Camrelizumab (SHR-1210) alone or in combination with gemcitabine plus cisplatin for nasopharyngeal carcinoma: results from two single-arm, phase 1 trials
Abstract
Platinum-based doublet chemotherapy regimens, preferentially gemcitabine plus cisplatin, are generally considered the first-line standard of care for patients with recurrent or metastatic nasopharyngeal carcinoma. However, no consensus has been reached regarding treatment following progression after first-line therapy. Camrelizumab (SHR-1210) is a humanised anti-programmed death-1 (anti PD-1) antibody. We present safety and preliminary antitumour activity of camrelizumab alone as second-line therapy in patients with recurrent or metastatic nasopharyngeal carcinoma and combined with gemcitabine and cisplatin as first-line therapy in this patient population. We report the results from two single-arm, phase 1 trials. Both trials included patients aged 18-70 years with histologically or cytologically confirmed nasopharyngeal carcinoma and confirmed metastatic disease or locoreginal recurrence, and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients who received at least one previous line of treatment were enrolled at five academic hospitals in China into the dose-escalation and expansion trial to receive camrelizumab monotherapy intravenously at escalating doses of 1 mg/kg, 3 mg/kg, and 10 mg/kg, and a brid...Continue Reading

Cell Checkpoints & Regulators
Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.
Anemia
Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
