Notes to the interim condensed consolidated financial statements (unaudited)

For the Three and Nine months ended December 31, 2022 and 2021

(Tabular amounts expressed in thousands of Canadian Dollars, except for share and per share amounts)

 

 

 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Nature of business and liquidity

The Company's principal business activity is the development and commercialization of IL-2, IL-4 and IL-13 Superkines and Empowered Superkines for the treatment of cancer, inflammation and immune-mediated diseases. Medicenna has four wholly owned subsidiaries, Medicenna Therapeutics Inc. ("MTI") (British Columbia), Medicenna Biopharma Inc. ("MBI") (Delaware), Medicenna Biopharma Inc. ("MBIBC") (British Columbia) and Medicenna Australia PTY Ltd ("MAL") (Australia). Medicenna is traded on both the Toronto Stock Exchange and the Nasdaq Capital Market ("Nasdaq") under the symbol ''MDNA".

Aa at December 31, 2022, the head and registered office is located at 2 Bloor St W, 7th Floor, Toronto, Ontario, Canada.

Since inception, the Company has devoted its resources to funding R&D programs, including securing intellectual property rights and licenses, conducting discovery research, manufacturing drug supplies, initiating preclinical and clinical studies, submitting regulatory dossiers and providing administrative support to R&D activities, which has resulted in an accumulated deficit of $77.1 million as of December 31, 2022. With current finance income only consisting of interest earned on excess cash, cash equivalents and marketable securities, losses are expected to continue while the Company's R&D programs are advanced.

We currently do not earn any revenues from our product candidates and are therefore considered to be in the development stage. As required, the Company will continue to finance its operations through the sale of equity or pursue non-dilutive funding sources available to the Company in the future. The continuation of our research and development activities for MDNA55, MDNA11 and the BiSKITs<sup>TM</sup> platform and the commercialization of MDNA55 is dependent upon our ability to successfully finance and complete our research and development programs through a combination of equity financing and revenues from strategic partners. We have no current sources of revenues from strategic partners.

Management has forecasted that the Company's current level of cash will be sufficient to execute its current planned expenditures into Q2 of calendar 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Basis of presentation and significant accounting policies

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*a)* *Statement of compliance* 

These interim condensed consolidated financial statements have been prepared in accordance with International Accounting Standards ("IAS") 34 'Interim Financial Reporting' (IAS 34) using accounting policies consistent with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and the Interpretations of the International Financial Reporting and Interpretations Committee ("IFRIC").

The interim condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the Company's audited financial statements for the year ended March 31, 2022.

The interim condensed consolidated financial statements were approved by the Company's Board of Directors and authorized for issue on February 6, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*b)* *Functional and presentation currency* 

The functional currency of an entity and its subsidiary is the currency of the primary economic environment in which the entity operates. The functional currency of the parent company is the Canadian dollar and the functional currency of MBI is the US dollar, the functional currency of MTI and MBI BC is the Canadian dollar, the functional currency of MAL is the Australian dollar, and the presentation currency of the parent company is the Canadian dollar.

(Tabular amounts expressed in thousands of Canadian Dollars, except for share and per share amounts)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Basis of presentation and significant accounting policies cont'd

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*c)* *Significant accounting judgments, estimates and assumptions* 

The preparation of these unaudited interim condensed consolidated financial statements in accordance with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and reported amounts of assets and liabilities at the date of the unaudited condensed consolidated interim financial statements and reported amounts of revenues and expenses during the reporting period. Actual outcomes could differ from these estimates*.*

 

The unaudited interim condensed consolidated financial statements include estimates, which, by their nature, are uncertain. The impacts of such estimates are pervasive throughout the unaudited interim condensed consolidated financial statements and may require accounting adjustments based on future occurrences. The estimates and underlying assumptions are reviewed on a regular basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected.

The accompanying unaudited interim condensed consolidated financial statements are prepared in accordance with IFRS and follow the same accounting policies and methods of application as the audited consolidated financial statements of the Company for the year ended March 31, 2022. They do not include all of the information and disclosures required by IFRS for annual financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included in these unaudited condensed consolidated interim financial statements. Operating results for the nine months ended December 31, 2022, are not necessarily indicative of the results that may be expected for the full year ended March 31, 2023. For further information, see the Company's audited consolidated financial statements including notes thereto for the year ended March 31, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*d)* *Warrant derivative* 

When a warrant exercise price is denominated in a currency which differs from the Company's functional currency, the financial instruments are treated as liabilities and measured at fair value. The fair value of the warrants are calculated using the black-scholes model. The change in the liability has been recorded in the interim condensed consolidated statement of loss and comprehensive loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*e)* *COVID-19 Pandemic* 

 

The COVID-19 pandemic continues to cause significant financial market and social disruption. The Company cannot presently predict the scope and severity of any potential business shutdowns or disruptions related to COVID-19, the impact of any new variants nor the impact of the vaccines that are now accessible. If the Company or any of the third parties with whom it engages, were to experience shutdowns or other business disruptions due to the pandemic, its ability to conduct its business in the manner and on the timelines presently planned could be materially and negatively impacted. The Company will continue to monitor developments of the pandemic and continuously assess its potential further impact on its operations to prevent any disruptions to the conduct of its business and clinical trials. In the event of a prolonged continuation of the pandemic, it is not clear what the potential impact may be on the Company's business, financial position and financial performance.

*August 2022 Public Offering*

 

On August 10, 2022, pursuant to an underwritten public offering, 13,333,334 units were sold at a purchase price of US$1.50 per unit for gross proceeds of US$20.0 million ($25.6 million). Each unit included one common share with a fair value of US$1.06 and one common share purchase warrant with a fair value of US$0.44 (see Note 6). Each common share purchase warrant entitles the holder to purchase one common share at an exercise price of US$1.85 until August 9, 2027. We incurred transaction costs of $2.2 million (US1.7 million) of which $1.6 million (US$1.2 million) were allocated to share issue costs and $0.6 million (US$0.5 million) were allocated to operating expenses, based on their relative fair values.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Share capital cont'd** 

*At-The-Market Facility*

On December 30, 2020, the Company entered into a sales agreement with SVB Leerink acting as sales agent, pursuant to which the Company may, from time to time sell, through at-the-market ("ATM") on the NASDAQ such number of common shares as would have an aggregate offering price of up to US$25.0 million (the ATM Offering), which expired December 30, 2022.

During the nine months ended December 31, 2022, the Company issued 656,656 common shares (December 31, 2021 – 1,671,995) for gross proceeds of US$0.8 million (December 31, 2021 - US$2.9 million) at an average price of US$1.20 (December 31, 2021 - US$1.76). The Company received; net of commissions US$0.7 million (December 31, 2021 - US$2.8 million). In total, we incurred share issuance costs (including commissions) of US$0.1 million (December 31, 2021 - US$0.1 million).

