Abstract
BACKGROUND To report our findings on quality of life (QoL) in a randomized phase II study to determine the optimal dose of 3-week cycle nab-paclitaxel (q3w nab-PTX) in patients with metastatic breast cancer (MBC). METHODS Patients with HER2-negative MBC were randomly assigned to three different doses of q3w nab-PTX (SD 260 mg/m2 vs. MD: 220 mg/m2 vs. LD 180 mg/m2). QoL was assessed at baseline and during the second, fourth and sixth courses of treatment using the Functional Assessment of Cancer Therapy-Taxane (FACT-Taxane), Cancer Fatigue Scale (CFS) and EuroQol 5-Dimension (EQ-5D). Comparisons were performed with mixed-model repeated measures (MMRM). RESULTS A total of 141 patients were enrolled in the parent study, and 136 (96%) (44, 45 and 47 in the SD, MD, and LD groups) were included in the analysis. MMRM analysis showed that the difference from the baseline FACT-Taxane trial outcome index at MD and LD were significantly higher than that at SD (MD vs. SD P < 0.001, LD vs. SD P < 0.001). Differences from baseline for FACT-Taxane total, physical and emotional well-being, and taxane subscale scores at MD and LD were also higher than at SD. The difference from baseline for the CFS score at LD was lower than at SD (P = 0.013) and those for EQ-5D utility scores at MD and LD were higher than at SD (MD vs. SD P = 0.011, LD vs. SD P < 0.001). CONCLUSION QoL of patients treated with 220 or 180 mg/m2 of q3w nab-PTX was significantly better than that of patients treated with 260 mg/m2. TRIAL REGISTRATION The protocol was registered at the website of the University Hospital Medical Information Network (UMIN), Japan (protocol ID: UMIN000015516), on 01/11/2014.

Abstract
BACKGROUND This study evaluated the association between early tumor response at 8 weeks, previously reported as a positive outcome prognosticator, and health-related quality of life (HRQOL) in advanced gastric cancer (AGC) patients enrolled in the ABSOLUTE trial. METHODS HRQOL was assessed using the EuroQol-5 Dimension (EQ-5D) utility index score in patients with complete response (CR) + partial response (PR) and progressive disease (PD) at 8 weeks, and time-to-deterioration (TtD) of the EQ-5D score, with the preset minimally important difference (MID) of 0.05, was compared between these populations. Among the enrolled patients, 143 and 160 patients were assessable in weekly solvent-based paclitaxel (Sb-PTX) arm and weekly nanoparticle albumin-bound paclitaxel (nab-PTX) arm, respectively. RESULTS Changes of the EQ-5D score from baseline to 8 weeks in the nab-PTX arm were 0.0009 and - 0.1229 in CR + PR and PD patients, respectively; the corresponding values for the Sb-PTX arm were - 0.0019 and - 0.1549. For both treatments, changes of the EQ-5D score from baseline at 8 weeks were significantly larger in patients with PD than in those with CR + PR. The median TtD was 3.9 and 2.2 months in patients with CR + PR and PD, respectively, for nab-PTX [hazard ratio (HR) = 0.595, 95% confidence interval (CI) 0.358-0.989]. For Sb-PTX, the corresponding values were 4.7 and 2.0 months (HR = 0.494, 95% CI 0.291-0.841). CONCLUSIONS Early tumor shrinkage was associated with maintained HRQOL in AGC patients on the second-line chemotherapy with taxanes.

Abstract
BACKGROUND Pancreatic cancer is associated with low median overall survival. Combination chemotherapy regimens FOLFIRINOX and gemcitabine with nab-paclitaxel (GemNab) are the new adjuvant treatment standards for resectable pancreatic cancer. PRODIGE-24 and APACT trials demonstrated superior clinical outcomes with FOLFIRINOX and GemNab, each vs gemcitabine monotherapy. OBJECTIVE To evaluate the cost-effectiveness of FOLFIRINOX vs GemNab for resectable pancreatic cancer in adults from the U.S. payer perspective, in order to inform decision makers about which of these treatments is optimal. METHODS A Markov model with 3 disease states (relapse free, progressive disease, and death) was developed. Cycle length was 1 month, and time horizon was 10 years. Transition probabilities were derived from PRODIGE-24 and APACT survival data. All cost and utility input parameters were obtained from published literature. Cost-effectiveness analysis was performed to obtain total costs, quality-adjusted life-years (QALYs), life-years (LYs), and incremental cost-effectiveness ratio (ICER). A 3% annual discount rate was applied to costs and outcomes. The effect of uncertainty on model parameters was assessed with 1-way and probabilistic sensitivity analysis (PSA). RESULTS Our analysis estimated that the cost for FOLFIRINOX was $40,831 higher than GemNab ($99,669 vs. $58,837). Despite increased toxicity, FOLFIRINOX was associated with additional 0.18 QALYs and 0.25 LYs compared with GemNab (QALY: 1.65 vs. 1.47; LY: 2.09 vs. 1.84). The ICER for FOLFIRINOX vs GemNab was $226,841 per QALY and $163,325 per LY. FOLFIRINOX was not cost-effective at a willingness-to-pay (WTP) threshold of $200,000 per QALY, and this was confirmed by the PSA. CONCLUSIONS Total monthly cost for FOLFIRINOX was approximately 1.7 times higher than GemNab. If the WTP threshold increases to or above $250,000 per QALY, FOLFIRINOX then becomes a cost-effective treatment option.

