Lenvatinib plus pembrolizumab in the patients with advanced previously treated endometrial cancer: A cost-effectiveness analysis in the United States and in China.

To investigate the cost-effectiveness of lenvatinib plus pembrolizumab (LP) compared to chemotherapy as a second-line treatment for advanced endometrial cancer (EC) from the United States and Chinese payers' perspective. In this economic evaluation, a partitioned survival model was constructed from the perspective of the United States and Chinese payers. The survival data were derived from the clinical trial (309-KEYNOTE-775), while costs and utility values were sourced from databases and published literature. Total costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER) were estimated. The robustness of the model was evaluated through sensitivity analyses, and price adjustment scenario analyses was also performed. Base-case analysis indicated that LP wouldn't be cost-effective in the United States at the WTP threshold of $200 000, with improved effectiveness of 0.75 QALYs and an additional cost of $398596.81 (ICER $531392.20). While LP was cost-effective in China, with improved effectiveness of 0.75 QALYs and an increased overall cost of $62270.44 (ICER $83016.29). Sensitivity analyses revealed that the above results were stable. The scenario analyses results indicated that LP was cost-effective in the United States when the prices of lenvatinib and pembrolizumab were simultaneously reduced by 61.95% ($26.5361/mg for lenvatinib and $19.1532/mg for pembrolizumab). LP isn't cost-effective in the patients with advanced previously treated endometrial cancer in the United States, whereas it is cost-effective in China. The evidence-based pricing strategy provided by this study could benefit decision-makers in making optimal decisions and clinicians in general clinical practice. More evidence about budget impact and affordability for patients is needed.

Liquid biopsy as a new era in endometrial cancer

Abstract Endometrial cancer (EC) is one of the most frequent invasive cancers of the female genital tract, and despite the rising incidence of EC worldwide and the poor overall survival of patients, no viable blood-based biomarker exists to detect and track EC recurrence during routine follow-up. Identification of new genetic targets and biomarkers linked to enhanced recurrence risk and medication response is a primary clinical issue in the treatment of advanced endometrial cancer. In this regard, liquid biopsy has become a breakthrough in human cancers. A liquid biopsy blood test has the advantage of being more sensitive than traditional imaging and is a minimally invasive complement to needle or excision biopsies of tissue. Here in this article, we discussed the advances and limitations of liquid biopsy. The detection of biomarkers and variations in liquid biopsy may help the diagnostic process of endometrial cancer cases.

Combination of pembrolizumab and lenvatinib in second-line therapy for MSS/pMMR advanced endometrial cancer: literature review and a case report

Despite the existing standard treatments for endometrial cancer, the prognosis for these patients remained poor until recently. None of currently available cytostatics ensured long-term disease control and long-term survival of patients receiving standard platinum-based therapy. Poor treatment outcomes in patients with advanced endometrial cancer necessitated changes in therapeutic approaches and development of more effective treatment regimens. Better understanding of carcinogenesis mechanisms, emergence of a new molecular classification of endometrial cancer, and implementation of tailored treatment approaches based on tumor types led to a significant breakthrough in the treatment of advanced endometrial cancer. Currently, the most effective second-line therapy for endometrial cancer with high level microsatellite instability (MSI-h) or deficient mismatch repair system (dMMR) (25 % of cases), and no indications for surgery is pembrolizumab monotherapy. Most of cancers (about 75 %) are represented by microsatellite-stable and mismatch repair proficient tumors (MSS/рMMR). Patients with such tumors demonstrating disease progression after systemic therapy should receive a combinations of the immune checkpoint inhibitor pembrolizumab and the multi-targeted tyrosine kinase inhibitor lenvatinib. In this article, we review relevant literature and report a case of successful treatment of MSS/pMMR advanced endometrial cancer with a combination of pembrolizumab and lenvatinib as a second-line therapy (after disease progression in response to platinum-containing first-line chemotherapy), which ensured long-term disease control.

