To Rick Pauls, DiaMedica's President and Chief Executive Officer. Mr. Pauls, you may begin, sir.

Speaker 1

Thank you, Paul. Hello, everyone, and welcome to our Q2 conference call. I'm joined this morning by Scott Kellen, our Chief Financial Officer. Before we begin this morning, I want to take a moment to welcome Doctor. Richard Koontz to our Board of Directors.

Speaker 1

Doctor. Koontz recently retired from Medtronic, where he was the Chief Medical Officer, Chief Scientific Officer and a member of the Executive Committee. Prior to that, he served as a Senior Vice President and President of Neuromodulation of Medtronic. Before Medtronic, he was the Founder and Chief Scientific Officer of the Harvard Clinical Research Institute in Boston. He also served as an associate professor of medicine at Harvard Medical School, Chief of the Division of Clinical Biometrics And as an interventional cardiologist in the division of cardiovascular diseases at the Brigham and Women's Hospital in Boston.

Speaker 1

He also served as an advisor to multiple national and regional committees in the National Academy of Medicine and National Institutes of Health. Doctor. Koontz has directed numerous multicenter clinical trials and has authored over 200 original publications. We are grateful to have Rick join our Board. His experience complements and broadens the knowledge and skill set of our Board.

Speaker 1

Turning back to our update. The Q2 saw 2 important milestones for DiaMedica and our shareholders. The FDA's lifting of the clinical hold on our REMEDY 2 stroke trial and the completion of an at the market financing raising gross proceeds of $37,500,000 Starting with the FDA, on June 21, we announced that the FDA had fully lifted the clinical hold on our REMEDY-two Phase twothree clinical trial Studying DM199 as a treatment for acute ischemic stroke or AIS. With this decision, we immediately reengaged with our study support vendors I've selected a new contract research organization with strong current experience in the stroke space. As many As you know, there is a great deal of work involved with preparing for a pivotal registrational clinical trial.

Speaker 1

I can assure everyone that our entire team is excited and focused on working with our CRO, the supporting vendors and key advisors for the resumption of the trial. Recall that we have a bit of a leg up as we have approximately a dozen sites already under contract from last year. Additionally, we are now also evaluating the addition of clinical sites outside of the U. S. To increase our enrollment rate in countries viewed as being able to enroll more quickly than their U.

Speaker 1

S. Counterparts. Our goal is to deliver a complete and clean clinical data package to the FDA at the conclusion of the REMEDY-two trial, Enabling the FDA to accept and improve DM199. It has been with this objective in mind that we expanded our clinical team over the past year. As of today, all key vendors have been engaged and are actively pursuing preparations for the resumption of patient enrollment.

Speaker 1

The estimated time line has not yet been finalized, but based upon discussions with RCO and multiple others, we are optimistic That enrollment for the interim analysis can be completed before the end of 2024. The final timing will come down to the actual pace of enrollment. I want to stress With our recent capital raise, which brought in significantly more capital than anticipated, we are able to pursue expanding the study globally In order to increase the enrollment rate with the intent to ultimately reach both the interim and final analysis more quickly, we expect to be able to provide more clarity On the overall timeline at our Q3 earnings call, on a related note and as we've previously discussed, We are conducting a Phase 1c open label single ascending IV dose study of DM199 In healthy volunteers, using the same PVC IV bags as in the REMEDY-two trial, the first part of the study demonstrated the safety of our planned 0.5 microgram per kg IV dose level to be used going forward in the REMEDY-two trial. It also demonstrated that this dose level achieved our Targeted KLK1 blood concentration level, a level that we believe is the desired therapeutic range similar to our prior Phase 2 STOKE trial and the reported drug levels of the human urine derived KLK1 protein widely used in China under the product name KalaKang.

Speaker 1

We were able to report today that we also completed a 4th cohort in the Phase 1c study consisting of 3 Hypertensive patients on ACE inhibitors. These patients received the 0.5 microgram per kg dose Using the updated methods planned for the REMEDY-two trial, we are pleased to see that all participants received the full IV dose and there were no instances of hypotension or large drops in blood pressure. We believe that the additional clinical data from these combined results will provide further assurance To current and potential physician investigators that the correct IV dose level has been identified and patients including ACE patients Maybe safely enrolled in the REMEDY-two trial. Turning to our second milestone, we also significantly strengthened our balance sheet during the past quarter. In June, we completed an offering of straight common shares, no warrant coverage priced at the market.

