Thank you, everyone, for joining today. DELCAP has had a productive third quarter of 2022 for both Hepsodon Kit, the company's product development candidate from the United States, and ChemoSat, the company's marketed product in Europe. In the U.S., we have two centers enrolled in currently treating patients under the Expanded Access Program, or EAP, with a third center enrolled in pending training. In addition, the Four other sites are in various stages of the startup process, and these include sites that were not involved in the FOCUS trial. We are on track to file the Hopsado Class II resubmission of the NDA to FDA by the end of December. We expect that within 30 days after the submission, the FDA will confirm receipt of the submission and, if they agree the resubmission is sufficiently complete to warrant review, establish a PDUPA date six months from the submission date. As we previously reported, In the third quarter, a retrospective analysis of patients treated with chemo sat in three European centers, one in the Netherlands and two in Germany, between February 2014 and December 2019 was published. The analysis involved 212 PSP procedures on 101 patients. The publication reported an overall response rate of 59.4% and a disease control rate of 89.1%. The safety analysis showed mostly grade 1, 2 and self-limiting toxicities. consistent with previous reports on PHP. This continues to add to the growing body of published research documenting the efficacy and safety of our ChemoSense system in the European Commercial Center. Researchers from Leiden University Medical Center in the Netherlands are making rapid progress on the randomized Phase 2 portion of the CHAPAN trial, with approximately 50% of the planned 76 patients enrolled. Recall the goal of this combined Phase 1B randomized Phase 2 trials is to study the safety and potential synergistic effects of systemic immunotherapy, ipilimumab, and nivolumab, or ipinivo, when combined with Delcast proprietary liver-targeted treatment in metastatic uveal melanoma patients. We look forward to the completion of enrollment into this trial, possibly as early as late next year, given the pace of recruitment, and to provide updates on the progress of the seven patients who completed the Phase 1B course of the trial. At ASCO earlier this year, the investigators reported an ORR of 85.7% and a DCR of 100%. We expect updates on the previously reported median progression-free survival of 22.4 months as the data matures. If similar results are seen in the current larger randomized phase 2 portion of the trial and the combination continues to be well tolerated, it could represent a significant improvement over current standard of care, including THP alone. While the results will be important in terms of the treatment of metastatic bubeomelanol patients, they could have relevance across multiple tumor types where hepatic metastases are present and immunotherapy is an accepted treatment. Turning to the commercial progress of Kemosat in Europe, the third quarter was the second full quarter after we resumed direct responsibility for sales, marketing, and distribution activities, which occurred on March 1st, 2022. Excluding the Netherlands, where most patients are now being treated in the Chopin trial, our units increased 41% over the same quarter last year and increased 26% versus the second quarter. We will continue to operate the business on a cash flow break-even basis for the time being, but we'll make several key hires in Germany and engage with consultants to support submissions for national coverage. These submissions are reliant on the publication of the focus trial results, which will now occur early next year. The first submission for national coverage will be in the UK. In late October, we agreed with MEAC, the previous distributor of ChemoSat in the UK and EU, on terms to settle the parties' ongoing dispute over the termination of the distribution agreement. The parties will reach a definitive settlement agreement before the end of 2022, and with this dispute behind us and the planned upcoming publication of focus trial results, we are confident that Europe will become a meaningful revenue contributor to the business, with EU revenues likely growing along with U.S. commercial launch of Hipsado, if approved next year. Also in October, we successfully completed a notified body audit to recertify our Queensberry, New York, manufacturing facility for ChemoSET under the European Medical Device Regulation, or MDR. While recertification, even under the new MDR regulation, has become routine for the company, It is important to keep in mind that our team in Queensbury has been undergoing audits for years, and I'm confident that we are well prepared for a pre-approval inspection from the FDA. Finally, we continue to lay the foundation for the planned commercialization of Hepsado. During the third quarter, we held advisory boards in the United States with interventional radiologists and anesthesiologists to gain further insight into the way treating facilities will utilize Hepsado if approved within their continuum of care. We have solidified our market access plans and are confident that for Medicare patients, that data will primarily be reimbursed using pass-through status, initially with a miscellaneous C code before being assigned our unique C code. We are carefully watching the Uniforce progress and noticed that in their first full quarter, they obtained a unique C code and booked $20 million in revenue from U.S. contract sales, despite being restricted to less than 50% of the patient population given their mechanisms of action. Based on publicly available information, the U.S. contract is priced at a level which equates to approximately $925,000 per patient based on the average duration of therapy reported for their pivotal trial. An equivalent price for the Hepsadone kit would be somewhere between $150,000 to $225,000 per kit, depending upon whether the price is based on a nine-month duration of therapy or six kits or four Hepsadone treatments over six months. the mean number of treatments from the focus row. While it is premature to finalize the price, this dynamic is important for investors to understand as we approach commercialization next year. We believe that the ultra-orphan pricing dynamic, combined with the very focused set of treating centers we will support, and the growing number of EAP sites, will translate into rapid revenue growth, a short runway to becoming cash flow positive, and very strong operating margins. Obviously, there is much to get done between now and launch, but the commercial potential for this first indication and the value it represents is clear. I look forward to taking questions, but first we'll turn the call over to Tony to review the finances. Tony?

