The Phase II trial confirmed the final results of Stage I, which was carried out in Israel final winter and observed 29 out of 30 sufferers in reasonable to significant situation recuperate in just times.
“The principal aim of this examine was to confirm that the drug is risk-free,” Prof. Nadir Arber explained. “To this working day we have not registered any sizeable aspect impact in any affected person from the two groups.”
The demo was executed in Athens for the reason that Israel did not have ample pertinent sufferers. The principal investigator was Greece’s coronavirus commissioner, Prof. Sotiris Tsiodras.

Arber and his team, which include Dr. Shiran Shapira, designed the drug based mostly on a molecule that the professor has been learning for 25 a long time called CD24, which is normally present in the entire body.
The main result in of the scientific deterioration is an above activation of the immune system, also recognised as a cytokine storm. In situation of COVID-19 patients, the system starts attacking nutritious cells in the lungs.
“This is exactly the problem that our drug targets,” he claimed.

Arber pressured that their treatment method, EXO-CD24, does not impact the immune technique as a entire, but only targets this certain system, assisting come across all over again its right harmony.
“This is precision medicine,” he mentioned. “We are pretty joyful that we have found a resource to tackle the physiology of the disorder.”
“Steroids for instance shut down the whole immune system,” he even more described. “We are balancing the portion liable for the cytokine storms utilizing the endogenous system of the body, which means tools made available by the system by itself.”
Arber mentioned that a further breakthrough ingredient of this therapy is its shipping and delivery.
“We are utilizing exosomes, extremely smaller vesicles derived from the membrane of the cells which are dependable for the trade of data among them,” he claimed.
“By taking care of to provide them precisely wherever they are needed, we avoid several aspect results,” he additional.
The staff is now prepared to start the final section of the analyze.
“As promising as the conclusions of the very first phases of a procedure can be, no one particular can be absolutely sure of just about anything until eventually final results are when compared to the ones of people who acquire a placebo,” he stated.
Some 155 coronavirus sufferers will get component in the analyze. Two-thirds of them will be administered the drug, and a single-3rd a placebo.
The examine will be performed in Israel and it could possibly be also carried out in other places if the selection of patients in the place will not suffice.
