The oral medication works by targeting PARP, an enzyme in the body that helps to repair damaged cells — including cancer cells.

By inhibiting PARP, the drug stops the repair of cancerous cells to prevent them from growing. Penn investigators Janos Tanyi, MD, PhD, and Sunil Singhal, MD, led its Phase 2 and 3 clinical trials leading to approval.

And belzutifan marketed as Welirig , the first treatment of its kind to treat or intercept cancer in von Hippel-Lindau disease-associated tumors, such as those in renal cell carcinoma and central nervous system hemangioblastomas — a new cancer drug with Penn connections from basic science discovery about cancer hypoxia through to the definitive clinical trial leading to its approval.

On Jan. has dropped 33 percent. Every single drug you see advertised on TV — once upon a time, some patient somewhere was the first patient ever treated with it. This is why we do what we do. Many therapies that start in oncology eventually have broader disease applications — like CAR T cell therapy, which is already showing promise with other diagnoses, like the autoimmune disease lupus.

Since , the FDA has approved more than two dozen new therapies with roots at Penn Medicine — almost half of which are first-in-class for their indications. Becoming a hub for drug research and development took a lot more than luck.

Putting Biomedical Research Advances Within Reach: Treatments and vaccines are only useful in the hands of the people who need them. Penn Medicine is published three times a year for the alumni and friends of the University of Pennsylvania Health System and the Perelman School of Medicine at the University of Pennsylvania by the Department of Communications.

The lead author is Miles Linde, PhD, a former PhD student in immunology who is now at the Fred Hutchinson Cancer Institute in Seattle. T cells, part of the immune system that learns to identify and attack new pathogens such as viruses, can be trained to recognize specific cancer antigens, which are proteins that generate an immune response.

For instance, in CAR T-cell therapy, T cells are taken from a patient, programmed to recognize a specific cancer antigen, then returned to the patient. But there are many cancer antigens, and physicians sometimes need to guess which ones will be most potent.

A better approach would be to train T cells to recognize cancer via processes that more closely mimic the way things naturally occur in the body — like the way a vaccine teaches the immune system to recognize pathogens. Something similar in cancer would be for APCs to gather up the many antigens that characterize a cancer cell.

That way, instead of T cells being programmed to attack one or a few antigens, they are trained to recognize many cancer antigens and are more likely to wage a multipronged attack on the cancer.

Now that researchers have become adept at transforming one kind of cell into another, Majeti and his colleagues had a hunch that if they turned cancer cells into a type of APC called macrophages, they would be naturally adept at teaching T cells what to attack.

The study builds on prior research from the Majeti lab showing that cells taken from patients with a type of acute leukemia could be converted into non-leukemic macrophages with many of the properties of APCs.

In the current study, the researchers programmed mouse leukemia cells so that some of them could be induced to transform themselves into APCs.

When they tested their cancer vaccine strategy on the mouse immune system, the mice successfully cleared the cancer. Other experiments showed that the cells created from cancer cells were indeed acting as antigen-presenting cells that sensitized T cells to the cancer.

The team tested the same approach using mouse fibrosarcoma, breast cancer, and bone cancer. With all three cancers, the creation of tumor-derived APCs led to significantly improved survival. Lastly, the researchers returned to the original type of acute leukemia. When the human leukemia cell-derived APCs were exposed to human T cells from the same patient, they observed all the signs that would be expected if the APCs were indeed teaching the T cells how to attack the leukemia.