Thank you, Gerard. Product revenues for the three months ended September 30, 2022 was approximately $906,000 compared to $395,000 for the prior year quarter from the sales of Chemostat in Europe. Our revenues increased 129% over the same period last year, primarily because we're not booking all European revenue after the termination of the MEDAC distribution agreement versus a royalty in the revenue share. Research and development expenses for the quarter increased to $4 million compared to $3 million in the prior year quarter, primarily due to higher professional service costs related to the preparation for our NDA submission by the end of this year. Dollaring general and administrative expenses for the quarter were approximately $4.5 million compared to $4 million in the prior year quarter. The increase was primarily due to recording an estimate of $1.2 million for the settlement of the MEDEC litigation, offset by lower share-based compensation expense of $800,000. Other expenses increased to $730,000 from $420,000 due to a full quarter of interest expense and amortization related to our debt financing in the third quarter of 2022. The company recorded a net loss for the three months under September 30th, 2022 of $8.5 million, $0.92 per share, basic and diluted compared to the net loss of $7.1 million, $0.94 per share, basic and diluted for the same period in 2021. On September 30th, 2022, the company had cash, cash equivalents and restricted cash totaling $14 million as compared to cash, cash equivalents and restricted cash totaling $27 million on December 31st, 2021. During the three months end of September 30th, 2022 and September 30th, 2021, we used $5.2 million and $4.9 million respectively in our cash and our operating activities. On July 20th, 2022, we closed the private placement for $5 million issuance and sale of 690,954 shares of common stock and 566,751 pre-funded warrants to purchase common stock to certain investors. Each share of common stock was sold at a price per share of $3.98, and the pre-funded warrants were sold at a price of $3.97 pre-funded warrant. The pre-funded warrants have an exercise price of a penny per share of common stock and are immediately exercisable. Delcath received quotes proceeds from the private placement of approximately $5 million before deducting offering expenses. That concludes my financial remarks. I'll ask the operator to open the phone lines for Q&A. Can you please check for questions?

Yes, sir, absolutely. We will now begin the question and answer session. To ask a question, you may press star then one on your touch-tone phone. If you're using a speaker phone, we ask that you please pick up your handset before pressing the keys. To withdraw your question, please press star then two. Today's first question comes from Marie Thibault with BTIG. Please go ahead.

Hey, good morning, everyone. This is Sam Leiber on for Marie. Thanks for taking the questions here. Maybe I can ask with my first question here, any updates or color on maybe what's happening behind the scenes here at the CROs, maybe what's left that's needed before getting this resubmission before the end of the year? Thanks.

Sure. The primary thing at this point is medical writing. We have about 98% of the data from our key CRO, a little bit more to get out of them. but really right now the gating item is medical writing, and I would say we're well down the path. It'll be towards the very end of December. If it slips, it'll slip slightly a week or so, but I'm confident we're very close to getting it filed, and I don't see any major issues in getting it done at this point.

Okay, very good. Thanks for answering that, and then maybe on the EAP sites here, I might have missed this when I prepared for March, but maybe how many treatments have been done or scheduled at this point so far, and maybe how are some of those early learnings there informing maybe the referral pathway for when you potentially do get FDA approval here?

Johnny, can you answer that in terms of how many treatments we've done to date?

Sure, Gerard. So to date, we have seven treatments. There is actually a treatment occurring today at Moffitt Cancer Center, so that would be the eighth. In terms of your question on learnings, you know, we're using the learnings from our European experience and the focus trial in the training and the conduct of the EAP. So it's still a little bit early. You know, we're carefully monitoring the safety of these patients, and we don't see any concerns with the adverse events so far that have been reported.

And, Kevin. Sorry, go ahead. Kevin, it might be worth you noting, you've noticed some interesting referral patterns going into Moffitt, I think.

Yes, we have. We've seen some patients being referred to Moffitt Cancer Center in using Hepsado as a first-line treatment, and the theory being that the theory being that destabilize the disease and preserve liver function before treatment with Chemtrak. So it's an interesting dynamic that we see here of kind of sequencing these treatments in combination to extend, better preserve the liver and deliver function in anticipation of treating with Chemtrak or Tabentapus.

