Notes to the interim condensed consolidated financial statements (unaudited)

For the Three months ended June 30, 2022 and 2021

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

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 June 30, 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 $75.1 million as of June 30, 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 MDNA55, MDNA11 and the BiSKITs^TM 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.

Subsequent to quarter end, the Company completed a financing which raised an additional US$20 million. This additional cash is expected to fund operations into Q1 of calendar 2024. For further details see Note 10.

COVID-19 Update

In March 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic and the Company continues to evaluate the COVID-19 situation and monitor any impacts or any potential impacts to the business. Medicenna has implemented health and safety measures in accordance with health officials and guidance from local government authorities. Further, the pandemic has had an impact on the Company’s third-party vendors resulting in delays in receiving components and supplies which delayed our ability to start certain studies and could result in development delays including the ongoing and planned clinical activities related to MDNA11. As the COVID-19 health crisis continues, the Company will continue to rely on guidance and recommendations from local health authorities, Health Canada and the Centers for Disease Control and Prevention to update the Company’s policies.

2.	Basis of presentation and significant accounting policies

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 August 12, 2022.

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.

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 three months ended June 30, 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.

3.	Share capital

Authorized

Unlimited common shares

Equity Issuances

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). The Company plans to use the net proceeds of the ATM offering for general corporate purposes including, but not limited to working capital expenditures, research and development expenditures, and clinical trial expenditures. During the three months ended June 30, 2022, the Company issued 656,656 common shares (June 30, 2021 – nil) for gross proceeds of US$0.8 million (June 30, 2021 - $nil) at an average price of US$1.20. The company received; net of commissions US$0.7 million (June 30, 2021 - $nil). In total, we incurred share issuance costs (including commissions) of US$0.1 million (June 30, 2021 - $nil).

Calculation of loss per share

Loss per common share is calculated using the weighted average number of common shares outstanding. For the period ended June 30, 2022 and 2021, the calculation was as follows:

	Three months ended June 30, 2022	Three months ended June 30, 2021
Common shares issued and outstanding, beginning of period	55,647,479	53,547,709
ATM issuances	486,076	—
Effect of warrants and options exercised	—	7,176
Weighted average common shares issued and outstanding, end of period	56,133,555	53,554,885

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.

6.	Government assistance

CPRIT assistance

In February 2015, the Company received notice that it had been awarded a grant by the Cancer Prevention Research Institute of Texas (“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 MDNA55. As of March 31, 2022, the grant with CPRIT was complete.

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.

Refundable Tax

In June 2022, the Company received $0.7 million through our Australian R&D incentive program relating to the year ended March 31, 2022.

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 June 30, 2022, the Company’s intangible assets have a remaining capitalized net book value of $65 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 June 30, 2022, the Company is obligated to pay the following:

•

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.

•

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.

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) (“MAL”). 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 in order 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 in order to incorporate two synergistic therapeutic activities into one molecule, creating novel Bi-Functional SuperKine ImmunoTherapies referred to by Medicenna as BiSKITs^TM. 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, in order 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 in order to precisely activate or inhibit relevant signalling pathways or immune cells in order to improve therapeutic efficacy and safety.

Medicenna has built a diverse platform, 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, 2 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 in order 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 (“NHP”) study comparing MDNA11 with MDNA19 demonstrated that the former had better PK and pharmacodynamic (“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 (A Beta-only IL-2 ImmunoTherapY 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^TMplatform. Our BiSKITs^TM platform allows us to develop designer Superkines by fusing them to other proteins, antibodies, cytokines or other Superkines in order to incorporate two distinct but synergistic functions into one molecule: a BiSKIT^TM.

Complementing our Superkine platform is MDNA55, Medicenna’s Empowered Superkine, for the treatment of recurrent glioblastoma (“rGBM”), the most common and uniformly fatal form of brain cancer. MDNA55 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”). MDNA55 has been studied in 5 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”). MDNA55 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 MDNA55’s further development and commercialization.

