BackgroundMore clinical practice need to be performed to verify the toxicity of the hypofractionated radiotherapy (HFRT) combined with PD-1 blockade in lung cancer. This phase I study aimed to investigate the safety and efficacy of nivolumab combined with HFRT in patients with progressive advanced lung cancer following multiline treatment.MethodsWe enrolled 31 patients with advanced lung cancer pathologically confirmed to have progressive disease and treated with first-line or a higher therapy. Selected lesions were treated using HFRT, and nivolumab was administered within 7 days subsequently. Nivolumab was administered once a month following partial remission. Peripheral blood was collected before and after 1 month of treatment to evaluate relevant cytokines between nivolumab responders and non-responders.ResultsOverall, 23 patients who completed the treatment were evaluated. Of them, 9 and 14 patients underwent hypofractionated brachytherapy with 30 Gy in a single fraction via percutaneous interstitial implantation of (192)Ir and 40–50 Gy in 5 fractions via stereotactic body radiation therapy, respectively. The median follow-up period was 11 months. At the 1-year follow-up, no patient developed grade ≥ 3 pneumonitis. The overall objective response and complete remission rates were 39.13% and 13.04%, respectively. The 1-year overall survival and median progression-free survival were 60.9% and 6 months, respectively. The plasma levels of interleukin IL-6, IL-10, and IL-17A were significantly reduced after treatment in nivolumab responders.ConclusionsHFRT could increase the responsivity to nivolumab and reduce its administration frequency. This combination treatment is well tolerated with acceptable toxicity and thus merits further trials to validate benefits.Clinical Trial Registrationhttp://www.chictr.org.cn/index.aspx, identifier ChiCTR-1900027768.

e19029 Background: We previously conducted a phase I trial of combination chemotherapy with irinotecan and amrubicin for NSCLC and found acceptable toxicity profiles with a favorable efficacy in patients with pretreated NSCLC. The aim of this phase II trial was to further evaluate its efficacy and toxicity in this population with a long-term follow-up. Methods: Primary endpoint was objective response. Patients with NSCLC previously treated with one or two chemotherapy regimens were enrolled in this trial. Irinotecan and amrubicin were both administered on days 1 and 8, every 3 weeks at doses of 100 and 40 mg/m2, respectively. Response and toxicity were assessed according to the RECIST guideline and NCI-CTC for AE v3.0. Results: Thirty-one pretreated NSCLC patients were enrolled between 2004 and 2006. A median number of courses administered was 3 (range: 1 to 6). All patients and courses were assessable for efficacy and safety. Demographics of the patients were as follows: M/F:21/10, Ad/others:21/10, ECOG-PS 0/1:12/19, and smoker/non-smoker:21/10. Platinum-based regimens were commonly used as the prior chemotherapy. Objective response was obtained in 9 of the 31 patients with a response rate of 29.0% (95%CI: 12.1–46.0%). Grade 4 leukopenia and neutropenia were observed in 6 (19%) and 14 (45%) patients, respectively, whereas thrombocytopenia were generally mild. Grade 3 febrile neutropenia was observed in 7 patients (23%), of whom two patients further developed Grade 4 and 5 septic shock each. Other grade 3 or greater non-hematological toxicities included diarrhea, vomiting, pneumonitis, liver dysfunction in 4, 1, 1 and 2 patients, respectively. With a median follow-up time of 24.2 months, median survival time and median progression-free survival time were 14.2 and 4.0 months, respectively. Conclusions: This combination seemed highly effective for pretreated NSCLC with an acceptable toxicity. No significant financial relationships to disclose.

9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified.

4040 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI had robust, durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (median follow-up 13.8 months [mo; range, 9–19]; Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up is presented here. Methods: Patients (pts) with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg Q2W + low-dose IPI 1 mg/kg Q6W until disease progression or discontinuation. The primary endpoint was investigator-assessed (INV) objective response rate (ORR) per RECIST v1.1. Results: In 45 pts with median follow-up of 29.0 mo, ORR (95% CI) increased to 69% (53–82) (Table) from 60% (44.3–74.3); complete response (CR) rate increased to 13% from 7%. The concordance rate of INV and blinded independent central review was 89%. Median duration of response (DOR) was not reached (Table). Median progression-free survival (PFS) and overall survival (OS) were not reached, and 24-mo rates were 74% and 79%, respectively (Table). Nineteen pts discontinued study treatment without subsequent therapy. An analysis of tumor response post discontinuation will be presented. Ten (22%) pts had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had grade 3–4 TRAEs leading to discontinuation. Conclusions: NIVO + low-dose IPI continued to show robust, durable clinical benefit with a deepening of response, and was well tolerated with no new safety signals identified with longer follow-up. NIVO + low-dose IPI may represent a new 1L therapy option for pts with MSI-H/dMMR mCRC. Clinical trial information: NTC02060188 . [Table: see text]

