Microsatellite instability (MSI) is an important predictive biomarker of response to immune checkpoint blockade in solid cancers. However, despite recommendations by clinical practice guidelines, MSI is often not assessed, usually due to tissue insufficiency, unavailability, or infeasibility....
An interim analysis of a small phase Ib study by O’Hara et al evaluating the CD40 agonistic monoclonal antibody APX005M in combination with gemcitabine and nab-paclitaxel with or without the programmed cell death protein 1 (PD-1) inhibitor nivolumab in untreated patients with metastatic...
The results of an analysis of pooled data from the phase Ib KEYNOTE-028 trial and the phase II KEYNOTE-158 study of the anti–programmed cell death protein 1 monoclonal antibody pembrolizumab in the treatment of advanced small cell lung cancer has found that the therapy provided antitumor...
A small phase I study by Navai et al investigated a combination of lymphodepletion chemotherapy and HER2-specific chimeric antigen receptor (CAR) T-cell therapy for pediatric and adult patients with advanced HER2-positive sarcoma. The combination showed promising antitumor activity and was found to ...
Although the emergence of immune checkpoint inhibitors over the last decade has revolutionized the treatment of patients with metastatic cancers, only a minority of patients experience long-lasting benefit from the therapy. A study investigating the association between tumor mutational burden and...
A study investigating the clinicopathologic features of BRAF V600E– and V600K–mutant melanomas and whether genotype affects response to immunotherapy found that the mutations not only have different clinical phenotypes, but also different molecular features and different...
Angiosarcoma of the head, face, neck, or scalp is a rare cancer associated with high rates of local recurrence, distant metastasis, and poor prognosis. Because angiosarcoma is so rare, it is difficult to conduct large-scale research in the cancer. To address this issue, the Broad Institute of MIT...
A preclinical study showing that a vaccination with a recombinant adenovirus expressing a truncated ErbB-2 antigen can cure advanced established murine breast cancer as well as extensive established metastatic lung cancer led to the launch of a small phase I study investigating a therapeutic cancer ...
Widespread use of antiretroviral therapy in the treatment of patients infected with human immunodeficiency virus (HIV) has led to a decline in the incidence of HIV-related Kaposi sarcoma, an incurable malignancy associated with HIV. Nevertheless, about 15% of these patients will go on to...
An analysis of newly diagnosed patients with cutaneous melanoma brain metastases treated with checkpoint blockade immunotherapy has found the treatment was associated with an increase in median overall survival of 12.4 months compared with 5.2 months—a 1.4-fold improvement. The benefit was...
Recent research has shown that the tumor microenvironment in older patients promoted melanoma metastasis and resistance to targeted therapy with a BRAF inhibitor. Now, a new study investigating the relationships among age, response to anti–programmed cell death protein 1 (PD-1)...
Persephone, a large phase III randomized noninferiority study conducted in the United Kingdom comparing 6 months to 12 months of trastuzumab (Herceptin) in patients with HER2-positive early breast cancer has found 6 months of trastuzumab to be noninferior to 12 months of the therapy. In addition,...
