RESUMO

Single-arm trials (SATs), while not preferred, remain in use throughout the drug development cycle. They may be accepted by regulators in particular contexts (e.g., in oncology or rare diseases) when the potential effects of new treatments are very large and placebo treatment is unethical. However, in the postregulatory space, SATs are common, and perhaps even more poorly suited to address the questions of interest. In this manuscript, we review regulatory and HTA positions on SATs; challenges posed by SATs to address research questions beyond regulators, evolving statistical methods to provide context for SATs, case studies where SATs could and could not address questions of interest, and communication strategies to influence decision making and optimize study design to address evidence needs.

RESUMO

PURPOSE: PIK3CA-related overgrowth spectrum (PROS) encompasses several rare conditions resulting from activating variants in PIK3CA. Alpelisib, a PI3Kα-selective inhibitor, targets the underlying etiology of PROS, offering a novel therapeutic approach to current management strategies. This study evaluated the safety and efficacy of alpelisib in pediatric and adult patients with PROS. METHODS: EPIK-P1 (NCT04285723) was a non-interventional, retrospective chart review of 57 patients with PROS (≥2 years) treated with alpelisib through compassionate use. Patients had severe/life-threatening PROS-related conditions and confirmed PIK3CA pathogenic variant. The primary end point assessed patient response to treatment at Week 24 (6 months). RESULTS: Twenty-four weeks (6 months) after treatment initiation, 12 of 32 (37.5%) patients with complete case records included in the analysis of the primary end point experienced a ≥20% reduction in target lesion(s) volume. Additional clinical benefit independent from lesion volume reduction was observed across the full study population. Adverse events (AEs) and treatment-related AEs were experienced by 82.5% (47/57) and 38.6% (22/57) of patients, respectively; the most common treatment-related AEs were hyperglycemia (12.3%) and aphthous ulcer (10.5%). No deaths occurred. CONCLUSION: EPIK-P1 provides real-world evidence of alpelisib effectiveness and safety in patients with PROS and confirms PI3Kα as a valid therapeutic target for PROS symptom management.

RESUMO

Rare disorders impact millions of children worldwide, and developing new medicines in this setting is associated with multiple challenges. In this paper, we share a successful story of how real-world data (RWD) were leveraged to accelerate evidence generation and patient access to a life-changing therapy in patients with severe manifestations of PIK3CA-related overgrowth spectrum who require systemic therapy. Despite all the existing regulatory guidelines considering real-world evidence (RWE), there is limited regulatory precedent of the use of this framework in support of a new indication. Thus, our case study illustrates design innovations based on the use of a compassionate use program, primarily in children, as a RWD source for approval of a new therapy in a rare disorder. We highlight the systematic considerations and mitigation of potential sources of bias in order to transform the data into actionable evidence. Our experience shows that RWE can be successfully used with appropriate study planning and mitigation in the context of a rare disorder with a high unmet medical need. Some lessons learned from this case study can benefit therapeutic development in rare disorders.

RESUMO

BACKGROUND: Approximately 40% of hormone receptor positive/human epidermal receptor 2 negative (HR + /HER2-) metastatic breast cancer (mBC) patients harbor phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) mutations. However, associations between PIK3CA mutation status and clinical outcomes among patients with HR + /HER2- mBC have been heterogeneous across clinical trials. This meta-analysis was conducted to survey recently available trial data to assess the prognostic effects of PIK3CA among patients with HR + /HER2- mBC.  METHODS: Randomized clinical trials reporting progression-free survival (PFS) or overall survival (OS) stratified by PIK3CA status in HR + /HER2- mBC were identified via systematic literature review. Trial arms receiving phosphatidylinositol 3-kinase (PI3K)-targeted therapies were excluded. Meta-regression analysis was used to estimate the association between PIK3CA status and PFS and OS among included studies. RESULTS: The analyzed data included 3,219 patients from 33 study arms across 11 trials (PIK3CA mutated: 1,386, wild type: 1,833). PIK3CA mutation was associated with shorter median PFS (difference [95% CI] (months): -1.8 [-3.4, -0.1], I2 = 35%) and shorter median OS (-8.4 [-13.4, -3.5], I2 = 58%, N = 1,545). Findings were similar for PFS rates at 6 months (odds ratio [95% CI]: 0.74 [0.59, 0.94], I2 = 42%, N = 3,160) and 12 months (0.76 [0.59, 0.99], I2 = 42%, N = 2,468) and directionally consistent but not statistically significant at 18 months (N = 1,726). CONCLUSIONS: Pooling evidence across multiple studies, PIK3CA mutation was associated with shorter PFS and OS. These findings suggest a negative prognostic value of PIK3CA mutations in patients with HR + /HER2- mBC.