**Calculation of loss per share**

Loss per common share is calculated using the weighted average number of common shares outstanding. For the three and nine ended December 31, 2022, and 2021, the calculation was as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three months ended**<br> **December 31,** | **Three months ended**<br> **December 31,** | **Nine months ended**<br> **December 31,** | **Nine months ended**<br> **December 31,** |
| | **2022** | 2021 | **2022** | 2021 |
| Common shares issued and outstanding, beginning of year | **69637469** | 53843785 | **55647479** | 53547709 |
| ATM issuances | **-** | 135453 | **600210** | 135453 |
| Shares issued on 2022 Public Offering | **-** |  | **6884848** |  |
| Effect of warrants and options exercised | **-** | 16462 | **-** | 181410 |
| **Weighted average shares outstanding, end of period** | **69637469** | 53995700 | **63132537** | 53864572 |

---

The effect of any potential exercise of the Company's stock options and warrants outstanding during the year has been excluded from the calculation of diluted loss per common share as it would be anti- dilutive.

On August 10, 2022, pursuant to an underwritten public offering, 13,333,334 units were sold at a purchase price of US$1.50 per unit for gross proceeds of US$20.0 million ($25.6 million). Each unit included one common share and one common share purchase warrant. Each common share purchase warrant entitles the holder to purchase one common share at an exercise price of US$1.85 until August 9, 2027. We incurred transaction costs of $2.2 million (US$1.7 million) of which $1.6 million (US$1.2 million) were allocated to share issue costs and $0.6 million (US$0.5 million) were allocated to operating expenses, based on their relative fair values.

Under IFRS 9 Financial Instruments and IAS 32 Financial Instruments: Presentation, warrants with an exercise price denominated in a currency that differs from an entity's functional currency are treated as a derivative measured at fair value with subsequent changes in fair value accounted for through the consolidated statement of loss. Our warrants with an exercise price of US$1.85 meet this requirement and we have presented the value of these warrants as a non-current liability on the consolidated statement of financial position. Upon exercise, the recorded liability will be included in our share capital along with the proceeds from the exercise. If these warrants expire, the related liability is reversed through the consolidated statement of loss. There is no cash flow impact as a result of the accounting treatment for changes in the fair value of the warrant derivative or when warrants expire unexercised.

Estimating the fair value for our warrant derivative requires determining the most appropriate valuation model which is dependent on the terms and conditions of the issuance. This estimate also requires determining the most appropriate inputs to the valuation model, including the expected life of the warrant derivative, expected share price volatility and expected dividend yield and making assumptions about them.

We use historical data to estimate the expected dividend yield and expected volatility of our stock in determining the fair value of the warrants. The risk-free interest rate is based on U.S. Department of Treasury benchmark treasury yield rates in effect at the time of valuation and the expected life of the warrants represents the estimated length of time the warrants are expected to remain outstanding.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.** **Government assistance cont'd** 

Of the US$14.1 million grant approved by CPRIT, Medicenna had received US$14.1 million from CPRIT at March 31, 2022.

Under the terms of the grant, the Company is required to pay a royalty to CPRIT, comprised of 3-5% of revenues on net sales of MDNA55 until aggregate royalty payments equal 400% of the grant funds received at which time the ongoing royalty will be 0.5% of revenues. At this time the royalty is not probable and therefore no liability has been recorded. In addition, the Company must maintain a presence in Texas for three years following completion of the grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8.** **Commitments** 

*Intellectual property*

 

On August 21, 2015, the Company exercised its right to enter into two license agreements (the "Stanford License Agreements") with the Board of Trustees of the Leland Stanford Junior University ("Stanford"). In connection with this licensing agreement, the Company issued 649,999 common shares with a value of $0.1 million to Stanford and affiliated inventors. The value of these shares has been recorded as an intangible asset that is being amortized over the life of the underlying patents. As at December 31, 2022, the Company's intangible assets have a remaining capitalized net book value of $62 thousand (March 31, 2022 - $65 thousand).

The Company has entered into various license agreements with respect to accessing patented technology. In order to maintain these agreements, the Company is obligated to pay certain costs based on timing or certain milestones within the agreements, the timing of which is uncertain. These costs include ongoing license fees, patent prosecution and maintenance costs, royalty and other milestone payments. As at December 31, 2022, the Company is obligated to pay the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Given the current development plans and expected timelines of the Company it is assumed that project
milestones of US$0.3 million will be due in the next five years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Project milestone payments, assuming continued success in the development programs, of uncertain timing
totaling US$2.0 million and an additional US$2.0 million in sales milestones.

The forward-looking information in this MD&A does not include a full assessment or reflection of the impacts of the COVID-19 pandemic. The continued evolution of COVID-19 and its variants, as well as periodic spikes in infection rates and local outbreaks, in spite of safety measures or vaccinations, could cause disruptions to our operations or those of third parties with whom we engage. The COVID-19 pandemic has led to global supply chain challenges, which could adversely impact our ability to conduct business in the manner and timelines presently planned. As new variants of the virus appear, especially variants that are more easily spread, cause more serious outcomes, or are resistant to existing vaccines, new health orders and safety protocols could further impact our operations. The Company will continue to monitor developments of the pandemic and continuously assess its potential further impact on its operations to prevent any disruptions to the conduct of its business and clinical trials. In the event of a prolonged continuation of the pandemic, it is not clear what the potential impact may be on the Company's business, financial position and financial performance.

All forward-looking statements reflect the Company's beliefs and assumptions based on information available at the time the assumption was made.

Although the forward-looking statements contained in this MD&A are based upon what the Company's management believes to be reasonable assumptions, the Company cannot assure readers that actual results will be consistent with these forward-looking statements.

Any forward-looking statements represent the Company's estimates only as of the date of this MD&A and should not be relied upon as representing the Company's estimates as of any subsequent date. The Company undertakes no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events, except as may be required by securities laws.

**COMPANY OVERVIEW** 

The Company's principal business activity is the development and commercialization of Superkines and Empowered Superkines for the treatment of cancer, inflammation and immune-mediated diseases. Medicenna has four wholly owned subsidiaries, Medicenna Therapeutics Inc. (British Columbia), Medicenna Biopharma Inc. (Delaware), Medicenna Biopharma Inc. (British Columbia) and Medicenna Australia PTY Ltd (Australia). On November 13, 2017, Medicenna continued under the *Canada Business Corporations Act*. On August 24, 2020, Medicenna began trading on the Nasdaq Capital Market ("Nasdaq") under the symbol "MDNA.

