Thanks John. And thanks to all for joining us on the call today to discuss our third quarter corporate update. In addition to John, I'm joined by Andrew de Guttadauro, our Global Head of Business Developments and Mr. Kirk Look, our Chief Financial Officer. As I begin today's call, I would like to stress yet again, how thoroughly impressed I've been by the talent and the unwavering commitment of Oncolytics employees, their partners and investigators, as they continue to operate amongst on an industry wide challenges posed by the COVID-19 pandemic. Through the continued execution of our business continuity plan we've built on the positive momentum generated earlier this year to achieve three clinical milestones since our last update. These milestones have further validated our unique Oncolytics immunotherapy platform to advance our lead breast cancer program towards the initiation of a registration study that offers an opportunity to expand pelareorep's potential market into additional indications with high unmet needs. We believe we are well positioned to continue reporting a steady cadence of value creating milestones across our broad clinical pipeline. Now, I'd like to move on and discuss some of our recent highlights. Our primary focus is the advancement of pelareorep, intravenously delivered immuno-oncolytic virus towards a registration study in hormone-receptor positive HER2 metastatic breast cancer. We believe pelareorep can address a critical unmet need in this indication, as many currently available therapies are simply unable to produce a meaningful survival advantage for a significant percentage of patients. Such a belief is supported by the promising results of our Phase II study IND-213, which showed a near doubling of overall survival with pelareorep HR positive HER2 negative metastatic breast cancer patients. We continue to build on these results with our ongoing AWARE-1 and BRACELET-1 clinical trials, the completion of which…

Thanks Matt. As we've mentioned in the past, there's a growing interest from large pharma and biotech companies in improving the efficacy of checkpoint inhibitors, by pairing them with oncolytic viruses. This has been marked by several deals by companies such as Merck, BMS, and J&J, which have typically been preceded by initial collaborations designed to evaluate the feasibility of potential combinations. This is the exact approach Oncolytics has been taking. We've leveraged our robust and growing clinical data set to foster relationships with large pharma and biotech, which have led to our ongoing pelareorep studies designed to evaluate potential synergies with Roche's Tecentriq, Pfizer and Merck KGaAs BAVENCIO, BMSs Opdivo and Incyte's retifanlimab. The latest example of our ability to execute on this approach comes from the recently announced GOBLET trial, which is a Phase I/II trial been conducted in collaboration with Roche and AIO a leading academic cooperative medical oncology Group based in Germany. GOBLET is designed to evaluate pelareorep in combination with Rosche's anti-PD-L1 checkpoint inhibitor Tecentriq in patients with metastatic pancreatic, metastatic colorectal and advanced anal cancers. The study aims to address a large unmet need similar to the one being addressed by the IRENE study Matt mentioned earlier. There are approximately 4.8 million global GI cancer cases annually and approximately 80% of GI cancer patients do not respond to checkpoint inhibitor therapy, often due to immunosuppressive tumor microenvironment. These limitations of checkpoint inhibitors, combined with pelareorep's promising early clinical data set in colorectal and pancreatic cancer, highlight a compelling market opportunity for pelareorep in GI malignancies. Prior clinical studies have shown rapid maturation of dendritic cells, increased activation of CDA positive cells and upregulation of tumor PD-L1 expression following pelareorep treatment in GI cancer patients. These data highlight pelareorep's potential to increase the number of…

Thanks Andrew and good afternoon everyone. I'm very pleased to report that Oncolytics remains in a strong financial position as we advanced pelareorep towards registration. Now, our cash and cash equivalents as of September 30, 2020 were $26.7 million compared to 12.3 million as of September 30, 2019. This includes gross proceeds of 3.6 million from our aftermarket facility, which we established last quarter, pushing our financial runway to the end of 2021. Now, our operating expenses for the third quarter of 2020 were $2.5 million, compared to 1.8 million in the third quarter of 2019. This change is largely due to an increase in our Investor Relations activities, along with an increase in our Directors and Officers insurance premiums. Now, our research and development expenses for the third quarter of 2020 were $3.9 million compared to 1.7 million for the same period last year. During the current quarter, in addition to progressing our AWARE-1 and BRACELET-1 studies, we also completed a cGMP production run along with the associated release testing. We also incurred costs connected to changes in personnel and expansion of our US office, all in the support of our clinical program. Finally, our net loss for the third quarter of 2020 was $6.7 million, compared to 3.5 million in the third quarter of 2019, equating to a net loss of $0.16 per share for both the 2020 and 2019 periods. With that, I'll hand it back to Matt.

