Purpose: Cisplatin-containing combination chemotherapy has been the standard of care since the late 1980s, but the response rate is <50%. Studies have shown that the efficiency of chemotherapy differs among molecular subtypes of bladder cancer. In this study, we aimed to correlate FOXA1, a marker for differentiation of the basal and luminal subtypes, with tumor immune cell infiltration and the effect of chemotherapy in bladder cancer. Materials and Methods: Eighty-three patients with bladder cancer treated with chemotherapy were reviewed. Clinicopathological variables for each case were recorded. FOXA1, M2 tumor-associated macrophage (TAM), dendritic cell (DC), and cytotoxic T lymphocyte (CTL) were examined by immunohistochemistry. The relationship between FOXA1, immune cell infiltration, and clinical response to chemotherapy was assessed. Results: The overall objective response rate was 34%. The objective response rate for tumors with lower FOXA1 expression was 58% and for tumors with higher FOXA1 expression was 12%. Tumors with infiltrated M2 TAM proportion <3% had a higher objective response rate compared with infiltrated M2 TAM proportion >3% tumors (46% vs. 21%, p = 0.02). Tumors with infiltrated CTL proportion >5% had a higher objective response rate compared with infiltrated CTL proportion <5% tumors (50% vs. 17%, p = 0.002). DCs showed no significant differences. We found that the objective response rate for tumors with lower FOXA1 expression, proportion <3% M2 TAM infiltration, and proportion >5% CTL infiltration is 82%. Lower FOXA1 expression was associated with low M2 TAM infiltration and high CTL infiltration. Conclusions: Thus, we showed that in patients with bladder cancer who received chemotherapy, the higher clinical response rate is associated with low FOXA1 expression, low M2 TAM infiltration, and high CTL infiltration.

Purpose Previously, we reported our experience treating 14 patients with metastatic melanoma using a fully human antibody to cytotoxic T-lymphocyte antigen-4 (anti–CTLA-4) in conjunction with peptide vaccination. We have now treated 56 patients to evaluate two different dose schedules of anti–CTLA-4 and to explore the relationship between autoimmunity and tumor regression. Patients and Methods A total of 56 patients with progressive stage IV melanoma were enrolled onto the study. All had Karnofsky performance status ≥ 60% with no prior history of autoimmunity. Twenty-nine patients received 3 mg/kg anti–CTLA-4 every 3 weeks, whereas 27 received 3 mg/kg as their initial dose with subsequent doses reduced to 1 mg/kg every 3 weeks. In both cohorts patients received concomitant vaccination with two modified HLA-A*0201-restricted peptides from the gp100 melanoma-associated antigen, gp100:209-217(210M) and gp100:280-288(288V). Results Two patients achieved a complete response (ongoing at 30 and 31 months, respectively) and five patients achieved a partial response (durations of 4, 6, 25+, 26+, and 34+ months, respectively), for an overall objective response rate of 13%. Tumor regression was seen in lung, liver, brain, lymph nodes, and subcutaneous sites. Of 14 patients with grade 3/4 autoimmune toxicity, five (36%) experienced a clinical response compared with only two responses in the 42 patients (5%) with no autoimmune toxicity (P = .008). There were no significant differences in response rate or toxicity between the two dose schedules. Conclusion Administration of anti–CTLA-4 monoclonal antibody plus peptide vaccination can cause durable objective responses, which correlate with the induction of autoimmunity, in patients with metastatic melanoma.

Purpose Combining immunotherapeutic agents with different mechanisms of action may enhance efficacy. We describe the safety and efficacy of talimogene laherparepvec (T-VEC; an oncolytic virus) in combination with ipilimumab (a cytotoxic T-lymphocyte–associated antigen 4 checkpoint inhibitor) in patients with advanced melanoma. Methods In this open-label, multicenter, phase Ib trial of T-VEC in combination with ipilimumab, T-VEC was administered intratumorally in week 1 (106 plaque-forming units/mL), then in week 4 and every 2 weeks thereafter (108 plaque-forming units/mL). Ipilimumab (3 mg/kg) was administered intravenously every 3 weeks for four infusions, beginning in week 6. The primary end point was incidence of dose-limiting toxicities. Secondary end points were objective response rate by immune-related response criteria and safety. Results Median duration of treatment with T-VEC was 13.3 weeks (range, 2.0 to 95.4 weeks). Median follow-up time for survival analysis was 20.0 months (1.0 to 25.4 months). Nineteen patients were included in the safety analysis. No dose-limiting toxicities occurred, and no new safety signals were detected. Grade 3/4 treatment-related adverse events (AEs) were seen in 26.3% of patients; 15.8% had AEs attributed to T-VEC, and 21.1% had AEs attributed to ipilimumab. The objective response rate was 50%, and 44% of patients had a durable response lasting ≥ 6 months. Eighteen-month progression-free survival was 50%; 18-month overall survival was 67%. Conclusion T-VEC with ipilimumab had a tolerable safety profile, and the combination appeared to have greater efficacy than either T-VEC or ipilimumab monotherapy.

