Analyst · Goldman Sachs. Please go ahead. Your line is open
Thank you, Tryn. And thanks everyone for joining us today. It's my pleasure to provide an update on our business for the first quarter of 2023. Through the first quarter, we continue to allocate our resources to the execution of our long-term strategy, investing in building team's technology and infrastructure to create the industry's preferred engine for antibody therapeutics and using this engine with partners to develop a diversified portfolio of stakes in future antibody therapies. This is a long-term strategy designed to create an increasing competitive advantage, to maximize value creation, and to mitigate the risk that is inherent in drug development. We continue to make progress on both objectives of our strategy. With respect to our engine at the front end from program launch to the candidate generation, I believe we now have capabilities that are unmatched in the industry, and that continue to improve. At the middle of our engine over the past 12 months, we have brought online a set of powerful new technologies and workflows for antibody engineering, high throughput assessment of drug like properties, and lead optimization. These capabilities are now being deployed in partnered and pre-partnered programs, and enable us to move programs quickly from idea right through to final drug candidate. A major focus is now on building the backend of our platform, including drug manufacturing, and regulatory capabilities. We're making good progress in recruiting the leadership to these efforts, and are actively building the labs and facilities that are needed for these functions. I'm confident we are on track and believe these efforts will prove highly valuable to our partners and will provide AbCellera a major strategic advantage to all dimensions of our business. Underpinning our workflows, we continue to invest in the automation and software systems that are critical to integration, efficiency and scale, and that are the foundation for the development and deployment of machine learning methods. In terms of building our portfolio, we continue to prioritize programs that maximize long-term shareholder value and not near-term cash flow or volume of partnerships. With the technology, the teams and the infrastructure in place, perhaps the most valuable input for adding value to our portfolio are the new ideas for medicines. We believe that good ideas can come from anywhere, where the large majority of our programs ideas come from our partners. Our partners come to us because we can help them get to their next value inflection point with greater certainty, speed and capital efficiency. Depending on the resources and program requirements, these collaborations contribute to programs -- contribute programs to our portfolio that can be structured with different risk reward profiles, including partner initiated discovery programs and co development programs, another rich source of problem ideas or antibody development problems that are widely known in the industry, but that are generally believed to be unsolvable. We invest in sustained technology development efforts that seek to unlock these high value opportunities. This requires working on multiple targets. As this work proceeds, these pre partnering programs can generate wholly owned assets that anticipate partner needs. Although these programs represent a small fraction of our portfolio, they have the potential to create the most value on a program by program basis when partnered. Moreover, success in our pre partnered work will demonstrate that our strategy is working and that our technology can open up new market opportunities, thereby attracting more program ideas from partners. Regardless of the source of the idea, and regardless of the program type, all programs are ultimately handed to partners. Each contributes to building a large portfolio that is diversified across partners, risk reward profiles, modalities and indications. Being open to working on the best possible ideas regardless of the source allows our engine to create maximum value for shareholders, partners and patients. T cell engagers or TCEs provide a specific example of how our pre partnering programs arrived from technology have done the development work that has the potential to open up new areas and make us a preferred partner for an entire class. TCEs are amongst the most promising new modalities in cancer therapy. First proven effective in liquid tumors, recent clinical data supports the potential of TCEs in treating a wide array of solid tumor types. T cell engagers are antibodies with two arms that are designed to simultaneously bind to cancer cells and specific immune cells called T cells. TCEs work by bringing T cells and cancer cells together and stimulating the T cells to kill the cancer cells. Two key challenges, both associated with toxic side effects must be overcome to realize the full potential of TCEs in treating cancer. The first challenge is to achieve the appropriate strength of T cell activation. Activation that is too low results in poor efficacy. While over stimulating T cells can result in cytokine release syndrome, a systemic inflammatory response that can limit treatment and result in severe or life threatening toxicity. The second challenge with TCEs is specificity that is to generate antibodies that recognize targets that are present only on cancer cells and that are not present on healthy cells. In April, AbCellera represented two posters at the 2023 American Association for Cancer Research meeting that demonstrates how our TCE platform can address both of these challenges. Today, I would like to highlight the main findings from this work. With respect to the first challenge, that of controlling the level of T cell activation. The level of activation is determined by the by specific format, as well as the properties and pairing of the source antibodies. The vast majority of TCEs activate T cells by binding to a protein called CD3. Because CD3 is a notoriously difficult target, there are very few accessible CD3 antibodies from which to make by specifics. This limits the ability to control the level of T cell activation. In fact, approximately three quarters of TCEs in the clinic are derived from a single most CD3 antibody, SP34-2, there was discovered in the 1980s and has sub optimal properties, including the induction of strong cytokine release. To solve this challenge, we launched a technology development project about 18 months ago to build a platform that could quickly generate TCEs that achieved the optimal balance between tumor cell killing and cytokine release. Our