RESEARCH & DEVELOPMENT UPDATE

Superkine Platform

MDNA11

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 2 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.

On May 2, 2022, Medicenna announced new clinical data from the third cohort of the Phase 1/2 ABILITY Study of MDNA11. This data was 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 NYAS. This data was 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.

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.

To date, 10 of the 14 enrolled patients, including two of six patients in Cohort 4, have received at least one post-baseline scan and are evaluable for response to the investigational treatment.

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 2 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 2 weeks following two priming doses at 30 µg/kg.

Significant increases in eosinophil count from baseline were not 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®).

Pharmacokinetics:

The pharmacokinetic data from the first 3 cohorts demonstrated similar trends following each of 3 repeat doses which suggests lack of immunogenicity or insignificant levels of anti-drug-antibodies.

Dose dependent increase in the C_max and Area Under the Curve (“AUC”) were also observed.

Pharmacodynamics:

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

MDNA11 treatment potently activated anti-cancer CD8⁺ T cells as shown by increases in both CD25⁺ and ICOS⁺ CD8⁺ T cells.

Unlike IL-2, MDNA11 has not induced increases in ICOS⁺ Treg cells. ICOS⁺ Treg cells are highly immunosuppressive and associated with lack of response to high dose IL-2 immunotherapy.

Anti-tumor Activity:

Of the ten (10) evaluable patients with at least one on-treatment imaging scan, four (4) patients have 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:

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

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

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

Pancreatic Ductal Adenocarcinoma (PDAC) Stage IV (Dose Level 4 @ 60 µg/kg following 2 divided doses of 30 µg/kg), unconfirmed partial response.

As per RECIST 1.1 guidelines, the patient with PDAC in Dose Level 4 had stable disease at the 12-week scan and a further reduction in tumor size at week 16 (³ 30% relative to baseline scan) consistent with an unconfirmed partial response. The unconfirmed partial response is preliminary and subject to further review. As per protocol and RECIST 1.1, a second scan at ³ 28 days after the most recent scan is required to confirm a partial response in this patient. The preliminary data from this scan are subject to change if tumor reduction of at least ³ 30% relative to baseline scan is not maintained or a new tumor lesion is identified or the patient has clinical progression and is unable to continue the study or is unable to receive a confirmatory scan. As a result, the preliminary data from this scan are subject to change and not predictive of the final results. There can be no assurance that, upon completion of the confirmatory scan, that the patient will have a partial response. See “Risks and Uncertainties” below.

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

Fourth Dose Cohort Initial Anti-Tumor Activity Data - September 2022;

Fifth Dose Cohort Initial Anti-Tumor Activity Data - Q4-2022;

Single Agent Expansion Anti-Tumor Activity Data - Mid-2023;

Combination Study Top-Line Anti-Tumor Activity Data - 2H-2023.

BiSKITs^TM (Bi-functional SuperKine ImmunoTherapies) Platform

Our BiSKITs^TM 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^TM.

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).

Data from murine tumor models 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.

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.

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

MDNA55

MDNA55 has been studied in 5 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 MDNA55 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 MDNA55 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 MDNA55 trial.

On September 29, 2020, Medicenna had an End of Phase 2 (EOP2) meeting with the FDA to discuss future development and commercialization of MDNA55, 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 MDNA55 for rGBM. Medicenna is pursuing strategic partnerships to assist with additional clinical development of MDNA55, as well as preparing the program for commercialization and its subsequent launch in various countries where marketing authorization has been granted.

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 three months ended June 30, 2022, we reported a net loss of $4.2 million ($0.07 loss per share), compared to a net loss of $6.4 million ($0.12 loss per share) for the three months ended June 30, 2021. The decrease in net loss for the period ended June 30, 2022, compared with the period ended June 30, 2021, was primarily a result of decreased research and development expenditures related to the MDNA11 program, where GMP manufacturing and IND-enabling studies were being conducted in the prior year quarter. There was a reimbursement of $1.8 million under the grant from CPRIT in the period ended June 30, 2021 which offset R&D expenditures and no reimbursement in the current year period.

