Thank you, John, and good afternoon, everyone. It gives me great pleasure today to host this, our first quarterly conference call as Lasada Therapeutics, where we will provide an overview of recent business highlights and discuss our third quarter 2022 financial results. At Lasada, we strive to create value for our shareholders and for our stakeholders, the patients who suffer from the debilitating and often grave diseases that we have targeted and the physicians who treat them by developing and commercializing products that address important unmet medical needs. Our portfolio of product candidates contains treatments in development that are designed to be regenerative and or to bring significant therapeutic improvement. As a development company, our focus is on the generation of meaningful data by the most expeditious and cost-effective means as evidenced by the fact that even though our merger with SEND Therapeutics occurred approximately six weeks ago, we are in a position today to report tangible progress advancing LSTA-1, or Lista-1 as we call it internally, the company's lead investigational product candidate from our proprietary Sendar platform. Lista-1 is the subject of multiple planned and ongoing clinical trials being conducted globally in a variety of solid tumor types and in combination with several chemotherapy and immunotherapy anti-cancer regimens. Based on favorable safety, tolerability, and activity data to date, we believe Lister 1 has the potential to become an integral part of a revised standard of care therapy for many difficult-to-treat cancers. In the past few weeks, we have received advice from the U.S. Food and Drug Administration on what would be required of us for registration. We have discussed this guidance with our development partners, and we are now preparing for the implementation of protocol changes that we expect will improve the regulatory standing and scientific value of our studies. Our Chief Medical Officer, Dr. Buck, will provide more specifics on our clinical program shortly following our review of the quarter's financial results. However, before getting into that, allow me to introduce LASADA's President and Chief Business Officer, David Slack. David is a seasoned industry executive with over 25 years of experience in public and private life science companies, working in a variety of senior business roles. We believe that his experience and expertise will prove instrumental to Lazada as we work to expand the applicability of ListaOne and the Sendar platform programs to other solid tumor targets, treatment combinations, and corporate partnerships. With that, I'll turn the call over to David. Oh, and by the way, In order to avoid confusion internally, we've adopted the convention of referring to David as David and to me as Dave. David?

Thanks, Dave. It's great to be a part of today's call. It was a real pleasure working with the teams at Send and Colladrius during the merger, and now to be a part of the combined team at Losada. What excited us at Send the most about this merger was the expertise and experience of the team that was already in place at Caladrius, stewarded by Dave Masso's leadership, and the shared enthusiasm and focus to advance and develop ListaOne and to broaden the applications of the SendR platform. We believe that Lasada has the potential to revolutionize the treatment of cancer, and I'm pleased to be a part of such a talented, and dedicated team with a goal to not only create value for shareholders, but most importantly, to bring innovative treatments to patients in need. And with that, I now will turn over the call to James Nisko, our VP of Finance and Treasury, to review and provide commentary on our third quarter 2022 financial results. James?

Thanks, David. Good afternoon, all. I'm pleased to join you today to present a summary of our third quarter 2022 financial results, starting with operating expenses. Research and development expenses were approximately 3.4 million for the three months ended September 30th, 2022, compared to 4.1 million for the three months ended September 30th, 2021. representing a decrease of 0.7 million or 18.1%. This was primarily due to a decrease in expenses associated with our Exona Phase 2B study, the Freedom Trial, as a result of the suspension and enrollment in the second quarter of 2022 and study closeout activities in the third quarter of 2022. a decrease in expenses associated with Honedra in Japan related to study closeout costs, partially offset by the addition of chemistry, manufacturing and controls, also known as CMC, activities for LISTA-1, and enrollment activities for Australasian Gastrointestinal Trials Group, also known as AGITG, a SEND study. research and development in both periods related to expenses associated with our Exona Phase 2b study, the Freedom Trial, expenses associated with our registration eligible study for Honedra in critical limb ischemia in Japan, as well as corresponding regulatory discussions and support expenses. expenses associated with the preparation of our filing of an investigational new drug application, as well as study execution expenses for the clinical study of Lista 201 for treatment of diabetic kidney disease, a Phase 1B open-label proof-of-concept trial, which includes six subjects in total. and expenses associated with the addition of CMC activities for LISTA-1, enrollment activities for the LISTA-1 Phase 2b ASCEND study, and preparatory activities associated with the design of a planned LISTA-1 proof-of-concept basket trial in various solid tumors and in combination with the corresponding standards of care. General and administrative expenses, which focus on general corporate-related activities, were $3.9 million for the three months ended September 30, 2022, compared to $2.8 million for the three months ended September 30, 2021, representing an increase of 39%. This increase was primarily due to an increase in equity expense as a result of performance stock unit vesting, one-time merger option assumption expense, and departing board member restricted stock unit vesting, in addition to an increase in expenses associated with our annual stockholder meeting and merger. Net losses were $37.4 million for the three months ended September 30, 2022, compared to $6.9 million for the three months ended September 30, 2021. Turning now to our balance sheet and cash flow. As of September 30, 2022, the company had cash, cash equivalents, and marketable securities of approximately $75.5 million. That completes the financial overview. I will now turn the call over to our Chief Medical Officer, Dr. Kristen Buck, for the review of our clinical development pipeline. Kristen?