Fanconi anemia complementation group D2 promotes sensitivity of endometrial cancer cells to chemotherapeutic agents by inhibiting the ferroptosis pathway

BackgroundResistance can develop during treatment of advanced endometrial cancer (EC), leading to unsatisfactory results. Fanconi anemia complementation group D2 (Fancd2) has been shown to be closely related to drug resistance in cancer cells. Therefore, this study was designed to explore the correlation of Fancd2 with EC resistance and the mechanism of Fancd2.MethodsReal-time quantitative PCR (RT-qPCR) was used to detect the expression of Fancd2 in EC tissues and cells. EC cells (Ishikawa) and paclitaxel-resistant EC cells (Ishikawa/TAX) were transfected to knock down Fancd2. In addition, the ferroptosis inhibitor Ferrostatin-1 was adopted to treat Ishikawa/TAX cells. The sensitivity of cancer cells to chemotherapeutic agents was observed via 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, and inhibitory concentration (IC)50 was calculated. Reactive oxygen species (ROS) levels were measured by flow cytometry, the activity of malondialdehyde (MDA) and the levels of glutathione (GSH) and Fe2+ in cells were detected by corresponding kits, and protein expression of solute farrier family 7 member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4) was obtained through western blot.ResultsCompared with the normal tissues and endometrial epithelial cells, Fancd2 expression was significantly increased in EC tissues and Ishikawa cells, respectively. After knock-down of Fancd2, Ishikawa cells showed significantly increased sensitivity to chemotherapeutic agents. Besides, compared with Ishikawa cells, the levels of ROS, the activity of MDA, and the levels of GSH and Fe2+ were significantly decreased in Ishikawa/TAX cells, while the expression levels of SLC7A11 and GPX4 were significantly increased. Knock-down of Fancd2 significantly increased the ferroptosis levels in Ishikawa/TAX cells, but this effect could be reversed by Ferrostatin-1.ConclusionFancd2 increases drug resistance in EC cells by inhibiting the cellular ferroptosis pathway.

Complete radiological response when using pembrolizumab in the mono mode in the 2nd-line drug therapy of MSI-h / dMMR-positive advanced endometrial cancer. A clinical case

Until recently, the prognosis of patients with advanced endometrial cancer remained disappointing despite the standard treatment methods. None of the drugs in the arsenal of oncologists-chemotherapists provided long-term disease control and long-term survival of patients who received standard platinum-containing first-line chemotherapy. It is obvious that the poor results of treatment in patients with advanced endometrial cancer required a change in treatment approaches and indicated the need to develop more effective treatment regimens. A deeper understanding of the mechanisms of carcinogenesis, the emergence of new molecular classification of endometrial cancer and division of treatment approaches depending on the tumor biological potential has led to significant breakthrough in the treatment of advanced endometrial cancer. One of the most significant achievements is discovery of the function of microsatellite instability (MSI) and disorders in the repair system of unpaired bases of deoxyribonucleic acid (MMR) as a predictor of high efficient immunotherapy – a new direction of systemic drug therapy for the advanced endometrial cancer. The paper presents a clinical case of successful treatment of MSI-h / dMMR-positive advanced endometrial cancer using pembrolizumab as a second-line therapy (in the presence of refractoriness to standard platinum-based chemotherapy of the 1st line) in a mono mode with a complete radiological response of the tumor to treatment.

Cost-effectiveness analysis of dostarlimab plus carboplatin-paclitaxel as first-line treatment for advanced endometrial cancer.

