Neuroendocrine tumors of the digestive system (GI-NETs) can arise in different parts of the digestive tract. GI-NETs originating in the ileum, duodenum, and appendix are known as midgut NETs, and tumors of the stomach, colon, and rectum are non-midgut NETs. Many of these tumors are functional; that is, they produce a variety of hormonal substances that cause serious, debilitating symptoms. Continue reading…
“Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) announced that it received a recommendation by an independent data monitoring committee (IDMC) that the J-ALEX Study, a phase III study targeting ALK fusion gene positive non-small cell lung cancer (NSCLC) being conducted in Japan, should be stopped early as the study met its primary endpoint at a pre-planned interim analysis. The study showed that patients lived significantly longer without disease worsening (progression-free survival, PFS) when treated with Alecensa® compared to crizotinib.
“The J-ALEX study is an open-label, randomized phase III study that compares the efficacy and safety between Alecensa and crizotinib. The J-ALEX study enrolled 207 patients with ALK fusion gene positive advanced or recurrent NSCLC who either had not undergone chemotherapy or had undergone one chemotherapy regimen. The subjects were allocated to the Alecensa group or the crizotinib group in a one to one ratio.”
“Several recent studies have shown promise for the treatment of pancreatic NETs (pNETs). In the phase II CALGB-80701, which investigated the addition of bevacizumab (Avastin) to a treatment paradigm of everolimus and octreotide (Sandostatin) LAR in patients with locally advanced or metastatic pNETs, bevacizumab extended progression-free survival (PFS) by more than 3 months compared with everolimus and octreotide LAR alone.
“Response rate was also higher in the bevacizumab arm, with a 31% response to everolimus plus bevacizumab versus a 12% response in the control arm. Toxicity, however, was significantly higher in the bevacizumab arm.”
“Array BioPharma (Nasdaq: ARRY) today reported top-line results from the ongoing Phase 3 clinical trial of binimetinib in patients with advanced NRAS-mutant melanoma, known as the NEMO trial. The study met its primary endpoint of improving progression-free survival (PFS) compared with dacarbazine treatment. The median PFS on the binimetinib arm was 2.8 months versus 1.5 months on the dacarbazine arm; hazard ratio (HR) 0.62, [95% CI 0.47-0.80], p < 0.001.”
“Among women with locally advanced or metastatic hormone receptor-positive breast cancer that was resistant to hormone therapy, those who had mutated PIK3CA detected in their blood benefited from a combination of the investigational PI3K inhibitor buparlisib and fulvestrant, according to data from the phase III BELLE-2 trial presented at the 2015 San Antonio Breast Cancer Symposium, held Dec. 8–12.
“ ‘BELLE-2 is a randomized, phase III clinical trial designed to assess the efficacy of the investigational PI3K inhibitor buparlisib in combination with fulvestrant in breast cancer patients whose tumors no longer respond to aromatase inhibitors,’ said José Baselga, MD, PhD, physician-in-chief and chief medical officer at Memorial Sloan Kettering Cancer Center in New York.”
“The approval was based on a substantial improvement in overall survival (OS) in a phase 3 study.
“The FDA has expanded the approval for single-agent Opdivo (nivolumab) to include the frontline treatment of patients with BRAF wild-type advanced melanoma, based on a substantial improvement in overall survival (OS) compared with the chemotherapy dacarbazine in a phase 3 study.
“In the data assessed by the FDA from the CheckMate-066 trial, the median OS with Opdivo was not reached versus 10.8 months for dacarbazine, representing a 58 percent reduction in the risk of death. Median progression-free survival (PFS) with Opdivo was 5.1 versus 2.2 months for dacarbazine.”
“The FDA has accepted a supplemental biologics license application for the Opdivo plus Yervoy regimen to include data from a phase 3 trial of patients with previously untreated advanced melanoma, according to a press release from Bristol-Myers Squibb.
“The agency also granted priority review of the application, with a target action date of Jan. 23, according to the release
” ‘Findings from CheckMate -067 provide additional evidence that the combination of the two immuno-oncology agents, Opdivo [nivolumab] and Yervoy [ipilimumab], may provide improved outcomes for patients with advanced melanoma, and has the potential to become the basis of how this devastating disease is treated,’ Michael Giordano, senior vice president, head of development for oncology at Bristol-Myers Squibb, said in a press release. ‘We saw significant clinical benefit from the Opdivo+Yervoy regimen in these patients, including an increase in the time patients lived without disease progression, and we look forward to working with the FDA to review this data.’ “
