“Mixed results have been reported with the use of shiitake mushrooms or extract in cancer, with reduced side effects associated with chemotherapy in those with advanced gastrointestinal cancer and no benefit in treating those with prostate cancer.”
“Matthew D. Hellmann, MD, medical oncologist, Memorial Sloan Kettering Cancer Center, discusses the CheckMate-032 study, which explored nivolumab (Opdivo) with or without ipilimumab (Yervoy) for patients with small cell lung cancer (SCLC).”
“Investigators are seeking to determine whether the addition of ABT-414, an antibody–drug conjugate, to concomitant radiotherapy and temozolomide will improve the survival of patients with newly diagnosed glioblastoma multiforme (GBM) with epidermal growth factor receptor (EGFR) amplification.
“The phase IIb/III Intellance1 trial (NCT02573324), which is currently recruiting participants, seeks to randomize approximately 720 patients to a 2-phase experimental arm with ABT-414 or to a placebo comparator arm. Participants in the experimental arm will receive intravenous ABT-414 combined with standard therapy of oral temozolomide and radiation in a chemoradiation treatment phase, followed by ABT-414 plus oral temozolomide during an adjuvant treatment phase. The comparator arm will follow the same regimens, with an intravenous placebo to replace ABT-414.”
“The addition of T-VEC (T-VEC; Imlygic), a herpes simplex virus 1-based oncolytic virus, to CTLA-4 inhibitor ipilimumab (Yervoy) improves the objective response rate (ORR) in patients with unresected stage IIIb to IV melanoma, according to findings presented at the 7th European Post-Chicago Melanoma/Skin Cancer Meeting.
“T-VEC was the first approved oncolytic virus therapy in Europe, the United States, and Australia, and its efficacy was previously demonstrated in a phase III trial comprising patients with advanced unresectable melanoma.”
“Abemaciclib penetrated brain metastases and had antitumor activity in patients with hormone receptor (HR)-positive, HER2-negative metastatic breast cancer, preliminary evidence suggests.
“Results were presented in a poster at the 2017 ASCO Annual Meeting for 23 patients from a stage 1 efficacy analysis from a phase II study.
” ‘What we found were 2 patients who experienced partial responses within the CNS, suggesting there is activity of the agent in the brain and in patients who have HR-positive disease,’ explained lead author Sara M. Tolaney, MD, MPH.”
“The boom of blood-based biomarkers has led to a turning point in clinical practice for physicians treating patients with non–small cell lung cancer (NSCLC). While tissue biopsies remain the standard approach, plasma assays—if positive—can direct patients to a first-line targeted treatment quicker.
” ‘Blood-based testing does have a role in patients with NSCLC,’ said Leora Horn, MD, MSc. ‘The blood can be potentially used as a surrogate for markers for directing for therapy. But if blood testing is negative, it is not enough to say that a patient is not positive. Those patients do need to go on to get a biopsy.’ ”
“Ceritinib appeared safe and effective in patients with ROS1–rearranged non–small cell lung cancer, according to a multicenter, open-label phase 2 study.
“ALK inhibitors — especially crizotinib (Xalkori, Pfizer) — effectively treat ROS1–positive cell lines and tumors. However, patients eventually develop resistance and experience a high incidence of brain recurrence.
” ‘Treatment options beyond crizotinib are needed, and clinical development of other ROS1 inhibitors should be accelerated to improve treatment outcome of patients with ROS1–positive NSCLC,’ Byoung Chul Cho, MD, PhD, assistant professor at Yonsei Cancer Center of Yonsei University College of Medicine, and colleagues wrote.”
“Men with advanced prostate cancer who respond poorly to one taxane-based chemotherapy regimen may benefit from switching to another, a small randomized trial reported.
“Nearly half of the men who did not achieve a ≥30% decline in prostate-specific antigen (PSA) level while receiving either docetaxel or cabazitaxel achieved a ≥50% decline when they switched to the other drug, said Emmanuel Antonarakis, MBBCh, of Johns Hopkins University in Baltimore, and colleagues.”
“Bristol-Myers got a much-needed boost with the earlier-than-expected news that Opdivo beat out Yervoy in a Phase III study focused on a particular niche for adjuvant melanoma therapy. And an analyst who’s been following the data says it could be worth a billion dollars in added annual sales.
“The big biotech says an interim analysis of Checkmate-238 provided researchers with proof that the PD-1 drug outperformed Yervoy, Bristol-Myers’ CTLA-4 drug, among advanced Stage IIIb or IV patients, cutting the recurrence rate for those who have undergone surgery. There are no bottom line numbers in the statement, but Bristol-Myers says they’ll be able to release data at an upcoming conference to show that Opdivo provided a significantly lower risk of disease recurrence.”