Thank you, James, and good afternoon, everyone. I will begin by providing a high-level summary of what we are doing at La Sada and why we believe our development programs are an increasingly relevant and attractive investment opportunity today. Before that, though, I'd like to reiterate our motivation to translate our expertise and unique scientific approach into clinical trials, which could lead to treatments for patients most in need. Lissata's pipeline is built on a portfolio of proprietary and patented technology that is grounded in strong scientific rationale to identify and treat patients most likely to respond to our targeted therapies. We appreciate the critical importance of generating meaningful clinical data to validate our platform technologies and create shareholder value, and our entire team is focused on accomplishing this quickly, cost-effectively, yet rigorously. With that, I will now provide a summary and status update for each of Lasada's clinical development programs. kicking off with our lead product candidate, ListaOne, for the treatment of advanced solid tumors in combination with other anti-cancer agents. Despite advances in cancer therapy today, many solid tumors remain difficult to treat. Many solid tumors, including pancreatic cancer, gastric cancer, and other solid tumors are surrounded by dense fibrotic tissue known as stroma that limits the efficacy of current chemotherapies for the treatment of a variety of advanced solid tumors. Many tumors also exhibit an immunosuppressive tumor microenvironment, or TME, which suppresses a patient's immune system's ability to fight the cancer and therefore can limit effectiveness of current therapies. These factors negatively impact the ability of many cytotoxic agents and immunotherapies, to effectively treat these cancers. To address the tumor stroma's role as a primary impediment to effective treatment, Lissata's approach is to activate the CN rule, or SEND-R, natural transport system that normally brings nutrients into a tissue under emergency situations such as an injury. Tumors hijack this system to promote their growth. Lasada's lead candidate, Lista-1, formerly known as Send-1, is an investigational drug that actuates the Send-R active transport mechanism while also having the potential to modify the tumor microenvironment and make it less immunosuppressive. Lista-1 targets the tumor vasculature by its affinity for alpha-V, beta-3, and beta-5 integrins that are selectively expressed in tumor vasculature but not healthy tissue. Lista-1 is a specific cyclic internalizing RGD peptide that, once bound to these integrins, is cleaved by proteases expressed in tumors to release a peptide fragment called a SendR fragment, which then binds to a second receptor called Neuropilin-1 to activate a novel uptake pathway that allows anti-cancer drugs to more selectively penetrate solid tumors. The ability of ListaOne to modify the tumor microenvironment to enhance delivery and efficacy of co-administered drugs has been demonstrated in a range of preclinical solid tumor models. These results come internally from Lissata and from collaborators and research groups around the world. and have been the subject of over 200 scientific publications. Along with our collaborators, we have amassed significant non-clinical data demonstrating enhanced delivery of a range of emerging anti-cancer therapies, including immunotherapies and RNA-based therapeutics. Clinically, LISTA-1 has demonstrated favorable safety tolerability, and activity in clinical trials to enhance delivery of standard of care chemotherapy for pancreatic cancer. We are exploring the potential of LISTA-1 to enable a variety of treatment modalities to treat a range of solid tumors more effectively. Currently, LISTA-1 is the subject of a Phase 1b-2a and 2b clinical studies being conducted globally and various solid tumors. These include metastatic, pancreatic, ductal adenocarcinoma, colorectal cancer, and appendiceal cancers in combination with a variety of anti-cancer regimens. Additionally, the evaluation of LISTA-1 administered in combination with corresponding standards of care in advanced solid tumors and a phase two placebo-controlled basket trial is planned to initiate in the first half of 2023. As Dave Mazzo mentioned earlier, the FDA provided us with guidance on the requirements for a pathway to registration in the US for Lista 1 in metastatic pancreatic ductal adenocarcinoma, or as we refer to it as MPDAC. We have subsequently shared this feedback with our global partners, and are now finalizing development programs and individual study protocol modification to address FDA's recommendation. Turning now to LSTA-12, or Honedra in Japan, our product candidate for the treatment of critical limb disease, excuse me, critical limb ischemia, or CLI, and Berger's disease. Hanedra was awarded a Sakagaki designation from the Japanese regulatory authorities for the treatment of CLI and Berger's disease, which is an orphaned size subset of CLI. The Sakagaki designation is akin to a Regenerative Medicine Advanced Therapy designation or an RMAT designation in the United