**EXPLANATORY NOTE**

This Amendment on Form 20-F/A (the "Amendment") amends the Annual Report on Form 20-F of XORTX Therapeutics Inc. ("XORTX" or the "Company") for the year ended December 31, 2021, as filed with the Securities and Exchange Commission on May 3, 2022 (the "Original Form 20-F"). This Amendment is being filed solely for the purpose of including disclosure that the Company inadvertently omitted from Item 5 of the Original Form 20-F relating to Use of Proceeds of the US IPO Financing (as defined in Item 5), a breakdown of R&D expenditures, a comparative analysis of the 12 months ended December 31, 2021, and disclosure of related party names.

This Amendment does not reflect events occurring after the filing of the Original Form 20-F and does not modify or update the disclosure therein in any way other than as required to reflect the amendments described herein and reflected below. No other changes have been made to the Original Form 20-F. The filing of this Amendment should not be understood to mean that any statements contained herein are true or complete as of any date subsequent to the date of the original filing of the Original Annual Report. Accordingly, this Amendment should be read in conjunction with our filings made with the Securities and Exchange Commission subsequent to the filing of the Original Form 20-F.

**General Matters**

Unless otherwise noted or the context indicates otherwise "we", "us", "our", the "Company" or "XORTX" refer to XORTX Therapeutics Inc. and its subsidiaries.

Unless otherwise indicated, financial information in this Amended Annual Report has been prepared in accordance with IFRS as issued by the IASB. Unless otherwise noted herein, all references to "$," "Canadian dollars," or "dollars" are to the currency of Canada and "US$," "United States dollars," or "U.S. dollars" are to the currency of the United States.

We are an "emerging growth company" as defined in the JOBS Act, and as such, we have elected to comply with certain reduced U.S. public company reporting requirements.

The Company prepares and reports its consolidated financial statements in accordance with IFRS. However, this Amended Annual Report may make reference to certain non-IFRS measures including key ‎‎performance indicators used by management. These measures are not recognized measures under IFRS ‎‎and do not have a standardized meaning prescribed by IFRS and are therefore unlikely to be comparable ‎‎to similar measures presented by other companies. Rather, these measures are provided as additional ‎‎information to complement those IFRS measures by providing further understanding of the Company's ‎results of ‎operations from management's perspective. Accordingly, these measures should not be ‎considered in ‎isolation nor as a substitute for analysis of the Company's financial information reported ‎under IFRS.

Unless otherwise indicated, the Company has obtained the market and industry data contained in this Amended Annual Report ‎from its internal research, management's estimates and third-party public information and other industry ‎publications. While the Company believes such internal research, management's estimates and third-‎party public information is reliable, such internal research and management's estimates have not been ‎verified by any independent sources and the Company has not verified any third party public ‎information. While the Company is not aware of any misstatements regarding the market and industry ‎data contained in this Amended Annual Report, such data involves risks and uncertainties and are subject to change based on ‎various factors, including those described under "Cautionary Statement Regarding Forward-Looking ‎Information and Statements" and "Item 3.D. Risk Factors".‎

**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This Amended Annual Report contains forward-looking statements that are subject to risks and uncertainties. These forward-looking statements include information about possible or assumed future results of our business, financial condition, results of operations, liquidity, plans and objectives. In some cases, you can identify forward-looking statements by terminology such as "believe," "may," "estimate," "continue," "anticipate," "intend," "should," "plan," "expect," "predict," "potential," or the negative of these terms or other similar expressions. The statements we make regarding the following matters are forward-looking by their nature and are based on certain of the assumptions noted below:

● the intentions, plans and future actions of the Company;

● statements relating to the business and future activities of the ‎Company;

● anticipated developments in operations of the Company;

● market position, ability to compete and future ‎financial or operating performance of the Company;

● the timing and amount of funding required to execute the ‎Company's business plans;

● capital expenditures;

● the effect on the Company of any changes to existing or new ‎legislation or policy or government regulation;

● ‎the availability of labor;

● requirements for and availability to us of additional capital;

● goals, strategies and future ‎growth;

● the adequacy of financial resources;

● expectations regarding revenues, ‎expenses and anticipated cash needs‎;

● the impact of the COVID-19 pandemic on the business and operations of the Company; and

● general market conditions and macroeconomic trends driven by the COVID-19 pandemic and/or geopolitical conflicts, including supply chain disruptions, market volatility, inflation, and labor challenges, among other factors.

The preceding list is not intended to be an exhaustive list of all of our forward-looking statements. The forward-looking statements are based on our beliefs, assumptions and expectations of future performance, taking into account the information currently available to us. These statements are only predictions based upon our current expectations and projections about future events. There are important factors that could cause our actual results, levels of activity, performance or achievements to differ materially from the results, levels of activity, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, those factors identified under the *Risk Factors* listed below in Item 3.D. of this Annual Report. Furthermore, unless otherwise stated, the forward-looking statements contained in this Annual Report are made as of the date hereof, and we have no intention and undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, changes or otherwise, except as required by law.

**Business Overview**

XORTX is a clinical-stage biotechnology company, focused on identifying, developing and commercializing therapies to treat progressive kidney disease modulated by aberrant purine and uric acid metabolism in orphan (rare) disease indications such as autosomal dominant polycystic kidney disease ("**ADPKD**") and larger, more prevalent type 2 diabetic nephropathy ("**T2DN**") as well as acute kidney injury ("**AKI**") associated with coronavirus infection.

Our focus is on developing three therapeutic products to:

1/ slow or reverse the progression of chronic kidney disease in patients at risk of end stage kidney failure;

2/ address the immediate need of individuals facing coronavirus induced AKI; and

3/ the identification of other opportunities where our existing and new intellectual property can be leveraged to address health issues.

We believe that our technology is underpinned by well-established research and insights into the underlying biology of aberrant purine metabolism, its health consequences and of oxypurinol, a uric acid lowering agent that works by effectively inhibiting xanthine oxidase. We develop therapeutic products that include new or existing drugs that can be adapted to address different disease indications where aberrant purine metabolism and/or elevated uric acid is a common denominator, including polycystic kidney disease, pre-diabetes, insulin resistance, metabolic syndrome, diabetes, diabetic nephropathy, and infection. We are focused on building a pipeline of assets to address the unmet medical needs for patients with a variety of serious or life-threatening diseases using our innovative formulation of oxypurinol, and our proprietary pipeline-in-a-product strategy supported by our intellectual property, established exclusive manufacturing agreements, and proposed clinical trials with experienced clinicians.

Our three lead product candidates are XRx-008, for the treatment of ADPKD; XRx-101, to treat AKI associated with Coronavirus / COVID-19 infection, AKI and associated health consequences; and XRx-225, for the treatment of T2DN. At XORTX; we aim to redefine the treatment of kidney diseases by developing medications to improve the quality-of-life of patients with life-threatening diseases by modulating aberrant purine and uric acid metabolism, including lowering elevated uric acid as a therapy.

