Great. Thank you, Ali, and good morning, everyone. This morning, Dr. Kellum and I are here to provide an update on the Tigris trial, specifically enrollment activity, key Tigris clinical and regulatory milestone timelines, and the company balance sheet. After our prepared remarks, we will open the floor to a Q&A session. As we close out 2024, we are currently at 138 patients enrolled. This caps a very robust year of enrollment into Tigris and puts us within striking distance of our full enrollment milestone. As we ended the Q3 of 2024, we were ahead of our projected timeline and believed that we would hit the full enrollment mark sometime around the end of 2024. Subsequently, in October, we experienced a slowdown in enrollment.
This slowdown was due to issues within the medical supply chain caused by Hurricane Helene, specifically a U.S.-wide saline shortage, which impaired enrollment activities since early October, and they do persist today. That being said, our understanding is that production and allocation issues should be resolved by end of 2024 or early January 2025. As such, we expect TIGRIS enrollment to revert to the normalized levels experienced throughout the first half of 2024 and do project full enrollment by the end of Q1 2025. I'll now hand the call over to Dr. Kellum, who will provide an update and some more color around the TIGRIS trial and these timelines.
Thanks, Chris. I guess we'll start with screening and enrollment. I think it's important to acknowledge that our screening activity actually has remained very strong. We've missed some enrollments, as Chris mentioned about the saline shortage, and I'll talk more about that in a minute. I have to say that sites remain very excited about applying this technology. We've had no sites withdraw from the trial despite its vintage. I would say that the PIs are eager to finish the trial and have continued access to this technology in its commercialization phase. However, the saline shortage has been an issue, and it has impacted enrollment over the last couple of months. As you know, Hurricane Helene hit in the end of September, and it disrupted supply chain of fluids, particularly saline, and that's had an impact on our trial.
Each of our PMX devices requires five liters of saline flush prior to use. This is to remove residual fluid in the material related to storage. Since each patient requires at least two cartridges, we're talking about 10 or even 15 liters of saline, which is quite a lot. To allocate that has been a challenge for certain sites, in fact, for most sites, in the middle of this shortage. Although other fluids could be used, the manufacturer's specifications really say only saline. Because the product's still investigational, we're really bound to these specifications. Site PIs are understandably frustrated about this, as are we. The shortage issue has been an ongoing problem. However, I do think that we're starting to see a light at the end of the tunnel. The December numbers are improving. We've had about a one-a-week enrollment in December.
We're optimistic that this is now easing. Another update concerns our target enrollment, which has always been 150 evaluable patients. What this effectively means is that we have to enroll 100 patients in the PMX arm and 50 patients in the standard of care arm who actually receive the assigned treatment. For standard of care, this is obviously pretty easy, although it's theoretically possible to fail here with, for example, a withdrawal within the first 24 hours of randomization. For PMX, it's much easier to run into staffing or logistic issues around the product and between randomization and treatment.
Therefore, we have, over the course of the trial, experienced a few patients, six in total, that have not received the intervention and therefore need to be effectively replaced. We will enroll another six patients, therefore, in the PMX arm, and given the randomization schema, this means that we'll have to be enrolling somewhere around 7- 10 patients in addition to the bare minimum of 150. This is important for our safety analysis and some of our secondary analyses. What does this mean for the overall timeline between the saline delay and the additional patients? Assuming that the saline shortage issue will be resolved, we do still expect full enrollment by the end of the Q1 of 2025, which will mean that top-line release of data will occur approximately 120 days from the last patient enrolled, so call it early Q3.
The FDA submission will occur somewhere around the end of Q3 with trial publication sometime shortly thereafter, and a complete FDA review expected by first quarter of 2026. With all of that, I'll turn things back over to Chris.
Thanks, John. Before we wrap up and move on to the Q&A session, I'd like to address Spectral's balance sheet liquidity. With existing cash on the balance sheet, we have cash runway to complete enrollment of Tigris, as we've stated previously in prior corporate updates. We will look to execute a financing to fund our regulatory phase. To that end, we have had discussions with several of our key stakeholders, and we will look to find constructive pools of capital as we've done on the last three funding rounds. We feel very good about our prospects to fund Spectral, and attract the right pools of capital as we enter the home stretch of this trial and enter into the regulatory submission phase. With that, I'll hand the call back over to Ali. Darrell, if you could open the call to questions and field questions, please.
