Thanks, Ioana, and good afternoon, everyone. We appreciate you joining us on the call today. As you know, I currently am serving on an interim basis as the company's CFO. About several weeks ago, we initiated a nation-wide CFO search with an accomplished recruiting firm and we already are connected with some great candidates, so I'm hopeful we'll have that position filled soon, and we will update you accordingly. Before I provide the business update today and identify a few events you can look forward to, I typically like to start off with a few general comments about the biotech environment and in particular, where I see Lineage within the field of cell therapy. Along those lines, one notable and recent event was yet another non-cancer cell therapy company catching the attention of a much larger acquirer. In this case, I'm of course referring to the acquisition of ViaCyte by Vertex. Although many investors focus on the oncology side of cell therapy, and indeed that is where cell therapy has established its strongest foothold, additional success continues to occur among non-cancer cell therapy companies, such as through the acquisitions of Semma, BlueRock, and most recently ViaCyte. And I would also include the partnership which we struck with Roche and Genentech as another significant event for the field of cell transplant medicine, reflecting positively on both companies and especially compared to some of the setbacks we've seen with certain mesenchymal or undifferentiated cell therapy companies. And as this field matures and more and more clinical data are generated, it increasingly appears that cell transplants, when deployed in the right setting with the right delivery tools, have the potential to become an important new branch of medicine. For this reason and others, Lineage will continue to try and position ourselves as a leader in this space through the combination of internal and partnered product development efforts. Thinking next about where Lineage sits within this emerging and promising field as a business and as an investment, I believe we continue to be in an environment where companies with three key characteristics may be in a better position than others to create value in the coming months and years. Those three characteristics are one, having multiple years of cash; two, having deals with big pharma companies; and three, having diversification through a portfolio of assets, preferably clinical stage assets, because those typically offer shorter timelines to approval than do preclinical ones. And those three features; cash, validation and a pipeline are attributes of Lineage, which I believe put us in a strong position to attract shareholder interest in the months and years ahead, and I'd like to touch on each of them briefly today. Starting with cash, it is clear that the biotech industry continues to be in a period of uncertainty and volatility. And for this reason, we have persisted with our disciplined use of capital. As of the end of the second quarter, we had a projected cash runway of at least two years. I will add that those two years do not include any cash milestones from the Roche agreement, which we may receive during that period. This runway also does not include any revenues from business development deals, although we are putting greater efforts behind that area as well. As noted in today's press release, we expanded one of our existing agreements last quarter and have initiated multiple discussions for additional corporate alliances, which might help fund or otherwise enhance our assets. And as you know, we continue to be in close contact with CIRM and intend to seek grant support for the OPC1 program. We may consider CIRM support for other programs as well. So as I have said before and can reiterate again today, we believe Lineage continues to be in a period of good financial health, which allows us to focus on creating value across the spectrum of short, medium, and most importantly, long-term timeframes. With respect to the second attribute, validation from big pharma, everyone by now is aware of the alliance we entered into with Roche and Genentech last year for the development of OpRegen for dry AMD with GA, or as it is now called by Roche RG6501. Although we're not able to share specifics, we're extremely pleased with the progress on our OpRegen development since entering our collaboration with Roche and Genentech and the resources which had been allocated to its furtherance. Most of the details are internal to the two companies, but I am able to say that during the second quarter, we made progress across all of the primary functional areas, including clinical, regulatory and manufacturing technology transfer activities, which are reflected in the additional $4.1 million of revenue recognized in the second quarter. Lineage successfully completed additional manufacturing runs of OpRegen, along with their associated CMC activities. We continued with the planned technology transfer activities and held a series of joint advisory and separately joint manufacturing committee meetings, which are collaborative forums for discussion and planning for the next steps for OpRegen and its related activities. Long-term follow up of patients from the Phase 1/2a clinical study which Lineage conducted is also ongoing. And most notably, those enrolled patients are still doing well which supports the multiyear durability of a treatment effect with OpRegen. Bolstered by the compelling body of data which we generated from OpRegen in early clinical trial, we