A recent phase III clinical trial (NCT03981796) evaluated the efficacy and safety of dostarlimab combined with carboplatin-paclitaxel (DOS-CP) compared to placebo combined with carboplatin-paclitaxel (PLB-CP) as a first-line treatment for advanced endometrial cancer (EC). The NCT03981796 trial demonstrated that DOS-CP significantly improved progression-free survival and overall survival of patients with advanced EC while maintaining an acceptable safety profile. However, DOS-CP is expensive and its cost-effectiveness has not been evaluated. This study aims to evaluate the cost-effectiveness of DOS-CP compared to PLB-CP as a first-line treatment for advanced EC from the perspective of the Chinese healthcare system. A Markov model with three health states was developed to evaluate the cost-effectiveness of DOS-CP as a first-line treatment for advanced EC. Clinical efficacy data were derived from the NCT03981796 trial, and drug costs were determined based on national tender prices. Other costs and utility values were obtained from published literature. The outcomes assessed included total costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs). The robustness of the model was assessed through one-way sensitivity analysis and probabilistic sensitivity analysis. In comparison to PLB-CP, the ICER of DOS-CP was $98,276.61/QALY for the overall population, $53,063.61/QALY for the dMMR subgroup, and $124,088.56/QALY for the pMMR subgroup. All of these ICER values were higher than the willingness-to-pay threshold of $38,201 per QALY. The most important variable that affected the results of the model was the discount rate, the cost of dostarlimab, and the utility value for progressive disease. From the perspective of the Chinese healthcare system, DOS-CP is unlikely to be a cost-effective first-line treatment option for advanced EC.

Can Immunotherapy Replace Radiation in Locally Advanced Endometrial Cancer?: Treatment for Advanced Endometrial Cancer

Can Immunotherapy Replace Radiation in Locally Advanced Endometrial Cancer?: Treatment for Advanced Endometrial Cancer

A randomized phase II study comparing single-agent olaparib, single-agent cediranib, and the combinations of cediranib/olaparib, olaparib/durvalumab (MEDI4736), cediranib/durvalumab (MEDI4736), and olaparib/AZD5363 (capivasertib) in women with recurrent, persistent, or metastatic endometrial cancer.

TPS5629 Background: Identifying new approaches for the treatment of advanced endometrial cancer (EC) is a priority. A platform study design allows for a faster investigation of novel drug combinations. NRG-GY012 is an ongoing platform study investigating drug combinations with the PARP inhibitor olaparib (O) and the anti-angiogenic agent cediranib (C). Results from the first set of arms established improved PFS for combination cediranib/olaparib over C alone, but did not meet its prespecified statistical significance. In this second set of arms, based on preclinical data, we are investigating the combination of O with an AKT inhibitor (capivasertib), O with durvalumab and C with durvalumab compared to the reference arm of C alone. Methods: This is a multicenter randomized four arm study for patients with recurrent, metastatic or persistent EC. Patients are randomized 1:1:1:1 to cediranib PO 30 mg Daily; olaparib 300 mg PO BID and capivasertib 400mg 4 day on/3 off schedule; olaparib 300 mg PO BID and durvalumab 1500mg q28 days; or the combination of cediranib 20 mg PO Daily 5 days on/2 days and durvalumab 1500mg q28. All treatment cycles are 28 days. Primary endpoint is progression free survival (PFS). The study is powered to detect a doubling in median PFS from 3.6 (based on cediranib alone) to 7.2 months with 90% power, using a one-sided test with α = 0.05 per comparison. Forty patients will be enrolled per arm, with an interim futility analysis planned at 50% information time. Eligibility includes endometroid, serous, and mixed histology EC; at least 1 prior line of chemotherapy (no more than 2 lines for metastatic disease), prior endocrine or immunotherapy alone is allowed; prior treatment with lenvatinib and pembrolizumab is excluded. Archival tumor tissue and blood samples are being collected for translational studies. The study is open across the NRG network; 76 of a planned 168 patients are enrolled to date. Safety analysis at the time of 36 patients enrolled did not demonstrate any new safety signals and the study was approved to continue enrollment. Clinical trial information: NCT03660826 .

Targeted Treatment of Advanced Endometrial Cancer: Focus on Pembrolizumab.

