“Treating older patients who have malignant brain cancer with the chemotherapy drug temozolomide plus a short course of radiation therapy extends survival by two months compared to treating with radiation alone, show clinical trial results published in the New England Journal of Medicine.
“For 45% of the study participants, improved survival almost doubled — from 7 months to 13.5 months, says co-principal investigator Normand Laperriere, radiation oncologist at Princess Margaret Cancer Centre, University Health Network. This was linked to a molecular marker that indicated if a DNA repair mechanism against the drug was active. When the mechanism was ‘off,’ tumours responded better to treatment.”
“Eli Lilly and Co’s combination of its experimental breast cancer drug and another widely used treatment slowed disease progression in patients who relapsed or did not benefit enough when treated with the anti-estrogen therapy.
“In August, an independent data monitoring committee recommended the late-stage study continue without modification, even though interim evaluation suggested the combination treatment was not delaying cancer progression.
“Lilly’s drug, abemaciclib, is part of the same new class of breast cancer treatments as Pfizer Inc’s Ibrance, and Novartis AG’s newly approved Kisqali.”
“Adding temozolomide chemotherapy to short-course radiotherapy for older patients with glioblastoma was tied to longer progression-free and overall survival than with a short course of radiotherapy alone, researchers found.
“In a randomized controlled trial of glioblastoma patients ages 65 and up, those on combination therapy had a significantly lower risk of death during the study than those who had only radiation (HR 0.67, 95% CI 0.56-0.80, P<0.001), James Perry, MD, of Sunnybrook Research Institute in Toronto, and colleagues reported in the New England Journal of Medicine.”
“Despite breast tumors’ lower mutational loads than lung cancers and melanoma—cancers in which immunotherapy have shown particular promise—breast cancers are nevertheless immunogenic, Elizabeth A. Mittendorf, MD, PhD, of the University of Texas MD Anderson Cancer Center in Houston, reported at the 34th Annual Miami Breast Cancer Conference, held March 9–12 in Miami Beach, Florida.
“Multiple clinical trials are now underway to evaluate immunotherapy strategies in breast cancer, Mittendorf noted.
“Combination immunotherapy regimens are ‘likely the way forward’ and appropriate combinatorial strategies will hinge importantly on disease stage, she said.”
“Bristol-Myers Squibb Co on Thursday said it has decided not to seek accelerated U.S. approval for a combination of its two immunotherapy drugs as an initial treatment for lung cancer.
“Shares of Bristol, which closed at $55.49 on the New York Stock Exchange, were down 6.2 percent at $52.08 after hours.
“The pharmaceutical company cited ‘a review of data available at this time’ for the decision to hold off on filing for Food and Drug Administration approval of the combination of its cancer drugs Opdivo and Yervoy.”
“Incyte Corporation (Nasdaq:INCY) and Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced the decision to advance the clinical development program investigating the combination of epacadostat, Incyte’s investigational oral selective IDO1 inhibitor, with KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy.
“With the expansion of the clinical development program, the companies plan to initiate pivotal studies of epacadostat in combination with KEYTRUDA in four additional tumors: non-small cell lung cancer, renal cell carcinoma, bladder cancer and squamous cell carcinoma of the head and neck. Presentations of data from the ongoing studies of epacadostat in combination with KEYTRUDA, which support this decision, are expected at upcoming medical meetings.”
“A leading-edge immunotherapy clinical trial at UConn Health’s Carole and Ray Neag Comprehensive Cancer Center has packed a one-two punch, successfully controlling a patient’s advanced lung cancer using the combined power of two immunotherapy drugs.
“For 50 years Michel Gueret, 67, of Canton was a heavy smoker. That is until May 2012, when he received the devastating news that he had advanced lung cancer while hospitalized for a collapsed lung at UConn John Dempsey Hospital.”
“Celgene Corporation (CELG) today announced that the results of its randomized phase II tnAcity trial of ABRAXANE® for injectable suspension (paclitaxel protein-bound particles for injectable suspension) (albumin-bound) will be presented at the 2016 San Antonio Breast Cancer Symposium (SABCS) December 6-10, 2016. The trial found that an investigational weekly combination regimen of ABRAXANE + carboplatin had significantly longer progression-free survival (PFS) (7.4 months) compared to weekly regimens of either ABRAXANE + gemcitabine (5.4 months) or of carboplatin + gemcitabine (6.0 months) as first-line treatment of patients with metastatic triple-negative breast cancer (mTNBC).”
“Palbociclib can help slow the progression of advanced breast cancer, according to a study published in the Nov. 17 issue of the New England Journal of Medicine.
“Richard Finn, M.D., an assistant professor of medicine at the University of California, Los Angeles, and colleagues tested palbociclib-letrozole as a first-line treatment for estrogen-receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer. They randomly assigned 666 women to receive the drug combination or letrozole alone, and followed them for up to three years.
“At that point, the researchers found that 43.7 percent of women in the palbociclib group had either died or seen their cancer progress. That compared with 61.7 percent of women on letrozole alone. Women on the drug combination typically remained progression-free for 24.8 months, versus 14.5 months for women on letrozole. One of the most common side effects—seen in two-thirds of women in this study—was neutropenia.”
