Forward-Looking Statements

Q3 2020 Medicenna Corporate Overview

Certain statements in this presentation are “forward-looking statements. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always using words or phrases such as “expect”, “seek”, “endeavour”, “anticipate”, “plan”, “estimate”, “believe”, “intend”, or stating that certain actions, events or results may, could, would, might or will occur or be taken, or achieved) are not statements of historical fact and may be “forward-looking statements”.

Forward-looking statements are based on expectations, estimates and projections at the time the statements are made that involve a number of risks and uncertainties which would cause actual results or events to differ materially from those presently anticipated. Forward-looking statements are based on expectations, estimates and projections at the time the statements are made and involve significant known and unknown risks, uncertainties and assumptions. A number of factors could cause actual results, performance or achievements to be materially different from any future results, performance or achievements that may be expressed or implied by such forward-looking statements. These include, but are not limited to, the risk factors discussed in the public filings made by Medicenna with the applicable securities commissions in Canada, including the Annual Information Form dated May 14, 2020. Should one or more of these risks or uncertainties materialize, or should assumptions underlying the forward-looking statements prove incorrect, actual results, performance or achievements could vary materially from those expressed or implied by the forward-looking statements contained in this document. These factors should be considered carefully and prospective investors should not place undue reliance on these forward-looking statements.

Although the forward-looking statements contained in this document are based upon what Medicenna currently believes to be reasonable assumptions, Medicenna cannot assure prospective investors that actual results, performance or achievements will be consistent with these forward-looking statements. Except as required by law, Medicenna does not have any obligation to advise any person if it becomes aware of any inaccuracy in or omission from any forward-looking statement, nor does it intend, or assume any obligation, to update or revise these forward-looking statements to reflect new events or circumstances.

MDNA55: A Dual Targeted Immunotherapy

MDNA55

Targets the IL4R expressed in brain tumors and in the tumor microenvironment (TME), but not the healthy brain

Highly Selective

Avoids collateral damage to healthy brain

Disrupts the TME

Targets IL4R positive cells in the TME, unblinding the tumor to the body’s immune system

Immune Memory Response

Anti-tumor immunity is initiated and remains active after MDNA55 is cleared

Safety Profile (n=118) shows MDNA55 is safe and well tolerated

• No deaths attributed to MDNA55

• No systemic toxicity

• No clinically significant laboratory abnormalities

• Drug-related adverse events were primarily neurological/aggravation of pre-existing neurological deficits characteristic with GBM and have generally been manageable with standard measures.

• Maximum Tolerated Dose established at 240 μg

• No evidence of a differential rate of neurological toxicities between doses of MDNA55 used in the current study (up to 240 µg) and a range of higher doses explored in previous studies (up to 900 μg)

Proleukin (hIL-2): first targeted immunotherapy

16

Improved IL-2 Variants are Needed

• Proleukin is approved for metastatic melanoma and renal cell carcinoma

• Proleukin is not efficient at binding CD122, therefore limiting activation of effector T cells and NK cells that attack tumors

• Proleukin preferentially stimulates the high-affinity receptor (CD25), causing:

• Extreme toxicity – hard to complete full course of therapy

• Treatment in Intensive Care Unit

• Frequent dosing (every 8 hours) for 9 days

Proleukin has very high affinity for CD25

Adult cynomolgus monkeys (age: 8-12 years) received 2 doses of MDNA11 by slow IV bolus 14-days apart and monitored for total of 28 days.

• Dose: 10, 30, 100, 300, and 600 mcg/kg

• One male monkey per group

• One monkey also received single dose of 300 mcg/kg MDNA19 and total of 21 days monitoring

Study measurements included

(1) Clinical observations

(2) Clinical chemistry

(3) Hematology

(4) Immune-profiling with Ki67 analysis of peripheral blood

(5) organ weights and macroscopic pathology

Sample collection also for (1) PK , (2) ADA and (3) cytokines/chemokines.

Study Design to Evaluate Safety, PK and PD Profile
