RESUMO
BACKGROUND: Neoadjuvant or adjuvant chemotherapy confers a modest benefit over surgery alone for resectable non-small-cell lung cancer (NSCLC). In early-phase trials, nivolumab-based neoadjuvant regimens have shown promising clinical activity; however, data from phase 3 trials are needed to confirm these findings. METHODS: In this open-label, phase 3 trial, we randomly assigned patients with stage IB to IIIA resectable NSCLC to receive nivolumab plus platinum-based chemotherapy or platinum-based chemotherapy alone, followed by resection. The primary end points were event-free survival and pathological complete response (0% viable tumor in resected lung and lymph nodes), both evaluated by blinded independent review. Overall survival was a key secondary end point. Safety was assessed in all treated patients. RESULTS: The median event-free survival was 31.6 months (95% confidence interval [CI], 30.2 to not reached) with nivolumab plus chemotherapy and 20.8 months (95% CI, 14.0 to 26.7) with chemotherapy alone (hazard ratio for disease progression, disease recurrence, or death, 0.63; 97.38% CI, 0.43 to 0.91; P = 0.005). The percentage of patients with a pathological complete response was 24.0% (95% CI, 18.0 to 31.0) and 2.2% (95% CI, 0.6 to 5.6), respectively (odds ratio, 13.94; 99% CI, 3.49 to 55.75; P<0.001). Results for event-free survival and pathological complete response across most subgroups favored nivolumab plus chemotherapy over chemotherapy alone. At the first prespecified interim analysis, the hazard ratio for death was 0.57 (99.67% CI, 0.30 to 1.07) and did not meet the criterion for significance. Of the patients who underwent randomization, 83.2% of those in the nivolumab-plus-chemotherapy group and 75.4% of those in the chemotherapy-alone group underwent surgery. Grade 3 or 4 treatment-related adverse events occurred in 33.5% of the patients in the nivolumab-plus-chemotherapy group and in 36.9% of those in the chemotherapy-alone group. CONCLUSIONS: In patients with resectable NSCLC, neoadjuvant nivolumab plus chemotherapy resulted in significantly longer event-free survival and a higher percentage of patients with a pathological complete response than chemotherapy alone. The addition of nivolumab to neoadjuvant chemotherapy did not increase the incidence of adverse events or impede the feasibility of surgery.

In the open-label, phase III CheckMate 816 study (NCT02998528), neoadjuvant nivolumab plus chemotherapy demonstrated statistically significant improvements in event-free survival (EFS) and pathological complete response (pCR) versus chemotherapy alone in patients with resectable non-small-cell lung cancer (NSCLC). Here we report efficacy and safety outcomes in the Japanese subpopulation. Patients with stage IB-IIIA, resectable NSCLC were randomized 1:1 to nivolumab plus chemotherapy or chemotherapy alone for three cycles before undergoing definitive surgery within 6 weeks of completing neoadjuvant treatment. The primary end-points (EFS and pCR) and safety were assessed in patients enrolled at 16 centers in Japan. Of the Japanese patients randomized, 93.9% (31/33) in the nivolumab plus chemotherapy arm and 82.9% (29/35) in the chemotherapy arm underwent surgery. At 21.5 months' minimum follow-up, median EFS was 30.6 months (95% confidence interval [CI], 16.8-not reached [NR]) with nivolumab plus chemotherapy versus 19.6 months (95% CI, 8.5-NR) with chemotherapy; hazard ratio, 0.60 (95% CI, 0.30-1.24). The pCR rate was 30.3% (95% CI, 15.6-48.7) versus 5.7% (95% CI, 0.7-19.2), respectively; odds ratio, 7.17 (95% CI, 1.44-35.85). Grade 3/4 treatment-related adverse events were reported in 59.4% versus 42.9% of patients, respectively, with no new safety signals identified. Neoadjuvant nivolumab plus chemotherapy resulted in longer EFS and a higher pCR rate versus chemotherapy alone in Japanese patients, consistent with findings in the global population. These data support nivolumab plus chemotherapy as a neoadjuvant treatment option in Japanese patients with resectable NSCLC.

