Welcome to the First Chemomab quarterly conference call covering 2021, fourth-quarter, and full-year, along with an update on our planned activities for 2022. I came on board as CEO this past September, after a careful review of the company's science. I was impressed by the clinical and commercial potential of CM-101, our pipeline in the product, focusing on indications that the confluence of inflammation and fibrogenesis, an area of great unmet medical needs. Also, by the rigorous translation on pre -clinical science produced by our Co-Founder and CSO, Dr. Adi Mor, and her team. Our lead clinical candidate, CM-101, is a monoclonal antibody that neutralizes CCL24, a unique target that has been validated in 11 pre -clinical model systems. CM-101 has demonstrated good safety and pharmacokinetics and pharmacodynamics in two Phase 1 studies in both healthy volunteers and patients, which further supports our belief that CM-101 has first-in-class potential in the two rare disease indications of primary sclerosing cholangitis or PSC. And systemic sclerosis SSc, as well as in an additional clinical indication. I'm excited to be Chemomab's CEO and now also Chairman. I believe the company has a very bright future and I look forward to sharing this progress with you. First, an overview of our progress in 2021, which was an eventful year for Chemomab. Key accomplishments included: in February, we announced positive results from a Phase 1b trial in patients with non-alcoholic fatty liver disease, reporting that CM-101 was observed to be safe and well-tolerated to fund multiple administrations. With evidenced for dose-dependent target engagement and positive changes in Fibrotic biomarkers. In March, Chemomab completed a merger transaction, listed it's ADRs on NASDAQ and close a $45.5 million pipe. As part of the merger and public listing, Chemomab expanded its Board of Directors adding industry-savvy directors with…

As Dale noted, the strategic review has resulted in a number of important changes to the CM-101 clinical development program. We initiated this review based on multiple relevant factors, most notably upon receipt of key feedback from global regulatory authorities. Today, I am presenting the broad outlines of the revised plan. We expect to provide significantly more detail in several months time. Key elements of the revised clinical program include implementing a dose finding component to the CM-101 development program by significantly expanding our phase two trial for primary sclerosing cholangitis. We're currently exploring the safety, tolerability, and importantly, the biomarker and clinical activity of 10 migs per kilogram of CM-101 administered intravenously every three weeks, over 15 weeks. We will be increasing the size of the study by adding additional dose cohorts, including plans to evaluate both a lower and a higher dose level of CM-101 in this ongoing trial. In addition, we plan to add an open-label extension to the trial to evaluate the safety, tolerability, and durability of effect, over longer treatment durations. Finally, we will be performing an interim analysis of the currently enrolling dose cohort in the study to assess safety in biomarker data, with an expected readout in the second half of this year. Regarding systemic sclerosis. Focus the goals of our systemic sclerosis trial, towards establishing biological and clinical proof-of-concept in this patient population. We are revising the design of our planned systemic sclerosis trial, in a way that should enable an expedited path to proof-of-concept data, as well as further elucidation of the different mechanisms of action of CM-101 in treating the skin long and vascular damage seen in systemic sclerosis patients. The data obtained from this study can potentially provide a clear and rapid clinical route forward by enabling more informed…

Good day. As CFO of Chemomab, I am pleased to have this opportunity to communicate directly with our shareholders and other stakeholders. Today, I will review highlights of our 2021 financial performance. Please see the press release we issued this morning for more detail. I will also briefly discuss our thoughts about the company's financial outlook for 2022. Our first-ever quarterly conference call is taking place during a particularly challenging time in the biotech industry. Like many of you, I have been through tough market cycles before, and know how painful they can be. However, I also know that downcycle's inevitably cycle to better times. And I believe this one will too. We cannot change the markets, but we can ensure that we are not distracted from focusing on what we need to do, to build a successful company. And for Chemomab management, that is to ensure we are pursuing the optimal development plan for CM-101, prudently managing our finances, to have achieved the greatest ROI on our investments, conserving capital to the extent feasible while advancing our clinical programs in as optimal fashion as possible, and monitoring our ecosystem for potential opportunities to bring additional attractive assets in house. Let me now share a summary of our financial performance in 2021. In addition to the detail included in today's press release, we also expect to be filing our 10-K Annual Report before the end of March. Cash and cash equivalents were $61.2 million as of December 31st, 2021, compared to $11.8 million as of December 31st, 2020. R&D expenses were $2.4 million for the quarter and $6.3 million for the full year ended December 31st, 2021, compared to $1.3 million and $4.7 million for the same quarter and year in 2020. G&A expenses were $2.6 million for the quarter…

