Now I'd like to turn the call over to Antonino Morales. Antonino?
Thank you, Jody. Good afternoon, everyone, and thank you for joining us. I'd like to extend a particular welcome to Dr. Seema Nagpal, who is joining us on today's call. Dr. Nagpal is a board-certified neuro-oncologist at Stanford University and is also a supporter and early adopter of our proprietary cerebrospinal fluid assay, CNSide. In a few minutes, she will discuss how she uses CNSide in her practice. We are convinced more than ever before that CNSide is a highly valuable asset and that pursuing its further development is critical to the management of patients with cancer involvement in the central nervous system. Additionally, we believe this is the optimal path forward for building a sustainable business and generating value for our shareholders. In fact, independent research indicates that the initial annual U.S. addressable market for CNSide is about $1.2 billion.
Our goal is to establish CNSide as a standard of care under the National Comprehensive Cancer Network, or NCCN, guidelines, which we believe will support further physician adoption and will set reimbursement at a rate that reflects the value of our test in clinical decision-making. We have a strategy in place to reach this goal, providing us with a clear path forward. You may recall that CNSide was developed based on Biocept's longstanding and proprietary liquid biopsy technology. Our assay is the first commercially available method that has the potential to objectively measure tumor status and therapy response in patients with brain tumors by quantifying the tumor cells in the cerebrospinal fluid of patients with cancer that has metastasized to the central nervous system.
It's a laboratory-developed test that can help physicians be better informed about the actionable molecular information associated with a patient's metastatic cancer and allows development of personalized cancer treatment plans. CNSide is unique in its ability to answer three key questions. Number one: Is there a tumor? The CNSide assay detects and quantifies tumor cells in cerebrospinal fluid in patients with carcinomas or melanomas with suspected central nervous system metastasis. Number two: Is there a target? The CNSide assay can identify actionable biomarkers for which targeted therapies are available. And number three: Is there a trend? The CNSide assay can monitor tumor cell count, which may be indicative of response to therapy or disease progression.
Given that CNSide is not yet recognized as standard of care, we can only bill for components of our testing using existing CPT codes, and this level of billing does not cover our test costs. Therefore, we are focused on pursuing standard of care status for CNSide through the NCCN guidelines to support further adoption and reimbursement that aligns with our test value. To accomplish this, we need to provide evidence of CNSide's clinical utility for physicians in their treatment decision-making. We are in the process of generating evidence in the form of data from our FORESEE prospective clinical trial and peer-reviewed publications, both of which I will speak about momentarily. While we anticipate increased physician adoption and launching full commercialization upon securing standard of care status, I want to mention that early adoption from the physician community is highly promising.
We launched CNSide in the first quarter of 2020. By the end of Q2 of this year, CNSide had been used by more than 200 physicians for over 1,400 patients at more than 100 different institutions. The cumulative number of CNSide tests we have run to date exceeds 2,800. We believe the strong early adoption, along with the fact that many physicians are reordering the test, shows CNSide is a useful tool in supporting physicians in managing their patients with central nervous system metastasis. In our quest to produce additional clinical utility, we have a dual approach strategy. First, is our ongoing prospective FORESEE trial, which measures the impact of CNSide on physicians' clinical decision-making to manage leptomeningeal metastasis, or LM. This is a devastating cancer in the membranes that surround the brain and spinal cord, with few treatment options.
The trial is also designed to compare CNSide cell detection in the cerebrospinal fluid to that of conventional cytology. CNSide has notable advantages over current standards of care, such as cytology, clinical evaluation, and MRI, which have limited sensitivity and specificity. In fact, it's notable that 40% of patients who test positive for LM at autopsy tested negative for LM through cytology prior to death. These limitations create challenges for physicians in managing disease and determining the best course of treatment for very sick patients. In pilot studies, our test has shown 92% sensitivity and 95% specificity, 95% specificity in detecting LM. Additionally, CNSide is both qualitative and quantitative, which are key to monitoring the treatment response and improving the ability of physicians to make or change treatment decisions. This is becoming increasingly important as more targeted therapies are approved by regulators.
FORESEE is a two-part prospective clinical trial that's enrolling subjects with breast or non-small cell lung cancer as the primary tumor, and who have suspected or confirmed LM involvement. We began enrolling subjects in the feasibility phase of the study in March, which will include up to 40 subjects. I'm pleased to report that we are well ahead of our projections, with 33 subjects enrolled as of August 28th, at clinical sites that include Stanford University, the University of Texas Southwestern Medical Center, Northwestern University Feinberg School of Medicine, and Fred Hutchinson Cancer Center, University of Washington. The trial is designed to follow subjects and collect data from each enrollee at four key time points in their treatment. As of last week, we collected data points from 55 visits.
We anticipate completing the feasibility phase of this study in the first half of 2024, and moving into the second part of the study, which is the validation phase, at that time. Between 40 and 100 subjects will be enrolled in that phase. We expect two additional medical centers to join the FORESEE trial in the near term to help with future enrollment. The second strategy to generate additional clinical utility evidence is through the publication of study data in peer-reviewed journals. We are pleased that five manuscripts are in process for publication. One article, authored by Dr. Sonam Puri from Huntsman Cancer Institute in Salt Lake City, has been submitted recently to the journal Neuro-Oncology Advances.