Abstract
PURPOSE Ceralasertib is a potent and selective oral inhibitor of the serine/threonine protein kinase ataxia telangiectasia and Rad3-related (ATR) protein. PATIENTS AND METHODS Eligible patients with solid tumors, enriched for melanoma, received ceralasertib in combination with a fixed dose of paclitaxel (80 mg/m2 on D1, D8, D15) in 28-day cycles. The dose of ceralasertib was escalated to reach an MTD in a rolling 6 design. The starting dose of ceralasertib was 40 mg QD. Fifty-seven patients (33 patients with melanoma who failed prior PD1/L1 treatment) were enrolled in 7 dose cohorts ranging from 40 mg QD to 240 mg BD plus weekly paclitaxel. RESULTS The RP2D was established as ceralasertib 240 mg BD days 1-14 plus paclitaxel 80 mg/m2 on D1, D8, D15 every 28 days. The most common toxicities were neutropenia (n = 39, 68%), anemia (n = 25, 44%), and thrombocytopenia (n = 21, 37%). In the full analysis set of 57 patients, the overall response rate (ORR) was 22.6% (95% CI, 12.5-35.3). In 33 patients with melanoma, resistant to prior anti-PD1 therapy, the ORR was 33.3% (95% CI, 18.0-51.8). In the melanoma subset, the mPFS was 3.6 months (95% CI, 2.0-5.8), the median duration of response was 9.9 months (95% CI, 3.7-23.2), and the mOS was 7.4 months (95% CI, 5.7-11.9). CONCLUSIONS Ceralasertib in combination with paclitaxel was well tolerated in patients with advanced malignancies and showed evidence of antitumor activity. Durable responses were observed in patients with advanced cutaneous, acral, and mucosal melanoma resistant to anti-PD1/L1 treatment.See related commentary by Ashworth, p. 4667.

Abstract
Aim: This study explored whether inherited variants in genes causing the hereditary neuropathy condition Charcot-Marie-Tooth disease are associated with sensitivity to paclitaxel-induced peripheral neuropathy (PN). Patients & methods: Hereditary neuropathy genes previously associated with risk of paclitaxel-induced PN were sequenced in paclitaxel-treated patients. Eight putative genetic predictors in five hereditary neuropathy genes (ARHGEF10, SBF2, FGD4, FZD3 and NXN) were tested for association with PN sensitivity after accounting for systemic exposure and clinical variables. Results:FZD3 rs7833751, a proxy for rs7001034, decreased PN sensitivity (additive model, β = -0.41; 95% CI: -0.66 to -0.17; p = 0.0011). None of the other genetic predictors were associated with PN sensitivity. Conclusion: Our results support prior evidence that FZD3 rs7001034 is protective of PN and may be useful for individualizing paclitaxel treatment to prevent PN.

Abstract
OBJECTIVE The optimal neoadjuvant therapy for resectable pancreatic ductal adenocarcinoma (PDA) and the impact on surgical outcomes remains unclear. METHODS S1505 (NCT02562716) was a randomized phase II study of perioperative chemotherapy with mFOLFIRINOX (Arm 1) or gemcitabine/nab-paclitaxel (Arm 2). Measured parameters included resection rate, margin positivity, pathologic response, and toxicity. RESULTS Between 2015 and 2018, 147 patients were randomized. Of these, 44 (30%) were deemed ineligible (43 by central review). Of the 103 eligible patients, 77 (76%) completed preoperative therapy and underwent surgery; reasons patients did not undergo surgery included toxicity related to preoperative therapy (n = 9), progression (n = 9), or other (n = 7). Of the 77, 73 (95%) underwent successful resection; 21 (29%) required vascular reconstruction, 62 (85%) had negative (R0) margins, and 24 (33%) had a complete or major pathologic response to therapy. The grade 3-5 postoperative complication rate was 16%. Of the 73 patients completing surgery, 57 (78%) started and 46 (63%) completed postoperative therapy. This study represents the first prospective trial evaluating modern systemic therapy delivered in a neoadjuvant/perioperative format for resectable PDA. CONCLUSIONS We have demonstrated: (1) Based on the high percentage of enrolled, but ineligible patients, it is clear that adherence to strict definitions of resectable PDA is challenging; (2) Patients can tolerate modern systemic therapy and undergo successful surgical resection without prohibitive perioperative complications; (3) Completion of adjuvant therapy in the perioperative format is difficult; (4) Major pathologic response rate of 33% is encouraging.

