Purpose: Limited data exist on the optimal duration of immunotherapy, including for non-small-cell lung cancer (NSCLC). We present an exploratory analysis of CheckMate 153, a largely community-based phase IIIb/IV study, to evaluate the impact of 1-year fixed-duration versus continuous therapy on the efficacy and safety of nivolumab.

Methods: Patients with previously treated advanced NSCLC received nivolumab monotherapy (3 mg/kg every 2 weeks). Those still receiving treatment at 1 year, including patients perceived to be deriving benefit despite radiographic progression, were randomly assigned to continue nivolumab until disease progression or unacceptable toxicity or to stop nivolumab with the option of on-study retreatment after disease progression (1-year fixed duration).

Results: Of 1,428 patients treated, 252 were randomly assigned to continuous (n = 127) or 1-year fixed-duration (n = 125) treatment (intent-to-treat [ITT] population). Of these, 89 and 85 patients in the continuous and 1-year fixed-duration arms, respectively, had not progressed (progression-free survival [PFS] population). With minimum post-random assignment follow-up of 13.5 months, median PFS was longer with continuous versus 1-year fixed-duration treatment (PFS population: 24.7 months 9.4 months; hazard ratio [HR], 0.56 [95% CI, 0.37 to 0.84]). Median overall survival from random assignment was longer with continuous versus 1-year fixed-duration treatment in the PFS (not reached 32.5 months; HR, 0.61 [95% CI, 0.37 to 0.99]) and ITT (not reached 28.8 months; HR, 0.62 [95% CI, 0.42 to 0.92]) populations. Few new-onset treatment-related adverse events occurred. No new safety signals were identified.

Conclusion: To our knowledge, these findings from an exploratory analysis represent the first randomized data on continuous versus fixed-duration immunotherapy in previously treated advanced NSCLC and suggest that continuing nivolumab beyond 1 year improves outcomes.

Safety, Efficacy, and Patient-Reported Health-Related Quality of Life and Symptom Burden with Nivolumab in Patients with Advanced Non-Small Cell Lung Cancer, Including Patients Aged 70 Years or Older or with Poor Performance Status (CheckMate 153).

Introduction: CheckMate 153 (NCT02066636) is a phase 3B/4 study assessing nivolumab in previously treated patients with advanced NSCLC. Eligibility criteria allowed enrollment of patients with poor prognostic features of advanced age or diminished Eastern Cooperative Oncology Group performance status (ECOG PS), which are typically underrepresented in or excluded from randomized controlled trials.

Methods: Patients with stage IIIB or IV NSCLC and an ECOG PS of 0 to 2 with disease progression after at least one systemic therapy received nivolumab (3 mg/kg every 2 weeks) until progression, unacceptable toxicity, or consent withdrawal. The primary end point was the incidence of grade 3 to 5 select treatment-related adverse events (TRAEs).

Results: Among 1426 treated patients, 556 (39%) were aged 70 years or older and 128 (9%) had an ECOG PS of 2. The median treatment duration was 3.2 months. Across subgroups and the overall population, the incidences of select grade 3 to 5 TRAEs (6%-9%) and grade 3 or 4 TRAEs (12%-14%) were similar. One grade 5 TRAE was documented. The median overall survival time was comparable in the overall population (9.1 months) and patients aged 70 years or older (10.3 months) but shorter in patients with an ECOG PS of 2 (4.0 months). Patient-reported outcomes generally improved.

Conclusions: Data from this large predominantly community-based study, which included patients aged 70 years or older and with an ECOG PS of 2, are consistent with registrational studies. As expected, the median overall survival for patients with an ECOG PS of 2 was lower than for the overall population but comparable with historical data.

Safety profile of nivolumab administered as 30-min infusion: analysis of data from CheckMate 153.

Cancer Chemother Pharmacol 2018 04 13;81(4):679-686. Epub 2018 Feb 13.

Bristol-Myers Squibb, Princeton, NJ, USA.

Purpose: Nivolumab has been administered using a 60-min infusion time. Reducing this time to 30 min would benefit both patients and infusion facilities. This analysis compared the safety of 30- and 60-min infusions of nivolumab in patients with previously treated advanced non-small cell lung cancer.

Methods: CheckMate 153 is an open-label, phase 3b/4, predominantly community-based study ongoing in the United States and Canada. Patients with stage IIIB/IV disease with progression/recurrence after at least one prior systemic therapy received nivolumab 3 mg/kg every 2 weeks over 30 or 60 min for 1 year or until disease progression. The primary outcome overall was to estimate the incidence of grade 3-5 treatment-related select adverse events; a retrospective objective was to estimate the incidence of hypersensitivity/infusion-related reactions (IRRs) with the 30-min infusion. Exploratory pharmacokinetic analyses were performed using a population pharmacokinetics model.

Results: Of 1420 patients enrolled, 369 received only 30-min infusions and 368 received only 60-min infusions. Similar frequencies of hypersensitivity/IRRs were noted in patients receiving 30-min [2% (n = 8)] and 60-min [2% (n = 7)] infusions. Grade 3-4 treatment-related hypersensitivity/IRRs led to treatment discontinuation in < 1% of patients in each group; < 1% of patients in each group received systemic corticosteroids. Hypersensitivity/IRRs were managed by dosing interruptions, with minimal impact on total dose received. Nivolumab pharmacokinetics were predicted to be similar in the two groups.

Conclusions: Nivolumab infused over 30 min had a comparable safety profile to the 60-min infusion, including a low incidence of IRRs.
