BUFFALO, N.Y. (PRWEB)

Dozens of cancer specialists at Roswell Park Comprehensive Cancer Center have been invited to present their latest advances in cancer research at the annual meeting of the American Association for Cancer Research (AACR), which will take place in New Orleans, Louisiana, from April 8 to 13.

Among the many Roswell Park researchers presenting their findings in areas ranging from newly approved targeted therapies to innate cancer immunity, highlights include a plenary session, a minisymposium and three late-breaking abstracts reporting findings from ongoing clinical trials.

Plenary: Clinical Trials Targeting the DNA Damage Response and KRAS

Grace Dy, MD, Chief of Thoracic Oncology in the Department of Medicine, will give a podium presentation reporting long-term outcomes in a study investigating the effectiveness of sotorasib, a drug that targets mutations of the KRAS gene, in patients with non-small cell lung cancer (NSCLC). Dr. Dy will discuss new information from the pivotal CodeBreaK100, a phase 1/2 trial that led to accelerated U.S. Food and Drug Administration approval last year of sotorasib for treatment of KRAS G12C-mutated NSCLC. Dr. Dy will highlight these findings Sunday, April 10, both in an afternoon oral presentation and in an AACR press conference at 11 a.m. CT onsite at the meeting.

Minisymposium: Age and the Tumor Microenvironment

Irwin Gelman, PhD, Distinguished Professor of Oncology in the Department of Cancer Genetics and Genomics, will present the results of his research into the role of a protein, HBP1, and drugs that target this protein, in controlling breast cancer dormancy reawakening.

“A significant portion of breast cancer cases recur years, sometimes decades after all evidence of the initial disease has been removed by surgery, systemic drug therapy and/or radiation, because cells that metastasize early in the initial breast cancer disseminate to and colonize peripheral sites, including the bone,” says Dr. Gelman. “We are planning a preclinical study to assess how effective two repurposed drugs may be in decreasing breast cancer recurrence and increasing the long-term survival of breast cancer patients.”

In a minisymposium Tuesday, April 12, Dr. Gelman will share results of a Roswell Park study that used genomic screens to identify genes that specifically control breast cancer dormancy in the bone. The team discovered that shutting off the HBP1 gene, which normally turns off pathways that promote the growth and aggressiveness of metastases, causes the reawakening of dormant breast cancer cells grown in bone microenvironment culture conditions. Dr. Gelman will highlight how interactions between breast cancer and bone cells facilitate this dormancy signaling, and how drugs such as cyproheptadine may prevent the breast cancer metastases in the bone.

Late-Breaking Abstracts

Three Roswell Park researchers have been invited to share highly anticipated data on Monday, April 11, from ongoing phase 1 and 2 clinical trials for the treatment colorectal cancer, melanoma and breast cancer, in late-breaking poster abstracts.

Sarbajit Mukherjee, MD and Shipra Gandhi, MD, both Assistant Professors of Oncology in the Department of Medicine, will report findings from two studies that are part of a novel immunotherapy platform in development at Roswell Park under the leadership of Pawel Kalinski, MD, PhD, involving modulation of key proteins known as chemokines.

Dr. Mukherjee will present initial results of a phase 2 study evaluating a chemokine-modulatory regimen in patients with colorectal cancer metastatic to the liver (abstract CT105/ LB-7312), and Dr. Gandhi will present Systemic rintatolimod and interferon-α2b selectively reprogram local tumor microenvironment in patients with metastatic triple negative breast cancer for enhanced influx of cytotoxic T-lymphocytes but not regulatory T-cells (abstract CT145/ LB-7620).

Benjamin Switzer, DO, a Fellow in the Department of Hematology, will report findings from a phase 2 clinical trial that advances knowledge in another signature area of Roswell Park research — the role of the sympathetic nervous system in cancer and response to cancer treatment. His presentation is β-2 adrenergic receptor (AR): Another immune checkpoint (IC)” A phase II clinical trial of propranolol (P) with pembrolizumab (Pem) in patients with unresectable stage III and stage IV melanoma (abstract CT568/ LB-7806).