Introduction: Crizotinib was approved to treat anaplastic lymphoma kinase (ALK)- positive non-small cell lung cancer (NSCLC) by the Food and Drug Administration in 2011.We conducted a systematic review of clinical trials and retrospective studies to compare the efficacy and safety of crizotinib with chemotherapy. </P><P> Methods: We searched electronic databases from inception to Dec. 2016. Clinical trials and retrospective studies regarding crizotinib and crizotinib versus chemotherapy in treatment of NSCLC were eligible. The primary outcomes were the objective response rate (ORR) and disease control rate (DCR). Results: Nine studies (five clinical trials and four retrospective studies) including 729 patients met the inclusion criteria. Crizotinib treatment revealed 1-year OS of 77.1% and PFS of 9.17 months. And crizotinib had a better performance than chemotherapy in ORR (OR: 4.97, 95%CI: 3.16 to 7.83, P<0.00001, I2=35%). DCR revealed superiority with crizotinib than chemotherapy (OR: 3.42, 95% CI: 2.33 to 5.01, P<0.00001, I2=0%). PR (partial response) were significant superior to that of chemotherapy through direct systematic review. No statistically significant difference in CR (complete response) was found between crizotinib-treated group and chemotherapy-treated group. Regarding SD (stable disease), chemotherapy-treated group had a better performance than crizotinib-treated group. Common adverse events associated with crizotinib were visual disorder, gastrointestinal side effects, and elevated liver aminotransferase levels, whereas common adverse events with chemotherapy were fatigue, nausea, and hematologic toxicity. This systematic review revealed improved objective response rate and increased disease control rate in crizotinib group comparing with chemotherapy group. Crizotinib treatment would be a favorable treatment option for patients with ALK-positive NSCLC. ALK inhibitors may have future potential applications in other cancers driven by ALK or c-MET gene mutations.

BackgroundTargeting transforming growth factor-β (TGF-β) is reported to augment the efficacy of immune checkpoint inhibitors (ICIs) through either enhanced anti-tumor immunity or the correction of tumor microenvironment (TME). Therefore, the combination of vactosertib, a highly selective TGF-β RI kinase inhibitor, and durvalumab is anticipated to improve anti-tumor activity of the ICI. A phase 1b/2a study was conducted to evaluate the combination of vactosertib and durvalumab in patients with advanced NSCLC who progressed after platinum-based chemotherapy.MethodsPatients were treated with vactosertib at a dose of 200 mg twice daily (five days on and two days off) and durvalumab at a dose of 1500 mg every four weeks. Eligible patients were ≥19 years old with good performance status (ECOG 0–1) and have no prior exposure to immune checkpoint inhibitors or other TGF- β R1 kinase inhibitors. The objectives of this analysis were to evaluate the safety, antitumor activity including objective response rate (ORR), duration of response (DOR), and time to response (TTR) as well as circulating pharmacodynamic biomarkers related to TGF-β signaling. Response was assessed per RECIST (v1.1).ResultsBy August 4 2020, twenty-six PD-L1 positive (SP263 assay) patients were analyzed. Median age was 61.5 years (range 48–83), 69.2% were male, median number of previous lines of chemotherapy was 1 (range 1–4), and all patients were PD-L1 positive (15 patients with PD-L1≥25% and 11 patients with PD-L1 1–24%). The most frequently reported treatment-related adverse events (TRAE) were itching (38.5%) and skin rash (34.6%), but no Gr≥3 itching and rash were observed. Each case of the following was reported as Grade 3 TRAEs: adrenal insufficiency, anemia, and pneumonitis; Grade 4 TRAE, CPK increase, was observed in one patient. Objective response rate was 30.8% and 40.0% in patients with PD-L1≥1% and ≥25% respectively. Circulating PAI-1 and CTGF evaluated in 15 patients decreased significantly on Cycle 1 day 5. Ongoing biomarker results will be presented.ConclusionsThe combination of vactosertib and durvalumab has demonstrated a manageable safety profile and encouraging anti-tumor activity as a potential therapeutic strategy in patients with advanced NSCLC. The efficacy outcomes of this combination in a larger number of patients with advanced NSCLC will be followed.Trial RegistrationNCT03732274Ethics ApprovalThe study was approved by Ethics Board of Severance Hospital (4-2018-0892), National Cancer Center (NCC2019-0057), St. Vincent’s Hospital (VC19MDDF0205), and Chungbuk National University Hospital (2019-08-015).