Incidence And Mortality

Abstract Background The high incidence and mortality of lung cancer have seriously affected human life and health. Nivolumab is a monoclonal antibody that can inhibit programmed death 1 (PD-1) and Ipilimumab is a monoclonal antibody against CTLA-4(cytotoxic T lymphocyte-associated antigen 4), both of which can prevent the immune escape of tumor cells. Our goal was to synthesize evidence from published randomized controlled trials involving the safety and efficacy of either Nivolumab alone or in combination for the treatment of unresectable lung cancer. Methods We searched the following electronic databases: PubMed, Embase, and Cochrane libraries, and screened the retrieved records for eligibility. We used the Stata16 software for the analyses. The results of the analysis are expressed as hazard ratios (HRs) or risk ratios (RRs) and their corresponding 95% confidence intervals (CI). Results The final analysis included seven trials involving 3817 patients. Among patients with advanced lung cancer, patients using immunotherapy had better overall survival (OS), progression-free survival (PFS), and an objective response rate (ORR) than patients receiving chemotherapy. The HR of Nivolumab monotherapy or combination therapy with OS was compared with that of chemotherapy (HR: 0.73, 95% CI 0.64–0.83; HR: 0.67, 95% CI 0.55–0.81), and the HR of PFS was (HR: 0.81, 95% CI 0.69–0.94; HR: 0.67, 95% CI 0.55–0.82). Conclusions Immunotherapy has been shown to have more clinically meaningful survival benefits for patients with lung cancer, whether monotherapy or combination immunotherapy. CRD42020213440

Abstract Background S-1 plus cisplatin is a standard chemotherapy regimen for advanced non-small cell lung cancer (NSCLC). The addition of bevacizumab has been shown to significantly improve overall survival (OS) in patients with advanced non-squamous (NSq) NSCLC who received carboplatin plus paclitaxel, however, failed to show an OS advantage in patients who received cisplatin plus gemcitabine. Methods Chemotherapy-naive patients with Stage IIIB, IV or recurrent non-SQ NSCLC were treated with a 3-week cycle of S-1 80 mg/m2 on days 1–14, cisplatin 60 mg/m2 on day 8 and bevacizumab 15 mg/kg on day 8 for 4–6 cycles. Patients without progressive disease (PD) received maintenance bevacizumab 15 mg/kg on day 1 with a 3-week cycle and S-1 80 mg/m2 every other day. The primary endpoint was progression-free survival (PFS). Secondary endpoints were objective response rate (ORR), OS, toxicity profile and Quality of life (QOL). Results From June 2013 to January 2015, 39 eligible patients were enrolled from eight institutions. Thirty-one patients (79%) completed four cycles of induction chemotherapy, and maintenance chemotherapy was initiated in 23 patients (59%). Median PFS, OS and ORR were 7.3 months (95% CI: 5.9–8.7), 21.4 months (95% CI: 14.7—not reached) and 64%, respectively. The most common grade 3/4 toxicities were leukopenia (12.8%), neutropenia (23.0%) and hypertension (28.2%). QOL analyses showed detrimental effects after initiation of the regimen. Conclusions S-1 plus cisplatin in combination with bevacizumab met the primary endpoint in patients with advanced NSq-NSCLC. RR was anticipated to be high with acceptable toxicities.

