Acute myeloid leukemia (AML) is a rare but deadly hematologic cancer. In 2018, approximately 19,500 new cases of AML were diagnosed, and more than 10,600 people died from the disease in the United States. Although up to 70% of adults with AML have a complete response to initial treatment with cytotoxic chemotherapy, the responses are not durable. The 5-year survival rate for people with AML is only 24%.

Prostate cancer is the third most common type of cancer in the United States, after breast cancer and lung cancer. In 2018 alone, 164,690 individuals were diagnosed with prostate cancer, accounting for nearly 10% of all new cancer cases, and 29,430 deaths were attributed to the disease. Prostate cancer is most frequently diagnosed in men aged 65 to 74 years (median age, 66 years). More than 98% of patients with prostate cancer survive ≥5 years; however, the 5-year survival rate drops to 30% for patients with metastatic disease.

Atlanta, GA—The combination of the investigational MET inhibitor savolitinib plus the EGFR inhibitor osimertinib (Tagrisso) achieved encouraging responses in patients with MET-amplified, EGFR-positive non–small-cell lung cancer (NSCLC) and acquired, MET-driven resistance to previous therapies, with an acceptable side-effect profile. These findings represent interim results of 2 expansion cohorts of a phase 1b clinical trial presented at the 2019 American Association for Cancer Research meeting.

The adjuvant use of the antibody-drug conjugate trastuzu­mab emtansine (T-DM1; Kadcyla) led to a clinically meaningful and significant improvement in disease-free survival versus trastuzumab (Herceptin) in patients with HER2-positive early breast cancer and residual invasive disease, despite the use of neoadjuvant chemotherapy plus HER2-targeted therapy.

San Francisco, CA—Moving combination immunotherapy into the neoadjuvant setting for patients with stage III melanoma induces a higher rate of pathologic response than adjuvant therapy, said Christian U. Blank, MD, PhD, Division of Molecular Oncology & Immunology, Netherlands Cancer Institute, ­Amsterdam, at the 2019 ASCO-­SITC Clinical Immuno-Oncology Symposium.

San Francisco, CA—Ovarian cancers with BRCA mutations are less immunogenic than other DNA repair–deficient tumors. Targeting the DNA damage response using PARP inhibitors may help to improve the modest responses of ovarian cancer seen with single-agent immune checkpoint inhibitors, said ­Panagiotis A. Konstantinopoulos, MD, PhD, Director of Translational Research, Division of Gynecologic Oncology, Dana-Farber Cancer Institute, Boston, at the 2019 ASCO-SITC Clinical Immuno-Oncology Symposium.

San Francisco, CA—Patients with ovarian cancer can respond to immunotherapy, but rationally designed synergistic combinations will be necessary to enhance upfront efficacy and to sustain durability, said Daniel J. Powell Jr, PhD, Scientific Director of Immunotherapy, Division of Gynecologic Oncology, Center for Cellular Immunotherapy, University of Pennsylvania, Philadelphia, at the 2019 ASCO-SITC Clinical Immuno-Oncology Symposium.

Atlanta, GA—Chimeric antigen receptor (CAR) T-cell therapy has had dramatic results in hematologic malignancies, but so far, getting CAR T-cells to work in solid tumors has proved elusive. That may be about to change if promising results from a phase 1 clinical trial are confirmed by further studies. The results of this pivotal study were presented at the 2019 American Association for Cancer Research (AACR) annual meeting.

Atlanta, GA—Preclinical and clinical data support the potential for the investigational novel tyrosine kinase inhibitor (TKI) infigratinib for the treatment of different FGFR-driven tumor types, according to Sameek Roychowdhury, MD, PhD, Associate Professor, Medical Oncology, the Ohio State University, Columbus, who presented a poster with the preclinical results at the 2019 American Association for Cancer Research (AACR) meeting.

Atlanta, GA—The investigational PI3K inhibitor umbralisib had encouraging activity as monotherapy in patients with relapsed or refractory marginal-zone lymphoma in an analysis of the phase 2 UNITY-NHL trial. Interim results were presented at the 2019 American Association for Cancer Research (AACR) meeting.