It describes how CNSide was used for diagnosing and monitoring response to therapy on 15 unique patients treated at that facility, having non-small cell lung cancer with suspected or confirmed LM. A second paper reviewing the fundamentals of the CNSide technology has been submitted by our team at Biocept to the Archives of Pathology & Laboratory Medicine. Complementing this publication strategy, CNSide was featured in two oral presentations at the SNO/ASCO CNS Cancer Conference held earlier this month. It's highly gratifying to have leaders in the field, such as Dr. Priya Kumthekar from Northwestern and Dr. David Piccioni at the University of California, San Diego, discussing CNSide at one of the most prestigious annual gatherings of neuro-oncologists and other physicians, as they share breakthroughs in detecting and treating cancers of central nervous system.
At this time, I am exceptionally pleased to turn the call over to Dr. Nagpal, who will discuss how she is using CNSide with her patients. Dr. Nagpal?
Thank you for your introduction, Antonino. I'm very excited and pleased to share my experience using the CNSide test and, and that of Stanford University to help our patients. I have been using CNSide since it first became available in April 2020. Before I had access to this test, it was challenging to diagnose my patients with leptomeningeal disease and identify actionable biomarkers for response to therapy. Prior to availability of this test, I was relying solely on pathology results, which have poor sensitivity and specificity in combination with you know, looking at my patients, seeing what they look like, and MRI, which is also limited in sensitivity and specificity.
These limitations can be really significant obstacles to the treatment of my patients and can really affect their survival and quality of life when I can't get the right answer for them. While in the early days, I used CNSide mainly on patients to sort of rule in or confirm leptomeningeal disease, meaning like I was fairly certain that's what it was, but I wanted the cell count or I really wanted the biomarkers. I've now kinda transitioned a bit more to using it more broadly, and I'm using it to rule out leptomeningeal disease in patients. And that is a little bit different. It might not be as easy to appreciate, but it is just as important to rule out the disease as it is to rule it in.
You know, one in 10 women in this country will develop breast cancer at some point, and it may be treated and cured, and then sometime later, they may show up with abnormal enhancement on their brain MRI that may be completely unrelated. And it's particularly important to figure out that that new enhancement is not related to the breast cancer. It is not leptomeningeal disease, because treatments to the brain and central nervous system have really serious side effects. For instance, probably one of the most common treatment methods we use is brain radiation. And for leptomeningeal disease, it's the whole entire brain and sometimes the spinal cord. While it reduces cancer progression in the central nervous system, it is also notorious for damaging healthy brain.
What this translates to for patients and families is early dementia, and that can be seen within three to six months of the treatment. So if, for example, that breast cancer patient actually just has a little bit of inflammation from something completely different, doing whole-brain radiation really, really, really causes harm. So I don't wanna harm my patients, but I also wanna make sure I'm treating the right thing. So without an adequate diagnostic test, you can tell that this is a real challenge. And I gave you that one particular example, but that patient is one of at least two or three in the past year where I've been able to convince their treatment team and the patient that they actually don't have leptomeningeal metastases, and therefore, we should not do these really harmful treatments.
And actually, that particular piece of using CNSide has expanded the number of physicians using CNSide at Stanford. So I use it all the time for patients within the cancer center for our breast, lung, melanoma oncologist, but now general neurology is asking to use this test on patients who are in the hospital. Hey, they have a little bit of abnormal enhancement on their MRI. They have maybe a remote prior history of cancer. Is this cancer? And it's a really important question to answer and to answer correctly. So I'm in agreement with you, Antonino. This is a incredibly important test. It's really important information, and I think once it's in the hands of a physician, we figure out how to use it, and we don't wanna, we don't wanna lose it. So thank you.
Thank you for those comments, Dr. Nagpal, and sincerely thank you for taking time from your very busy schedule to join us this afternoon. Before we open the call to your questions, I want to mention another important action we are taking to help us reach our goal of standard of care status for CNSide. For more than a year, we have focused on right-sizing our business and taking other steps to extend our cash runway. You may have seen in our most recent financial news release that we have significantly reduced operating expenses. Much of our savings have been from trimming our workforce to align with our strategic focus. We now have a purpose-driven and enthusiastic team with the capabilities to advance our strategy.
Additional man, a dditional measures to manage our spend have included simplifying test ordering and reducing the number of microfluidic chips used in CNSide testing. So in summary, I'd like to leave you with two key points. First, we are making progress in generating the requisite prospective clinical evidence to support CNSide as standard of care under NCCN guidelines, an achievement that we believe will support further physician adoption and set reimbursement. And second, we are carefully managing our expenses to extend our cash runway. As always, we are committed to improving treatment decisions for physicians and enhancing clinical outcomes for patients. With that overview, we are ready to take your questions.
Key, then the number one on your telephone. If your question has been answered and you wish to withdraw your request, you may do so by pressing star, then two. If you are using a speakerphone, please pick up your handset before entering your request. One moment, please, for the first question.
