InvestingPro Insights
In light of Sangamo Therapeutics' recent earnings call and their strategic financial planning, several key metrics from InvestingPro provide deeper insights into the company's current financial health and market performance. Sangamo Therapeutics, with a market capitalization of $114.87 million, is navigating through a challenging financial landscape. The company's price-to-book ratio as of Q1 2024 stands at 1.39, which might suggest that the company's assets are reasonably valued in the market, considering the industry standards.
An InvestingPro Tip worth noting is the company's high shareholder yield, which could be an attractive point for investors looking for companies with potential returns on their investments. However, it's important to consider that Sangamo is quickly burning through cash, which aligns with the company's own admission of the need for additional capital to sustain operations beyond Q3 2024.
Furthermore, analysts do not anticipate the company will be profitable this year, which is consistent with the reported revenue decline of -92.22% over the last twelve months as of Q1 2024. This sharp decline in revenue highlights the importance of the company's efforts to secure additional funding and partnerships to advance its neurology pipeline and gene therapy programs.

Sandy Macrae: Thank you, Louise, and good afternoon to everyone joining the call. I'm very pleased to be speaking to you today from the American Society of Cell and Gene Therapy Annual Meeting in Baltimore, where we have been presenting important preclinical data from our epigenetic regulators, AAV capsid delivery platform, and next generation genomic engineering platform. These data showcase both the depth of Sangamo’s neurology pipeline and the power of our scientific capabilities, which we believe provide strong opportunities to advance programs ourselves and with potential partners. In order to progress these compelling programs, Sangamo must be well capitalized. The leadership team and I have been laser focused on addressing our funding needs. In late March, we were pleased to announce a registered direct offering with institutional shareholders, including an important existing investor, that raised approximately $24 million in gross proceeds. This was a significant development, and we are thankful for their support of our science and our mission. That was, however, the first step in our current journey to securing additional funding. I would like to emphasize that we are resolutely focused on building upon this foundation to position Sangamo for long-term success. That continues to be my number one priority. Business development is an important part of these efforts, and I am pleased with the progress that was being made on this front. We are currently engaged in very encouraging conversations with multiple potential partners across our portfolio, including our Fabry disease program, our novel STAC BBB engineered capsid, our pre-clinical neurology product candidates and our next generation genome engineering capabilities. I understand your desire to hear more concrete news on this front, but we are unable to share more until any potential transaction is finalized. Be assured that we are encouraged by the progress of these discussions and hope to announce news of one or more transactions. Over recent months, Sangamo has presented important preclinical data that solidify our sharpened focus in neurology, validate our differentiated science, and help contextualize why we made this important decision to dedicate ourselves to addressing neurological disorders. In March, we were proud to share remarkable preclinical data from our new intravenously administered neurotropic AAV capsid, which demonstrated industry-leading blood-brain barrier penetration and brain transduction in non-human primates. This novel capsid, STAC BBB, showed robust penetration of the blood-brain barrier with 700-fold higher transgene expression in neurons, compared to the benchmark capsid AAV9 and outperformed all other known published capsid variants evaluated in the study. Combined with our potent epigenetic regulation cargo, we showed robust, stacked BBB-mediated expression of zinc finger cargo in neurons with potent and widespread repression of the Prion and tau genes observed across all key brain areas, illustrating the exciting potential to modify disease progression in Prion disease and various tauopathies. These data support further advancement of our Prion and tau programs, which we are on track for regulatory submissions sent to the clinic by the end of 2025. Meanwhile, we continue to advance our lead candidate in chronic neuropathic pain NAV 1.7, which uses an established intrathecally administered capsid toward an IND submission expected in the fourth quarter of this year. We believe our ability to combine potent sink finger epigenetic regulation payloads with exciting new industry-leading capsid delivery technology, could unlock significant potential for the treatment of devastating neurological diseases, indications for which delivery of treatments to the central nervous system has historically proved challenging. Building on this, we are proud to be presenting three platform presentations and 17 posters at this week's ASGCT annual meeting. These presentations showcase the depth of our neurology pipeline, including various applications for our zinc finger epigenetic regulation platform, exciting advances in our capsid delivery technology, and the discovery of potentially transformative next generation integrase technology engineered to enable large-scale genome editing. In epigenetic regulation, we have shared advances in zinc finger activators and repressors for the potential treatment of a remarkable range of neurological diseases, such as prion disease, tauopathies, Charcot-Marie-Tooth