Earnings Conference Call
Bio-Path Q2 2024
00:00 / 00:00

There are 4 speakers on the call.

Operator

Good morning, ladies and gentlemen. Welcome to the Bio Path Holdings Second Quarter 2024 Earnings Conference Call. At this time, all participants are in a listen only mode. Following the formal remarks, we will open the call up to your questions. At this time, I'd like to turn the floor over to Will O'Connor of Stern Investor Relations.

Operator

Please proceed.

Speaker 1

Thank you, operator. Welcome to the Bio Path Holdings conference call and webcast to review the company's Q2 2024 financial results and to provide an update on recent pipeline and corporate developments. Earlier, we issued a press release, which outlines the topics that we plan to discuss on today's call. The release is available at biopathholdings.com. With me today from Bio Path are President and CEO, Peter Nielsen and Senior Vice President of Finance, Accounting and Administration, Anthony Price.

Speaker 1

Before we begin the call, I'd like to remind you that today's discussion will contain forward looking statements that involve risks and uncertainties. These risks and uncertainties are outlined in today's press release and in the company's recent filings with the Securities and Exchange Commission, which we urge you to read. Our actual results may differ materially from what is discussed on today's call. With that, I'll now turn the call over to Bio Path's CEO, Peter Nielsen.

Speaker 2

Thanks, Will. Good morning, everyone, and thank you for joining us. The first half of twenty twenty four was an undeniably productive period for Bio Path. I'm extremely proud of our team, which continues to efficiently operate on all cylinders and has executed our strategy to achieve both clinical and corporate objectives. I'll begin this morning with the progress we have made with our lead product candidate prexigebersen.

Speaker 2

In June, we were honored to have a presence at 2 of the most prestigious medical meetings in the field of oncology, the American Society of Clinical Oncology or ASCO Annual Meeting in Chicago and the European Hematology Association or EHA Congress in Madrid. At both meetings, we showcased interim results from our Phase 2 study of prexigebersen in combination with frontline therapy decitabine and venetoclax for the treatment of acute myeloid leukemia or AML. At ASCO, we were recognized with an oral presentation of our results. As you know, the study is an amended Stage 2 of our Phase 2 trial in AML. It is an open label 2 stage multicenter study of prexigebersen in combination with decitabine and venetoclax in 2 cohorts of patients with previously untreated AML and refractory relapsed AML.

Speaker 2

A 3rd cohort includes the treatment of refractory relapsed AML patients who are venetoclax resistant or intolerant with the 2 drug combination of prexigebersen and decitabine. The primary endpoint for this study will be the number of patients who achieved complete remission, which includes complete remission with incomplete hematologic recovery and complete remission with partial hematologic recovery. The interim efficacy data presented at ASCO and EHA were from the initial interim analysis of Cohort 1 and Cohort 2. These compelling data showed that prexigebersen based combination therapy was not only safely administered in Cohort 1 and Cohort 2, the high risk newly diagnosed and refractory relapsed AML patients considered unsuitable for standard chemotherapy, but also demonstrated efficacy signals better than current therapies. This is particularly encouraging as refractory relapse patients are a challenging population in which current treatment options are suboptimal.

Speaker 2

It was a pleasure to present these data to an audience of world leading oncologists who treat AML patients and understand the continued great need for new therapeutic options. During the Q2, we also announced the exciting development of a molecular biomarker package to accompany prexigebersen treatment. The goal here is to identify patients with a genetic profile more likely to respond to treatment, thereby improving the probability of success for this program. The emerging role of biomarkers has enhanced cancer treatment development over the past decade and has become a more common companion to many oncology programs. We will keep you up to date as this cutting edge project advances.

Speaker 2

Turning now to BP1002 program, which targets BCL2. As you know, BCL2 is responsible for driving cell survival in up to 60% of all cancers. High expression of BCL-two has been correlated with poor prognosis for patients diagnosed with AML. Venetoclax has shown activity against the anti apoptotic protein BCL-two and works by neutralizing the proteins BH3 domain. It is an improved treatment for chronic lymphocytic leukemia or CLL patients and untreated AML patients.

Speaker 2

However, with the exception of some patients treated with allogeneic hematopoietic cell transplantation, disease relapse invariably occurs often times due to BH3 domain mutation over time. BP1002 also targets the Bcl-two protein. However, BP1002 activity is based on blocking the BCL2 messenger RNA and not the BH3 domain. As a result, we believe that BP1002 could provide an alternative for venetoclax patients who have relapsed, including AML patients who previously received venetoclax treatments. During the Q2, we announced completion of the 2nd dose cohort for the dose escalation portion of our Phase 1, 1b clinical trial of BP1002 hundred and two to treat relapsed refractory relapsed AML including venetoclax resistant patients.

