Thank you, Chuck, and welcome, everyone, to our First Quarter 2023 Financial Results and Business Update Call. I will begin by reviewing our recent progress and accomplishments. Following my remarks, Eyal Rubin will provide a more detailed review of our financial results. We will then open the line for questions. As we updated earlier this morning, we, together with our development and commercialization partner, Chiesi Global Rare Diseases, are waiting on EC decision, which should be announced in the next couple of days. In addition to the EU, we are also quickly approaching potential approval in the United States. Our signed PDUFA target action date is next week, May 9, 2023, and we look forward to providing you with an update when we hear from the FDA. We are grateful for the Protalix team as well as our partnership with Chiesi that has brought us to this stage. We are confident that if approved, Chiesi is well-equipped to realize the full potential of PRX-102. They have ramped up commercial activities and are prepared for launch. Fabry disease represents a potential significant opportunity in a multibillion-dollar market that is in need of an alternative treatment option and we, together with Chiesi, are prepared to deliver. Now turning to our pipeline. We are continuing to make progress in our earlier stage programs. PRX-115 is a novel PEGylated uricase in development for the treatment of severe gout. In March of 2023, the first patient was dosed in our Phase I first in human clinical trial for PRX-115 in patients with elevated uric acid levels. And the trial is a double-blind placebo-controlled single-ascending dose study designed to evaluate the safety, pharmacokinetics, pharmacodynamics and immunogenicity of PRX-115 in up to 56 patients. The study is being conducted in New Zealand. And to date, 9 patients…

Well, thank you, Dror. And just to make it clear, obviously, the cash runway is until third quarter of 2024. Thank you, everybody, for joining the call today. Let me review our first quarter 2023 financials. We recorded revenues from selling goods of $5.1 million during the 3 months ended March 31, 2023, a decrease of $3.9 million or 43% compared to revenue of $9 million for the 3 months ended March 31, 2022. The decrease resulted primarily from a decrease of $2.7 million in sales to Brazil and a decrease of $1.1 million in sales to Pfizer, both resulting from timing differences. We recorded revenues from license and R&D services of $4.5 million for the 3 months ended March 31, 2023, a decrease of $2.6 million or 37% compared to revenues of $7.1 million for the 3 months ended March 31, 2022. Revenues from license and R&D services are comprised primarily of the revenue we recognized in connection with the Chiesi agreement. Cost of goods sold was $3.1 million for the 3 months ended March 31, 2023, a decrease of $2.9 million or 48% from cost of goods sold of $6 million for the 3 months ended March 31, 2022. The decrease in cost of goods sold was primarily the result of decrease in sales of goods. For the 3 months ended March 31, 2023, our total research and development expenses were approximately $5.8 million comprised of approximately $3.5 million in subcontractor related expenses, approximately $1.5 million of salary and related expenses, approximately $0.1 million of material-related expenses and approximately $0.7 million of other expenses. For the 3 months ended March 31, 2022, our total research and development expenses were approximately $8.8 million comprised of approximately 5.8 million subcontracted rated expenses, approximately $2 million of salary and related expenses,…

So thank you very much, Eyal, and thanks, everybody, for joining us on today's call. I'm sure everybody is under anticipation for the upcoming approvals. Clearly, it's an exciting time for us. We are looking forward to providing you, of course, with the update once we have them, both from the EU and the FDA. And in addition, we are planning on hosting an investor event late June to discuss Protalix's strategic priorities going forward. Now I will turn back to the operator and open the line for questions.

[Operator Instructions]. The first question comes from John Vandermosten of Zacks.

Dror, and Eyal, how are you guys doing?

We are doing fine. Thank you, John.

That's good to hear. Next week is going to definitely be a big week for you guys, so we're all over here looking forward to that. But I thought I would spend a little time on PRX-115, just to understand kind of that a little bit better. I guess you're running the trial in New Zealand, as you've mentioned many times. Are there any incentives that you're getting from running it there? I know that that's a pretty favorable place to do early-stage trials just because the benefits that the Australian and New Zealand government provide developers there.

John, can you repeat? I don't understand the question. What is the question exactly?

Sure. So in the Oceania area, in New Zealand and Australia, I noted frequently that there are very supportive environment in terms of tax benefits and credits and things like that to run trials down there. Is that something that you're benefiting from for PRX-115 down there?

Eyal?

Yes, that's correct, but that's not the reason we are running the trial there. We didn't apply in order to benefit from a tax credit. You need to open an on-site, on-the-ground site there in New Zealand and in Australia. And they obviously are running for at least the Phase I. We saw that it's too big of a burden. The reason was that the CRO that we picked and the sites are -- they have expertise and their enrollment capabilities are good for such reasons that we would pick the site and the CRO.

Okay. Great. And obviously, this is the Phase I where the primary goal is safety. But I wanted to see if you could share some of the secondary end points that you're looking at that might look at efficacy. And then also, if we're successful in these early stages, what might some of the endpoints be for a pivotal trial in terms of efficacy?

So John we planned, as I mentioned, up to 56 patients. And in addition to safety, of course, which is the first thing, we would like to see immunogenicity. We would like to see to what extent we reduce the uric acid, maybe hints or signs of frequency of dosing. So -- but this has to be -- we are at the very beginning. So we will never show off, and there's nothing to show off it right now. So we -- hopefully, we plan to -- once we have the final reports, including the PK/PD to better analyze it and understand how to properly conduct the Phase II.

Sounds good. And the -- one of the major players in gout right now is KRYSTEXXA. And I'm just wondering if you have a comparison of how PRX-115 goes up against that guy.

No. We will have to see results before we can say anything.

Okay. Well, I was thinking in terms of mechanism of action or kind of the unmet need perhaps that 115 may address. Not ultimate efficacy, but just how it might work in terms of the MOA.

By the end of the day, we hope to have a differentiation in at least on an improved profile and in at least in one important aspect. We will have to see if it will be the frequency of dosing, immunogenicity or a combination.

Great. Okay. That's helpful. And last thing for me, just obviously, next week is a huge week. And what are the next steps that we should expect to see? I know you mentioned that there's -- you're going to have a call with investors in another month to go over priorities and things like that. But what are the next steps we should expect to see, I guess, from you and Chiesi in terms of commercialization and getting things ready, assuming we're getting positive news back?

So we will clearly update immediately the market once, hopefully, of course, we get the approval from the EU and following that with the FDA. This is the sequence we see right now, of course, or anticipate. So we will, of course, update and explain. And I'm not familiar with anything else right now. Once Chiesi plan the launch of the product, then we'll update, of course.

[Operator Instructions]. We show no further questions at this time. I'll turn the call back over to our speakers for any closing remarks.

All I have to say, thank you, everybody, for this time. And we are looking forward, of course, to update you very, very soon. Thank you very much.

Thank you. This does conclude the conference call for today. We thank you for your participation and ask that you please disconnect your lines. Thank you. Have a good day.
