- The
company has announced an increase in the potency of its lead immunotherapy
candidate, Bria-IMT, through cryopreservation
- The
frozen formula simplifies logistics and makes it possible for the
immunotherapy to reach patients across long distances without a compromise
in the safety or efficiency of the treatment
- The
same cryopreservation approach will be utilized in the case of Bria-OTS,
BriaCell’s off-the-shelf personalized immunotherapy for advanced breast
cancer
The use of a novel Bria-IMT frozen formulation is one of the
exciting new developments that BriaCell Therapeutics Corp. (OTCQB: BCTXF) (TSX.V: BCT) announced
recently. Bria-IMT is the company’s lead immunotherapy candidate. It is a novel
treatment that works by providing breast cancer antigens that directly
stimulate T-cell activity and boost the immune system’s cancer-fighting
capabilities in advanced breast cancer patients.
According to BriaCell President and CEO Dr. William
Williams, the freezing of Bria-IMT in a viable form through the use of
well-established cryopreservation technologies enables the creation of a much
more potent immunotherapy than the previous version. Apart from resulting in a
more powerful formulation, the cryopreservation of Bria-IMT also enables easier
management of logistics processes that make the delivery of the immunotherapy
to breast cancer patients possible. Because of the combined benefits, the
development of the frozen formulation can be considered a big plus for the
program, and it will be the one that BriaCell will be using going forward,
Williams said in an interview (http://ibn.fm/KSPa5).
Cryopreservation simplifies the storage of ready-to-inject
Bria-IMT. Once delivered to a clinical facility, the formulation will simply
need to be thawed prior to patient administration. In the long run, this frozen
formulation is expected to reduce the per-dose cost in comparison to the old
Bria-IMT delivery and administration model.
Williams explained in a news release that preparation of
Bria-IMT through the previous approach was cumbersome and complex. Through
cryopreservation, the viability of the formulation is better preserved than
that of the previous version. Bria-IMT can be transported to distant locations
in its frozen state, without any compromise in its safety or effectiveness.
The new frozen formulation technology is also applicable to
Bria-OTS – BriaCell’s off-the-shelf personalized immunotherapy for advanced
breast cancer. Bria-OTS is currently being developed and is expected to enter
the clinic in the latter half of 2019.
Information about the new formulation and additional
findings pertaining to the Bria-IMT clinical trials are expected to be
announced during several industry events over the course of 2019.
BriaCell Therapeutics Corp. Founder and Director Dr. Charles
L. Wiseman will be a keynote speaker at the 10th Euro Breast Cancer Summit,
which will take place in Paris on March 21-22, 2019. The summit’s theme for
2019 is rediscovering novel approaches toward a cure for breast cancer and
women’s health (http://ibn.fm/zbzMJ).
BriaCell Therapeutics Corp. will also be presenting a poster
at the prestigious American Association of Cancer Research’s (“AACR”) annual
meeting that will be taking place from March 29 to April 3, 2019, in Atlanta,
Georgia.
These presentations will summarize results and comprehensive
data analysis of the completed phase I/IIa monotherapy trial of Bria-IMT in
advanced breast cancer. The monotherapy study involved 23 advanced breast
cancer patients. So far, Bria-IMT’s safety has been established, and the lead
candidate has achieved proof of concept in terms of expected efficacy in
certain patient populations.