Speaker 1

Gross proceeds from the offering were $37,500,000 And net proceeds were $36,100,000 bringing our cash balance to over $60,000,000 at the end of the quarter. The financing was led by existing investors who contributed A significant portion of this capital raise and who remain enthusiastic about DM199 and its potential to offer a compelling new treatment option for stroke patients. We also had excellent participation from our management team and board Who collectively invested $700,000 We are grateful to our investors who have put us in a position where we believe we can now drive our destiny. We believe that we now have the sufficient capital enabling us to complete the interim analysis with the remaining cash runway of approximately 1 year. We focus on the interim analysis.

Speaker 1

It has the potential to signal a beneficial impact of DM199 to stroke patients. A patient set that has not seen a significant therapeutic development in over 25 years since the approval of tPA. Before I turn the call over to Scott, I also want to call your attention to a new video and slide in our corporate deck that had created, which further illustrates the DM199 mechanism of action as it applies to stroke patients. Specifically, DM199's role in increasing collateral circulation. The key updated mechanism message In response to ischemic conditions caused by a stroke, the bradykinem 2 receptors expressed on endothelial cells in the arteries of the brain are highly upregulated locally in the ischemic penumbra.

Speaker 1

This increase maybe by as much as 40 fold higher based upon testing in animal models. By augmenting with DM199, we believe a significantly greater number of the upregulated bradykin 2 receptors Maybe activated causing the beneficial focal vasodilation in the affected area of the brain, the ischemic penumbra, to increase blood flow and oxygen. We believe this improved collateral circulation will salvage brain tissue and penumbra and lead to improve patient outcomes. This video can be found on our website at www.diamedica.com and scrolling down to the front page to the section titled Advancing Patient Care with Innovative Treatments. I would like to now turn the call to Scott Kellen to review the financial highlights.

Speaker 2

Thanks, Rick, and good morning, everyone. As Rick mentioned, we strengthened our balance sheet considerably in June with the completion of a $37,500,000 private placement with accredited investors. Net proceeds from the transaction were approximately $36,100,000 and also when David Wombeck joined us as our Chief Business Officer in April. He invested $750,000 As a result, Our June 30, 2023 total cash, cash equivalents and marketable securities increased to $60,600,000 up from $33,500,000 at the end of 2022. Our cash usage was $10,100,000 for the 6 months ended June 30, 2023 compared to $6,400,000 in the prior year period.

Speaker 2

The increase in our cash usage was due primarily to a combination of factors, including the completion of the end use and the Phase 1c studies, Ongoing manufacturing development work, our expanded management and clinical team to support the REMEDY-two trial and our lawsuit with PRA. We believe that our current capital will support the clinical development of DM199 and our operations into 2026. Our research and development expenses increased to $2,500,000 for the 3 months ended June 30, 2023, up from $2,000,000 in the prior year period. R and D expenses increased to $6,200,000 For the 6 months ended June 30, 2023 compared to $3,900,000 for the 6 months ended June 30, 2022, The increase for the 6 month comparison was due primarily to costs incurred for the INU study performed to address the recently lifted clinical hold On our REMEDY-two trial and costs incurred for the Phase 1c study determining the DM199 blood concentration levels achieved with the new IV dose of DM199. Also contributing to the increase were increased manufacturing and process development costs, Costs incurred to finalize the clinical data and perform the related analyses for the REDOX trial and increased personnel costs associated with These increases were partially offset by decreased costs incurred for the REMEDY-two trial, which until late June had been on clinical hold.