Abstract
BACKGROUND Prolonged dual-antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients undergoing percutaneous coronary intervention can be challenging. We assessed the clinical safety of bare-metal stent (BMS) implantation followed by drug-coated balloon (DCB) treatment in HBR patients for whom drug-eluting stent implantation could be problematic in maintaining low ischemic event rate without increasing hemorrhagic events. METHODS The study included patients with at least 1 de novo lesion who were either under long-term anticoagulant treatment or required semi-urgent non-coronary intervention. The strategy consisted of PRO-Kinetic Energy BMS stent (Biotronik AG) implantation followed by Pantera Lux DCB (Biotronik AG) and patients were followed for up to 12 months in 37 French centers. RESULTS Between October 2013 and April 2015, a total of 432 patients with 623 de novo lesions who were either under long-term anticoagulant treatment (n = 300) or required semi-urgent non-cardiac surgery (n = 132) were treated by BMS plus DCB. Mean patient age was 74.1 ± 9.1 years, 76.4% were men, and 38% were diabetic. The composite primary endpoint rate (defined as target-lesion failure at 12 months) was 5.6% (95% confidence interval, 3.3-7.9). Median duration for DAPT treatment was 33 days. Hemorrhagic events, as defined by the Bleeding Academic Research Consortium, occurred in 31 patients (7.2%) and definite stent thrombosis occurred in 5 patients (1.3%). CONCLUSIONS The combination of BMS plus DCB intervention is safe even with a short duration of DAPT. This strategy might be an alternative to DES implantation in HBR patients if future randomized trials support this approach.

Abstract
BACKGROUND Malignant airway obstruction (MAO) occurs in 30% of patients with advanced-stage lung cancer, leading to debilitating dyspnea, cough, and hemoptysis. Other than recanalization of the airways, these patients lack long-lasting palliative therapy. The goal of this study was to determine the safety and feasibility of local injection of paclitaxel into the airway wall with a novel microinjection catheter. METHODS In this multicentered prospective trial, 23 patients with non-small cell lung cancer and MAO were enrolled from July 2014 through June 2016 to undergo rigid bronchoscopy with recanalization, followed by injection of 1.5 mg of paclitaxel with a novel injection catheter. Primary end points consisted of safety (adverse events, severe adverse events, and unanticipated adverse device effects) as well as feasibility (number of injections, injection success). Secondary end points consisted of airway patency improvement, quality of life metrics, and need for further interventions and/or stenting. RESULTS Nineteen patients underwent rigid bronchoscopy with successful recanalization and paclitaxel injection. There were no adverse events, severe adverse events, or unanticipated adverse device effects. There was an average of 3.4 injections given for a total dose of 1.5 mg of paclitaxel in all patients. There was significantly less stenosis postprocedure vs preprocedure (25%-50% vs 75%-90%; P < .001), which was unchanged at 6 weeks (25%-50%). None of the participants required further interventions or airway stenting. CONCLUSIONS The injection of paclitaxel after recanalization of MAO in patients with non-small cell lung cancer is safe and feasible, using a novel airway injection device.