RESUMO

BACKGROUND: Hyperglycemia and hypercholesterolemia are class effects of mammalian target of rapamycin inhibitors such as everolimus. This post hoc pooled analysis assessed the potential impact of these events on the efficacy of everolimus. METHODS: Patients with advanced, low- or intermediate-grade pancreatic, gastrointestinal, or lung neuroendocrine tumors received either oral everolimus at 10 mg/d or a placebo in the RAD001 in Advanced Neuroendocrine Tumors 3 (RADIANT-3) and RAD001 in Advanced Neuroendocrine Tumors 4 (RADIANT-4) trials. A landmark progression-free survival (PFS) analysis by central review was performed for patients treated for at least 16 weeks (n = 308) and according to the occurrence of any-grade adverse events (AEs) within this treatment period. RESULTS: The overall PFS with everolimus from the pooled analysis was 11.4 months (95% confidence interval, 11.01-13.93 months), which was consistent with the findings of RADIANT-3 and RADIANT-4. Overall, 19.1% and 9.8% of patients in RADIANT-3 and 11.9% and 6.4% of patients in RADIANT-4 developed any-grade hyperglycemia and hypercholesterolemia, respectively (regardless of the study drug). The duration of everolimus exposure was longer in patients who developed these AEs versus patients without these AEs. Overall, 308 patients were exposed to treatment for at least 16 weeks (hyperglycemia, 39 of 269 patients; hypercholesterolemia, 20 of 288 patients). No association was observed between the development of these AEs and PFS (18.8 and 14.1 months with and without hyperglycemia, respectively, and 14.1 and 14.8 months with and without hypercholesterolemia, respectively). CONCLUSIONS: Although limitations apply because of the small number of AEs observed, there was no significant impact of these AEs on PFS; this suggests similar efficacy in the presence or absence of these events.

RESUMO

BACKGROUND: This pooled analysis of MONALEESA trials evaluated the safety of ribociclib plus endocrine therapy (RIB + ET) with a focus on dose reductions in first-line patients. METHODS: In the dose reduction analysis, data were pooled from MONALEESA-2 (all patients), MONALEESA-3 (patients receiving treatment as first-line ET) and MONALEESA-7 (patients receiving combination therapy with an NSAI as initial ET). Efficacy was analysed by ribociclib relative dose intensity (DI). Safety was analysed in all patients in the trials (except those receiving tamoxifen in MONALEESA-7) and those with/without ≥1 ribociclib dose reduction. RESULTS: Of 818 women who received first-line RIB + ET, 41.8% required ≥1 dose reduction due to AEs (most commonly, neutropenia). Median RIB relative DI in patients without and with dose reductions was 99.3% and 65.6% in MONALEESA-2, 98.4% and 67.8% in MONALEESA-3 and 98·0% and 66·3% in MONALEESA-7. Median PFS was 24.8, 24.9 and 29.6 months for patients who received ≤71% (30th percentile), 72-96% (60th percentile) and 97-100% (90th percentile) RIB relative DI, respectively. No new safety signals emerged in the pooled safety analysis. CONCLUSIONS: This analysis provides reassuring data showing that the clinical benefit of RIB is preserved when dose modifications are undertaken to manage AEs.