States. Sakagaki designation affords the recipient prioritized regulatory consultation a dedicated review system to support the development and review process including the option of a rolling registration submission as well as a reduced review time of six months for the registration application once filed additionally under japan's regenerative medicine legislation products such as hanedra are eligible for early conditional approval and possibly full approval in japan based on the assessment of the data from the trial or trials designed in direct collaboration with the Japanese Pharmaceuticals and Medical Devices Agency, or PMDA. Note that conditional approval of a regenerative medicine product only requires the demonstration of a trend toward therapeutic effect, together with acceptable safety. Further, the Sakagaki designation is a highly sought regulatory classification in Japan, and we hope that this, coupled with positively trending data from our trial, will make Henadra an attractive product for partnering to a Japanese pharmaceutical company. Data from the follow-up of all patients treated in the company's registration-eligible study of Henadra in Japan for the treatment of CLI and Berger's disease are consistent with our expectations of therapeutic effect and safety based on previously published clinical trials data generated in Japan and the United States. These data have been compiled and are the subject of discussions with the PMDA as part of the Japanese regulatory pre-consultation process and in preparation for the formal consultation meetings which precede the Japanese new drug application. If successful in the pre-consultation process, Lasada expects formal clinical consultation to occur by mid-year 2023. Concomitantly, the company continues its efforts to secure a Japanese partner to complete the remaining steps to produce registration in Japan. Moving on to Exona, or LSTA-16, for the treatment of coronary microvascular dysfunction, or CMD. Coronary microvascular dysfunction is a disease that continues to be underdiagnosed and potentially afflicts millions annually, a vast majority of whom are female, with no current treatment options. In May of 2020, Caladrius announced the full data results from the Phase 2a ESCAPE-CMD trial, showing a highly statistically significant improvement in coronary flow reserve correlating with symptom relief for patients with CMD after a single intracoronary injection of Exona. Subsequently, the company initiated a rigorous phase two clinical trial known as the Freedom Trial, which to our knowledge is the first controlled regenerative medicine trial in CMD in the United States. The FREEDOM trial was a double-blind, randomized, placebo-controlled trial designed to corroborate the results of the ESCAPE-CMD trial while assessing the efficacy and safety of delivering autologous CD34 cells, our Exona product, to subjects with CMD and without obstructive coronary artery disease. Unfortunately, and as previously reported, the COVID-19 pandemic in the United States had both a direct and indirect impact on freedom, which made enrollment much slower than originally predicted and challenging to accelerate. As a result, the company suspended trial enrollment and conducted an interim analysis of the data. Following this analysis and along with key opinion leaders' input, the company determined that execution of a redesigned freedom-like trial would be the appropriate next step, but the cost of such a trial would be prohibitively expensive to undergo without a strategic partner. Thus, Exona development will only be continued if a strategic partner that can contribute the necessary capital for future development is identified and secured. Lastly, LSTA-201 for the treatment of diabetic kidney disease, or DKD. The company initiated a Phase 1B open-label proof-of-concept trial evaluating LSTA-201, a CD34-positive regenerative cell therapy investigational product for intrarenal artery administration in patients with diabetic kidney disease. This development program focuses on patients that exhibit rapidly progressing stage 3B or 4 disease. The scientific rationale for the program is based on the association of progressive kidney disease with attrition of the microcirculation of the kidney. Preclinical studies in kidney disease and injury models have demonstrated that protection or replenishment of the microcirculation results in improved kidney function. Our proof-of-concept protocol provided for a staggered, sequentially-dosed cohort of six patients overseen by an independent data safety monitoring board with the objective of determining the tolerance of intrarenal cell therapy injection in diabetic kidney disease patients, as well as the ability of LSTA-201 to regenerate kidney function. A key readout of data will occur at the six-month follow-up visit for all patients. The first patient was treated in the study of LSTA-201 in April 2022, followed by completion of enrollment of all six subjects in July 2022. We continue to anticipate top-line data from all subjects by the first quarter of 2023. With that, I will now turn the call back to Dave.