Cash utilized in operating activities for the three months ended June 30, 2022 was $2.3 million, compared to cash utilized in operating activities for the three months ended June 30, 2021 of $4.6 million. The decrease in cash utilized in the current year is primarily the result of decreased research and development expenses, and refundable tax credits of $0.7 million received in the current year quarter.

The decrease in R&D expenses during the current year period is primarily attributable to:

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.

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

Lower salary and benefits costs due to headcount reductions in the current year period.

Decrease in licensing costs, due to market research studies, completed in the prior year period.

The above decreases were partially offset by the reimbursement of previously incurred expenses with respect to the CPRIT grant of $1.8 million in the three months ended June 30, 2021, compared with $nil in the three months ended June 30, 2022.

G&A expenses of $1.9 million were incurred during the three months ended June 30, 2022, compared with $1.9 million during the three months period ended June 30, 2021.

G&A expenses have remained consistent quarter over quarter. The increase in stock based compensation in the current year period is due to timing and value of option grants, which was offset by lower public company expenses in the current year period due to favourable foreign exchange compared to prior year period.

R&D expenses fluctuate quarter over quarter based on activities ongoing during that period. During the quarter ended June 30, 2021 there was a $1.8 million reimbursement received from CPRIT which offset increased R&D expenses, primarily due to manufacturing and pre-clinical costs associated with MDNA11. The increase in expenditures from the quarter ended December 31, 2020 onwards, is primarily related to activities associated with the MDNA11 program and establishment of the BiSKITs^TM program. One-time higher CMC costs, associated with the scale-up GLP and GMP manufacturing of MDNA11 was completed in the quarter ended September 30, 2021, resulting in a decrease in R&D expenses from the quarter ended December 31, 2021 onwards. Refundable tax credits of $0.7million contributed to decreased R&D expenses during the quarter ended March 31, 2022.

G&A expenses began to increase in the quarter ended December 31, 2020, due to increased in directors and officers liability insurance premiums. Directors and officers liability insurance premiums are amortized for 2 months in the quarter ended September 30, 2020, with 3 months each subsequent quarter.

LIQUIDITY AND CAPITAL RESOURCES

The accompanying interim condensed consolidated financial statements have been prepared on a going concern basis in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). The going concern basis contemplates the realization of assets and the settlement of liabilities in the normal course of business as they come due for the foreseeable future. Management has forecasted that the Company’s current level of cash is expected to be able to fund operations into Q1 of fiscal 2024. Subsequent to quarter end, the Company completed a financing which raised an additional US$20 million. This additional cash is expected to fund operations into Q1 of calendar 2024. For further details, see Note 10 in interim condensed consolidated financial statements.

CASH POSITION

At June 30, 2022, we had a cash, cash equivalents and marketable securities balance of $19.3 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 June 30, 2022 was $17.9 million (March 31, 2022 - $20.8 million).

On December 30, 2020, we announced that we entered into the ATM Agreement with SVB Leerink acting as sales agent for our ATM offering of up to US$25.0 million. We plan to use the net proceeds of the ATM Facility for general corporate purposes including, but not limited to working capital expenditures, research and development expenditures, and clinical trial expenditures. As of June 30, 2022, a total of 3,803,613 common shares have been sold under the ATM Facility for total gross proceeds of $12.0 million (US$9.7 million). As of June 30, 2022, approximately $19.1 million (US$15.3 million) remained available under the ATM Facility.

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 MDNA55. As of March 31, 2022, all of the US$14.1 million had been received and the grant with CPRIT is complete.

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

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.

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.

As at June 30, 2022, there were approximately US$15.3 million ($19.1 million) available to use on 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 www.sedar.com 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-month period ended June 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As of June 30, 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.

