RESUMO

PURPOSE: To assess the real-world prevalence of microsatellite instability (MSI)/mismatch repair (MMR) testing and related tumor status in recurrent/advanced endometrial cancer patients in Europe. METHODS: Data were from two multi-center, retrospective patient chart review studies conducted in the United Kingdom, Germany, Italy, France and Spain: The Endometrial Cancer Health Outcomes-Europe-First-Line (ECHO-EU-1L) study and the ECHO-EU-Second-Line (ECHO-EU-2L) study. ECHO-EU-1L included recurrent/advanced endometrial cancer patients who received first-line systemic therapy between 1/JUN/2016 and 31/MAR/2020 after recurrent/advanced diagnosis. ECHO-EU-2L included patients with recurrent/advanced endometrial cancer who progressed between 1/JUN/2016 and 30/JUN/2019 following prior first-line systemic therapy. Data collected included patient demographics, MSI/MMR tumor testing and results, and clinical/treatment characteristics. RESULTS: ECHO-EU-1L included 242 first-line patients and ECHO-EU-2L included 475 s-line patients. For all patients, median age at recurrent/advanced diagnosis was 69 years, roughly half had endometrioid carcinoma histology and over 75% had Stage IIIB-IV disease at initial diagnosis. The prevalence of MSI/MMR testing in the first-line and second-line cohorts was similar (36.4 and 34.9%, respectively). Among those tested, a majority had non-MSI-high/MMR proficient tumors (80.7 and 74.7% among first- and second-line patients, respectively). About 15% had MSI-high/MMR deficient tumors in both cohorts, and a few patients had discordant results (3.4 and 10.8% among first- and second-line patients, respectively). CONCLUSION: Prior to the approvals of biomarker-directed therapies for recurrent/advanced endometrial cancer patients in Europe, there were low MSI/MMR testing rates for these patients of just over one-third. Given the availability of biomarker-directed therapies, increased MSI/MMR testing may help inform treatment decisions for recurrent/advanced endometrial cancer patients in Europe.

RESUMO

OBJECTIVE: To evaluate real-world treatment patterns and clinical outcomes in recurrent/advanced endometrial cancer patients who progressed following prior systemic therapy in clinical practice in Europe. DESIGN: Endometrial Cancer Health Outcomes-Europe (ECHO-EU) is a retrospective patient chart review study. SETTING: ECHO-EU is a multicentre study conducted in the UK, Germany, Italy, France and Spain. PARTICIPANTS: Patients with recurrent/advanced endometrial cancer who progressed between 1 July 2016 and 30 June 2019 following prior first-line systemic therapy were eligible and data were collected until last available follow-up through November 2021. PRIMARY AND SECONDARY OUTCOME MEASURES: Data collected included patient demographics, clinical and treatment characteristics, and clinical outcomes. Kaplan-Meier analyses were performed since initiation of second-line therapy to estimate time to treatment discontinuation, real-world progression-free survival (rwPFS) and overall survival (OS). RESULTS: A total of 475 patients were included from EU5 countries. Median age was 69 years at advanced endometrial cancer diagnosis, 78.7% had stage IIIB-IV disease, 45.9% had Eastern Cooperative Oncology Group status ≥2 at second-line therapy initiation. In second line, a majority of patients initiated either non-platinum-based chemotherapy (55.6%) or endocrine therapy (16.2%). Physician-reported real-world overall response rate (classified as complete or partial response) to second-line therapy was 34.5%, median rwPFS was 7.4 months (95% CI 6.2 to 8.0) and median OS was 11.0 months (95% CI 9.9 to 12.3). CONCLUSIONS: Patients had poor clinical outcomes with a median OS of <1 year and rwPFS of approximately 7 months, highlighting the significant unmet medical need in pretreated recurrent/advanced endometrial cancer patients. Novel therapies with potential to improve PFS and OS over conventional therapies could provide significant clinical benefit.

