Developing Personalized Off-The-Shelf Immunotherapy Treatments for Cancer Patients
This BriaCell Therapeutics Corp. profile is part of a paid investor education campaign.*
At the forefront of cancer treatments, immunotherapies boost the ability of the body’s own cancer-fighting cells to destroy cancerous tumors. Immunotherapies also have low-toxicity, making it easier for patients to undergo treatment. Most importantly, they may offer better efficacy and less chance of recurrence for many cancer patients. In a report released by Research and Markets, the global immuno-oncology market is expected to reach $100 billion by 2022, and BriaCell continues to uncover opportunities in this space with its innovative technologies.
BriaCell’s lead candidate, Bria-IMT™, is an immunotherapy currently being developed to treat advanced breast cancer, which is the expected cause of approximately 43,000 deaths in the US in 2021. Bria-IMT™ recently achieved positive proof of concept, showing outstanding safety and efficacy data. Importantly, preliminary efficacy data was similar or superior to those of other approved breast cancer drugs when they were at a similar stage of clinical development.
BriaCell currently has a non-exclusive clinical trial collaboration with Incyte Corporation (NASDAQ:INCY) to evaluate the effects of combinations of novel clinical candidates. Under the agreement, Incyte and BriaCell will be evaluating novel combinations of compounds from Incyte’s development portfolio with BriaCell’s drug candidates in advanced breast cancer patients.
BriaCell has been dosing patients in a Phase I/IIa clinical trial of Bria-IMT™ in combination with the immunotherapy development candidates retifanlimab, an anti-PD-1 antibody, and is planned to also combine with epacadostat, an orally bioavailable small-molecule inhibitor of indoleamine 2,3-dioxygenase 1 (both provided by Incyte). The combination study is listed in ClinicalTrials.gov as NCT03328026.
BriaCell is also developing Bria-OTS™, an off-the-shelf personalized immunotherapy, for advanced breast cancer. Bria-OTS™ immunotherapy treatments are personalized to match the patient without the need for personalized manufacturing. Bria-OTS™, which is expected to match over 99 percent of the patient population, is designed to produce a potent and selective immune response against the cancer of each patient while eliminating the time, expense and complex manufacturing logistics associated with other personalized immunotherapies.
In November 2020, BriaCell announced a Cooperative Research and Development Agreement with the National Cancer Institute (NCI, Center for Cancer Research), part of the National Institutes of Health, to investigate novel off-the-shelf personalized therapeutics for cancer.
BriaCell’s management team is comprised of a team of experienced industry leaders involved in the approval of dozens of drugs.

The Cancer Immunotherapy Space
There are a number of challenges that cancer immunotherapy treatments face. Approved immunotherapies work in 20 to 30 percent of patients. They depend on the patient’s weakened immune system and, in some cases can cause autoimmune disease.
Other challenges include the lack of effectiveness of cancer immunotherapies to treat some solid tumors or blood cancers since they only work in certain types of cancer and not in others. Additionally, newly developed effective personalized immunotherapies such as PROVENGE® and CAR-T need to be individually manufactured for each patient. This means a complex and time-consuming manufacturing process, which is extremely expensive and might make the therapies commercially unsuccessful.
In response to these challenges, BriaCell is developing Bria-OTS™, an off-the-shelf personalized immunotherapy, for advanced breast cancer, which has been estimated to be the cause of about 43,000 deaths in the US in 2021.
The off-the-shelf approach means that the treatments are pre-manufactured and the patient will be able to receive her or his personalized, targeted treatment using an easy and common HLA test on her or his saliva sample. This approach is quick, and relatively inexpensive, and avoids the complex manufacturing process associated with other personalized immunotherapy treatments. This approach is the first of its kind for advanced breast cancer.
Bria-IMT™, BriaCell’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 stimulate cancer-fighting T-cells, cells that directly attack tumor cells, and B-cells that produce anti-tumor antibodies.

Proof-of-concept clinical trials
The first clinical trial used the original unmodified breast cancer cell line, with low dose cyclophosphamide and GM-CSF to boost the immune response. Fourteen patients were treated and produced impressive results, including no severe drug-related side-effects and a median survival rate in patients after treatment of about twice what was expected.
The second clinical trial used Bria-IMT™ (i.e. the original cell line – modified to produce GM-CSF) along with low dose cyclophosphamide and interferon-alpha in four advanced-stage cancer patients. The treatment was tolerated very well with few side effects. The median overall survival was much longer than expected. The study also had one patient that responded extremely well to the treatment with an approximately 90 percent tumor reduction in breast cancer as well as disappearance of the cancer from the lungs and soft tissues.