And what's interesting is this concept, although obvious, is not something that we've driven at this point because obviously we're not approved. But this seems to be, it's one specific doctor, but he was a very active, I believe active in the trial. And he is now steering his, it's only, I think N equals two at this point, if I have it correct, but he's steering his HLA, the patients with the appropriate HLA phenotype to Moffitt to get treated first and then move on to ChemTrack. So as I've said before, I don't view that Chemtrak, as a competitor, I think it's a win-win for patients in that they're both out there and doctors will figure out a way to use them best in a combined fashion.

Makes sense. Thanks for taking the question.

Thank you. And our next question today comes from Scott Henry at Roth Capital. Please go ahead.

Thank you, and good morning. I guess just starting on the FDA process... First, do you think there's any risk to it being a six-month review? It would seem likely given the indication. And any thoughts on whether there'd be a panel as well as do you have any planned meetings prior to the filing? Thank you.

Yeah, in terms of risk of it being a six-month review, Review. We're trying to make sure that the package is as complete as possible. And quite frankly, we've been focused on making it very easy to navigate. You know, if you take everything given to you as some of the writers, especially the non-financial writers give it to you, it can be a barrier to navigate. So we're trying to make it, and there is a fair amount you can do, as easy as possible to navigate and review. The second thing in our favor is that it's not a particularly large filing. The drug has a long history behind it, admittedly, but it's not a very large filing, being a single trial that we're submitting. But the FDA, we all know they are overworked, and they have kicked some things down the road. So we're hopeful not, and we're doing everything we can on our end to avoid that. In terms of any meetings scheduled with them, none at this particular time. And in terms of advisory adcoms, I think it's probably as likely as not, but we will, of course, be prepping for it as if we have 100% certainty that it will happen. Obviously, there'll never be enough time to prepare if you wait for the notice.

Okay, great. And then with regards to the European revenue trends, it's certainly possible Good sequential growth from 2Q to 3Q. Should we expect continued sequential growth or will it be kind of lumpy?

Yeah, these are still fairly small numbers. So by definition, when you have small numbers, it can be very lumpy at times. Most of this revenue is coming from Germany and the UK. In the UK, we have a rep. We hired one a little bit before getting the product back. I've actually converted an MSL to a rep. And in Germany, actually, it's all referrals on their own. Basically, the product's been on autopilot for years. I think some of that growth is definitely due to our efforts. I think lumpiness is probably in order. I think what will really drive revenue in the short term is us hiring a rep in Germany to help improve referral patterns. As I mentioned a second ago, it's all kind of on autopilot. And then longer term, what will really drive revenue will be, you know, UK reimbursement will probably focus on France at some point in the next market, given the burden of disease. When the Chopin trial winds down, we'll get that back online. But, you know, I think the focus trial data is the last dynamic. When that gets published, I think that will help a tremendous amount. But as is always the case, it's a matter of getting reimbursement in each individual market. that'll take a number of years. So, you know, steady growth, but we need to get those reimbursement submissions in.

Okay, great. And final question, just with regards to the EAP site, you know, eight procedures seems like a pretty good number. I guess, how should we think about, you know, the volume per site? You know, is this like a once a week type procedure? I guess, One, I imagine it goes up, volume goes up significantly once the product's approved, but just in general, how do you think about, and obviously there are higher volume and lower volume, but on average, how do you think about volume per site as far as number of patients post-approval, you know, based on what you've learned so far? Just any color there would be helpful. Thank you.

Yeah, that's a great question, and we've been obviously focused on that ourselves, and I think it'll vary, not surprisingly, dramatically by site. I think an average of one a week per site is probably a reasonable effort after some period after launch. In terms of getting the sites to that level prior to launch via the EAP, You know, we'd have to make an effort with our MSLs, and we have one right now, to, you know, drive patients, inform clinicians about the sites and the referral patterns in a compliant manner, of course. You know, could we get it up to one a week prior to that? That probably would be a reach given our current resources. But I think, you know, the demand is certainly there if we're able to communicate it. But again, we're being very careful as to how hard we hit the accelerator. I think I've said this before. just trying to harbinger our resources at the moment. But I think post-launch, I think one a week is feasible, and I think we probably could get up to maybe as high as 20 sites over time within perhaps two years post-launch. But we're hopeful that we'll have seven sites up and running at launch and probably well under one a week at that point, but moving towards that.

Okay, great. That's helpful. Thank you for taking the questions.

Thank you. And our next question today comes from Yale Jen with LeBron Company. Please go ahead.

Good morning, and thanks for taking the questions. Do I remember that there is a focus study in terms of the final survival data? That potentially could be available, I believe, by May of next year. If that's the case, would you need to further submit that data to the agency for the approval, or that's not relevant for that process?

