Randomized Controlled Trial
Pembrolizumab plus pemetrexed-platinum significantly improved overall survival (OS) and progression-free survival (PFS) with manageable safety compared with placebo plus pemetrexed-platinum in patients with previously untreated metastatic nonsquamous non-small-cell lung cancer (NSCLC) without EGFR/ALK alterations in the global, randomized, double-blind, phase 3 KEYNOTE-189 study. We present results of Japanese patients enrolled in the KEYNOTE-189 global and Japan extension studies. Patients were randomized 2:1 to intravenous pembrolizumab 200 mg or placebo every 3 weeks (Q3W) for up to 35 cycles. All patients received pemetrexed 500 mg/m plus the investigator's choice of cisplatin or carboplatin Q3W for four cycles, followed by maintenance pemetrexed 500 mg/m Q3W (all intravenous). Co-primary endpoints were OS and PFS. Forty Japanese patients enrolled (pembrolizumab, n = 25; placebo, n = 15). At data cutoff (20 May 2019; median time from randomization to data cutoff, 18.5 [range, 14.7-38.2] months), the median OS was not reached in the pembrolizumab plus pemetrexed-platinum arm; the median OS was 25.9 (95% confidence interval [CI], 11.9-29.0) months in the placebo plus pemetrexed-platinum arm (hazard ratio [HR] .29; 95% CI, .07-1.15). The median (95% CI) PFS was 16.5 (8.8-21.1) compared with 7.1 (4.7-21.4) months (HR, .62; 95% CI, .27-1.42), respectively. There were no grade 5 adverse events (AE). Grade 3/4 AE occurred in 72% vs 60% of patients in the pembrolizumab vs placebo arms; 40% vs 20% had immune-mediated AE, and 4% vs 0% had infusion reactions. Efficacy and safety outcomes were similar to those from the global study and support first-line therapy with pembrolizumab plus pemetrexed-platinum in Japanese patients with nonsquamous NSCLC without EGFR/ALK alterations.

Randomized Controlled Trial
Final overall survival data of sintilimab plus pemetrexed and platinum as First-Line treatment for locally advanced or metastatic nonsquamous NSCLC in the Phase 3 ORIENT-11 study.
OBJECTIVES
In ORIENT-11, first-line sintilimab + pemetrexed-platinum significantly improved PFS compared with placebo + pemetrexed-platinum in patients with advanced metastatic nonsquamous non-small-cell lung cancer (AMnsqNSCLC). The study met the primary endpoint of PFS as of 15November2019. Here we report final survival analysis from ORIENT-11 (NCT03607539) using a 15September2021 data cutoff.
METHODS
Patients with treatment-naïve locally AMnsqNSCLC without sensitizing EGFR or ALK genomic tumor aberrations were randomly assigned to sintilimab + pemetrexed-platinum (n = 266) or placebo + pemetrexed-platinum (n = 131). Patients were stratified by PD-L1 expression, platinum-chemotherapy, and gender. Treatment continued until PD, unacceptable toxicity, or a maximum of 24 months. Patients in the placebo + pemetrexed-platinum arm could be sequenced to second-line sintilimab monotherapy, contingent upon PD. Response was assessed (RECISTv.1.1) by blinded independent radiographic review committee. Primary endpoint was PFS. OS was a secondary endpoint and defined from date of randomization to date of death due to any cause. Final OS analysis was defined as approximately 2 years after last patient randomized or when approximately 65 % of patients died, whichever first.
RESULTS
At data cutoff of final OS analysis, median study follow-up was 30.8 months. Of 397 patients, 243 OS events were observed (sintilimab + pemetrexed-platinum:151[57 %];placebo + pemetrexed-platinum:92 [70 %]). Of the patients in placebo + pemetrexed-platinum arm, 47 % crossed over to sintilimab monotherapy per protocol. Median OS was 24.2 months in sintilimab + pemetrexed-platinum arm and 16.8 months in placebo + pemetrexed-platinum arm (HR:0.65[95 % CI:0.50,0.85]). Estimated 2-year OS rates were 50 %(sintilimab + pemetrexed-platinum) and 32 %(placebo + pemetrexed-platinum). After adjusting for the crossover effect, OS treatment effect was more pronounced with HR 0.52 (95 % CI:0.38,0.69). OS benefit across all prespecified subgroups was largely consistent with that observed in the ITT population.
CONCLUSIONS
In the ORIENT-11 final OS analysis, sintilimab + pemetrexed-platinum demonstrated improved OS compared to placebo + pemetrexed-platinum when administered as first-line therapy in AMnsqNSCLC without EGFR or ALK genomic tumor aberrations.

