Breakthrough Cancer Drug Offers Hope by Targeting Tumors Without Harming Healthy Cells

In a major advancement for cancer treatment, scientists at City of Hope Hospital in Los Angeles have developed a groundbreaking drug, AOH1996, that targets solid tumors while leaving healthy cells unharmed.

The drug, currently in Phase 1 clinical trials, specifically targets a protein called PCNA, which plays a key role in cancer cell growth and DNA repair.

Previously considered “undruggable,” this protein has now been successfully inhibited by the new treatment, offering hope to millions of cancer patients.

Dr. Linda Malkas, the molecular oncologist leading the research, highlighted the drug’s unique approach.

“Our cancer-killing pill is like a snowstorm that shuts down flights, but only for planes carrying cancer cells,” said Dr. Malkas, emphasizing its ability to halt tumor growth without causing harmful side effects.

The drug has already shown effectiveness against 70 different types of cancer in laboratory tests, including breast, prostate, and lung cancers.

The breakthrough drug, named in honor of a young girl who died of cancer in 2005, represents a turning point in cancer therapy.

Dr. Long Gu, co-author of the study, remarked on the challenges of targeting PCNA.

“PCNA was viewed as ‘undruggable,’ but City of Hope developed a medicine to overcome this,” he said.

The development has sparked renewed optimism for more personalized and less toxic cancer treatments in the future, offering a lifeline to patients with otherwise difficult-to-treat cancers.