**Our Proprietary Therapeutic Platforms**

Our expertise and understanding of the pathological effects of aberrant purine metabolism combined with our understanding of uric acid lowering agent structure and function, has enabled the development of our proprietary therapeutic platforms. These are a complementary suite of therapeutic formulations designed to provide unique solutions for acute and chronic disease. Our therapeutic platforms can be used alone, or in combination, with synergistic activity to develop a multifunctional tailored approach to a variety of indications that can address disease in multiple body systems through management of chronic or acute hyperuricemia, immune modulation, and metabolic disease. We continue to leverage these therapeutic platforms to expand our pipeline of novel and next generation drug-based therapies that we believe could represent significant improvements to the standard of care in multiple acute and chronic cardiovascular diseases and specifically kidney disease.

We believe our in-house drug design and formulation capabilities confer a competitive advantage to our therapeutic platforms and are ultimately reflected in our programs. Some of these key advantages are:

**Highly Modular and Customizable**

Our platforms can be combined in multiple ways and this synergy can be applied to address acute, intermittent or chronic disease progression. For example, our XRx-101 program for AKI is designed to produce rapid suppression of hyperuricemia then maintain purine metabolism at a low level during viral infection and target management of acute organ injury. Our XRx-008 program is designed for longer term stable chronic oral dosing of xanthine oxidase inhibitors. The capabilities of our formulation technology allow us to manage the unique challenges of cardiovascular and renal disease by modulating purine metabolism, inflammatory and oxidative state.

**Fit-for-purpose**

Our platforms can also be utilized to engineer new chemical entities and formulations of those agents that have enhanced properties. For example, our XRx-225 product candidate program, some of the intellectual property for which we license from third parties, represents a potential new class of xanthine oxidase inhibitor(s) with a targeted design to enhance anti-inflammatory activity. The capability of tailoring the therapeutic benefit of this class of new agents permits us to identify targets and disease that we wish to exploit and then, through formulation design, optimize those small molecules and proprietary formulations to maximize clinically meaningful therapeutic effect.

**Readily scalable and transferable**

Our in-house small molecule and formulations design expertise is positioned to create a steady succession of product candidates that are scalable, efficient to manufacture (by us or a partner or contract manufacturing organization), and produce large scale and high purity active pharmaceutical drug product. We believe this will provide a competitive advantage, new intellectual property and opportunity to provide first-in-class products that target unmet medical needs and clinically meaningful quality of life.

Our team's expertise in uric acid lowering agents, specifically in the development and use of xanthine oxidase inhibitors, has enabled the development of our therapeutic product candidates to treat the symptoms of, and potentially delay the progression of ADPKD, AKI associated with COVID-19 infection, and T2DN. We note that there is no guarantee that the FDA will approve our proposed uric acid lowering agent products for the treatment of kidney disease or the health consequences of diabetes.

**Product Candidate Pipeline**

Our lead product candidates are XRx-008, XRx-101, and XRx-225. The XRx-008 program is currently screening subjects for bridging pharmacokinetic characterization before initiating a Phase 3 registration clinical trial, the last stage of clinical development before United States Food and Drug Administration ("**FDA**") approval. Similarly, a second "pharmacokinetic" study is planned to support both the XRx-008 and XRx-101 program and future late-stage clinical studies targeting attenuation or reversal of acute kidney disease in hospitalized individuals with COVID-19. XRx-225 is at the non-clinical stage and advancing toward the clinical development stage.

**Products**

The Company's most advanced development program, XRx-008, is a late clinical stage program focused on demonstrating the potential of our novel therapy for ADPKD. XRx-008 is the development name given to XORTX's proprietary oral formulation of oxypurinol. This proprietary formulation of oxypurinol has shown increased oral bioavailability and the potential for an enhanced therapeutic range. XORTX is also developing a second oral formulation of oxypurinol, XRx-101, for use in treating patients with AKI due to respiratory virus infection and/or associated co-morbidities including sepsis.

XORTX is currently evaluating xanthine oxidase inhibitor candidates for the XRx-225 program to treat T2DN as well as developing new chemical entities to address the large unmet medical need.

**Patents**

XORTX is the exclusive licensee of two U.S. granted patents with claims to the use of all uric acid lowering agents to treat insulin resistance or diabetic nephropathy. Counterparts for some of these patent applications have also been submitted in Europe. In both the US and Europe, XORTX has been granted patents for unique proprietary formulations of xanthine oxidase inhibitors. In addition, XORTX has also submitted two patent applications to cover the use of uric acid lowering agents for the treatment of the health consequences of coronavirus infection, as well as a new provisional patent for novel therapeutics to treat polycystic kidney disease.

**Our Strategy**

The Company's goal is to apply our interdisciplinary expertise and pipeline-in-a-product strategy to further identify, develop and commercialize novel treatments in orphan indications, with an initial focus on renal and significant unmet medical needs.

Our ability to implement our business strategy is subject to numerous risks.

These risks include, among others (see "Risks Related to the Business"):

● we have incurred significant losses since inception and anticipate that we will continue to incur losses for the foreseeable future;

● we will require substantial additional funding, which may not be available to us on acceptable terms, or at all, and, if not available, may require us to alter, delay, scale back, or cease our product development programs or operations;

● we have not generated any revenue to date and may never be profitable;

● we have a limited number of product candidates, all of which are still in preclinical or clinical development, and we may fail to obtain regulatory approval or experience significant delays in doing so;

● our product candidates may have undesirable side effects that may delay or prevent marketing approval or, if approved, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales;

● we may be unable to obtain regulatory approval for our product candidates under applicable regulatory requirements, and the denial or delay of any such approval would delay commercialization of our product candidates and adversely impact our potential to generate revenue, our business and our results of operations;

● security breaches, loss of data and other disruptions could compromise sensitive information related to our business or protected health information or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and our reputation;

● the COVID-19 pandemic may materially and adversely affect our business and financial results;

● our existing strategic partnerships are important to our business, and future strategic partnerships may also be important to us; if we are unable to maintain any of these strategic partnerships, or if these strategic partnerships are not successful, we may not realize the anticipated benefits of our strategic partnerships and our business could be adversely affected;

● we rely on third parties to monitor, support, conduct and oversee clinical trials of the product candidates that we are developing and, in some cases, to maintain regulatory files for those product candidates;

● our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties;

● our patents covering one or more of our products or product candidates could be found invalid or unenforceable if challenged;

● if we are unable to obtain, maintain and enforce patent and trade secret protection for our product candidates and related technology, our business could be materially harmed; and

● if we are unable to protect the confidentiality of our proprietary information, the value of our technology and products could be adversely affected.