The primary endpoint of the trial is objective response rate, so there won't be any need to update the data. The data we're submitting to the FDA is a slight update since the last update we've given publicly. And in regular filings, if there's an abstract or something that we publish with a further update, that would go into the FDA so they would be informed, but it wouldn't be a significant update. So short answer is no. It's not necessary. It's not part of the process, but they will be kept informed.

Okay, great. That's very helpful. Just two more quick ones. First, housekeeping questions that... Based on the expenses, operating expenses, should we anticipate that going down further sequentially compared to third quarter or the fourth quarter? Or how should we think about that?

I think you just assume they're about on a steady state for the next two quarters.

Okay, great. And maybe the last question here is that Once the FDA accepts the application, I assume a month after it was submitted, could you tell us the procedure or the process in terms of the FDA facility inspection and possible timeline of that? So that's probably the last piece for the agency in the process to complete their work.

Yeah, there's no formal, you know, cut and dried, it's always X, but I would expect, you know, four to six weeks prior to the purgatory date, then scheduling a pre-approval inspection.

Okay, great. Okay, great. That's very helpful, and congrats on all the progress, and look forward to you guys filing the things before the end of the year. Thanks, Gil.

Thank you. And our next question today comes from Bill Markham with Canaccord Genuity. Please go ahead.

Good morning, and thanks for taking the question. So after a recent FDA advisory committee for another oncology product in a small orphan population, there's a little bit more of a renewed focus on what the FDA is expecting to prove efficacy in a single-arm trial in a small population. So I was just hoping you could kind of I hit the highlights again. I know you've gone through it before, but in terms of what the FDA expected or required of your pivotal data, specifically as you can, what they needed to see to prove efficacy and to the extent that you were able to compare that to results outside of your trial, the suitability of that comparison and you know, how satisfied the FDA will be that Hepsado is achieving the level of response needed for approval?

Sure. Well, I think the first thing, you know, is a single-arm trial. And what the FDA stated to us when we were discussing with them turning this into a single-arm trial is they wanted to see a, you know, clinically meaningful objective response, right, that had a clinically meaningful duration of response. Picking up that second one, duration and response, because that's the simplest, they asked us to do a follow-up for at least six months to demonstrate that the duration of the response was meaningful. And what we actually had was a 14-month duration, and that is, frankly, hitting the ball out of the park in terms of durations. So we know we're on very, very solid ground there. In terms of objective response rate, that's a little harder to point to something specific the FDA has said to us. Now, we did tell them that we were powering the trial to show a meaningful improvement based on a meta-analysis of immuno-oncology agents, and we had our lower bound needed to be 8.3% on that. Our lower bound was 26.4%, so obviously we were well over that hurdle. Now, the FDA might decide that that in itself is inadequate, and we, of course, will, in terms of of evidence in terms of a comparison. So we have other things we can pull upon, which are some are quite obvious. I think the most compelling one is to look at, you know, OS. Our OS is fairly similar to what Debentapa showed. And we had sicker patients in terms of we had first, second, third line patients. You know, we have a variety of parameters that we can compare it to and will based on their published data that demonstrates that our patients were were further along in the disease process, yet we came within spitting distance of their overall OS. And then if we look at a one-year OS, they were, I believe, 77%. We were at 77%, excuse me, surviving for a year. They were at 73%. So we have a number of things we can point to. If we look at more older survival data, pre-Chemtrax and Ventipus publication, We're well, well over, you know, usually it's not over, it's well under a year in terms of survival. So, you know, that's well in our favor as well. So I think, you know, with our overall OS, you know, we said 19 and a quarter last time we gave an update, but, you know, that was versus the DAC, that little stuff compares to our, we have a 14 and a half months. You know, we have that Delta, that OS continues to mature, so that's definitely not the final number. And it compares reasonably favorably with ChemTrack, We have the meta-analysis in terms of ORR, objective response rate. And our response rates are head and shoulders above anything else out there. Most response rates are single-digit. And then the duration, 14 months. So taken in totality, I think we're in great shape. I think the last thing I would mention is, although we haven't published this, I have stated qualitatively our response rates, our category of response rates, whether or not you are Complete responder, a partial response for progressive disease, that all correlates with survival quite cleanly. So therefore, we can show that the response rate, the ORR, is meaningful in terms of relapse, which is always the case for all classes of therapy. So that's an important component as well. So I've thrown a lot at you, but I think we have a lot at our disposal. So I just wanted to make sure I was complete with that.

Absolutely. I appreciate the thorough answer. Thank you.

Thank you. And ladies and gentlemen, this concludes our question and answer session and today's conference call. We thank you all for attending today's presentation. You may now disconnect your lines and have a wonderful day.