Medicenna Reports First Quarter Fiscal 2023 Financial Results and Operational Highlights

-- Extended Cash Runway Into 2024 With US$20 Million Raise To Complete Phase 1/2 ABILITY Study And Advance Pipeline

-- New MDNA11 Data From Dose Escalation in ABILITY Study Shows Tumor Control In Four Of Ten Evaluable Patients Including Unconfirmed Partial Response In Pancreatic Cancer Patient

-- ABILITY Study Commences Enrolling In Its Fifth Dose Escalation Cohort With No Dose-Limiting Toxicities Reported To Date

-- Additional Clinical Results Including Tumor Control Data From Fourth And Fifth Dose Escalation Cohorts Expected During The Second Half Of Calendar 2022

-- Management Hosting Conference Call And Webcast Today At 8:30 am EDT

TORONTO and HOUSTON, Aug. 15, 2022 (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 June 30, 2022. Dollar amounts are in Canadian currency unless otherwise noted.

“We are off to a solid start in fiscal 2023 with a stronger balance sheet and promising anti-tumor activity of MDNA11 monotherapy in the ABILITY study,” said Dr. Fahar Merchant, President and CEO of Medicenna. “Whereas single agent activity with next-generation IL-2s has been elusive, we are encouraged with early signs of tumor control in patients with “immunologically cold” tumors including an unconfirmed partial response in a patient with advanced pancreatic cancer. These findings have accompanied desirable pharmacokinetic and pharmacodynamic characteristics, suggesting that MDNA11’s rational design and ‘beta-only’ binding profile are facilitating selective stimulation of anti-cancer immune cells while avoiding the liabilities associated with native IL-2 and competing IL-2 programs. We look forward to building on these preliminary data as we continue to evaluate higher doses of MDNA11 as a single agent and plan to report new data from the ABILITY study during the coming weeks and months.”

Recent Clinical Highlights

In July 2022, Medicenna presented clinical data at the Cytokine Based Drug Development Summit in Boston (“Cytokine Summit”) on safety, pharmacodynamics, and anti-tumor activity from the first four (low and mid) dose escalation cohorts of the Phase 1/2 ABILITY study of MDNA11, the Company’s long-acting IL-2 superagonist. Treatment was administered via intravenous (IV) infusion every two weeks in all dose cohorts. These data provide preliminary evidence of MDNA11’s single agent anti-tumor activity, as tumor control was achieved in four of ten evaluable patients with advanced solid tumors unresponsive to other treatments. Patients achieving tumor control included one sarcoma patient and one metastatic melanoma patient from the second dose escalation cohort (10 µg/kg dose), one sarcoma patient from the third dose escalation cohort (30 µg/kg dose), and one pancreatic cancer patient from the fourth dose escalation cohort (two 30 µg/kg “priming” doses followed by step-up to a fixed 60 µg/kg dose). An additional four patients from the fourth dose escalation cohort are awaiting their first post-baseline scan and are not yet evaluable for response to MDNA11. All fourteen patients enrolled in the ABILITY study to date failed between one to four lines of prior systemic therapy, including eleven who relapsed on, could not tolerate, or did not respond to at least one prior immunotherapy with a checkpoint inhibitor.

Following the presentation at the Cytokine Summit, a patient with pancreatic cancer had further tumor shrinkage consistent with an unconfirmed partial response (uPR). The uPR is preliminary and subject to further review. As per protocol and RECIST 1.1, a second scan at 28 days after the most recent scan is required to confirm a partial response in this patient. As a result, the preliminary data from this scan are subject to change and not predictive of the final results. There can be no assurance that, upon completion of the confirmatory scan, that the patient will have a partial response.