Purpose Patients with advanced non‒small-cell lung cancer (NSCLC) who fail two lines of chemotherapy have unmet medical needs. The kinase inhibitor fruquintinib selectively targets vascular endothelial growth factor receptors and, hence, tumor angiogenesis and lymphogenesis. This randomized, double-blind, placebo-controlled, multicenter phase II trial evaluated the efficacy and safety of fruquintinib in patients with advanced nonsquamous NSCLC who experienced disease progression after second-line chemotherapy. Patients and Methods Eligible patients were randomly assigned (two to one; stratified by epidermal growth factor receptor status) to receive fruquintinib or placebo, both in combination with best supportive care. Oral fruquintinib (5 mg once daily) was given in 4-week cycles of 3 weeks of treatment followed by 1 week off. Tumor response was assessed using Response Evaluation Criteria in Solid Tumors version 1.1. The primary end point was progression-free survival (PFS) evaluated by a blinded image central review (BICR) committee. Secondary end points included investigator-evaluated PFS, objective response rate, disease control rate, overall survival, and safety. Results Ninety-one patients from 12 hospitals received treatment with fruquintinib (n = 61) or placebo (n = 30). Median PFS was 3.8 months with fruquintinib by both BICR and investigators’ evaluations (hazard ratio by BICR, 0.34; 95% CI, 0.20 to 0.57; P < .001). Three- and 6-month survival rates were 90.2% and 67.2% in the fruquintinib group and 73.3% and 58.8% in the placebo group, respectively. The objective response rate and disease control rate were 13.1% and 60.7% with fruquintinib, compared with 0% and 13.3% with placebo ( P = .041 and < .001), respectively. The most common treatment-emergent adverse events with fruquintinib (≥ grade 3) were hypertension (8.2%), hand-foot syndrome (4.9%), and proteinuria (4.9%). Conclusion Third- and fourth-line fruquintinib for advanced NSCLC was superior to placebo and had an acceptable safety profile.

Purpose Atypical teratoid rhabdoid tumor (ATRT) of the CNS is a highly malignant neoplasm primarily affecting young children, with a historic median survival ranging from 6 to 11 months. Based on a previous pilot series, a prospective multi-institutional trial was conducted for patients with newly diagnosed CNS ATRT. Patients and Methods Treatment was divided into five phases: preirradiation, chemoradiation, consolidation, maintenance, and continuation therapy. Intrathecal chemotherapy was administered, alternating intralumbar and intraventricular routes. Radiation therapy (RT) was prescribed, either focal (54 Gy) or craniospinal (36 Gy, plus primary boost), depending on age and extent of disease at diagnosis. Results Between 2004 and 2006, 25 patients were enrolled; 20 were eligible for evaluation. Median age at diagnosis was 26 months (range, 2.4 months to 19.5 years). Gross total resection of the primary tumor was achieved in 11 patients. Fourteen patients had M0 disease at diagnosis, one patient had M2 disease, and five patients had M3 disease. Fifteen patients received radiation therapy: 11 focal and four craniospinal. Significant toxicities, in addition to the expected, included radiation recall (n = 2) and transverse myelitis (n = 1). There was one toxic death. Of the 12 patients who were assessable for chemotherapeutic response (pre-RT), the objective response rate was 58%. The objective response rate observed after RT was 38%. The 2-year progression-free and overall survival rates are 53% ± 13% and 70% ± 10%, respectively. Median overall survival has not yet been reached. Conclusion This intensive multimodality regimen has resulted in a significant improvement in time to progression and overall survival for patients with this previously poor-prognosis tumor.