Endometrial cancer (EC) accounts for 2% of all new cancers. Advanced forms have a poor prognosis with barely 17% 5-year survival. The last few years improved our knowledge of EC with a new molecular classification derived from The Cancer Genome Atlas (TCGA). They are now divided between POLE mutant, Microsatellite Instability High (MSI-H) or deficient in Mismatch Repair System (dMMR), TP53 mutant and no specific molecular profile. Until now, treatments for advanced EC have included conventional platinum-based chemotherapy or hormonotherapy. The revolution in oncology represented by the advent of immune checkpoints inhibitors (ICI) has also led to a major advance in the management of recurrent and metastatic EC. Pembrolizumab, a well-known anti PD-1, has firstly been approved as monotherapy in the second-line setting for dMMR/MSI-H advanced EC. More recently, a combination of lenvatinib with pembrolizumab offered a new effective option in the second line setting irrespectively of the MMR status, giving a new opportunity for these patients who had no actual standard of care before. This combination is currently being evaluated as frontline therapy. Despite exciting results, the main problem in identifying solid biomarkers remains unresolved and further investigations are required. New original combinations of pembrolizumab with other drugs including chemotherapy, poly ADPribose polymerase inhibitors (PARP-i) or tyrosine kinase inhibitors are being tested and promise exciting new therapeutic evolutions in a close future.

Mismatch repair deficiency, next-generation sequencing-based microsatellite instability, and tumor mutational burden as predictive biomarkers for immune checkpoint inhibitor effectiveness in frontline treatment of advanced stage endometrial cancer

Endometrial cancer: news from ASCO

SummaryAt ASCO 2022 important abstracts were presented. The programmed death1 (PD1) inhibitor dostarlimab was investigated in the phase III GARNET study in advanced or metastatic endometrial cancer after failure of previous platinum-based combination chemotherapy. In the first group of patients with tumors with dMMR (mismatch repair-deficiency) or MSI‑H (microsatellite-high; group A), the median progression-free survival (PFS) was significantly higher than in the group with pMMR (mismatch repair-proficiency) or those with MSS (microsatellite-stable) tumors (group B), i.e., 6.0 months in group A and 2.7 months in group B. Overall survival was > 50 months and 17 months, respectively. Immunotherapy-related adverse events were seen in 23% of patients, including grade 3 or 4 events in 8% of women. In all, 9% of patients discontinued treatment due to adverse events. Another important regimen is the combination of lenvatinib and pembrolizumab. In a randomized study of lenvatinib + pembrolizumab versus monotherapy with doxorubicin or paclitaxel in the second-line therapy of metastatic endometrial cancer, the chemotherapy-free regimen was superior. PFS2 was significantly higher in patients in the pMMR group and the all comer group if they received lenvatinib and pembrolizumab, compared to those receiving standard chemotherapy (p < 0.0001). In conclusion, checkpoint inhibitors ± lenvatinib are now established in the second-line treatment of advanced endometrial cancer. Overall, the inclusion of PD1 or PDL1 inhibitors in systemic treatment regimens offers a significant opportunity for patients whose treatment options in the past only included conventional chemotherapy, radiotherapy or hormonal therapy.

Complete resection after pembrolizumab treatment followed by salvage surgery in stage IVB endometrial cancer: A case report.

IntroductionThere is little evidence regarding the treatment of stage IVB endometrial cancer. Therefore, chemotherapy is more likely to be chosen as the initial and first-line treatment. Pembrolizumab is a new treatment choice for unresectable endometrial cancer after first-line chemotherapy failure.Presentation of caseHerein, we report the case of a 56-year-old patient diagnosed with stage IVB endometrial cancer. After eight cycles of first-line chemotherapy, computed tomography (CT) revealed relapse with re-enlargement of the para-aortic lymph nodes. Since the primary tumour had high microsatellite instability, we switched to pembrolizumab treatment. Pembrolizumab was effective but could not be continued due to adverse events after 10 cycles. Positron emission tomography-CT revealed active cancer in the uterus and para-aortic lymph nodes.DiscussionSince pembrolizumab treatment had to be discontinued, we performed salvage surgery, which achieved complete tumour removal, and the patient has had no evidence of disease for 16 months.ConclusionThis is the first case of complete surgical resection after administering pembrolizumab as a second-line treatment for advanced endometrial cancer.

