again for taking the questions and congrats on all the progress,

Thank you, Mark.

Your next question is from Biren Amin from Jefferies. Your line is open.

Thanks for taking my questions. Maria maybe if I could just start on the cervical cancer cohort that you presented at ASCO. How many of the 27 patients that were presented at the meeting will be counted towards the pivotal trial, because I think previously you said that - you may have had a very few patients who may not have advanced disease?

Almost all would qualify, we have not broken down, as I’ve noted when a study is pivotal we intent to release very little data, really we should provide that data to FDA first. So we have not broken it down by specific line of therapy but almost all of them would qualify with this new patient population definition.

And then just on timelines, I believe you previously commented that the cervical sample size should be in line with FDA just want to ask around that because I think in your press release you tightened enrollment, previously it was 75 to a 100 patients and now its just 75 patients. So I guess what drove this modification?

We continue the dialogue with FDA and we want to be sure that we have complete alignment. In the meantime, the study itself had 59 in there. So we wanted to be sure that we have enough runway while we continue the discussion with FDA, so that’s why we amended it to 75 while we continued the dialogue.

Okay. And then maybe one more, I noticed that you plan to complete enrollment for the melanoma cohort in Q1 2020 and given you may have overlapping timelines across both indications, should we assume that the cervical cohort with complete enrollment in Q1, 2020?

It’s a reason or expectation Biren, I think it has to do with our completion of the dialogue with the agency whether they agree with 75 sample size, but that did high level assumption that we are pursuing right now, but again, it depends on our completion of the discussion with FDA.

Your next question is from Madhu Kumar from R.W. Baird. Your line is open.

So one thing we've been kind of thinking about a lot is how physicians consider the use of IL-2 as part of the TIL administration procedure and when you talk to physicians in your market research, what has been the kind of feedback on the use of IL-2 and to what degree do you think kind of improving the perspective of between oncologist will occur through education versus technologies, so in method they don't rely upon kind of the use of high-dose IL-2 even if it's at a different dosing duration than the standard approved usage?

Thank you, Madhu. Maybe a couple of points before sort of talking about the hustle experience. The median number of doses for melanoma and cervical one was 5.5 and one was 6. So administration of IL-2 didn't seem to be an issue both for the patients tolerance perspective as well as the hospital infrastructure. It’s important that we note that we are in hospital setting for just about all of our clinical trials sites or hospitals most of these sites have already been using IL-2 and in fact many more sites have been using IL-2 in the past five years. At the footprint of IL-2 has been at 100 and 150 or so different type as late as about five years ago. So there’s a lot of trained staff at most of the hospitals that have administered IL-2 and they are comfortable with it. So we have not really run into an issue where we want to activate a site and they had no staff that had been trained on IL-2.We also definitely help with any refreshments in terms of training to administration of IL-2 as well, so that hasn’t really come up as an a showstopper issue for us. It seems that most of the hospitals that we're in have the training staff to support that administration.

And then my other question is are there any expectations for data in the next six to 12 months that would be reasonable, I mean, obviously you can't speak hard and fast but would there be any more data from anything ongoing clinical programs over the next year or so?

Yes. We do have other studies beside the two pivotal programs. We certainly code have data on Cohort 2 if there is any new information to be shared or other indications all ongoing. So we have not excluded a possibility of trying to put some data out, particularly when there was more like the 12 months timeframe, but we haven’t committed to anything that’s I guess that helped you look at it.

Okay, follow up on that last point. When you said, you have more additional Cohort 2 melanoma data if there is new information, what would you define as a new information from that cohort?

I can define a couple of at least two different directions is we have for example, a DOR that is reached if we have specific biomarkers that maybe appearing upon further investigation or thinking about for example, even in the case of cervical, the clonality of distribution of clonality of cervical all of those are interesting exciting things that we still continue looking at. There is a combination of how much data maybe coming as well as what venues are available that may be interested in hearing about them. I know the investor community is very interested in the details of the data, academic institutions are more interested in putting brand new sort of directions for research out in various conferences. The conference is a respective to something that may be more different than just ORR deal that we have published before. So there needs to be a venue where we feel is appropriate to disclose the data. But there is definitely ongoing investigation in a Cohort 2 as well as our other indications that we think are exciting and we learn something new about them every day. We could put that information out.

Cohort 2 below - would the absence of this [indiscernible] Cohort 2 then because we opt the corollary that the DOR has not been recently DOR haven’t reached?

It could also vis-à-vis might have considered a conference and the conference did not seen just adding a DOR was adequate enough to get into that conference. So I wouldn't read too much into it.

Your next question is from Joe Catanzaro of Piper Jaffray. Your line is open

Maybe I’ll follow-up and just ask the question a little differently and thinking more about near term data disclosure. So I believe today is actually the deadline for [SIPSI] regular abstract submission have you guys submitted anything to SIPSI?

I usually don't comment on what we have submitted or we intended to submit until titles or abstract itself is released. Sorry, Joe, I prefer that we know what we can talk to if that’s okay. We’ll wait until the titles come out.

Fair enough. Just thought I'd ask. My next question, so I believe you had mentioned maybe later last year the idea of taking an interim look at Cohort 4 melanoma whether the FDA would agree to that. Was that ever built into Cohort 4? And then along those lines as is there a similar opportunity in cervical to take an interim look if you believe your 95% confidence intervals will exceed that lower down hurdle?