RESUMO

BACKGROUND: The BYLieve trial (NCT03056755) confirmed efficacy and safety of alpelisib with fulvestrant for hormone receptor-positive (HR+), human epidermal growth factor receptor-2-negative (HER2-), PIK3CA-mutated advanced breast cancer (ABC), after cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) with an aromatase inhibitor (AI) as immediate prior therapy. Further analyses were performed to compare efficacy from BYLieve with effectiveness of standard treatment in the real-world setting. MATERIALS AND METHODS: Patients who progressed on a CDK4/6i plus AI and were treated with alpelisib with fulvestrant in BYLieve were matched with a real-world patient cohort who received standard-of-care from a deidentified clinico-genomics database (CGDB). Primary and secondary endpoints were to compare progression-free survival (PFS), estimated by the Kaplan-Meier method, and the proportion of patients remaining progression-free at 6 months, respectively, between the two cohorts. RESULTS: A total of 855 patients with PIK3CA-mutant disease who had prior CDK4/6i plus hormone therapy were selected from the CGDB; further matching to 120 patients from BYLieve selected 95 patients without exposure to HER2-targeting agents, clinical study drug, or alpelisib. In unadjusted and postmatching results, primary and secondary endpoints favored treatment with alpelisib with fulvestrant in BYLieve more than standard treatments in the real-world cohort. Postadjustment, median PFS for patients treated with alpelisib in BYLieve was 7.3 versus 3.7 months in the real-world cohort, and 6-month PFS was 54.6% versus 40.1%, respectively. CONCLUSION: Matched/weighted analysis comparing BYLieve with the real-world setting further supports the clinical benefit of alpelisib with fulvestrant for treatment of HR+, HER2-, PIK3CA-mutant ABC after CDK4/6i treatment. IMPLICATIONS FOR PRACTICE: Approximately 40% of patients with hormone receptor-positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) advanced breast cancer (ABC) have PIK3CA-mutated tumors, which have been associated with endocrine therapy resistance. Alpelisib, an α-selective phosphatidylinositol-3-kinase inhibitor, demonstrated significantly improved progression-free survival in SOLAR-1 and demonstrated clinical efficacy in BYLieve when combined with fulvestrant. Data are limited in comparing the efficacy of alpelisib combined with fulvestrant with effectiveness of standard therapy after CDK4/6i treatment. Using real-world data, this is the first analysis comparing alpelisib combined with fulvestrant with standard treatments for HR+, HER2-, PIK3CA-mutant ABC in the post-CDK4/6i setting.

RESUMO

BACKGROUND: A reduction in renal angiomyolipoma volume observed with everolimus (EVE) treatment in patients with tuberous sclerosis complex (TSC) has been postulated to translate to clinical benefit by reducing the risk of renal hemorrhage and chronic renal failure. METHODS: The long-term effects of EVE on renal function (∼4 years of treatment) were examined in patients treated with EVE in the Phase 3 EXIST-1 and EXIST-2 studies. Patients in EXIST-1 had TSC and subependymal giant cell astrocytoma (SEGA), and patients in EXIST-2 had renal angiomyolipoma and a definite diagnosis of TSC or sporadic lymphangioleiomyomatosis. EVE was administered at 4.5 mg/m2/day, with adjustment to achieve target trough levels of 5-15 ng/mL in EXIST-1 and at 10 mg/day in EXIST-2. Estimated glomerular filtration rate (eGFR) and creatinine levels were assessed at baseline, at Weeks 2, 4, 6, 8, 12 and 18, then every 3 months thereafter. Proteinuria was graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. RESULTS: A total of 111 patients from EXIST-1 and 112 patients from EXIST-2 were included in this analysis. Respective mean ages at EVE initiation were 10.5 [standard deviation (SD) 6.45] and 33.2 (SD 10.29) years, and 3.6% and 37.5% of patients had undergone prior renal intervention. Mean baseline eGFR was 115 and 88 mL/min/1.73 m2 in EXIST-1 and EXIST-2, respectively. Overall, mean eGFR remained stable over time in both studies, with an decline in renal function mostly confined to some patients with severely compromised renal function before treatment. Patients with prior renal intervention exhibited low eGFR values throughout the study. The incidence of proteinuria increased after initiating treatment with EVE and was mostly Grade 1/2 in severity, with Grade 3 proteinuria reported in only two patients. Measurements of proteinuria were limited by the use of urine dipstick tests. CONCLUSIONS: The use of EVE does not appear to be nephrotoxic in patients with SEGA or renal angiomyolipoma associated with TSC and may preserve renal function in most patients.ClinicalTrials.gov identifiers NCT00789828 and NCT00790400.