Abstract
IMPORTANCE Ramucirumab, a human IgG 1 antibody against vascular endothelial growth factor receptor 2, has been shown to improve progression-free survival and overall survival in patients with advanced gastric cancer in the second-line setting. OBJECTIVE To compare progression-free survival for S-1 and oxaliplatin plus ramucirumab with that for S-1 and oxaliplatin plus placebo in patients with advanced gastric cancer. DESIGN, SETTING, AND PARTICIPANTS This phase 2, double-blind randomized clinical trial (RAINSTORM [First-line S-1 Plus Oxaliplatin With or Without Ramucirumab Followed by Paclitaxel Plus Ramucirumab in Patients With Advanced Gastric Cancer]) was conducted from October 12, 2015, to April 11, 2018, at 36 sites in Japan, South Korea, and Taiwan. Participants were chemotherapy-naive patients (n = 189) with metastatic gastric or gastroesophageal adenocarcinoma. Analyses of the full analysis set and safety population were conducted between November 27, 2017, and June 4, 2018. INTERVENTIONS Patients randomized to the ramucirumab plus S-1 and oxaliplatin arm received S-1, 80 to 120 mg/d twice daily, on days 1 to 14 and oxaliplatin, 100 mg/m2, on day 1 with ramucirumab, 8 mg/kg, on days 1 and 8 in part A (21-day cycle). Patients randomized to the placebo plus S-1 and oxaliplatin arm received the same S-1 and oxaliplatin dosage as well as placebo on days 1 and 8 in part A. Eligible patients received second-line paclitaxel, 80 mg/m2, on days 1, 8, and 15 and ramucirumab, 8 mg/kg, on days 1 and 15 in part B (28-day cycle). MAIN OUTCOMES AND MEASURES The primary end point was progression-free survival, analyzed using the stratified log-rank test; the hazard ratio (HR) was estimated using the stratified Cox proportional hazards regression model. Secondary end points included overall survival and adverse events. RESULTS In total, 189 patients were randomized and received treatment: 96 to the ramucirumab plus S-1 and oxaliplatin arm and 93 to the placebo plus S-1 and oxaliplatin arm. Among the 189 patients, 121 (64.0%) were male, and the median (range) age was 62.0 (26-84) years. Median progression-free survival was not prolonged in the ramucirumab plus S-1 and oxaliplatin arm compared with the placebo plus S-1 and oxaliplatin arm (6.34 [80% CI, 5.65-6.93] vs 6.74 [80% CI, 5.75-7.13] months; HR, 1.07; 80% CI, 0.86-1.33; P = .70). Median overall survival was 14.65 (80% CI, 12.39-15.67) months in the ramucirumab plus S-1 and oxaliplatin arm and 14.26 (80% CI, 13.83-17.31) months in the placebo plus S-1 and oxaliplatin arm (HR, 1.11; 80% CI, 0.89-1.40; P = .55). The most commonly reported grade 3 or higher treatment-emergent adverse events in the ramucirumab plus S-1 and oxaliplatin arm in part A were decreased neutrophil count (14 patients [14.6%]), hypertension (10 patients [10.4%]), and anemia (10 patients [10.4%]). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, the addition of ramucirumab to first-line S-1 and oxaliplatin treatment did not prolong progression-free survival or overall survival compared with S-1 and oxaliplatin alone among East Asian patients with advanced gastric cancer; no new safety signals for ramucirumab were identified. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT02539225.

Abstract
BACKGROUND The standard of care for first-line treatment of recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) is combination treatment with platinum, 5-FU and cetuximab (PFE). However, this regimen requires hospitalization to ensure proper hydration and continuous infusion of 5-FU, and causes severe nausea and anorexia. We evaluated the efficacy and safety of paclitaxel, carboplatin and cetuximab (PCE) as first-line treatment in patients with R/M SCCHN. PATIENTS AND METHODS Eligibility criteria included recurrent and/or metastatic, histologically proven SCC of the oropharynx, oral cavity, hypopharynx or larynx; PS 0-1; adequate organ function; no suitable local therapy for R/M SCCHN; and no prior systemic chemotherapy for R/M SCCHN. Chemotherapy consisted of paclitaxel 100 mg/m2 on days 1, 8; carboplatin area under the blood concentration-time curve 2.5 on days 1, 8, repeated every 3 weeks for up to 6 cycles; and cetuximab at an initial dose of 400 mg/m2, followed by 250 mg/m2 weekly until disease progression or unacceptable toxicities. Primary end point was overall response rate. Secondary end points were safety, treatment completion rate, progression-free survival, overall survival, and clinical benefit rate. Planned sample size was 45 patients. RESULTS Forty-seven subjects were accrued from July 2013 to October 2014. Of 45 evaluable, 40 were male; median age was 63 years; Eastern Cooperative Oncology Group Performance Status was 0/1 in 23/22 cases; site was the hypopharynx/oropharynx/oral cavity/larynx in 17/11/10/7 cases; and 36/9 cases were smokers/nonsmokers, respectively. Overall response rate, the primary end point, was 40%. Median overall survival was 14.7 months and progression-free survival was 5.2 months. Grade 3/4 adverse events included neutropenia (68%), skin reaction (15%), fatigue (9%) and febrile neutropenia (9%). A potentially treatment-related death occurred in one patient with intestinal pneumonia. CONCLUSIONS The PCE regimen shows promising activity with acceptable toxicity in the outpatient clinic. Further studies are needed to compare PCE with PFE in this population. REGISTERED CLINICAL TRIAL NUMBER UMIN000010507.
