BriaCell Corporate Highlights

BriaCell Therapeutics Corp. (Nasdaq: BCTX, BCTXW; TSXV: BCT) is a clinical stage immunotherapy company developing treatments that boost the ability of the body’s own cancer-fighting cells to destroy cancerous tumors

Lead drug candidate Bria-IMT™ is targeting third-line advanced breast cancer (the cause of over 40,000 deaths per year in the U.S.) and its associated U.S. patient population of ~70,000 patients

35 patients dosed to-date show robust response Our Phase I/IIa safety & efficacy show similar or superior results to those of other advanced or approved drugs for breast cancer at similar clinical stages of development

Incyte Corporation (Nasdaq: INCY) Corporate collaboration and supply agreement

BriaCell’s Patented Immunotherapy: Bria-IMT™

7

Mechanism of Action: Specific Immune Activation directly stimulates cancer-fighting cells in advanced breast cancer

Bria-IMT™ (developed from a breast cancer cell line) is a patented (USPTO) immunotherapy approach that directly stimulates the body’s own cancer-fighting cells to attack and destroy breast cancer tumors.

We believe that Bria-IMT™:

1. Produces antigens (proteins made by breast cancer cells).

2. Further boosts the immune response through secretion of a protein called GM-CSF.

3. The antigens are ‘presented’ to CD4+ and CD8+ T-cells, cells known for tumor destruction.

4. Also directly stimulates cancer-fighting T-cells, further boosting the response.

Bria-IMT™ – Phase I/IIa Efficacy in Breast Cancer

HLA-Type Matching and Biological Activity (original patients + Phase I/IIa data)

Patient 01-002 – Two HLA Matches

Patient 01-002 was treated with the Bria-IMT™ regimen and had what we conclude was a robust response, specifically substantial tumor regression in 20 lung metastases that all either disappeared or shrunk to tiny scars.

Pre-Treatment Post-Treatment

HLA Matching Hypothesis: Tumor regression appears to be most pronounced in patients who match Bria-IMT™ at specific HLA-types & develop an immune response

4 patients treated by Dr. Wiseman in 2004-2005 (original patients), including one remarkable responder.

23 patients were dosed in 2017-2018 (Phase I/IIa), all very heavily pre-treated (with chemotherapy).

Safety & Efficacy Data: We believe the data was similar or superior to those of other advanced or approved drugs for breast cancer at similar clinical stages of development.

Mechanism of Action & Proof-of-Concept

Bria-IMT™ in Combination with Immune Checkpoint Inhibitors

9

Why did we combine Bria-IMT™ with immune checkpoint inhibitors?

• BriaCell has observed PD-L1 expression on circulating cancer cells & cancer-associated cells in >90% of our patients

• Bria-IMT™ increases the immune response, while checkpoint inhibitors decrease immune suppression

• Bria-IMT™ appears to have exerted additive or synergistic tumor-directed effects with checkpoint inhibitors

• BriaCell’s hypothesis: Checkpoint inhibitors act by "awakening" a component of the immune system, while Bria-

IMT™ "puts the foot on the gas" of the immune system, which may lead to more powerful anti-tumor activity

How Do Checkpoint Inhibitors Work?

• PD-L1 molecules block immune cells from attacking cancer cells

• Immune checkpoint inhibitors are designed to neutralize this immune suppression in cancer patients

BriaCell is currently dosing Bria-IMT™ with Incyte’s selected compounds under a corporate collaboration

Bria-IMT™ + Immune Checkpoint Inhibitor Combination Study Data

10

Phase I/IIa Combination Study in Advanced Breast Cancer

Patients were treated with the combination of Bria-IMT™ and anti-PD-1 antibody KEYTRUDA®.

An excellent safety and tolerability profile on the first 11 patients was observed.

All 11 patients were very heavily pre-treated with a median of 5 prior systemic therapy regimens (such as chemotherapy).

Most had very weak immune systems, further emphasizing the importance of the positive results observed.

As BriaCell had been purchasing the KEYTRUDA® for the study from Merck without a supply agreement, the study was switched to evaluating combination therapy with Incyte drugs and the combination with KEYTRUDA® was discontinued.

Patient HLA Match Observations Notes

1 0

25% reduction in sum of diameters of target liver metastases (breast cancer tumors in the liver).

8 prior chemotherapy or biological therapy regimens with extensive tumor growth in her liver.

Not an HLA match with Bria-IMT™ suggesting that—in combination with KEYTRUDA®—tumor reduction may occur without a match.

5 2

70% reduction in sum of diameters of target adrenal metastasis and complete resolution of orbital (behind the eye) metastasis.

Failed 12 prior regimens with 16 agents (13 chemotherapy and 3 hormonal).

Match at HLA-C and HLA-DRB3 loci.

Bria-IMT™ + Immune Checkpoint Inhibitor: Remarkable Responder

11

Complete resolution of orbital tumor in a heavily pre-treated patient with 2 HLA matches and a grade II tumor supports remarkable activity of the Bria-IMT™ combination regimen, and it is

worth noting that checkpoint inhibitors have not proven effective as monotherapy in advanced breast cancer

We believe these findings identify a patient population with higher clinical benefit rates

Breast Cancer Grade Correlates with Response Bria-IMT™ is derived from a grade II (moderately differentiated) breast cancer.

Genes expressed by Bria-IMT™ match best with grade I/II-derived Breast Cancer Cell Lines

~40% of recurrent breast cancers are grade I/II

Introducing… Bria-OTS™

Bria-OTS™: Off-The-Shelf Personalized ImmunotherapyConfirmation of “Matching Hypothesis” resulted in BriaCell’s “OTS” strategy

• Cooperative Research and Development Agreement with the National Cancer Institute, part of the National Institutes of Health

• We believe our treatment is most effective when the patient’s HLA-type matches the Bria-IMT™ HLA-type

• We are engineering 15 unique HLA types (molecules), collectively referred to as Bria-OTS™, allowing for what we believe will be matching and treatment of over 99% of patients with advanced breast cancer

• Bria-OTS™ involves a simple saliva test to determine the HLA-type of each patient• Each patient will then be treated with the appropriate pre-manufactured Bria-OTS™ formulation

• Similar cell lines in development for prostate cancer, lung cancer, and melanoma, as well as a pre-clinical Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (USA)

We anticipate each patient will be treated with a pre-manufactured formulation based on HLA-type