Medicenna is an immunotherapy company developing novel, highly selective versions of interleukin-2 ("IL-2"), interleukin-4 ("IL-4") and interleukin-13 ("IL-13") tunable cytokines, called "Superkines". These Superkines can be developed either on their own as short or long-acting therapeutics or fused with cell killing proteins to generate Empowered Superkines that precisely deliver potent payloads to cancer cells without harming adjacent healthy cells. Superkines can also be fused with a large variety of proteins, antibodies and even other Superkines to incorporate two synergistic therapeutic activities into one molecule, creating novel <u>Bi</u>-Functional <u>S</u>uper<u>K</u>ine <u>I</u>mmuno<u>T</u>herapie<u>s</u> referred to by Medicenna as BiSKITs<sup>TM</sup>. Medicenna's mission is to become the leader in the development and commercialization of Superkines, Empowered Superkines and BiSKITsä for the treatment of a broad range of cancers and other diseases. The Company seeks to achieve its goals by drawing on its expertise, and that of world-class collaborators and advisors, to develop Revolutionary Medicines using Evolutionary Superkines. Compared to naturally occurring cytokines – that bind to multiple receptors on many cell types – Superkines are engineered with unique selectivity toward specific receptor subtypes and defined target cell subsets to precisely activate or inhibit relevant signalling pathways or immune cells in order to improve therapeutic efficacy and safety.

Medicenna has built diverse platforms, each comprised of a pipeline of Superkine candidates in-licensed from Leland Stanford Junior University ("Stanford"). This includes the MDNA109 platform that consists of IL-2 agonists, IL-2 antagonists and partial agonists of IL-2. Additional assets from Stanford also include several super-agonists of IL-4 and IL-13 and dual IL-4/IL-13 antagonists. In addition, Medicenna has also independently developed therapeutic agents based on its Empowered Superkine and BiSKITsä platforms.

The most advanced of these programs is the MDNA109 platform which is a genetically engineered IL-2 Superkine designed to specifically bind to CD122 (IL-2Rβ) with high affinity. To further enhance its selectivity, two additional mutations (FEAA) were incorporated in MDNA109 to abolish binding to CD25. To improve the PK properties of the highly selective version of MDNA109 (MDNA109FEAA), it was genetically fused to protein scaffolds such as the Fc domain of IgG1 (MDNA19) or human albumin (MDNA11) effectively increasing the size of the Superkine and improving its half-life to avoid frequent daily dosing required for Proleukinâ.

We believe that, unlike Proleukinâ, both MDNA11 and MDNA19, have superior PK properties, lack CD25 binding to improve safety and reduce immune suppression, potently stimulate effector T cells, reverse natural killer ("NK") cell exhaustion and act with exceptional synergy when combined with checkpoint inhibitors.

Although MDNA19 was initially identified as the Company's lead IL-2 candidate, a pilot non-human primate study comparing MDNA11 with MDNA19 demonstrated that the former had better PK and PD features. Medicenna is therefore advancing the clinical development of MDNA11 as it is a more promising molecule and has been selected as the lead IL-2 Superkine candidate. Medicenna initiated the Phase 1/2 ABILITY Study (<u>A B</u>eta-only <u>IL</u>-2 Immuno<u>T</u>herap<u>Y</u> Study) with MDNA11 (the "ABILITY Study") in the third calendar quarter of 2021. MDNA19 remains relevant for Medicenna as it provides unique design features in the development of our BiSKITs<sup>TM</sup> platform. Our BiSKITs<sup>TM</sup> platform allows us to develop designer Superkines by fusing them to other proteins, antibodies, cytokines or other Superkines resulting in two distinct but synergistic functions into one molecule: a BiSKIT<sup>TM</sup>.

Complementing our Superkine platform is bizaxofusp (formerly MDNA55), Medicenna's Empowered Superkine, for the treatment of recurrent glioblastoma ("rGBM"), the most common and uniformly fatal form of brain cancer. Bizaxofusp is a fusion of a circularly permuted version of IL-4, fused to a potent fragment of the bacterial toxin, Pseudomonas exotoxin ("PE"), and is designed to preferentially target tumor cells that over-express the interleukin 4 receptor ("IL-4R"). Bizaxofusp has been studied in five clinical trials in 132 patients, including 112 patients with rGBM, the results of which support our belief that it has superior efficacy when compared to the current standard of care ("SOC"). Bizaxofusp has secured Orphan Drug Status from the United States Food and Drug Administration ("FDA") and the European Medicines Agency ("EMA") as well as Fast Track Designation from the FDA for the treatment of rGBM and other types of high-grade glioma. We continue to pursue a strategic partnership to facilitate bizaxofusp's further development and commercialization.

**ACHIEVEMENTS & HIGHLIGHTS** 

The following are the achievements and highlights for the quarter ended December 31, 2022 through to the date hereof:

&nbsp;&nbsp;&nbsp;&nbsp;· On November 10, 2022, the Company announced new safety, PK, and PD data from the first four dose escalation
cohorts of the Phase 1/2 ABILITY Study of MDNA11, the Company's "beta-only" long-acting IL-2 super-agonist. The data
were featured in two posters presented at the Society for Immunotherapy of Cancer (SITC) 37th Annual Meeting, which took place from
November 8 – 12, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;· In December 2022, previously reported data from the Phase 1/2 ABILITY Study of MDNA11 were featured in
an oral presentation at the 2022 Immunotherapy Bridge Conference. The presentation, titled "*Early Results of an IL-2 Superkine (MDNA11) from the Phase 1/2 ABILITY Study in Advanced Solid Tumors* **"** was delivered by Arash Yavari , M.B.B.S., DPhil., M.R.C.P., Principal Investigator at the Radcliffe Department of Medicine, University of Oxford and Principal
Clinical Advisor to Medicenna.

&nbsp;&nbsp;&nbsp;&nbsp;· Subsequent to the quarter end, on January 5, 2023, Medicenna announced that the U.S. Patent and Trademark
Office (USPTO) has issued U.S. Patent No. 11,542,312 titled "IL-2 Superagonists in Combination with Anti-PD-1." The patent
provides intellectual property (IP) protection for methods of treating cancer with an IL-2 Superkine such as MDNA11 and a PD1 (for example,
pembrolizumab), PDL1 or CTLA-4 checkpoint inhibitor in combination, as planned in the on-going ABILITY Study, or as a single agent using
our BiSKIT™ (Bifunctional SuperKine for ImmunoTherapy) platform. The patent's term extends into at least 2039 without accounting
for any potential extensions.

&nbsp;&nbsp;&nbsp;&nbsp;· Subsequent to the quarter end, in January 2023, the full results of a single-arm Phase 2b trial of bizaxofusp
(formerly MDNA55) in patients with recurrent glioblastoma were published in the peer-reviewed journal *Neuro-Oncology.* Results showed
the trial met its primary endpoint, with median overall survival (mOS) in the primary and supportive analysis populations exceeding the
trial's pre-defined success criteria and the mOS historically achieved with currently approved therapies.