hypothesis was that there is no single CD3 that is well suited for every application. And that a large and diverse panel of CD3s is an essential resource for creating TCEs with superior properties. One of our posters that at ACR demonstrated data on our newly generated CD3 panel and its use in building optimized TCEs against to cancer targets EGFR and PSMA. Key results from this poster as are as follows. First, we have built what we believe to be by far the industry's largest collection of CD3 binders with more than 500 unique antibodies. This panel offers unmatched diversity of binding properties and binding locations, excellent developability and is highly differentiated from commonly used molecules. Second, this panel allowed us to effectively control T-cell activation against both targets and to achieve the desired profile of potent tumor self-killing with low cytokine release. Third, in all cases, the resulting TCEs had superior properties as compared to those built with a commonly used SP34-2 CD3 binder. And fourth, that the performance of different TCEs depends on the tumor target and the level of target expression on the cancer cells. Together these results support our hypothesis and demonstrate the potential of our platform to quickly generate TCEs that are engineered to have optimal properties. In our second poster, we presented an approach to addressing the second challenge of finding antibodies that are highly specific to cancer cells. Central to this challenge is that there are few known proteins that are expressed only on the surface of cancer cells and not on the surface of healthy cells. Because there are many more cancer specific proteins expressed inside cancer cells, the ability to target deeds with antibodies would open up a huge number of potential targets. One way of doing this is to target fragments of cancer proteins known as peptides that are naturally presented at the surface of cancer cells by the major histocompatibility complex or MHC. This process of peptide presentation by MHC is a part of natural immune surveillance and occurs in all cell types in the body. The potential of targeting cancer through MHC peptides has attracted high interest, and he's been pursued with different approaches, most commonly with cell therapies or engineered T-cell receptors, it's for called TCRs. An alternative approach is to use antibodies known as TCR mimetics that are highly specific to MHC peptide complexes. Discovering such antibodies is extremely challenging, and to date, there are only two examples that have made it into clinical development. Our poster demonstrated that we can quickly generate antibodies against a well validated cancer specific MHC peptide target derived from the protein MAGE-A4, for which there has been a clinical stage TCR mimetic. We screened more than a million cells and found more than a dozen fully human antibodies with high affinity, good development ability and specificity to MAGE-A4 that is comparable or superior to the clinical benchmark. Perhaps most significant is the speed and ease with which this result was obtained from a single screening campaign and without the need for subsequent antibody engineering. This result shows that we have capabilities that can readily address a large and essentially untouched class of tumor targets for TCEs. Importantly, TCR mimetic antibodies can also be used in other therapeutic modalities, including antibody drug conjugates, radio, pharmaceuticals and cell therapy. As such, we believe this is a technological advance that has broad implications for precision oncology. Another area, we are focused on is unlocking difficult membrane protein targets. I'm pleased to share that we have a new molecule enter the clinic this quarter against this challenging target class. This program is from one of the AbCellera's first discovery partnership agreements with Teva Pharmaceuticals and is directed against a difficult membrane protein target for an undisclosed indication. I would like to congratulate Teva on this milestone, and we are pleased to see the work from this collaboration progressing forward to help patients. As I've mentioned on previous calls, AbCellera's discovery engine and business model can also help to expand the ecosystem of drug developers by leveling the playing field for innovative new ventures. Again, this is about finding the best ideas and the best innovators and connecting them with technology to create new opportunities, and in some cases, new companies that might not otherwise be possible. This quarter, we are pleased to congratulate our partner Abdera who announced last month a $142 million financing. Abdera's proprietary technology develops next generation radiopharmaceuticals to treat cancer. AbCellera was a founding partner in Abdera and we started our first program with them in March of 2021. Abdera has announced that they have elected the first clinical candidate from this program, radio pharmaceutical for the treatment of cancer. The Company plans to file an IND in 2024. It's worth emphasizing the remarkable speed by which this company has gone from concept to high growth biotech with their first clinical candidate, a growing pipeline and backing by top tier investors. Finishing up, AbCellera is now in a position of enviable strength. We have a strong balance sheet and remain focused on the fundamentals of our long-term strategy. Accordingly, we are directing our energy and capital to three key activities. First, expanding the capabilities of our discovery engine, including forward integration with manufacturing, regulatory and clinical capabilities, continuing our technology development efforts to unlock new target classes and modalities, including T cell engagers, GPCRs, and ion channels, and advancing high quality programs and partnerships to build our portfolio. We believe continuous work and progress against these priorities will create the maximum long-term value while minimizing risks. This quarter, we have brought evidence the strategy is working in the form of a new molecule in the clinic, the cofounding and financing of an exciting new company in the area of radiopharmaceuticals and data showing that our engine can solve key problems in developing new T cell engagers for the treatment of cancer. We look forward to sharing more evidence of progress later this year, with anticipated milestones including election of the first clinical candidate from partner initiated co-development and pre-partnered programs. And with that, I will hand it over to AbCellera to discuss our financials -- pardon me, I will hand it over to Andrew to discuss our financials. Andrew?