Speaker 2

Our general and administrative expenses were $2,200,000 For the 3 months ended June 30, 2023, up from $1,400,000 for the 3 months ended June 30, 2022, G and A expenses were $4,100,000 for the 6 months ended June 30, 2023, and this was up from $3,000,000 for the 6 months ended June 30, 2022. The increase for the 6 month comparison was primarily due to increased legal fees Incurred in connection with our lawsuit against PRA Netherlands and increased personnel costs associated with expanding our management team. Increased professional service fees and non cash share based compensation also contributed to this increase. Now before I turn you back over to Rick, let me also provide a brief update on our ongoing lawsuit against PRA Netherlands. As many of you will recall, in December of 2022, the Netherlands court at our request Seized our study records from PRA.

Speaker 2

Then in April 2023, following a March 2023 hearing, The Netherland Court issued a ruling affirming our ownership of the study data and importantly stating that PRA had no legal basis for withholding the study data. PRA appealed this decision in June. And while this appeal may take 9 to 12 months to resolve, It is not holding up our main damages lawsuit. This hearing is currently scheduled for December 7 this year And we look forward to presenting our case against PRA and providing our analysis of the damages caused by PRA's actions. It's also interesting to note that the same 3 judge panel that oversaw the hearing on our ownership of the study data is scheduled to oversee the hearing for the main lawsuit.

Speaker 2

For more information regarding the background to this lawsuit, please see our SEC filings. Now let me turn the call back over to Rick.

Speaker 1

Thanks, Scott. With that, we would like to open the call for questions. Paul, if you could please open the line for questions.

Speaker 3

And our first question comes from Thomas Flaten from Lake Street Capital.

Speaker 2

Your line is open.

Speaker 4

Hey, good morning.

Speaker 5

Thank you. Good morning, guys. Appreciate taking the questions. Hey, Rick, with respect to The patients that were enrolled in the study prior to the clinical hold, I don't know if you've told us how many there were, but will they be Kept in the efficacy analysis set or will they be censored out?

Speaker 1

Yes, Thomas. So we haven't disclosed that number, But we do plan to have those included in the analysis.

Speaker 5

Got it. And then for the interim analysis, Given the change to the endpoint, is the number of patients still the same for the interim analysis?

Speaker 1

Yes, we're still planning for 144 patients for the interim analysis.

Speaker 5

Got it. Got it. And then you're still shooting for

Speaker 4

a total of 75 sites, is that right?

Speaker 1

So the current plan It's currently being revised kind of live as we move ahead. Currently, we're working towards 40 sites in the U. S, 10 sites in Australia. And then as I mentioned on the prepared remarks, with the additional capital that came in, we're also looking at going Further ex U. S, we're looking at Canada and Europe.

Speaker 1

There's some work right now just making seeing what it's going to take in terms of timelines to add. But I think it's important for us if we can expand internationally to increase the enrollment rate for the trial.

Speaker 4

Excellent. Appreciate you taking the questions. Thank you.

Speaker 6

Thanks, Thomas.

Speaker 3

And our next question comes from Alex Nowak of Craig Hallum Capital Group. Your line is open. All right. And Mr. Nowak, your line is open.

Speaker 4

Okay. Hopefully, you can hear me this time. I'm not sure what you could hear, what you couldn't hear, Rick. But just with regards to they getting compared to when REVENUE II was initially started, it sounds like maybe some more international exposure was a new requirement, but anything in addition?

Speaker 1

Yes. So Alex, so that we're in a different environment today. So we're a year plus now past COVID. So it was important for us to take the learnings we had previously. And then we were looking for a global CRO that could Really help us with expanding outside of the U.

Speaker 1

S. As well, but also importantly having a CRO that could that has recent Experience with stroke trials. So that was an important piece. So the CRO we've selected has extensive experience with a number of more recent trials, Better understanding, I'd say of a good understanding of sites that could ideally be strong enrollers for this trial.

Speaker 4

Okay, understood. And then maybe expand on the expected international uptake of DM199 in the clinical study versus domestic uptake. Why would international necessarily go faster? Just from your conversations, what are you thinking there?

Speaker 1

Yes. So as we we're looking at enrollment rates of past trials. What we did see in particular in Europe that the enrollment rates Per site per month was a fair bit higher than what we're than what's been seeing for U. S. Trials.

Speaker 1

And part of that may be associated with socialized healthcare. But based upon this, we think it'd be it's important If we seriously can look at ex U. S. Expansion.

