Intravitreal aflibercept 8 mg in neovascular age-related macular degeneration (PULSAR): 48-week results from a randomised, double-masked, non-inferiority, phase 3 trial.

BACKGROUND: Intravitreal aflibercept 8 mg could improve treatment outcomes and provide sustained disease control in patients with neovascular age-related macular degeneration (nAMD), with extended dosing compared with aflibercept 2 mg. METHODS: PULSAR is a phase 3, randomised, three-group, double-masked, non-inferiority, 96-week trial conducted across 223 sites worldwide. Adults with nAMD were randomised 1:1:1 to aflibercept 8 mg every 12 weeks (8q12), aflibercept 8 mg every 16 weeks (8q16), or aflibercept 2 mg every 8 weeks (2q8), following three initial monthly doses in all groups. From week 16, patients in the aflibercept 8 mg groups had their dosing interval shortened if pre-specified dose regimen modification criteria denoting disease activity were met. The primary endpoint was change from baseline in best-corrected visual acuity (BCVA) at week 48. All patients with at least one dose of study treatment were included in the efficacy and safety analyses. This trial is registered with ClinicalTrials.gov (NCT04423718) and is ongoing. FINDINGS: Of 1011 patients randomised to aflibercept 8q12 (n=336), 8q16 (n=338), or 2q8 (n=337) between Aug 11, 2020, and July 30, 2021, 1009 patients received study treatment (aflibercept 8q12 n=335; aflibercept 8q16 n=338; and aflibercept 2q8 n=336). Aflibercept 8q12 and 8q16 showed non-inferior BCVA gains versus aflibercept 2q8 (mean BCVA change from baseline +6·7 [SD 12·6] and +6·2 [11·7] vs +7·6 [12·2] letters). The least squares mean differences between aflibercept 8q12 versus 2q8 and 8q16 versus 2q8, respectively, were -0·97 (95% CI -2·87 to 0·92) and -1·14 (-2·97 to 0·69) letters (non-inferiority margin at 4 letters). The incidence of ocular adverse events in the study eye was similar across groups (aflibercept 8q12 n=129 [39%]; aflibercept 8q16 n=127 [38%]; and aflibercept 2q8 n=130 [39%]). INTERPRETATION: Aflibercept 8 mg showed efficacy and safety with extended dosing intervals, which has the potential to improve the management of patients with nAMD.

Intravitreal aflibercept 8 mg in diabetic macular oedema (PHOTON): 48-week results from a randomised, double-masked, non-inferiority, phase 2/3 trial.

BACKGROUND: A high-dose formulation of intravitreal aflibercept (8 mg) could improve treatment outcomes in diabetic macular oedema (DMO) by requiring fewer injections than the standard comparator, aflibercept 2 mg. We report efficacy and safety results of aflibercept 8 mg versus 2 mg in patients with DMO. METHODS: PHOTON was a randomised, double-masked, non-inferiority, phase 2/3 trial performed at 138 hospitals and specialty retina clinics in seven countries. Eligible patients were adults aged 18 years or older with type 1 or 2 diabetes and centre-involved DMO. Patients were randomly assigned (1:2:1) to intravitreal aflibercept 2 mg every 8 weeks (2q8), aflibercept 8 mg every 12 weeks (8q12), or aflibercept 8 mg every 16 weeks (8q16), following initial monthly dosing. From week 16, dosing intervals for the aflibercept 8 mg groups were shortened if patients met prespecified dose regimen modification criteria denoting disease activity. The primary endpoint was change from baseline in best-corrected visual acuity (BCVA) at week 48 (non-inferiority margin of 4 letters). Efficacy and safety analyses included all randomly assigned patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov (NCT04429503). FINDINGS: Between June 29, 2020, and June 28, 2021, 970 patients were screened for eligibility. After exclusions, 660 patients were enrolled and randomly assigned to receive aflibercept 8q12 (n=329), 8q16 (n=164), or 2q8 (n=167); two patients were randomly assigned in error and did not receive treatment. 658 (99·7%) patients were treated and included in the full analysis set and safety analysis set (8q12 n=328, 8q16 n=163, and 2q8 n=167). Mean patient age was 62·3 years (SD 10·4). 401 (61%) patients were male. 471 (72%) patients were White. Aflibercept 8q12 and 8q16 demonstrated non-inferior BCVA gains to aflibercept 2q8 (BCVA mean change from baseline 8·8 letters [SD 9·0] in the 8q12 group, 7·9 letters [8·4] in the 8q16 group, and 9·2 letters [9·0] in the 2q8 group). The difference in least squares means was -0·57 letters (95% CI -2·26 to 1·13, p value for non-inferiority <0·0001) between 8q12 and 2q8 and -1·44 letters (-3·27 to 0·39, p value for non-inferiority 0·0031) between aflibercept 8q16 and 2q8. Proportions of patients with ocular adverse events in the study eye were similar across groups (8q12 n=104 [32%], 8q16 n=48 [29%], and 2q8 n=46 [28%]). INTERPRETATION: Aflibercept 8 mg demonstrated efficacy and safety with extended dosing intervals and could decrease treatment burden in patients with DMO.

