Thank you Alex. And welcome everyone to ZIOPHARM 's third quarter 2021 earnings call. When I joined ZIOPHARM just over two months ago, I promise to be transparent with shareholders and share my observations and perspectives at the next opportunity. Today, I'd like to do that and highlight some of our recent accomplishments and lay out my vision for the next year. A month ago, we made the decision to strategically restructure the organization and focus our efforts on advancing our differentiated TCR-T cell platform. As a result, we took immediate action to right-size the organization with a focus on generating clinical data while maintaining a robust R&D discovery engine. I'm impressed by the quality, dedication, and resiliency of our team at ZIOPHARM, and I'm confident we possess the internal capabilities to advance our innovative scientific research into the clinic. We appreciate the importance of generating clinical data to validate our TCR-T platform, and are making excellent progress in that regard. We realized the fastest way to the clinic was not to rely on an external contract manufacturer, but to operationalize our in-house CGMP clinical production unit or CPU. I'm very proud to announce that we completed the necessary engineering and process qualification runs in October at our CPU. The ZIOPHARM team did an excellent job working together in across disciplinary manner to accomplish this important step. We remain committed to begin treating patients in the first half of 2022. Our TCR-T platform is predicated on a robust research and development lab and team based in Houston. The R&D team is working on several different programs. First, we continue to support the lead program, our TCR-T library trial, and are working to incorporate additional TCRs into this IND. Second, we are advancing the development of our membrane bound aisle 15…

Thank you Kevin. This past quarter, we have continued to make progress across all our manufacturing, development programs, and R&D activities. And like Kevin said, all of us at ZIOPHARM are committed to execution in generating clinical data in the next year. Let me start by highlighting the progress we have made that [inaudible 00:06:52] manufacturing facility in Houston, Texas. We have built and are opening our own?CGMP? clinical production unit CPU. Commissioning of the facility, as well as the safety process validation were completed in the second quarter and we recently completed engineering and process qualification of ramp in the CPU. We are committed to having a similar manufacturing capability operational to support the third patient dosing in the first half of 2022. Once operationalized, we expect to begin dosing patients in our Phase 1/2 TCR-T library study in the first half of 2022. As Kevin mentioned, our TCR -T library study is a basket trial that will evaluate patients across 6-solid tumor indications; lung, colorectal endometrial, pancreatic, ovarian and and bile duct cancers. Last month, we open our screening study at the MD Anderson Cancer Center, and we are actively screening patients that will be enrolled on the Phase 1-2 treatment study based on matching neo -antigen TCR actually bearing that are available in our TCR-T library. Patients with them being fuse with autologous T cells, that being engineered to express the service sectors using our Sleeping Beauty on Transco Sales Technology. And that are reactive against such [inaudible 00:08:27] neoantigen. The Phase 1 dose finding portion of the study will evaluate patients on one of 3 dose levels. We believe that our adaptive trial design is an optimal approach to advancing our TCR-T library forward, as it will allow us to rapidly and cost effectively, first identify…

Thank you Raffaele. For the third quarter of 2021, we reported a net loss of approximately $22.7 million or an $0.11 net loss per share compared to a net loss of approximately $20.3 million or a $0.10 net loss per share for the third quarter of 2020. Research and development expenses totaled approximately $14.5 million for the third quarter 2021, compared to approximately $14 million for the same period in 2020, an increase of 4%. General and administrative expenses we're approximately $8.2 million for the third quarter of 2021 compared to approximately $6.4 million for the third quarter of 2020. Total operating expenses for the third quarter of 2021 were approximately $22.7 million compared to approximately $20.3 million for the same period in 2020, an increase of 12%. Cash and cash equivalents, as of September 30, 2021, were approximately $91.7 million. Given our current development plans and continued cost management efforts, we anticipate our cash runway will extend into the second quarter of 2023. That concludes our financial statements. But before we open the call to questions, I'd like to close by saying that we are committed to building a leading TCR-T company. We have created an organization that is appropriately capitalized and staffed for success. Over the next year, we will remain focused on transforming the innovative scientific research we have developed into clinical progress. We have made excellent progress on operationalizing our in-house manufacturing facility, and with existing cash sufficient to fund our operations into the second quarter of 2023, we are confident in our ability to enter the clinic with our TCR-T library program and generate meaningful clinical data in 2022. With these clear and achievable strategic priorities in place, our entire team here at ZIOPHARM is focused on execution as we aim to bring value to our stakeholders and improve the lives of cancer patients. We will now open the call to questions. Hilary.