Before we take your first question, I'd like to mention that Biocept will be participating virtually in the H.C. Wainwright Global Investment Conference being held September 11th through 13th. A webcast of our presentation will go live on September 11th on the Events and Presentations page of our website at biocept.com. Okay, operator, we are ready for the first question.
The first question today comes from Michael Okunewitch with Maxim Group. Please go ahead.
Hey, guys. Thank you for taking my questions today. I guess to start off, I'd just like to ask a little bit about the process of gaining inclusion into guidelines. Are you still expecting that the feasibility portion of the FORESEE study will support that inclusion as well as sufficient reimbursement, or do you think you'll need the validation portion as well?
Michael, again, thank you for joining us today. We believe that completing the feasibility study will be sufficient for us to submit our application to the NCCN guidelines so that we can become included in their standard of care, as standard of care.
All right, thank you. And then, as for the validation portion, right, if the feasibility is enough for the guidelines and for reimbursement, what's the goal of the larger second portion of the study?
You know, we would eventually, i f the feasibility study provides the kind of data that would support us support the submission to the NCCN, we would consider actually terminating that second half of the validation phase because it would no longer be necessary.
All right, thank you. And then, I actually do have a question for Dr. Nagpal. Could you talk a little bit more about what signs you would look for and to figure out whether or not you should consider a rule out test for LM? And then if you didn't have CNSide, you know, what would you do with these patients where you're not entirely sure whether or not they do have LM and you're considering potentially damaging treatments?
I believe Dr. Nagpal has signed off. She is, you know, a practicing physician, so she wasn't able to stay on the call. I believe Dr. Barbara Blouw can take your question, though, Michael.
Yeah, Michael, this is Dr. Barbara Blouw. I will relay that question to Dr. Nagpal, and we will provide you with an answer today or tomorrow.
All right. Thank you. I appreciate that. And then just one more for me, and I'll hop back in the queue.
All right.
I'd just like to see what level of reimbursement you would need in order to justify a greater mass marketing effort for CNSide.
What reimbursement, level of reimbursement we're looking for? I guess I need, c an you repeat that question? You broke up, Michael.
Oh, sorry. I was saying, what level of reimbursement would you need for CNSide to make it worth it to justify a greater commercial marketing effort?
Our expectation actually is that, you know, we've looked and explored that question and we expect that this test could potentially have a pricing of about $5,000-$6,000 or so. However, and that is not what we need to make a profit. That is much more than what we need. Right now, our cost to process the test is a little bit less than $1,000.
All right. Thank you very much, and looking forward to additional progress.
Thanks, Michael.
The next question comes from Kemp Dolliver with Brookline Capital Markets. Please go ahead.
All right, thank you. Looking at the enrollment data you provided, so generates a couple of questions. First, has the pace of enrollment, you know, changed since you started in March?
Actually, that's a very, K emp, by the way, thank you for joining us, and that's a very good question. We are actually ahead of schedule. The pace, you know, started very strongly and continues at a very strong pace. We had originally anticipated completing the first phase enrollment by the end of this year. We expect to complete it by the end of September. So we're well ahead of schedule.
Okay, fine. That was my second question, and just doing the arithmetic around the enrollment so far. So, that comment's encouraging. So you complete enrollment in September. You know, how does the timeframe, how does the cadence move there? Say, if a certain number of visits over a certain number of time frame, it's a little more general than that. You know, assuming that you do complete enrollment in September, are we looking at, say, January for having data?
No, we expect to have data by before the end of the first half of next year. You know, there's some unknowns for us. Obviously, we have patients that expire, and so that kind of changes the numbers a little bit. But, we are on track to have data available before the mid part of next year, and that data is what we would use to submit to NCCN.
Okay, very good. And then, you did touch on this in your prepared comments, but what further steps are you considering near term to extend the cash runway farther into next year?
Yeah, we continue to evaluate, and this, I think, Kemp, you're aware, well, this started back in February of 2022, where we started, you know, reducing headcount and looking at creating efficiencies in our laboratory and all areas of the business. That's an ongoing process. And, as we move forward, we continue to identify more efficiencies in the laboratory. But also as we have, you know, reduced or right-sized our business and not focusing on the commercial side of the business, we also have some other areas at the administrative side that we are able to reduce as well. So there are, we continue to look at that. It's an ongoing task.
Right. And I think you had talked about the, office space, and that's, that being a substantial opportunity. Is that still in process or?
Yes, we have ongoing conversations with our landlord at this point in time, considering various options to reduce the expenses associated with the building that we're in right now. As you know, the most critical part for us is the laboratory. Previous management took over this larger space when they geared up for the COVID testing. Given the fact that we're not doing COVID testing anymore, there's some excess space here that we are definitely looking at ways to reduce the expenses associated with that space.
Very good. Thank you for taking my questions.
Thank you, Kemp.
This concludes our question and answer session. I would like to turn the conference back over to Antonino Morales for any closing remarks.
Thank you. Once again, I'd like to thank everyone for participating on today's call and for your interest in Biocept. We look forward to providing an update during our next conference call in November, when we resume holding these events on a quarterly basis when reporting financial results. Thanks again, and have a great day.
The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