diseases type 1A and 2A, Dravet Syndrome, SOD-1 mediated amyotrophic lateral sclerosis or ALS, Phelan-McDermid syndrome, Parkinson’s disease, Angelman syndrome, and other neurology disorders. We have also demonstrated Sangamo’s potent delivery capabilities developed through our AAV capsid engineering platform, SIFTER. Here we have presented additional STAC BBB findings, including prion and tau repression data achieved via STAC BBB delivery. We also presented for the first time exciting initial findings for a possible mechanism supporting how STAC BBB may cross the blood-brain barrier. Our SIFTER platform is designed to engineer capsid for various routes of administration such as intrathecal and intravenous delivery. SIFTER can also engineer capsid for in vitro discovery. So in a platform presentation tomorrow, we will present findings from STAC 150, a novel capsid that's been shown to be highly potent in neurons and enables high throughput screening of neurology-focused transcriptional regulators. We anticipate the STAG 150, which we believe manufactures easily at small scale, will help accelerate the discovery of potent and highly specific epigenetic regulators. Finally, building on our deep expertise in that protein-DNA interactions derived from our zinc finger platform, we presented for the first time a potentially breakthrough new approach for integrating large sequences of DNA into the genome to potentially treat, with a single medicine, patients who have unique mutations in the same gene. Precisely integrating large synthetic DNA constructs into a desirable chromosomal site has been the dream for people working in this field for many years. Our modular integrase or MINT, platform is a versatile, protein-guided genome editing method that understands and engineers Bxb1, a serum-serine recombinase to insert or replace entire genes and adds to Sangamo’s toolbox of editing capabilities. We are hopeful that our MINT platform could be used to correct many disease-causing mutations in a diverse patient population by inserting a correct copy of the gene into its natural locus. MINTs could be deployed internally for various neurological indications, but also provide potential partnering opportunities both for human disease and in agricultural biotech settings. We are already in active discussions with potential partners about our integrates capabilities and are hopeful that MINT could provide us with another potential non-dilutive funding opportunity. Alongside our presentations on this topic at ASGCT this week, we have also published a manuscript in Bioarchive further outlining these next generation integrase advancements, which is also available on the publications page of the website. I encourage you to learn more about this exciting development in the field of genomic medicines. Now, looking at our clinical programs, we have made strong advances in the first quarter for our Fabry disease program, having dosed the final patient in the Phase 1/2 STAR study of isaralgagene civaparvovec, our investigational gene therapy for the treatment of Fabry disease. With 33 patients now dosed, screening, enrollment, and dosing are complete. One additional patient has been able to stop enzyme replacement therapy, or ERT, resulting in a total of 14 patients withdrawn from ERT to-date. The four remaining patients dozed since February 2024, who began the study on ERT, already have plans in place to withdraw ER treatment at the appropriate time. At the 20th Annual World Symposium in February, we presented compelling updated preliminary clinical data from the STAR study showing sustained benefit and a differentiated safety profile. These results underscored the program's potential as a single administration treatment for Fabry disease. As a reminder, this quarter we announced alignment with the U.S. FDA on an abbreviated pathway to potential approval. We've also been granted prime eligibility by the European Medicines Agency and ILAP designation by the U.K. Medicine and healthcare products regulatory agency. We are engaged in active discussions with potential collaborator partners for our Fabry disease program and continue to defer additional investments and planning for a potential registrational trial until a collaboration partnership or financing for this program is secured. Moving to our partner clinical program, we look forward to the pivotal readout expected in mid-2024 in the Phase 3 affine trial of giroctocogene fitelparvovec, an investigational gene therapy we're developing with Pfizer for patients with moderately severe to severe hemophilia A. Pfizer anticipates submitting a biologics license application and a marketing authorization application in early 2025 if the pivotal readout is supportive. As a reminder, we are eligible to earn up to $220 million in milestone payments and up to 14% to 20% royalties on potential sales from this program. We end the quarter with approximately $54 million in available cash and cash equivalents, which includes funds from the aforementioned registered direct offering. We believe these resources, in combination with this cost savings expected from the recent restructurings, workforce reduction and other potential cost reductions, will be sufficient to fund our planned operations into the third quarter of 2024. As I outlined earlier, we are actively pursuing a range of different options to raise important additional capital and encouraged by the business development discussions ongoing across our Fabry Program, Capsid Engineering and Next Generation Genome Engineering efforts. We believe our company has the science required to potentially transform the lives of patients living with devastating neurological conditions and are committed to raising the funding required as we seek to make our vision a reality. Operator, please open the lines for questions.