We are excited about the revised clinical program we outlined today. I believe our team has done an outstanding job of developing practical and achievable plans to strengthen our clinical programs. We see CM-101 has great potential as a pipeline and a product with its ability to act it to confluence of inflammation and Fibrosis that is implicated in a variety of indications with high unmet medical need and strong commercial potential. We believe we are on the prudent and right path to building value at Chemomab. With our new plan over the next 24 months, we expect to: generate more informative milestones and catalysts, be better positioned for potential registrational trials, and achieve this while preserving capital. We look forward to sharing more details of our revised clinical programs with you in the next few months. And thank you for your continued support.

Thank you, Dale. This concludes our prepared remarks. Operator, we are ready for questions.

[Operator Instructions] A confirmation tone will indicate your line is in the question queue. [Operator Instructions] Please ask one question and one follow-up question, and then re-queue for additional questions. Our first question is from Kristen Kluska with Cantor Fitzgerald. Please proceed.

Hi. Good morning and good afternoon, everybody. Thanks for taking my question. They're all on systemic sclerosis. I wanted to ask; I understand some of the endpoints could differ based on you wanting to look at a more holistic package of effects on the different organs that play a role for these patients. But could you further comment on some of the trial design implementations you're considering at this point. For example, are you looking at changes across inclusion, exclusion, criteria to understand different levels of severity, or looking at different doses to study as well as length of time, or is it all of the above at this point?

Yes. Hi. It's all of the above at this point. We have changed the goals of what we're trying to achieve in SSc. And we're moving towards an exploratory and clinical proof-of-concept. And we're going to do exactly that. We believe CM-101 has a unique opportunity in this very heterogeneous disease to address multiple components, so rather than initially focusing on a composite endpoint, we intend to more deeply explore each of those individual components in a more -- in a revised trial design. And we intend to provide more clarity on that design in the coming months.

Okay. Got it. Thanks for that. And then my second and final question is, is this on the subcutaneous study? It sounds like based off this decision, that you think that there is at least enough definitive evidence for you to understand the effects with this type of formulation. So can you just confirm that? And then assuming that things read out positively, you're happy with the result, is the plan after these initial PSC and SSc studies to then consider moving into a subcutaneous trial?

Yes. We are continuing to explore the non-clinical aspects of the formulation and optimizing them. And later this year, when we get the readout from the liver fibrosis trial, which is the trial that is being conducted with the subcu formulation, that exposure and pharmacokinetic data will determine what our next steps in the clinical program are. And indeed the goal here is to advance that such, that it'll be either usable in our registration programs or soon thereafter.

Got it. Thanks so much for taking my questions.

Thank you.

[Operator Instructions]. Our next question is from Nathan Weinstein with Aegis Capital. Please proceed.

Thank you. Good morning, Dale, Adi, and Chemomab team. Thanks so much for taking my questions. And the first one is just on PSC regarding including a higher dose. What gives you the confidence to include the higher dose in the revised trial?

I'm not exactly sure we have that confidence, but we -- our desire here is to explore more than the single-dose that we're currently targeting [Indiscernible]. The rationale is to add a lower dose and a higher dose. We believe that the 20 -- the safety observed to date with CM-101 across all the populations, which is quite good, will support us advancing to the evaluation of the 20 mg per kg dosing in the PSC trial in the near future.

Okay. That's exactly what I was hoping to hear so I appreciate that. And then secondly, with the extended cash runway, I guess conceivably, does that take us through at least the initiation of a prospective registration study in one or both of the indications?

As we've stated before, we have sufficient cash to run the operations through the end of 2023. We will be investigating that further as trials designs become more formative, and we'll communicate that to the investment team maybe over the next couple months.

Okay. Okay. Fantastic. Thanks again for taking my questions. Appreciate it.

Thank you.

[Operator Instructions]. We will pause for a brief moment to poll for any final questions. There are no more questions at this time. I would like to turn the conference back over to management for closing comments.

Well, thank you very much for attending our first quarterly earnings call. I'm real proud of the team, and their processes that they've undertaken over the last couple of months to come to these adjustments to our clinical plans. I'm really excited about the potential. We're looking forward to updating you again in the May quarterly conference call. Thank you.

Thank you. This does conclude today's conference. You may disconnect your lines at this time and thank you for your participation.
