Purpose: Patients with / wild-type melanoma who progress after immune checkpoint inhibitors (ICIs) have a poor prognosis. MEK inhibition has shown activity in this patient population but is associated with treatment-limiting skin toxicity. Combining a BRAF inhibitor with a MEK inhibitor is associated with less skin toxicity.

Article Synopsis
  • Radiotherapy combined with immune checkpoint blockade (ICB) is being tested in a clinical trial involving oligometastatic cancer patients to see if it can enhance T-cell responses and improve outcomes.
  • In this phase II trial, patients were split into two groups: one receiving a combination of treatments immediately after radiotherapy (arm A) and a control group receiving pembrolizumab alone (arm B).
  • Results showed a higher one-year progression-free survival rate in arm A (10%) compared to arm B (0%), but overall, the study did not meet its main goal of improving long-term survival outcomes.

Melanoma patients failing all approved treatment options have a poor prognosis. The antimelanoma activity of regorafenib (REGO), a multitargeted kinase inhibitor, has not been investigated in this patient population. The objective response rate and safety of REGO treatment in advanced melanoma patients was investigated retrospectively.

Background: Patients with advanced melanoma who progress after treatment with immune checkpoint-inhibitors (ICI) and BRAF-/MEK-inhibitors (if mutated) have no remaining effective treatment options. The presence of CD1c (BDCA-1) and CD141 (BDCA-3) myeloid dendritic cells (myDC) in the tumor microenvironment correlates with pre-existing immune recognition and responsiveness to immune checkpoint blockade. The synthetic saponin-based immune adjuvant AS01 enhances adaptive immunity through the involvement of myDC.

Focal radiation necrosis of the brain (fRNB) is a late adverse event that can occur following the treatment of benign or malignant brain lesions with stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS). Recent studies have shown that the incidence of fRNB is higher in cancer patients who received immune checkpoint inhibitors. The use of bevacizumab (BEV), a monoclonal antibody that targets the vascular endothelial growth factor (VEGF), is an effective treatment for fRNB when given at a dose of 5-7.