Operator: Thank you. At this time we will conduct a question-and-answer session. [Operator Instructions] Our first question comes from the line of James Stamos at Jefferies. James, your line is open.
James Stamos: Hi, this is James on for Maury Raycroft. Congrats on the progress and thanks for taking our question. I just wanted to ask, where are you with preclinical and GLP tox studies with Stack BBB and what are your latest thoughts on which targets or indications would make the most sense to partner or keep in house?
Sandy Macrae: Thank you for your question. We have made one of the reasons that we like Stack BBB so much is that our manufacturing team have been able to work with it and found that it is very manufacturable. They can take it so far up to 50-liter scale and are going higher, that they can use the same purification and assay techniques and that it feels like a capsid that will be able to give us great yield and also be able to use many of the processes in CMC work that really is underappreciated in the importance of capsid selection. We've said publicly that we are moving ahead with tau and with prion. You could imagine the amount of external interest in tau, not just because it's a high unmet medical need, but because the capsid gives you the brain penetration and widespread delivery that's needed. And our zinc finger repressors are really unique in being able to almost switch off tau in the cells that they can get to. We are having many discussions with companies about our capsid and will choose wisely, I believe, which ones we partner and which ones we take forward ourselves. What we understand and I want to say this again and repeat what I said in the chosen words is that we understand the need to bring in money to the company and that's always a balance between the desire that we have to take things forward and the money that's available from many of the partnerships I'm sure we will achieve in the coming weeks.
James Stamos: Great. That's very helpful. And just to go on to like some of the more specialized parts of your ASGCT presentation, can you talk about the importance of targeting the pons and motor neurons and Alzheimer's. And are there any other companies that you're aware of that have the ability to target these sites?
Sandy Macrae: I think, thank you for your question. It's really been a remarkable ASGCT and the field moves closer to these tools being able to address such important disease. Amy, can you talk a little about this? I know this is one of your passions.
Amy Pooler: Yes, I would love to. Thank you for the great question. And what's really important here is being able to target brain regions that would be traditionally challenging to target using something like a direct injection approach. The pons being part of the brain stem is not a region that you would necessarily want to reach using a direct injection guided approach, even for the most severe of diseases. So we were so excited to see the biodistribution that was able to be achieved with the Stack BBB capsid, especially for what it means for the tau program. The pons is critical in progressive super nuclear palsy, but also other tauopathies like Alzheimer's disease. In addition, as you notice, the motor cortex, which is part of the frontal cortex, we use this as an example of how Stack BBB is able to transduce those cortical neurons. Really, we believe that this kind of widespread brain targeting is critical for halting or slowing the progression of the disease.
Sandy Macrae: Thanks, Amy.
James Stamos: Great. Thank you for taking our questions. I'll hop back in the queue.
Operator: Thank you very much. One moment for our next question, please. Our next question comes from Gena Wang of Barclays. Gena, your line is open.
Gena Wang: Thank you for taking my questions. I have two, the first one also is about the Stack BBB and it seems like very exciting new capsid. What is the highest dose you used in non-human primates? And what is the limiting dose toxicity there? And then the second question quickly regarding the Hem A, I know it's your partner Pfizer's is in charge, but just wondering for the mid-24 Phase 3 update, would that be just a press release from Pfizer? And then for the 220 milestone payment, the first milestone is that the drug approval and is that a big portion of the $220 million?