**RESEARCH & DEVELOPMENT UPDATE**

**<u>Superkine Platform</u>**

**<u>MDNA11</u>**

On September 14, 2021, we announced that we had dosed the first patient in a Phase 1/2 clinical study of MDNA11. Medicenna's Phase 1/2 ABILITY Study is designed to assess the safety, PK, PD, and anti-tumor activity of various doses of MDNA11 administered intravenously every two weeks, in patients with advanced solid tumors. The basket, dose finding study includes a dose escalation phase followed by a dose expansion phase with both an MDNA11 monotherapy arm as well as a combination arm designed to evaluate MDNA11 with a checkpoint inhibitor. The study will include patients with melanoma and renal cell carcinoma where Proleukinâ is known to have clinical activity, as well as cluster of other tumor types in order to explore the pan-tumor potential of MDNA11. The study also permits alternative dosing schedules, as well as options for intra-patient dose escalation. The ABILITY Study is currently enrolling patients at clinical sites in Australia, Canada and the United States.

![](abilityschema.jpg)

On May 2, 2022, Medicenna announced new clinical data from the third cohort of the Phase 1/2 ABILITY Study of MDNA11. These data were subsequently updated in July as described below.

On May 11, 2022 , Medicenna presented additional clinical data from the Phase 1/2 ABILITY Study during a poster presentation at the 9th Annual Frontiers in Cancer Immunotherapy Meeting, organized by the New York Academy of Sciences. These data were subsequently updated in July as described below.

On July 27, 2022, Medicenna announced new clinical data on safety, PK, PD and anti-tumor activity from the Phase 1/2 ABILITY Study of MDNA11 which were presented at the Cytokine Based Drug Development Summit, held in Boston. These data were subsequently updated on September 28, 2022 and November 10, 2022 and are described below.

In the dose escalation portion of the ABILITY Study, MDNA11 is administered intravenously, as a monotherapy, once every two weeks to patients with advanced solid tumors. The trial's first two cohorts evaluated MDNA11 doses ≤ 10 µg/kg. The trial's third cohort was administered a dose of 30 µg/kg. Patients in the fourth and fifth dose escalation cohorts receive two 30 µg/kg "priming" doses of MDNA11 before stepping up to receive fixed doses of 60 and 90 µg/kg, respectively.

Key data from patients enrolled in the trial's four initial dose escalation cohorts include:

*Demographics:*

- Patients enrolled in the study to date (N=14) have failed up to four lines of prior systemic therapy.

- 11 of 14 patients have relapsed, were not tolerant to or did not respond to at least one prior immunotherapy with a checkpoint inhibitor.

 

*Safety:*

- MDNA11 treatment in Cohort 4 (comprised of two step-up doses of 30 µg/kg followed by fixed doses of 60 µg/kg every two weeks) was not associated with any dose-limiting toxicities.

- The Safety Review Committee approved dose escalation for Cohort 5 to the 90 µg/kg dose every two weeks following two priming doses at 30 µg/kg.

- Subsequent to the quarter end, the Safety Review Committee approved dose escalation for Cohort 6 to a target dose of 120 µg/kg dose every two weeks following three priming doses at 30, 60 and 90 µg/kg.

- Significant increases in eosinophil count from baseline have not been observed with MDNA11 treatment. Extremely high eosinophil count is associated with vascular leak syndrome which is a known side effect of high-dose recombinant human IL-2 (Proleukin®).

![](noevidence.jpg)

 

*Pharmacokinetics:*

- The pharmacokinetic data from the first three cohorts demonstrated similar trends following each of three repeat doses which suggests lack of immunogenicity or insignificant levels of anti-drug-antibodies.

- Dose dependent increase in the C<sub>max</sub> and Area Under the Curve were also observed.

![](pharmacodoses.jpg)

*Pharmacodynamics:*

- In addition to dose-dependent increases in lymphocyte counts and lymphocyte kinetics, MDNA11 preferentially expanded anti-cancer NK and CD8<sup>+</sup> T cells without stimulating proliferation of pro-tumor Treg cells.

![](lympexpan.jpg)

![](stimulated.jpg)

 

*Anti-tumor Activity:* 

- Of the 14 evaluable patients with at least one on-treatment imaging scan, five patients achieved tumor control (defined as stable disease, partial response, or complete response as per RECIST 1.1) during the monotherapy dose-escalation portion of the MDNA11 ABILITY Study as follows:

&nbsp;&nbsp;&nbsp;&nbsp;1. Metastatic Leiomyosarcoma Stage IV (Dose Level 2 @ 10 µg/kg); stable disease.

&nbsp;&nbsp;&nbsp;&nbsp;2. Metastatic Melanoma Grade 4C (initially enrolled at Dose Level 2 @ 10 µg/kg Q2W with subsequent
intra-patient dose escalations to Dose Level 3 @30 µg/kg and Dose Level 4 @60 µg/kg), stable disease.

&nbsp;&nbsp;&nbsp;&nbsp;3. Metastatic Sarcoma Stage IV (Dose Level 3 @ 30 µg/kg), stable disease

&nbsp;&nbsp;&nbsp;&nbsp;4. Pancreatic Ductal Adenocarcinoma (PDAC) Stage IV (Dose Level 4 @ 60 µg/kg following 2 priming doses
of 30 µg/kg), confirmed partial response.

&nbsp;&nbsp;&nbsp;&nbsp;5. Non-clear cell 3L renal cell carcinoma patient (Dose
Level 4 @ 60 µg/kg following 2 priming doses of 30 µg/kg), stable disease.

![](treat.jpg)

On September 13, 2022 we announced that we had entered into a Clinical Trial Collaboration and Supply Agreement ("CTCSA") with Merck (known as MSD outside the United States and Canada) to evaluate MDNA11 in combination with KEYTRUDA<sup>®</sup> (pembrolizumab), Merck's anti-PD-1 (programmed death receptor-1) therapy, in the ongoing Phase 1/2 ABILITY Study. Under the terms of the CTCSA, Medicenna will sponsor the study and Merck will supply KEYTRUDA<sup>®</sup>. The two companies will establish a Joint Development Committee to optimally advance the study's combination arm.

Medicenna anticipates completing the following upcoming milestones related to the MDNA11 ABILITY Study:

1) Initial PK/PD data from the ABILITY study's fifth dose escalation cohort and updated anti-tumor activity data from the first four dose escalation cohorts are expected in calendar Q1 2023.

2) Early anti-tumor activity data from the ABILITY study's sixth dose escalation cohort and single agent expansion phase (Phase 2) are expected in calendar Q3 2023.

3) Early anti-tumor activity data from the ABILITY study's combination arm are expected in calendar Q4 2023.

There has been a slight delay to milestone number 2 due to the addition of Cohort 6 to the escalation portion of the study.

**<u>BiSKITs<sup>TM</sup> (Bi-functional SuperKine ImmunoTherapies) Platform</u>**

Our BiSKITs<sup>TM</sup> platform allows us to develop designer Superkines by fusing them to other proteins, antibodies, cytokines or other Superkines to combine two distinct but synergistic functions into one molecule: a BiSKIT<sup>TM</sup>.

