Scientists Develop ‘Groundbreaking’ Pills That Can Kill All Solid Cancer Tumors-Report

By Daniel Ojukwu

Scientists have developed a groundbreaking cancer drug that kills all solid cancer tumors while leaving other cells unharmed.

The new molecule, codenamed AOH1996 – targets a protein present in most cancers that helps tumors grow and multiply in the body. It is significant because this protein, the proliferating cell nuclear antigen (PCNA), was previously thought to be ‘undruggable’.

According to Mail Online, the drug was tested on 70 different cancer cells in the lab – including those derived from breast, prostate, brain, ovarian, cervical, skin, and lung cancer – and was effective against them all.

The drug is the culmination of 20 years of research and development by the City of Hope Hospital in Los Angeles, one of America’s largest cancer centers.

The good news comes months after scientists who invented the Pfizer Covid vaccine said that cancer will be curable within the coming decade.

The latest study, published in the journal Cell Chemical Biology, revealed that the new drug had been tested on more than 70 cancer cell lines and several normal human cells that did not have cancer but were used as a control.

The molecule selectively killed cancer cells by disrupting their normal reproductive cycle, preventing cells with damaged DNA from dividing, and stopping the replication of faulty DNA.

This combination of factors caused the cancer cells to die without harming healthy cells in the process.

The results will now need to be replicated in people. The drug is currently being tested on humans in a Phase 1 clinical trial at City of Hope.

Dr. Linda Malkas, Professor in City of Hope’s Department of Molecular Diagnostics and Experimental Therapeutics and the M.T. & B.A. Ahmadinia Professor in Molecular Oncology leads the team.

She explained how the molecule selectively disrupts DNA replication and repair in cancer cells, leaving healthy cells unaffected.

She said: “Most targeted therapies focus on a single pathway, which enables wily cancer to mutate and eventually become resistant.

“PCNA is like a major airline terminal hub containing multiple plane gates.

“Data suggests PCNA is uniquely altered in cancer cells, and this fact allowed us to design a drug that targeted only the form of PCNA in cancer cells.

“Our cancer-killing pill is like a snowstorm that closes a key airline hub, shutting down all flights in and out only in planes carrying cancer cells”.

Dr Malkas said results so far have been “promising’ as the molecule can suppress tumor growth on its own or in combination with other cancer treatments ‘without resulting in toxicity”.

The new therapy comes from 20 years of research and development and targets a cancerous variant of PCNA, a protein that in its mutated form is critical in DNA replication and repair of all expanding tumors, which helps cancers to repair and grow.

Study co-author associate research professor Dr Long Gu, said: ‘No one has ever targeted PCNA as a therapeutic because it was viewed as “undruggable,” but clearly City of Hope was able to develop an investigational medicine for a challenging protein target.
