Like many treatments currently under development for Covid-19,. Bonus BioGroup's product works on the hyper-inflammation mechanism in which, in late stages of the disease, the immune system becomes out of control (cytokine storm) and causes worse damage than the virus itself.
The trial, which was carried out at Rambam Hospital in Haifa, comprised ten patients. It found improvement in several health parameters the first time the treatment was administered, and further improvement as treatment continued.
The trial did not include a control group, but the parameters of each patient after treatment were compared with their highest readings. The results show that the level of inflammatory protein CRP in the patients' blood fell by 29-34%, the level of the enzyme creatinine kinase fell by 20-22%. Similar results were obtained for levels of other substances excessive levels of which in the blood indicate a severe case of Covid-19. In addition, radiographs showed a decrease in the area of diffuse lung inflammation in patients treated with MesenCure.