**Funding Requirements**

The Company has not generated any revenue from product sales to date and does not expect to do so until such time as XORTX obtains regulatory approval for and commercializes one or more of our product candidates. As the Company is currently in clinical and preclinical stages of development, it will be some time before we expect to achieve this and it is uncertain that we ever will. We expect that we will continue to increase our operating expenses in connection with ongoing clinical trials and preclinical activities and the development of product candidates in our pipeline. We also expect to continue our strategic partnerships and we continue to seek additional collaboration opportunities. Further, we expect to continue our efforts to pursue additional grants and refundable tax credits from the Canadian government in order to further our research and development. Although it is difficult to predict our funding requirements, based upon our current operating plan, the Company anticipates that our existing cash and cash equivalents as of December 31, 2021, combined with the net proceeds of future financings, will enable us to advance the clinical development of XRx-008 and XRx-101 product candidates. XORTX may also be eligible to receive certain research, development and commercial milestone payments in the future. However, because successful development of our product candidates and the achievement of milestones by our strategic partners is uncertain, we are unable to estimate the actual funds we will require to complete the research, development and commercialization of product candidates.

**Recent Developments**

**Consolidation and Exchange Uplistings**

On September 20, 2021, the Company announced that further to receipt of shareholder approval at the special meeting of shareholders held September 2, 2021 (announced on August 13, 2021), the Company would complete a share consolidation of the issued and outstanding common shares of the Company on the basis of 11.74 pre-consolidation common shares for each one (1) post-consolidation common share. On September 24, 2021, the share consolidation was affected resulting in consolidated shares outstanding on that date of 9,528,687.

On October 13, 2021, the Company announced that it had received approval to list its common shares on the Nasdaq under the symbol "XRTX".

On November 2, 2021, the Company announced that it had received final approval to list its common shares on the TSXV under the symbol "XRTX". The Company's shares were de-listed from trading on the Canadian Securities Exchange effective November 4, 2021 and trading on the TSXV commenced on November 5, 2021.

**Public Offering and Private Placement**

On October 15, 2021, the Company closed an underwritten public offering in the U.S. of 2,906,000 units, with each unit consisting of one common share and one warrant to purchase one common share at US$4.13 per unit, for aggregate gross proceeds of approximately US$12 million, prior to deducting underwriting discounts and other offering expenses (the "**US IPO Offering**"). The USD IPO Offering was undertaken by A.G.P. / Alliance Global Partners ("**A.G.P.**") who acted as sole book-running manager. The warrants are exercisable at US$4.77 per share and have a term of five years. In addition, the Company granted A.G.P. a 45-day option to purchase up to an additional 435,900 common shares and warrants to purchase up to an additional 435,900 common shares at US$4.13 less underwriting discounts. On closing, A.G.P. exercised its option to purchase additional warrants to purchase up to an additional 435,900 common shares. On November 8, 2021, A.G.P. partially exercised its 45-day option to purchase 355,000 common shares at US$4.13 per share, resulting in additional gross proceeds to the Company of approximately US$1.47 million which increased the US IPO Offering to 3,261,000 common shares and 3,341,900 warrants.

In January and February 2021, 350,204 warrants that were issued in connection with the February 2020 private placement were exercised. Of the warrants exercised, 339,801 were exercised at $2.94 per common share and 10,703 were exercised at $1.64 per common share in respect to certain finder's warrants that were issued in relation to that private placement.

On February 9, 2021, the Company closed a private placement with the issuance of 2,085,687 units at a subscription price of $2.935 per unit for gross proceeds of $6,121,572 (the "**Private Placement**"). Each unit comprised one common share and one common share purchase warrant. Each warrant entitles the holder, on exercise, to purchase one additional common share in the capital of the Company, at a price of $4.70 for a period of five years from the issuance of the units; provided, however, that, if, at any time following the expiry of the statutory four month hold period, the closing price of the common shares is greater than $14.09 (adjusted to reflect the share consolidation of 11.74:1 effected on September 24, 2021) for 10 or more consecutive trading days, the warrants will be accelerated upon notice and the warrants will expire on the 30<sup>th</sup> calendar day following the date of such notice. In addition, the warrants were also subject to a ratchet provision that provided for an adjustment in the exercise price in the event the Company issued or sold common shares or securities convertible into common shares at a price (or conversion price, as applicable) less than the exercise price such that the exercise price would be amended to match such lower price. With the US IPO Offering being undertaken at a higher price than the Private Placement, the ratchet provision terminated on October 15, 2021.

In connection with the Private Placement, the Company paid $116,216 in cash commissions and issued 58,288 finders' warrants. Each finders' warrant is exercisable into one common share at a price of $4.70 and having the same expiry, acceleration and anti-dilution provisions as the warrants included in the Private Placement.

As at the date of this MD&A, the Company has used approximately CAD$3,000,000 of the proceeds of the US IPO Offering for funding operations and general corporate purposes, which included further research and development, clinical trials, and manufacture of active pharmaceutical ingredients and drug product to support clinical trials. The Company intends to use the remaining net proceeds of the US IPO Offering, together with existing cash, for funding operations and general corporate purposes, which may include further research and development, clinical trials, manufacture of active pharmaceutical ingredients and drug product to support clinical trials.

**Patent Advancements**

On December 29, 2020, the Company announced the receipt of notification that the patent "Formulations of Xanthine Oxidase Inhibitors" will be granted for XRx-225 by the European Patent Office. The patent covers compositions and methods of using XORTX's proprietary formulations of xanthine oxidase for, renal and other diseases where aberrant purine metabolism has been implicated in disease progression. On September 1, 2021, the Company announced the grant of the patent titled "EPO National Stage of PCT International Application for Compositions and Methods for Treatment and Prevention of Hyperuricemia Related Health Consequences".

On March 16, 2020, XORTX announced the filing of a provisional patent application covering the potential use of any uric acid lowering agent, and more specifically a xanthine oxidase inhibitor XRx-101 (we believe a novel formulation of oxypurinol), to treat respiratory, kidney disease and multi-organ injury related to patients infected with SARS-COV-2 or other respiratory viruses COVID-19.

On December 20, 2021, the Company filed a provisional patent for polycystic kidney disease entitled "Compositions and Methods for Diagnosis, Treatment of and Prevention of Kidney Disease". This provisional patent filing was based upon findings of two independent investigator led studies that: (1) studied the role of aberrant purine metabolism in ADPKD kidney tissue, the results showing that xanthine oxidase enzyme expression and activity in kidney tissue in ADPKD is increased substantially and significantly, potentially revealing a new mechanism of injury in ADPKD; and (2) explored the health consequences of high uric acid in a mouse model of autosomal dominant polycystic kidney disease that successfully demonstrated that increased levels of serum uric acid can accelerate structural and functional changes in kidneys of patients with ADPKD.