Randomized Controlled Trial
INTRODUCTION
In CameL phase 3 study (ClinicalTrials.gov: NCT03134872), addition of camrelizumab to first-line chemotherapy significantly improved the progression-free survival in patients with stages IIIB to IV nonsquamous NSCLC. Here, we present outcomes after a minimum follow-up of 43.9 months since last patient randomization.
METHODS
Eligible patients were randomized 1:1 to 4 to 6 cycles of camrelizumab plus carboplatin and pemetrexed or chemotherapy alone every 3 weeks, followed by maintenance camrelizumab plus pemetrexed or pemetrexed only (n = 205 and 207, respectively). Total camrelizumab exposure was up to 2 years.
RESULTS
As of January 31, 2022, camrelizumab plus chemotherapy exhibited substantially improved overall survival over chemotherapy alone (median, 27.1 versus 19.8 mo; hazard ratio = 0.72 [95% confidence interval: 0.57-0.92]). In the chemotherapy-alone group, 95 patients (45.9%) crossed over to camrelizumab monotherapy. After adjustment for crossover, the survival benefit with camrelizumab plus chemotherapy was more pronounced (adjusted hazard ratio = 0.55 [95% confidence interval: 0.42-0.71]). In camrelizumab plus chemotherapy group, 33 patients completed 2 years of camrelizumab. Objective response rate was 97.0%, with ongoing responses in 17 of the 32 responses (53.1%), and 93.9% (31 of 33) of the patients were alive at data cutoff. Safety profiles were consistent with the previous report, and no obvious evidence of cumulative toxicity was found with long exposure to camrelizumab.
CONCLUSIONS
Camrelizumab plus carboplatin and pemetrexed provides long-term survival benefit over chemotherapy, with manageable toxicity and remarkable and durable response in patients receiving 2 years of camrelizumab, further supporting camrelizumab combination as first-line treatment for advanced nonsquamous NSCLC.

Efficacy and Safety of Intrathecal Pemetrexed Combined With Dexamethasone for Treating Tyrosine Kinase Inhibitor-Failed Leptomeningeal Metastases From EGFR-Mutant NSCLC-a Prospective, Open-Label, Single-Arm Phase 1/2 Clinical Trial (Unique Identifier: ChiCTR1800016615).
INTRODUCTION
We aimed to evaluate the efficacy and safety of intrathecal pemetrexed (IP) for treating EGFR-mutant leptomeningeal metastases (LMs) from EGFR-mutant NSCLC.
METHODS
Patients with EGFR-mutant NSCLC with LM who had failed tyrosine kinase inhibitors were recruited. The dose of IP was escalated from 15 mg to 80 mg using an accelerated titration design in a phase 1 study. The recommended dose (RD) determined in phase 1 was used in the phase 2 study. The primary end point was treatment efficacy measured as the clinical response rate. Overall survival and adverse events (AEs) were evaluated as secondary end points.
RESULTS
The RD observed in the phase 1 study was 50 mg pemetrexed. A total of 30 cases of LM-NSCLC were enrolled in the phase 2 study, including 14 males and 16 females. Four patients did not survive for 4 weeks and could not be evaluated for efficacy. The clinical response rate was 84.6% (22 of 26). The median overall survival of all patients was 9.0 months (n = 30, 95% confidence interval: 6.6-11.4 mo). Most AEs were mild, and the most frequent AE of any grade was myelosuppression (n = 9, 30%), which returned to normal after symptomatic treatment.
CONCLUSIONS
This study revealed that 50 mg pemetrexed is the RD which results in few AEs and a good response rate. IP is an effective treatment for patients with EGFR-mutant NSCLC-LM who had failed on tyrosine kinase inhibitor.