will continue to work closely with the teams at Roche and Genentech to offer our support and experience, and advance OpRegen ever closer to later stage trials. We believe the results we have observed to date with OpRegen compare favorably against the various efforts focused on complement inhibition, which require a lifetime of frequent dosing, offer only a modest effect on GA progression, and to our knowledge have no or a minimal effect or benefit on visual acuity. For these reasons and many others, we're excited about generating further clinical data from this program as soon as possible. And thirdly, with respect to the diversification which are promising in recently expanded pipeline offers to investors, the team made excellent progress in multiple areas with a particular focus on advancing certain clinical and regulatory steps, which are not only necessary to support any future trials but also reduce risk across our portfolio. In particular, efforts were made to prepare for regulatory interactions for both, our OPC1 and VAC2 programs, which are necessary to support their next phases of clinical testing in spinal cord injury and oncology, respectively. And we also continue to engage in manufacturing and preclinical activities for our newly launched cell transplant programs for hearing loss and vision disorders. I'll add that activities which will support our regulatory interactions for OPC1 are nearing completion, which I believe is a positive reflection of our efforts to reduce cell therapy development timelines. Our new thaw-and-inject formulation of OPC1, which we manufactured via an improved and larger scale process, has been undergoing preclinical testing. And I'm pleased to share today for the first time that our OPC1 cells from the improved formulation and process have successfully demonstrated functional recovery in a clinically relevant animal model for spinal cord injury, including improvement in gait coordination and motor performance, along with cell engraftment, which manifests as a reduction of the area of cavitation in the spinal cord. These findings are consistent with prior data generated from a less efficient and lower scale manufacturing process. So we are delighted that our new and improved process has performed as intended in these studies. We expect that these results will be submitted and available for publication and review. In conjunction with our efforts on the other cell side, we have been working on an improved delivery system for OPC1. We believe the novel delivery system, which we licensed from Neurgain, will offer a safer and easier to use method for delivering OPC1, and I'm able to share today that most of the verification and validation activities for this delivery system, including its preclinical testing and support of a regulatory submission, have been completed, which moves us closer to our goal of filing an IND amendment and testing the DFT clinically. With both the cell and delivery activities making excellent progress this past quarter, we have reengaged with the California Institute of Regenerative Medicine, or CIRM, to open discussions about providing some financial support for this trial. We also have been reengaging with various industry and caregiver groups, such as Spinal Cord Outcomes Partnership Endeavor and American Spinal Injury Association as well as with the contemporary thought leadership in spinal cord injuries and with prior study participants. Everything seems to be coming together nicely for the OPC1 program, which I will remind you will include for the first time administering OPC1 to patients with chronic spinal cord injuries, not just subacute injuries, in our planned clinical trial to evaluate the safety and performance of the novel delivery device. As OPC1 gets increasingly closer to returning to clinical testing, it's worth remembering why we are so excited to continue this program. Now I won't repeat my usual comments about the enormous unmet medical need or the absence of any approved treatments, but refer you instead to prior clinical data. The full study results from the 25 patients enrolled in the Phase 1/2a clinical study in subacute cervical spinal cord injury were recently published in the Journal of Neurosurgery: Spine. In that publication, it was reported that OPC1 demonstrated an excellent safety profile. And at one-year post treatment, 96% of patients had recovered one or more levels of neurological function on at least one side of their body compared to an expected control rate of approximately 68% according to . In addition, 32% of patients in that study recovered two or more levels of neurological function on at least one side of their body, which again is higher than what would have anticipated. For these reasons and because there were many lessons learned from the initial trial of OPC1 which we aim to incorporate into the next study, we're very excited to put OPC1 back into clinical testing and evaluate the potential for our replace and restore technology to provide outsized clinical outcomes in spinal cord injury, not unlike our experience to date with the restoration of retinal tissue observed with OpRegen in the setting of dry AMD. Moving next to our VAC2 program, we have similarly continued to make progress toward an IND submission in preparation for potential U.S. clinical testing next year. I'd like to remind everyone first that Cancer Research UK continues to follow patients in the Phase 1 clinical study of VAC2 in non-small cell lung cancer, and the public release of clinical study results