WHAT IS THIS SUMMARY ABOUT?: In this article, we summarize results from the ongoing phase 3 CheckMate 816 clinical study that were published in The New England Journal of Medicine in 2022. The goal of CheckMate 816 was to find out if nivolumab, an immunotherapy that activates a person's immune system (the body's natural defense system) to fight cancer, plus chemotherapy works better than chemotherapy alone when given before surgery in people with non-small-cell lung cancer (NSCLC) that can be removed surgically (resectable NSCLC). WHAT HAPPENED IN THE STUDY?: Adults who had not previously taken medications to treat NSCLC and whose cancer could be removed with surgery were included in CheckMate 816. During this study, a computer randomly assigned the treatment each person would receive before surgery for NSCLC. In total, 179 people were randomly assigned to receive nivolumab plus chemotherapy, and 179 people were randomly assigned to receive chemotherapy alone. The researchers assessed whether people who received nivolumab plus chemotherapy lived longer without the cancer geting worse or coming back and whether there were any cancer cells left in the tumor and lymph nodes removed by surgery. The researchers also assessed how adding nivolumab to chemotherapy affected the timing and outcomes of surgery and whether the combination of these drugs was safe. WHAT WERE THE RESULTS?: Researchers found that people who took nivolumab plus chemotherapy lived longer without the cancer getting worse or coming back compared with those who took chemotherapy alone. More people in the nivolumab plus chemotherapy group had no cancer cells left in the tumor and lymph nodes removed by surgery. Most people went on to have surgery in both treatment groups; the people who took nivolumab plus chemotherapy instead of chemotherapy alone had less extensive surgeries and were more likely to have good outcomes after less extensive surgeries. Adding nivolumab to chemotherapy did not lead to an increase in the rate of side effects compared with chemotherapy alone, and side effects were generally mild and manageable. WHAT DO THE RESULTS OF THE STUDY MEAN?: Results from CheckMate 816 support the benefit of using nivolumab plus chemotherapy before surgery for people with resectable NSCLC.

Neoadjuvant immunotherapy plus chemotherapy improves event-free survival (EFS) and pathologic complete response (0% residual viable tumor (RVT) in primary tumor (PT) and lymph nodes (LNs)), and is approved for treatment of resectable lung cancer. Pathologic response assessment after neoadjuvant therapy is the potential analog to radiographic response for advanced disease. However, %RVT thresholds beyond pathologic complete response and major pathologic response (≤10% RVT) have not been explored. Pathologic response was prospectively assessed in the randomized, phase 3 CheckMate 816 trial (NCT02998528), which evaluated neoadjuvant nivolumab (anti-programmed death protein 1) plus chemotherapy in patients with resectable lung cancer. RVT, regression and necrosis were quantified (0-100%) in PT and LNs using a pan-tumor scoring system and tested for association with EFS in a prespecified exploratory analysis. Regardless of LN involvement, EFS improved with 0% versus >0% RVT-PT (hazard ratio = 0.18). RVT-PT predicted EFS for nivolumab plus chemotherapy (area under the curve = 0.74); 2-year EFS rates were 90%, 60%, 57% and 39% for patients with 0-5%, >5-30%, >30-80% and >80% RVT, respectively. Each 1% RVT associated with a 0.017 hazard ratio increase for EFS. Combining pathologic response from PT and LNs helped differentiate outcomes. When compared with radiographic response and circulating tumor DNA clearance, %RVT best approximated EFS. These findings support pathologic response as an emerging survival surrogate. Further assessment of the full spectrum of %RVT in lung cancer and other tumor types is warranted. ClinicalTrials.gov registration: NCT02998528 .