Sarilumab for Relapse of Polymyalgia Rheumatica during Glucocorticoid Taper.

BACKGROUND: More than half of patients with polymyalgia rheumatica have a relapse during tapering of glucocorticoid therapy. Previous studies have suggested that interleukin-6 blockade may be clinically useful in the treatment of polymyalgia rheumatica. Sarilumab, a human monoclonal antibody, binds interleukin-6 receptor α and efficiently blocks the interleukin-6 pathway. METHODS: In this phase 3 trial, we randomly assigned patients in a 1:1 ratio to receive 52 weeks of a twice-monthly subcutaneous injection of either sarilumab (at a dose of 200 mg) plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. The primary outcome at 52 weeks was sustained remission, which was defined as the resolution of signs and symptoms of polymyalgia rheumatica by week 12 and sustained normalization of the C-reactive protein level, absence of disease flare, and adherence to the prednisone taper from weeks 12 through 52. RESULTS: A total of 118 patients underwent randomization (60 to receive sarilumab and 58 to receive placebo). At week 52, sustained remission occurred in 28% (17 of 60 patients) in the sarilumab group and in 10% (6 of 58 patients) in the placebo group (difference, 18 percentage points; 95% confidence interval, 4 to 32; P = 0.02). The median cumulative glucocorticoid dose at 52 weeks was significantly lower in the sarilumab group than in the placebo group (777 mg vs. 2044 mg; P<0.001). The most common adverse events with sarilumab as compared with placebo were neutropenia (15% vs. 0%), arthralgia (15% vs. 5%), and diarrhea (12% vs. 2%). More treatment-related discontinuations were observed in the sarilumab group than in the placebo group (12% vs. 7%). CONCLUSIONS: Sarilumab showed significant efficacy in achieving sustained remission and reducing the cumulative glucocorticoid dose in patients with a relapse of polymyalgia rheumatica during glucocorticoid tapering.

Nanoparticle Albumin-bound Paclitaxel Plus Carboplatin Induction Followed by Nanoparticle Albumin-bound Paclitaxel Maintenance in Squamous Non-Small-cell Lung Cancer (ABOUND.sqm): A Phase III Randomized Clinical Trial.

BACKGROUND: We evaluated maintenance nanoparticle albumin-bound (nab) paclitaxel in the treatment of advanced squamous non-small-cell lung cancer. PATIENTS AND METHODS: Patients with treatment-naive squamous non-small-cell lung cancer received four 21-day cycles of nab-paclitaxel 100 mg/m2 on days 1, 8, 15 plus carboplatin area under the curve 6 on day 1 as induction therapy. Patients without disease progression after induction were randomized 2:1 to maintenance nab-paclitaxel 100 mg/m2 (days 1 and 8 every 21 days) plus best supportive care (BSC) or BSC alone. The primary endpoint was progression-free survival (PFS). Secondary endpoints included safety and overall survival (OS). RESULTS: Overall, 420 patients had received induction therapy; 202 (nab-paclitaxel plus BSC, 136; BSC, 66) had received maintenance therapy. Enrollment was discontinued after a preplanned interim futility analysis (patients could remain in the study at the investigator's discretion). The median PFS was 3.12 months for nab-paclitaxel plus BSC and 2.60 months for BSC; the difference was not statistically significant (hazard ratio [HR], 0.85; 95% confidence interval [CI], 0.61-1.19; P = .36). The median OS (median follow-up, 24.2 months) was 17.18 months for nab-paclitaxel plus BSC and 12.16 months for BSC (HR, 0.70; 95% CI, 0.48-1.02; nominal P = .07). An updated analysis (median follow-up, 28.4 months) revealed a median OS of 17.61 months for nab-paclitaxel plus BSC and 12.16 months for BSC (HR, 0.68; 95% CI, 0.47-0.98; nominal P = .037). The most frequent grade 3 and 4 treatment-emergent adverse events for the entire study were neutropenia (53.1% [nab-paclitaxel plus BSC] vs. 50.0% [BSC]) and anemia (33.1% [nab-paclitaxel plus BSC] vs. 32.3% [BSC]). Only peripheral neuropathy had occurred in ≥ 5% of patients during maintenance therapy (13.1%; nab-paclitaxel plus BSC). CONCLUSIONS: The results of the ABOUND.sqm did not meet the primary endpoint of PFS. An updated OS analysis revealed a trend favoring nab-paclitaxel plus BSC.

