With that said, I would now like to turn the call over to Dr. Milton Werner. Milton, you may begin.

Milton Werner: Thank you, Alex, and thank you, everybody, for joining the call today. Before I begin, I just want to give a round of applause to our outgoing Chief Financial Officer, Joe Frattaroli, who is on the call. Tomorrow will be his last day with the company and we are very grateful for the six years of work that he and I have done together to bring Inhibikase where we are. Also to introduce you to our new Chief Financial Officer, who will begin on Monday, formally in the job, Garth Lees-Rolfe, who will be discussing our financial results. And so with that, I really appreciate everybody joining the call for our discussion of our fourth quarter and full year 2023 financial results and recent clinical and business updates.

2023 was really a year of execution as we made significant advancements across our clinical pipeline, culminating in our recent pre-NDA meeting with the FDA for IkT-001Pro and the rapid enrollment of Parkinson's patients in our 201 Trial for Risvodetinib or Risvo as we'll refer to it throughout this presentation. We are also evaluating new second-generation molecules arising from our internal medicinal chemistry and external collaborations that could further expand our pipeline and enhance suppression of neurodegeneration or address other diseases that can be benefiting from Abel-kinase inhibition. While we have much work to do in 2024, we believe that we are well positioned for success and continue to build value for our shareholders. Let's now take a deeper dive into each of our programs, starting with Risvodetinib or Risvo.

As you may remember, Risvo is a potent selective inhibitor of c-Abl that is administered once daily and that we believe may slow or halt progression of Parkinson's disease. Our 201 Trial is a two phase trial with an ongoing 12-week double-blinded study across three doses that we believe should be therapeutic, plus a fourth group that is taking a placebo. The trial is approximately 61% enrolled as of March 22, with 73 participants, 20 prospective participants in medical screening and an additional 48 potential participants being evaluated for suitability to initiate medical screening. Additionally, 34 participants have completed the full 12-week dosing period. To date, 15 mild and two moderate adverse events have been observed that may be related to Risvo treatment.

Two people elected to withdraw from the trial despite having only one or two moderate adverse events. We believe the last patient will be enrolled during the summer of 2024. To date, trial recruitment has been successful in our review, generating broad interest within the Parkinson patient community nationwide, allowing for hundreds of unique individuals to be screened by an outside medical staff and referred into our clinical sites prior to entering a medical record review process in advance of an initiation of formal medical screening. We plan to report top line results from this study in the second half of this year. The 201 Trial plans to enroll everyone who continues to meet the eligibility criteria into a 12-month extension study. Although we have completed several of the infrastructure builds to execute this trial, we are still in need of additional financing to begin enrolling participants into the extension study at our clinical sites.

As we have previously disclosed, the extension study will transition participants from the blinded phase who will still meet the enrollment criteria to an additional 12-month of treatment which will also serve the purpose of evaluating our novel commercial tablet formulation for Risvo that we announced last year. As we continue to establish the potential of Risvo in Parkinson's disease, we believe it is important to communicate the progress to key stakeholders in the medical and scientific community. In January, we published the Phase I/Ib data evaluating Risvo in healthy volunteers and the patients treated with anti-Parkinson's medications. That report appear in the peer-reviewed Journal, Journal of Parkinson Disease. The publication highlighted the safety, the tolerability and pharmacokinetics of Risvo across 94 healthy volunteers and 14 participants with Parkinson disease in both single, ascending dose and multiple setting dose studies.

We found that Risvo demonstrated a favorable safety and tolerability profile for all trial participants with 12 potentially treatment related adverse events observed, none of clinical significance. Single dose pharmacokinetics were approximately anywhere between 12.5 and 200 milligrams for both Cmax and the area under the curve or AUC measurement with no pharmacokinetic difference between healthy voluntaries and participants with Parkinson's disease. Exposures of these dose were high, relative to other drug in the same class, same kinase inhibitor class. And of note, we used voluntary lumbar puncture to measure the concentration of Risvo in cerebral spinal fluid in six participants with or without PD, which indicated that Risvo crossed the blood-brain barrier and was persistently present in the central nervous system.