The article presents the experience of 19 Russian medical institutions on the use of eribulin in combination with trastuzumab in various treatment lines of metastatic HER2+ breast cancer in routine clinical practice. Aim. The main objective of this retrospective observational study was to evaluate the efficacy and tolerability of eribulin and trastuzumab combo in HER2+ breast cancer patients pretreated with anthracyclines and taxanes. The analysis included 60 patients who received at least 2 cycles of eribulin in combination with trastuzumab. 2 patients (3.3%) received treatment as the 1st line, as the 2nd 14 (23.3%), as the 3rd 16 (26.7%), and as the 4th and more 28 (46.7%). Materials and methods. Complete response was achieved in 2 (3.3%) patients, partial response in 9 (15%), stable disease in 33 (55%), stabilization for more than 6 months in 11 (18.3%), disease progression was detected in 16 (26.7%) patients. The objective response rate was 18.3% in the whole group, the clinical benefit rate 36.7%. Results. The objective response rate in the group of the luminal subtype (ER/PR+HER2+) was 26.9%, in HER2-overexpressed subtype (ER-PR-HER2+) 8.8% and 64.7%, respectively, disease progression was recorded 2.3 times more often 35.3% versus 15.5% in the luminal subtype group. The median progression-free survival in patients with HER2+ breast cancer was 4.95 months (95% confidence interval CI 3.048.29 months), in luminal subtype 6.38 months (95% CI 3.338.54 months), in non-luminal 4.44 months (95% CI 2.47.96 months); p=0.306. The treatment was well tolerated, the spectrum of adverse events corresponded to the eribulin toxicity profile. Conclusions. The uniqueness of this study lies in the fact that on a large clinical material from the standpoint of real clinical practice, a very promising treatment regimen that is not used routinely in a number of countries has been studied, its effectiveness and satisfactory tolerance have been confirmed.

Introduction Almost half of patients with non-small-cell lung cancer (NSCLC) are diagnosed at an advanced stage. Our aim was to assess the effects of adding necitumumab to chemotherapy in patients with stage IV NSCLC. Material and methods A comprehensive literature search was performed according to pre-specified inclusion and exclusion criteria. Data on overall survival, progression-free survival, objective response rate and adverse events were extracted. A meta-analysis was performed to obtain pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI) for time-to-event data and pooled odds ratio (OR) with 95% CI for dichotomous outcomes. Results The meta-analysis included four randomized clinical trials with 2074 patients. The pooled results showed significant improvement for overall survival (HR = 0.87 (95% CI 0.79–0.95), p = 0.004) when necitumumab was added to chemotherapy in patients with advanced NSCLC. No statistically significant improvement was noted for progression-free survival and objective response rate (HR = 0.83 (95% CI 0.69–1.01), p = 0.06 and OR = 1.46 (95% CI 0.90–2.38), p = 0.13, respectively). Subgroup analysis showed that in patients with non-squamous NSCLC, there was no benefit in overall survival and objective response rate. Patients with advanced NSCLC who received necitumumab were at the highest odds of developing a skin rash (OR = 14.50 (95% CI 3.16–66.43), p = 0.0006) and hypomagnesaemia (OR = 2.77 (95% CI 2.23–3.45), p < 0.00001), while the OR for any grade ≥3 adverse event was 1.55 (95% CI 1.28–1.87, p < 0.00001). Conclusions The addition of necitumumab to standard chemotherapy in a first-line setting in patients with stage IV NSCLC results in a statistically significant improvement in overall survival, while the results were not significant for progression-free survival and objective response rate.

PURPOSE Targeted therapies against non–small-cell lung cancer (NSCLC) harboring HER2 mutations remain an unmet need. In this study, we assessed the efficacy and safety of pyrotinib in patients with HER2-mutant advanced NSCLC in a prospective, multicenter, open-label, single-arm, phase II study. PATIENTS AND METHODS Patients with stage IIIB or IV HER2-mutant lung adenocarcinoma who were previously treated with platinum-based chemotherapy were enrolled to receive pyrotinib at a dose of 400 mg/d for 21-day cycles. The primary end point was objective response rate per independent review committee (IRC). RESULTS Between October 20, 2016, and December 10, 2018, 60 patients received pyrotinib monotherapy. At baseline, 58 (96.7%) were stage IV, and 25 (41.7%) received at least 2 lines of prior chemotherapy. As of data cutoff on June 20, 2019, IRC-assessed objective response rate was 30.0% (95% CI, 18.8% to 43.2%). All subgroups of patients with different HER2 mutation types showed a favorable objective response rate. The objective response rates were similar between patients with and without brain metastases (25.0% v 31.3%). The median duration of response was 6.9 months (95% CI, 4.9 to 11.1 months). The median progression-free survival was 6.9 months (95% CI, 5.5 to 8.3 months) per IRC. The median overall survival was 14.4 months (95% CI, 12.3 to 21.3 months). Treatment-related adverse events of grade 3 or 4 occurred in 28.3% of patients, with the most common being diarrhea (20.0%; all grade 3). No treatment-related deaths were reported. CONCLUSION Pyrotinib showed promising antitumor activity and an acceptable safety profile in chemotherapy-treated patients with HER2-mutant NSCLC.