On March 23, 2022, the Company announced the submission of a Patent Cooperation Treaty ("**PCT**") patent application seeking international patent protection for the patent entitled "Compositions and Methods for Enhancing Anti-Viral Therapies". This patent is based on retrospective clinical data from XORTX scientific partners suggesting that an important therapeutic opportunity lies with addressing aberrant purine metabolism combined with hyperuricemia in patients most at risk to severe COVID-19 outcome. Since the advent of COVID-19 and during 2020, accumulating evidence suggests that individuals most at risk for more severe health consequences fall within a group that includes individuals with obesity, hypertension, metabolic syndrome, insulin resistance, pre-diabetes, diabetes or chronic kidney disease have a higher incidence of hyperuricemia and endothelial dysfunction. Low grade systemic inflammation associated with these disease states and pre-existing vascular injury may suppress an individual's ability to respond with a sufficiently robust response to fight infection and leaves the individual more prone to excessive pro-inflammatory and pro-coagulative state. This new patent filing proposes compositions and methods for enhancing anti-viral therapies for the treatment of individuals most at risk.

On April 7, 2022, the Company announced receipt of notification that the patent "Formulations of Xanthine Oxidase Inhibitors" will be granted by the United States Patent Office. The patent covers compositions for, and methods of using XORTX's proprietary formulations of xanthine oxidase inhibitors for renal and other diseases where aberrant purine metabolism has been implicated in disease progression.

**Regulatory Advancements**

On March 14, 2022, the Company announced the submission of its clinical trial application ("**CTA**") with Health Canada for a XRX-OXY-101 bridging pharmacokinetics study. The study is an important first clinical step in the Company's 505(b)2 clinical and regulatory plan for 2022 and will support the XRx-008 program for ADPKD as well as the planned phase 3 registration trial.

On March 31, 2022, the Company announced the filing of an IND application with the FDA. This IND filing is in support of the Company's XRx-008 program for treatment of progressing kidney disease due to ADPKD and contains the protocol for the bridging pharmacokinetics study – XRX-OXY-101 discussed below.

On April 12, 2022, the Company announced receipt of a no objection letter from Health Canada regarding the Company's upcoming XRX-OXY101 clinical bridging pharmacokinetics study. The XRX-OXY-101 study has been designed with three important objectives: 1) to determine which of XORTX's novel formulations results in the best circulating oxypurinol concentrations; 2) to determine the effect of food on the bioavailability of this formulation; and 3) to determine the safety and pharmacokinetics of multiple doses of this selected formulation. Knowledge gained during the conduct of this trial will provide guidance regarding the future oral dosing of oxypurinol formulations in support of the Company's planned phase 3 registration trial in ADPKD. Additionally, this study will provide data to support future New Drug Application ("**NDA**") marketing submissions to the FDA and the European Medicines Agency ("**EMA**").

**Partnership with Icahn School of Medicine**

On November 16, 2020, the Company announced the topline results from the Company's partnership with the Icahn School of Medicine at Mount Sinai, New York. The aim of this study was to characterize the incidence of AKI and hyperuricemia in patients hospitalized with COVID-19. The results of the data analysis show that in some individuals with COVID-19 infection, hyperuricemia increases early in and is associated with AKI. The data also strongly suggest that for those individuals with very high serum uric acid levels, this can contribute to worsening kidney outcomes. These topline results indicate that further clinical studies to lower uric acid in these individuals are warranted, and may improve AKI, dialysis, recovery and mortality outcomes.

On October 14, 2021, the Company announced that the results of the study provide support for the Company's provisional patent applications for XRx-101 with the conclusion of the study indicating, *"In patients admitted to the hospital for COVID-19, higher uric acid levels were independently associated with major adverse kidney events and mortality in a dose-dependent manner. In addition, hyperuricemia was associated with higher procalcitonin and troponin levels."*

**Appointment of LONZA Group as Manufacturer**

On April 30, 2020, the Company announced the appointment of LONZA Group as the manufacturer of GMP oxypurinol for the XRx-008 and XRx-101 clinical trial programs. The launch of oxypurinol manufacturing for both XRx-008 and XRx-101 is the first step to advance these programs toward clinical testing. Lonza is a leading global supplier to the pharmaceutical, biotech and specialty ingredients markets.

**Appointment of Altasciences as Contract Research Organization**

On December 2, 2021, the Company announced the appointment of Altasciences Company Ltd., a contract research organization ("**CRO**") for its planned Bridging pharmacokinetic study in support of the XRx-008 program for ADPKD and XRx-101 for AKI associated with Coronavirus / COVID-19 infection. The goal of the planned bridging pharmacokinetics study – XRX-OXY-101, is to characterize the increased bioavailability of oxypurinol in humans and follows successful results in two animal models where increased bioavailability was demonstrated for this formulation.

**Changes in officers, directors and advisory board members**

On May 12, 2021, William Farley was appointed to the Board of Directors of the Company.

On June 16, 2021, Jacqueline Le Saux was appointed to the Board of Directors to replace Allan Williams who resigned effective that date.

On July 1, 2021, Stephen Haworth was appointed as the Chief Medical Officer of the Company.

On July 14, 2021, Amar Keshri was appointed as Chief Financial Officer to replace James Fairbairn.

On August 31, 2021, the Company announced the appointment of Dr. Charles Edelstein to the Company's clinical advisory board.

On December 20, 2021, Raymond Pratt was elected to the Board of Directors to replace Bruce Rowlands who resigned effective that date.

On January 20, 2022, the Company announced the appointment of Dr. David MacDonald as Chief Technology Officer.

**Future Plans and Outlook**

XORTX intends to grow its business by developing three programs focused on kidney disease.

For the balance of 2022, the Company anticipates a number of advancements and changes in its business.

In 2022, XORTX is focused on advancing XRx-008 into a clinical trial, the submission of an Orphan Drug Designation application, initiation of special protocol assessment discussions with the FDA and continuing formulation development for other kidney disease applications. To achieve these objectives, XORTX's action plan includes:

1. **Initiate XRX-OXY-101 Bridging Study.** This study is a three-part, single-dose; fed or fasted; then,
 multi-dose crossover comparative bioavailability and pharmacokinetic study in healthy volunteers.
 It is designed to permit XORTX to characterize the safety and relative bioavailability of
 the XRx-008 formulation. Knowledge gained during the conduct of this trial will provide guidance
 regarding the oral dose of XRx-008 for our planned registration trial in ADPKD. Additionally,
 this study will provide data to support future **NDA** submissions to the FDA and the
 EMA. This study is planned to start in the second quarter of 2022.

2. **Initiate XRX-OXY-102 Bridging Study.** This study is a multi-dose crossover comparative bioavailability
 and pharmacokinetic study in healthy volunteers. It is designed to permit XORTX to characterize
 the safety and relative bioavailability of the XRx-101 formulation options. Knowledge gained
 during the conduct of this trial will provide guidance regarding the oral dose of XRx-101
 for future clinical and commercial planning. Additionally, this study will provide data to
 support future NDA submissions to the FDA and EMA. This study is planned to start in the
 second quarter of 2022.

3. **Complete Orphan Drug Designation.** Current research being conducted will be used to file for orphan
 drug designation in 2022.