Dostarlimab for the treatment of advanced endometrial cancer

ABSTRACT Introduction Between 20% and 30% of the endometrial cancers (EC) are associated with a deficiency of a mismatch repair (MMRd) protein or high microsatellite instability (MSI-H), characteristics that render the tumor more sensitive to immune checkpoint inhibitors. There is no standard treatment for advanced EC after progression to a platinum-containing regimen. Areas covered The phase I GARNET clinical trial assessed the safety, tolerability, and antitumor activity of anti-PD1 dostarlimab in patients with advanced solid tumors. The A1 cohort of this trial enrolled patients with MMRd or MSI-H recurrent or advanced EC who had previously received a platinum-containing regimen. The results of this cohort showed significant clinical activity, durable responses, and a favorable safety profile, without reducing quality of life. Based on these data, dostarlimab achieved accelerated approval. Expert opinion Although a randomized study has not yet been conducted, dostarlimab monotherapy should be the treatment of choice for patients with advanced MMRd EC in progression after a platinum-containing regimen. Selecting patients with EC for immune checkpoint inhibitors using the MMRd predictive biomarker could facilitate more efficient and sustainable health systems and avoid the use of more toxic combinations, leading to personalized medicine.

Risk and distribution of venous thromboembolic events during treatment for advanced endometrial cancer.

e17565 Background: Understanding the incidence and timing of venous thromboembolic (VTE) events among patients receiving treatment for advanced endometrial cancer (EC) may help to inform VTE risk stratification and consideration of thromboprophylaxis. We aimed to describe the rate of VTE at each stage of primary treatment for advanced EC as well as the baseline Khorana Score (KS) distribution in this population. Methods: This was a retrospective cohort study of patients diagnosed with stage IVB EC from January 2001 to July 2020 at a single academic institution. The primary outcome was VTE incidence at each stage of primary treatment (at diagnosis, during neoadjuvant chemotherapy [NACT] if applicable, post-operatively [< 30 days from surgery], or during adjuvant chemotherapy). Subjects who were anticoagulated at EC diagnosis were excluded. Khorana score was calculated according to established parameters (1 point each for gynecologic malignancy, pre-chemotherapy platelet count ≥ 350, hemoglobin < 10 or use of red blood cell growth factors, leukocyte count >11, and BMI ≥ 35). Descriptive statistics were used for analysis. Results: There were 76 patients diagnosed with stage IVB EC, 2 of whom were excluded for anticoagulation at cancer diagnosis. Of the remaining 74 patients, 58 underwent primary surgery (78%) and 16 received NACT (22%). A total of 59 received adjuvant chemotherapy after either primary or interval debulking surgery. The two predominant tumor histologies were serous (48%) and endometrioid (20%).A total of 16 VTE occurred during the primary treatment course (22%), 11 among the cohort receiving primary surgery (19%) and 5 among the cohort receiving NACT (31%). The distribution of VTE by stage of primary treatment is shown in Table. The rate of VTE was highest during adjuvant chemotherapy. There were 62 patients for whom a Khorana score could be calculated either before NACT or adjuvant chemotherapy. The distribution of KS was: 17 (27%) with KS 1 (low risk) and 45 (73%) with KS ≥ 2 (intermediate – high risk). Of the 11 non-postoperative VTE, 3 patients (27%) had KS 1 and 8 (73%) had KS ≥ 2. Conclusions: The incidence of VTE among patients with advanced EC was high regardless of whether treatment was initiated with NACT or primary surgery. The majority of VTE occurred among patients with a high KS, but those with a low KS remained at risk. Thromboprophylaxis among all patients with advanced EC may be warranted, and larger studies are needed to determine the performance of KS as a VTE predictor in advanced EC.[Table: see text]