RESUMO

In the phase III RADIANT-4 study, everolimus improved median progression-free survival (PFS) by 7.1 months in patients with advanced, progressive, well-differentiated (grade 1 or grade 2), non-functional lung or gastrointestinal neuroendocrine tumors (NETs) vs placebo (hazard ratio, 0.48; 95% confidence interval [CI], 0.35-0.67; P < .00001). This exploratory analysis reports the outcomes of the subgroup of patients with lung NETs. In RADIANT-4, patients were randomized (2:1) to everolimus 10 mg/d or placebo, both with best supportive care. This is a post hoc analysis of the lung subgroup with PFS, by central radiology review, as the primary endpoint; secondary endpoints included objective response rate and safety measures. Ninety of the 302 patients enrolled in the study had primary lung NET (everolimus, n = 63; placebo, n = 27). Median PFS (95% CI) by central review was 9.2 (6.8-10.9) months in the everolimus arm vs 3.6 (1.9-5.1) months in the placebo arm (hazard ratio, 0.50; 95% CI, 0.28-0.88). More patients who received everolimus (58%) experienced tumor shrinkage compared with placebo (13%). Most frequently reported (≥5% incidence) grade 3-4 drug-related adverse events (everolimus vs. placebo) included stomatitis (11% vs. 0%), hyperglycemia (10% vs. 0%), and any infections (8% vs. 0%). In patients with advanced, progressive, well-differentiated, non-functional lung NET, treatment with everolimus was associated with a median PFS improvement of 5.6 months, with a safety profile similar to that of the overall RADIANT-4 cohort. These results support the use of everolimus in patients with advanced, non-functional lung NET. The trial is registered with ClinicalTrials.gov (no. NCT01524783).

RESUMO

BACKGROUND: RECORD-4 assessed everolimus in patients with metastatic renal cell carcinoma (mRCC) who progressed after 1 prior anti-vascular endothelial growth factor (VEGF) or cytokine and reinforced the clinical benefit of second-line everolimus. Because of the high percentage of patients from China enrolled in RECORD-4 (41%) and some reported differences in responses to certain targeted agents between Chinese and Western patients, this subanalysis evaluated outcomes in Asian versus non-Asian patients. METHODS: RECORD-4 enrolled patients with clear cell mRCC into 3 cohorts based on prior first-line therapy: sunitinib, other anti-VEGF (sorafenib, bevacizumab, pazopanib, other), or cytokines. Patients received everolimus 10 mg/d until progression of disease (RECIST, v1.0) or intolerance. Primary end point was progression-free survival per investigator review. Data cutoff was Sept 1, 2014. RESULTS: Among Asian (n = 55) versus non-Asian (n = 79) patients, 98% versus 84% had good/intermediate MSKCC prognosis; 73% versus 65% were men, and 85% versus 73% were < 65 years of age. All (100%) Asian patients were of Chinese ethnicity. Median duration of exposure was 5.5 mo for Asian and 6.0 mo for non-Asian patients. Among Asian versus non-Asian patients, median progression-free survival (months) was 7.4 versus 7.8 overall, 7.4 versus 4.0 with prior sunitinib, and 5.7 versus 9.2 with prior other anti-VEGFs. Clinical benefit rate was similar between populations: 74.5% (95% CI 61.0-85.3) for Asian patients and 74.7% (95% CI 63.6-83.8) for non-Asian patients. Most patients achieved stable disease as best overall response (Asian, 63.6%; non-Asian, 69.6%). Overall rate of grade 3/4 adverse events appeared similar for Asian (58%) and non-Asian patients (54%). CONCLUSIONS: This RECORD-4 subanalysis demonstrated comparable efficacy and adverse event profiles of second-line everolimus in Asian and non-Asian patients. Efficacy and safety outcomes by prior therapy should be interpreted with caution because of small patient numbers in some subpopulations.

RESUMO

BACKGROUND: Patients with tuberous sclerosis complex (TSC) often have multiple TSC-associated hamartomas, particularly in the brain and kidney. METHODS: This was a post hoc analysis of pediatric patients being treated for subependymal giant cell astrocytomas (SEGAs) during the phase 3, randomized, double-blind, placebo-controlled EXIST-1 trial. Patients were initially randomly assigned to receive everolimus 4.5 mg/m2/day (target blood trough 5-15 mg/dl) or placebo and could continue in an open-label extension phase. Angiomyolipoma response rates were analyzed in patients aged <18 years with ≥1 target angiomyolipoma lesion at baseline. Response was defined as the proportion of patients with a ≥50% reduction in the sum volume of target renal angiomyolipomata from baseline, in the absence of new target angiomyolipomata, a >20% increase in kidney volume from nadir, and angiomyolipoma-related bleeding ≥ grade 2. Tolerability was also assessed. RESULTS: Overall, this analysis included 33 patients. Renal angiomyolipoma response was achieved by 75.8% of patients (95% confidence interval, 57.7-88.9%), with sustained mean reductions in renal angiomyolipoma volume over nearly 4 years of treatment. In addition, most (≥80%) achieved clinically relevant reductions in angiomyolipoma volume (≥50%), beginning at week 24 and continuing for the remainder of the study. Everolimus was generally well tolerated in this subgroup, with most adverse events being grade 1 or 2 in severity. CONCLUSIONS: Although everolimus is currently not indicated for this use, this analysis from EXIST-1 demonstrates its long-term efficacy and safety for the treatment of renal angiomyolipoma in pediatric patients undergoing treatment for TSC-associated SEGA.

