Combat Medical is committed over the next 5 years to creating its own clinical bibliography of fact based evidence supporting the BRS system in it’s fight against bladder cancer. By harnessing the powers of chemo-hyperthermia in an innovative and unique way we hope to prove beyond doubt that the BRS system in combination with Mitomycin C (40mg) can significantly reduce recurrence and progression rates in NMIBC bladder cancer.
Combat Medical is equally committed to improving outcomes without healthcare providers having to significantly alter their treatment model or adding additional resources, in fact we believe over time we will be able to reduce the overall treatment cost due to our streamlined approach and through the reduction in recurrence and progression rates.
We have demonstrated this potential in phase I trials and through its clinical use over the last 5 years. During this time Combat BRS has shown it is easy to use and is well tolerated by the patient with similar side effects to standard MMC instillations, but importantly with little impact in terms of time and effort for the healthcare professional in delivering Combat’s new HIVEC™ treatment.
Clinical hyperthermia is defined as the therapeutic use of temperature between 41°C to 44°Ca. The introduction
of thermal energy affects the cancer cells more because of their inability to manage the heat as well as healthy cellsb. MitomycinC (MMC) is stable at temperatures up to 50°Cf, but has shown to be 1.4 times more active at 43°Cc. Hyperthermia
inhibits the formation of new blood vessels (angiogenesis) by the tumour massd. At 43°C the cytotoxicity increases by 10 times, without any increase in the toxicity to the patientc. At elevated temperatures the lipid-protein cellular membrane bilayer will become more permeable, due to the unfolding (denaturing) of the cellular membrane and cytosolic proteins. These resulting in higher intracellular concentration of the chemotherapy agent. Direct effects on the DNA include; strand breaking, impaired transcription, reducing replication and cell divisiona. Thermotherapy has profound effects on the immune system resulting in increased activation of more natural killer cells (NKC) that target heat stressed cancer cells as they signal heat shock proteins on the cancer cell surfacee. The consequence is that the cancer cells actively participate in their own demise through the natural process of apoptosis.
Chemo-hyperthermia multifactorial modes of action create a strong combination effect, ensuring cancer tumours and cells are specifically targeted. Therefore hyperthermia substantially increases the effectiveness of chemotherapy compared to instillation at room temperature. The Combat BRS is the first system to allow the delivery of thermotherapy within the tight parameters necessary to optimise the delivery of chemo-hyperthermia without compromising patient safety, comfort or increasing resources required.
Based on the available body of evidence including real world experience data, the recommended protocol to achieve best results with HIVEC for Intermediate Risk patients is a 6 weekly induction treatment plus an additional 1 year maintenance for High Risk patients. The COMBAT BRS is recommended to be used at a temperature setting of 43°C for 1 hour using a 40mg dose of Mitomycin C.
