Randomized Controlled TrialRandomized phase III trial of regorafenib in metastatic colorectal cancer: analysis of the CORRECT Japanese and non-Japanese subpopulations.
In the international, phase III, randomized, double-blind CORRECT trial, regorafenib significantly prolonged overall survival (OS) versus placebo in patients with metastatic colorectal cancer (mCRC) that had progressed on all standard therapies. This post hoc analysis evaluated the efficacy and safety of regorafenib in Japanese and non-Japanese subpopulations in the CORRECT trial. ⋯ Regorafenib appears to have comparable efficacy in Japanese and non-Japanese subpopulations, with a manageable adverse-event profile, suggesting that this agent could potentially become a standard of care in patients with mCRC.

Multicenter StudyPhase 1 study of ixazomib, an investigational proteasome inhibitor, in advanced non-hematologic malignancies.
Ixazomib is an investigational proteasome inhibitor with demonstrated antitumor activity in xenograft models of multiple myeloma (MM), lymphoma, and solid tumors. This open-label, phase 1 study investigated intravenous (IV) ixazomib, in adult patients with advanced non-hematologic malignancies. ⋯ In patients with solid tumors, ixazomib was associated with a manageable safety profile, limited antitumor activity, and evidence of downstream proteasome inhibition effects.

Xilonix, a novel true human antibody targeting the inflammatory cytokine interleukin-1 alpha, in non-small cell lung cancer.
Advanced non-small cell lung cancer (NSCLC) patients were treated as part of a Phase I dose escalation and expansion study evaluating a true human monoclonal antibody targeting IL-1α (Xilonix), which is intended to modulate the malignant phenotype-inhibiting tumor growth, spread and offering relief of symptoms. ⋯ Xilonix was well tolerated, with gains in LBM and improvement in symptoms suggesting a clinically important response. Although not statistically significant, the survival outcomes observed for patients with and without prior anti-EGFR therapy raises intriguing questions about the potential synergy of IL-1α blockade and anti-EGFR therapy. Further study for this agent in NSCLC is warranted.

Phase I and pharmacokinetics/pharmacodynamics study of the MEK inhibitor RO4987655 in Japanese patients with advanced solid tumors.
RO4987655 is an oral and selective inhibitor of MEK, a key enzyme of the mitogen-activated protein kinase (MAPK) signaling pathway. This phase I dose-escalation study of RO4987655 in Japanese patients with advanced solid tumors aimed to determine maximum tolerated dose (MTD) and to evaluate safety, pharmacokinetics (PK), pharmacodynamics (PD), and anti-tumor activity. Patients received a single dose of RO4987655 (1, 2, 4, 5, or 6.5 mg) followed by continuous once-daily dosing (1, 2, or 4 mg QD) or twice-daily dosing (4, 5, or 6.5 mg BID) in 28-day cycles. ⋯ One esophageal cancer patient had confirmed partial response and seven patients showed progression-free survival for longer than 16 weeks. The MTD of RO4987655 for Japanese patients was determined as 8 mg/day (4 mg BID). RO4987655 was tolerated up to the MTD with a favorable PK/PD profile in Japanese patients with advanced solid tumors.

Multicenter StudyPhase-I dose finding and pharmacokinetic study of the novel hydrophilic camptothecin ST-1968 (namitecan) in patients with solid tumors.
This is a first-in-human, phase I, dose-escalation study to determine the maximum tolerated dose (MTD) of intravenous, flat-dosed ST-1968 (namitecan), a new hydrophilic camptothecan derivative. ⋯ This study demonstrates clinical safety, favourable pharmacokinetics and preliminary antitumor activity of the novel hydrophilic camptothecin analogue namitecan in patients with heavily pretreated solid malignancies, when given either on a 2 out of 3 weeks or 3-weekly regimen.