On April 8, 2022, we announced new preclinical data highlighting the potent anti-tumor efficacy of the next-generation BiSKIT, anti-PD1-MDNA109FEAA, in an electronic poster at the AACR Annual Meeting. BiSKITs can target cancers where other immunotherapies have failed to be effective. One example of this is MDNA223, an IL-2 Superkine fused to a checkpoint inhibitor (anti-PD1). MDNA223 is a BiSKIT designed to activate cancer killing immune cells via the IL-2 receptor while simultaneously preventing their exhaustion through the validated method of blocking PD-1 signaling. Combining these two functions into a single molecule allows us to simultaneously engage both of these important targets on the same immune cells (also known as cis-binding).

On September 22, 2022, *in vitro* data presented at Cytokines 2022 demonstrated that MDNA223's potency was similar to that of a control anti-PD1 antibody while displaying high-affinity for IL-2 receptor beta (IL-2Rβ) and no binding to IL-2 receptor alpha (IL-2Rα). This enhanced IL-2Rβ selectivity resulted in potent and preferential stimulation of anti-cancer CD8+ T cells over pro-tumor Treg cells. *In vivo* murine data showed MDNA223 exhibiting a prolonged pharmacodynamic response extending beyond the duration of pharmacokinetic exposure.

![](mdna223over.jpg)

Data from murine tumor models of colon, skin and breast cancer using a mouse version of MDNA223 (i.e MDNA223m) showed dose-dependent and statistically significant improvements in efficacy compared to co-administration of the anti-PD-1 antibody and IL-2 super-agonist (MDNA19) at equivalent molar doses, demonstrating the advantage of exploiting the BiSKIT's cis-binding potential. These data demonstrate the therapeutic synergy resulting from the BiSKIT's ability to concurrently target PD1 and the IL-2 receptor on the same immune cells (*cis*-binding approach).

![](mdna223model.jpg)

Subsequent to the quarter end, on January 5, 2023, Medicenna announced that the USPTO has issued U.S. Patent No. 11,542,312 titled "IL-2 Superagonists in Combination with Anti-PD-1." The patent provides IP protection for methods of treating cancer with an IL-2 Superkine such as MDNA11 and a PD1 (for example, pembrolizumab), PDL1 or CTLA-4 checkpoint inhibitor in combination, as planned in the on-going ABILITY Study, or as a single agent using our BiSKIT™ (Bifunctional SuperKine for ImmunoTherapy) platform. The patent's term extends into at least 2039 without accounting for any potential extensions.

Medicenna's IL-4 and IL-13 Superkines are engineered versions of wild type cytokines which possess enhanced affinity and selectivity for either the Type 1 or Type 2 IL4 receptors or dedicated IL13 receptors such as IL13Ra2. This selectivity is achieved through mutations of the IL-4 or IL-13 proteins to enhance affinity for binding to specific IL4R or IL13R subunits. Additional mutations have also been engineered to modulate their bioactivity, resulting in Superkines with enhanced signaling (super-agonists) or the ability to block signaling (super-antagonists).

On April 8, 2022, Medicenna announced new preclinical data on its long-acting IL-13 super-antagonist, Fc-MDNA413, in an electronic poster at the AACR Annual Meeting. Fc-MDNA413 is derived from Medicenna's Superkine platform and comprises of an IL-13 super-antagonist (MDNA413) fused to the Fc domain for half-life extension.

On September 22, 2022, data presented at Cytokines 2022 showed that Fc-MDNA413 blocks the IL-4 and IL-13 pathways that polarize Tumor Associated Macrophages ("TAMs") to the M2a phenotype and stimulate proliferation of Myeloid Derived Suppressor Cells ("MDSCs"). Both, TAMs and MDSCs that are known to promote cancer growth, especially in immunologically cold tumors. *In vitro* analyses showed that Fc- MDNA413 is 300-times more selective for IL-13Rα1 (over-expressed by TAMs and MDSCs) over IL-13Rα2 (a decoy receptor) compared to wild type Fc-IL13. This superior binding profile enabled Fc-MDNA413 to potently inhibit IL-4/IL-13 mediated functions as measured by blockade of pSTAT6 signaling, TF-1 cell proliferation, and M2a polarization of macrophages. In murine studies, Fc-MDNA413 demonstrated sustainable serum exposure at a dose that was well tolerated and inhibited tumor growth as a single agent in melanoma and colon cancer models. In addition, Fc-MDNA413 synergized with MDNA19 in a murine melanoma model, highlighting the advantages of co-targeting suppressive and effector immune cells within an otherwise cold tumor microenvironment.

Medicenna is currently screening and optimizing a variety of IL-2/IL-4/IL-13 Superkines as part of our BiSKITs<sup>TM</sup> platform with the goal of having a BiSKIT candidate IND-ready by the end of calendar year 2023.

**<u>Bizaxofusp (formerly MDNA55)</u>**

Bizaxofusp has been studied in five clinical trials in 132 patients, including 112 patients with rGBM, suggesting potentially superior efficacy when compared to the current SOC. The Company has secured Orphan Drug Status from the FDA and the EMA as well as Fast Track Designation from the FDA.

A Phase 2b clinical trial with bizaxofusp was completed in a multi-center, open-label, single-arm study in patients with first or second recurrence or progression of GBM after surgery or radiotherapy ± adjuvant therapy or other experimental therapies. Subsequently, a separate blinded study that collected rGBM survival and prognostic data from 81 patients, that had contemporaneously received treatment at major clinical centres using current SOC, were used to establish a matched External Control Arm ("ECA"). The blinded survival data from the matched ECA (established by matching with the bizaxofusp treated population based on 11 different prognostic factors using propensity scoring methods) were then used as a control arm versus survival data from the Phase 2b bizaxofusp trial.

On September 29, 2020, Medicenna had an End of Phase 2 (EOP2) meeting with the FDA to discuss future development and commercialization of bizaxofusp, if approved for rGBM. On October 15, 2020, we announced that the FDA agreed that we could conduct an innovative open-label hybrid Phase 3 trial that allows use of a substantial number of patients (two-thirds) from a matched ECA to support marketing authorization of bizaxofusp for rGBM. Medicenna is pursuing strategic partnerships to assist with additional clinical development of bizaxofusp, as well as preparing the program for commercialization and its subsequent launch in various countries where marketing authorization has been granted.

In January 2023, the full results of a single-arm Phase 2b trial of bizaxofusp (recently named as per WHO International Non-proprietary Names) in patients with recurrent glioblastoma were published in the peer-reviewed journal *Neuro-Oncology.* Results showed the trial met its primary endpoint, with mOS in the primary and supportive analysis populations exceeding the trial's pre-defined success criteria and the mOS historically achieved with currently approved therapies.

We have not earned revenue in any of the previous fiscal years, other than income from interest earned on our cash and cash equivalents and marketable securities.