Sandy Macrae: Gena, thank you for your questions and I know you've been following Hem A for a great deal of time. So it's good to be coming closer to the point where it gets to registration and approval. So let me pass this on to two people. Amy, can you talk about the dose that we've used and whether there was any toxicity, please?
Amy Pooler: Yes, absolutely. As part of the Stack BBB study that we discussed yesterday, and we also will discuss later today at the poster session at ASGCT, we performed a dose range finding study with our tau and zinc, clinical lead zinc finger, and we did three different doses, and the top dose was 1e14. We were really happy to see that with the histopathology results that we didn't see any dose-limiting toxicity and really no findings in the brain, the spinal cord, or the liver, or these peripheral organs. So, really, really positive and encouraging data.
Sandy Macrae: Gena, does that answer your question? Is there any follow-up?
Gena Wang: Yes, like more thinking like other than you know the dose finding, like what is the highest dose you tested for the safety toxicology perspective?
Sandy Macrae: 1e14. So 1e14.
Gena Wang: That's 1e14. Okay. That's it.
Sandy Macrae: It's the highest we've -- so we went there in the efficacy study that we just reported and we really saw nothing, sorry, we saw nothing that would give us any concern. We will now go into the GMP tox study which is the only thing remaining to complete the IND enabling studies for that. But we will clearly start at a lower dose in the clinical study because that's the right thing to do and that's what the agency will ask us to do. But thus far, we’ve -- it's a very clean capsid, which is great, great news. And then can we talk about humane, Natalie? I know you've been speaking to your friends at Pfizer regularly.
Nathalie Dubois-Stringfellow: Sure, sure. Yes, we're very excited that the mid-2024 pivotal readout in MA is coming up soon. The partnership allows for 220 million in potential milestone and 14% to 20% royalty on potential sale. But the specific amount of each milestone is not publicly disclosed. But this could start as early as the start of 2025, if the pivotal readout is positive and if Pfizer would like to see regulatory approval to the program.
Sandy Macrae: And Gena, just to reflect on that, and we're limited in what we can say. When you sign these deals, there's always an agreement about who talks about what. But the regulatory milestones, which are we get one for the U.S., one for Europe and one for Japan, are not for approval, they're for submission of the package. And then the commercial milestones, which are for first patient dose rather than for reaching a certain sales threshold. So they're very, very favorable milestones that will fund the company in ‘25 and ‘26.
Gena Wang: Very helpful. Thank you.
Nathalie Dubois-Stringfellow: Yes, I need to mention that the significant portion of the 220 million is near-term and we could also choose to monetize them now.
Sandy Macrae: Yes, so the closer -- so Gena the closer we get to the -- when data is revealed and then when Pfizer submits this, we have the option of monetizing those royalties, but we can also choose to wait and use them to fund ‘25 and ‘26. And what will make that decision is the non-dilutive funding from business development that we do now will tell us whether we need to make that decision. We are -- I know that there's a concern from people that followed us for a long time about our near-term cash runway. We feel that we are fortunate to be able to do both capsid deals, fabry deals, technology deals and to have this large amount of cash next year that we can bring forward if necessary.
Gena Wang: Thank you very much.
Sandy Macrae: Thank you, Gena.
Operator: Thank you very much. One moment for our next question, please. Our next question comes from Patrick Trucchio of H.C. Wainwright. Patrick, your line is open.
Luis Santos: Hi everyone, this is Luis Santos for Patrick. Congratulations on the recent progress and your presence, impressive presence at ASGCT. I am interested in knowing if you're already guided to the tau program and if it's going to be in Alzheimer's, do you know which patients you're going to be treating and which other indications you are going to push forward here with the tau program? Then I have a follow-up question.
Sandy Macrae: So thank you for your question. We haven't guided on that. There's been an enormous amount of interest in our presentation yesterday at ASGCT. It clearly was, I think, the most remarkable presentation of all of the many people that are moving forward in blood-brain barrier penetrant capsids. We feel that the tau asset, the cargo that's within it, doubles down, makes this even more interesting. The role of tau in Alzheimer's, I think, is becoming increasingly clear. The biogen data is very encouraging. The idea that it's the thing that is relevant to the clinical stages of tau rather -- of Alzheimer's rather than in the early pre-symptomatic ones makes this a much more easy lift. However, we're very conscious that Alzheimer's studies are large programs and that we need to make sure that we either do ourselves well or partner with someone who has a real expertise in Alzheimer's.
