“The combination of the CD122-biased cytokine NKTR-214 and the PD-1 inhibitor nivolumab (Opdivo) demonstrated target lesion reductions of 72% for patients with advanced cancers, according to findings from the phase Ib PIVOT-02 trial presented at the 2017 SITC Annual Meeting.
“The dose escalation trial enrolled patients in the first- or second-line setting with advanced non–small cell lung cancer (NSCLC), renal cell carcinoma (RCC), and melanoma. The objective response rates (ORR) by RECIST criteria ranged from 46% to 75% across tumor types. Additionally, the combination was tolerable, with no discontinuations attributed to adverse events (AEs).”
“Neoadjuvant treatment with the combination of nivolumab (Opdivo) and ipilimumab (Yervoy) demonstrated almost a tripling in objective response rate (ORR) compared with the PD-1 inhibitor alone but at the cost of significant added grade 3 adverse events (AEs) for patients with high-risk resectable melanoma, according to a small study presented at the 2017 SITC Annual Meeting.
“In the combination arm (n = 11), the ORR was 73% and 50% of patients achieved a pathological complete response (pCR). With nivolumab alone (n = 12), the ORR was 25% and the pCR rate was 25%. Unfortunately, these gains in response were accompanied by 73% of patients in the combination arm having a grade 3 AE compared with just 8% in the single-agent arm. This high level of toxicity led the researchers to close the study early, according to Sangeetha M. Reddy, MD, MSci. Reddy worked on this trial with co-investigators Rodabe Amaria, MD, and Jennifer Wargo, MD.”
“The combination of an oncolytic virus plus a checkpoint inhibitor improved survival among patients with advanced melanoma compared with monotherapy, according to data from a phase 2 study published in Journal of Clinical Oncology.
“Novel monotherapies, such as ipilimumab (Yervoy, Bristol-Myers Squibb) — a CTLA-4 antibody — have ‘transformed patient care in advanced melanoma,’ the researchers wrote.”
“New data from Novartis’s breast cancer drug Kisqali underscored its effectiveness in pre-menopausal women, the Swiss drugmaker said, amid efforts to muscle in on turf dominated by rival Pfizer’s Ibrance.
“A late-stage trial showed Kisqali, in concert with hormonal therapies, halted the advance of hormone-receptor positive, human epidermal growth factor receptor-2 negative advanced breast cancer in pre-menopausal women for longer than in women getting hormonal therapy alone, Novartis said on Wednesday.”
“Patients with advanced neuroendocrine tumors (NETs) reported similar health-related quality of life (HRQOL) during treatment with a recently approved chemotherapy drug as compared to patients receiving a placebo treatment, according to a clinical trial published in Lancet Oncology.
“These findings, in conjunction with previous research showing delayed disease progression, suggest the drug, called everolimus, may be able to preserve quality of life even in light of chemotherapy’s often-toxic side effects. The findings support the usefulness of HRQOL as an endpoint in clinical trials studying NETs, in a secondary analysis of their findings, according to the study.”
“An ovarian cancer drug can leak through the blood brain barrier to reach brain tumours and could be an effective treatment for glioblastoma, suggest results* presented at the National Cancer Research Institute’s (NCRI) Cancer Conference in Liverpool, today (Monday).
“The Cancer Research UK-funded OPARATIC trial,* which was managed by the charity’s Centre for Drug Development, tested whether the ovarian cancer drug olaparib could reach glioblastoma, a type of brain tumour which is very difficult to treat. And early results show it successfully reaches brain tumours at high enough levels for treatment.”
“Osimertinib (Tagrisso) has impressed researchers in the field of EGFR-mutant non–small cell lung cancer (NSCLC), most recently with results from the phase III FLAURA trial solidifying its benefit.
“In FLAURA, treatment with frontline osimertinib led to a median progression-free survival (PFS) of 18.9 months (95% CI, 15.2-21.4). This represented a 54% risk reduction in progression or death compared with a standard EGFR tyrosine kinase inhibitor (TKI) for patients with locally advanced or metastatic EGFR-mutant NSCLC.”
“Inovio Pharmaceuticals, Inc. (NASDAQ:INO) today initiated a phase 1b/2a immuno-oncology trial in patients with newly diagnosed glioblastoma (GBM) designed to evaluate cemiplimab (also known as REGN2810), a PD-1 inhibitor developed by Regeneron Pharmaceuticals, Inc.(NASDAQ:REGN), in combination with Inovio’s INO-5401 T cell activating immunotherapy encoding multiple antigens and INO-9012, an immune activator encoding IL-12.”
“In women with estrogen receptor-positive, hormone-refractory metastatic breast cancer, oral Z-endoxifen hydrochloride, the potent metabolite of tamoxifen, provided substantial drug exposure regardless of CYP2D6 genotype, acceptable toxicity, and promising antitumor activity, researchers reported.
“Results from a phase I study in 38 patients with metastatic breast cancer demonstrated a clinical benefit rate (stable disease ≥ 6 months) of 26.3%. including a partial response by RECIST criteria in three patients who experienced progression during prior tamoxifen therapy, according to Matthew P. Goetz, MD, of the Mayo Clinic in Rochester, Minnesota, and colleagues.”