Speaker 2

A total of 3 E value patients per dosing cohort are scheduled to be treated with BP1002 monotherapy in a standard 3 plus 3 design, unless there is a dose limiting toxicity, which would require an additional 3 patients tested. The 1st dose cohort consisted of a starting dose of 20 milligram per square meter and there is no dose limiting toxicity. The approved treatment cycle is 2 doses per week over 4 weeks for a total of 8 doses administered over 28 days. The Phase 1b portion of the study is expected to commence after completion of BP1002 monotherapy cohorts and will assess the safety and efficacy of BP1002 in combination with decitabine in refractory relapsed AML patients. We look forward to keeping you apprised of our progress here.

Speaker 2

Next, let's turn to our Phase 1, 1b clinical trial of BP1001A in patients with solid tumors, including ovarian, endometrial, pancreatic and triple negative breast cancer. Some of the most challenging cancers to treat with today's therapeutic toolkit. BP1001 A is a modified product from prexigebersen sharing the same drug substance with enhanced nanoparticle properties. This trial is being conducted at several leading cancer centers and will initially evaluate the safety in solid tumor patients. Patients diagnosed with recurrent ovarian and endometrial cancer often have poor outcomes and it is our hope that we may provide clinical benefit to such patients.

Speaker 2

We look forward to cohort completion and data readout from this study potentially later this year. Finally, let's review the progress we've made with BP1003, which targets the STAT3 protein. STAT3 is a transcription factor that regulates various tumorigenic processes such as tumor proliferation, metastasis and drug resistance. Its overexpression and aberrant activation characterize many cancers including breast, lung, ovarian, liver and colon cancer. Activation of a STAT3 pathway in breast and ovarian cancer cells promotes tumor initiation, migration and taxol resistance.

Speaker 2

STAT3 also promotes 5 FU resistance in colorectal cancer cells. Its role in numerous malignancies made STAT3 a potential cancer therapeutic target. BP1003 is a novel liposome incorporated STAT3 antisense oligodeoxynucleotide that efficiently reduces STAT3 expression and enhances the sensitivity of breast and ovarian cancer cells, the taxyl and five FU. These results are in line with previous work in which BP1003 plus gemcitabine displayed enhanced antitumor activity in pancreatic ductal adenocarcinoma. Together, these results strongly suggest BP1003 combination therapy is a novel strategy for patients with advanced solid tumors.

Speaker 2

After an extended period of testing, we have identified a method for oligo detection in plasma that we expect will enable us to complete final safety testing needed to finalize an investigational new drug or IND application for submission to the FDA. We are particularly excited to launch our 1st in human validation of this cutting edge therapy in an especially challenging cancer indication that has limited treatment options. Before I turn the call over to Anthony for a review of our financial quarter results, I'd like to highlight that we've strengthened our balance sheet in recent weeks with a $4,000,000 financing. This additional funding provides the financial underpinning from which to execute on our clinical development plan. With that, I'll now turn the program over to Anthony Price for a brief review of our financials along with balance sheet highlights.

Speaker 2

Anthony?

Speaker 3

Thanks, Peter. The company reported a net loss of $1,900,000 or $1.16 per share for the 3 months ended June 30, 2024, compared to a net loss of $4,200,000 or $10.64 per share for the 3 months ended June 30, 2023. Research and development expense for the 3 months ended June 30, 2024 decreased to $1,900,000 compared to $3,100,000 for the 3 months ended June 30, 2023, primarily due to decreased manufacturing expenses related to drug product releases, partially offset by an increase in expense related to our clinical trial for BP1002 in lymphoma due to increased patient enrollment in 2024. General and administrative expense for the 3 months ended June 30, 2024 June 30, 2023 was $1,200,000 As of June 30, 2024, the company had cash of $4,000,000 compared to $1,100,000 as of December 31, 2023. Net cash used in operating activities for the 6 months ended June 30, 2024 was 4,300,000 dollars compared to $6,900,000 for the comparable period in 2023.

Speaker 3

Net cash provided by financing activities for the 6 months ended June 30, 2024 was 7,200,000 With that, I'll now turn the call back over to Peter.

Speaker 2

Thanks, Anthony. As you can see from the data we presented last quarter, we are well on our way to establishing our DNAbilize platform as a better path for cancer patients. We are paving the way for a revolutionary treatment of disease by taking a gentler path. As positive data continues to flow from our clinical trials, we're becoming even more excited about bringing these potentially life saving therapies to some of the most fragile oncology patients. We know this is an ambitious commitment, but we have confidence in our approach and conviction in our mission to give previously untreatable cancer patients a fighting chance.

Speaker 2

With that operator, we are ready to open the call for questions.

Operator

And ladies and gentlemen, we appear to have no questions today. So I will turn the floor back over to Peter Nielsen for any closing comments.

Speaker 2

Thank you again for joining us and for your continued support of Bio Path. Have a great day.

Operator

And ladies and gentlemen, thank you again for joining us today. This concludes today's presentation. We do thank you for joining. Have a great rest of the day.
