On 20 May 2021, the US Food and Drug Administration (FDA) approved nivolumab (Opdivo, Bristol-Myers Squibb Company) for patients with completely resected oesophageal or gastro-oesophageal junction cancer with residual pathologic disease who have received neoadjuvant chemoradiotherapy.

Efficacy was evaluated in CHECKMATE-577 (NCT02743494), a randomised, multicentre, double-blind study in 794 patients with completely resected (negative margins) oesophageal or gastro-oesophageal junction cancers who had residual pathologic disease following concurrent chemoradiotherapy. Patients were randomised (2:1) to receive either nivolumab 240 mg or placebo every 2 weeks for 16 weeks followed by 480 mg of nivolumab or placebo every 4 weeks beginning at week 17 for up to one year of treatment.

The main efficacy outcome measure was disease-free survival (DFS), defined as the time between randomisation date and the first recurrence (local, regional, or distant from the primary resected site) date, or death, from any cause, as assessed by the investigator prior to subsequent anti-cancer therapy.

CHECKMATE-577 demonstrated a statistically significant improvement in DFS for patients receiving nivolumab as compared to those on the placebo arm. The median DFS was 22.4 months (95% confidence interval [CI] 16.6, 34.0) versus 11 months (95% CI 8.3, 14.3), respectively (hazard ratio 0.69; 95% CI: 0.56, 0.85; p = 0.0003). The DFS benefit was observed regardless of tumour PD-L1 expression and histology.

The most common adverse reactions (incidence ≥20%) in patients receiving nivolumab are fatigue, rash, musculoskeletal pain, pruritus, diarrhoea, nausea, asthenia, cough, dyspnoea, constipation, decreased appetite, back pain, arthralgia, upper respiratory tract infection, pyrexia, headache, abdominal pain, and vomiting.

The recommended nivolumab dose for adjuvant treatment of resected oesophageal or gastro-oesophageal junction cancer is 240 mg every 2 weeks or 480 mg every 4 weeks for a total treatment duration of 1 year. Both doses are administered as 30-minute intravenous infusions.

This review was conducted under Project Orbis, an initiative of the FDA Oncology Center of Excellence (OCE). Project Orbis provides a framework for concurrent submission and review of oncology drugs among international partners. For this review, FDA collaborated with the Australian Therapeutic Goods Administration, Health Canada, and Switzerland’s Swissmedic. The application reviews are ongoing at the other regulatory agencies.

This review used the Real-Time Oncology Review pilot programme, which streamlined data submission prior to the filing of the entire clinical application, and the Assessment Aid, a voluntary submission from the applicant to facilitate the FDA’s assessment.

Nivolumab received orphan drug designation for this indication.

Healthcare professionals should report all serious adverse events suspected to be associated with the use of any medicine and device to FDA’s MedWatch Report.