4. **Commence XRX-OXY-301 Registration trial in ADPKD.** XRX-OXY-301 is a multi-site, multi-national,
 placebo controlled, study in ADPKD patients with progressing stage 2 or 3 kidney disease.
 The objective of this study is to evaluate the safety and effectiveness of XRx-008 over a
 24-month period and study the ability of xanthine oxidase inhibition to decrease the rate
 of decline of glomerular filtration rate. An estimated 350 patients will be enrolled. This
 study is planned to start in the second half of 2022, subject to SPA negotiations with the
 FDA.

5. **Ongoing CMC Work.** In parallel to the XRX-OXY-101 and XRX-OXY-102 studies, XORTX will be focused
 on performing the necessary scale-up, process validation and stability as part of the CMC
 requirements for the filing of the IND, as well as future clinical and commercial supplies.
 All development will be performed according to current GMP methodology. This work will be
 ongoing throughout 2022 and 2023.

6. **Preparation of 505(b)(2) IND.** In parallel with initiation of XRX-OXY-101 a 505(b)2 based IND
 is expected to be submitted in the second quarter of 2022 for the XRx-008 program.

7. **Activities Related to Potential Commercial Launch.** In preparation for a possible NDA filing in
 2025 in the U.S. for XRx-008, XORTX is planning to conduct additional commercialization studies,
 including nephrologist, patient, payer, pricing and/or reimbursement studies, as well as
 product brand name selection and filings, and plans for launch. This work will be ongoing
 from 2022 to 2025.

8. **Activities Related to European Registration.** XORTX intends to establish guidance from the European
 Union for path to approval in the European Union, including required clinical studies and
 reimbursement conditions. This work will be ongoing from 2022 to 2025.

To achieve the above goals, XORTX will continue to pursue non-dilutive and dilutive funding and expand discussions to partner with major pharma / biotech companies with a global reach. XORTX will also increase financial and healthcare conference participation to further strengthen and expand our investor base.

---

Notes:

(1) Manufacturing and related process expenses
 includes third party direct manufacturing costs, quality control testing and packaging costs.
 In Q4 2021, manufacturing costs primarily related to the Company's oxypurinol manufacturing,
 feasibility study and chemical compound studies. The decrease in manufacturing and related
 process expenses in Q4 2021 as compared to Q4 2020 relates to a timing difference as fiscal
 2021 manufacturing and related expenses overall were higher than yearly 2020 costs geared
 towards the start of bridging study and registration trial in ADKPD planned for 2022.

(2) Intellectual property expenses include legal
 and filing fees associated with our patent portfolio. The increase in intellectual property
 expenses in Q4 2021 as compared to Q4 2020 relate to increased legal fees as the Company
 expanded its patent portfolio.

(3) Translational science expenses include various
 research studies conducted to expand our intellectual knowledge base related to oxypurinol
 and our proprietary formulations of oxypurinol, pharmacokinetic testing, non-clinical bioavailability
 studies, pharmacology and toxicology testing and identify potential licensing opportunities.
 The translational science expense in Q4 2021 related to sponsored research work at the University
 of Denver, Colorado and Mount Sinai Hospital, New York. No such activity was undertaken in
 2020.

(4) External consultants' expenses include
 third party consultants engaged in the activities of research and development, including
 chemistry, manufacturing, drug product development, regulatory, non-clinical and clinical
 study execution. The increase in external consultants' expenses in Q4 2021 as compared
 to Q4 2020 was attributed to increased activity focused on to initiation of the Company's
 bridging study and thereafter a single registration trial associated to the XRx-008 program
 in individuals with ADKPD planned for 2022.

***Share-based payments*** - $143,496 (2020 - $6,748) – The share-based payment expense increased in the three months ended December 31, 2021, as more options were granted that vested over the period.

***Gain on derivative warrant liability*** - $11,895,882 (2020 – nil). This gain relates to the warrants included in the units issued under the Private Placement and IPO. The Private Placement warrants were classified as a derivative financial liability as they contained a ratchet provision that provided for an adjustment in the exercise price of the warrants if shares or securities convertible to shares were sold at a price lower than the exercise price. The IPO warrants have an exercise price in US dollars and have a derivative financial liability as the exercise price is in a different currency than the functional currency of the entity. The warrants are initially recognized at fair value and subsequently measured at fair value with changes recognized through profit or loss. Of this amount, a gain of $9,068,213 relates to the Private Placement warrants and was recognized as the ratchet provision on the warrants described above ended, thereby resulting in the derecognition of the derivative warrant liability during the quarter. A gain of $2,827,669 relates to the IPO warrants and the derivative liability recognized. Gains and losses resulting from the revaluation of the derivative warrants are non-cash and do not impact our cash flows.

Notes:

(1) Manufacturing and related process expenses
 include third party direct manufacturing costs, quality control testing and packaging costs.
 In 2021, the Company's manufacturing costs primarily related to oxypurinol manufacturing,
 feasibility study and chemical compound studies. The increase in manufacturing and related
 process expenses in 2021 as compared to 2020 is entirely attributable to increased activity
 geared towards the start of bridging study and registration trial in ADKPD planned for 2022.
 We expect our manufacturing expenses for 2022 to increase as compared to 2021 as we start
 the drug manufacturing for bridging study and registration trials in ADKPD as per future
 plan.

(2) Intellectual property expenses include legal
 and filing fees associated with our patent portfolio. The increase in intellectual property
 expenses in 2021 as compared to 2020 related to increased legal fees as company expanded
 its patent portfolio. We expect intellectual property expenses in 2022 will increase as compared
 to 2021 as the Company expands its patent portfolio.

(3) Translational science expenses include various
 research studies conducted to expand our intellectual knowledge base related to oxypurinol
 and our proprietary formulations of oxypurinol, pharmacokinetic testing, non-clinical bioavailability
 studies, pharmacology and toxicology testing and identification of potential licensing opportunities.
 The translational science expense in 2021 related to sponsored research work at the University
 of Denver, Colorado and Mount Sinai Hospital, New York. No such activity was undertaken in
 2020. We expect translational science expense in 2022 will increase as compared to 2021 as
 the Company expands its patent portfolio.

(4) External consultants' expense includes
 third party consultants engaged in the activities of research and development, including
 chemistry, manufacturing, drug product development, regulatory, non-clinical and clinical
 study execution. The increase in external consultants' expenses in 2021 as compared
 to 2020 was attributed to increased activity focused on the initiation of the Company's
 bridging study and thereafter a single registration trial associated with the XRx-008 program
 in individuals with ADKPD planned for 2022. We expect external consultants' expense
 in 2022 to increase as compared to 2021 as the Company conducts a bridging pharmacokinetic
 study associated with the XRx-008 drug product and thereafter initiation and conduct of a
 registration trial in ADKPD.

(5) Other related expenses include various ancillary
 research and development costs. The expense in 2021 is entirely related to patent portfolio
 research and development expense. No such cost incurred in 2020. We expect other related
 expense in 2022 will remain same as compared to 2021.