is entirely subject to their discretion and control. However, our team has received all the necessary clinical information which is required to support the regulatory interactions which we are working toward in the U.S. Depending on the outcome from those FDA interactions, we will be permitted to conduct clinical testing of VAC2 at U.S. centers for the first time. As we work toward those FDA interactions, I can update you today to share that following technology transfer of the VAC2 program from Cancer Research UK to Lineage, the Lineage team engaged in efforts to optimize the manufacturing process. The manufacturing team was able to successfully increase the production scale to a level compatible with early stage testing, while also significantly reducing our cost of goods. I will add that part of the reduction in the cost of goods was due to scale, but a large amount of that reduction was attributable to new methods of production, which we deployed. The team also made market improvements in the purity and functionality of the product candidate reflected in surface marker expression and in vitro functionality tests. I want to diverge for just a moment to highlight something which I think has gone under the radar for some time. These manufacturing achievements, which I'm describing today, reflect the third time for which Lineage's manufacturing team was able to meet ambitious production goals, goals which were unattainable by multiple prior sponsors and contract manufacturers. Manufacturing specific cell populations in a reproducible and consistent manner is extremely difficult. And in doing so using a process that can not only support initial clinical testing, but also have a line of sight onto a commercial platform is something we've done twice; first with OpRegen, then again with OPC1 and now we've nearly accomplished it a third time with our dendritic cell program. I don't think we get full credit for our manufacturing capabilities today. But I do think awareness is rising about how the manufacturing portion of cell therapy product development is so critical, and how doing it well can greatly reduce development cycles and avoid regulatory delays, the likes of which we have seen at some other companies. But I also believe that with additional time and success, the capabilities and knowhow of the Lineage manufacturing team will be more fully appreciated. Returning back to our pipeline programs, I'll conclude by adding that we also have continued to advance our auditory neuron and photoreceptor programs. They both are proceeding through the required preclinical development manufacturing activities which are necessary to support initial clinical testing. And as we generate data or have other interesting events, which we can share with you, you can expect updates from time to time on those two programs. Overall, our efforts at this time remain focused on conducting our share of the OpRegen development activities as well as successfully completing a diverse set of regulatory preclinical and clinical events for our pipeline, events which will provide not only clarity on our development timelines but also help de-risk and increase the value of our various assets. And because we're doing this work among the tailwinds of multiple years of cash, a big pharma partnership, and a diverse set of unique yet related cell therapy assets, I'm encouraged by what the future may hold for Lineage. A handful of specific goals and objectives which I'd like to invite you to be aware of include a planned interaction with the FDA in Q4, where we intend to discuss our OPC1 IND amendment submission to enable the clinical performance and safety testing of the novel delivery system in acute and chronic spinal cord injury patients. Second, a pre-IND regulatory interaction with the FDA also in Q4 to seek feedback on VAC2 CMC, nonclinical and clinical package to support U.S. clinical development. Third, evaluation of new partnership opportunities and/or expansion of existing collaborations. You saw recently that we are successful in expanding an existing collaboration with ABM for our high stem technology and that we continue to work with our partner, Immunomic Therapeutics, but we also would like to enter into additional alliances with larger economic benefits to Lineage and are aggressively seeking to identify opportunities to enter into such corporate alliances and help advance our assets. Fourth, we intend to submit a grant application to CIRM for the continued support of the clinical development of OPC1. And fifth, we intend to generate preclinical data to support a pre-IND meeting with the FDA for our new auditory neuron program. We, of course, have other goals, but the ones I've highlighted today in particular will provide additional regulatory and spending clarity and potential de-risking of our programs. We believe that execution of these goals will continue to demonstrate our ability to successfully advance novel cell therapy product candidates. Okay, with that, let me put on my interim CFO hat and turn next to our financial results. With respect to our balance sheet, we continue to be in a comfortable position as we expect to have more than two years of liquidity not accounting for any of the Roche and Genentech milestones, which we may receive in the next two years, nor for any business development or grant revenues which we may receive. Our reported cash, cash equivalents and marketable securities as of Q2 totaled approximately $72 million. In comparison, our normalized net operational spending