Israel Cancer Cure Claims Are Literally Incredible—Show Us the Data

We are constantly bombarded with media announcements of miraculous breakthroughs in cancer treatment, giving the false impression that the disease is well on the way to being eliminated as a serious threat. But non-experts—including most reporters—often fail to understand that the improvements in prevention, detection, and treatment are not like the Salk polio vaccine virtually wiping out a dread disease almost overnight. Rather, with cancer—a term that encompasses many different diseases—what we see are modest, incremental, statistical improvements in outcomes.  

That is just one reason to be wary of the claim by a team of Israeli scientists under the leadership of Dr. Ilan Morad, CEO of Accelerated Evolution Biotechnologies, that they will likely perfect a revolutionary cure for all cancer in the next year.

There are a number of other reasons to be skeptical.

The company released a few details about the putative cure called MuTaTo, for multi-target toxin. It uses cancer-targeting peptides, which are chains of amino acids (the building blocks of proteins) linked to a toxin that kills cancer cells.

By using several targeting peptides linked to a potent toxin, Morad said they “made sure that the treatment will not be affected by mutations; cancer cells can mutate in such a way that targeted receptors are dropped by the cancer.” In other words, their approach would supposedly prevent cancer cells from losing their susceptibility to the toxin.

That simplistic description is unsatisfying. Cancer is complicated on many levels–biology, prevention, diagnosis and treatment. For one thing, it is many different diseases, with distinct structures and metabolism, and we have learned in recent years that even what appears to be the same type of tumor under a microscope—lung, breast, brain, and so on—can have many different causes and prognoses.  

For example, although most lung cancers and tumors of the throat are caused by cigarette smoking, some lung cancers are related to a genetic mutation that is not at all related to smoking, and some throat cancers are strongly related to a viral infection—human papillomavirus. Blood-borne cancers, such as leukemia, are different still.

There are plenty of other reasons, scientific and otherwise, to doubt Morad’s claims.

First, responsible scientists don’t make announcements of revolutionary scientific or medical breakthroughs, in the absence of convincing data in peer-reviewed publications, or at the very least, presented in detail at professional conferences.

Second, the findings on which the claims are based are from mouse studies. But researchers on cancer and other diseases have learned—often, the hard way—that rodent studies don’t translate well to humans.

Third, clinical trials of at least some types of cancer would require years to conduct.  Even if data were in hand for, say, a certain subset of breast cancers, there is no guarantee that the results would be translatable to any other cancers, let alone all.

Finally, the scope and definitiveness of the claims for the new treatment strain credulity.  “We believe we will offer in a year’s time a complete cure for cancer,” said Dan Aridor, chairman of the board of Accelerated Evolution Biotechnologies. “Our cancer cure will be effective from day one, will last a duration of a few weeks and will have no or minimal side-effects at a much lower cost than most other treatments on the market.”  

Such claims about both safety and efficacy are, literally, incredible, in the absence of human clinical trials and peer-reviewed, published data.

The scientific community has reacted with justifiable suspicion, and even outright derision, to the bombastic announcement.  A typical response was that of Dr. Benjamin Neel, director of Perlmutter Cancer Center at NYU Langone Health, (as quoted in the NY Post), that “cancer is multiple diseases, and it is highly unlikely that this company has found a ‘cure’ for cancer any more than there is a single cure for infections.”  He continued, “more likely, this claim is yet another in a long line of spurious, irresponsible and ultimately cruel false promises for cancer patients.”
