Pascal,” discusses results of a phase Ib/II dose-escalation study evaluating triple combination therapy with encorafenib, binimetiinib, and ribociclib (Kisquali) in patients with <em>BRAF V600</em> solid tumors and melanoma.
More than half of patients with immunotherapy-relapsed/refractory melanoma benefited from treatment with nivolumab and an anti-lymphocyte activation gene-3 (LAG-3) antibody, according to data from an early clinical study.
The experimental AKT inhibitor ipatasertib in combination with paclitaxel improved progression-free survival (PFS) as a first-line therapy for patients with locally advanced or metastatic triple-negative breast cancer when compared with paclitaxel alone, according to initial findings of the LOTUS trial presented during the 2017 ASCO Annual Meeting.<br />

Dabrafenib (Tafinlar) plus trametinib (Mekinist) achieved an intracranial response (IR) rate of 58% in melanoma that has metastasized to the brain.

In updated findings from the KEYNOTE-059 trial of pembrolizumab in advanced gastric or gastroesophageal junction (GEJ) cancer, the PD-1 inhibitor maintained signs of its clinical benefit in this patient population, which is encouraging as the indication is currently under consideration for approval with the FDA.
Nivolumab (Opdivo) plus ipilimumab (Yervoy) or ipilimumab alone are associated with a high incidence of gastrointestinal (GI) toxicity, but most adverse events (AEs) are effectively managed using immunomodulators, which do not appear to inhibit tumor response.