Luis Santos: On the follow-up, thank you, that was helpful. On the follow-up on the -- on partnerships but for the MINT platform, you mentioned that there are business development opportunities there. Do you have any potential collaborators in mind and what diseases would you be targeting?
Sandy Macrae: The MINT integrate is remarkable. The presentation at ASGCT was just 57 minutes ago and there was a lot of excitement in the room about it. We have already been speaking to people for three months on this and I want to put the business development discussions into perspective. We had the regulatory clarity for Fabry, just in February. We had the capsid results just in March. We've finally taken MINT to a place that we feel we can share it in May. So, I understand the desire for signed deals, but the results are going to lead to them have only come out over the past two or three months, which is -- means that at the moment you could imagine our business development group is incredibly busy in talking to lots of people about this. Now, integrase is something that has the potential for really disruptive genomic engineering. It's the kind of thing that David Lou when he was asked said was his dream of what the ideal genomic medicine was, which was an integrase that could be engineered to go to your site of choice and put in pieces of DNA, gene-sized pieces of DNA that would replace all of the mutations downstream. And the team at Sangamo, because of their expertise in understanding the interaction between proteins and DNA from the zinc finger platform have been able to do this remarkable engineering and the whole alpha-fold and understanding artificial intelligence of how you understand proteins has helped this. We feel that this is something that Sangamo can use, but it also has attracted great interest from the hardcore science pharma companies that you could imagine who all see this as the future of genomic engineering. And so we have a responsibility to put it in as many people's hands as possible. I think you will hear more about this MINT platform for some time to come.
Luis Santos: Thank you.
Operator: Thank you very much. One moment for our next question please. Our next question comes from the line of Luca Issi at RBC. Luca, your line is open.
Unidentified Analyst: Oh, great. Thanks for taking our questions. This is Lisa on for Luca. I just want to ask another question on the MINT technology. Just wondering, if you can give us a sense of, you know, what kind of targets here would be good candidates. For instance, would it be possible to integrate something like a full length CFTR gene, which is around roughly 190 kilobases, or should we think about something larger like full-length dystrophin, which is measuring closer to over 2,000 kilobases? Just any color here would be helpful. Thanks.
Sandy Macrae: So you ask really important and interesting questions and as always with Sangamo we've thought about size because as you know zinc fingers are an eighth of the size of crisper and even the small mammoth crispers are 4 times as big as the zinc finger and that's important because of delivery. It's the same with MINT because we've tried to keep the technology as small as possible so as we could put both the integrase and a cargo in an AAV. Now when you get to the size of some of the genes that you're talking about, it comes down to what kind of delivery you're using. My dream for MINT is to be able to drop a cDNA copy of the gene or of the exons that are mutated into intron one of the genome. It would then be run off of the promoter, have all the locus control elements, and it would alleviate the requirement to edit all the individual mutations that usually are the cause of genomic disease. Now to put in a whole genomic copy would be unnecessary, I would argue. And then we need to look at what are the diseases where the cDNA is packageable into the delivery mechanisms that are available because the MINT should be size agnostic and has so far shown great potential. Amy, is there anything else? Amy, I'm aware that you're on the line and as our Head of Research, perhaps you have other things to add to that.
Amy Pooler: No, that's a fantastic explanation, Sandy. I would just add that there are specific genes as well that are involved in some neurological disorders. And I'm thinking of things like Rett syndrome where MECP2 needs to be fine-tuned at a very specific level, something like an integrase where you could integrate in perhaps the healthy copy of Exon 1 or even a bigger portion of the gene, so that it's under control of the endogenous promoter could be really transformative for a disease like that. And so I think it's incredibly exciting to see what are the opportunities around this new MINT platform.
Q -: Thanks so much. Thanks for taking my question.
Operator: Thank you very much. One moment for our next question. Our next question comes from Ritu Baral of TD Cowen. Ritu, your line's open.
