Proof of concept

Peer Approved article about MuTaTo by Dr Morad & Dr Itzhaki

"In this paper, we present MuTaTo©, a new personalized medicine concept for curing cancer patients. In the development of this concept, we have tried to address all of the factors that cause poor success rate in cancer treatment. We have designed experiments, that would show that the principles behind MuTaTo are sustainable."

The effect of several peptides on the phosphorylation levels of human EGFR in A431 cell line was assessed by ELISA test: Exponentially growing A431 cells were seeded on a 96-well plate, and grown for about 3 days. Following medium exchange, solutions containing 50 mg/ml EGF and 0.2 mg/ml peptides were added. The plate was incubated for 7.5 min at 37 ºC. The medium was removed, the cells fixed, and the plate washed with Triton washing solution. The level of phosphorylates was assessed by incubation with phospho-EGFR (Tyr1045) antibody as a primary antibody, and Anti-rabbit IgG as a secondary antibody. The ability of different peptides to inhibit autophosphorylation of EGFR is presented by the decrease of the fluorescent signal (Y axis).

Accumulation of Fluorescent PEG-Peptide In Mice’s Cancer Tumors

EGFR antagonist peptide, attached to PEG, was labeled with Fluorescein, and injected intravenously to 5 Xenograft mice, bearing subcutaneous NCI-H1650 tumors (lung cancer that overexpress EGFR). The 6th mouse served as time 0, and was injected only with saline. Each mouse was subjected to anesthesia, perfusion and organ collection at a specific time point. The organs were homogenized in a volume of solution proportional to their weight, and spun down. Fluorescence of each sample was measured.

As can be seen, our peptide reached its targeted tumor cells, and accumulated there, unlike in the kidneys and the liver, where its concentration went down again.

Internalization of Fluorescent PEG-Peptide into Cancer Cells in Mice’s Tumors

The upper part of the photograph shows fluorescently labeled cancer cells taken from the tumors 1 hour and 24 hours after the injection. The lower part is a regular photograph of the same cells (no excitation that causes the fluorescence emission). In this part, cells that did not interact with the fluorescent peptide may be seen, but it looks like all, or most of the cells interacted with, and internalized the fluorescent peptide.

Efficacy Test - Killing Cancer Cells

We have synthesized a molecule that contains several copies of EGFR targeting peptide, which are bound to several copies of two different toxic peptides. We have tested the effect of this molecule on two kinds of cancer cell lines:

  • A431 – Human epithelial carcinoma that contains around 100,000 copies of EGFR on each cell.
  • MCF-7- Breast adenocarcinoma that contains around 3,000 copies of EGFR on each cell (a partial negative control).
  • Solutions were applied to the cells in a 96 well plate, and after 48 hours the wells were photographed.


As can be seen in the photographs, at concentrations above 3 micromolar, all A431 cells lost their tissue-like structure, and died. The partial negative control - survived.

Partial negative control

Mice experiment was performed by HBI Biotech Sciences (former Envigo . In this experiment we induced xenograft tumors of A549 (Human lung cancer) in 12 mice.

Only after the tumors were established (solid tumors) six mice were treated with MuTaTo.

That MuTaTo contained for the first time three different targeting peptides and one kind of a toxic peptide.

The other six mice served as a control group. They were treated with saline.

We gave 3 IV injections per week, for three weeks, and continue following the tumors for another week.

It is important to emphasize that the MuTaTo was injected to the tail vein of the mice not to the Tumor.

The results showed that the tumors development was inhibited in the test group, comparing to the control group.

Even after we stopped injections the tumors did not regain their accelerated rate of development.


TEL AVIV, ISRAEL – (December , 2018) – AEBI Ltd. (“AEBI” or the “Company”), a preclinical-stage biopharmaceutical company developing novel lead molecules for the treatment of certain types of cancer and many other diseases, today announced that the United States Patent and Trademark Office (USPTO) will issue a patent for the Company’s drug discovery platform technology. US Patent No. 10,160,967 entitled Methods and Compositions for Identifying a Peptide Having an Intermolecular Interaction With a Target of Interest is due to issue on December 25, 2018.

“This important patent in the United States augments the robust intellectual property position we are building globally. AEBI has been granted patents and has filed pending applications in major markets including the U.S and European Patent Office. We continue to strengthen our intellectual property portfolio through new patent filings on the most recent inventions, including peptide molecules identified by use of AEBI’s proprietary platform technology,” stated Dan Aridor, Chairman of the Board of AEBI. “The US is one of the largest markets in the world for development of peptide drug molecules, especially designed to provide solutions for diseases with few effective treatment options available. We look forward to developing peptide-based drug leads as a potential treatment to serve these unmet needs.”

About AEBI’s Drug discovery platform

AEBI’s Drug Discovery technology provides a method for identifying peptide molecules which have an interaction with a target of interest. Simply stated, AEBI’s technology can identify new molecules that should be able to increase a desired interaction or to diminish or prevent an undesired interaction. Sometimes the peptides themselves may serve as potential drugs or they may serve as a basis for improved drug designs.

This  invention provides a recombinant bacteriophage virus libraries,  wherein each virus contains a protein involved in viral attachment or infection, a polypeptide which differs by at least a single amino acid from another peptide or polypeptide in the library, and a modified cleavage site that is proximal to the peptide and the protein. The cleavage site is modified such that a compound mediating cleavage has a reduced binding affinity for it as compared to a non-modified cleavage site. The invention further involves a “target of interest complex” comprising a protease, a target of interest involved in an intermolecular interaction, and a flexible linker that attaches the protease and target of interest. This complex technology provides a method for identifying a peptide which has an interaction with a target of interest or identifying the agonistic or antagonistic feature of a peptide that has an intermolecular reaction with a target of interest.