Yes, we just think about it for a moment in time. I think that as cervical is becoming potentially a component of this package we prefer to transfer all of them together not to have multiple cost on the data. So today’s preference for me would be to read both studies, both cohorts of the studies at the same time and try and see if we can provide FDA with the totality of the data. That would be a more preferred path for us.

And then maybe just one more quick one here. I am wondering if you've noticed any pickup involvement into your cervical trial since the ASCO data disclosure?

In operations of the study typically we see weighs our patients coming and going, so we’ve definitely seen increased enthusiasm. I think one of the points that Tim made in our increase spend is reflective of our increase in R&D. There have generally been a lot more enthusiasm recently in entire TIL program that I can say.

Okay. And maybe I’ll just squeeze in one more here along the same lines just in regards to the head and neck trial. I know you guys had some struggle with enrollment there and I know it's still the early days of the recent KEYTRUDA label extension in the front line setting, so the window is short. I am just wondering if you have any comments around what you're seeing in head and neck right now?

Yes, we have very good observation. I agree that I believe the landscape of head and neck is changing and hopefully for the better for the patients, ideally the patients would have seen chemo immunotherapy in the front line and hopefully then the patients was coming to study as opposed to third or fourth line when patients are quite late line at that point. So we are beginning to see that trend, although it is as you noted, it is early in that landscape shift in a meaningful way. But yes, we are beginning to see that pattern.

Your next question is from [indiscernible]. Your line is open.

Congrats again on the progress and thanks for taking my question. So kind of searching on the same theme with the potential BLA filing for melanoma and cervical in place. Could you speak a bit for the kinds of preparation that you’re making for the filing and to what extent there is overlap for the two programs and then I have a follow-up after?

Thank you, [indiscernible] for your question. It’s a little hard to hear you, but I think I understood that you are asking what kind of preparation the organization is going through in anticipation for filing?

Yes.

Thank you, there is quite a bit that an organization - that maybe thinking about a filing next year has to go through both from an infrastructure perspective short-term and long-term both procedurally as well as - and from a growth perspective. So you can imagine that from a procedural perspective various documents need to be finalized, need to be put in place. And lot of different hiring needs to be had including the team members in commercial medical affairs being expanded, market access, market research is undertaken. So a significant amount of activities are undertaken in anticipation of both filing as well as a potential commercialization. And we are certainly on track for initiation of many of those works stream.

Great. And then now that we have a sense that the regulatory plans in the U.S. you’ve mentioned that kind of Europe is on the horizon. Is there any further visibility in terms of next steps towards putting together a path in Europe and what are some of the consideration that might be different there versus the U.S. for the two programs on whether you might kind of advance them together or separately?

Definitely, so we have been thinking about engaging the EMA in a more centralized procedure, but we want to make sure that we wrap up all of our FDA discussion around cervical sample size agreement around the protocol before we engage EMA. It’s always easier when we have at least a set of agreement in one health authority before we go to the second health authority. It’s very much on our horizon. And we are very excited about the fact that we have a fairly broad footprint in our clinical program in Europe, but for a centralized procedure we think that’s likely more towards later part of this year and earlier part of 2020.

Your next question is from Boris Peaker from Cowen. Your line is open.

So first question I want ask - is on the cervical indication. I am just curious what specific patient enrollment criteria that the FDA want to see in the pivotal study that ended up excluding some of the patients that we saw at ASCO?

Our initial enrollment criteria was patients who have received one prior systemic therapy. And while bulk of these patients are in the metastatic setting, not everybody necessarily has seen a systemic therapy in a metastatic setting. So the definition was a little tighter after the discussion with FDA to assure that they have seen that one prior systemic therapy in the metastatic setting that was their clarity.

And what’s a non-systemic therapy it just means just localize surgery without adjuvant treatment is that what that is?

A localize therapy can be applied in curative setting for example. It could have been a surgery combined with radiotherapy for example or it could be surgery along with a systemic therapy. So the definition here is stay in the metastatic setting and not in the curative setting.

My next question is on the manufacturing facility, once it becomes operational and you’ve outlined time of about two years. Would Lonza will still be involved in any way or is that when you Lonza relationship ends and you kind of break off on your own for manufacturing?

Thank you for that. So Lonza is our manufacturer in EU. So if I may rephrase your question I presume you’re asking about [WuXi]?

Yes sorry, I forgot that’s for the U.S. that’s right?

Sure. We intend to continue the relationship with WuXi. WE find it particularly helpful for our tech transfer, process development and our clinical program. So as of now there is no reason that I see for us discontinue that relationship. They will cover our initial commercial landscape and I would like them to stay engaged with Iovance for their commercialization landscape as well. I don't see this program ending just because we are commercial we will always have a development program behind it.

As we have no more questions, we would now like to return to Maria Fardis for closing remarks.

Thank you, Operator. We are glad to have this opportunity to reflect on our progress. We would like to extend our sincere appreciation for the many individuals who support our work including our shareholders, dedicated and talented employees, patients, clinical investigators in their ongoing studies and researchers at our partners institutions already working with us to refine application of TIL therapy. And thank you for all of you joining us on this call today. Operator?

Ladies and gentlemen, thank you for your participation in today's conference. This concludes today's program. You may now disconnect.