RESUMO

PURPOSE: In 2010, the US Food and Drug Administration approved eribulin for the treatment of metastatic breast cancer (MBC). Since then, the treatment landscape has evolved with many new therapy classes, a more recent one being the small molecule inhibitors of phosphoinositide 3 kinase (PI3K). We sought to characterize the treatment patterns and clinical outcomes of patients with MBC who received eribulin following prior treatment with a PI3K inhibitor. METHODS: A retrospective cohort study based on medical record review included MBC patients who initiated eribulin between March 2019 and September 2020 following prior treatment with a PI3K inhibitor was conducted. Patient demographics, treatment characteristics, and clinical outcomes were analyzed descriptively. Real-world progression-free survival (rwPFS) and overall survival (OS) were estimated from the initiation of eribulin therapy using Kaplan-Meier analyses. RESULTS: 82 eligible patients were included. Patients' median age at eribulin initiation was 62 years; 86.5% had hormone receptor-positive, human epidermal growth factor receptor 2-negative tumors. Eribulin was most often administered in the second or third line (82.9%) in the metastatic setting. Best overall response on eribulin was reported as complete or partial response in 72% of the patients. The median rwPFS was 18.9 months (95% confidence interval [CI], 12.4-not estimable); median OS was not reached. The estimated rwPFS and OS rates at 12 months were 63.3% (95% CI, 50.5-73.7) and 82.6% (95% CI, 72.4-89.3), respectively. CONCLUSION: Our real-world study suggests that eribulin may be a potential treatment option for MBC patients who fail a prior PI3K inhibitor.

RESUMO

Aim: Describe treatment and dosing patterns of lenvatinib and pembrolizumab combination therapy (lenva+pembro) among endometrial cancer (EC) patients in US clinical practice. Materials & methods: Retrospective cohort study among adults with EC initiating lenva+pembro in second line (2L) or third line and later (≥3L) between 17 September 2019 and 30 June 2021. Results: 110 patients initiated lenva+pembro in 2L and 135 patients in ≥3L. Majority of patients initiated lenva+pembro at label-recommended starting doses/interval. Less than half changed lenvatinib dose over time. At median follow-up of 7.3 and 8.7 months, median (95% CI) duration of therapy was 5.1 (4.7-6.1) and 5.8 (4.2-7.3) months for patients in 2L and ≥3L, respectively. Conclusion: Lenva+pembro was mostly initiated at label-recommended dose.


This study looked at details of lenvatinib and pembrolizumab combination treatment among patients with endometrial cancer (EC) in the USA. Specifically, these patients had received prior chemotherapy or hormone therapy before starting lenvatinib and pembrolizumab. Most patients started lenvatinib and pembrolizumab at the dose recommended by the product label and received the next pembrolizumab injection within the recommended timeframe. Over time, more than half of the patients did not change the dose of lenvatinib, and most patients had the same dose of pembrolizumab. On average, patients were treated with lenvatinib and pembrolizumab for 5­6 months. This study showed that in general, patients were taking lenvatinib and pembrolizumab for treatment of EC as recommended by product labels.

RESUMO

PURPOSE: Lenvatinib was approved for the treatment of patients with radioiodine-refractory differentiated thyroid cancer (RAI-R DTC) in the United States (US) in 2015. The main objective of the current study was to assess real-world clinical effectiveness in RAI-R DTC patients treated with first line lenvatinib monotherapy in the US. METHODS: A retrospective chart review was conducted in RAI-R DTC patients who initiated lenvatinib monotherapy as first line treatment between February 2015 and September 2020. Anonymized data were abstracted by prescribing physicians from individual patient's electronic health records. Clinical outcomes included provider-reported real-world best overall response (rwBOR), real-world progression-free survival (rwPFS), and overall survival (OS). Time-to-event endpoints were assessed using Kaplan-Meier methods. RESULTS: Our study included 308 RAI-R DTC patients treated with first line lenvatinib. At lenvatinib initiation, patients' median age was 60 years, 51.6% were female, and 26.0% of patients had an ECOG performance score of ≥2. Over the follow-up period, 32.5% of patients discontinued first line lenvatinib permanently, with others remaining on treatment. The median duration of lenvatinib therapy was 17.5 months overall. Provider-reported rwBOR (complete or partial response) to lenvatinib was 72.4%. Median rwPFS was 49.0 months. Estimated rwPFS rates at 24 and 48 months were 68.5% and 55.0%, respectively. Estimated OS rates at 24 and 72 months were 78.4% and 57.0%, respectively; median OS was not reached. CONCLUSION: The current study reinforces the clinical effectiveness of first line lenvatinib as standard of care in patients with RAI-R DTC in real-world clinical practice in the US.

