Lenvatinib plus Pembrolizumab for Advanced Endometrial Cancer.

Background: Standard therapy for advanced endometrial cancer after failure of platinum-based chemotherapy remains unclear.

Methods: In this phase 3 trial, we randomly assigned, in a 1:1 ratio, patients with advanced endometrial cancer who had previously received at least one platinum-based chemotherapy regimen to receive either lenvatinib (20 mg, administered orally once daily) plus pembrolizumab (200 mg, administered intravenously every 3 weeks) or chemotherapy of the treating physician's choice (doxorubicin at 60 mg per square meter of body-surface area, administered intravenously every 3 weeks, or paclitaxel at 80 mg per square meter, administered intravenously weekly [with a cycle of 3 weeks on and 1 week off]). The two primary end points were progression-free survival as assessed on blinded independent central review according to the Response Evaluation Criteria in Solid Tumors, version 1.

A single dose of neoadjuvant PD-1 blockade predicts clinical outcomes in resectable melanoma.

Immunologic responses to anti-PD-1 therapy in melanoma patients occur rapidly with pharmacodynamic T cell responses detectable in blood by 3 weeks. It is unclear, however, whether these early blood-based observations translate to the tumor microenvironment. We conducted a study of neoadjuvant/adjuvant anti-PD-1 therapy in stage III/IV melanoma.

T-cell invigoration to tumour burden ratio associated with anti-PD-1 response.

Despite the success of monotherapies based on blockade of programmed cell death 1 (PD-1) in human melanoma, most patients do not experience durable clinical benefit. Pre-existing T-cell infiltration and/or the presence of PD-L1 in tumours may be used as indicators of clinical response; however, blood-based profiling to understand the mechanisms of PD-1 blockade has not been widely explored. Here we use immune profiling of peripheral blood from patients with stage IV melanoma before and after treatment with the PD-1-targeting antibody pembrolizumab and identify pharmacodynamic changes in circulating exhausted-phenotype CD8 T cells (T cells).

The promise of chimeric antigen receptor T cells (CARTs) in leukaemia.

The success of genetically engineered T cells that express chimeric antigen receptors (CARTs) has been a momentous step forward in harnessing the potent cancer fighting abilities of the immune system. The efficacy seen in relapsed/refractory (r/r) acute lymphoblastic leukaemia (ALL), not only by inducing remission, but also in maintaining long-term disease control, has been unprecedented. While the foundation for this approach has been firmly set in place, continued development will improve the efficacy, toxicity and applicability to other malignancies of this new class of 'living drugs'.

Approach to patients with primary refractory acute myeloid leukemia.

Purpose Of Review: Despite successful remission induction in 60-80% of patients with newly diagnosed acute myeloid leukemia, there remain a significant number of patients who exhibit primary refractory disease. Here we examine the data for predicting likelihood of having refractory disease, available therapeutic options, and how to decide the appropriate treatment option for a patient.

Recent Findings: Recently identified recurrent molecular mutations and early response to chemotherapy as determined by kinetics of peripheral blast clearance or nadir bone marrow biopsy assist in determining the likelihood of primary refractory disease.

Altered editing in cyclic nucleotide phosphodiesterase 8A1 gene transcripts of systemic lupus erythematosus T lymphocytes.

The aetiopathogenesis of the abnormal immune response in systemic lupus erythematosus (SLE) remains incompletely understood. We and other investigators demonstrated altered expression of adenosine deaminase that act on RNA (ADAR) genes in SLE patients. Based on this information, we hypothesize that the altered expression and function of ADAR enzymes is a mechanism for the immunopathogenesis of SLE.