After the treatment stopped, as required by the study, the patient’s breast cancer returned and had spread to the patient’s brain, lungs and other sites. Importantly, the patient was treated again with Bria-IMT™ and the tumors were reduced at multiple sites, even in the brain. This patient-matched Bria-IMT™ for HLA genes which are used to match patients to tissues in tissue transplantation (e.g. for kidney transplants).
Recent clinical findings (Phase I/IIa proof-of-concept study with Bria-IMT™: 2017 to 2018)
BriaCell completed a Phase IIa study of Bria-IMT™ in advanced breast cancer in 23 patients that were heavily pre-treated (listed in ClinicalTrials.gov as NCT03066947) and released their initial data in September 2018. To date, Bria-IMT™ treatment has been safe with several instances of tumor reduction observed in certain patients sharing a key biomarker (HLA match) with Bria-IMT™. The treatment was safe and well-tolerated. Most importantly, initial efficacy data was similar or superior to those of other advanced or approved drugs for breast cancer when they were at a similar stage of clinical development.
Based on the recent findings related to the mechanism of action of Bria-IMT™, and the potential to produce intensified anti-tumor activity when used in combination with certain drugs, the company is now conducting the combination study of Bria-IMT™ with retifanlimab and epacadostat. The combination study is listed in ClinicalTrials.gov as NCT03328026.
Immune checkpoint inhibitors such as anti-PD-1 including pembrolizumab (KEYTRUDA®; manufactured by Merck & Co., Inc.) and, more recently, Incyte’s retifanlimab (under a corporate collaboration with Incyte Corporation) , are designed to neutralize immune suppression in cancer patients. The significance of immune checkpoints has been recognized by the Nobel committee by awarding Drs. Honjo and Allison with the 2018 Nobel Prize in Physiology or Medicine. BriaCell believes that Bria-IMT™ can exert additive or synergistic tumor-directed effects with checkpoint inhibitors like KEYTRUDA®. Initial safety data for the combined approach shows that it is very safe and well-tolerated by patients. Early efficacy data for the first eleven advanced breast cancer patients dosed with Bria-IMT™ in combination with KEYTRUDA® suggested strong additive or synergistic effects on tumor regression (shrinkage).
BriaCell hypothesizes that 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.
BriaCell Therapeutics’ Collaboration with Incyte Corporation
In April 2019, BriaCell and Incyte Corporation formed a non-exclusive clinical trial collaboration to evaluate the effects of combinations of novel clinical candidates. Under the agreement, Incyte and BriaCell plan to evaluate novel combinations of compounds from Incyte’s development portfolio with Bria-IMT™ in advanced breast cancer patients.
BriaCell initiated dosing patients with advanced breast cancer in its Phase I/IIa clinical study for Bria-IMT™ in combination with Incyte’s retifanlimab and epacadostat. The goal of the program is to remove cancer-induced suppression of the immune system (taking the “foot off the breaks” that cancer puts on the immune system) and stimulating an immune response with the Bria-IMT™, putting the “foot on the gas”. This is expected to allow the immune system to attack the cancer in a targeted way with the help of Bria-IMT™. The combination study is listed in ClinicalTrials.gov as NCT03328026.
BriaCell has developed a companion diagnostic test that would allow a physician to prepare a personalized pre-made treatment for each patient based on the presence of certain biomarkers (HLA type). Testing is simple and done on the patient’s saliva.
This diagnostic test may be used in future clinical trials to speed up the clinical development of Bria-IMT™ and will be used in trials of Bria-OTS™.
The Bria-OTS™ treatment is based on pre-manufactured immunotherapies – each containing a specific HLA type – which can be selectively administered to patients based on the patient’s HLA type. BriaCell is developing 15 unique HLA types that will allow for the treatment of over 99 percent of advanced-staged breast cancer patients. This approach provides customized cancer immunotherapy for each individual patient that doesn’t require personalized manufacturing.

A simple diagnostic test, BriaDX™, will determine the appropriate off-the-shelf immunotherapy for each patient. Based on the results, one or two pre-made Bria-OTS™ immunotherapy cell lines will be selected to be administered to the patient. Thus, Bria-OTS™ is expected to provide the patient with fast, inexpensive, safe and effective personalized cancer immunotherapy treatment that can be ordered readily.
BriaCell Therapeutics’ Small Molecule Program
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. Protein kinase C delta (PKCδ) inhibitors may provide another shot on goal besides a potential partnership opportunity.
