“In December 2016, the FDA informed Advanced Accelerator Applications that its new drug application for Lutathera (177Lutetium DOTA-octreotate) as a treatment for patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) would need to be resubmitted.
“The application was based on the phase III NETTER-1 trial, which randomized patients with advanced, progressive, somatostatin receptor-positive midgut NETS to receive either Lutathera (116 patients) plus best supportive care, including octreotide long-acting repeatable (LAR), or octreotide LAR alone (113 patients).”
“A phase I trial found that the HER2 inhibitor ONT-380 had a lower incidence of certain adverse events associated with this class of agent and notable anti-tumor activity in heavily pretreated patients with HER2-positive metastatic breast cancer (MBC).
” ‘Though existing targeted therapies are improving outcomes in patients with HER2-positive MBC, disease resistance does eventually develop in most patients,’ wrote study authors led by Stacy Moulder, MD, of the MD Anderson Cancer Center in Houston. Also, some agents preclude combination with other regimens due to off-target effects such as skin rash and diarrhea.”
“The addition of hormonal therapy to radiation treatment following surgery significantly improved survival in patients with recurrent prostate cancer, according to the results of a study published in The New England Journal of Medicine.
“In the multicenter trial—which initially enrolled 760 men with biochemical recurrence after radical prostatectomy—patients were randomly assigned to treatment with bicalutamide or placebo for 2 years, along with 6.5 weeks of radiation therapy.”
“Results from a large clinical study showed that testing pediatric brain tumors for genetic abnormalities is feasible and could play a role in guiding patients’ treatment.
“The study, published in Neuro-Oncology, showed that more than half of the samples taken from pediatric brain tumors and analyzed using genomic profiling had genetic irregularities that could influence how the disease was diagnosed or treated with approved drugs or agents being evaluated in clinical trials.”
“A prospective study is investigating whether breast cancer surgery can be eliminated in patients who respond well to neoadjuvant systemic therapy.
“The phase II single-center trial, conducted out of The University of Texas MD Anderson Cancer Center (NCT02945579), aims to determine how often breast cancer recurs in patients who previously received chemotherapy and follow-up radiation therapy, but not surgery, and have no evidence of disease. Forty patients with early-stage, triple-negative or HER2-positive breast cancer care underwent image-guided biopsy after completing chemotherapy and before beginning radiation therapy to see if surgery is necessary.”
“Exercise does not appear to have any effect on the development of lymphedema in breast cancer patients, according to findings presented here at the Cancer Survivorship Symposium (CSS) Advancing Care and Research.
“Rates of lymphedema were almost the same for women randomly allocated to receive education only and for women allocated to receive education plus personalized exercise instruction from a physical therapist.
“At 18 months, there was no difference in the incidence of lymphedema. The lymphedema free rate was 58% in the education-only arm vs 55% in education-plus-exercise group.”
“One in four men presenting with elevated prostate-specific antigen (PSA) may be able to safely avoid prostate biopsy if they have triage testing with multi-parametric magnetic resonance imaging (MP-MRI) first, researchers said.
“The use of MP-MRI might also improve the detection of clinically significant cancer compared with transrectal ultrasound-guided prostate biopsy (TRUS-biopsy) and reduce over-diagnosis of clinically insignificant prostate cancer, the multicenter, paired-cohort, confirmatory PROMIS (PROstate MR Imaging Study) showed.”
“Philip W. Kantoff, MD, chair of the Department of Medicine, Memorial Sloan Kettering Cancer Center and a 2014 Giants of Cancer Care winner for Genitourinary Cancer, discusses the combination of docetaxel (Taxotere) chemotherapy and androgen deprivation therapy (ADT) in the setting of metastatic hormone-sensitive prostate cancer.
“Considering the positive results in overall survival from the CHAARTED and STAMPEDE trials, which combined ADT with docetaxel, the next step became determining which patients would benefit from this combination.”
“The antibody-drug conjugate sacituzumab govitecan (IMMU-132) produced high objective response rates, many of them quite durable, in a multicenter study of heavily pretreated patients with metastatic triple-negative breast cancer, presented at the 2016 San Antonio Breast Cancer Symposium.
“Trop-2 is a calcium signal transducer that drives tumor growth and has shown promise as a novel therapeutic target in triple-negative breast cancer, since the majority of these tumors express Trop-2. Sacituzumab govitecan targets Trop-2 and selectively delivers high doses of SN-38, the active metabolite of irinotecan that is 1,000 times more active than the parent compound. In addition to drug delivery, sacituzumab govitecan potentially also activates antibody-dependent cell-mediated cytotoxicity.”