8527 Background: It is unknown which regimen is the best in concurrent chemoradiotherapy (CCRT) of locally advanced non-squamous non-small cell lung cancer (NSCLC). Our previous randomized phase Ⅱ study, NJLCG0601, showed that chemoradiotherapy with uracil/tegafur (UFT) and cisplatin achieved promising efficacy with acceptable toxicities. In this trial, this regimen was compared to a regimen with pemetrexed and cisplatin for stage Ⅲ non-squamous NSCLC. Methods: Patients with inoperable stage Ⅲ non-squamous NSCLC were randomized to UFT 400 mg/m2 on days 1–14 and 29–42, and cisplatin 80 mg/m2 on days 8 and 36 (UP), or pemetrexed 500 mg/m2 and cisplatin 75 mg/m2 on days 1, 22, and 43 (PP). Involved-field radiotherapy (IFRT) was administered from day 1 to a total dose of 66 Gy radiotherapy in 33 fractions. Consolidation chemotherapy after CCRT was not planned for this study. The primary endpoint was 2-year overall survival (OS), with expected rates of 55% and a lower limit of 35% (alfa 0.05, beta 0.2). Secondary endpoints were the objective response rate (ORR), progression-free survival (PFS), OS, and toxicity profile. Results: From November 2010 to June 2017, 86 patients were enrolled from 11 institutions. Of the 85 eligible patients, the rate of 2-year OS was 78.6% (95% CI: 62.8–88.3%) in the UP arm and 85.5% (95% CI: 70.5–93.2%) in the PP arm. The ORR was 76.7% in the UP arm and 81.0% in the PP arm. With a median follow-up of 54 months, median PFS and OS were 12.3 and 64.2 months in the UP arm, and 26.2 months and not reached in the PP arm, respectively. Grade 3/4 febrile neutropenia was more frequent in the UP arm than in the PP arm (14.0%, 2.0%, respectively). Grade 3/4 pneumonitis occurred in 7.0% and 4.8% of patients in UP and PP arms, respectively. Conclusions: Both regimens with IFRT achieved the expected 2-year survival rate. PP had more favorable results than UP in terms of OS and PFS. We selected the PP arm for the next step.

301 Background: In the phase III JAVELIN Renal 101 trial (NCT02684006), A + Ax demonstrated significantly longer progression-free survival (PFS) and a higher objective response rate (ORR) vs S in patients with previously untreated aRCC. The role of immune checkpoint + VEGFR inhibition in elderly patients remains unclear. Here we report the efficacy of A + Ax vs S by age group from the second interim analysis (IA) of overall survival (OS) and the safety of A + Ax by age group from the first IA. Methods: Patients were randomized 1:1 to receive A 10 mg/kg intravenously every 2 wk + Ax 5 mg orally twice daily or S 50 mg orally once daily for 4 wk (6-wk cycle). PFS and ORR per independent central review (RECIST 1.1), OS, and safety by age group (<65, ≥65 to <75, and ≥75 y) were assessed. Results: A total of 271/138/33 and 275/128/41 patients in each age group (<65, ≥65 to <75, and ≥75 y, respectively) were randomized to the A + Ax or S arm, respectively. The proportion of IMDC risk groups was generally well balanced between the A + Ax and S arm in each age group, although in the ≥75 y age group, the frequency of patients with intermediate risk was slightly higher in the A + Ax arm, and that of patients with favorable risk was slightly higher in the S arm. The percentages of patients with favorable/intermediate/poor risk in each age group were 19%/61%/19%, 28%/58%/13%, and 12%/76%/12% in the A + Ax arm vs 20%/63%/16%, 23%/60%/16%, and 24%/61%/15% in the S arm. At data cut-off (Jan 2019) for the second IA, median follow-up for OS and PFS was 19.3 vs 19.2 mo and 16.8 vs 15.2 mo for the A + Ax vs S arm, respectively. The table shows OS, PFS, and ORR by age group. In the A + Ax arm, the most common treatment-emergent adverse events (AEs) were diarrhea (62%/68%/42%), hypertension (49%/49%/55%), palmar-plantar erythrodysesthesia syndrome (37%/31%/15%), fatigue (37%/53%/30%), and nausea (34%/37%/21%) in each age group. Grade ≥3 treatment-emergent AEs and immune-related AEs were observed in 69%/74%/73% and 39%/40%/24% of patients in each age group, respectively. Conclusions: A + Ax demonstrated favorable efficacy across age groups, including patients aged ≥75 y. OS was still immature; follow-up for the final analysis is ongoing. The safety profile was generally consistent between age groups. Clinical trial information: NCT02684006 . [Table: see text]