INTRODUCTION: The 5 year survival rate for patients with locally advanced non-small-cell lung cancer (NSCLC) not amenable for definitive resection with historical standard-of-care concurrent chemoradiotherapy (cCRT) ranges from 15% to 32%. cCRT primes anti-tumor immunity and also upregulates programmed death ligand-1 (PD-L1), providing a rationale for combining an immune checkpoint inhibitor with cCRT to improve outcomes. In the PACIFIC trial, consolidation therapy with the PD-L1 inhibitor durvalumab improved progression-free survival (PFS) and overall survival (OS) vs. placebo in patients with stage III NSCLC who did not have disease progression after cCRT. CheckMate73L (NCT04026412), a randomized phase 3 study, evaluates the efficacy of nivolumab plus cCRT followed by nivolumab with or without ipilimumab vs. cCRT followed by durvalumab for untreated, stage III NSCLC. PATIENTS AND METHODS: Patients with untreated, stage III NSCLC will be randomized 1:1:1 to nivolumab plus cCRT followed by nivolumab in combination with ipilimumab (Arm A) or nivolumab alone (Arm B); or cCRT followed by durvalumab (Arm C). Primary endpoints are PFS and OS (Arm A vs. Arm C). Secondary endpoints include additional analyses of PFS and OS (Arm A vs. Arm B; Arm B vs. Arm C), as well as objective response rate, complete response rate, time to response, duration of response, time to death or distant metastases, and safety and tolerability. Recruitment began on August 20, 2019, and the estimated primary completion date is October 17, 2022.

BACKGROUND: We explored whether the effectiveness of immune checkpoint inhibitors (ICIs) can be characterized by incorporating a composite of duration of response (DOR) to complement traditional Response Evaluation Criteria in Solid Tumors (RECIST) criteria for objective response rate (ORR) in an intent-to-treat (ITT) population. Furthermore, the correlation of this novel endpoint, characterized by the restricted mean time in response (RMTR), with overall survival (OS) will be examined. METHODS: We analyzed ORR alone or in combination with DOR (RMTR) in available phase I, II, and III trials evaluating nivolumab monotherapy or in combination with ipilimumab across solid tumor types. ORR was evaluated per RECIST V.1.1. DOR was estimated using individual patient data in ITT populations regardless of RECIST response, with non-responders imputed as zero. Associations between ORR alone or RMTR and OS were evaluated in the ITT population. DOR curves were generated using the Kaplan-Meier product limit method, and 6-month RMTR, a measure of response durability, was derived from the area under the curves. For ORR and RMTR in the ITT population, the strength of association with OS was analyzed using Pearson correlation coefficients (r). RESULTS: Nivolumab treatment was associated with longer response durations than active control in responder and ITT populations. Similarly, ORR and RMTR were both significantly correlated with OS (ORR vs OS: r=0.684, p=0.02; RMTR vs OS: r=0.695, p=0.018). CONCLUSIONS: Combining ORR and DOR (RMTR) to objectively characterize tumor shrinkage in an ITT patient population is a novel approach that appears to correlate well with OS in patients treated with nivolumab monotherapy or in combination with ipilimumab. This endpoint may provide a more complete characterization of tumor shrinkage to incorporate into the design of future ICI clinical trials. However, confirmation of this approach will require further research.

Nivolumab is the first anti-programmed death-1 agent approved in China for treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC). Here, we characterize the population pharmacokinetics (PPK) of nivolumab monotherapy in Chinese patients with previously treated advanced/recurrent solid tumors, including NSCLC and nasopharyngeal cancer (NPC), using data from 2 predominantly Chinese (CheckMate 077 and 078), and 5 global (MDX1106-01, CA209-003, and CheckMate 017, 057, and 063) studies. The PPK model was developed by reestimating parameters of a prior global population model with Chinese patient data. Model reestimates showed nivolumab pharmacokinetics (PK) to be linear and dose proportional. Race did not have a clinically meaningful effect on nivolumab clearance. Body weight, Asian race, sex, and performance status had significant effects on clearance. Baseline clearance was 9% lower in the Asian versus the global population but not considered clinically relevant. Change in time-varying clearance and predicted nivolumab exposures with 3 mg/kg every 2 weeks (Q2W) were similar in Chinese, non-Chinese Asian, and non-Asian patients. In Chinese patients, the predicted nivolumab exposure with a 240-mg Q2W regimen was â¼25% higher than with 3 mg/kg Q2W, but â¼62% lower than that of a previously evaluated, well-tolerated regimen of 10 mg/kg Q2W (global population). Differences in nivolumab baseline clearance and exposures between patients with NPC and NSCLC were not clinically meaningful (<20%). Overall, PPK analysis demonstrated that nivolumab was not sensitive to race when evaluated in Chinese and non-Asian patients and exhibited similar PK in NSCLC and NPC.