RESUMO

Introduction: Eribulin was approved by the FDA in 2010 for the treatment of metastatic breast cancer (MBC) in the United States (US). More recently, several immuno-oncology (IO) and antibody-drug conjugate (ADC) regimens have been approved for MBC. We assessed the treatment patterns and clinical outcomes in MBC patients treated with eribulin following treatment with an IO or ADC in US clinical practice. Materials and Methods: In a retrospective patient medical chart review study, patients with MBC, aged ≥18 years, who initiated eribulin therapy between March 1, 2019, and September 30, 2020, treated with either prior IO or ADC in the metastatic setting were included. Patient demographics, treatment characteristics, and clinical outcomes were analyzed descriptively. Real-world progression-free survival (rwPFS) and overall survival (OS) were estimated using Kaplan-Meier analyses. Results: In the study population (N=143), median age at eribulin initiation was 62 years; 64% were Caucasian, and 67% had triple-negative MBC (TNBC). Eribulin therapy was used in the second to fifth line of therapy in the metastatic setting; median treatment duration was 7.2 months. The overall response rate for eribulin was 59.4%. Median rwPFS and OS from eribulin initiation were 21.4 months (95% CI, 12.9-not estimable [NE]) and 24.2 months (95% CI, 17.5-NE), respectively. In patients with TNBC, median rwPFS and OS from eribulin initiation were 12.0 months (95% CI, 8.8-NE) and 18.3 months (95% CI, 14.9-NE), respectively. Conclusion: These real-world data provide evidence for the clinical effectiveness outcomes of eribulin treatment among MBC patients previously treated with an IO or ADC.

RESUMO

KRAS G12D mutation has been found in approximately 45% of pancreatic ductal adenocarcinoma (PDAC) cases, making it an attractive therapeutic target. Through structure-based drug design, a series of potent and selective KRAS G12D inhibitors were designed. The lead compound, ERAS-5024, inhibited ERK1/2 phosphorylation and cell proliferation in three-dimensional Cell-Titer Glo assays in AsPC-1 PDAC cells with single-digit nanomolar potency and caused tumor regression in the in vivo efficacy studies. We describe here the details of the design and synthesis program that led to the discovery of ERAS-5024.

RESUMO

Two potent and selective KRASG12D inhibitors, ERAS-4693 and ERAS-5024, were generated as possible clinical candidates to treat patients harboring G12D mutations in solid tumors. Both molecules exhibited strong anti-tumor activity in the KRASG12D mutant PDAC xenograft mouse models while ERAS-5024 also showed tumor growth inhibition when administered on an intermittent dosing regimen. Acute dose-limiting toxicity consistent with an allergic reaction was observed for both molecules shortly after administration at doses just above those which demonstrated anti-tumor activity, indicative of a narrow therapeutic index. A series of studies were subsequently conducted to identify a common underlying mechanism for the observed toxicity, including CETSA® (Cellular Thermal Shift Assay) as well as several functional off-target screens. Both ERAS-4693 and ERAS-5024 were identified to agonize MRGPRX2 which has been linked to pseudo-allergic reactions. In vivo toxicologic characterization of both molecules included repeat-dose studies in the rat and dog. Dose-limiting toxicities were observed in both species with ERAS-4693 and ERAS-5024 and plasma exposure levels at the maximum tolerated doses were generally below that which caused strong anti-tumor activity, supporting the initial observation of a narrow therapeutic index. Additional overlapping toxicities included a reduction in reticulocytes and clinical pathological changes suggestive of an inflammatory response. Furthermore, increases in plasma histamine were observed in dogs administered ERAS-5024, supporting the hypothesis that MRGPRX2 agonism may be the cause of the pseudo-allergic reaction. This work highlights the importance of balancing both the safety and efficacy of KRASG12D inhibitors as this class of molecules begins to enter clinical development.

