“The now-published results from the EMBRACA study confirm that talazoparib (Pfizer), a poly-adenosine diphosphate-ribose polymerase (PARP) inhibitor, prolongs progression-free survival (PFS) in patients with advanced BCRA-positive breast cancer compared with single-agent chemotherapy alone, and that it also significantly improves quality of life.
” ‘This is the largest randomized trial in BRCA mutation carriers [ever undertaken] and demonstrates PARP efficacy,’ Jennifer Litton, MD, associate professor in the Department of Breast Medical Oncology, University of Texas MD Anderson Cancer Center, Houston, told Medscape Medical News in an email.”
“In a phase II trial funded by the European Organisation for Research and Treatment of Cancer and reported in The Lancet Oncology, van den Bent et al found no evidence of a survival benefit with the addition of bevacizumab (Avastin) to temozolomide in patients with a first recurrence of World Health Organization grade II or III glioma without the 1p/19q codeletion.
“In the open-label trial, conducted at 32 European centers, 155 patients were randomized between February 2011 and July 2015 to receive either temozolomide at 150 to 200 mg/m² on days 1 to 5 every 4 weeks for a maximum of 12 cycles (n = 77) or the same temozolomide regimen plus bevacizumab at 10 mg/kg every 2 weeks until disease progression (n = 78). Previous chemotherapy must have been stopped at least 6 months before enrollment, and radiotherapy, at least 3 months before enrollment. Overall, 44% of patients in the combination group and 47% in the temozolomide group had grade III disease.”
“ASCO and Friends of Cancer Research (Friends) have submitted recommended language to the U.S. Food and Drug Administration (FDA) for five guidance documents on ways to broaden eligibility criteria for cancer clinical trials. The recommendations are part of an ASCO and Friends collaboration to broaden eligibility for participating in clinical trials by addressing five specific areas: minimum age requirements for trial enrollment, HIV/AIDS status, brain metastases, organ dysfunction, and prior and concurrent malignancies.”
“In a planned subgroup analysis of the phase III AURA3 trial reported in the Journal of Clinical Oncology, Wu et al found that the third-generation EGFR tyrosine kinase inhibitor osimertinib (Tagrisso) produced higher central nervous system (CNS) response rates vs platinum plus pemetrexed (Alimta) in patients with advanced EGFR T790M-positive non–small cell lung cancer (NSCLC).
“In AURA3, 419 patients with disease progression on prior EGFR tyrosine kinase inhibitor treatment were randomized 2:1 to receive osimertinib at 80 mg once daily or platinum plus pemetrexed. The current subgroup analysis was conducted in patients with measurable or nonmeasurable CNS lesions on baseline brain scan by blinded independent central neuroradiologic review.”
“Adding abiraterone acetate (Zytiga) to enzalutamide (Xtandi) did not improve progression-free survival (PFS) after prostate-specific antigen (PSA) progression in men on enzalutamide monotherapy for chemotherapy-naive metastatic castration-resistant prostate cancer (mCRPC), researchers found.
“In the randomized, double-blind PLATO trial, the median PFS in patients treated with enzalutamide plus abiraterone and prednisone was 5.7 months. By comparison, the PFS was 5.6 months in the control group treated with abiraterone and prednisone plus placebo (hazard ratio [HR] 0.83; P=0.22).”
“First-line atezolizumab plus nab-paclitaxel improved PFS compared with placebo among patients with metastatic or unresectable locally advanced triple-negative breast cancer, according to interim results from the IMpassion130 trial released by the manufacturer.
“Researchers observed prolonged PFS in both the intention-to-treat population and the PD-L1-positive population.”
“The first patient has been dosed in a phase I/II open-label, multicenter trial investigating a novel immunotherapy combination in patients with newly diagnosed glioblastoma (GBM). Fifty patients have been accrued in the trial, as of May 31, 2018, which will be conducted at 25 sites across the nation.
“This study aims to investigate the efficacy of INO-5401, a T-cell activating immunotherapy agent encoding multiple antigens in GBM, and INO-9012, an immune activator encoding IL-12, in combination with the PD-1 inhibitor cemiplimab (REGN2810).”
“Men with newly diagnosed, nonmetastatic prostate cancer had a 5-year failure-free survival (FFS) of 88% when treated with focal high-intensity focused ultrasound (HIFU) therapy, results of a multicenter European clinical experience showed.
“The 625-patient cohort had a 5-year overall survival of 99%, and none of the patients died of prostate cancer during a median follow-up of 56 months. In a subgroup of men who submitted questionnaires on patient-reported outcomes, 98% said they did not require absorbent pads for urinary incontinence.”
“Some of the 165,000 U.S. men who are estimated to receive a new diagnosis of prostate cancer this year will develop resistance to hormonal therapies for the disease, but a new study by a doctor now at Northwestern Memorial Hospital points to use of an existing drug to help treat them.
“This kind of aggressive cancer has challenged doctors, as effective treatment to improve outcomes for these men hadn’t existed previously. But a clinical trial led by Dr. Maha Hussain, now an oncologist at Northwestern Memorial, showed that taking a drug, enzalutamide, resulted in a 71 percent lower risk of cancer spread or death, compared to those taking a placebo during the three-year trial. The patients involved all had prostate cancer that hadn’t spread but that also had not responded to hormone treatment.”