Bevacizumab in advanced endometrial cancer

ObjectiveProspective data have demonstrated the efficacy of bevacizumab monotherapy in the treatment of advanced endometrial cancer. Bevacizumab is used off-label, and real-world data regarding the role of bevacizumab in endometrial cancer treatment are scant. In this largest single-institution retrospective study of its kind, we report our experience with bevacizumab monotherapy in the treatment of advanced/recurrent endometrial cancer. MethodsAll eligible patients (n = 101) had histologically confirmed endometrial cancer and were treated with bevacizumab at our institution from 2004 to 2017. Demographic data and tumor characteristics were obtained through chart review. Primary objective was response to therapy determined by Response Evaluation Criteria in Solid Tumors (RECIST v1.1). ResultsAnalysis included 13 grade 1/2 endometrioid, 15 grade 3 endometrioid, 44 serous, 8 carcinosarcoma, and 21 other/mixed histologies. No patients achieved complete (CR) or partial (PR) responses; 19 achieved stable disease (SD). The clinical benefit rate (CBR; CR + PR + SD) was 19% (95% CI: 12–28%). The CBRs were 7%, 17%, 21%, and 23% for patients with 1, 2, 3, and ≥ 4 prior treatment lines. Median PFS ranged from 2.6 months (2 lines) to 4.9 months (≥4 lines). The 3-year OS rate was 58% (95% CI: 47–67%). The median OS was 3.4 years (95% CI: 2.9–4.2), ranging from 2.5 years (2 lines) to 4.5 years (≥4 lines). The most common treatment-related adverse event was hypertension; 35 (78%) of 45 were grade 1 or 2. ConclusionsIn heavily pretreated advanced endometrial cancer, bevacizumab was associated with modest clinical efficacy and remains a viable palliative option in this setting.

COMBINATION OF LENVATINIB AND PEMBROLISUMAB IN THE TREATMENT OF ADVANCED ENDOMETRIAL CANCER: A CASE REPORT

Background. Endometrial cancer is the most common malignancy of the female reproductive system. Patients with metastatic endometrial cancer have the overall 5-year survival rate of less than 20 %. The efficacy of treatment of advanced endometrial cancer remains low; therefore, the search for novel approaches for treating endometrial cancer is of great importance.Case description. We report a case of a 68-year-old female who presented with advanced endometrial cancer with metastatic lesions found in the axillary and lumbar lymph nodes, liver and lungs. The disease progressed after third-line chemotherapy, with no deficiency in the DNA repair system. The patient was successfully treated with lenvatinib and pembrolisumab. The treatment was characterized by controlled minimal toxicity and a satisfactory quality of life. At 5 months, the patient is alive with stable disease.Conclusion. Despite the progress in treating endometrial cancer including chemotherapy and hormone therapy, the prognosis of patients with metastatic endometrial cancer is poor. The discovery of new molecular markers (MSI , PD -L1) made it possible to develop a clinical approach using a combination of pembrolizumab and lenvatinib for patients with no deficiency in the repair system, for whom, the standard chemotherapy is ineffective. The presented case gives hope for the treatment of this category of patients.

Abstract PO022: Multidimensional longitudinal assessment of patients under treatment for advanced endometrial cancer: a new tool to advance research on human disease

Abstract Evolutionary biology-based methods to characterize human cancer increasingly inform screening, surveillance, and early stage disease treatment strategies. Advanced metastatic disease presents distinct challenges in research and effective treatment. We have established the Advanced Solid Tumor Registry at the Inova Schar Cancer Institute to systematically track quantitative behavior of advanced solid tumors in a “real world” treatment setting. The study supports collection of serial: plasma samples for ctDNA analysis, computed tomography digital images and semi-automated segmentation of lesions for tumor burden volume measurement, and collection of tumor marker measures among patients receiving routine, longitudinal treatment in a community oncology practice. At submission, the study has enrolled 53 patients, 6 with recurrent metastatic endometrial cancer. Study operations have been enhanced by development of R code and workflow to enable graphical display for individual patients in clinically relevant time. In addition to enhancing clinical decision-making for the individual patients, the collective endometrial cancer patient data currently cover 207 patient-months of observation, 119 circulating marker time-points, 73 CT scans, 27 individual lesions, and 20 different courses of treatment. Treatments included palliative radiation, and: cytotoxic, hormonal, immune-, and targeted therapeutics. We propose this registry represents a new tool to support application of evolutionary science-based methods to clinical care and reciprocally to collect “real world” data with sufficient detail to inform computational science assumptions and inferences in multi-scale modeling projects. In this pilot study, individual cases effectively display multiple observations relevant to understanding treatment response in advanced metastatic disease in the clinical care environment.