RESUMO

Objective: Microsatellite instability (MSI) due to defective DNA mismatch repair has emerged as an actionable biomarker in advanced endometrial cancer (aEC). Currently, there are no treatment patterns and outcomes data in non-MSI-high (non-MSI-H) or mismatch repair proficient (pMMR) aEC patients following prior systemic therapy (FPST). Our goal was to describe real-world data in this population in the US in 2019 and prior years. Methods: Endometrial Cancer Health Outcomes (ECHO) is a retrospective patient chart review study conducted in the US. Patients with non-MSI-H/pMMR aEC and progression between 06/01/2016-06/30/2019 FPST were eligible. Data collected included patient demographics, clinical and treatment characteristics, and clinical outcomes. Kaplan-Meier analyses were performed to estimate time to treatment discontinuation, real-world progression-free survival (rwPFS), and overall survival (OS), separately by treatment category. Results: A total of 165 eligible patients initiated second-line therapy with chemotherapy ± bevacizumab (n = 140) or hormonal therapy (n = 25). Median age was 66.0 years at aEC diagnosis, 70.2% were Stage IIIB-IV, 40.0% had ECOG ≥ 2 at second-line therapy initiation. Median rwPFS was 5.0 months (95% CI: 4.0-6.0) for patients receiving chemotherapy ± bevacizumab and 5.5 months (95% CI: 3.0-29.0) for those receiving hormonal therapy. Median OS was 10.0 months (95% CI: 8.0-13.0) and 9.0 months (95% CI: 6.0-NA) in these groups, respectively. Conclusions: Non-MSI-H/pMMR patients who initiated second-line therapy with chemotherapy ± bevacizumab or hormonal therapy had poor clinical outcomes with a median survival less than 1 year and rwPFS less than 6 months. This was the first study to define the clinical unmet need in patients with non-MSI-H/pMMR aEC with conventional therapy.

RESUMO

OBJECTIVE: To evaluate whether early Psoriasis Area Severity Index (PASI) improvements can predict week 28 tildrakizumab responders and nonresponders. METHODS: Psoriasis patients pooled from two tildrakizumab phase 3 trials randomized to receive tildrakizumab 100 mg at weeks 0, 4, 16, and 28 were included. Patients were grouped by week 28 PASI responses (<50, 50-74, 75-89, and 90-100). PASI improvements from baseline at weeks 4 and 16 were analyzed for each response group. RESULTS: Of 575 patients included, 8.3%, 14.3%, 23.8%, and 53.6%, respectively, achieved PASI <50, 50-74, 75-89, and 90-100 at week 28. Of patients with PASI <50 at week 16, 85% did not achieve PASI ≥75 at week 28 (nonresponders). Rapid response, defined as PASI ≥50 at week 4 (after a single tildrakizumab dose), was observed in 41% of patients. Of these patients, 87% were week 28 responders (PASI ≥75); 67% were 'super responders' (PASI 90-100). Among week 28 responders and super responders, 45% and 50% achieved PASI ≥50 at week 4, respectively. CONCLUSIONS: Tildrakizumab week 28 nonresponders can be identified by week 16 PASI response. PASI improvements as early as week 4 can predict patients' week 28 PASI improvement status.