Analysis of the Role of Plasma 25-Hydroxyvitamin D Levels in Survival Outcomes in Patients from the Phase III MPACT Trial of Metastatic Pancreatic Cancer.

BACKGROUND: We examined overall survival (OS) outcomes based on plasma 25-hydroxyvitamin D [25(OH)D] levels in this post hoc analysis of the phase III MPACT trial of metastatic pancreatic cancer. MATERIALS AND METHODS: Patients were subdivided based on 25(OH)D level: sufficient (≥30 ng/mL), relatively insufficient (20-<30 ng/mL), or insufficient (<20 ng/mL). RESULTS: Of 861 patients randomized in MPACT, 422 were included in this analysis. In the all-patients group, the median OS among those with insufficient, relatively insufficient, and sufficient 25(OH)D levels was 7.9, 9.4, and 7.8 months, respectively. No statistically significant OS difference was observed with relatively insufficient (p = .227) or sufficient (p = .740) versus insufficient 25(OH)D levels or with sufficient vs relatively insufficient (p = .301) 25(OH)D levels. CONCLUSION: No association was observed between plasma 25(OH)D levels and survival. Further investigations are needed to understand any role of vitamin D in pancreatic cancer.

Open-label, Phase I Study of Nivolumab Combined with nab-Paclitaxel Plus Gemcitabine in Advanced Pancreatic Cancer.

PURPOSE: Assess safety and efficacy of nivolumab plus nab-paclitaxel and gemcitabine in patients with locally advanced/metastatic pancreatic cancer in a two-part, open-label, phase I trial. PATIENTS AND METHODS: Fifty chemotherapy-naive patients received nab-paclitaxel 125 mg/m2 plus gemcitabine 1,000 mg/m2 (days 1, 8, and 15) and nivolumab 3 mg/kg (days 1 and 15) in 28-day cycles. The primary endpoints were dose-limiting toxicities (DLTs; part 1) and grade 3/4 treatment-emergent adverse events (TEAEs) or treatment discontinuation due to TEAEs (parts 1/2). Secondary efficacy endpoints were progression-free survival (PFS), overall survival (OS), and response. Assessment of programmed cell death-ligand 1 (PD-L1) expression was an exploratory endpoint; additional biomarkers were assessed post hoc. RESULTS: One DLT (hepatitis) was reported in part 1 among six DLT-evaluable patients; 48 of 50 patients experienced grade 3/4 TEAEs and 18 discontinued treatment due to TEAEs. One grade 5 TEAE (respiratory failure) was reported. Median [95% confidence interval (CI)] PFS/OS was 5.5 (3.25-7.20 months)/9.9 (6.74-12.16 months) months, respectively [median follow-up for OS, 13.6 months (95% CI, 12.06-23.49 months)]. Overall response rate (95% CI) was 18% (8.6%-31.4%). Median PFS/OS was 5.5/9.7 months (PD-L1 <5%) and 6.8/11.6 months (PD-L1 ≥5%), respectively. Proportion of peripheral Ki67+ CD8+/CD4+ cells increased significantly from baseline to cycle 3; median peak on-treatment Ki67+ CD8+ T-cell values were higher in responders than in nonresponders. CONCLUSIONS: The safety profile of nivolumab plus nab-paclitaxel and gemcitabine at standard doses in advanced pancreatic cancer was manageable, with no unexpected safety signals. Overall, the clinical results of this study do not support further investigation.

Quality of life with second or third line nab-paclitaxel-based regimens in advanced non-small-cell lung cancer.

Aim: Evaluate quality of life (QoL) in patients with advanced non-small cell lung cancer treated with second or third line nab-paclitaxel ± durvalumab. Patients & methods: Longitudinal QoL was assessed using Lung Cancer Symptom Scale, EuroQoL Five-Dimensions Five-Levels and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item core. Results: QoL was generally stable through eight treatment cycles (both arms). Clinically meaningful improvement from baseline was noted in Lung Cancer Symptom Scale (overall constitutional score and three-item index [nab-paclitaxel + durvalumab]) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item core (global health status/QoL and emotional functioning [both arms] and pain [nab-paclitaxel + durvalumab]) analyses. EuroQoL Five-Dimensions Five-Levels domains were stable/improved or completely resolved at least once in 19-56% and 9-51% of patients, respectively. Conclusion: While QoL trends were promising, additional data are required to support these regimens in this setting.

nab-Paclitaxel Plus Durvalumab in Patients With Previously Treated Advanced Stage Non-small Cell Lung Cancer (ABOUND.2L+).

