MA09.05 - Nivolumab Alone or with Ipilimumab in Recurrent Small Cell Lung Cancer (SCLC): 2-Year Survival and Updated Analyses from the Checkmate 032 Trial (ID 4397)
14:50 - 14:56 | Author(s): M.D. Hellmann
- Abstract
- Presentation
Background:
Patients with SCLC and disease progression during/after first-line platinum-based chemotherapy have poor prognoses and limited treatment options. Nivolumab alone and in combination with ipilimumab has shown survival benefit and durable responses in multiple tumor types. Here we present updated results for the SCLC cohort of the phase 1/2 CheckMate 032 trial (NCT01928394), which was designed to evaluate nivolumab or nivolumab/ipilimumab in advanced solid tumors.
Methods:
Patients with advanced SCLC that progressed following ≥1 platinum-based chemotherapy regimens were assigned to receive nivolumab monotherapy (nivolumab-3 Q2W) or nivolumab/ipilimumab combination therapy (nivolumab-1/ipilimumab-3 or nivolumab-3/ipilimumab-1 Q3W for 4 cycles, then nivolumab-3 Q2W). Patients were eligible regardless of platinum sensitivity or tumor programmed death ligand 1 (PD-L1) expression. The primary endpoint was ORR. Additional endpoints were duration of response (DOR), OS, PFS, safety, and correlation of tumor PD-L1 expression with activity.
Results:
214 patients have been enrolled to date (nivolumab-3, n=98; nivolumab-1/ipilimumab-3, n=61; nivolumab-3/ipilimumab-1, n=55), including 96 and 118 patients treated with 1 or ≥2 prior regimens, respectively. Efficacy and safety data are shown (table). In the nivolumab-1/ipilimumab-3 cohort, ORR was 23% and 1-year OS was 43%. The proportion of patients with PD-L1–expressing tumors was substantially lower in previously treated SCLC in this study than that previously observed with pretreated NSCLC (16% vs 53%–54% with ≥1% PD-L1 expression). In SCLC, responses were observed regardless of PD-L1 expression. ORR and median OS were similar in patients treated with 1 or ≥2 prior regimens. Rate of discontinuation due to treatment-related AEs ranged from 5% to 11%; there were 3 treatment-related deaths. Figure 1
Conclusion:
Durable objective responses were observed with nivolumab and nivolumab/ipilimumab in patients with previously treated SCLC, and safety profiles were consistent with other tumor types. Updated efficacy (including 2-year OS and DOR), safety, and additional subgroup analyses will be presented from the August 2016 DBL.

OA03.01 - First-Line Nivolumab Monotherapy and Nivolumab plus Ipilimumab in Patients with Advanced NSCLC: Long-Term Outcomes from CheckMate 012 (Abstract under Embargo until December 5, 7:00 CET) (ID 5364)
11:00 - 11:10 | Author(s): M.D. Hellmann
- Abstract
- Presentation
Background:
Nivolumab, a programmed death 1 (PD-1) immune checkpoint inhibitor antibody, has demonstrated improved efficacy and tolerability vs docetaxel in patients with advanced NSCLC that progressed on or after platinum-based chemotherapy and is approved in >50 countries in this patient population. We report efficacy and safety data from a phase 1 study (CheckMate 012; NCT01454102) evaluating first-line nivolumab in patients with advanced NSCLC.
Methods:
Patients (N=52) with advanced, chemotherapy-naive NSCLC (any histology) were treated with nivolumab monotherapy at 3 mg/kg IV Q2W until disease progression or unacceptable toxicity. Safety and tolerability was the primary study objective. Efficacy, as measured by objective response rate (ORR) and 24-week progression-free survival (PFS) rate per RECIST v1.1, was the secondary objective. Overall survival (OS) was an exploratory endpoint.
Results:
Treatment-related adverse events (TRAEs) were reported in 71% (any grade) and 19% (grade 3‒4) of patients. The most frequent select TRAEs (those with potential immunologic causes) by category were skin, endocrine, and gastrointestinal (Table). With a median follow-up of 14.3 months (range, 0.2 to 30.1), the confirmed ORR was 23% (12/52) and 8% (4/52) of patients had complete responses. Of the 12 responses, 8 (67%) were ongoing at the time of database lock; median duration of response was not reached. Median OS was 19.4 months (range, 0.2‒35.8+). The 24-week PFS rate was 41% (95% CI: 27‒54); 18-month OS rate was 57% (95% CI: 42‒70). Updated long-term data will be presented, including 2-year OS and will represent the longest follow-up to date for a PD-1/PD-L1 inhibitor for first-line advanced NSCLC. Updated data from patients treated with nivolumab plus ipilimumab (N = 77) will also be presented.Nivolumab monotherapy (N=52) Safety Any grade / grade 3‒4 TRAEs,[a] n (%) 37 (71) / 10 (19) Any grade / grade 3‒4 select TRAEs,[a,b] by category (≥10% of patients), n (%) Skin 13 (25) / 2 (4) Endocrine 7 (14) / 0 (0) Gastrointestinal 6 (12) / 1 (2) Any grade / grade 3‒4 TRAEs leading to discontinuation, n (%) 6 (12) / 6 (12) Efficacy Confirmed ORR,[c] n (%) [95% CI] 12 (23) [13‒37] CR 4 (8) PR 8 (15) SD 14 (27) PD 20 (38) Unable to determine[d] 6 (12) Median DOR, mo (range) NR (4.2‒25.8+) Ongoing responders, n/N (%) 8/12 (67) Median PFS, mo (range) 3.6 (<0.1+‒28.0+) 24-week PFS, % (95% CI) 41 (27‒54) Median OS, mo (range) 19.4 (0.2‒35.8+) 1-year OS, % (95% CI) 73 (59‒83) 18-month OS, % (95% CI) 57 (42‒70) Efficacy and safety analyses, except for OS, were based on a March 2015 database lock; OS analyses were based on an August 2015 database lock.[a]No grade 5 events were reported.[b]AEs with a potential immunologic cause.[c]Includes patients with initial observations of CR and PR that were subsequently confirmed by repeat scans performed no earlier than 4 weeks after the original observation.[d]Includes patients who discontinued therapy because of disease progression before first assessment or patients only with assessments suggestive of, but that did not satisfy, the required minimum duration for SD.

