Article Synopsis
- Checkpoint inhibitor therapy, particularly nivolumab combined with ipilimumab, shows promise for patients with high tumor mutational burden (TMB-H) across various tumor types, indicating a potential survival benefit.
- The study involved 201 patients with advanced solid tumors who were resistant to standard treatments; they were randomly assigned to receive either the combination of nivolumab and ipilimumab or nivolumab alone, with the effectiveness measured based on objective response rates.
- Results demonstrated higher response rates in patients with TMB-H tumors who received the combination therapy, and the safety profile was acceptable, suggesting this treatment could be beneficial for patients with limited options.
Background: Nearly all patients with newly diagnosed glioblastoma experience recurrence following standard-of-care radiotherapy (RT) + temozolomide (TMZ). The purpose of the phase III randomized CheckMate 548 study was to evaluate RT + TMZ combined with the immune checkpoint inhibitor nivolumab (NIVO) or placebo (PBO) in patients with newly diagnosed glioblastoma with methylated MGMT promoter (NCT02667587).
Methods: Patients (N = 716) were randomized 1:1 to NIVO [(240 mg every 2 weeks × 8, then 480 mg every 4 weeks) + RT (60 Gy over 6 weeks) + TMZ (75 mg/m2 once daily during RT, then 150-200 mg/m2 once daily on days 1-5 of every 28-day cycle × 6)] or PBO + RT + TMZ following the same regimen.
Phase II results from a phase I/II study to assess the safety and efficacy of weekly nab-paclitaxel in paediatric patients with recurrent or refractory solid tumours: A collaboration with the European Innovative Therapies for Children with Cancer Network.

Background: The phase I component of a phase I/II study defined the recommended phase II dose and established the tolerability of nab-paclitaxel monotherapy in paediatric patients with recurrent or refractory solid tumours. The activity and safety of nab-paclitaxel monotherapy was further investigated in this phase II study.
Patients And Methods: Paediatric patients with recurrent or refractory Ewing sarcoma, neuroblastoma or rhabdomyosarcoma received 240 mg/m of nab-paclitaxel on days 1, 8 and 15 of each 28-day cycle.
Introduction: Preclinical and early clinical studies suggest that combining epigenetic agents with checkpoint inhibitors can potentially improve outcomes in patients with previously treated advanced non-small cell lung cancer (NSCLC). This phase 2 trial examined second-line pembrolizumab + CC-486 (oral azacitidine) in patients with advanced NSCLC.
Methods: Patients with one prior line of platinum-containing therapy were randomised in a ratio of 1:1 to CC-486 or placebo, on days 1-14, in combination with pembrolizumab on day 1 of a 21-day cycle.
Background: nab-Paclitaxel has demonstrated efficacy in adults with solid tumours and preclinical activity in paediatric solid tumour models. Results from phase I of a phase I/II study in paediatric patients with recurrent/refractory solid tumours treated with nab-paclitaxel are reported.
Patients And Methods: Patients with recurrent/refractory extracranial solid tumours received nab-paclitaxel on days 1, 8 and 15 every 4 weeks at 120, 150, 180, 210, 240, or 270 mg/m (rolling-6 dose-escalation) to establish the maximum tolerated dose (MTD) and recommended phase II dose (RP2D).