***Share-based payments*** - $499,158 (2020 - $293,443) – The share-based payment expense increased in the year ended December 31, 2021, as more options were granted than vested over the period.

***Foreign exchange gain*** - $326,751 (2020 - $2,961) – Our foreign exchange gain was $326,751 for the year ended December 31, 2021 as compared to loss of $2,961 primarily due to an unrealized translation gain on the U.S. dollar denominated cash balance.

***Transaction costs on derivative warrant liability and gain on derivative warrant liability*** – an expense of $1,623,680 and a gain of $3,299,768 respectively (2020 – $nil and $nil). The expense and gain relate to the warrants included in the units issued under the Private Placement and IPO. The transaction costs result from the valuation of finders' warrants and the gain on derivative liability resulting from the revaluation of the warrants issued as part of a unit. The Private Placement warrants were classified as a derivative financial liability as they contained a ratchet provision that provided for an adjustment in the exercise price of the warrants if shares or securities convertible to shares were sold at a price lower than the exercise price. The IPO warrants have an exercise price in US dollars and have a derivative financial liability as the exercise price is in a different currency than the functional currency of the entity. The warrants are initially recognized at fair value and subsequently measured at fair value with changes recognized through profit or loss. Gains and losses resulting from the revaluation of the derivative warrants are non-cash and do not impact our cash flows.

**Comparison of cash flows for the year ended December 31, 2021**

The Company realized a net cash inflow of $18,679,973 for the year ended December 31, 2021, compared to $112,657 for the year ended December 31, 2020. The variances in the cash flow for the year ended December 31, 2021, compared to December 31, 2020. were as follows:

***Operating activities*** – Cash used in operating activities for the year ended December 31, 2021, was $6,062,510 (2020 - $728,401). The cash used in operating activities was primarily due to the net loss during the period offset by the non-cash items.

***Investing activities*** – Cash used in investing activities for the year ended December 31, 2021, was $39,809 (2020 - $14,350). The cash used related to the acquisition of intangible assets during the period.

***Financing activities*** – Cash provided by financing activities in the year ended December 31, 2021, was $24,456,551 (2020 - $855,408). The cash provided was mostly related to the public offering that occurred when the shares of the Company were listed on Nasdaq of 2,906,000 units, with each unit consisting of one common share, no par value, and one warrant to purchase one common share at a public offering price of US$4.13 per Unit, for gross proceeds of $14,851,850 (US$12,001,780) as well as the private placement that took place in February 2021 raising gross proceeds of $6,121,572 through the issuance of 2,085,687 units at a subscription price of $2.935 per unit.

**Liquidity and Capital Resources**

As at December 31, 2021, the Company had a cash balance of $18,851,244 and working capital of $19,472,340 as compared to a cash balance of $171,271 and working capital of $1,021,928 as at December 31, 2020. During the year ended December 31, 2020, the Company closed a $2,556,320 private placement and during the year ended December 31, 2021, the Company closed a public offering that occurred when the shares of the Company were listed on Nasdaq of 2,906,000 units, with each unit consisting of one common share, no par value, and one warrant to purchase one common share at a public offering price of US$4.13 per Unit, for gross proceeds of $14,851,850 (US$12,001,780) as well as the private placement that took place in February 2021 raising gross proceeds of $6,121,572 through the issuance of 2,085,687 units at a subscription price of $2.935 per unit. The Company's primary source of funding is by way of raising capital through the issuance of equity to third party investors.

Although there is no certainty, management is of the opinion that additional funding for its projects and operations can be raised as needed. The Company is subject to a number of risks associated with the successful development of new products and their marketing and the conduct of its clinical studies and their results. The Company will have to finance its research and development activities and its clinical studies. To achieve the objectives in its business plan, the Company plans to raise the necessary capital and to generate revenues. It is anticipated that the products developed by the Company will require approval from the FDA and equivalent organizations in other countries before their sale can be authorized. If the Company is unsuccessful in obtaining adequate financing in the future, corporate initiatives may be affected or postponed.

\* The Company has determined that the carrying values of its short-term financial assets and financial liabilities, including cash and accounts payable and accrued liabilities approximate their fair value due to the short-term nature of the instruments. The fair value of the derivative warrant liability is revalued at the end of each period.

There were no transfers for levels of change in the fair value measurements of financial instruments for the years ended December 31, 2021 and 2020.

Risk management is carried out by the Company's management team with guidance from the Board of Directors. The Company's risk exposures and their impact on the Company's financial instruments were as follows:

**a)** **Credit risk** 

Credit risk is the risk of financial loss to the Company if a customer of counterparty to a financial instrument fails to meet its obligations. The Company's maximum exposure to credit risk at the financial position date under its financial instruments is summarized as follows:

---

| | | |
|:---|:---|:---|
|  | **December 31,<br> 2021** | **December 31,<br> 2020** |
|  | **$** | **$** |
| **Cash** | 18851244 | 171271 |

---

All of the Company's cash is held with major financial institutions in Canada and management believes the exposure to credit risk with such institutions is minimal. The Company considers the risk of material loss to be significantly mitigated due to the financial strength of the major financial institutions where cash is held. The Company's maximum exposure to credit risk as at December 31, 2021 and 2020 is the carrying value of its financial assets.

**b)** **Liquidity risk** 

Liquidity risk is the risk that the Company will not be able to meet its obligations associated with financial liabilities. The Company has a planning and budgeting process in place by which it anticipates and determines the funds required to support normal operation requirements as well as the growth and development of its intellectual property portfolio.

The Company's financial assets are comprised of its cash and funds held in trust, and the financial liabilities are comprised of its accounts payable and accrued liabilities and the liability component on convertible loans.

The contractual maturities of these financial liabilities as at December 31, 2021 and 2020 are summarized below:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Payments due by period as of December 31, 2021** | **Payments due by period as of December 31, 2021** | **Payments due by period as of December 31, 2021** | **Payments due by period as of December 31, 2021** |

| Accounts payable and accrued liabilities | 1034213 | 1034213 |  |  |
|  | 1034213 | 1034213 |  |  |

---

**c)** **Market risk** 

&nbsp;&nbsp;&nbsp;&nbsp;i) Interest Rate Risk

Interest rate risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate due to changes in market interest rates. The Company's bank accounts bear interest. Management believes that the credit risk concentration with respect to financial instruments included in cash is minimal.

ii) Foreign Currency Risk

As at December 31, 2021, the Company is exposed to currency risk on the following financial assets and liabilities denominated in US Dollars ("**USD**") and British Pounds ("**GBP**"). The sensitivity of the Company's net earnings due to changes in the exchange rate between the USD and GBP against the Canadian dollar is included in the table below in Canadian dollar equivalents:

---

|:---|
| Cash |
| Accounts payable and accrued liabilities |
| **Net exposure** |
| **Effect of +/- 10% change in currency** |

**Capital Management**

The Company defines capital that it manages as equity. The Company manages its capital structure in order to have funds available to support its research and development and sustain the future development of the business. When managing capital, the Company's objective is to ensure the entity continues as a going concern as well as to maintain optimal returns to shareholders and benefits for other stakeholders. Management adjusts the capital structure as necessary in order to support its activities.

