BERKELEY, Calif. and VANCOUVER, British Columbia, May 29, 2018 (GLOBE NEWSWIRE) -- BriaCell Therapeutics Corp.
("BriaCell") (TSX-V:BCT) (OTCQB:BCTXF), an immuno-oncology focused biotechnology company with a proprietary
targeted immunotherapy technology, announced today that it will publish its clinical findings in the American Society of Clinical
Oncology (ASCO) Annual Meeting Proceedings. ASCO’s Annual Meeting, taking place June 1-5, 2018 in Chicago, IL, represents the
world’s largest gathering of oncology physicians, biotechnology executives, researchers, and investment analysts to discuss
breakthrough clinical research and therapeutics in the field.
“We are very excited with our clinical findings, and are delighted that ASCO selected our abstract to be
published in their meeting proceedings," said Dr. Williams, BriaCell’s President and CEO. “The inclusion of BriaCell’s clinical
data in the proceedings of such a prestigious meeting lends important support to our hypothesis that Bria-IMT™’s unique mechanism
of action may shrink tumors in breast cancer patients who match HLA Class II molecules with Bria-IMT™. The findings also
provide a strong rationale for the development Bria-OTS™, BriaCell’s off-the-shelf personalized immunotherapy for advanced breast
cancer to match/cover over 90% of the patient population ,” Dr. Williams noted. “We are pleased to announce that we have recently
initiated treatment on 7 additional patients in the study, for a total of 13 patients to date. The study continues to enroll
rapidly and we look forward to sharing the interim data in the second half of 2018.”
BriaCell is currently conducting the Phase IIa trial (NCT03066947) with Bria-IMT™, and a rollover trial
(NCT03328026) with Bria-IMT™ in combination with other immunotherapies. For further information on the Phase IIa trials, please

The abstract summarizes the clinical data on 6 advanced breast cancer patients dosed with Bria-IMT™ in the
ongoing Phase I/IIa clinical study (NCT03066947). The clinical data showed that Bria-IMT™ treatment was safe and well-tolerated.
Most importantly, tumor volumes were significantly reduced in 2 of 6 advanced breast cancer patients who have failed a number of
prior treatments. These findings are highly significant because these 2 patients matched Bria-IMT™ in specific HLA molecules,
providing additional support for our hypothesis for the unique mechanism of action of Bria-IMT™ which sets it apart from similar
immunotherapy products, and provides the logic for further development of BriaDX™, BriaCell’s companion diagnostic test.

About BriaCell
BriaCell is an immuno-oncology focused biotechnology company developing targeted and safe approaches for the
management of cancer. Immunotherapy has come to the forefront in the fight against cancer because it uses the body's own immune
system in recognizing and selectively destroying cancer cells while leaving normal cells intact. In addition, immunotherapy is also
considered to be a more potent approach than chemotherapy, and has the potential to prevent cancer recurrence.
Bria-IMT™ (SV-BR-1-GM), the Company's lead product candidate, is derived from a specific breast cancer cell
line. It is genetically engineered to release granulocyte-macrophage colony-stimulating factor (GM-CSF), a substance that activates
the immune system. BriaCell believes that Bria-IMT™ helps the body to recognize and kill tumor cells by activating both T cells
that directly attack tumor cells, and B cells that produce anti-tumor antibodies.
The results of two previous proof-of-concept clinical trials (one with the precursor cell line not genetically
engineered to produce GM-CSF and one with Bria-IMT™) produced encouraging results in patients with advanced breast cancer. Most
notably, one patient with breast cancer that had spread to other sites (metastatic cancer) responded to Bria-IMT™ with a
substantial reduction in tumor size and volume in these sites, including sites in the breast, the lung, soft tissues, and even the
brain. BriaCell is currently conducting a Phase I/IIa clinical trial of Bria-IMT™ in patients with advanced breast cancer. In
this trial, to date, Bria-IMT™ treatment has been safe with instances of tumor reduction observed. This trial is listed in
ClinicalTrials.gov as NCT03066947. The trial is being conducted along with the co-development of BriaDX™, the Company’s companion
diagnostic test, to be able to predict the patients who will likely benefit the most from Bria-IMT™ treatments. Additionally, the
FDA recently approved a rollover combination study of Bria-IMT™ with pembrolizumab [Keytruda®; manufactured by Merck & Co., Inc.]
or ipilimumab [Yervoy®; manufactured by Bristol-Myers Squibb Company]. This study permits continuation of the Bria-IMT™ treatment
for patients in the ongoing Phase I/IIa trials who stop responding to the treatment. The rollover trial is listed in
ClinicalTrials.gov as NCT03328026.
Based on our observation of superior tumor shrinking responses in the patients who shared certain HLA types with
Bria-IMT™, BriaCell is developing Bria-OTS™, an off-the-shelf personalized Immunotherapy, for advanced breast cancer.
Bria-OTS™ includes a set of cell lines, each being similar to Bria-IMT™, which are being engineered to express various
pre-manufactured HLA types. With only 15 different HLA types, Bria-OTS™ cell line combinations are expected to cover over 90% of
the United States’ population. BriaCell expects to use BriaDX™ to determine the HLA types of patients, and subsequently select one
or two Bria-OTS™ cell lines with matching alleles to be administered to the patient. This should produce a potent and selective
immune response against the cancer of each patient while eliminating the time, expense, and complex manufacturing logistics
currently used for other personalized immunotherapies. In essence, Bria-OTS™ should provide a personalized treatment without the
need for personalized manufacturing.
BriaCell’s small molecule program includes the development of novel, selective protein kinase C delta (PKCδ)
inhibitors which have shown potent activity in a number of pre-clinical models of several different cancer indications as well as
fibrotic diseases.