Ritu Baral: Hi guys, just a quick question on the Fabry program actually, you've dosed 33 patients. We saw the data at World plus you have the Phase 3 path going forward agreed upon with FDA. What is the next data update that we're going to get from that? And also, I guess, is there a data point or a follow-up point in a subset of patients that's gating to potential business development around or out licensing of this program? Thanks.
Sandy Macrae: Thank you, Ritu. I'm going to pass this on to Natalie, but I'll just remind you again, the whole business development conversation around Fabry changed with Peter's new way of thinking about this at the agency and the conversations that we had in February. And so it's like a new conversation we're having with potential partners. But Natalie, can you address some of the technical pieces, please?
Nathalie Dubois-Stringfellow: Yes, sure. So we've completed the dosing of all the patients in the Phase 1/2, so for a total of 33 patients. We continue to analyze the data, but the body of data that we have thus far is not gate limiting for any partnership and any of the Phase 2B preparation or registrational trial preparation. So, we continue to analyze the data, but we have agreed with the FDA that we have enough data to move on to a Phase 2B. And that's what we're discussing with partners, potential partners.
Ritu Baral: Sandy, when you say that the discussion has changed, are you talking about the structure of the deal that is in Sangamo’s best interest? Like, do you think it could be like a cocoa going forward or is it just really sort of valuation terms that are different now?
Sandy Macrae: I think it's much simpler than that, Ritu. There was a concern that there wasn't clarity about what the regulators were wanting and there was this worry that we've all talked about that it was going to be a head-to-head against ER. And the agency now saying, no, it's a simple single study and that we can -- they've named the number of patients and they've said we can come back halfway through the study and show them the data we've got if we feel it's compelling. I think that has completely changed how the various companies are going to. And I think great credit to Peter, he is walking the talk in this and we have benefited greatly from it as being almost like the poster child for what it is, approval of rare disease gene therapy is.
Ritu Baral: Great, thanks.
Operator: Thank you very much. One moment for our next question.
Sandy Macrae: And if I may, Ritu, we've started the -- we’ve initiated the conversations with the Europeans and uniquely the FDA is volunteering to send one of their staff with us to that conversation because they feel that it’s the way forward for these kind of therapies is for a common approach to them. And I think it reflects the support that we have from the FDA in these discussions.
Ritu Baral: Thanks, Sandy.
Operator: Thank you very much. Our next question comes from the line of Nicole Germino of Truist. Nicole, your line is open.
Bill Chappell: Hi, this is Bill on for Nicole. We have a question, it’s given the uptake for Roctavian, what is the read through to potential uptake for Fabry disease gene therapy?
Sandy Macrae: Thank you for your question. So the Roctavian launch I know has been a subject of great debate. We can't comment on how BioMarin launched it. All I know is the reason that we chose Pfizer to be our partner is I have great confidence that when Pfizer chooses to launch something, they do it well and effectively. And that follows through to our choice of partners for Fabry disease. There are several companies and there are some that are more obvious as being great commercialization engines and great launch companies. What I can tell you is in our conversations with these companies, we have had notes from the patient support groups, who have been very keen to make sure that the pharma partners understand how supportive they are of the results that they have seen in our Fabry program. Because you and I will talk about the biochemistry and the biopsies. What the patients have said is how much better they feel on it, how delighted that they are to be off of ERT. So now we have 14 patients off of ERT and the four that are remaining on ERT in the study have already booked when they're going to come off of the therapy. So this has enormous support from the patients and I think that is what is going to make it a very successful launch for the partner that can take it forward and make a difference.
Amy Pooler: And if I may add, we also have R-MAT and Prime, which are designations that really analogize an unmet medical need for Fabry. So the Fabri patients, even though they can have access to ERT, are not satisfied with the current medicine and standard-of-care.
Bill Chappell: Thank you so much.
Operator: Thank you very much. At this time, I'm showing no further questions, and I would now like to turn the call back to Louise Wilkie for closing remarks.
Louise Wilkie: Thank you very much and thanks to everyone for joining us on the call today. We look forward to speaking to you soon.
Operator: Thank you for your participation in today's conference. This does conclude the program and you may now disconnect. Thank you.