The Company includes the following items in its managed capital as at the following periods:

**Equity is comprised of:**

---

| | | |
|:---|:---|:---|
|  | **December 31**<br> **2021** | **December 31**<br> **2020** |
|  | **$** | **$** |
| Share capital |  |  |
| Share-based payments, warrant reserve and other |  |  |
| Obligation to issue shares |  |  |
| Deficit) |  |  |

---

Since inception, the Company's objective in managing capital is to ensure sufficient liquidity to finance its research and development activities, general and administrative expenses, expenses associated with intellectual property protection and its overall capital expenditures. The Company is not exposed to external requirements by regulatory agencies regarding its capital.

**Risks Related to the Business**

An investment in the Company is speculative and involves a high degree of risk. Accordingly, prospective investors should carefully consider the specific risk factors set out below, in addition to the other information contained in this MD&A, before making any decision to invest in the Company. The Directors consider the following risks and other factors to be the most significant for potential investors in the Company, but the risks listed do not necessarily comprise all those associated with an investment in the Company and are not set out in any particular order of priority. Additional risks and uncertainties not currently known to the Directors may also have an adverse effect on the Company's business. If any of the following risks actually occur, the Company's business, financial condition, capital resources, results or future operations could be materially adversely affected. In such a case, the price of the common shares could decline, and investors may lose all or part of their investment.

**Speculative Nature of Investment Risk**

An investment in the common shares of the Company carries a high degree of risk and should be considered as a speculative investment by purchasers. The Company has limited cash reserves, a limited operating history, has not paid dividends, and is unlikely to pay dividends in the immediate or near future. The Company is in the development stage. Operations are not yet sufficiently established such that the Company can mitigate the risks associated with planned activities.

**Limited Operating History**

The Company has no present prospect of generating revenue from the sale of products. The Company is therefore subject to many of the risks common to early-stage enterprises, including under-capitalization, cash shortages, limitations with respect to personnel, financial, and other resources and lack of revenues. There is no assurance that the Company will be successful in achieving a return on shareholders' investment and the likelihood of success must be considered in light of the early stage of operations.

**Negative Cash Flow for the Foreseeable Future**

The Company has a no history of earnings or cash flow from operations. The Company does not expect to generate material revenue or achieve self-sustaining operations for several years, if at all. To the extent that the Company has negative cash flow in future periods, the Company may need to allocate a portion of its cash reserves to fund such negative cash flow.

**Reliance on Management**

The success of the Company is dependent upon the ability, expertise, judgment, discretion and good faith of its management. While employment agreements are customarily used as a primary method of retaining the services of key employees, these agreements cannot assure the continued services of such employees. Any loss of the services of such individuals could have a material adverse effect on the Company's business, operating results or financial condition.

**Clinical trials for potential drug candidates will be expensive and time consuming, and their outcomes uncertain.**

Before the Company can obtain regulatory approval for the commercial sale of any drug candidate or attract major pharmaceutical companies with which to collaborate, it will be required to complete extensive clinical trials to demonstrate safety and efficacy. Clinical trials are expensive and are difficult to design and implement. The clinical trial process is also time-consuming and can often be subject to unexpected delays.

The timing and completion of clinical trials may be subject to significant delays relating to various causes, including but not limited to: inability to manufacture or obtain sufficient quantities of materials for use in clinical trials; delays arising from collaborative partnerships; delays in obtaining regulatory approvals to commence a study, or government intervention to suspend or terminate a study; delays, suspensions or termination of clinical trials by the applicable institutional review board or independent ethics board responsible for overseeing the study to protect research subjects; delays in identifying and reaching agreement on acceptable terms with prospective clinical trial sites; slow rates of patient recruitment and enrollment; uncertain dosing issues; inability or unwillingness of medical investigators to follow clinical protocols; variability in the number and types of subjects available for each study and resulting difficulties in identifying and enrolling subjects who meet trial eligibility criteria; scheduling conflicts; difficulty in maintaining contact with subjects after treatment, resulting in incomplete data; unforeseen safety issues or side effects; lack of efficacy during clinical trials; reliance on clinical research organizations to efficiently and properly conduct clinical trials in accord with contracted arrangements and regulations, or other regulatory delays.

**Risks Related to Food and Drug Administration (FDA) Approval**

In the United States, the FDA regulates the approval of therapeutics and the FDA notification and approval process requires substantial time, effort and financial resources, and the Company cannot be certain that any approvals for its products will be granted on a timely basis, if at all.

Foreign jurisdictions have similar government regulatory bodies and requirements that the Company must meet prior to selling products in those jurisdictions.

The Company must be considered in light of the risks, expenses, shifts, changes and difficulties frequently encountered with companies whose businesses are regulated by various federal, state and local governments. The health care, wellness, workers' compensation and similar companies are subject to a variety of regulatory requirements and the regulatory environment is ever changing particularly with recent legislation, the full impact of which is not yet understood as regulations have not been issued. Failure to follow applicable regulatory requirements will have a materially negative impact on the business of the Company. Furthermore, future changes in legislation cannot be predicted and could irreparably harm the business of the Company.

**Intellectual Property Rights**

The Company could be adversely affected if it does not adequately protect its intellectual property rights. The Company regards its marks, rights, and trade secrets and other intellectual property rights as critical to its success. To protect its investments and the Company's rights in these various intellectual properties, it may rely on a combination of patents, trademark and copyright law, trade secret protection and confidentiality agreements and other contractual arrangements with its employees, clients, strategic partners, acquisition targets and others to protect proprietary rights. There can be no assurance that the steps taken by the Company to protect proprietary rights will be adequate or that third parties will not infringe or misappropriate the Company's copyrights, trademarks and similar proprietary rights, or that the Company will be able to detect unauthorized use and take appropriate steps to enforce rights. In addition, although the Company believes that its proprietary rights do not infringe on the intellectual property rights of others, there can be no assurance that other parties will not assert infringement claims against the Company. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

The Company will rely on trade secrets to protect technology where it does not believe patent protection is appropriate or obtainable. Trade secrets are difficult to protect. While commercially reasonable efforts to protect trade secrets will be used, strategic partners, employees, consultants, contractors or scientific and other advisors may unintentionally or willfully disclose information to competitors.

If the Company is not able to defend patents or trade secrets, then it will not be able to exclude competitors from developing or marketing competing products, and the Company may not generate enough revenue from product sales to justify the cost of development of products and to achieve or maintain profitability.

**The results of preclinical studies or initial clinical trials are not necessarily predictive of future favorable results.**

Preclinical tests and initial clinical trials are primarily designed to test safety and to understand the side effects of drug candidates and to explore efficacy at various doses and schedules. Success in preclinical or animal studies and early clinical trials does not ensure that later large-scale efficacy trials will be successful nor does it predict final results. Favorable results in early trials may not be repeated in later ones.

