Cindy, I'll turn it over to you.
Thank you all for joining our annual shareholders meeting. I am pleased to present to you today. Pushing forward the boundaries of medicine entails risk as well as great promise. This slide tells you about the risk. At Editas, we strive to make differentiated transformational medicines for diseases of high unmet need.
To accomplish this objective, we are pursuing 2 strategic pillars in vivo CRISPR medicines and engineered cell medicines. With our in vivo CRISPR Medicine Portfolio, we are leveraging AAV delivery with our proprietary staff aureus Cas9 Envheim. To develop medicines for serious ocular diseases. We then plan to expand into neurological diseases in the near term, and other therapeutic areas further out. For our engineered cell medicines, we are developing best in class medicines, for hemoglobinopathies and cancers with our proprietary Cas12A enzyme.
Over the past few years, We have invested heavily in our platform and can now leverage this effort to advance both in vivo and engineered cell medicines. We have a strong IP portfolio and continue to advance our organizational capabilities. Based on this strategy, we are advancing a broad pipeline of medicines. You can see that our most advanced programs are edit 101 for LCA10, edit 301 for sickle cell disease, and beta thalassemia, and edit 201 to treat solid tumors. On the in vivo side, we are also advancing programs for additional ocular indications and expanding into neurological diseases.
In engineered cell medicines, In addition to EDIT-three zero one and EDIT-two zero one, we are making strong progress on our iPSC derived NK cell program. For solid tumors. Now let's turn to our in vivo portfolio, leveraging our unique capability to deliver CRISPR medicines using AAV. We are pioneering in vivo CRISPR medicines with EDIT-one hundred and one for patients with leber congenital amaurosis 10 or LCA 10. LCA 10 is an inherited form of blindness caused by a mutation in the gene that encodes the photoreceptors rapidly degenerate robbing young children of their site.
We hope to rescue vision in these by removing the genetic mutation to restore the Sept 290 protein and thereby rebuild the photoreceptors. Earlier this year, we became the 1st in history to treat a patient with an in vivo CRISPR medicine when we initiated dosing in the Brilliance clinical trial for LCA10. We aim to complete the adult low dose cohort and dose at least one patient in the adult mid dose cohort by year end, providing the potential for clinical data this year. The design of the Brilliance clinical trial is typical for a rare disease. This is an open label, dose as escalation study with primary endpoints assessing safety and tolerability and secondary endpoints, measuring efficacy.
We are starting in adult patients with light perception only and with a dose that is on the low end of the range where we expect therapeutic benefits. Based on safety and tolerability in these patients, we intend to escalate the dose in adults and then move into children who have some visual acuity. We are pleased that the study was cleared to continue following a review of safety data on Secondary efficacy endpoints include visual acuity, a mobility course, macular thickness, cupilometry, and electroretinogram. Our second ocular program, EDIT 102, is aimed at us2a, which, like LCA10, is an inherited retinal disease affecting the photoreceptors. As a result, edit 102 benefits tremendously from our work on edit 101.
In particular, we use the same vector, same Cas9, and same promoter as EDIT-one hundred and one. We believe this derisk and accelerates our path to the clinic and ultimately a transformative medicine for these patients. EDIT 102 is ready for IND enabling studies pending a decision from AbbVie on whether to license the program under our 2017 collaboration agreement with Allergan. We expect We leverage learnings for subsequent programs, thereby allowing us to create clinical molecules with increased efficiency. We now plan to leverage We are uniquely positioned to do so with our proprietary STAP OriA's Cas9 enzyme, which is small enough to be delivered with a single AAV for increased efficiency.
Beyond ocular, we are expanding into neurological diseases in the near term and additional therapeutic areas further out. For these reasons, we view in vivo CRISPR medicines as one of our 2 pillars of our therapeutic strategy. Now I would like to transition to engineered cell medicines, the 2nd pillar of our therapeutic strategy. Let's start with our editing of hemopoietic stem cells for beta hemoglobinopathies including sickle cell disease and beta thalassemia. These diseases are areas of high unmet need with a clear understanding of the underlying biology.
In particular, we know from human biology that elevated fetal hemoglobin can dramatically reduce the symptoms of these diseases. We recognize that this is a competitive field and believe our candidate at a 301 can be best in class, which I will discuss on the next slide. We remain on track to file the IND for sickle cell disease by the end of this year. This slide summarizes why we think EDIT-three zero one can be best in class. Starting at the top, we believe that EDIT-three zero one has the potential to impact beta globin in the best way.
In particular, preclinical data shows that we induced more fetal hemoglobin than BCL11A enhancer approach. And relative to lentiviral gene therapy, gene editing will reduce the sickle globin and therefore not have to compete for alpha globin in the same cell. On the safety side, editing at the globin locus, but not at the BCL11A locus is supported by human genetics. Our preclinical studies identify one potential concern for BCL11 a editing as we found, deleterious lineage skewing, when editing the BCL11A locus. Finally, gene editing is more specific than lentiviral expression.
To get the high levels of beta globin required for efficacy, there will be cells in the CD34 population that carry up to 20 copies of the viral genome. These random integration events have the potential to inadvertently activate or inactivate genes involved in tumor genesis. This slide includes results from our preclinical in vivo studies using blood from healthy human donors. As we had predicted from our in vitro studies, editing at the beta globin site with Cas12A caused a robust induction of fetal hemoglobin, exceeding 50% and approximately 45% above background. Encouragingly, fetal hemoglobin induction was pancellular as shown on the right.
