Thank you, Lisa. Good morning, everyone, and thank you for joining us this morning. I'm very excited about the progress we have made this quarter despite the challenges of the global pandemic as we work to develop transformative therapies with the potential to cure blindness diseases. Our first gene therapy product candidate, OCU400 for retinitis pigmentosa, is on track to enter the clinic with the two parallel phase I/II trials in the next year. Our second gene therapy product, OCU410 for dry age-related macular degeneration, and our first novel biologic, OCU200 for major retinal diseases, are on track to enter the clinic in 2022. Our business strategy of diversifying our product approaches to ensure portfolio diversification and reduce risk was shown to be prudent when in June, when we decided to discontinue the phase III trial of OCU300 for ocular graft versus host disease.
A pre-planned interim sample size analysis indicated the trial was unlikely to meet its co-primary endpoints upon completion. As a result, we ceased development of OCU300 and initiated a workforce reduction as a part of our shift in focus towards the modifier gene therapy platform and novel biologics program. We will add resources where needed in the coming year to further strengthen our R&D and clinical development groups in support of our planned short-term and mid-term goals of initiating four early-stage clinical trials within the next one to two years. We were successful in raising capital through our ATM programs to extend our runway into first quarter of 2021. We will continue to raise capital to support our short- and mid-term value creation goals for our patients as well as shareholders. Today, we will provide an update on our progress as we drive our product pipeline forward.
Sanjay will share highlights of our second quarter 2020 financial results before the Q&A. Our management team and advisors are dedicated to creating long-term value for our shareholders. As evidenced by the appointment of Dr. Mohamed Genead as chair of our Retina Scientific Advisory Board, we're attracting top talent to drive our product development initiatives forward. Dr. Genead is an ophthalmologist, retinal specialist, and inherited retinal disease expert. With over 20 years of experience in ophthalmology and gene and cell therapies. His deep experience in ophthalmology and gene therapy will be instrumental as we advance our breakthrough modifier gene therapy platform into the clinic next year. He's also offering tremendous support to Ocugen as an Acting Chief Medical Officer. We continue to be very excited about our modifier gene therapy platform, which has the potential to treat a variety of inherited retinal diseases with a single gene therapy product.
One of the biggest advantages of our modifier gene therapy platform is that it has the potential to eliminate the need for individual gene replacement and gene editing strategies, and may therefore, be highly differentiated from traditional gene therapy for eye diseases. Last month, we were granted our third FDA Orphan Drug Designation for OCU400 for the treatment of RHO mutation-associated retinal degenerative diseases. The RHO mutation is part of the retinitis pigmentosa group of rare genetic disorders that involve a breakdown and loss of cells in the retina and can lead to visual impairment and blindness. This is one of the more common mutations within the class, accounting for approximately 12% of retinitis pigmentosa patients in the United States.
Adding to the Orphan Drug Designations for OCU400 for NR2E3 and CEP290 mutation-associated retinal degeneration, the ODD for RHO gene mutation-associated retinal degeneration further supports Ocugen's breakthrough modifier gene therapy platform's potential to treat multiple blindness diseases with a single product. This week, we announced receipt of our fourth FDA Orphan Drug Designation for OCU400 in PDE6B, a gene mutation resulting in retinitis pigmentosa and autosomal dominant congenital stationary night blindness. Four Orphan designations for a single gene therapy product, OCU400, is distinct in the ophthalmology space, and we are excited about taking this program into clinic next year for patients who are in desperate need of rescue from blindness diseases. Inherited retinal degenerations such as retinitis pigmentosa affect over 1.5 million people worldwide. Over 150 gene mutations have been identified as associated with retinitis pigmentosa, and this number represents only 60% of the retinitis pigmentosa patient population.
The remaining 40% of these patients cannot be genetically diagnosed, make it difficult to develop individual treatments. We believe our modifier gene therapy has the potential to eliminate the need for developing more than 150 individual products and provide one treatment option for all these patients. This month, our Chief Scientific Officer, Dr. Rasappa Arumugham, will highlight our breakthrough modifier gene therapy platform as a part of the Next Generation Therapy Seminar at this year's World Orphan Drug Congress USA conference on August 24th. We will also be providing updates at the four investor conferences in the U.S. and the Gene Therapy Conference in Europe in September and October. Our strategic partnership with CanSino Biologics further solidifies our plans to enter the clinic in the next year for the development of OCU400.