**Difficulty to Forecast**

The Company must rely largely on its own market research to forecast sales as detailed forecasts are not generally obtainable from other sources at this early stage of the industry. A failure in the demand for its products to materialize as a result of competition, technological change or other factors could have a material adverse effect on the business, results of operations and financial condition of the Company.

**Litigation**

The Company may become party to litigation from time to time in the ordinary course of business which could adversely affect its business. Should any litigation in which the Company becomes involved be determined against the Company such a decision could adversely affect the Company's ability to continue operating and the market price for the Company's common shares. Even if the Company is involved in litigation and wins, litigation can redirect significant Company resources.

Commercial success of the Company will depend in part on not infringing upon the patents and proprietary rights of other parties and enforcing its own patents and proprietary rights against others. The research and development programs will be in highly competitive fields in which numerous third parties have issued patents and pending patent applications with claims closely related to the subject matter of the Company's programs. The Company is not currently aware of any litigation or other proceedings or claims by third parties that its technologies or methods infringe on their intellectual property.

While it is the practice of the Company to undertake pre-filing searches and analyses of developing technologies, it cannot guarantee that it has identified every patent or patent application that may be relevant to the research, development, or commercialization of its products. Moreover, it cannot assure that third parties will not assert valid, erroneous, or frivolous patent infringement claims.

**Uninsurable Risks**

The business of the Company may not be insurable or the insurance may not be purchased due to high cost. Should such liabilities arise, they could reduce or eliminate any future profitability and result in increasing costs and a decline in the value of the Company.

**The market price of the Company's common shares may be subject to wide price fluctuations.**

The market price of the Company's common shares may be subject to wide fluctuations in response to many factors, including variations in the operating results of the Company and its subsidiaries, divergence in financial results from analysts' expectations, changes in earnings estimates by stock market analysts, changes in the business prospects for the Company and its subsidiaries, general economic conditions, legislative changes, and other events and factors outside of the Company's control. In addition, stock markets have from time-to-time experienced extreme price and volume fluctuations, which, as well as general economic and political conditions, could adversely affect the market price for the Company's common shares.

**Dividends**

The Company has no earnings or dividend record and does not anticipate paying any dividends on the common shares in the foreseeable future.

**Dilution**

The financial risk of the Company's future activities will be borne to a significant degree by purchasers of the common shares. If the Company issues common shares from its treasury for financing purposes, control of the Company may change and purchasers may suffer additional dilution.

**Rapid Technological Change**

The business of the Company is subject to rapid technological changes. Failure to keep up with such changes may adversely affect the business of the Company. The Company is subject to the risks of companies operating in the medical and healthcare business. The market in which the Company competes is characterized by rapidly changing technology, evolving industry standards, frequent new service and product announcements, introductions and enhancements and changing customer demands. As a result, an investment in the stocks of the Company is highly speculative and is only suitable for investors who recognize the high risks involved and can afford a total loss of investment.

**Risks Associated with Acquisitions**

If appropriate opportunities present themselves, the Company may acquire businesses, technologies, services or products that the Company believes are strategic. The Company currently has no understandings, commitments or agreements with respect to any other material acquisition and no other material acquisition is currently being pursued. There can be no assurance that the Company will be able to identify, negotiate or finance future acquisitions successfully, or to integrate such acquisitions with its current business. The process of integrating an acquired business, technology, service or product into the Company may result in unforeseen operating difficulties and expenditures and may absorb significant management attention that would otherwise be available for ongoing development of the Company's business. Future acquisitions could result in potentially dilutive issuances of equity securities, the incurrence of debt, contingent liabilities and/or amortization expenses related to goodwill and other intangible assets, which could materially adversely affect the Company's business, results of operations and financial condition. Any such future acquisitions of other businesses, technologies, services or products might require the Company to obtain additional equity or debt financing, which might not be available on terms favorable to the Company, or at all, and such financing, if available, might be dilutive.

**Economic Environment**

The Company's operations could be affected by the economic context should the unemployment level, interest rates or inflation reach levels that influence consumer trends and consequently, impact the Company's future sales and profitability.

**Global Economy Risk**

The ongoing economic problems and downturn of global capital markets has generally made the raising of capital by equity or debt financing more difficult. Access to financing has been negatively impacted by the ongoing global economic risks. As such, the Company is subject to liquidity risks in meeting its development and future operating cost requirements in instances where cash positions are unable to be maintained or appropriate financing is unavailable. These factors may impact the Company's ability to raise equity or obtain loans and other credit facilities in the future and on terms favorable to the Company. If uncertain market conditions persist, the Company's ability to raise capital could be jeopardized, which could have an adverse impact on the Company's operations and the trading price of the Company's Shares on the stock exchange.

**Going-Concern Risk**

The Company's future operations are dependent upon the identification and successful completion of equity or debt financing and the achievement of profitable operations at an indeterminate time in the future. There can be no assurances that the Company will be successful in completing an equity or debt financing or in achieving profitability.

**Financial Risk Exposures**

The Company may have financial risk exposure to varying degrees relating to the currency of each of the countries where it operates and has financial risk exposure towards digital currencies. The level of the financial risk exposure related to a currency and exchange rate fluctuations will depend on the Company's ability to hedge such risk or use another protection mechanism.

**Attracting and keeping senior management and key scientific personnel**

The success of the Company depends on the continued ability to attract, retain, and motivate highly qualified management, clinical, and scientific personnel and to develop and maintain important relationships with leading academic institutions, companies, and thought leaders. Allen Davidoff, the Company's Chief Executive Officer and Director, exercises significant control over the day-to-day affairs of the Company. The Company depends on Dr. Davidoff to engage with third parties and contractors to operate the business.

**Segment Reporting**

We view our operations and manage our business in one segment, which is the development and commercialization of bio-pharmaceuticals, initially focused on the treatment of progressive kidney disease.

**Trend Information**

Other than as disclosed elsewhere we are not aware of any trends, uncertainties, demands, commitments, or events that are reasonably likely to have a material effect on our net revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information not necessarily to be indicative of future operating results or financial condition.

**Management's Responsibility for Financial Statements**

The Company's management is responsible for presentation and preparation of the financial statements and the MD&A. The MD&A have been prepared in accordance with the requirements of securities regulators, including National Instrument 51-102 of the Canadian Securities Administrators.

The financial statements and information in the MD&A necessarily include amounts based on informed judgments and estimates of the expected effects of current events and transactions with appropriate consideration to materiality. In addition, in preparing the financial information, we must interpret the requirements described above, make determinations as to the relevancy of information included, and make estimates and assumptions that affect reported information. The MD&A also includes information regarding the impact of current transactions and events, sources of liquidity and capital resources, operating trends, risks and uncertainties. Actual results in the future may differ materially from our present assessment of this information because future events and circumstances may not occur as anticipated.