Thank you. We'll now be conducting a question and answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment please while we poll for your questions. Our first questions come from the line of Scott McAuley with Paradigm Capital. Please proceed with your questions.
Morning, everyone. Thanks for taking the questions and thanks for the update. Obviously, the IV fluid shortage issue has been frustrating, I can imagine. I don't know if you have a sense, maybe Dr. Kellum, of how many, we're at 138 now, the potential impact of the IV fluid shortage. How many patients could have been recruited if it wasn't for that shortage at the moment, if you have an idea?
Well, Scott, thanks for the question. I think if you look at where we've been sort of running, even if you take a more conservative estimate of the average enrollment of six or seven patients a month, there's really no particular reason why October and November, even with the Thanksgiving holiday down here in the U.S. We historically had a strong November in the past. My guess is we would have had six or seven patients enrolled each month. What does that mean? That means that we're probably down, call it a dozen patients and would have been at or around 150 now if it wasn't for the saline shortage.
Yeah. You highlighted that the screening rates remain robust, which is fantastic to hear. Is it essentially the sites that have been strong throughout the trial, they continue to remain strong? Are you seeing some of the sites that maybe had been underperforming starting to pick up now that we're seeing the light at the end of the tunnel in terms of enrollment and them wanting to get in another patient or two if they had been underperforming during the year? Talk a little bit about those kind of underlying screening dynamics.
I would say that the pattern of screening and the pattern of enrollment has largely been the same through the course of the trial. We have had some ups and downs with certain sites that were strong initially and then maybe faltered a little bit, and then some of those sites have picked up a little bit in recent months. It's hard to say. Obviously, there are external factors. We do have a PI going on maternity leave now, and I would expect that that site won't be enrolling. We have other sites that have had external factors which have impacted the availability of staff, et cetera, staff turnovers, all those sorts of variables, which over the course of the trial do impact enrollment. I would say overall, the high-performing sites remain high-performing and the not as high-performing sites are pretty much exactly where they've been.
I don't see much of a change there, and frankly, I don't really anticipate very much. This is sort of trial maintenance 101 in the sense that a majority of patients are actually enrolled by, call it 25% of the sites.
Yeah, definitely. On the number of patients, good to get some info out there on the need for more than the 150. Is there any update on the PrisMax sub-study? Kind of enrollment on that, how that's going? Do you think this is going to impact whatever the final number is? If it's 155, 160, what have you?
Yeah. No, we've enrolled 12 patients into the sub-study, so we're really in good shape in terms of getting to at least 15 patients enrolled. I think we're pretty much I won't say we're in the clear with regard to that trial yet, but I think it's looking pretty good that we should be able to achieve complete enrollment in the sub-study. I think we had some concern previously that we might run out of patients before we got that study fully enrolled, but I don't think that's much of a concern anymore.
That's great to hear. I know in the past, the EDEN sub-study had been something that kind of interested in and highlighting. Is there any expected updates on that in the coming months?
Yeah. We're obviously focused primarily on getting the Tigris trial completed, but the EDEN data are locked, clean, and are undergoing sort of, I guess, primary analysis is completed. We've actually got some abstracts that'll be presented at the upcoming Society of Critical Care Medicine meeting in February. We anticipate having the manuscript submitted for publication prior to that and I would say the target of January at this point to wrap that process up.
That's great. Lastly, I'm sure there's other questions in the queue. Maybe just switching over to Vantive. I know I think we're expecting that Carlyle potential acquisition to close in the coming month or two. Has that impacted the interactions that you guys have been having with the kind of colleagues over at Vantive? Have you noticed any shifts? Is there any tangible movement on reimbursement or marketing or any of the other kind of pre-launch activities that you guys have been working on that you can kind of point to or talk to?
Well, I'll let Chris comment on this as well. I would say from the clinical perspective, it really has been full speed ahead with that relationship. I haven't seen any change at all. It's been strong and aggressive, and I think we're on track on all the fronts that you've mentioned. I would anticipate that that will continue as it has. I don't know if, Chris, you have any more specific details you want to offer.
