Current Research

Goal: To identify new therapeutic targets for the treatment of breast cancer, particularly BRCA-driven triple negative breast cancers (TNBCs).

Impact: Dr. Bertino is testing a new antibody-drug conjugate that, in laboratory studies, resulted in the shrinkage of TNBC tumors that are caused by mutations in the BRCA gene. If proven effective in clinical trials, the drug could one day be used alone or with other therapies to treat patients with this aggressive form of breast cancer.

What’s next: The team will test a second generation of the drug that is attached to a novel toxin that may be even more effective. They plan to test it alone and in combination with other therapies currently approved for treatment of BRCA-driven-TNBC, including drugs that block DNA repair and immunotherapy drugs.

There are limited targeted therapies for TNBC, and those that have been approved are not equally effective for all patients. Chemotherapy remains the standard of care for most of these patients, so new therapies are urgently needed. Dr. Bertino has developed a promising novel treatment for TNBC resulting from mutations in the BRCA gene. His studies have shown that the drug reduces tumors in laboratory models of the disease. He is now testing a conjugated version of the drug that may be even more effective.

Full Research Summary

Research area: Developing more effective therapies for triple negative breast cancer (TNBC) caused by mutations in the BRCA genes.

Impact: TNBC is difficult to treat because it lacks the three most common targets for breast cancer treatment (estrogen, progesterone, and HER2). Because TNBC has a poor prognosis, more effective treatments are urgently needed. Dr. Bertino is pursuing new therapeutic targets in order to develop effective treatment options with minimal toxicity for patients with TNBC.

Current investigation: He and his team have been working on a novel treatment that uses an antibody that binds to an enzyme (matriptase) found on TNBC cells. Because it doesn’t significantly bind to normal cells, this therapy should have few or no side effects for patients.

What he’s learned so far: In laboratory studies, the matriptase-targeting therapy shrunk TNBC tumors and had no side effects.

What’s next: Dr. Bertino and his colleagues will test a second generation antibody conjugated to a novel toxin that causes tumor DNA damage, which could potentially be even more effective in treating TNBC than the original drug. They will test it alone and in combination with an inhibitor of DNA repair and in combination with a checkpoint (PD-L1) inhibitor.

Biography

Dr. Joseph R. Bertino attended Cornell University and Downstate Medical School, SUNY. After internship and residency, he was a Fellow in Hematology and Biochemistry at The University of Washington. In 1961, he joined the faculty at Yale in Pharmacology/Medicine where he held several positions, including the first Director of Yale Cancer Center in 1973. He relinquished this position when he was awarded an ACS research professorship in 1975. He left Yale in 1987 for Memorial Sloan Kettering Cancer Center, where he was Head of the Molecular Pharmacology and Clinical Investigation Program. In 2002, he joined the Rutgers Cancer Institute of New Jersey as their Chief Scientific Officer and a University Professor of Medicine & Pharmacology at the Rutgers Robert Wood Johnson Medical School.

Dr. Bertino has received many honors for his work. He is a past president of AACR and ASCO, and was founding editor of the JCO. He continues to develop novel and treatments for cancer. He recently discovered a peptide that can regress E2F-1 oncogene addicted tumors, and is developing novel antibody-toxin conjugates to treat breast cancer.