For the nine months ended December 31, 2022, we reported a net loss of $6.2 million ($0.10 loss per share), compared to a net loss $19.4 million ($0.36 loss per share) for the nine months ended December 31, 2021. The decrease in net loss for the nine-month period ended December 31, 2022, compared with the nine-month period ended December 31, 2021, was partially as a result of decreased research and development expenditures related to the MDNA11 program, where GMP manufacturing and IND-enabling studies were completed in the prior year. There was a foreign exchange gain of $1.7 million during the nine-month period ended December 31, 2022, compared to a loss of $0.1 million in the nine months ended December 31, 2021, as a result of gain on USD cash and cash equivalents. There was a non-cash change in the fair value of the warrant derivative (gain) of $3.7 million and $5.5 million for the three and nine months ended December 31, 2022, respectively. These reductions were offset by a reimbursement of $1.8 million under the grant from CPRIT in the period ended December 31, 2021 which offset R&D expenditures in the prior year period.

For the three months ended December 31, 2022, we reported a net loss of $1.1 million ($0.02 loss per share), compared to a net loss of $4.8 million ($0.09 loss per share) for the three months ended December 31, 2021 respectively. The decrease in net loss for the three-month period ended December 31, 2022, compared with the three-month period ended December 31, 2021, was primarily due to non-cash change in the fair value of the warrant derivative (gain) of $3.7 million for the three months ended December 31, 2022.

Cash utilized in operating activities for the nine months ended December 31, 2022 was $10.4 million, compared to cash utilized in operating activities for the nine months ended December 31, 2021 of $20.7 million. The decrease in cash utilized in the nine months ended December 31, 2022 compared to the nine months ended December 31, 2021 is primarily the result of decreased research and development expenses, and unrealized foreign exchange gain.

R&D expenses of $2.9 million and $7.7 million were incurred during the three and nine months ended December 31, 2022, respectively, compared with $2.9 million and $13.5 million incurred in the three and nine months ended December 31, 2021, respectively.

The decrease in R&D expenses during the nine months ended December 31, 2022 compared to the nine months ended December 31, 2021 is primarily attributable to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· One-time higher chemistry, manufacturing and controls costs ("CMC"), associated with the first
scale-up GLP and GMP manufacturing of MDNA11 required to supply adequate drug product for IND-enabling studies and the ABILITY Study,
completed in the prior year period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Discovery and pre-clinical expenses associated with the one-time GLP compliant MDNA11 IND enabling studies,
completed in prior year period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Decrease in regulatory costs due to the preparation of regulatory filings necessary to initiate the MDNA11
ABILITY study incurred in the prior year period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Lower salary and benefits costs due to reduced headcount in the current year.

The above decreases were partially offset by an increase in clinical costs as more patients were enrolled in MDNA11 ABLILITY Study in the three and nine months ended December 31, 2022, and by the reimbursement of previously incurred expenses with respect to the CPRIT grant of $1.8 million in the nine months ended December 31, 2021.

The increase in R&D expenses during the three months ended December 31, 2022, compared to the three months ended December 31, 2021 is primarily attributable to higher clinical costs as additional patients enrolled in the MDNA11 ABILITY Study.

The above increases were partially offset by decreased discovery and pre-clinical expenses associated with the one-time GLP compliant MDNA11 IND enabling studies, decrease in regulatory costs due to the preparation of regulatory filings necessary to initiate the MDNA11 ABILITY study both completed in the prior year period.

G&A expenses of $2.0 million and $6.3 million were incurred during the three and nine months ended December 31, 2022, respectively, compared with $2.0 million and $5.8 million during the three and nine months ended December 31, 2021, respectively.

The increase in G&A expenses in the nine-month period ended December 31, 2022, compared to the nine-month period ended December 31, 2021, primarily relates to one-time transaction costs associated with the warrant derivative partially offset by a reduction in directors and officers liability insurance premiums.

The decrease in G&A expenses in the three-month period ended December 31, 2022, compared to the three-month period ended December 31, 2021, is primarily attributable to a reduction in directors and officers liability insurance premiums, partially offset by increased salary costs to support ongoing operations and finance expense on warrant amendment.

R&D expenses fluctuate quarter over quarter based on activities ongoing during that period. The higher expenditures from the quarter ended March 31, 2021 through to the quarter ended September 30, 2021 are primarily related to one-time higher CMC costs, associated with the scale-up GLP and GMP manufacturing of MDNA11 which was predominantly completed in the quarter ended September 30, 2021. Refundable tax credits of $0.7 million contributed to a decrease in R&D expenses during the quarter ended March 31, 2022. R&D expenses increased in the quarter ended December 31, 2022, as activity in the MDNA11 ABILITY study expands.

G&A expenses have remained consistent quarter over quarter, with the exception of the quarter ended September 30, 2022, which saw an increase in expenses due to one-time transaction costs associated with a warrant derivative established as part of the August 2022 public offering.

There was a non-cash change in the fair value of the warrant derivative (gain) totalling $1.8 million in the quarter ended September 30, 2022, and $3.7 million in the quarter ended December 31, 2022.

**LIQUIDITY AND CAPITAL RESOURCES**

Since inception, the Company has devoted its resources to funding R&D programs, including securing intellectual property rights and licenses, conducting discovery research, manufacturing drug supplies, initiating preclinical and clinical studies, submitting regulatory dossiers and providing administrative support to R&D activities, which has resulted in an accumulated deficit of $77.1 million as of December 31, 2022. With current revenues only consisting of interest earned on excess cash, cash equivalents and marketable securities, losses are expected to continue while the Company's R&D programs are advanced.

We currently do not earn any revenues from our product candidates and are therefore considered to be in the development stage. As required, the Company will continue to finance its operations through the sale of equity or pursue non-dilutive funding sources available to the Company in the future. The continuation of our research and development activities for bizaxofusp, MDNA11 and the BiSKITs<sup>TM</sup> platform and the commercialization of bizaxofusp is dependent upon our ability to successfully finance and complete our research and development programs through a combination of equity financing and revenues from strategic partners. We have no current sources of revenues from strategic partners.

Management has forecasted that the Company's current level of cash will be sufficient to execute its current planned expenditures for more than the next 12 months without further financing. The company's cash is expected to fund operations into calendar Q2 of 2024.

***CASH POSITION***

At December 31, 2022, we had a cash, cash equivalents and marketable securities balance of $36.2 million, compared to $20.5 million at March 31, 2022. We invest cash in excess of current operational requirements in highly rated and liquid instruments. Working capital at December 31, 2022 was $35.1 million (March 31, 2022 - $20.8 million).

On August 10, 2022, pursuant to an underwritten public offering, we sold 13,333,334 units at a purchase price of US$1.50 per unit for gross proceeds of US$20.0 million ($25.6 million). Each unit included one common share with a fair value of US$1.06 and one common share purchase warrant with a fair value of US$0.44. Each common share purchase warrant entitles the holder to purchase one common share at an exercise price of US$1.85 until August 9, 2027. We incurred transaction costs of $2.2 million (US$1.7 million) of which $1.6 million (US$1.2 million) were allocated to share issue costs and $0.6 million (US$0.5 million) were allocated to operating expenses, based on their relative fair values.