PURPOSE Nivolumab 1 mg/kg plus ipilimumab 3 mg/kg (NIVO1+IPI3) is approved for first-line treatment of patients with advanced melanoma in several countries. We conducted a phase IIIb/IV study (CheckMate 511) to determine if nivolumab 3 mg/kg plus ipilimumab 1 mg/kg (NIVO3+IPI1) improves the safety profile of the combination. PATIENTS AND METHODS Patients (N = 360) age 18 years or older with previously untreated, unresectable stage III or IV melanoma were randomly assigned 1:1 to NIVO3+IPI1 or NIVO1+IPI3 once every 3 weeks for four doses. After 6 weeks, all patients received NIVO 480 mg once every 4 weeks until disease progression or unacceptable toxicity. The primary end point was a comparison of the incidence of treatment-related grade 3 to 5 adverse events (AEs) between groups. Secondary end points included descriptive analyses of objective response rate, progression-free survival, and overall survival. The study was not designed to formally demonstrate noninferiority of NIVO3+IPI1 to NIVO1+IPI3 for efficacy end points. RESULTS At a minimum follow-up of 12 months, incidence of treatment-related grade 3 to 5 AEs was 34% with NIVO3+IPI1 versus 48% with NIVO1+IPI3 ( P = .006). In descriptive analyses, objective response rate was 45.6% in the NIVO3+IPI1 group and 50.6% in the NIVO1+IPI3 group, with complete responses in 15.0% and 13.5% of patients, respectively. Median progression-free survival was 9.9 months in the NIVO3+IPI1 group and 8.9 months in the NIVO1+IPI3 group. Median overall survival was not reached in either group. CONCLUSION The CheckMate 511 study met its primary end point, demonstrating a significantly lower incidence of treatment-related grade 3-5 AEs with NIVO3+IPI1 versus NIVO1+IPI3. Descriptive analyses showed that there were no meaningful differences between the groups for any efficacy end point, although longer follow up may help to better characterize efficacy outcomes.

Abstract Purpose: Hypofractionated radiotherapy (HypoRT) shows the superiority in cancer treatment because of its high biological equivalent dose. This retrospective study aims to evaluate the toxicity and efficacy of HypoRT on small cell lung cancer (SCLC).Methods: Medical records of SCLC patients between July 2018 and October 2019 were collected. All patients treated with chemotherapy plus HypoRT (PTV: 30 Gy/10F, PGTV: 45 Gy/10F) were eligible for analysis. The chemotherapy was performed for a total of 4-6 cycles by using Etoposide plus Cisplatin or Carboplatin in peri-radiotherapy phase. Meanwhile, indexes including in-field recurrence rate (ifRR), in-field relapse-free survival (ifRFS) and overall survival (OS) were calculated. Results: Medical data of 30 patients were eligible for analysis. Male to female ratio was 19: 11. The median age was 64 (range from 46 to 75 years old, 95% CI: 52.5-83.75). The median follow-up time was 15 months (range from 1 to 19 months). In follow-up period, either radiation esophagitis or radiation pneumonitis of grade 3 occurred in 6.7% of the patients (2/30). The incidences of severe hematologic toxicities (grade 3/4) including leukopenia, granulocytopenia, thrombocytopenia and anemia were 33.3%, 66.7%, 26.7% and 16.7%, respectively. The ifRR post-HypoRT was 6.7% (2/30) with a median ifRFS of 15 months (rang from 1 to 19 months, 95% CI: 11.25-18.75) and a median OS of 15 months (range from 1 to 19, 95% CI: 11.25-18.75).Conclusion: HypoRT can be tolerated by most of enrolled patients, and HypoRT exhibits its efficacy in controlling SCLC tumors.

BackgroundPrevious studies have explored cancer immunotherapy with radiotherapy or anti-angiogenic therapy, but no trials have reported a triple therapy approach. This study aimed to investigate safety and clinical outcome of PD-1/PD-L1 inhibitors combined with palliative radiotherapy and targeted angiogenesis therapy in hepatocellular carcinoma (HCC) of Barcelona Clinic Liver Cancer (BCLC) stage C.MethodsConsecutive patients (n=16) treated with PD-1/PD-L1 inhibitors combined with radiotherapy and anti-angiogenic therapy in a bi-institutional cohort between July 2017 and December 2020 were retrospectively included. Radiotherapy was conducted within 14 days of the first administration of immunotherapy. The primary endpoint was treatment-related adverse event (TRAE).ResultsThe median follow-up was 383 days. Fifteen patients (93.8%) experienced at least 1 TRAE. The most common TRAEs of any grade were rash (25%), diarrhea (25%), aspartate aminotransferase increase (18.8%), alanine transaminase increase (18.8%), decreased appetite (18.8%), and fatigue (18.8%). Grade 3/4 TRAEs occurred in 4 patients (25%) and finally led to treatment interruption. No patient death was attributed to treatment. No specific events were responsible for the addition of radiotherapy. Six patients showed partial response, 7 showed stable disease, and 2 showed progressive disease. The objective response rate and disease control rate were 40.0% (95% CI 16.3%–67.7%) and 86.7% (95% CI 59.5%–98.3%), respectively. Moreover, the median progression-free survival was 140 days. Patients had a median overall survival of 637 days, and the estimated rates of survival at 6 and 12 months were 92.3% and 75.5%, respectively.ConclusionPD-1/PD-L1 inhibitors combined with palliative radiotherapy and anti-angiogenic therapy appear to be safe, with no unexpected adverse events. Additional studies exploring the clinical benefit are warranted.
