Targeting PD-1 or PD-L1 in Metastatic Kidney Cancer: Combination Therapy in the First-Line Setting.
Recent FDA approvals of regimens targeting programmed death 1 (PD-1) in combination with anti-CTLA-4 or with VEGF tyrosine kinase inhibitors are reshaping front-line therapy for metastatic kidney cancer. In parallel, therapeutics specific for programmed death ligand 1 (PD-L1), one of the two major ligands for PD-1, are under continued investigation. ⋯ Here, we review current clinical data on combination immune checkpoint inhibitor therapy in metastatic kidney cancer and discuss the relevant biology of PD-1 and PD-L1. The design of future rational combination therapy trials in metastatic renal cell carcinoma will rely upon an understanding of this biology, along with an evolving understanding of immune cell populations and their functional states in the tumor microenvironment.

Randomized Controlled Trial Multicenter Study
A Phase II, Prospective, Randomized, Multicenter, Open-Label Study of GX-188E, an HPV DNA Vaccine, in Patients with Cervical Intraepithelial Neoplasia 3.
To determine the efficacy of the therapeutic DNA vaccine GX-188E for inducing regression of cervical intraepithelial neoplasia (CIN) 3. ⋯ GX-188E is an effective therapeutic vaccine against a cohort containing only CIN3 patients.

Immunogenicity derived from the murine scFv, a major molecular compomemt of chimeric antigen receptors (CARs), may limit the persistence of CAR T cells, resulting in tumor relapse of patients in complete remission (CR). In this study, we developed a humanized anti-CD19 scFv CAR-T (hCAR-T) to treat patients with relapsed/refractory acute lymphoblastic leukemia (r/r ALL). ⋯ T cells expressing the humanized anti-CD19 scFv CARs exhibited sustained therapeutic efficacy in the treatment of r/r ALL. Low replase rate was associated with the long-term persistence of CAR T cells.

Multicenter Study
First-in-Man Phase I Trial of the Selective MET Inhibitor Tepotinib in Patients with Advanced Solid Tumors.
Tepotinib is an oral, potent, highly selective MET inhibitor. This first-in-man phase I trial investigated the MTD of tepotinib to determine the recommended phase II dose (RP2D). ⋯ Tepotinib was well tolerated with clinical activity in MET-dysregulated tumors. The RP2D of tepotinib was established as 500 mg once daily. MET abnormalities can drive tumorigenesis. This first-in-man trial demonstrated that the potent, highly selective MET inhibitor tepotinib can reduce or stabilize tumor burden and is well tolerated at doses up to 1,400 mg once daily. An RP2D of 500 mg once daily, as determined from translational modeling and simulation integrating human population pharmacokinetic and pharmacodynamic data in tumor biopsies, is being used in ongoing clinical trials.

We aimed to investigate genomic correlates underlying extremes of survivorship in metastatic colorectal cancer and their applicability in informing survival in distinct subsets of patients with metastatic colorectal cancer. ⋯ Genomic analysis of extremes of survivorship following colorectal cancer metastasectomy identifies a prognostic role for coaltered Ras/B-raf-TP53 and its association with distinct patterns of colorectal cancer metastasis.