Thank you. At this time, we will be conducting a question-and-answer session. [Operator Instructions]. One moment, please, while we poll for questions. Our first question is from Alethia Young of Cantor Fitzgerald. Please proceed with your question.

Hi, this is Emily on for Alethis. Thanks for taking our questions. I'm just curious what the gating factors are to starting the phase 1 plus 2 study now that you've made the progress with the in-house manufacturing. And then, maybe also just comment on now that you've done the restructuring, how do you expect your operating expenses to change in the fourth quarter and maybe in 2022 as well? Thank you.

Great. Thanks, Emily. I'll start with the second one first. With regards to cash burn, we anticipate that our burn going forward will be less than $15 million a quarter. And so, that's something that we will be reporting on our cash burn going forward as well. And some of the cash is associated with repaying the term loan that was put in place as well as we look in the future horizon. And so, those terms of the term loan are spelled out into our 10-Q. But we do have a nice reduction in our cash band while remaining the appropriate size team to execute on our goals. Now, with regards to treating patients in our trial, it's important that we have the all-clear on our IND from the FDA. So the FDA review is probably the most important part to the next step along with screening and enrolling patients. Raffaele, anything you'd like to add to that?

Just as I said earlier, that we already started screening patients, actively screening patients. We are already screening patients, that will be our role when the Phase 1/2 treatment starts.

Okay Thank you.

Thanks Emily.

Our next question is from Arthur Hey, of H.C. Wainwright. Please proceed with your question.

Good afternoon everyone. This is Arthur Hey for [inaudible 00:15:34], thanks for taking my question. So I guess I just want to follow-up on the TCR-T trial. Could you give us more colors to see what else need to be complete or to be qualified before you guys studying to dose the first patient in that trial?

Raffaele, do you want to reiterate what we said before to Emily?

Exactly. We are waiting for the FDA review as Kevin mentioned earlier. And we are already screening patients that can be a roll on the trial. Now, you have to keep in mind that the frequency of the mutations and that duly Apple-type (ph). But we're selecting these patients and we're ready to start enrolling patients fairly soon, I would say, but in the first half of 2022.

Okay. Thank you. Thank you for that. And congratulations on the manufacturing part. I just want to know for those manufacturing part, it's most likely more for the clinical trial, or how about for the commercial manufacturing, what's your plan on that part? Thank you.

Yes. Thank you. For the clinical part, we have our manufacturing capabilities, on the commercial side, that's quite a number of years away from right now, and we have not communicated what our strategy will be at that point.

Okay. Sounds great. Thank you. Thank you for taking my question.

Thank you, Arthur.

Our next question is from Thomas Flaten of Lake Street Capital Markets. Please proceed with your question.

Good afternoon, guys. Thanks for taking the question. I was just curious following the restructuring that you had. Have there been any retention strategies put in place to keep the staff that's left behind? Have there been any other unforeseen departures? I'm just curious what the impact that has had on the remaining staff.

Thanks, Thoms. We did put in incentive stock option grant to make sure that we are all aligned with regards to creating value for our shareholders, and at the same time, motivating and incentivizing our team. And so, that has been well-received by the team, and everybody has been working very hard, very much aligned. And we have not had any resignations that come as a surprise. So we're very excited with the retention of our team. And as a core team, we're very strategic with who we ended up keeping. And I just reiterate the strength of the team that we have. The resiliency of the team, and the amount of effort and deliverables that are coming out of this team is quite impressive, and really well-positioned to get this clinical trial up and running and enrolling patients here in the first half of next year.

Thanks for that. And I apologize if I missed this, but with respect to the IND clearance, are you anticipating adding new TCRs to the IND prior to clearance or will that be an ongoing rolling exercise that you go through as you identify new TCRs?

Raffaele, why don't you speak to that.

Yes. So I wouldn't put a time line or time connection with the submission but we are planning adding TCR in a [inaudible 00:19:17] manner, not only for the 4 that I mentioned earlier, but additional TCR that will come in the next year.

Great. And then, finally --

I wouldn't link the thing together, though.

Got it. No, understood. And then just one final question. Any word out of the NCI on how things are going over there?

So I believe that Raffaele and team will be visiting the NCI later this week as part of the SITSI Visit, but we don't have any update right now to share with regards to the NCI.

Great. I appreciate taking the question. Thanks so much.

Thank you.

We have reached the end of the question-and-answer session. This concludes today's conference, and you may disconnect your lines at this time. Thank you for your participation, and have a great day.