Thank you, Kirk. Now before we move to the Q&A, I wanted to talk briefly about a recent corporate achievement that we're pretty excited about. Last month we announced that Dr. Richard Vile, a world-renowned expert and key opinion leader in oncolytic viruses and adoptive T cell therapies join our Scientific Advisory Board. Dr. Vile is a professor of immunology at the Mayo Clinic, Director of Mayo's Immuno-oncology and Gene Virus Therapy programs and Co-Director of the Cancer Immunology and Immunotherapy program. His research specializes in oncolytic viruses, but also adoptive T cell therapies such as CAR T cells, and the potential synergistic interactions between these oncolytic viruses and adoptive cell therapies. Dr. Vile's extensive experience studying pelareorep has let him intimately familiar with pelareorep's substantially competitive advantage over other oncolytic viruses. One such advantage is pelareorep's ability to be administered systemically by nursing staff without the need for special handling procedures. This differs from other oncolytic viruses that often require intratumoral administration and or special handling due to the BSL-3 classification. Further, pela's systemic administration route facilitates its delivery and select for application in both local and metastatic tumors, and it remains the only viral agent to show a survival advantage in late stage metastatic breast cancer patients. These characteristics together with the guidance of Dr. Vile and the rest of our leadership team leaves us well positioned as we work to demonstrate the ability of pelareorep to synergistically combine with additional immunotherapeutic agents and increase the number of patients responding to such therapies. Looking ahead, we expect to continue achieving a steady cadence of value creating milestones through the sustained advancement of our diverse clinical pipeline. We continue to steadily progress towards a registrational study in our lead hormone receptor positive HER2 negative metastatic breast cancer program, while simultaneously executing on additional studies that broaden pelareorep's commercial opportunity. This execution in turn drives the continued development of our industry partners, which deliver additional value to our stakeholders. Our ability to consistently execute on our goals despite the unpredictable and industry wide challenges posed by COVID-19 speaks to the extraordinarily dedicated and talent of our employees and partners. I'm confident that we will continue to build on this positive momentum as we generate value for our shareholders and most importantly, improve the lives of our patients. With that, I'd now like to open the line to take some questions. Operator?

Certainly. [Operator Instructions] Your first question comes from the line of John Newman from Canaccord. Your line is open.

Hi, guys. Good evening. Thanks for taking my question. So I wondered if you could just remind us why showing increased T cell clonality with pelareorep in the AWARE-1 study is important and what it potentially indicates the therapy is doing especially in the absence of checkpoint inhibitors in cohort 1? Thanks.

Thanks. That's a great question. So my way of background CelTIL is a pathological assessment, so the patient will have a biopsy at baseline and appoint later. And really what CelTIL tells you is the level of cellularity or basically the number of cancer cells, as well as the number of inflammatory cells. So if we see a decrease in the cancer cells due to lice's or immune targeted at them, it goes - the cellularity decreases. And if we see an increase in inflammatory cells, it goes up in the net effect is you end up with a positive CelTIL score. What this really tells us in patients, especially notably in breast cancer, the presence - the absence of T cells, really is prognostic of a poor outcome. And really, what that tells you is there's no inflammatory cells, there's no NK cells, there's no T cells within the tumor, so the immune system is completely blind to this tumor, so these patients tend to have very poor prognosis. By increasing the CelTIL score and doing so, so dramatically in the vast majority of patients. What it tells us is the immune system now is aware of the tumor, it's trafficking these pro-inflammatory cells into the tumor to counter the growth of the tumor and also, we're getting a decrease in cellularity. So what that means is between the virus and the immune cells, it's eliminated in the cancer cells within the tumor. So the CelTIL score is a very positive tool and a very powerful tool to tell us how well the patients are doing. And what we're seeing from some of the early immunology and amino mass cytometry. We actually are getting expansion of T cells within the tumor, so T cells that were resident within the tumor, we're seeing those expand and presumptively, then those are anti-tumor T cells. The other thing that's coming out of the AWARE study is we could actually take the immune system at baseline, and again at day 21, when the surgery is done and we can apply that to the tumor of the patient. And what we find is there's no recognition of the tumor at baseline, and incredible rapid recognition by the release of chemokines or cytokines, notably interferon gamma that immune system has learned to recognize and target. And this is very important for these patients. Because what we want to establish, and I think we have established now in this cohort 1, we have memory cells that recognize the tumor that will be with these women for the rest of their life and hopefully are able to challenge micro metastatic disease and recurrence of disease so that these women have a much better long-term outcome.