Background: The standard therapy for advanced stage non-small cell lung cancer (NSCLC) with no actionable gene alterations is a platinum-based chemotherapy doublet and immune checkpoint blocker (ICB), either concurrently or sequentially, followed by docetaxel at the time of tumor progression. However, more effective treatments are needed. We evaluated the nab-paclitaxel and durvalumab combination in patients with previously treated advanced stage NSCLC. Methods: Patients with advanced stage NSCLC previously treated with one line of platinum-based doublet with or without an ICB and no activating EGFR mutations or ALK translocations received nab-paclitaxel 100 mg/m2 (days 1 and 8) plus durvalumab 1,125 mg (day 15) every 21 days. The primary endpoint was progression-free survival (PFS). Key secondary endpoints included overall survival (OS) and safety. Results: Between February 2016 and December 2016, 79 patients were enrolled. The median age was 63 years. Most patients were males (68.4%), had non-squamous histology (69.6%), and had no prior ICB treatment (88.6%). The median PFS was 4.5 months; median OS was 10.1 months. A post hoc analysis of survival by prior ICB treatment revealed a median PFS and OS of 4.4 and 9.9 months, respectively, in ICB-naive patients and 6.9 months and not estimable, respectively, in patients previously treated with ICB. The most common treatment-emergent adverse events were asthenia (46.2%) and diarrhea (34.6%); four treatment-related deaths (5.1%) occurred. Conclusions: The nab-paclitaxel and durvalumab combination is feasible and demonstrated antitumor activity without new safety signals. Additional studies using taxanes and ICB in patients with previously treated NSCLC are warranted. Clinical Trial Registration: ClinicalTrials.gov registration (NCT02250326).

nab-Paclitaxel/Carboplatin in Vulnerable Populations With Advanced Non-Small Cell Lung Cancer: Pooled Analysis.

INTRODUCTION: Despite improvements in the treatment of advanced non-small cell lung cancer (NSCLC), certain patient populations remain underrepresented in clinical trials. Many patients have benefited from platinum doublets, including nab-paclitaxel-based regimens, but there are patients with comorbidities who particularly require careful balancing of efficacy and safety. Clinical trial data are limited for patients who are elderly or have renal impairment, diabetes, or impaired performance status. METHODS: To better understand outcomes in these patient populations, we performed a pooled analysis using data from the ABOUND clinical trial program (ABOUND.SQM, ABOUND.PS2, ABOUND.70+) and the key phase III trial of nab-paclitaxel/carboplatin in advanced NSCLC. The populations included in this pooled analysis consisted of elderly patients (≥ 70 years) and patients with renal impairment (eGFR < 60 ml/min/1.73 m2), diabetes, or poor performance status (ECOG PS 2). RESULTS: Median progression-free survival (PFS) ranged from 4.1 months in patients with ECOG PS 2 (95% CI, 2.04-5.09 months) to 7.7 months in patients with diabetes (95% CI, 5.88-10.12 months). PFS for elderly patients and patients with renal impairment was 6.9 months each (95% CI, 6.01-7.98 months and 4.47-9.79 months, respectively). Median overall survival (OS) was 18.2 months (95% CI, 10.94-28.22 months), 17.4 months (95% CI, 14.59-20.14 months), and 16.1 months (95% CI, 14.09-18.50 months) in patients with renal impairment, patients with diabetes, and elderly patients, respectively. Patients with ECOG PS 2 exhibited the shortest median OS: 5.6 months (95% CI, 3.98-11.37 months). Overall response rates were 56.9%, 54.6%, 45.9%, and 29.4% in patients with diabetes, elderly patients, patients with renal impairment, and patients with ECOG PS 2, respectively. Most treatment-related adverse events were hematologic. The most common grade 3/4 hematologic adverse events in patients with renal impairment, elderly patients, patients with diabetes, and patients with poor performance status included neutropenia, anemia, and thrombocytopenia. CONCLUSIONS: Although survival data in patients with ECOG PS 2 were notably inferior to the other cohorts, our findings are consistent with those previously reported in the population-specific studies of the ABOUND trials and lend additional support for the use of nab-paclitaxel-based regimens in historically understudied and vulnerable populations.

Safety and Efficacy Results of a Phase I, Open-Label Study of Concurrent and Delayed Nivolumab in Combination With nab-Paclitaxel and Carboplatin in Advanced Non-small Cell Lung Cancer.

