Brian
Thank you. And thank you, everyone, for joining us today for our second quarter 2024 business update. We are pleased to report on our progress with the precision medicine strategy for fadracycline, or FADRA, our oral CDK2-9 inhibitor, which was highlighted at the ASCO annual meeting in June. Recruitment in the enriched cohort of our R65-101 phase two proof of concept study is going well. In this cohort, we're evaluating FADRA as monotherapy in patients with CDKN2A and or CDKN2B chromosomal abnormalities, including deep deletions or loss of function. The hypothesis we are testing prospectively builds on the clinical evidence and the Phase I clinical data presented at ASCO, which evaluated FADVAS monotherapy from an unselected population. Clinical benefit was observed in heavily pretreated patients with several tumor types, including endometrial, lung, ovarian, pancreatic cancer, and T-cell lymphoma. Retrospective analysis suggests that this activity may be associated in part with alterations in certain tumor suppressor genes, specifically CDKN2A and or CDKN2B. We believe that there is great unmet medical need and industry interest in the patient population identified by CDKN2A or B abnormalities. which are closely located on chromosome 9 and are often co-deleted. CDKN2A gene deletions occur in several solid tumors, including bladder, breast, endometrial, esophageal, glioma, head and neck, hepatobiliary, lung, including squamous, melanoma, ovarian, pancreatic, and also in certain T-cell lymphomas. PPTN to B deletions occur in several solid tumors, including bladder, breast, cholangiocarcinoma, endometrial, esophageal, glioma, head and neck, hepatobiliary, lung, including squamous and mesothelioma, melanoma, pancreatic, and others. Based on currently available data, we believe that FADRA has a strong competitive profile in its therapeutic class. We expect to report on initial clinical activity from the Phase II proof-of-concept part of the study starting in the fourth quarter of this year. I will now turn the call over to Brian to review our progress and discuss some of our clinical results in the FADLA program. Brian?
Brian
Thank you, Spiro. As Vera mentioned, we are recruiting well in the FADRA POC study, and I'm very encouraged by the enthusiasm of our clinical investigators about enrollment of patients with CDKN2A-B cohort. Based on the pace of enrollment, we anticipate reporting initial results from around a dozen patients by the end of 2024. We have also opened a second cohort, which is recruiting patients with T-cell lymphoma. This was based on phase one signals of activity, including partial responses in two out of the three patients with T-cell lymphoma. As we progress with the phase two study, let me summarize the data presented at ASCO and the rationale for our clinical strategy. The ASCO dataset included 47 patients from the phase one dose escalation path of the CYC065101 study, evaluating different FADRA dosing schedules as monotherapy in unselected population. Patients were heavily pretreated, having received a median of four prior lines of therapy. Charka was generally well tolerated with good compliance between dose level one and five. Dose level five, or 100 milligrams twice daily, five days a week, four out of four weeks, was selected for the phase two proof of concept part of the study. There were no drug-related SAEs at this dose level. The most commonly reported treatment-related adverse events were nausea, vomiting, diarrhea, fatigue, and hypoglycemia. A total of 25 drug-related SAEs were reported in eight patients. Most common were hypoglycemia in four patients, platelet count decrease in three, and accidental overdose in three. A total of 34 patients had measurable target lesions at baseline. Two partial responses were reported in patients with T-cell lymphoma, one of whom had a CDK2N2A loss. A squamous non-small cell lung cancer patient with CDKN2A and CDKN2B loss achieved a 22% reduction in tumor burden at four weeks. In addition, clinical benefit was reported in two patients with endometrial cancer, one each with ovarian and pancreatic cancer. A retrospective analysis of previously treated Phase I patients identified an endometrial cancer patient who achieved a complete response over three years of treatment in a previous intravenous FADRA monotherapy study and was found to have a CDKN2A, CDKN2B, and NTAP loss. Although the phase one hypothesis generating data are limited, and cannot be generalized, we believe that the data supports evaluating the two patient cohorts with specific cancer types in the phase two POC part of the study. We look forward to reporting initial data in the upcoming months. I will now turn the call over to Paul to review the second quarter results. Paul Farmer Thank you, Brian. As of June 30, 2024, cash equivalents totaled $6 million compared to $3.4 million as of December 31, 2023.

