reduce the cost of tailor-made immunotherapy
BriaCell Therapeutics Corp. (OTCQB: BCTXF) (TSX.V: BCT), a
biotechnology company focused on immuno-oncology, recently announced the
completion of several important milestones in 2018. These include obtaining
topline safety and efficacy data in a clinical trial, achieving proof of
concept and advancing the BriaCell clinical program.
Some of the most important information and data were
included in a comprehensive report for Frontiers of Immunology, according to
BriaCell CEO Dr. Bill Williams. The report highlights the complex mechanism in
which targeted immunotherapy helps a patient’s immune system target cancer
cells specifically.
BriaCell recently announced excellent safety and efficacy
data from a phase I/IIa proof of concept clinical study in advanced breast
cancer patients. There were reports of tumor shrinkage in various sites. These
results were confirming the findings from two previous proof-of-concept
clinical trials that showed promising results in patients with advanced breast
cancer. The most notable result was observed in a patient whose breast cancer
had metastasized. The patient responded to Bria-IMT, and substantial tumor
shrinkage occurred. Shrinkage was observed in the breast, lungs, soft tissues
and brain.
The immuno-oncology focused biotechnology company has
already initiated patient dosing in a phase I/IIa clinical trial of its
Bria-IMT, a breast cancer cell line that has been engineered to produce an
immune-activating factor, in combination with immune checkpoint inhibitors
pembrolizumab [KEYTRUDA; manufactured by Merck & Co., Inc. (NYSE: MRK)] or
ipilimumab [YERVOY; manufactured by Bristol-Myers Squibb Company (NYSE: BMY)].
The study focuses on advanced breast cancer (http://ibn.fm/thGQd).
Immune checkpoint inhibitors such as KEYTRUDA and YERVOY
boost the anti-tumor immune activity in cancer patients, and they recently came
into the spotlight when the Nobel committee decided to award Dr. Tasuku Honjo
and Dr. James P. Allison the 2018 Nobel Prize in Physiology or Medicine “for
game-changing discoveries about how to harness and manipulate the immune system
to fight cancer” (http://ibn.fm/3DZae).
In an important pre-clinical study lead by Dr. Allison, KEYTRUDA and YERVOY
significantly boosted the anti-tumor effects of an immunotherapeutic product
designed similarly to Bria-IMT (http://ibn.fm/an8s4).
Bria-IMT stimulates the activity of T-cells that play a
crucial role in the immune response. BriaCell expects KEYTRUDA and YERVOY to
further amplify the anti-tumor activity of Bria-IMT, and it hopes to offer safe
and effective treatment options to advanced breast cancer patients soon.
In addition to launching the new clinical trial, BriaCell is
also focused on creating personalized off-the-shelf immunotherapy treatments
that will eventually cover 90 percent of the patient population. According to
Williams, such an approach will potentially revolutionize cancer immunotherapy.
BriaCell is the developer of the trademarked Bria-OTS – a
personalized immunotherapy treatment for advanced breast cancer. The treatment
is tailored to match the patient without the need for the execution of a
personalized manufacturing process. The treatment produces a powerful selective
immune response against the specific cancer. The treatment reduces the amount
of time, expense and logistical processes currently required for the creation
of personalized cancer immunotherapies.
Breast cancer is the most commonly occurring form of cancer
in women and the second most common overall cancer, according to the World
Cancer Research Fund. In 2018, there have been over two million new cases
globally (http://ibn.fm/hdGX3).
Approximately 12.3 percent of women in the U.S. will receive
the diagnosis at some point in their lifetime (http://ibn.fm/U4kCo). The good
news is that the five-year survival rate for patients diagnosed with breast
cancer has improved over time, going up from 74.8 percent in 1975 to 90.7
percent for those between 2004 and 2011.