Pharmacodynamic data from the ABIILTY study show MDNA11 treatment leading to the preferential activation and expansion of anti-cancer immune cells (CD8⁺ T cells and natural killer cells) with limited proliferation of regulatory T cells (cause of immunosuppression) and eosinophils (cause of toxicity) typically associated with native IL-2 and “alpha-binding” IL-2 variants. In addition, MDNA11 continues to exhibit an acceptable safety profile, with no dose-limiting toxicities reported in the ABILITY study to date. The trial is currently enrolling into its fifth dose escalation cohort, which evaluates patients receiving two 30 µg/kg priming doses of MDNA11 followed by step up to a fixed dose of 90 µg/kg with each dose administered at 2 week intervals.

Expected Upcoming Milestones

Additional anti-tumor activity data from the ABILITY study’s fourth dose escalation cohort are expected in late September 2022.

Initial safety, PK, PD and anti-tumor activity data from the ABILITY study’s fifth dose escalation cohort are expected in the fourth quarter of calendar 2022.

Anti-tumor activity data from the ABILITY study’s single agent expansion phase are expected in the middle of calendar 2023.

Top-line anti-tumor activity data from the ABILITY study’s combination arm are expected in the second half of calendar 2023.

Financial Results

“We are pleased to start fiscal 2023 with a newly strengthened balance sheet from our raise of US$20 million, attracting new healthcare focused institutional investors despite the challenging capital markets, which allows us to extend our cash runway into 2024. Our increased cash position will help us to complete the Phase 1/2 ABILITY Study including the combination arm of the clinical trial and advance at least one BiSKIT candidate to IND readiness,” said Elizabeth Williams, Chief Financial Officer of Medicenna.

Medicenna had cash, cash equivalents, and marketable securities of $19.3 million at June 30, 2022, compared to $20.5 million at March 31, 2022. Subsequent to the quarter end Medicenna raised US$20 million by way of a public offering. Funds on hand as of June 30, 2022 plus those raised in the recent offering, we believe, are sufficient capital to execute the Company’s operations into calendar 2024 and through important upcoming catalysts described above.

Net loss for the quarter ended June 30 2022, was $4.2 million, or ($0.07) per share, compared to a net loss of $6.4 million, or ($0.12) per share, for the quarter ended June 30, 2021. The decrease in net loss for the quarter ended June 30, 2022, compared with the quarter ended June 30, 2021, was primarily a result of reduced research and development spending.

Research and development (R&D) expenses of $2.4 million were incurred during the quarter ended June 30, 2022, compared with $4.3 million incurred in the quarter ended June 30, 2021. The decrease in R&D expenses in the current fiscal year’s quarter is primarily attributed to costs associated with the development of MDNA11 incurred in the prior year period including, IND enabling studies and manufacturing of GMP materials for the ongoing Phase 1/2 ABILITY Study, for which no comparable expenses exist in the current year period. We expect R&D expenses to increase as we continue to advance in our product pipeline.

General and administrative (G&A) expenses of $1.9 million were incurred during the quarter ended June 30, 2022, compared with $1.9 million incurred in the quarter ended June 30, 2021. G&A expenses were consistent quarter over quarter.

Medicenna’s condensed consolidated interim financial statements for the quarter ended June 30, 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 the Phase 1/2 ABILITY Study
The ABILITY (A Beta-only IL-2 ImmunoTherapY) study is designed to assess the safety, pharmacokinetics, pharmacodynamics, and anti-tumor activity of various doses of intravenously administered MDNA11 in patients with advanced, relapsed, or refractory solid tumors. The trial includes an MDNA11 monotherapy arm, as well as a combination arm designed to evaluate MDNA11 with a checkpoint inhibitor. Approximately 80 patients are expected to be enrolled into the ABILITY study. Following establishment of the recommended Phase 2 dose (RP2D) and optimal treatment schedule in the study’s dose escalation phase, Medicenna plans to conduct a dose expansion phase that will enroll patients with renal cell carcinoma, melanoma, and other solid tumors in monotherapy and combination settings. For more information, see ClinicalTrials.gov Identifier: NCT05086692.
