Objective: This post-marketing surveillance (PMS) was conducted to evaluate the incidence of adverse events with nivolumab in patients with unresectable, advanced or recurrent malignant pleural mesothelioma (MPM) that had progressed after first-line chemotherapy and to identify factors that potentially affected its safety in real-world clinical practice.

Methods: Patients who had not received nivolumab previously were registered between November 2018 and February 2021. Nivolumab was given intravenously 240 mg every 2 weeks or 480 mg every 4 weeks.

Article Synopsis
  • * Of the patients analyzed, significant adverse events occurred in 63.5%, with infusion reactions and liver dysfunction being the most common, highlighting the need for careful monitoring in patients with a history of stem cell transplants or thyroid issues.
  • * The overall response rate to nivolumab treatment was 61.7%, indicating its effectiveness was consistent with previous clinical trials, suggesting it is a viable option for patients with relapsed/refractory cHL.

Nivolumab, a monoclonal antibody against human programmed death 1, was approved for the treatment of melanoma in July 2014 in Japan. Because the Japanese phase II studies (ONO-4538-02, ONO-4538-08) enrolled small numbers of melanoma patients, post-marketing surveillance (PMS; JapicCTI-163 272) was conducted to collect safety data in a larger patient population. We report data for melanoma patients who received nivolumab between July 4, 2014 and February 28, 2017.

Background: This postmarketing surveillance study evaluated the real-world safety and effectiveness of nivolumab as salvage (after ≥ 2 lines) therapy in Japanese patients with unresectable advanced or recurrent gastric/gastroesophageal junction (G/GEJ) cancer.

Methods: This multicenter, observational study was conducted at 158 centers in Japan. Patients with unresectable advanced or recurrent G/GEJ cancer were registered between Nov 1, 2017, and Oct 31, 2018, and observed for 6 months after treatment initiation with nivolumab.

Postmarketing surveillance of Japanese patients with unresectable, previously treated, advanced or recurrent non-small-cell lung cancer treated with nivolumab was undertaken during the conditional approval period. The study aim was to evaluate the occurrence of treatment-related adverse events of nivolumab in the real world. Patients were registered between December 2015 and March 2016 at 536 sites.

Background: On the basis of phase III CheckMate 141 results, nivolumab was approved for recurrent or metastatic head and neck cancer after undergoing platinum-containing chemotherapy in Japan. This post-marketing surveillance aimed to evaluate the safety and effectiveness of nivolumab for head and neck cancer in the real-world setting.

Methods: All patients with head and neck cancer who planned to receive nivolumab were centrally registered.