RESUMO

PURPOSE: Real-world treatment patterns among psoriasis patients with and without psoriatic arthritis (PsA) newly initiating treatment with a biologic or apremilast were assessed. PATIENTS AND METHODS: MarketScan claims data from adults with psoriasis and ?1 new prescription for secukinumab, adalimumab, ustekinumab, etanercept, or apremilast from January 1, 2015, to August 31, 2018, were assessed for adherence, switching, and combination therapy by index medication and PsA diagnosis. RESULTS: At treatment initiation, 22.0%-45.7% of patients had PsA. Over 24 months, discontinuation rates were high (34.4%-54.6%) overall and higher in patients with versus without PsA (all P<0.05 except secukinumab). Adherence was poor (16.8%-34.8%); switching and combination therapy were common. CONCLUSION: Treatment patterns varied, with better outcomes in PsA patients receiving anti-tumor necrosis factor versus anti-IL17/IL12/23 agents.

RESUMO

The optical fiber curvature sensor is an important device that is widely used in the field of medical instruments. In this paper, we proposed a high sensitivity curvature sensor based on a long period fiber grating (LPFG), which is inscribed in the two-mode fiber (TMF) by CO2 laser pulses. Unlike the traditional LPFG in the single-mode fiber, TMF-LPFG couples the high-order mode LP11 in the core with the modes in the cladding. From the experiment results, the wavelength shifts to the short-wave direction as the sensor bends. This sensor offers a high curvature sensitivity of -23.67nm/m-1 in the range of 1.137-4.684m-1 and -18.95nm/m-1 in the range of 4.766-6.132m-1, respectively. Moreover, this sensor has the advantage of low transmission loss, which is less than -4dB.

RESUMO

Plaque psoriasis is a chronic disease requiring long-term therapy. However, long-term real-world treatment patterns and costs are not well characterized. This study examined treatment patterns and healthcare costs among patients newly initiating a biologic or apremilast for moderate-to-severe plaque psoriasis. Included patients had ?1 prescription for secukinumab, ixekizumab, adalimumab, ustekinumab, etanercept, or apremilast between 01/01/2015 and 08/31/2018, no prior use of the index medication, and continuous enrolment 12 months pre-index and 24 months post-index. Treatment adherence, non-persistence, discontinuation, switching, use of combination therapy, and re-initiation were assessed at 12, 18, and 24 -months post-index. In addition, total and psoriasis-related healthcare costs were evaluated at 24 months. A total of 7,773 patients with 24-month follow-up were included. Overall, adherence was low (21.3%-33.5%) and non-persistence was high (58.4%-86.5%) over 24 months. Discontinuation (38.4%-51.3%), switching (29.7%-52.6%), combination therapy (27.6%-42.9%), and re-initiation of the index medication (19.3%-44.5%) were common. Healthcare costs were high and mostly contributed by psoriasis treatment. Therefore, maintaining disease control on long-term therapy is still challenging for many patients.

RESUMO

INTRODUCTION: Eribulin was approved in the United States (US) in 2010 for patients with metastatic breast cancer (MBC) who previously received at least two chemotherapeutic regimens, including anthracycline and taxane in the adjuvant or metastatic setting. With significant changes to the treatment landscape over the past decade, assessment of the real-world effectiveness of eribulin in clinical practice when used according to the approved US indication is valuable. METHODS: Patients with MBC were identified by community oncologists through a retrospective, multi-site patient chart review; de-identified data were abstracted into electronic case report forms. Eligible patients initiated eribulin consistent with approved US indication between 1 January 2011 and 31 December 2017. Clinical outcomes assessed included objective response rate (ORR), progression-free survival (PFS) and overall survival (OS) in all patients and those with triple negative breast cancer (TNBC). RESULTS: The analysis included 513 patients (median 59.0 years; 38.8% with Eastern Cooperative Oncology Group status ≥ 2). Eribulin was third-line therapy for 78.0% of patients, and fourth-line or later for the remainder. ORR was 54.4%, median PFS was 6.1 months (95% CI: 5.8, 6.6), and median OS was 10.6 months (95% CI 9.9, 11.7) in all patients. Among the 49.9% of patients with TNBC, ORR was 55.1%, median PFS was 5.8 months (95% CI 5.1, 6.4), and median OS was 9.8 months (95% CI 8.6, 11.0). CONCLUSION: The current retrospective chart review study reinforces the clinical effectiveness of eribulin in patients with MBC, including those with TNBC, when used according to the approved US indication in real-world clinical practice.