R&D expenses relating to FADRA were $1.5 million for the three months ended June 30, 2024, as compared to $3 million for the same period in 2023, due to the decrease in clinical trial and other non-clinical expenditures. R&D expenses raised duplexoxetib, our PLK1 inhibitor, were $0.5 million for the three months ended June 30, 2024, as compared to $1.4 million for the same period in 2023, due to a decrease in manufacturing costs and other nonclinical expenditures. General and administrative expenses remain flat at approximately $1.6 million for each of the three months ended June 30, 2024 and 2023. Total other expenses in net were $0.1 million for each of the three months ended June 30, 2024 and 2023.

Thank you, Mr. McBaron. Ladies and gentlemen, at this time, if you would like to ask a question, please press star 1 on your telephone keypad, and you may remove yourself from the queue at any time by pressing star 2. Once again, that's star 1 for questions today. We'll go first to Ahu Demir at Ladenburg-Holmen.
Ahu Demir
Good afternoon. Thank you very much for taking my questions. We have a couple. First question is, what is the enrollment target for the CDKN2A and 2B program? And other part of the question is, What would be the, what are the scenarios for this program and what would be the benchmark and success that you would consider based on the data that you plan to disclose in the second half of this year?
Brian
Thank you for your question. I think this is for Brian.
Brian
Go on over to you. Hi. I'll say, so the first question, is it's a sort of a two-stage process. The stage one is to look at approximately 12 to 14 patients where you need to see more than two responses. And then you would move on to the next phase of the study. So success for the first part would be at least two resist responses in the first 12 to 14 patients. I hope that Terrified in the next phase will be able to confirm that those responses just confirmed in a bigger cohort.
Ahu Demir
Yes, that's helpful, Brian. And from how many patients are you planning to show data in the second half of this year, and what is the target enrollment for this program?
Brian
Accrual has been good, and the patients required, you know, that we need have been screened. So we anticipate that's why we're reasonably confident we'll be able to, you know, present at least just around a dozen patients' worth of response data by the end of the year. Just to remind everyone, we scan here every two months. So, you know, if we're already in August, it would be sort of two months for the first scan and two months for the second scan to get the efficacy data on that group.
Ahu Demir
If I could ask one more question, Brian, I think I would refer that question to you as well. In terms of the alterations, Is there any reason to think the loss of CDK and 2A and 2B would be more potent form instead of the mutations and other alterations? Or it could be any of these and with the data disclosure in the second half would we be able to see what is the status of these different alterations?
Brian
you bring up a really interesting point in terms of you know, the different, either deletions or different mutations that are present. I think from what we've seen so far is we'll be able to get at least a feel from, you know, our old treated patients custom new set, which would be way over 20, 25 patients to see is there a specific alteration that's more sensitive to the drug. So we'll get an idea. There are numerous different ones, and hopefully from that analysis, we'll be able to hone it down even a little bit more.
Ahu Demir
Great. Thank you so much for answering my question.
Operator
Thank you. And just a quick reminder, ladies and gentlemen, star one, please, for any further questions today. And gentlemen, it appears we have no further questions this afternoon. Mr. Rambadis, I'll turn things back to you, sir, for any closing comments.
Brian
Thank you, Bo, and thanks to all of you for joining SACLS Health second quarter 2024 earnings call. We have achieved key milestones for FADRA with multiple patients dosed in the phase two proof of concept stage and look forward to important catalysts in 2024. These include reporting interim data from initial cohorts in the Phase II open-label concept stage of the O65-11 study with oral FADRA in patients with advanced solid tumors and lymphoma. We look forward to providing you with further updates and hope to meet some of you at upcoming conferences. Operator, at this time, you may end the call.
Operator
Thank you, Mr. Rambadis. Again, ladies and gentlemen, that will conclude Cyclist Sales Financial Results Conference Call. Again, thanks so much for joining us, everyone, and we wish you all a great remainder of your day. Goodbye.