RESUMO

BACKGROUND: The current exploratory analysis was performed to evaluate the efficacy and safety of everolimus for treatment of human epidermal growth factor receptor 2-positive (HER2+) advanced breast cancer in the Asian subset of patients in the BOLERO-1 trial. METHODS: Postmenopausal women with HER2+ advanced breast cancer, who had not received systemic therapy for advanced disease, were randomized 2:1 to receive everolimus or placebo, plus trastuzumab and paclitaxel. The two primary end points were investigator-assessed progression-free survival (PFS) in the full population and in the hormone receptor-negative (HR-) subpopulation. Secondary end points included assessment of the objective response rate, the clinical benefit rate, and safety. RESULTS: In the Asian subset, median PFS was similar in the everolimus (n = 198) and placebo (n = 105) arms in the full analysis set (hazard ratio = 0.82 (95% CI 0.61-1.11)). In the HR- subpopulation, everolimus prolonged median PFS by 10.97 months vs placebo (25.46 vs 14.49 months; hazard ratio = 0.48 (95% CI 0.29-0.79)). In the everolimus arm of the Asian subset, the most common adverse events of any grade were stomatitis (62.2%), diarrhea (48.0%), rash (43.4%) and neutropenia (42.3%). Neutropenia (grade 3: 27.6%; grade 4: 4.6%) and decreased neutrophil count (grade 3: 11.2%; grade 4: 3.6%) were the most frequent grade 3/4 adverse events. Serious adverse events included pneumonia (5.1%), pneumonitis (3.1%), and interstitial lung disease (3.1%). There were three deaths (1.5%) during treatment in the everolimus arm vs none in the placebo arm. CONCLUSIONS: The efficacy and safety of everolimus plus trastuzumab and paclitaxel as first-line treatment for HER2+ advanced breast cancer in the Asian subset was consistent with that reported previously in the overall population.

RESUMO

The TuberOus SClerosis registry to increase disease Awareness (TOSCA) Post-Authorization Safety Study (PASS) was a non-interventional, multicenter, safety substudy that assessed the long-term safety of everolimus in patients with tuberous sclerosis complex (TSC) receiving everolimus for its licensed indications in the European Union (EU). This substudy also aimed to address TSC-associated neuropsychiatric disorders (TAND), sexual development, and male infertility. Eligible patients were enrolled from 39 sites across 11 countries in the EU. Outcomes of interest included the incidence of adverse events (AEs), serious adverse events (SAEs), treatment-related AEs (TRAEs), AEs leading to everolimus discontinuation, AEs of special interest (AESIs), the observed relationship between everolimus blood levels and incidence of AESIs, TAND, and reproductive clinical features. Herein, we present the final analysis results from this substudy (data cutoff date: 22 January 2020). At data cutoff, 179 patients were enrolled (female, 59.2%; age ≥18 years, 65.9%), of which the majority completed the study (76%). Overall, 121 patients (67.6%) had AEs regardless of causality. The most frequent TRAEs (≥5%) were stomatitis (7.8%), aphthous ulcer (6.7%), and hypercholesterolemia (6.1%). The most common treatment-related SAEs (>1%) were pneumonia (3.4%), influenza, pyelonephritis, aphthous ulcer, stomatitis, dyslipidemia, and hypercholesterolemia (1.1% each). Ten patients (5.6%) reported AEs leading to everolimus discontinuation. The common psychiatric disorders (N = 179) were autism spectrum disorder (21.8%), anxiety disorder (12.8%), "other" psychiatric disorders (8.9%), attention-deficit hyperactivity disorder, and depressive disorder (7.8% each). Of 179 patients, 88 (49.2%) had ≥1 behavioral problem. Of these (n = 88), the most common (>20%) were sleep difficulties (47.7%), anxiety (43.2%), mood swings (37.5%), depression mood (35.2%), impulsivity (30.7%), severe aggression (23.9%), and overactivity (22.7%). Of 179 patients, four (2.2%) reported abnormal puberty onset, and three (1.7%) reported other reproductive disorders. Of 106 females, 23 (21.7%) reported menstrual cycle disorders and 10 (9.4%) reported amenorrhea. Available data did not show delays in sexual maturation or an association between sexual development and infertility. The results demonstrate that everolimus has a manageable long-term safety profile in the TSC treatment setting. No new safety signals emerged. This substudy also contributed to the mapping of TAND and reproductive clinical features in patients with TSC.