Yeah. Thanks, John. Scott, I would just characterize the relationship as progressively stronger every week. The activity that's being undertaken by Vantive is an incredible workload, especially on the marketing side and as they look forward to uptake, how they market this, how they brand this. There's a ton of field work going on, including the addition of incremental Vantive bodies now, if you will, towards this project. I don't think that, once again, and I'll reiterate this, I don't think we could have asked for a better partner. In fact, I feel that this Vantive carve-out has been quite good. At least I'm speaking for Spectral. I think this has been quite good for the prospects of PMX, and the focus on PMX as a strategic priority for Vantive.
That's great to hear. Thanks, everyone. I'll hop back in the queue.
Thank you. Our next question has come from the line of Kevin Veenstra with Private Investor. Please proceed with your questions.
Yeah. Thanks for the information update. Can you hear me okay?
Yes.
Yeah. Thanks, Kevin.
Great. Super okay. Just a few questions. My first question was around the saline solution. I do appreciate the fact that is a difficult situation. I am just wondering, is there any opportunity just to ensure things do finish up on the revised time schedule to purchase saline and dedicate it to the sites that are higher enrollment, so that we are not waiting or maybe back of the line for other uses of saline within a given hospital?
I'll address that. Kevin, it's not really possible. It's a nationwide shortage, we can't dedicate volume specifically for the trial. Unfortunately, despite the fact that this is an intervention that's designed to improve survival, it's still considered to be a research application as opposed to someone who needs surgery, for example. We're always going to be a bit behind the eight ball with respect to that. However, Baxter's actually been very helpful to us in terms of helping to get solutions moved around, helping to free up solutions that, for example, expired lots and things like that that have been set aside for purposes of use in the priming as opposed to other uses and have offered other solutions that different sites are applying.
I think people are doing what they can do, and I think there's really not an opportunity to specifically buy solutions in the setting of a nationwide shortage. I do think everything that can be done is being done, and I do have a good sense now that things are starting to ease. We really have seen an increase in enrollment. Although I'm still hearing from the sites that they're, on a case-by-case basis, having difficulty. It does seem like it's starting to subside, and I do think, certainly by the end of this month, we hopefully start the first of the year back on the usual timetable.
Kevin, just to add to that. My understanding is that production issues have been resolved or will be resolved by the end of this month. I think there's a much clearer view on that. Allocation issues will take at least a couple of weeks to work through. There's the production side and allocation. Production certainly sounds like it's been solved, and it's just allocation just takes one to two weeks following the resolution of the production issues to work through the system.
Okay. That's fair. Next question is around the two-one randomization. Is that done, or was that done at the start of the study? What I'm trying to get at here, I guess is it two-one randomization at each trial site, or is it overall kind of top going down, and so every time a new patient gets enrolled, it's really counting down from 150 down to 0. I don't know if that makes sense. I'm just trying to get a sense if it's two-one at the trial site level or at the overall kind of trial level.
Yeah. It's a block randomization, each of the sites are at a two-one randomization. Yeah, it's at the site level.
If you have some sites that are very, very low, you may have to wait to get that third-
No, we don't have a specific number. Yeah, I misunderstood your question, I guess. We just have to get to 100 evaluable patients. It doesn't have to be any kind of equal distribution across sites or anything like that.
Oh, okay. Got you. Then with respect to the 50 standard of care, were you able to fill those, I guess, faster because even though there's a saline solution, you don't really need saline for the standard of care?
No, unfortunately, because you have to be able to know that we have what's called allocation concealment, where we don't know what the patient's going to be randomized to until they're randomized. If they were to randomize a patient and not have saline and need it, then that would be another patient randomized and not treated, which is obviously a problem. No, they can't randomize unless they know they can proceed with the treatment if they're randomized to the treatment arm.
Okay. Got you. Just one last question. In terms of cash, this is probably a question for Chris. How much cash do you think you need to the end in terms of additional raising or capital raise?
Yeah. Kevin, I think we've addressed this in the past. In terms of the funds on hand, today, we have enough to finish full enrollment, and I think we've been resolute on that. Now, listen, we had a little bit more room when we executed the financings last year. Certainly, we've been backed up a couple months from our projected timeline. That being said, we did have buffer. In terms of to get to FDA approval, we've talked about anywhere from a number of, call it, CAD 10 million-12 million to get to FDA approval from thereon.
Okay. That's great. Thank you.
Thank you. There are no further questions at this time. With that does conclude today's conference call. We do appreciate your participation. You may disconnect your lines at this time. Enjoy the rest of your day.