INTRODUCTION: Data on immuno-oncology agents in Chinese patients are limited despite a need for new therapies. We evaluated the efficacy and safety of nivolumab in a predominantly Chinese patient population with previously treated NSCLC. METHODS: CheckMate 078 was a randomized, open-label, phase III clinical trial in patients from China, Russia, and Singapore with squamous or nonsquamous NSCLC that had progressed during/after platinum-based doublet chemotherapy (ClinicalTrials.gov: NCT02613507). Patients with EGFR/ALK alterations were excluded. Patients (N = 504) were randomized 2:1 to nivolumab (3 mg/kg every 2 weeks) or docetaxel (75 mg/m2 every 3 weeks), stratified by performance status, tumor histology, and tumor programmed death ligand 1 expression. The primary endpoint was overall survival (OS); secondary endpoints included objective response rate, progression-free survival, and safety. RESULTS: OS was significantly improved with nivolumab (n = 338) versus docetaxel (n = 166); median OS (95% confidence interval): 12.0 (10.4-14.0) versus 9.6 (7.6-11.2) months, respectively; hazard ratio (97.7% confidence interval): 0.68 (0.52-0.90); p = 0.0006. Objective response rate was 17% with nivolumab versus 4% with docetaxel; median duration of response was not reached versus 5.3 months. Minimum follow-up was 8.8 months. The frequency of grade 3 or greater treatment-related adverse events was 10% with nivolumab and 48% with docetaxel. CONCLUSIONS: This is the first phase III study in a predominantly Chinese population reporting results with a programmed death 1 inhibitor. In this population with previously treated advanced NSCLC, nivolumab improved OS versus docetaxel. Results were consistent with global CheckMate 017 and 057 studies.

BACKGROUND: The purpose of this study was to assess the efficacy, safety, and pharmacokinetics of cisplatin-based chemotherapy plus cetuximab as first-line treatment in Chinese and Korean patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). METHODS: Patients (n = 68) received cetuximab weekly plus 3-week cycles of cisplatin/5-fluorouracil (5-FU) chemotherapy for up to 6 cycles. The primary endpoint was overall response rate. RESULTS: The overall response rate was 55.9%, including 2 complete responses (CRs). Median overall survival (OS) was 12.6 months and median progression-free survival (PFS) was 6.6 months. Grade 3/4 adverse events (AEs) were reported in 41 (60.3%) patients. The safety profile was in line with previous clinical experience. The pharmacokinetic profile was in line with that observed with cetuximab in white and Japanese patients. CONCLUSION: The efficacy, safety, and pharmacokinetic findings from this study support the use of first-line platinum-based chemotherapy plus cetuximab in Chinese and Korean patients with recurrent and/or metastatic SCCHN (ClinicalTrials.gov NCT01177956).

In general, focal nodular hyperplasia lesions of the liver have a benign natural course; the majority of cases remain asymptomatic and complications are rare. We report a case of spontaneous rupture and hemorrhage of focal nodular hyperplasia, which is extremely rare in the literature. A 35-year-old woman was admitted with severe upper abdominal pain and unstable hemodynamic status. No major abdominal trauma was noted. Radiology findings suggested a diffuse hemoperitoneum. Emergent surgical exploration showed a hemoperitoneum due to the rupture of a hepatic mass lesion in segment I. Suture of the rupture was undertaken with success. After this lifesaving emergent surgery, further investigations, including ultrasound, contrast-enhanced computed tomography, and magnetic resonance imaging, were undertaken, and a 5.7 x 9.8 x 6.4-cm focal nodular hyperplasia lesion was identified in segment I. Two weeks after the first surgical hemostasis, surgical removal of segment I, including the mass, was performed. The postoperative course was uneventful. Pathological evaluation confirmed the nature of focal nodular hyperplasia. The patient remains asymptomatic without evidence of recurrence 3 years and 6 months after surgery. To our knowledge, this is the firstcase of spontaneous rupture and hemorrhage of focal nodular hyperplasia that needed two consecutive surgical operations.