Thanks, Kristen. As you've heard, our talented and dedicated team is working hard to maximize the value potential of our development pipeline and to drive our programs to clinical success. We have designed our studies to provide clear results as fast and inexpensively as reasonably practicable. Nevertheless, we understand and even share your impatience in getting the quality data and ask for your indulgence and understanding as we focus on achieving this goal. We are excited by the promise of our platform technologies and pipeline of product and partnering opportunities and look forward to providing updates on our progress in the coming months. And with that overview operator, we are now ready to take questions.

As a reminder, to ask a question, please press star one one on your telephone. You will then hear an automated message advising that your hand is raised. Each listener will be permitted to ask one question at a time and will return to the queue for additional questions. Please stand by while we compile the Q&A roster. Our first question comes from Pete Enderlin with MAZ Partners. Your line is now open.

Thank you. Hi, everybody. Hey, Pete. Dave, this is kind of a broad question, but I'll categorize it as one question, and that is, you know, you're going to engage in potentially a very large number of trials and development activities with major pharmas in many cases. So can you talk around the framework of how you're going to structure those, generally speaking, I mean, in terms of cost sharing and protecting respective IP rights and resolving potential conflicts between different partners and between the partners and your company itself? Just a lot of sort of general possible variability in the way all those agreements will work, but maybe there's some common ground underneath them all.

Sure, Pete, and thanks for the question. Actually, there's quite a bit of common ground in our strategy, although you're right, different agreements with different companies will have different terms. But generally speaking, our goal is to find mechanisms by which we can broadly explore the potential for Lister 1 to augment or enhance the activity of a variety of combination of cytotoxic and immunotherapies. So without the one big pharma agreement that has been announced already is that with Roche Genentech, and we're not going to be able to give all the specifics in public, but generally speaking, this is a shared program. So we are testing ListaOne in combination with Standard of Care and MPDAC, along with Roche's immunotherapy, atezolizumab. And the general structure of this deal is that each company owns their own IP, that if there's any new IP generated during the course of the work, and one would expect that that would not occur, but if there was, we would share it, and that the costs of the trial are generally being split equally. Each company provides their own drug for the trial use, and we've each put in a certain amount of money. Roche, however, is actually executing the trial as part of their Morpheus platform. So they have probably dedicated more resources to the program than we have in our entire company, in fact. But it's basically a shared arrangement. Now, going forward, similar arrangements will be looked to be established with other companies, the idea being that ListaOne has a promiscuous mechanism of action, meaning that it is agnostic to the chemo or immunotherapies with which it is administered, and we believe its mechanism of action has the ability to enhance the delivery of all of these things to the targeted areas of solid tumors. And so we expect that we'll be in a position to have a variety of deals where we always either share the cost or have the partner bear the cost and where we retain complete product rights to list to one. And so that's the general approach.

Well, just a quick follow-up to that. And that is if, for example, Roche does a lot of their own work and actually

implementing the trial would they allocate any of that back to you or would that just be on their their dime so to speak no no the the the resource distribution and cost distribution is is defined in the the contract and there's no way that either party is going to be able to you know back charge the other surprise charges it's just okay not possible thanks a lot thank you pete

We stand by for our next question. Our next question comes from Shabhandu Roy with Brooklyn Capital Markets. Your line is now open.

Hi, thanks for the update. With regards to the phase two basket trial for LISTA-1 next year, what kind of tumors are you planning to include there? Would you also, are you thinking of evaluating brain cancers as well, where at least one is required to cross the blood-brain barrier?

So I'll let Kristen, our chief medical officer, jump in here and give you the latest on our plans for tumor types in the basket trial, as well as some other arrangements that we're making to look at different tumor types, including potentially glioblastoma. Kristen?

Hi, great. Thanks for the question. The basket trial is looking at head and neck squamous cell carcinoma, esophageal squamous cell carcinoma, and cholangiocarcinoma. The first two being second-line therapy, the latter being first-line therapy. As Dave alluded, we're also looking for explorations in joint development in tumors such as first-line glioblastoma. potential collaborations in locally advanced pancreatic ductal adenocarcinoma, and potentially locally advanced resectable gastroesophageal adenocarcinoma. So we are truly looking across solid tumor types as we believe this asset is tumor tissue agnostic. Dave?

Thanks. Thanks. Great. Thanks for the call.

You're welcome. Thank you for joining.

As a reminder, to ask a question, please press star 11 on your telephone. At this time, I am showing no further questions. My apologies. Please stand by for our next question. Our next question comes from Pete Enderlein with MAC Partners. Your line is now open.

Oh, thanks. I just remembered that I had a question about stock options at send before the deal closed. Were there any? Because I thought there was a provision for them, but then I think I read that there actually was none that actually transferred over. So what's the story about that?

James, would you like to take that? Sure. Describe briefly the treatment of the stock options. Yes.

Hi, Pete. Through the merger, the company acquired about 1.3 million shares, stock options from SEND. So we assumed them over and converted them at the same exchange ratio that we did for any shares that we acquired through the merger.

Okay. Thanks. You're welcome.

Thank you.

This concludes the question and answer session. I will now turn the call back to Dr. Mazzo for closing remarks.

Well, again, thank you all for participating on today's call. We look forward to speaking with you again during our next quarterly conference call and to continuing to provide updates on our achievements and progress. We remain grateful for your continued interest and support. Stay well and have a good evening.

This concludes today's conference call thank you for participating you may now disconnect.
