Good afternoon, and welcome to the Cyclacel Pharmaceuticals First Quarter 2024 Results Conference Call and Webcast. [Operator Instructions] Please note, today's call is being recorded. I would now like to turn the conference call over to the company. Please go ahead. .
Good afternoon, everyone, and thank you for joining today's conference call to discuss Cyclacel's financial results and business highlights for the first quarter ending March 31, 2024.
Before turning the call over to management, I would like to remind everyone that during this conference call, forward-looking statements made by management are intended to fall within the safe harbor provision of the Private Securities Litigation Reform Act of 1995 and Section 21E of the Securities Exchange Act of 1934 as amended. .
As set forth in our press release, forward-looking statements involve risks and uncertainties that may affect the company's business and prospects, including those discussed in our filings with the Securities and Exchange Commission, which include, among other things, our Forms 10-Q and 10-K. .

With us today are Spiro Rombotis, President and Chief Executive Officer; Paul McBarron, Executive Vice President, Finance and Chief Operating Officer; and Dr.
Brian Schwartz, Chief Medical Officer. Spiro will begin with an overview of our business strategy and progress. Brian will provide details on Cyclacel's clinical program, and then Paul will provide financial highlights for the first quarter of 2024, which will be followed by a Q&A session. .
At this time, I would like to turn the call over to Spiro. .
Thank you, Grace, and thank you, everyone, for joining us today for our first quarter 2024 business update. As previously reported, we have closed the financing for $8 million in gross proceeds in a private placement priced at the market per NASDAQ rules.
With additional resources in place, we have begun dosing patients in the Phase II proof-of-concept part of our 065-101 study, evaluating fadraciclib of fadra for short in patients with 1 or more chromosomal abnormalities, including CDKN2A and/or CDKN2B deep deletions or loss of function..
You will recall that we are pursuing a potential precision medicine approach for fadra, an oral CDK2/9 inhibitor following findings in our clinical and preclinical data, which suggests the hypothesis that patients with one or more of these chromosomal abnormalities maybe sensitive to fadra.
In the Phase II part, we are evaluating patients selected for their mutational profile and/or Phase I activity in various solid tumors and lymphoma.
We're initially enrolling 2 patient cohorts, those with CDKN2A and/or CDKN2B abnormalities and also T-cell lymphoma based on observation of anticancer activity, including responses in multiple Phase I patients. .
We believe that there is great unmet medical need and industry interest in the cancer patient populations identified by these 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. .
CDKN2B 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. There are no approved drugs to treat patients with CDKN2A or B abnormalities.
We expect 2 key data readouts for fadra this year. Final data from the dose escalation part of the 065-101 study to be presented at the ASCO 2024 Annual Meeting in a few weeks and support on initial clinical activity from the Phase II proof-of-concept part of the study in the second half 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 fadra study.
Brian?.
Thank you, Spiro. In our recently completed 065-101 study, we determined the recommended Phase II dose for fadra. As a reminder, this is 100 milligrams BID dosed orally, 5 days per week in a 4-week cycle. No dose-limiting toxicities were observed on the schedule.
We have now dosed the first patient in the Phase II proof-of-concept part of the study with the initial focus of the cohort in patients with CDKN2A or CDKN2B alterations. In order to speed up enrollment, we have opened additional sites with up to 7 participating in the Phase II. We expect to deliver initial results by the second half of 2024. .
As we progress through the Phase II study, let me summarize the rationale for our clinical strategy. We have observed CDKN2A or CDKN2B alterations, including loss of function in multiple, pretreated Phase I patients with various cancers.
These included gynecological, hepatobiliary, lung, pancreatic and recently testicular who benefited from fadraciclib monotherapy. These patient groups are associated with a high unmet need and often have poor clinical outcomes. .
As an illustration, we were excited to see shrinkage of 22% in the sum of all target lesions after 1 cycle of oral fadra monotherapy in a squamous non-small cell lung cancer patients with CDKN2B deletions refractory to standard-of-care chemo and immunotherapy.
A recently enrolled patient with advanced testicular cancer patients post surgery achieved a 12% reduction in the sum of all target lesions in the first cycle and continues on therapy now as Cycle 3.
After retrospectively analyzing a subset of previously treated Phase I patients, we found a total of 8 patients with CDKN2A or CDKN2B alterations, all of whom experienced clinical benefit of the fadra monotherapy.
These included an endometrial cancer patient who achieved a CR and over 3 years of treatment on the previous IV fadra monotherapy study and was found to have CDKN2A and CDKN2B loss.
We are also encouraged by our Phase I anticancer activity observed in T-cell lymphoma patients, including PRs in 2 out of 3 patients treated, one of whom who had loss of CDKN2A. .