Okay, great. And can you also talk about the differences that are seen when you think about what has been shown in the past with some of the PD-1 inhibitors showing an increase in CelTIL versus what you're seeing with pelareorep on its own showing an increase in CelTIL? Thanks.

We've presented previously in animal models, and I expect this to be the case, and the real meat of the AWARE study was cohort's 1 and 2. I mean, you can see this because it's reflective of the target patient population. But it's also the only cohorts that have 10 patients each, the rest of them have five or six. So the study was very much weighted to those cohorts. What we're seeing, as compared to what you would see with checkpoint inhibitors is, we're getting rapid expansion of T cell clones. Checkpoint inhibitors, with the exception of CTLA-4 really don't prime very much, they don't actually generate new clones, they just activate the existing ones. But what we've seen in early animal models, when we treat with reovirus we get pro-inflammatory cells. But we also get accumulation of some Tregs which are basically slowing or breaking the immune if you will, as well as MDSC cells, which have very similar role in promoting anti-inflammation. When we add checkpoint inhibitors to the tumor, what we find in animal models, at least, is we maintain that high level of inflammation with accumulation of CDA positive cells, but in the presence of the checkpoint inhibitor, we're negating or eliminating the Treg from the tumor, so we're getting a much more pro-inflammatory event. And what we're hoping is we'll see the same thing in human patients. What we'd like to see in cohort 2 is the same level of CelTIL, if not higher, but more the pro-inflammatory immune cells rather than that accumulation or Treg and early evidence would suggest that is the case.

Okay, great. Thank you.

Thanks for the question John.

[Operator Instructions] Your next question comes from the line of Wangzhi Li from Ladenburg. Your line is open.

Hi, thanks for taking my question. I also have a question about AWARE-1 data. Just what do you think any contribution from the letrozole in cohort 1 and 2? And also, I think maybe you mentioned, but what do you think you will - when do you think you will report data for the cohort 2, to is at San Antonio? Those are my questions. Thank you.

So to answer your second question first, yes, the plan for San Antonio is to really compare and contrast cohort 1 and 2, because I think that sets the stage for the registration study. I think it sets the stage for what we can expect coming out of the BRACELET study. So it will be an important presentation for us. And that's in San Antonio. We now have confirmed that we do have three presentations in San Antonio. And Wangzhi forgive me, what was your first question?

Do you think there is any role of the letrozole are the results that you've shown at the - in the recent presentation because both cohort 1, 2, also, the patient also had a letrozole, right, in addition to pelareorep?

We spoke with the investigators about that. In their previous investigations into CelTIL - like SOLTI Group is actually the group that defined and created the CelTIL score. So they're arguably the most familiar within the world, there's no assumption that letrozole is always going to have any effect in terms of creating a pro-inflammatory event. The reason it was included is this study - it's basically a new adjuvant study or a window of opportunity. So we're taking these healthy women, and they get standard of care, and then we add additional agents on top of that, because obviously, they're hoping to get some shrinkage or changes to their tumor, we do have to combine with standard of care, otherwise it would be unethical, but in speaking with the investigators in their own examinations with CelTIL, letrozole does not impact negatively or positively the CelTIL score in a meaningful way.

Got it, it's helpful. Last question is about BRACELET-1 study. Do you have any further color in terms of time for initial data report?

For, I'm sorry, Wangzhi, which study?

The BRACELET.

BRACELET is actually rolling really well. We anticipate the completion of enrollment first half of next year. So we'll be reporting, hopefully near final data by San Antonio next year. That means that we're hoping - we are hoping to get additional data readouts. But that's in conjunction with Pfizer our co-development partner, so they'll have to approve that.

Got it, thank you.

There are no further questions at this time. I now turn the call back to Mr. Matt Coffey for closing remarks.

Well, thanks again to everyone for joining us on the call. We look forward to the continued advancement of our clinical program and we'll keep everyone updated along the way. Thanks so much.

That concludes today's conference call. You may now disconnect.