RESUMO

AIMS: We examined the prevalence of heavy episodic drinking in general practice attenders who were non-hazardous drinkers, the associated risk factors and the outcome over 6 months. METHODS: Consecutive attenders aged 18-75 were recruited from the UK, Spain, Slovenia, Estonia, the Netherlands and Portugal and followed up after 6 months. Data were collected on alcohol use using the Alcohol Use Disorder Identification test (at recruitment and 6 months) and risk factors for heavy episodic alcohol use at recruitment. RESULTS: The prevalence of heavy episodic drinking in non-hazardous drinkers was 4.5% across Europe [lowest in Portugal (1.5%); highest Netherlands (8.4%)]. It was less frequent in Spain, Slovenia, Estonia and Portugal compared with the UK and Netherlands. It was higher in men [odd ratio (OR) 4.4, 95% confidence interval (CI) 3.3, 5.9], people between 18 and 29 years of age, those employed (OR 1.8, 95% CI 1.3, 2.6) and those using recreational drugs (OR 2.1, 95% CI 1.4, 3.3). It was lower in people with existing DSMIV major depression (OR 0.54, 95% CI 0.31, 0.96). Heavy episodic drinkers were more likely to become hazardous drinkers at 6 months (male: OR 7.2, 95% CI 4.1, 12.7; female: OR 9.4, 95% CI 4.3, 20.6). CONCLUSION: Women and men in the UK, men in the Netherlands and younger people in all countries are at the greatest risk of exhibiting heavy episodic drinking behaviours even in the absence of hazardous alcohol use. There is hence an urgent need for general practitioners to consider early detection and management of heavy episodic drinking behaviour in this population.

RESUMO

PURPOSE: To evaluate the additive intraocular pressure-lowering effect of twice-daily brinzolamide 1%/brimonidine 0.2% fixed-dose combination (BBFC) as an adjunct to a prostaglandin analog (PGA) in patients with open-angle glaucoma or ocular hypertension insufficiently controlled with PGA monotherapy. METHODS: In this Phase 4, double-masked trial, patients aged ⩾18 years, with a mean intraocular pressure of ⩾19 and <32 mm Hg in at least one eye were randomized (1:1) to receive BBFC + PGA (n = 96) or vehicle + PGA (n = 92) for 6 weeks. The primary endpoint was the mean change in diurnal intraocular pressure from baseline (averaged over 09:00 and 11:00 h) at Week 6. RESULTS: The mean diurnal intraocular pressure at baseline was similar in the BBFC + PGA (22.8 mm Hg) and vehicle + PGA (22.9 mm Hg) groups. The least squares mean change in diurnal intraocular pressure from baseline at Week 6 was greater with BBFC + PGA (-5.59 mm Hg (95% confidence interval: -6.2 to -5.0)) than with vehicle + PGA (-2.15 mm Hg (95% confidence interval: -2.7 to -1.6)); the treatment difference was statistically significant in favor of BBFC + PGA (-3.44 mm Hg, (95% confidence interval: -4.2 to -2.7); p < 0.001). Ocular adverse events were reported in 21.1% and 8.7% of patients in the BBFC + PGA and vehicle + PGA groups, respectively. The most frequent ocular adverse event was ocular hyperemia (5.3%) in the BBFC + PGA group and blurred vision (2.2%) in the vehicle + PGA group. CONCLUSION: BBFC + PGA significantly reduced mean diurnal intraocular pressure than PGA alone in patients with open-angle glaucoma or ocular hypertension. The safety findings with BBFC + PGA were consistent with the known safety profile of the individual medications.