Introduction: Multicenter, phase I study of concurrent and delayed nivolumab plus nab-paclitaxel/carboplatin in advanced non-small cell lung cancer (NSCLC). Methods: Chemotherapy-naive patients with advanced NSCLC (ineligible for potentially curative radiation or surgery) received nab-paclitaxel 100 mg/m2 (days 1, 8, 15) and carboplatin area under the curve 6 (day 1) intravenously every 21 days (first 4 cycles); nivolumab 5 mg/kg was administered intravenously (day 15) beginning in cycle 1 (concurrent) or cycle 3 (delayed) in separate cohorts and continued beyond the 4 chemotherapy cycles. The primary objective was to assess safety. Secondary objectives were to assess tolerability and explore antitumor activity. Results: All 32 patients received chemotherapy; 20 of 22 and 6 of 10 patients also received concurrent or delayed nivolumab, respectively. No dose-limiting toxicities were reported in the concurrent cohort; 1 dose-limiting toxicity was reported in the delayed cohort. In the concurrent cohort, 20 patients (91%) had ≥1 grade 3/4 treatment-emergent adverse event (TEAE), and 7 (32%) discontinued treatment due to TEAEs. In the delayed cohort, all patients had ≥1 grade 3/4 TEAE, and 2 (20%) discontinued due to TEAEs. The median progression-free and overall survival, respectively, were 10.5 and 29.3 months in the concurrent cohort and 4.1 and 8.2 months in the delayed cohort. Conclusions: The safety profile of the combination was consistent with that of individual agents and generally similar in the 2 cohorts. Efficacy outcomes in the concurrent cohort, but not in the delayed cohort, were encouraging and support the rationale for concurrent administration of nivolumab with nab-paclitaxel/carboplatin for the treatment of advanced NSCLC.

A Phase I/II Open-Label Multicenter Single-Arm Study of FABLOx (Metronomic 5-Fluorouracil Plus nab-Paclitaxel, Bevacizumab, Leucovorin, and Oxaliplatin) in Patients with Metastatic Pancreatic Cancer.

Purpose: To evaluate safety and preliminary efficacy of metronomic 5-fluorouracil plus nab-paclitaxel, bevacizumab, leucovorin, and oxaliplatin (FABLOx) in patients with newly diagnosed metastatic pancreatic cancer (MPC). Methods: A total of 12 treatment-naive patients (aged 18-65 years, Eastern Cooperative Oncology Group performance status [ECOG PS] ≤1) with MPC received 5-fluorouracil 180 mg/m2 per day (days 1-14 continuous infusion); nab-paclitaxel 75 mg/m2, leucovorin 20 mg/m2, and oxaliplatin 40 mg/m2 (days 1, 8, and 15); and bevacizumab 5 mg/kg (days 1 and 15) administered intravenously in each 28-day cycle. The primary end-point was incidence of dose-limiting toxicities (DLTs) in cycle 1. Safety was further evaluated as a secondary end-point; preliminary efficacy was also examined. Results: Two DLTs (grade 3 anemia requiring transfusion and grade 3 mucositis unresponsive to treatment within 4 days of onset) were observed in one of six patients enrolled in dose cohort 1. Cohort 1 was expanded from 6 to 12 patients to further evaluate safety, per the investigators' recommendation. All patients discontinued treatment. The most common grade ≥3 adverse events were abdominal pain, fatigue, mucositis, and decreased neutrophil count. Objective response rate was 33% (four partial responses). Median progression-free survival (PFS) and overall survival (OS) were 5.6 (95% confidence interval [CI], 1.7-11.3) and 9.9 (95% CI, 4.4-13.2) months, respectively; 1-year PFS and OS rates were 12.2% (95% CI, 0.7-40.8) and 38.9% (95% CI, 12.6-65.0). Conclusion: FABLOx is feasible and tolerable in patients newly diagnosed with MPC. However, preliminary efficacy data are inconclusive for continued investigation in a phase II trial.

Association between depth of response and survival in patients with advanced-stage non-small cell lung cancer treated with first-line chemotherapy.

BACKGROUND: A partial response according to the Response Evaluation Criteria in Solid Tumors includes a wide range of changes in tumor size. This study evaluated whether further specification of tumor reduction based on the depth of response (DpR) would provide a more precise association with outcomes for patients with non-small cell lung cancer (NSCLC) treated with first-line platinum-based chemotherapy. METHODS: A retrospective analysis was performed for the randomized phase 3 CA031 trial in patients with NSCLC treated with carboplatin in combination with nab-paclitaxel or solvent-based paclitaxel. Quartiles according to the maximum tumor reduction from the baseline were defined (quartile 1 [Q1], >0% to 25%; quartile 2 [Q2], >25% to 50%; quartile 3 [Q3], >50% to 75%; and quartile 4 [Q4], >75%) and were compared with those patients with no tumor reduction (NTR). The primary objective was to evaluate the association between DpR and overall survival (OS). RESULTS: Of the 1052 patients enrolled in the CA031 trial, 959 (91%) were evaluable, and they included 365 (38.1%) who were classified as Q1, 327 (34.1%) who were classified as Q2, 131 (13.7%) who were classified as Q3, and 34 (3.5%) who were classified as Q4; 102 had NTR (10.6%). The median OS values for patients in the NTR, Q1, Q2, Q3, and Q4 groups were 4.8, 10.4, 14.5, 19.3, and 23.5 months, respectively. The maximum DpR on treatment was an independent predictor of improved OS in comparison with patients with NTR; the hazard ratio decreased from 0.43 in Q1 to 0.16 in Q4. CONCLUSIONS: DpR was strongly associated with OS in patients with NSCLC receiving first-line platinum-based therapy. Additional studies may help to define the role of DpR in solid tumors.