We do not expect to generate positive cash flow from operations for the foreseeable future due to additional R&D expenses, including expenses related to drug discovery, preclinical testing, clinical trials, chemistry, manufacturing and controls and operating expenses associated with supporting these activities. It is expected that negative cash flow from operations will continue until such time, if ever, that we receive marketing authorization to commercialize any of our product candidates under development and/or royalty or milestone revenue from any such products should they exceed our expenses.

**CONTRACTUAL OBLIGATIONS**

 

#### CPRIT Assistance
In February 2015, the Company received notice that it had been awarded a grant by the CPRIT whereby the Company was eligible to receive up to US$14.1 million on eligible expenditures over a three-year period related to the development of the Company's Phase 2b clinical program for bizaxofusp. As of March 31, 2022, all of the US$14.1 million had been received and the grant with CPRIT is complete.

Under the terms of the grant, the Company is required to pay a royalty to CPRIT, comprised of 3-5% of revenues on net sales of bizaxofusp until aggregate royalty payments equal 400% of the grant funds received at which time the ongoing royalty will be 0.5% of revenues. At this time the royalty is not probable and therefore no liability has been recorded. In addition, the Company must maintain a presence in Texas for three years following completion of the grant.

#### Refundable tax credits
In June 2022, the company received $0.7 million through our Australian R&D incentive program relating to the year ended March 31, 2022. The amount receivable was recorded as a reduction in research and development expenses in the year ended March 31, 2022.

***Intellectual Property***

The Company has entered into various license agreements with respect to accessing patented technology. In order to maintain these agreements, the Company is obligated to pay certain costs based on timing or certain milestones within the agreements, the timing of which is uncertain. These costs include ongoing license fees, patent prosecution and maintenance costs, royalty and other milestone payments. As at December 31, 2022, the Company is obligated to pay the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Given the current development plans and expected timelines of the Company it is assumed that project milestones
of US$0.3 million will be due in the next five years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Project milestone payments, assuming continued success in the development programs, of uncertain timing
totaling US$2.0 million and an additional US$2.0 million in sales milestones.

As part of these license agreements, the Company has committed to make certain royalty payments based on net sales to the NIH and Stanford.

***Future commitments***

As of December 31, 2022, we have the following obligations to make future payments, representing contracts and other commitments that are known and committed:

| Patent licensing costs, minimum annual royalties per license agreements | $203 | $1232 | $312 | $1747 |

---

The Company cannot reasonably estimate future royalties which may be due upon the marketing authorization of bizaxofusp or MDNA11.

As at the date of this report, we had obligations to make future payments, representing significant research and development and manufacturing contracts and other commitments that are known and committed in the amount of approximately $3.4 million, of which $2.4 million has been paid or accrued at December 31, 2022. Most of these agreements are cancellable by the Company with notice. These commitments include agreements for clinical contract research organizations, manufacturing, and preclinical studies.

**OFF-BALANCE SHEET ARRANGEMENTS** 

The Company has no material undisclosed off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on our results of operations, financial condition, revenues or expenses, liquidity, capital expenditures or capital resources that is material to investors.

This agreement expired on December 30, 2022. During the nine-month period ended December 31, 2022, the Company issued 656,656 common shares, raising total gross proceeds of $1.0 million under the ATM Facility.

**RISKS AND UNCERTAINTIES** 

The Company is an immunotherapy company that operates in a highly competitive industry that is dependent on a number of factors that include the Company's capacity to raise additional funding on reasonable terms when necessary, secure partnerships for the development of its product candidates, obtain necessary regulatory approvals and achieve market acceptance, face disruption in availability of key components for ongoing clinical studies, obtain positive results from pre-clinical and clinical studies, successfully develop existing and new products, hire and retain skilled staff and key personnel, rely on third party providers, protect its intellectual property, and face litigation risk in connection thereof. An investment in the Common Shares is subject to a number of risks and uncertainties, including the risks related to the Company being a foreign private issuer.

In addition, the Company may, from time to time, announce or publish preliminary or interim data from its clinical trials. Preliminary and interim data remains subject to audit and verification procedures that may result in the final data being materially different from the preliminary or interim data. Preliminary and interim results of a clinical trial are not necessarily predictive of final results. There can be no assurance that favorable interim or preliminary data will result in favorable final data. Preliminary and interim data are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues, patient data are further examined and reviewed, more patient data become available, and the Company prepares and issues its final clinical study report. As a result, preliminary and interim data should be viewed with caution until the final, complete data are available. Material adverse changes in the final data compared to the preliminary or interim data could significantly harm the Company's business, prospects, financial condition and results of operations.

An investor should carefully consider these risks, as well as the risks described in the Company's Annual Information Form and the Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission, as well as the other information filed with the securities regulators before investing in the Common Shares. If any of such described risks occur, or if others occur, the Company's business, financial condition and the results of operations could be seriously harmed and investors could lose all or part of their investment.

There are important risks which management believes could impact the Company's business. For information on risks and uncertainties, please also refer to the "Risk Factors" section of the Company's most recent Annual Information Form filed on SEDAR at <u>www.sedar.com</u> and included in the Annual Report on Form 20-F filed on EDGAR at www.sec.gov/edgar.

**DISCLOSURE CONTROLS AND INTERNAL CONTROL OVER FINANCIAL REPORTING** 

The Company has implemented a system of internal controls that it believes adequately protects the assets of the Company and is appropriate for the nature of its business and the size of its operations. The internal control system was designed to provide reasonable assurance that all transactions are accurately recorded, that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that our assets are safeguarded.

These internal controls include disclosure controls and procedures designed to ensure that information required to be disclosed by the Company is accumulated and communicated as appropriate to allow timely decisions regarding required disclosure.

Internal control over financial reporting means a process designed by or under the supervision of the Chief Executive Officer and the Chief Financial Officer, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS as issued by the IASB.

The internal controls are not expected to prevent and detect all misstatements due to error or fraud. There were no changes in our internal control over financial reporting that occurred during the three and nine month period ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As of December 31, 2022, the Company's management has assessed the effectiveness of our internal control over financial reporting and disclosure controls and procedures using the Committee of Sponsoring Organizations of the Treadway Commission's 2013 framework. Based on their evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that these controls and procedures are effective.

TORONTO and HOUSTON, Feb. 07, 2023 (GLOBE NEWSWIRE) -- Medicenna Therapeutics Corp. ("Medicenna" or "the Company") (NASDAQ: MDNA TSX: MDNA), a clinical stage immunotherapy company, today announced its financial results and operational highlights for the quarter ended December 31, 2022, and that the Phase 1/2 ABILITY study of MDNA11 has advanced to a sixth dose escalation cohort. All dollar amounts are in Canadian currency unless otherwise noted.