Conclusion:
First-line nivolumab monotherapy in patients with advanced NSCLC had a similar safety profile as previously reported in second-line NSCLC and other tumors, was well tolerated, and demonstrated durable efficacy.

OA20.01 - Tumor Mutation Burden (TMB) is Associated with Improved Efficacy of Atezolizumab in 1L and 2L+ NSCLC Patients (ID 6149)
11:00 - 11:10 | Author(s): M.D. Hellmann
- Abstract
- Presentation
Background:
In NSCLC, atezolizumab (anti-PDL1) efficacy correlates with PD-L1 expression on tumor cells (TC) and tumor-infiltrating immune cells (IC). Here we examined the association between atezolizumab efficacy and TMB assessed by FoundationOne (F1) sequencing panel.
Methods:
Pretreatment tumor specimens from 102 1L and 465 2L+ NSCLC patients enrolled on three Ph 2 atezolizumab monotherapy trials (POPLAR: randomized 2/3L trial comparing atezolizumab vs docetaxel; BIRCH/FIR: single-arm, 1L/2L+ PD-L1‒selected trials) were available for targeted genetic sequencing using the F1 panel of 315 cancer-related genes. TMB was quantified using an updated TMB algorithm and efficacy was assessed in groups defined by the 75th (high) and 50th (median) percentile of each study-specific TMB. Atezolizumab efficacy was examined at Dec 1, 2015 (POPLAR and BIRCH); and Jan 7, 2015 (FIR) data cutoffs.
Results:
Across samples, median TMB was similar in 1L and 2L+ patients (9/MB and 9.9/MB, respectively). In 1L and 2L+ PD-L1–selected patients, atezolizumab benefit was increased in those with ≥ TMB cut-offs (Table). In unselected 2L+ patients from POPLAR, the OS, PFS, and ORR benefits of atezolizumab vs docetaxel were also enhanced in patients with increased TMB. TMB and PD-L1 expression were independently associated with improved atezolizumab efficacy. TMB associations with PD-L1 expression, tumor-infiltrating lymphocyte infiltration and T-effector cell gene expression will be presented.
Conclusion:
For the first time, we demonstrate that TMB assessed with F1 targeted sequencing is associated with improved atezolizumab outcomes in 1L and 2L+ NSCLC. Moreover, this is the first study demonstrating the association of TMB with improved anti-PD-L1/PD-1 efficacy in a randomized trial. Importantly, the association between TMB and atezolizumab efficacy occurred in both unselected and PD-L1-selected patients. Therefore, in addition to PD-L1, TMB may be an independent predictor of improved responsiveness to atezolizumab in advanced NSCLC.Atezolizumab efficacy by TMB subgroups PD-L1‒selected BIRCH+FIR 1L n=102 2L+n=371 Median (≥9/MB) High (≥13.5/MB) Median (≥9.9/MB) High (≥17.1/MB) OS,HR[a] (95% CI) 0.79 (0.39-1.58) 0.45 (0.17-1.16) 0.87 (0.65-1.16) 0.7 (0.49-1.00) PFS,HR[a] (95% CI) 0.58 (0.36-0.94) 0.54 (0.3-0.97) 0.64 (0.5-0.8) 0.5 (0.38-0.67) ORR,above/below cutoff 28%/13% 25%/20% 25%/14% 29%/16% POPLAR 2L+ unselected n=92 Biomarker- evaluable population Median (≥9.9/MB) High (≥15.8/MB) OS,HR[b ] (95% CI) 0.65 (0.38-1.12) 0.48 (0.23-1.04) 0.5 (0.15-1.67) PFS,HR[b] (95% CI) 0.98 (0.63-1.53) 0.49 (0.25-0.93) 0.49 (0.19-1.3) ORR,atezolizumab/docetaxel 13%/15% 20%/4% 20%/8% [a]HR:efficacy-evaluable patients, atezolizumab at/above cutoff vs below.[b]HR:efficacy-evaluable patients, atezolizumab vs docetaxel at/above cutoff.