Our manufacturing activities are going well and as planned, including scaling up to 200-liter batch size for our planned phase I/II trials. Our plan to scale up manufacturing to commercial levels at this time minimizes the risk for product inconsistency in future. Product consistency is extremely critical for any gene therapy product. We are on track with our IND-enabling GLP toxicology studies. Overall, we are very happy with the progress on this program and very excited to enter into the clinic next year as planned. For OCU200, we anticipate a pre-IND meeting with FDA later this year for this novel biologic for the treatment of major retinal diseases, including diabetic macular edema, diabetic retinopathy, and wet age-related macular degeneration. We're also planning to secure manufacturing partner soon.
For OCU410 to treat dry age-related macular degeneration, we are planning to meet with the FDA during the first half of next year to agree on roadmap for IND enabling studies and early-stage clinical trials. Before I turn the call over to Sanjay, I just want to mention our continued commitment to our shareholders as we drive the development of our product pipeline and our deep commitment to patients by addressing rare and underserved blindness diseases through gene therapies and novel biologics. I will now turn the call over to Sanjay to provide our second quarter 2020 financial update. Sanjay?
Thank you, Shankar, and good morning, everyone. As Shankar mentioned before, the second quarter has been a very eventful quarter for Ocugen and strengthens our mission to develop gene therapies to cure blindness diseases. I will now provide an overview of key financial results for the second quarter of this year. We ended the quarter on June 30th, 2020, with cash equivalents, and restricted cash totaling $15.1 million compared to $7.6 million as of year-end 2019. The increase in cash extends our runway well into the first quarter of 2021. In the second quarter of this year, we recorded revenues of $43,000 pursuant to a collaboration agreement with Adare Inc. with respect to the development of Adare's COVID-19 testing kits. At this time, we do not expect this agreement to be significant to Ocugen's overall business, but we will update the market as things develop.
Our research and development expenses for the three months ended June 30th, 2020, were $1.6 million, compared to $1.2 million for the three months ended June 30th, 2019. The increase was primarily due to severance-related costs, partially offset by the reimbursement pursuant to the collaboration agreement with Adare Inc. General and administrative expenses for the three months ended June 30th, 2020, were $1.8 million compared to $1.1 million for the three months ended June 30th, 2019. The difference was driven by the increase in public company insurance expense and severance-related costs. Net loss was $3.6 million, or $0.19 loss per share for the three months ended June 30, 2020, compared to a net loss of $3.5 million or $0.58 loss per share for the three months ended June 30, 2019. We ended the quarter with 135 million shares outstanding.
In April, we completed an amendment in exchange of the CDC warrants for 21.9 million shares of common stock and non-interest-bearing unsecured notes of $5.6 million. To date, the company has made prepayments of $3.1 million on the unsecured notes from proceeds received under the May 2020 and June 2020 ATMs. As a reminder, the warrant amendment and exchange helped address the overhang in our capital structure, and we currently do not have any of the pre-merger financing warrants outstanding. With that, we will open up the call for questions. Operator?
Ladies and gentlemen, to ask a question you will need to press star one on your telephone. To withdraw your question, press the pound key. Please stand by while we compile the Q&A roster. Again ladies and gentlemen that is star, then one to ask a question. Our first question comes from Keith Mackay with Chardan. Your line is now open.
Yes. Thank you. Two questions for you. First one, do you anticipate the publication of any additional preclinical data in any journals during the second half of the year?
Any additional data? Could you repeat the question, Keith?
Yes, publication of any preclinical data.
On OCU400?
Yes.
Yes.
Any of your gene modifier technologies.
Yeah. Good question, Keith. Currently, we're doing this year based on the agreement we reached with the FDA and the pre-IND meeting, we're executing our IND-enabling studies. We have started our GLP toxicology studies. Obviously, some of the work is getting done and the interim of any tox information will be available in the first half of next year.