"Encouraged with MDNA11's tolerability profile in end-stage cancer patients together with its enduring trend demonstrating dose-dependent expansion of lymphocytes, we are pleased to advance the ABILITY study to the sixth dose escalation cohort," said Dr. Fahar Merchant, President and CEO of Medicenna. "MDNA11 has thus far functioned as intended, by displaying durable tumor control with better tolerability upon repeat dosing, showing dose-dependent increase in exposure without immunogenicity, and boosting anti-cancer immune cell expansion without pro-tumoral immune suppression. With these attributes together with early signs of anti-tumor activity, we hope to bolster MDNA11's efficacy in a select group of less advanced cancer patients at the optimum dose in ABILITY's upcoming Phase 2 monotherapy dose expansion cohort."

Program highlights for the quarter ended December 31, 2022, along with recent developments include:

**MDNA11: IL-2 Superkine Program**

Enrollment is complete in the fifth dose escalation cohort of the Phase 1/2 ABILITY study of MDNA11, with no dose-limiting toxicities, dose interruptions, dose de-escalations, or treatment discontinuations due to safety issues observed to date. Preliminary pharmacodynamic (PD) data showed enhanced stimulation of lymphocyte expansion relative to baseline in the fifth cohort compared to all prior dose escalation cohorts, demonstrating MDNA11's ability to boost immune activity may be enhanced at higher doses. Based on these findings, the trial has advanced to a sixth dose escalation cohort. Participants in the sixth dose escalation cohort will receive 30, 60, and 90 µg/kg "priming" doses of MDNA11 followed by a further step-up to a fixed 120 µg/kg dose. MDNA11 is dosed intravenously every two weeks in the ABILITY study.

In November 2022, Medicenna presented safety, pharmacokinetic (PK), and PD data from the first four (low and mid) dose escalation cohorts of the ABILITY study at the Society for Immunotherapy of Cancer (SITC) 37<sup>th</sup> Annual Meeting. Safety data indicated that MDNA11 was well tolerated with no dose limiting toxicities observed. PK data showed dose-dependent increases in exposure that were sustained with repeat dosing, suggesting there is no clinically meaningful anti-drug-antibody response to MDNA11. PD data showed dose-dependent stimulation of anti-cancer immunity, with MDNA11 preferentially stimulating the proliferation and expansion of anti-cancer CD8+ T and NK cells but not Tregs (associated with pro-tumor immune pathways) or eosinophils (associated with vascular leak syndrome, a known side effect of the only approved IL-2 therapy).

The results presented at the SITC meeting provide mechanistic support for previously reported anti-tumor activity data demonstrating MDNA11's single-agent potential in advanced solid tumors unresponsive to established treatments. These data show that five of fourteen (36%) evaluable patients in the ABILITY study's first four dose escalation cohorts achieved tumor control (partial response or stable disease), including one fourth-line metastatic pancreatic cancer patient who achieved a confirmed partial response.

In December 2022, previously reported data from the Phase 1/2 ABILITY study of MDNA11 were featured in an oral presentation at the 2022 Immunotherapy Bridge Conference. The presentation, titled "*Early Results of an IL-2 Superkine (MDNA11) from the Phase 1/2 ABILITY Study in Advanced Solid Tumors***"** was delivered by Arash Yavari, M.B.B.S., DPhil., M.R.C.P., Principal Investigator at the Radcliffe Department of Medicine, University of Oxford and Principal Clinical Advisor to Medicenna.

**Bizaxofusp (formerly MDNA55): Empowered IL-4 Superkine Program**

In January 2023, the full results of a single-arm Phase 2b trial of bizaxofusp (formerly MDNA55) in patients with recurrent glioblastoma were published in the peer-reviewed journal *Neuro-Oncology.* Results showed that the trial met its primary endpoint, with median overall survival (mOS) in the primary and supportive analysis populations exceeding the trial's pre-defined success criteria. Medicenna continues to pursue potential partnership opportunities to facilitate bizaxofusp's further development and, if approved, commercialization.

**Intellectual Property**

In January 2023, the U.S. Patent and Trademark Office issued U.S. Patent No. 11,542,312. The patent provides intellectual property protection for methods of treating cancer with an IL-2 Superkine and PD1/PDL1 or CTLA-4 checkpoint inhibitor, administered in combination or as a single agent BiSKIT™. The patent's term extends into at least 2039 without accounting for any potential extensions.

**Expected Upcoming Milestones**

Initial PK/PD data from the ABILITY study's fifth dose escalation cohort and updated anti-tumor activity data from the first four dose escalation cohorts are expected in calendar Q1 2023.

Early anti-tumor activity data from the ABILITY study's sixth dose escalation cohort and single agent expansion phase (Phase 2) are expected in calendar Q3 2023.

Early anti-tumor activity data from the ABILITY study's combination arm are expected in calendar Q4 2023.

**Financial Results**

Medicenna had cash and cash equivalents of $36.2 million at December 31, 2022. These funds are expected to provide the Company with sufficient capital to execute its current planned expenditures through the completion of the ABILITY study and through calendar Q2 2024 based on its current plans and projections.

Net loss for the quarter ended December 31, 2022, was $1.1 million, or ($0.02) per share, compared to a net loss of $4.8 million or ($0.09) per share for the quarter ended December 31, 2021. The decrease in net loss for the quarter ended December 31, 2022, compared with the quarter ended December 31, 2021, was primarily a result of a non-cash gain of $3.7 million related to the change in valuation of a non-cash warrant liability associated with the August 2022 financing.

Research and development expenses of $2.9 million were incurred during the quarter ended December 31, 2022, compared with $2.9 million incurred in the quarter ended December 31, 2021. Research and development expenses were consistent quarter over quarter.

General and administrative expenses of $2.0 million were incurred during the quarter ended December 31, 2022, compared with $2.0 million during the quarter ended December 31, 2021. General and administrative expenses were consistent quarter over quarter.

Medicenna's condensed consolidated interim financial statements for the quarter ended December 31, 2022 and the related management's discussion and analysis (MD&A) will be available on SEDAR at www.sedar.com and EDGAR at www.sec.gov.

**About Medicenna** 

Medicenna is a clinical stage immunotherapy company focused on the development of novel, highly selective versions of IL-2, IL-4 and IL-13 Superkines and first in class Empowered Superkines. Medicenna's long-acting IL-2 Superkine, MDNA11, is a next-generation IL-2 with superior CD122 (IL-2 receptor beta) binding without CD25 (IL-2 receptor alpha) affinity thereby preferentially stimulating cancer killing effector T cells and NK cells. Medicenna's early-stage BiSKITs™ program, (**Bi**functional **S**uper**K**ine **I**mmuno**T**herapies) is designed to enhance the ability of Superkines to treat immunologically "cold" tumors. Medicenna's IL-4 Empowered Superkine, bizaxofusp (formerly MDNA55), has been studied in 5 clinical trials including a Phase 2b trial for recurrent GBM, the most common and uniformly fatal form of brain cancer. Bizaxofusp has obtained Fast-Track and Orphan Drug status from the FDA and FDA/EMA, respectively.
