On 19 April 2019, the FDA approved the programmed death 1 (PD-1) inhibitor pembrolizumab (KEYTRUDA®, Merck) plus axitinib – a selective and potent receptor tyrosine kinase inhibitor of vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3 – as a first-line treatment for advanced renal cell carcinoma (RCC) patients.
Immunotherapy with programmed death 1 (PD-1) antibody pembrolizumab led to an objective response rate (ORR) of 14.6% in previously treated advanced cervical cancer patients with PD-L1–positive disease, as reported by Chung et al. on behalf of the KEYNOTE-158 investigators in the Journal of Clinical Oncology.
Combining programmed death 1 ligand (PD-L1) inhibitor atezolizumab with MEK-inhibitor cobimetinib in patients with previously treated metastatic colorectal cancer (mCRC) does not improve the overall survival (OS) when compared to regorafenib, as was reported by the investigators of the IMblaze370 (NCT02788279) trial in the Lancet Oncology.
On 4 April 2019, the US FDA approved palbociclib (Ibrance®, Pfizer) plus aromatase inhibitor or fulvestrant for the treatment of male patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer.
On 12 April 2019, the FDA granted accelerated approval to erdafitinib (Balversa®, Janssen) for the treatment of locally advanced or metastatic urothelial cell carcinoma (mUCC) progressed during or following a platinum-containing regimen, including progression within 12 months of (neo)adjuvant platinum-based chemotherapy, and whose tumours harbour susceptible fibroblast growth factor receptor (FGFR) 3 or FGFR2 genetic alterations as determined by the FDA approved companion diagnostic (CDx), the therascreen® FGFR RGQ RT-PCR Kit by Qiagen.
On 18 March 2019, the FDA approved atezolizumab (Tecentriq®, Genentech) plus carboplatin and etoposide as front-line treatment of adult extensive-stage small cell lung cancer (ES-SCLC) patients.
On 8 March 2019, the FDA granted accelerated approval to atezolizumab (Tecentriq®, Genentech/Roche) in combination with albumin-bound paclitaxel (nab-paclitaxel) for the treatment of adult unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) patients with programmed death 1 ligand (PD-L1) stained tumour-infiltrating immune cells (IC) of any intensity covering ≥1% of the tumour area, as determined by the VENTANA PD-L1 (SP142) Assay companion diagnostic (CDx).

On 22 February 2019, the FDA approved the fixed combination tablets of the nucleoside metabolic inhibitor trifluridine plus the thymidine phosphorylase inhibitor tipiracil (Lonsurf®, Taiho Pharmaceutical) for the treatment of adult metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma patients pretreated with two or more prior lines of chemotherapy including a fluoropyrimidine, a platinum, and either a taxane or irinotecan plus (when appropriate) HER2/neu-targeted therapy.