Okay, great. To what extent is COVID impacting your ability to get that IND tox work done, the pre-IND tox work done?
Keith, I'm sorry. Your line is not very clear. Could you please repeat the question, please?
Sure. Can you hear me better now?
Yes. Better. Yes.
My question was to what extent is COVID-19 impacting your ability to complete the pre-IND tox work?
Actually, so far, we don't have any impact of the COVID-19. Our studies are ongoing as planned.
Okay. The fact that CanSino is busy developing their own SARS-CoV-2 vaccine, that's not impacting you on the manufacturing side at all?
It's a great question, Keith. They are on the forefront, and they're very busy. However, there's a strong commitment to our program. They're very excited to support us, and they're continuing to support us, including, as I mentioned just earlier, they're trying to scale up the process to 200-liter scale, which is a commercial scale, to minimize any risk on the CMC and manufacturing side. We have a complete support and cooperation from CanSino.
Okay. Well, very good. That's all I have.
Thank you.
Thank you, Keith.
Thank you. As a reminder, ladies and gentlemen, that is star then one to ask a question. Our next question comes from Swayampakula Ramakanth with H.C. Wainwright. Your line is now open.
Thank you. Good morning, Shankar and Sanjay. Can you hear me?
Yeah. Could you speak a little louder?
Sure. How about now? Is it better?
Yeah, it's fine. Yeah, thank you.
This is RK from H.C. Wainwright. A couple of quick questions. In general, regarding the retinitis pigmentosa patients, what % of these have the NR2E3 driven mutations? Are these mutations routinely identified, or do you need to do some kind of a diagnostic on these patients before you enroll them into your clinical trials?
Yeah. It's a good question, RK. On the prevalence rates, this is, again, it's about less than 1,000 patients in the U.S. All the clinical trials for this, we have to do the genotyping. I will also ask Dr. Genead, our acting CMO is on the call, to further address this. Dr. Genead?
Yes. Thank you, Shankar. To answer your question, we definitely need to genotype those patients prior to enrollment in all clinical trials. This is standard procedure being done right now in gene therapy trials, we're definitely very confident to do that with our clinical site investigators. They are trained to do that. This will be a part of the process. Regarding the prevalence, as Shankar mentioned, these are rare diseases, as you know, retinitis pigmentosa is one of the most common inherited retinal diseases and retinal degeneration. Still rare, it's not ultra-rare. Orphaning of disease is very common, as you saw the prevalence in our slide. Regarding the NR2E3, which is one of the mutation of the gene modifiers. This genetic mutation has different clinical phenotypes. This is only one.
One of them is retinitis pigmentosa, but there's other clinical disease implicated with this gene mutation. That's the whole notion about the OCU400 program that we apply in one product for multi retinal degenerated diseases. For your question, specific about RP or retinitis pigmentosa, this can take up around one, 2% of autosomal dominant retinitis pigmentosa.
Thank you very much for that, Dr. Genead. Is the genetic test currently available and validated, or do you need to do some work to get a validated test before applying that to your screening protocol?
This is Mohamed Genead.
Yes, sorry.
Yes. No, these are standard testing. The genetic testing for patient with inherited retinal diseases or genetic diseases have been done enough for years right now, close to 20+ years, even earlier, for systemic indication. You take blood samples, and you send it to a genetic lab, and they look at the mutations on the chromosomes according to which mutation. This is well established because the data has been done before. There's some commercial product in the eye for ocular gene therapy . We're using the same procedure, nothing different, than what had been used before in all the other insertive trials for genotyping.
Perfect. Then Shankar, in general, I know you're planning to get four programs up and running in the clinic over the next year and a half. In general, what would be the design of these phase I studies? Also, how should we think about the development plans for these four programs that you want to get going within the next 12 months or so?