Randomized Controlled Trial
INTRODUCTION
In cohort G of KEYNOTE-021 (NCT02039674), first-line pembrolizumab plus pemetrexed-carboplatin significantly improved the objective response rate and progression-free survival versus chemotherapy alone with manageable toxicity in advanced nonsquamous NSCLC. We report the long-term outcomes from this study.
METHODS
Patients with previously untreated advanced nonsquamous NSCLC without sensitizing EGFR or ALK alterations were randomly assigned 1:1 to receive open-label pemetrexed 500 mg/m plus carboplatin at area under the concentration-time curve of 5 mg/mL/min (four cycles) with or without pembrolizumab 200 mg (up to 2 years), with optional pemetrexed maintenance, each administered every 3 weeks. Eligible patients could crossover from the chemotherapy arm to pembrolizumab monotherapy after progression. Responses were assessed per the Response Evaluation Criteria in Solid Tumors version 1.1.
RESULTS
After the median time of 49.4 months from randomization to data cutoff, objective response rate (58% versus 33%) and progression-free survival (median: 24.5 versus 9.9 mo; hazard ratio: 0.54; 95% confidence interval: 0.35‒0.83) remained improved with pembrolizumab combination (n = 60) versus chemotherapy (n = 63), regardless of programmed death ligand 1 status. Median overall survival was 34.5 versus 21.1 months (hazard ratio: 0.71; 95% confidence interval: 0.45‒1.12), despite a 70% crossover rate from chemotherapy alone to anti‒programmed death (ligand) 1 therapy. Among the 12 patients who completed 2 years of pembrolizumab, 92% were alive at data cutoff; the estimated 3-year duration of response rate was 100%. Grade 3 to 5 treatment-related adverse events occurred in 39% of patients receiving pembrolizumab combination and 31% receiving chemotherapy.
CONCLUSIONS
First-line pembrolizumab plus pemetrexed-carboplatin continued to show improved response and survival versus chemotherapy alone in advanced nonsquamous NSCLC, with durable clinical benefit in patients who completed 2 years of therapy. No new safety signals were observed with longer follow-up.

Phase II Trial of Atezolizumab Combined With Carboplatin and Pemetrexed for Patients With Advanced Nonsquamous Non-Small-Cell Lung Cancer With Untreated Brain Metastases (Atezo-Brain, GECP17/05).
PURPOSE
The Atezo-Brain study evaluated atezolizumab combined with chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC) with untreated brain metastases, a population traditionally excluded from trials.
METHODS
This single-arm phase II clinical trial enrolled patients with advanced nonsquamous NSCLC with untreated brain metastases without neurologic symptoms or asymptomatic with medical treatment. Dexamethasone was allowed up to 4 mg once daily. Atezolizumab plus carboplatin and pemetrexed was given for four to six cycles followed by atezolizumab plus pemetrexed until progression for a maximum of 2 years. The primary end points were to determine the progression-free survival (PFS) rate at 12 weeks and the incidence of grade ≥3 adverse events during the first 9 weeks. Intracranial outcomes were assessed using response assessment in neuro-oncology brain metastases criteria.
RESULTS
Forty patients were enrolled and 22 (55%) were receiving corticosteroids at baseline. The overall 12-week PFS rate was 62.2% (95% credibility interval [CrI], 47.1 to 76.2). The rate of grade 3/4 adverse events during the first 9 weeks was 27.5%. Most neurologic events were grade 1 and 2 but five patients (12.5%) experienced grade 3-4 neurologic events. With a median follow-up of 31 months, intracranial median PFS was 6.9 months and response rate was 42.7% (95% CrI, 28.1 to 57.9). Systemic median PFS was 8.9 months and response rate was 45% (95% CrI, 28.1 to 57.9). The median overall survival (OS) was 11.8 months (95% CI, 7.6 to 16.9) and the 2-year OS rate was 27.5% (95% CI, 16.6 to 45.5).
CONCLUSION
Atezolizumab plus carboplatin and pemetrexed demonstrates activity in patients with advanced nonsquamous NSCLC with untreated brain metastases with an acceptable safety profile.

