AACR Annual Meeting

A phase II basket trial has been announced to test that mutations in isocitrate dehydrogenase 1 and 2 are not driver mutations that should be targeted with direct IDH inhibitors, but instead they create vulnerabilities that can be exploited through treatment with PARP inhibitors.

Treatment with the RAF dimer inhibitor BGB-283 led to clinical benefit for patients with BRAF V600-mutated melanoma, papillary thyroid cancer, and ovarian cancer.

Results of a phase II trial showed that more than 80% of patients with refractory non-Hodgkin lymphoma achieved objective responses to treatment with the chimeric antigen receptor (CAR) T-cell therapy axicabtagene ciloleucel.

Julie R. Brahmer, MD, associate professor of Oncology, Bloomberg Kimmel Institute for Cancer Immunotherapy at Johns Hopkins, discusses 5-year follow-up data from the CA209-003 study of nivolumab in previously treated advanced non-small cell lung cancer (NSCLC).

Jason J. Luke, MD, assistant professor of Medicine, The University of Chicago Medicine, discusses the controversy surrounding the combination of nivolumab (Opdivo) and ipilimumab (Yervoy) in treatment-naïve patients with advanced melanoma, which was explored in the CheckMate-067 trial, during the AACR Annual Meeting.

Long-term survival in patients with metastatic non–small cell lung cancer who received the immune checkpoint inhibitor nivolumab (Opdivo) has proven to be much higher than expected, with 16% of these patients surviving after 5 years, equivalent to about 4 times what would be expected with chemotherapy.

The PD-1 and CTLA-4 inhibitor combination of nivolumab (Opdivo) and ipilimumab (Yervoy) was associated with a 12% reduction in the risk of death versus nivolumab monotherapy in patients with treatment-naïve advanced melanoma.

Treatment with the PD-L1 inhibitor avelumab induced an objective response rate of 33% in patients with advanced Merkel cell carcinoma in the phase II JAVELIN Merkel 200 study, including 2 additional complete responses since the primary analysis.

According to results presented at the 2017 AACR Annual Meeting, 10% of patients showed impressive long-term survival in a phase I study of single agent anti-PD-L1 atezolizumab (Tecentriq) in patients with metastatic triple-negative breast cancer.

A dual attack on HER2 expression resulted in a 30% objective response rate in heavily pretreated patients with HER2-positive metastatic colorectal cancer.

The irreversible pan-HER tyrosine kinase inhibitor neratinib showed single-agent activity across cohorts of patients with HER2-mutant advanced cancers.

Roger Stupp, MD, professor, Neurological Surgery, and associate director, Strategic Initiatives, Robert H.

Roberto Pili, MD, professor of Medicine and Robert Wallace Miller Professor of Oncology at Indiana University School of Medicine and a researcher at the Indiana University Melvin and Bren Simon Cancer Center, discusses the significance of the preliminary results of a phase I/II study, which examined the combination of the HDAC inhibitor entinostat and high-dose interleukin-2 (IL-2) in patients with previously untreated metastatic renal cell carcinoma (RCC) of clear cell histology.

Stuart Lutzker, MD, PhD, vice president of BioOncology Exploratory Clinical Development, Genentech, discusses results of the first-in-human study of OX40 agonist in patients with refractory solid tumors.

Julia R. Mendoza-Perez, PhD, visiting scientist, Epidemiology, The University of Texas MD Anderson Cancer Center, discusses next steps and research regarding obesity-related genes in patients with renal cell carcinoma (RCC).

Manish A. Shah, MD, associate professor of Medicine, Joan and Sanford I. Weill Department of Medicine, Bartlett Family Associate Professor in Gastrointestinal Oncology, medical oncologist, Weill Cornell Medicine and New-York Presbyterian Hospital, discusses the phase IIIb HELOISE trial, which compared 2 dose regimens of trastuzumab combined with chemotherapy as a first-line treatment for patients with HER2-positive metastatic gastric/gastroesophageal junction adenocarcinoma (mGC/GEJC).

Martine J. Piccart, MD, PhD, professor of Oncology, Université Libre de Bruxelles, director of Medicine, Jules Bordet Institute, Brussels, Belgium, discusses the primary analysis of the prospective randomized MINDACT study, which evaluated the clinical utility of the 70-gene signature (MammaPrint) combined with common clinical-pathological criteria for selection of patients for adjuvant chemotherapy in breast cancer with 0 to 3 positive nodes.