Literature suggests that a large percentage of T-cell lymphoma patients have loss of CDKN2A. Although the Phase 1 hypothesis generating data are limited and cannot be generalized, we believe that the data supports evaluating patients with these cancer types in Phase II proof-of-concept part of the study.
I will now turn the call over to Paul to review our first quarter results. .
Thank you, Brian. As of March 31, 2024, pro forma cash and cash equivalents totaled $9.9 million, which includes proceeds from this month's private placement and $0.8 million cash received for the second and final part of the United Kingdom research and development tax credit claim for 2023. .
Cash and cash equivalents as of March 31, 2024, totaled $2.8 million compared to $3.4 million as of December 31, 2023.
Net cash used in operating activities was $0.5 million for the 3 months ended March 31, 2024, which includes $2.9 million received in March in respect to the first part of the 2023 R&D tax credit claim compared to $6.9 million for the same period of 2023. .
Research and development or R&D expenses were $2.8 million for the 3 months ended March 31, 2024, as compared to $5.7 million for the same period in 2023.
R&D expenses relating to fadra were $1.8 million for the 3 months ended March 31, 2024, as compared to $4.1 million for the same period in 2023 due to a decrease in clinical trial and other nonclinical expenditures.
R&D expenses related to plogo were $1 million for the 3 months ended March 31, 2024, as compared to $1.4 million for the same period in 2023 due to a decrease in manufacturing and other nonclinical expenditures. .
Expenses related to plogo will be greatly reduced in 2024 as we have paused the 140-101 study while a new salt formulation becomes available. General and administrative expenses remained relatively flat at approximately $1.6 million for each of the 3 months ended March 31, 2024, and 2023. .
Total other expenses, net for the 3 months ended March 31, 2024, were $0.1 million compared to $0.2 million for the same period of the previous year.
United Kingdom research and development tax credits for the 3 months ended March 31, 2024, were $1.4 million, which includes $0.8 million related to the 2023 claim which, as I mentioned previously, we have now received payment, compared to $1.3 million for the same period of the previous year and are directly correlated to qualifying research and development expenditure.
.
Net loss for the 3 months ended March 31, 2024, were $2.9 million, which includes stock-based compensation expense of $0.2 million compared to $5.8 million, including stock-based compensation expense of $0.4 million for the same period in 2023. .
As we concentrate our resources on recruiting patients in the specific cohorts in the fadra Phase II study, we anticipate that our expenditures in 2024 will continue to decrease. The company estimates that its current cash resources will fund currently planned programs into the fourth quarter of 2024. .
Operator, we are now ready to take questions. .
[Operator Instructions] Our first question comes from Ahu Demir with Ladenburg Thalmann. .
Two from us.
First one is what are we expecting to see at ASCO from the fadraciclib 101 study? Could you provide more color? How many patients are we going to see subset analysis and any additional information would be very helpful?.
Thank you for your question, Ahu. I will turn over to Brian to answer the question on the ASCO content. .
Ahu, we're basically planning to present almost the totality of the dose escalation portion of the study. The data cut was a couple of weeks ago, but we should have full data set around the Phase I dose escalation portion, including both the safety and efficacy seen so far. There'll also be PK and PD included. .
Another question I have is on the proof-of-concept Phase II portion of the same study. We are expecting to see data later this year.
Curious, what is the time line? When are you going to present? And currently, how many sites are open? And what are your thoughts on the enrollment? How fast that might move forward?.
Brian?.
We've just opened the T-cell lymphoma site. We're starting to open slightly different from the Phase I solid tumor sites. The solid tumor sites, we had already 4 sites enrolling. So it's just opening an additional 3. In terms of timing, these known mutations are sometimes difficult to determine the frequency.
But we're quite encouraged at the moment of patients being identified. We anticipate most probably by the end of the year, we've enrolled both cohorts. .
Let me also add to Brian's color, Ahu, that these mutations are readily available as part of standard panels.
We do not need a companion diagnostic to identify the patients, although the company is collecting data for future regulatory discussions, but the important points that they are amply available and there is no approved drug to treat these patients once they're identified with the abnormality. .
We have no further questions in the queue at this time. I'd now like to turn the call back over to today's speakers for any additional or closing remarks. .
report data from the dose escalation stage of the 065-101 study of oral fadra in patients with advanced solid tumors and lymphoma at the ASCO 2024 Annual Meeting, report interim data from initial cohorts in Phase II, open-label, proof-of-concept part of 065-101 study with oral fadraciclib 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. .
Thank you, sir. This does conclude today's program. Thank you for your participation. You may disconnect at any time..