ABOUND.2L+: A randomized phase 2 study of nanoparticle albumin-bound paclitaxel with or without CC-486 as second-line treatment for advanced nonsquamous non-small cell lung cancer (NSCLC).

BACKGROUND: This randomized phase 2 trial compared the efficacy and safety of second-line nanoparticle albumin-bound paclitaxel (nab-paclitaxel) with or without the addition of CC-486 (an oral formulation of 5-azacytidine) in patients with advanced-stage, nonsquamous non-small cell lung cancer. METHODS: Patients were randomized to receive either nab-paclitaxel 100 mg/m2 on days 8 and 15 plus CC-486 200 mg daily on days 1 to 14 or single-agent nab-paclitaxel 100 mg/m2 on days 1 and 8, with both regimens administered every 21 days until tumor progression or unacceptable toxicity. The primary endpoint was progression-free survival. Secondary endpoints included the overall response rate, the disease control rate, and overall survival. RESULTS: Between January 2015 and August 2016, 161 patients were randomized (81 to the combination arm and 80 to the single-agent nab-paclitaxel arm). There was no benefit from the addition of CC-486 to nab-paclitaxel. The median progression-free survival was 3.2 months for the combination and 4.2 months for single-agent nab-paclitaxel (hazard ratio, 1.3; 95% confidence interval, 0.9-1.9). The median overall survival was 8.1 months in the combination arm and 17 months in the single-agent nab-paclitaxel arms (hazard ratio, 1.7; 95% confidence interval, 1.08-2.57). Grade 3 or greater treatment-related, emergent adverse events were reported by 40.5% of patients in the combination arm and by 31.6% of those in the single-agent nab-paclitaxel arm. CONCLUSIONS: Single-agent nab-paclitaxel was associated with promising outcomes and a tolerable safety profile as second-line treatment for patients with advanced-stage, nonsquamous non-small cell lung cancer. There was no benefit from the addition of CC-486 to nab-paclitaxel.

Nivolumab Plus Ipilimumab in Patients With Advanced Melanoma: Updated Survival, Response, and Safety Data in a Phase I Dose-Escalation Study.

Purpose The clinical activity observed in a phase I dose-escalation study of concurrent therapy with nivolumab (NIVO) and ipilimumab (IPI) in patients with previously treated or untreated advanced melanoma led to subsequent clinical development, including randomized trials. Here, we report long-term follow-up data from study CA209-004, including 3-year overall survival (OS). Patients and Methods Concurrent cohorts 1, 2, 2a, and 3 received escalating doses of NIVO plus IPI once every 3 weeks for four doses, followed by NIVO once every 3 weeks for four doses, then NIVO plus IPI once every 12 weeks for eight doses. An expansion cohort (cohort 8) received concurrent NIVO 1 mg/kg plus IPI 3 mg/kg once every 3 weeks for four doses, followed by NIVO 3 mg/kg once every 2 weeks, which is the dose and schedule used in phase II and III studies and now approved for patients with unresectable or metastatic melanoma. Results Among all concurrent cohorts (N = 94) at a follow-up of 30.3 to 55.0 months, the 3-year OS rate was 63% and median OS had not been reached. Objective response rate by modified WHO criteria was 42%, and median duration of response was 22.3 months. Incidence of grade 3 and 4 treatment-related adverse events was 59%. The most common grade 3 and 4 treatment-related adverse events were increases in lipase (15%), alanine aminotransferase (12%), and aspartate aminotransferase (11%). One treatment-related death (1.1%) occurred in a patient who had multiorgan failure 70 days after the last dose of NIVO plus IPI. Conclusion This is the longest follow-up for NIVO plus IPI combination therapy in patients with advanced melanoma. The 3-year OS rate of 63% is the highest observed for this patient population and provides additional evidence for the durable clinical activity of immune checkpoint inhibitors in the treatment of advanced melanoma.

Overall Survival with Combined Nivolumab and Ipilimumab in Advanced Melanoma.