RESUMO

OBJECTIVE: The aim of the study was to assess the impact of systemic markers of inflammation on the outcomes in patients with neuroendocrine tumors (NETs) treated with everolimus or placebo (as measured by baseline neutrophil-to-lymphocyte ratio [NLR] and lymphocyte-to-monocyte ratio [LMR]). METHODS: Patient data (gastrointestinal, pancreatic, and lung NETs) from 2 large phase 3 studies, RADIANT-3 (n = 410) and RADIANT-4 (n = 302), were pooled and analyzed. The primary end point was centrally assessed progression-free survival (PFS) as estimated by the Kaplan-Meier method. RESULTS: In the pooled population, elevated LMR (median PFS, 11.1 months; 95% confidence interval, 9.3-13.7; hazard ratio, 0.69; P < 0.001) and reduced NLR (median PFS, 10.8 months; 95% confidence interval, 9.2-11.7; hazard ratio, 0.75; P = 0.0060) correlated with longer PFS among all patients. These markers were also found to be prognostic in the everolimus- and placebo-treated subgroups. CONCLUSIONS: Data from this study suggest that LMR and NLR are robust prognostic markers for NETs and could potentially be used to identify patients who may receive or are receiving the most benefit from targeted therapies. As both are derived from a complete blood count, they can be routinely used in clinical practice, providing valuable information to clinicians and patients alike.

RESUMO

PURPOSE: In the phase III SOLAR-1 trial (NCT02437318), the PI3Kα-selective inhibitor and degrader alpelisib significantly improved median progression-free survival when added to fulvestrant in patients with phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA)-mutated, hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer. We assessed health-related quality of life using patient-reported outcome measures in these patients. MATERIALS AND METHODS: In the PIK3CA-mutant cohort, 341 patients were randomly assigned 1:1 to receive alpelisib 300 mg daily or placebo plus fulvestrant 500 mg on days 1 and 15 of cycle 1 and on day 1 of subsequent 28-day cycles. Patient-reported outcomes were evaluated with the European Organisation for Research and Treatment of Cancer QoL of Cancer Patients and Brief Pain Inventory-Short Form questionnaires. Changes from baseline and time to 10% deterioration were analyzed using repeated measurement models and Cox models, respectively. RESULTS: Global Health Status/QoL and functional status were maintained from baseline (mean changes < 10 points) in the alpelisib (overall change from baseline [95% CI], -3.50 [-8.02 to 1.02]) and placebo arms (overall change from baseline [95% CI], 0.27 [-4.48 to 5.02]). Overall treatment effect in Global Health Status/QoL was not significantly different between arms (-3.77; 95% CI, -8.35 to 0.80; P = .101). Time to 10% deterioration for Global Health Status/QoL was similar between arms (hazard ratio, 1.03; 95% CI, 0.72 to 1.48). Compared with placebo, deterioration in social functioning and in diarrhea, appetite loss, nausea or vomiting, and fatigue symptom subscales occurred with alpelisib. Numerical improvement in Worst Pain was observed with alpelisib versus placebo (42% v 32%, week 24; P = .090). CONCLUSION: In SOLAR-1, there was no statistical difference in deterioration of Global Health Status/QoL between arms, whereas symptom subscales favored placebo for diarrhea, appetite loss, nausea or vomiting, and fatigue, known side effects of alpelisib. Treatment decisions must consider efficacy and tolerability; taken with clinical efficacy, these results support the benefit-risk profile of alpelisib in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative PIK3CA-mutated advanced breast cancer.

RESUMO

OBJECTIVES: To examine patterns of prescribing of oral antibiotics during pregnancy and to determine whether women were more or less likely to receive specific types of antibiotics in pregnancy than in the years before and after pregnancy. Finally, to identify socio-demographic factors associated with antibiotic prescribing in pregnancy. PATIENTS AND METHODS: We identified 114 999 women who gave live birth between 1992 and 2007 in The Health Improvement Network (THIN) UK primary care database. Antibiotic prescribing during pregnancy was estimated for each calendar year between 1992 and 2007. Self-controlled case series (SCCS) methodology was used to compare antibiotic prescribing during pregnancy with the years before and after pregnancy, and Poisson regression to examine association between demographic factors and antibiotic prescribing. RESULTS: A third of pregnant women received at least one antibiotic prescription during pregnancy. In each trimester, 14% of women received at least one antibiotic. Prescribing of antibiotics was lower in pregnancy than during a comparable period 1 year earlier [incidence rate ratio (IRR) 0.91 (95% CI 0.90-0.93)], but some antibiotics were prescribed more frequently in pregnancy: broad-spectrum penicillins [IRR 1.46 (1.42-1.49)]; cephalosporins [IRR 2.22 (2.13-2.31)]; and antibiotics for urinary tract infections [IRR 2.29 (2.01-2.61)]. Respiratory, urinary, skin and ear infections were the commonest indications. Urinary indications increased and respiratory, skin and ear infection indications declined during pregnancy, although a large proportion were prescribed without indication. Young age and social deprivation were associated with increased antibiotic prescribing during pregnancy. CONCLUSIONS: Antibiotic prescribing is widespread in pregnancy although marginally reduced compared with the year before pregnancy. There were substantial changes in types of antibiotics as well as in their indications during pregnancy. This may be explained by changes in threshold for treatment, diseases, detection and recording. Younger women and women from deprived areas were most likely to receive antibiotics in pregnancy.

