Do You Know the Next Generation of Antibody–Drug Conjugates?

Nature magazine reports that on November 30th, researchers at the Symposium on Molecular Targets and Cancer Therapeutics in Munich, Germany will gather and discuss the next generation of antibody–drug conjugates (ADCs). These ADCs, or remodeled antibodies that bring anti-cancer drugs into tumor cells while minimizing damage to healthy tissue, are currently going through clinical trials. The first generation of ADCs mostly failed to work effectively and proved to have safety risks.

The antibody of the ADC will scout out and attach itself to a cancerous cell before being absorbed by the cell. The antibody-drug link will then be cut by the cell, allowing the drug to kill the dangerous cell. The aforementioned previous generation of ADCs encountered problems such as being too unstable or not releasing the drug in the cancer cell.

Nature reports that there are more than 40 ADCs now in clinical testing stages, and that “researchers are also mining a wealth of data from cancer-sequencing projects in search of new targets for antibodies to latch onto.” Various other researchers and companies are trying new methods, such as ditching the antibody and using a smaller strand of amino acids to permeate deeper into cancer cells.

Highlighted MSK Research Fall 2016

Age should not be a deterrent when treating lung cancer patients. According to a recent study in JCO by thoracic surgeon, Dr. Prasad Adusumilli, older patients with stage 1 non-small cell lung cancer did quite well post-surgery, and after five years 9 out of 10 patients were alive and cancer free. Morton Pollner, one of Dr. Adusumilli’s patients was 76 when he was diagnosed with lung cancer. That was 7 years ago, and today Mr. Pollner is 82, cancer free, and enjoying life. “Whatever I get from here on, it’s like gravy,” he says.

MSK’s Chief of Genitourinary Oncology Service, Dr. Howard Scher, was interviewed by OncLive, where he discussed some of the challenges and developments in prostate cancer treatments. One of the most promising developments in prostate cancer treatment is using liquid biopsies. Since drawing blood is much less risky and costly, the benefits are significant. Liquid biopsies look for multiple tumor products, including circulating tumor cells, and DNA and RNA from tumors. The patient’s blood provides a window into their tumors, and what therapies those tumors will respond to, even when their tumors have metastasized into a variety of regions Continue reading

Abuzz this Week, Clinical Trials, Mesh and Critical Questioning

Stat News Gut Check questions whether Clinical Trials overstate the effectiveness of cancer drugs for most patients. A recent piece in JAMA Oncology and a 2016 study looking at differences in trial patients versus regular patients may indicate that they do.

Hey Medical Librarians, it’s time to roll up our sleeves and get acquainted with the new MeSH Browser!

From the ACRLog (Association of College and Research Libraries) comes a timely discussion on of the importance – and difficultly – of asking critical questions. On Critical Habits of Mind, by Veronica Arellano Douglas concludes, “Critical questioning is not just an information literacy or academic skill, it’s a life practice and habit of mind we’ll need in the years to come.” With the confusion and uncertainty following the election and the debate about fake news gaming social media algorithms, it is crucial for everyone, not just librarians or researchers, to practice and teach critical thinking skills.