BACKGROUND: Nivolumab combined with ipilimumab resulted in longer progression-free survival and a higher objective response rate than ipilimumab alone in a phase 3 trial involving patients with advanced melanoma. We now report 3-year overall survival outcomes in this trial. METHODS: We randomly assigned, in a 1:1:1 ratio, patients with previously untreated advanced melanoma to receive nivolumab at a dose of 1 mg per kilogram of body weight plus ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses, followed by nivolumab at a dose of 3 mg per kilogram every 2 weeks; nivolumab at a dose of 3 mg per kilogram every 2 weeks plus placebo; or ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses plus placebo, until progression, the occurrence of unacceptable toxic effects, or withdrawal of consent. Randomization was stratified according to programmed death ligand 1 (PD-L1) status, BRAF mutation status, and metastasis stage. The two primary end points were progression-free survival and overall survival in the nivolumab-plus-ipilimumab group and in the nivolumab group versus the ipilimumab group. RESULTS: At a minimum follow-up of 36 months, the median overall survival had not been reached in the nivolumab-plus-ipilimumab group and was 37.6 months in the nivolumab group, as compared with 19.9 months in the ipilimumab group (hazard ratio for death with nivolumab plus ipilimumab vs. ipilimumab, 0.55 [P<0.001]; hazard ratio for death with nivolumab vs. ipilimumab, 0.65 [P<0.001]). The overall survival rate at 3 years was 58% in the nivolumab-plus-ipilimumab group and 52% in the nivolumab group, as compared with 34% in the ipilimumab group. The safety profile was unchanged from the initial report. Treatment-related adverse events of grade 3 or 4 occurred in 59% of the patients in the nivolumab-plus-ipilimumab group, in 21% of those in the nivolumab group, and in 28% of those in the ipilimumab group. CONCLUSIONS: Among patients with advanced melanoma, significantly longer overall survival occurred with combination therapy with nivolumab plus ipilimumab or with nivolumab alone than with ipilimumab alone.

Pooled Analysis Safety Profile of Nivolumab and Ipilimumab Combination Therapy in Patients With Advanced Melanoma.

Purpose The addition of nivolumab (anti-programmed death-1 antibody) to ipilimumab (anti-cytotoxic T-cell lymphocyte-associated 4 antibody) in patients with advanced melanoma improves antitumor response and progression-free survival but with a higher frequency of adverse events (AEs). This cross-melanoma study describes the safety profile of the approved nivolumab plus ipilimumab regimen. Methods This retrospective safety review on data from three trials (phase I, II, and III) included patients with advanced melanoma who received at least one dose of nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks × 4 and then nivolumab 3 mg/kg every 2 weeks until disease progression or unacceptable toxicity while following established guidelines for AE management. Analyses were of all treatment-related AEs, select (immune-related) AEs, time to onset and resolution, and use of immune-modulating agents and their effects on outcome. Results Among 448 patients, median duration of follow-up was 13.2 months. Treatment-related grade 3/4 AEs occurred in 55.5% of patients; 35.7% had treatment-related AEs that led to discontinuation. The most frequent treatment-related select AEs of any grade were skin (64.3%) and GI (46.7%) and of grade 3/4, hepatic (17.0%) and GI (16.3%); 30.1% developed a grade 2 to 4 select AE in more than one organ category. Median time to onset of grade 3/4 treatment-related select AEs ranged from 3.1 (skin) to 16.3 (renal) weeks, and with the exclusion of endocrine AEs, median time to resolution from onset ranged from 1.9 (renal) to 4.5 (pulmonary) weeks, with resolution rates between 79% and 100% while using immune-modulating agents. Four (< 1%) on-study deaths were attributed to therapy. Conclusion Frequency of grade 3/4 treatment-related AEs was higher with nivolumab plus ipilimumab and occurred earlier than historical experience with either agent alone, but resolution rates were similar.

Efficacy and Safety Outcomes in Patients With Advanced Melanoma Who Discontinued Treatment With Nivolumab and Ipilimumab Because of Adverse Events: A Pooled Analysis of Randomized Phase II and III Trials.

Purpose Approximately 40% of patients with advanced melanoma who received nivolumab combined with ipilimumab in clinical trials discontinued treatment because of adverse events (AEs). We conducted a retrospective analysis to assess the efficacy and safety of nivolumab plus ipilimumab in patients who discontinued treatment because of AEs. Methods Data were pooled from phase II and III trials of patients who received nivolumab 1 mg/kg plus ipilimumab 3 mg/kg, every 3 weeks for four doses, followed by nivolumab monotherapy 3 mg/kg every 2 weeks (N = 409). Efficacy was assessed in all randomly assigned patients who discontinued because of AEs during the induction phase (n = 96) and in those who did not discontinue because of AEs (n = 233). Safety was assessed in treated patients who discontinued because of AEs (n = 176) at any time and in those who did not discontinue because of AEs (n = 231). Results At a minimum follow-up of 18 months, median progression-free survival was 8.4 months for patients who discontinued treatment because of AEs during the induction phase and 10.8 months for patients who did not discontinue because of AEs ( P = .97). Median overall survival had not been reached in either group ( P = .23). The objective response rate was 58.3% for patients who discontinued because of AEs during the induction phase and 50.2% for patients who did not discontinue. The vast majority of grade 3 or 4 AEs occurred during the induction phase, with most resolving after appropriate management. Conclusion Efficacy outcomes seemed similar between patients who discontinued nivolumab plus ipilimumab treatment because of AEs during the induction phase and those who did not discontinue because of AEs. Therefore, even after discontinuation, many patients may continue to derive benefit from combination therapy.