RESUMO

OBJECTIVES: To compare treatment patterns and costs among psoriasis patients with and without metabolic conditions newly initiating a biologic or apremilast. METHODS: Adult patients included had ≥1 prescription for secukinumab, adalimumab, ustekinumab, etanercept, or apremilast between 01/01/2015 and 08/31/2018 (date of first prescription was index date) and no index drug use in the 12-months pre-index, and continuous enrollment in the 12-month pre-index and 24-month post-index periods. Patients were divided into mutually exclusive treatment cohorts and stratified by their pre-index metabolic condition status. Treatment patterns (adherence, non-persistence, switching, discontinuation, use of combination therapy, and re-initiation) and healthcare costs were compared. RESULTS: Overall, 7773 patients were included; 47.5-56.7% had a metabolic condition. Except for the apremilast group, patients with metabolic conditions had higher discontinuation (secukinumab: 50.6% vs. 43.7%; adalimumab*: 53.9% vs. 48.7%; ustekinumab*: 41.9% vs. 35.1%; etanercept: 42.8% vs. 41.2%; apremilast: 43.1% vs. 46.1%) and switching (secukinumab: 48.1% vs. 41.2%; adalimumab*: 47.8% vs. 41.9%; ustekinumab*: 34.5% vs. 25.3%; etanercept*: 53.6% vs. 51.5%; apremilast: 45.8% vs. 44.6%) than patients without (*p < .05). Patients with metabolic conditions incurred significantly higher costs. CONCLUSION: Many psoriasis patients initiating biologics or apremilast had metabolic conditions. These patients had higher discontinuation and switching, and significantly higher healthcare costs.

RESUMO

A heatsink is a large experimental device which is used to simulate the outer space environment. In this paper, a Raman-based distributed temperature sensor was used for real-time and continuous heatsink temperature monitoring, and a special Raman-based distributed temperature sensing method and system have been proposed. This method takes advantage of three calibration parameters ( Δ α , γ , C ) to calculate the temperature. These three parameters are related to the attenuation of the optical fiber, the Raman translation, and the difference of optoelectronic conversion, respectively. Optical time domain reflectometry was used to calculate the location. A series of heatsink temperature measurement experiments were performed in a vacuum and -173 °C environment. When the temperature dropped to -100 °C, the parameter Δ α was found to vary. A method was proposed to recalculate Δ α and modify the traditional Raman fiber temperature equation. The results of the experiments confirmed the validity of this modified Raman fiber temperature equation. Based on this modified equation, the temperature field in the heatsink was calculated. The Raman-based distributed temperature sensor has potential applications in temperature measurement and judging the occurrence of faults in space exploration.

RESUMO

Assessing target occupancy is critical for establishing proof-of-mechanism for novel inhibitors and to determine whether robust target inhibition can be achieved at tolerated doses. This is challenging in the clinic using conventional methods due to the need for untreated controls. We describe a new mass spectrometry approach to quantitatively assess target occupancy for covalent inhibitors that does not require untreated controls, and apply the method to the KRASG12C inhibitor ARS-1620.

RESUMO

The highly enantioselective totally N-selective hydroxyamination reaction of α-aryl-α-cyanoacetates with 2-nitrosopyridines was realized by using a chiral N,N'-dioxide/Mg(OTf)2 complex as catalyst, which enriches the nitroso chemistry. A variety of 2-cyano-2-[hydroxyl(pyrydin-2-yl)amino]acetates with quaternary stereocenters and potential antibacterial activities were obtained in excellent yields with good to excellent ee values under as low as 0.05 mol % catalyst loading. The products could be easily transformed to useful α-amino amides and 1,2-diamines. Besides, a possible transition state model was proposed to elucidate the origin of the chirality induction.