While this is a limited data set, we find these results encouraging. And we're all, we believe that the totality of the data we've generated to date continues to support the development of Risvo and we look forward to providing updates on the progress of the 201 Trial throughout the year. Moving now to IkT-001Pro, which is a prodrug formulation of imatinib mesylate that has been designed to improve on the safety profile of imatinib, we had a pre-NDA meeting on January 19 of this year with the FDA to discuss the requirements for potential approval of IkT-001Pro under the 505(b)(2) statute. We're pleased with the discussion we had with the agency as we begin the process of building our first NDA package, and we plan to seek all 11 blood and stomach cancer indications for which imatinib mesylate has been approved.

The FDA review team from the Division of Hematologic Malignancies determined through a review of our clinical data that 600 milligram and 800 milligram IkT-001Pro provided similar exposures to 400 milligram and 600 milligram imatinib mesylate, respectively. The review team advised that if we want to seek all the indications for which imatinib has previously been approved, we should measure the safety tolerability pharmacokinetics of IkT-001Pro that would deliver up to 800 milligrams, the highest approved dose of the imatinib mesylate. We plan to evaluate IkT-001Pro at a 1200-milligram dose, which we believe will lead to exposures to imatinib that are similar to 800 milligrams of imatinib mesylate. Further review team asked that we evaluate whether 001Pro and imatinib are absorbed differently from the gut.

So we are initiating a standard preclinical test to further evaluate IkT-001Pro and imatinib gut absorption, which is a test performed in cell culture. As we continue to advance the elements of the NDA package, we will seek milestone meetings with the FDA to ensure we are meeting manufacturing, scientific and quality control requirements for approval. Now before I turn the call over to our incoming Chief Financial Officer, Garth Lees-Rolfe, to review our financial results for the quarter, I'd like to again extend our deepest gratitude from both the Board of Directors and our entire team to Joe Frattaroli for his years of service as Chief Financial Officer, and we all wish him best in his retirement. With that said, I'll turn the call over to Garth to review our financial results.

Garth Lees-Rolfe: Thank you, Milton. Now let me review our financial results for the year and quarter ended December 31, 2023. Net loss for year ended December 31, 2023, was $19.0 million or $3.57 per share, compared to a net loss of $18.1 million, or $4.28 per share for the year ended December 31, 2022. Research and development expenses for the full year ended December 31, 2023 was $13.6 million compared to $12.0 million for the full year 2022. The increase was primarily due to a $1.5 million increase for IkT-001Pro and a decrease of $0.6 million in expenses for Risvo and a net increase of $0.7 million for all other R&D activities. Selling, general and administrative expenses for the full year 2023 was $6.7 million compared to $6.2 million for the same period in 2022.

The $0.5 million increase was primarily the result of an increase in investor relation costs of $1.0 million, an increase in employee costs of $0.3 million that were partly offset by decrease in D&O insurance of $0.6 million, a decrease in legal and consulting fees of $0.4 million and a net increase of $0.2 million in all other selling, general and administrative expenses. As of December 31, 2023, we had $13.3 million in cash, cash equivalents and marketable securities. We expect that existing cash and cash equivalents will be sufficient to fund operations into the first quarter of 2025. That concludes review of our financial statements. I'd like to hand the call back over to Milton for closing remarks.

Milton Werner: Thank you, Garth. As we look ahead to 2024, we will continue to take advantage of the recent momentum we have experienced to continue to create value for our shareholders. We believe that the recent feedback from our pre-NDA meeting was constructive as we plan to conduct additional tests and studies to begin to build our first NDA submission package. In addition, we will continue to enroll patients into our 201 Trial and expect to provide top line data from this study in the second half of the year. Our recent publication of early clinical data for Risvo in the Journal of Parkinson Disease reinforces our belief that Risvo could be a transformative treatment for patients with Parkinson disease and related disorders.

We look forward to continuing to establish ourselves as a leader in the development of treatments for neurodegenerative disease. And we want to thank all our shareholders and trial participants for their continued support since we advance the medicines for patients with high unmet medical needs. I would now like to open the call for questions. Operator?

Operator: Thank you. We will now be conducting question-and-answer session. [Operator Instructions] Thank you. And our first question is from the line of Ed White with H.C. Wainwright. Please proceed with your questions.