Speaker 4

Okay, understood. And then do you need a specific number of patients In the U. S. Versus OUS to meet that statistical analysis plan or is that kind of getting baked in with the 40 sites U. S.

Speaker 4

And then a remainder amount OUS?

Speaker 1

There's not. The context here also is the timelines to get sites set up in Europe will be longer than they are in the U. S. So in particular for the interim analysis, we still think it's going to be driven by the U. S.

Speaker 1

Sites and then the other Ex U. S. Sites will be supplementary.

Speaker 4

Okay, understood. And then just a 2 part question to end it out here is, at first, I think the REMEDY 2 patients With ACE inhibitors would have been excluded, but will this be reversed based on the Phase 1c's findings in that 4th Cohort. And then the second part of the question is any other protocol changes to be aware of?

Speaker 1

Yes. So, if a Patient was previously on an ACE inhibitor. There will be a 24 hour washout so that the drug will effectively be out of the system. And this is something actually is quite similar with the human urinary form of the protein in China. There's also a 24 hour washout.

Speaker 1

So all the patients will be included in the study. And just for context again in our Phase II trial for stroke, We had about 10 patients that were previously on ACE inhibitor. Of the 46 total patients on drug, there were no instances of hypotensive events. And then we made a couple of other protocol changes, learnings, I call it from the hold. In particular, we're going to be starting off with a 15 minute slow infusion.

Speaker 1

And so if there are signs of large drops in blood pressure, And the dosing will be over 3 hours instead of the prescribed 1 hour. And so we think the hypotensive events really is a result of overwhelming the system very rapidly When the dosing first starts. So that's going to be an important aspect of it. We ran the Phase 1c trial and in particular the ACE Cohort, that we just recently completed. I think just to giving us and also importantly to give the clinical side some comfort here That we feel that we've addressed the dosing and matching the dosing to what we had previously had in our Phase II trial, Which was comparable to the drug exposure level with the human urinary form of the protein in China today.

Speaker 4

Okay, makes sense. Well, appreciate the update and congrats on getting

Speaker 3

And our next question comes from Francois Brisebois from Oppenheimer. Your line is open.

Speaker 6

Hi, this is Dan on for Frank. Thanks for taking my questions. In relation to the interim analysis, is the plan still to end the study if you see great efficacy In around the 140 patients, any changes there?

Speaker 1

Yes. So similar to what we've discussed in the past. So at the interim analysis, there's really 3 scenarios. So the first is that we'll stop the study for futility. So if we're not seeing a positive drug effect, We'll stop the study for overwhelming efficacy and that's based upon hitting a P value of less than approximately 0.0072 Or alternatively, we will continue this study and we'll do a resampling size where the total size will be somewhere between 240 and728.

Speaker 6

Great. Thanks. That makes sense. And just a quick one. Regarding the Phase 1c data in hypertensive Had any of the dozen sites from before requested to see additional data in patients or This is more of a proactive mode as you target new sites.

Speaker 1

Yes, this was completely proactive. First off, the FDA did not ask us to run this trial. So we did that proactively. And then none of the sites had asked. When we talk to sites and we're talking about the hypotensive events, This is something that's manageable.

Speaker 1

By stopping the infusion, the blood pressure in the 3 patients that we had that were these 3 serious adverse events, The blood pressure returned back to normal within minutes, but this was just another basically in the proactive way of providing additional comfort In case in the future any new sites that we talk to have any concerns about large drops in blood pressure. And keeping in context here is that these neurologists, Many of them every day are dealing with treating patients with tPA and realizing that 5% to 6% of patients on tPA, it causes a severe brain hemorrhage. So we think that the drop in blood pressure is manageable, but we just want to make sure we're comfortable and also for the sites as well with the dosing.

Speaker 6

Thanks for taking my questions.

Speaker 1

Thank you, Dan.

Speaker 3

And seeing no further questions in queue, I'll turn the call back over to our host for closing comments.

Speaker 1

All right. Again, we'd like to thank everyone for joining us this morning and for your continued support. Our goal is to bring this important treatment to stroke patients as quickly as We appreciate your interest in DiaMedica and your continued support. With that, this concludes our call today. Thank you.
