Cancer Immunotherapy BriaVax ™ (SV-BR-1-GM) Breast cancer cell line Allogeneic whole-cell vaccine secreting GM- CSF (“GVAX”). Scalable production - grows as cancer cell line in RPMI + 10% FBS. Irradiation prior to injection to prevent replication. Used in combination with cyclophosphamide, and post-treatment with interferon- α. Expected Result: Boosting the patient’s overall immune response to the tumor cells. Target Population 2 nd line use for late stage breast cancer . Potential use for early stage cancers sharing antigen(s) of vaccine cells. Potential use for non-breast cancers sharing antigen(s) of vaccine cells. Maintenance therapy for duration of disease
BriaVax TM Development Story Dr. C. L. Wiseman (left) helped pioneer chemotherapies before they BriaVax TM is a proprietary were considered a possibility. breast cancer cell vaccine expressing GM-CSF Impressive safety and efficacy data in a , preliminary Phase I clinical trial Planning Phase I/IIa testing of BriaVax TM as 2 nd line treatment for metastatic breast cancer.
Clinical Data to-date First Phase I: Used unmodified cell line + GM-CSF + cyclophosphamide N = 14 late stage, treatment-refractory breast cancer patients No significant adverse events, well tolerated Median Overall Survival = 12.1 months Second Phase I: Used GM-CSF-engineered cell line + cyclophosphamide + interferon- α N = 4 late stage, treatment-refractory (3 breast cancer, and 1 ovarian cancer) patients No significant adverse events, well tolerated Median Overall Survival = 35 months One robust responder with >90% regression during treatment , subsequent relapse (upon halting treatment) responded to re-treatment 6
Clinical Data to-date Second Phase I (using BriaVax TM ) 1 out of 4 Subjects responded with substantial tumor regression 7
Clinical Data to-date Lesion 1 Lesion 2 baseline 3 re-inoculations baseline 3 re-inoculations Lesion 3 baseline 3 re-inoculations 8
Hypothetical Mechanism of Action Tumor regression in a patient was directly related to rising levels of CD40 Ligand (CD40L), a protein that is expressed on components of the immune system including activated T cells, B cells, platelets, monocytic cells, natural killer (NK) cells, mast cells, and basophils. CD40L is known as one of the strongest stimulants of the immune system resulting in dendritic cell maturation, and rising serum levels of CD4+, CD8+, and NK cells, i.e., immune cells known for their anti-tumor activities. 9

Hypothetical Mechanism of Action: CTA Analysis Cancer Testis Antigens (CTAs): A class of cancer tissue specific antigens PRAME: The CTA expressed in some breast cancers. The PRAME is also expressed in BriaVax ™. BriaVax ™ injection may activate the patient T cells by PRAME recognition to cause tumor destruction.

Hypothetical Mechanism of Action: HLA Analysis BriaVax ™ caused a significant tumor shrinkage in one patient (Subject A002) - even at metastatic sites (Wiseman and Kharazi, Breast J 2006). HLA analysis of BriaVax ™ and peripheral blood lymphocytes from the 4 patients showed that the special responder (subject A002) had the same Major Histocompatibility Complexes (MHCs) class I (HLA-A) and class II (HLA-DRB3) alleles as BriaVax ™. This double-match may explain BriaVax ™ ‘s strong tumor destruction activities in that subject.

Hypothetical Mechanism of Action of BriaVax TM BriaVax ™ expresses several genes known for their roles in immune cells, including HLA-A and HLA-DRB3. BriaVax ™ may do one or few of the following: A. Directly act as antigen-presenting cells (APCs) B. Cross-Presentation: Dendritic cells may take up degraded BriaVax ™ and present BriaVax ™ antigens on their own MHCs to the patients T cells C. Cross-Dressing: Transfer BriaVax ™ antigens displayed on MHCs/HLAs to dendritic cells 13
Discovery of Gene Signature of BriaVax TM – Implications BriaCell discovered a pair of biomarkers (HLA alleles) present in the top- responder and BriaVax TM but not in the 3 other clinical trial subjects Implications: i. It improves our understanding of how the vaccine works, thus improving the likelihood of clinical success, and may accelerate the clinical development of BriaVax TM . ii. We plan to develop diagnostic tests to identify the top-responder (the patients for which the vaccine would work best) subgroup of patients. We plan to further validate our discovery using the patients data in the upcoming Phase I/IIa study 14
Phase I/II Open Label Clinical Trial IND Cleared by FDA in Nov 2015: Up to 24 stage-IV breast cancer patients Primary objective : Safety & tumor response Designed to amend the trial to evaluate: • Extending the dosing schedule (not limited to 6 vaccine injections) • Use in combination with other treatments • Application to earlier stage, more favorable to breast cancer patients • Application to other tumors 15
Accelerating the Clinical Development of BriaVax TM BriaDx ™ BriaVax ™ Combination therapy Companion diagnostics to boost efficacy: co-development Molecular analysis of Allogeneic tumor cell line blood and potentially + tumor samples GM-CSF secretion + Predict BriaVax ™ Cyclophosphamide responsiveness + Interferon- α Low development costs 16