Clinical judgment does not circumvent the need for diagnostic endoscopy in upper gastrointestinal hemorrhage.

BACKGROUND: To better understand the ability of physicians to predict the need for endoscopic therapy and to accurately predict specific endoscopic lesions, we performed a prospective, nonrandomized, observational cohort study in patients presenting with upper gastrointestinal hemorrhage (UGIH) who were undergoing endoscopy. AIM: We aimed to evaluate the pre-endoscopy diagnostic accuracy and the correct prediction of high-risk lesions in patients with UGIH according to the level of clinical expertise. METHODS: One hundred twenty-one patients presenting with hematemesis and/or melena within 48 hours were studied. A questionnaire was given to primary physicians, gastroenterology fellows, and gastroenterology faculty, asking them to predict the need for endoscopic therapy and the cause of the bleed. RESULTS: The need for endoscopic therapy was predicted accurately by 68% of the primary physicians, 70% of the fellows, and 74% of the faculty physicians (P = 0.61). The faculty were able to predict which patients did not need therapy more accurately than the fellows and the residents: 85%, 78%, and 68%, respectively (P = 0.03). The diagnostic accuracy of the clinicians--that is, the ability to accurately predict the bleeding lesion among the primary physicians, fellows, and faculty physicians, was similar at 46%, 52%, and 48%, respectively (P = 0.65). CONCLUSIONS: The accuracy of predicting the need for endoscopic therapy and the culprit cause of UGIH, based on clinical evaluation, was similar across levels of expertise. However, the faculty gastroenterologists were better than the gastroenterology fellows and the primary providers in predicting which patients do not require endoscopic treatment. We conclude that the relative inability of any group of physicians to accurately predict the presence of high-risk lesions requiring endoscopic therapy suggests that most patients with UGIH should undergo upper endoscopy for diagnosis and possible therapy.

Solid organ transplant recipients presenting for Mohs micrographic surgery: a retrospective case-control study.

BACKGROUND: Solid organ transplant recipients (SOTR) have a high risk of cutaneous malignancy. Mohs micrographic surgery (MMS) is recommended for the treatment of skin cancers in this group. The characteristics of the tumors in SOTR presenting for MMS are not well documented. OBJECTIVE: To describe the characteristics of tumors in SOTR presenting to a single institution over an 11-year period and compare them with tumors of non-SOTR who have also undergone MMS. METHODS: A database query captured patients with a current organ transplant who underwent MMS. These patients (cases) were matched to controls who also underwent MMS. Statistical models were used to identify tumor and operative characteristics significantly associated with SOTR compared with matching controls. RESULTS: Ninety-two SOTR underwent MMS for 432 skin cancers; 163 controls had 269 skin cancers. Squamous cell carcinoma (SCC) was the most common tumor in SOTR, with a reversal of the usual ratio of basal cell carcinoma to SCC. Mean tumor and defect sizes were similar in SOTR and controls. Cardiac transplants were the predominant transplant. CONCLUSIONS: SOTR referred for MMS have disproportionately more and different types of skin cancers than controls.

The hematocrit level in upper gastrointestinal hemorrhage: safety of endoscopy and outcomes.

OBJECTIVE: In patients with acute upper gastrointestinal hemorrhage, standard practice is to transfuse packed red blood cells, often to an arbitrary level of hemoglobin or hematocrit (typically 10 g/dL and 30%, respectively) before endoscopy. Therefore, we aimed to determine first whether performing endoscopy in patients with upper gastrointestinal hemorrhage and a low hematocrit is safe and whether it predicts outcomes. METHODS: This cohort study included patients with carefully defined upper gastrointestinal hemorrhage captured in our gastrointestinal Healthcare Registry who underwent esophagogastroduodenoscopy. Patients were placed into 2 groups: low hematocrit (<30%) or high hematocrit (>30%). Clinical variables and outcomes, including cardiovascular events, intensive care unit transfer, and death, were measured. RESULTS: A total of 920 patients meeting entry criteria were identified. Baseline features among those with a low and high hematocrit were identical. Eight cardiovascular events occurred during or after esophagogastroduodenoscopy, including 5 of 587 (1%) in the less than 30% hematocrit group and 3 of 333 (1%) in the greater than 30% hematocrit group (P=.29). Blood transfusions were more common in the low hematocrit group (74% vs 24%, P<.001). However, correlation between the amount of blood transfused and hematocrit level was poor, and the number units of blood transfused was highly variable. There was no significant mortality difference in the 2 hematocrit groups. CONCLUSION: Most patients with upper gastrointestinal hemorrhage presented with a hematocrit less than 30%. Performing endoscopy in patients with a low hematocrit was clearly safe; these data strongly imply that waiting for the hematocrit to reach a certain level before endoscopy is not necessary.