for the past two years was between $20 million and $25 million. So even though we likely will see that amount be closer to $30 million this year, we have more than double that amount in the bank and can continue to just focus on running the business. Total revenues for the second quarter were approximately $4.6 million, an increase of $4 million, representing an increase of over 700% compared to the same period in 2021. The increase was due primarily to licensing fees in connection with the Roche collaboration agreement and reflecting our share of collaboration responsibilities. The largest portion of the activity attributed to this revenue was OpRegen manufacturing costs, but also included personnel, materials and clinical consulting expenses. As you may recall, we received the $50 million upfront payment from Roche in January on a cash basis. But on a GAAP basis, we are recognizing that $50 million over time, as opposed to a point in time, and utilizing an input method of cost incurred over total estimated costs to complete our performance obligations. The accounting recognition for the Roche upfront payment generally resembles a percent complete methodology, but is a reflection of our proportional contribution and may vary from quarter-to-quarter. Overall, our revenue recognition for the second quarter was largely in line with our expectations. Total operating expenses for the second quarter were approximately $8.6 million, an increase of approximately $1.1 million compared to the same period in 2021. The increase was a result of increased R&D spending of approximately $400,000 primarily related to development activities in our new auditory neuron and photoreceptor cell therapy programs, as well as an increase in OpRegen-related expenses to support the Roche collaboration. Furthermore, G&A expenses were up by approximately $700,000, mostly related to higher stock-based compensation and payroll and related benefits expense. Our loss from operations for the second quarter was approximately $4.2 million, a decrease of $2 million compared to the same period in 2021, resulting from the aforementioned $4 million increase in revenues and offset with a $1.1 million increase in operating expenses. The net loss attributable to Lineage for the second quarter was $6.8 million, or $0.04 per share. And as we always say at this point in the call, it's important to remember that the variance between our loss from operations and our overall net loss is impacted by changes in the value of our investments as well as by foreign currency exchange rate fluctuations related to our international subsidiaries. While these non-operational fluctuations are important, we tend to utilize loss from operations as a more relevant measurement with regard to our clinical programs. Turning to the balance sheet. We reported cash and cash equivalents and marketable securities of approximately 72 million as of quarter end. And additionally, as disclosed as a subsequent event in our recently filed 10-Q, during July, we also received approximately $0.9 million in net proceeds from a warrant exercise at our subsidiary in Israel. As I mentioned earlier, we anticipate a modest increase in our normalized net spending this year compared to the prior year, because our programs increased in number and continue to advance toward the next clinical trials. And we have certain performance obligations under the Roche agreement, such as supplying OpRegen cells for the next clinical trial. But as I also noted earlier, we estimate our net operational spend for 2022 on a normalized basis will be less than $30 million. Overall, we intend to maintain the same spending discipline that we have adhered to so far and which has served us well in the past. We believe that this spending discipline alongside our cash balance puts us in a good position to create value for shareholders from our investments. Our guiding principle at Lineage is to advance the emerging technology of cell transplant medicine and to show the potential for those transplants to outperform traditional approaches by providing the product attributes and rigorous clinical testing necessary to achieve commercially successful medicines in areas of high unmet need. To that end, we believe we have not only generated evocative data from our current clinical programs, but also have the opportunity to do so with our earlier stage initiatives. We've made significant investments in and improvements to areas such as production, scale, purity and delivery of our differentiated cells, which overall we believe is a proven path to creating best-in-class products for end users and strong competitive advantages to protect Lineage's and our current and potential partner sales over the long term. We also are working hard to identify and execute on measures which can reduce cell therapy development timelines, which we believe is a new area of opportunity in this young field. Wrapping up, as I speak with you today, we are confident in our cash position, our corporate alliances and our diverse portfolio of assets from which we can seek to optimize an attractive mix of development partnerships and internally developed programs. There is a lot to like about where we are today and much to anticipate from us in the coming weeks, months, and years. We sincerely appreciate your support, as we continue to position Lineage to become a leader in cell therapy and cell transplant medicine. And with that, operator, we are ready to respond to any questions for research analysts, which may be incoming.