Yeah. Good question, RK. I'll briefly explain high level, then Dr. Genead can add in. The gene therapy programs, as we outlined in our deck, we're planning to initiate two parallel phase I/II trials. Again, based on the guidance from the FDA and the agreement, these are going to be small. You're talking about nine patients in each trial with the three cohorts for a one-year study because you have to monitor the patient's safety for one year along with exploratory endpoints, then you're going to pick one of them to finalize and move into phase III. Then OCU200 and OCU410, again, these are targeting major retinal diseases, and the phase I/II programs will have, obviously, a lot more patients than OCU400. Mohamed, you want to add anything?
Yeah, absolutely. No, thank you, Shankar. A little more highlight. For the OCU400, which is using the gene modifier platform technology in-house, we're going to start with the first-in-human, which will be the safety, the multi-ascending dose trial. That's what the FDA and the health authority require, especially with a novel product. What has already been done ocular gene therapy space. It will be multi-ascending, will be at least three dose of low, mid, high dose of our OCU400 product, different concentration, obviously different genomic load. Then we will have independent data safety review to look at all those scores before we escalate. Then we will look as well as safety, look at the efficacy trends in those patients. We will look at two different mutations in the first study, or the two parallel studies will start in-human by next year with OCU400.
The first one will be for a patient with NR2E3 mutation, and the other one will be the rhodopsin, so RHO-associated mutation. That will be the first trial using the OCU400. Shifting to the OCU200, which is not another gene therapy, it is a novel biologic program in-house. We will be targeting the first indication for retina will be diabetic macular edema as our first lead indication with our novel biologic. We will start with the phase I/IIA. It will be around close to 50-patient trial. We will look at patients with diabetic macular edema, and we will look at our standard in efficacy endpoint safety, obviously going to be the main objective, but also we will look at other efficacy endpoint on the visual acuity and the retina thickness, which has been the standard endpoint for this patient population.
That will be the idea with the two major programs, the OCU400 and the OCU200. The OCU400 planning will be upcoming early in 2021, second 2022, excuse me.
Thank you. Thank you very much, Shankar and Sanjay. Talk to you soon.
Thank you, RK.
Thank you, RK.
Thank you. Our last question comes from Kristen Kluska with Cantor Fitzgerald. Your line is now open.
Hi, good morning, everybody. Hope you're all doing well. Maybe just a follow-up from one of RK's questions. Given the 400 pipeline focuses on patients with varied prevalent rates, what are you doing now to try to locate where some of these patients could be for the trial? Also, what are your broad thoughts on genetic testing efforts in general, given the marketing of LUXTURNA and also the increased number of clinical trials focusing on RP patients?
Dr. Genead, go ahead.
Yeah, absolutely. Thank you for your question. Great question. We definitely are planning now to build our patient registry. One of our plan is working now with the center of excellence in the country, not only in U.S., also in Europe. As you know, for this kind of patient, I'm a retina surgeon, so you see this patient in your general retina clinic, but it's more specialized. We have centers of excellence for retinal degeneration in this country. We are working now with our collaborator in the country and also elsewhere in Europe for finding these patients. They have the volume, they have their database, which we'll be partner with to identify those patients. We already did groundwork around that with our clinical trials and our potential investigators in our trials.
We will continue on that work as we go further our development. Regarding the genotyping on the strategy for late development and our commercial strategy, that will be one of the key things for our clinical development and even product development strategy. To find this patient in registry, and we're working now with the clinical scientist said earlier, the clinical research, and also with the patient advocacy group which we are very closely connected to, and going to work with other foundations for each disease we're targeting, like the Foundation Fighting Blindness and other foundations that have their own registry for those patients. Definitely one of the areas we're looking at very carefully, and we started the work, and we'll continue our work on that space.
Okay, great. Thank you very much.
Thank you, Kristen.
Thank you. Ladies and gentlemen, this concludes our question and answer session. I would now like to turn the call back over to Lisa DeScenza for any concluding remarks.
Thanks to everyone for taking the time to join the call this morning. We're dedicated to filling significant patient needs by bringing to market transformative therapies for blindness diseases. We look forward to providing further updates in the coming months. Thank you.
Thank you. Ladies and gentlemen, this concludes today's conference call. You may disconnect your lines at this time. Thank you for your participation, and have a wonderful day.