PURPOSE
To evaluate the efficacy of pemetrexed plus cisplatin versus vinorelbine plus cisplatin as postoperative adjuvant chemotherapy in patients with pathologic stage II-IIIA nonsquamous non-small-cell lung cancer (NSCLC).
PATIENTS AND METHODS
We performed a randomized, open-label, phase III study at 50 institutions within 7 clinical study groups in Japan. Patients with completely resected pathologic stage II-IIIA (TNM 7th edition) nonsquamous NSCLC were randomly assigned to receive either pemetrexed (500 mg/m, day 1) plus cisplatin (75 mg/m, day 1) or vinorelbine (25 mg/m, days 1 and 8) plus cisplatin (80 mg/m, day 1) with stratification by sex, age, pathologic stage, mutation, and institution. These treatments were planned to be given every 3 weeks for 4 cycles. The primary end point was recurrence-free survival in the modified intent-to-treat population, excluding ineligible patients.
RESULT
Between March 2012 and August 2016, 804 patients were enrolled (402 assigned to vinorelbine plus cisplatin and 402 assigned to pemetrexed plus cisplatin). Of 784 eligible patients, 410 (52%) had stage IIIA disease and 192 (24%) had -sensitive mutations. At a median follow-up of 45.2 months, median recurrence-free survival was 37.3 months for vinorelbine plus cisplatin and 38.9 months for pemetrexed plus cisplatin, with a hazard ratio of 0.98 (95% CI, 0.81 to 1.20; 1-sided = .474). Grade 3-4 toxicities reported more frequently for vinorelbine plus cisplatin than for pemetrexed plus cisplatin were febrile neutropenia (11.6% 0.3%, respectively), neutropenia (81.1% 22.7%, respectively), and anemia (9.3% 2.8%, respectively). One treatment-related death occurred in each arm.
CONCLUSION
Although this study failed to show the superiority of pemetrexed plus cisplatin for patients with resected nonsquamous NSCLC, this regimen showed a better tolerability as adjuvant chemotherapy.

BACKGROUND
Resistance to pemetrexed (PEM), a rare chemotherapeutic agent that can efficiently cross the blood-brain barrier, limits the therapeutic efficacy for patients with lung cancer brain metastasis (BM). Aldo-keto reductase family 1 B10 (AKR1B10) was recently found to be elevated in lung cancer BM. The link between AKR1B10 and BM-acquired PEM is unknown.
METHODS
PEM drug-sensitivity was assessed in the preclinical BM model of PC9 lung adenocarcinoma cells and the BM cells with or without AKR1B10 interference in vitro and in vivo. Metabolic reprogramming of BM attributed to AKR1B10 was identified by chromatography-mass spectrometry (GC-MS) metabolomics, and the mechanism of how AKR1B10 mediates PEM chemoresistance via a way of modified metabolism was revealed by RNA sequencing as well as further molecular biology experimental approaches.
RESULTS
The lung cancer brain metastatic subpopulation cells (PC9-BrM3) exhibited significant resistance to PEM and silencing AKR1B10 in PC9-BrM3 increased the PEM sensitivity in vitro and in vivo. Metabolic profiling revealed that AKR1B10 prominently facilitated the Warburg metabolism characterized by the overproduction of lactate. Glycolysis regulated by AKR1B10 is vital for the resistance to PEM. In mechanism, AKR1B10 promoted glycolysis by regulating the expression of lactate dehydrogenase (LDHA) and the increased lactate, acts as a precursor that stimulates histone lactylation (H4K12la), activated the transcription of CCNB1 and accelerated the DNA replication and cell cycle.
CONCLUSIONS
Our finding demonstrates that AKR1B10/glycolysis/H4K12la/CCNB1 promotes acquired PEM chemoresistance in lung cancer BM, providing novel strategies to sensitize PEM response in the treatment of lung cancer patients suffering from BM.

Randomized Controlled Trial
Advanced medical care is a system that allows the use of off-label treatments in conjunction with insurance reimbursement, and is used for clinical trials to evaluate off-label treatments. Since pemetrexed has been not approved for patients with resected non-small cell lung cancer(NSCLC)in Japan, we conducted the randomized phase Ⅲ study(JIPANG)to evaluate the efficacy of pemetrexed plus cisplatin versus vinorelbine plus cisplatin as adjuvant chemotherapy in patients with stage Ⅱ-ⅢA nonsquamous NSCLC. This study needed 5-year registration period, and 5-year follow-up after registration of the last patient. The JIPANG study failed to show the superiority of pemetrexed plus cisplatin in terms of recurrence-free survival, as primary endpoint. In Japan, the challenges in conducting academia-led clinical trials of unapproved drugs and drugs for off-label use are the establishment of a system for conducting trials, the provision of drugs, and the procurement of funds.