Taken together, we believe that EDIT-three zero one has the potential to be a best in class medicine, and we are decided to progress to the IND stage this year. With this vision for the cell therapy space, there are several cell types that are system and have proven therapeutic for liquid tumors. These cells recognize tumors either with the endogenous, alpha beta T cell receptor, or synthetic chimeric antigen receptors or cars. While we can edit these cells to construct allogeneic medicines, The potential for graft versus host disease from residual contaminating cells remains a significant issue. Further, the number of edits required to make these cells allogeneic will consume much of the potential for genetic changes in these cells.
For these reasons, we are focusing our efforts on our wholly owned programs on innate immune cells, particularly natural killer or NK cells. NK cells can recognize tumors by a variety of mechanisms including multiple innate receptors that recognize cells that don't express T cell antigens and cells that express stress ligands. NK cells are also part of the mechanism by which many therapeutic antibodies kill tumor cells in a process known as antibody directed cellular cytotoxicity. Further, NK cells can be engineered with cars. And importantly, NK cells do not cause graft versus host disease.
We recently initiated IND enabling studies were EDIT-two zero one and allogeneic NKSL Medicine targeting solid tumors. Approximately 90% of all cancers are solid tumors. Edit 201 is the first of these medicines that we hope will extend and dramatically improve edited healthy donor derived NK cells will be a significant advance to the field. We believe that iPSC derived cells will unlock the full potential of cell medicines and some of the progress we have made. Starting we have partnered with Bluerock Therapeutics to both obtain GMP cell lines and transfer the knowledge of this process to Editas.
These cells must then be edited and characterized so that a clonal cell line can be selected. We have optimized editing conditions with our proprietary CAF12A derivatives. Further, we have built an unparalleled ability to characterize the genome of edited cells. We will then take these edited clonal lines and differentiate them to make IPS C derived NK cells using a proprietary and scalable process. The end result will be cells that are more highly engineered and as possible with other cell sources with a low cost of goods and available off the shelf in perpetuity.
On this slide, we show some of our early results with Ipsc derived NK cells. The left graph shows that we can efficiently edit a variety of genomic targets. The right graph shows that edited cells are more potent at killing tumor cells than unedited cells. Partnerships have been and will continue to be an important component of building our leadership position. We have 2 important development and commercialization partnerships, The first is with Allergan, now part of AbbVie, and ophthalmology.
The second is with Bristol Myers Squibb, to develop alpha beta T cell medicines for cancer and autoimmune diseases. We have also formed 3 important research collaborations enable and accelerate our pipeline. We have partnered with AskBio to access technology and capabilities that support development of an in vivo CRISPR medicine for neurological diseases. We have a non exclusive cross license in collaboration with Bluerock Therapeutics to access technology and GMP IPS cell lines to enable our IPS derived oncology program. And earlier this year, we signed a deal with Sandhill Therapeutics to access their proprietary Binance technology to develop healthy donor NK cell medicines for solid tumors.
We also underpin our business with a very strong intellectual property position. To close, we are making progress on both pillars of our therapeutic strategy to create differentiated transformational medicines for the diseases of high unmet needs using our proprietary GAP AUREA's CAF9 and CAF12A enzymes. For the in vivo medicines, we are advancing EDIT-one hundred and one. Earlier this year, we treated the first patient ever with an in vivo CRISPR gene editing medicine. In addition, the remainder of our ocular program is progressing nicely.
We are leveraging these efforts in ocular therapies to pursue additional therapeutic areas, starting with neurological diseases. For engineered cell medicines, our lead program is edit 301 for sickle cell disease and beta thalassemia. We continue to believe that EDIT-three zero one is a potentially best in class medicine. We have made significant progress in our Healthy donor NK cell medicine program, and we are excited to advance EDIT-two zero one for the treatment of solid tumors. In parallel with EDIT 201, we are also advancing programs using CRISPR editing for the potential treatment of both solid and liquid tumors, including engineered iPSC derived NK cells.
We remain incredibly excited about the times ahead, and I look forward to updating you on our future milestones. Thank you for
Hi, Cindy. We have, just a couple of questions. They are related to our edit 101 program, and, I will just summarize They're asking for, if you could provide any additional detail on potential for when data may be released to the public. As well as plans for, dosing additional patients, particularly around the adult low dose cohort.
Sure. Thank you. The dosing of the second patient, we hope to, occur in the near term, we have, as I mentioned, been cleared to, progress to the second patient based on the first patient safety data. It is dependent upon the reopening of our clinical sites under the current COVID situation, but we hope and expect that will be, very soon. Regarding the release of clinical data, we are not anticipating to release data on a patient by patient basis, but do hope to have data available later this year.
And, Obviously, if there's anything significant to report, we will, report that data, but we wanna make sure that we are appropriate appropriately reporting data and not necessarily on a patient by patient basis.
So at this time, I'm showing no further questions.
Okay. Well, thank you, everyone. We appreciate your time and attention, and have a great day.
Take care. Thank you.