RESUMO

PURPOSE: In the MONALEESA-3 Phase III trial of patients with hormone receptor-positive human epidermal growth factor receptor-negative advanced breast cancer, ribociclib plus fulvestrant significantly improved progression-free survival (PFS) and overall survival (OS). Here, we present patient-reported outcomes from the trial, including health-related quality of life (HRQOL). METHODS: Patients were randomized (2:1) to receive ribociclib plus fulvestrant or placebo plus fulvestrant. Time to definitive 10% deterioration (TTD) from baseline in HRQOL (global health status [GHS] from the EORTC QLQ-C30 questionnaire) and pain (BPI-SF questionnaire) were assessed using Kaplan-Meier estimates; a stratified Cox regression model was used to estimate the hazard ratio (HR) and 95% CIs. RESULTS: Deterioration ≥10% in the EORTC-QLQ-C30 GHS was observed in 33% of patients in the ribociclib group vs 34% of patients in the placebo (reference) group (HR for TTD ≥ 10% = 0.81 [95% CI, 0.62-1.1]). Similar findings were noted for TTD ≥5% (HR = 0.79 [95% CI, 0.61-1.0]) and TTD ≥15% (HR = 0.81 [95% CI, 0.60-1.08]). TTD ≥10% in emotional functioning (HR = 0.76 [95% CI, 0.57-1.01]) trended in favor of the ribociclib group, whereas results for fatigue and pain were similar between arms. TTD ≥10% in BPI-SF pain severity index score (HR = 0.77 [95% CI, 0.57-1.05]) and worst pain item score (HR = 0.81 [95% CI, 0.58-1.12]) trended in favor of ribociclib vs placebo. CONCLUSIONS: In addition to significantly prolonging PFS and OS compared with placebo plus fulvestrant, adding ribociclib to fulvestrant maintains HRQOL.

RESUMO

INTRODUCTION: Maximal medical therapy (MMT) is the use of ≥3 classes of topical anti-glaucoma agents to achieve maximal intraocular pressure (IOP) reduction while minimizing adverse effects and compliance challenges. PURPOSE: To evaluate the additive IOP-lowering effect of twice-daily brinzolamide 1%/brimonidine 0.2% fixed-dose combination (BBFC) used adjunctively with once daily travoprost 0.004%/timolol 0.5% fixed-dose combination (TTFC) in patients with open-angle glaucoma (OAG)/ocular hypertension (OHT). METHODS: In this phase IV, double-masked study, patients on TTFC for ≥28 days, aged ≥18 years, with mean IOP ≥19 and ≤28 mmHg in at least 1 eye were randomized to receive BBFC+TTFC (n=67) or vehicle+TTFC (n=67) for 6 weeks. The primary endpoint was mean change in diurnal IOP from baseline (BL, averaged over 09:00 and 11:00) at Week 6. RESULTS: The study was terminated prematurely due to recruitment challenges. BL mean IOP was similar in both groups (BBFC+TTFC: 21.6±1.78 mmHg; vehicle+TTFC: 21.8±1.90 mmHg). Mean change in diurnal IOP from BL at Week 6 was greater with BBFC+TTFC (-4.25 mmHg, 95% confidence interval [CI]: -4.7, -3.8) than with vehicle+TTFC (-2.11 mmHg, 95% CI: -2.6, -1.6, treatment difference, -2.15 mmHg (95% CI: -2.8, -1.5; P<0.001). Ocular adverse events (AEs) were reported in 11.9% of patients given BBFC+TTFC and 7.5% of patients given vehicle+TTFC. The AE with highest frequency was punctate keratitis (3%) in the BBFC+TTFC group; eye irritation (3%) in the vehicle+TTFC group. CONCLUSION: BBFC+TTFC as MMT demonstrated clinically relevant and statistically significant reductions in mean diurnal IOP in patients with OAG/OHT. AEs were consistent with known safety profiles of individual medications.
