Real-World First-Line Maintenance Niraparib Monotherapy Use Following Chemotherapy Plus Bevacizumab: The SW1TCH Study. Oncol Ther 2024; 12:465-475. [PMID: 38965204 PMCID: PMC11333408 DOI: 10.1007/s40487-024-00281-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 05/09/2024] [Indexed: 07/06/2024] Open
Abstract
INTRODUCTION Clinical trials have demonstrated prolonged survival associated with niraparib first-line maintenance (1LM) therapy, compared with placebo, for patients with ovarian cancer (OC). However, data are limited on real-world 1LM niraparib monotherapy use, particularly as switch 1LM, following first-line (1L) combination chemotherapy plus bevacizumab. This real-world study aimed to describe patient demographics, clinical characteristics, and clinical outcomes of patients with OC receiving 1LM niraparib monotherapy following 1L combination chemotherapy plus bevacizumab. METHODS This retrospective observational study used data from a US-based nationwide database of deidentified, electronic health record-derived data. Patients diagnosed with OC during the study period (1 January 2011-30 November 2022, inclusive) were eligible if they received 1L chemotherapy plus bevacizumab treatment followed by 1LM niraparib monotherapy, initiated between 1 January 2017 (inclusive) and 2 September 2022. Patients were followed from index date (initiation of niraparib 1LM) until the first occurrence of death, end of follow-up, or end of study. Clinical outcomes were time to treatment discontinuation (TTD) and time to next treatment (TTNT). Kaplan-Meier curves were used to estimate TTD, TTNT, and 95% confidence intervals (CIs). RESULTS Among 93 patients selected, median age at index was 67 years (interquartile range [IQR] 60-72 years). Most patients had BRCA wild-type/homologous recombination (HR)-proficient or BRCA wild-type/HR unknown disease (75.3%). In all, 18 (19.4%) patients had HR-deficient disease. Five (5.4%) patients had unknown test results for both BRCA and HR deficiency status. Median follow-up time was 16.3 months (IQR 8.7-25.4 months), and median time from end of 1L therapy to 1LM initiation was 35.0 days (IQR 25.0-53.9 days). Median TTD was 9.3 months (95% CI 6.1-11.3 months). Median TTNT was 12.9 months (95% CI 11.5-19.0 months). CONCLUSIONS This real-world study provided insights into switch maintenance with 1LM niraparib monotherapy, which may be a viable treatment option for patients with advanced OC.

Abstract
Ovarian cancer is the most lethal gynaecological cancer and the eighth most common female cancer. The early diagnosis of ovarian cancer remains a clinical problem despite the significant development of technology. Nearly 70% of patients with ovarian cancer are diagnosed with stages III-IV metastatic disease. Reliable diagnostic and prognostic biomarkers are currently lacking. Ovarian cancer recurrence and resistance to chemotherapy pose vital problems and translate into poor outcomes. Cancer stem cells appear to be responsible for tumour recurrence resulting from chemotherapeutic resistance. These cells are also crucial for tumour initiation due to the ability to self-renew, differentiate, avoid immune destruction, and promote inflammation and angiogenesis. Studies have confirmed an association between CSC occurrence and resistance to chemotherapy, subsequent metastases, and cancer relapses. Therefore, the elimination of CSCs appears important for overcoming drug resistance and improving prognoses. This review focuses on the expression of selected ovarian CSC markers, including CD133, CD44, CD24, CD117, and aldehyde dehydrogenase 1, which show potential prognostic significance. Some markers expressed on the surface of CSCs correlate with clinical features and can be used for the diagnosis and prognosis of ovarian cancer. However, due to the heterogeneity and plasticity of CSCs, the determination of specific CSC phenotypes is difficult.

Abstract
The mortality rate of ovarian cancer (OC) is high, posing a serious threat to women's lives. Zinc oxide nanoparticles (ZnO-NPs) show great potential in the treatment of cancer. However, the mechanism of ZnO-NPs in inhibiting the malignant proliferation and chemotherapy resistance of OC has remained elusive. In the present study, ZnO-NPs at different concentrations were used to treat SKOV3 cells, and subsequently, analyses including the Cell Counting Kit-8 assay, EDU staining, colony-formation assay, flow cytometry, wound-healing assay, Transwell assay and western blot were used to detect cell proliferation, invasion, migration, epithelial-mesenchymal transition (EMT) and chemotherapy resistance, as well as endoplasmic reticulum stress (ERS)- and autophagy-related indicators. Finally, the mechanisms of action of ZnO-NPs on OC were examined by adding ERS inhibitor 4-phenylbutyric acid (4-PBA) and autophagy inhibitor 3-methyladenine (3-MA). It was found that ZnO-NPs inhibited SKOV3 cell proliferation, facilitated apoptosis and induced cell cycle arrest. Furthermore, ZnO-NPs inhibited the invasion, migration and EMT of SKOV3 cells. ZnO-NPs also inhibited chemotherapy resistance of SKOV3 cells. ZnO-NPs activated ERS and promoted autophagy. The addition of 4-PBA or 3-MA significantly reversed the effects of ZnO-NPs on SKOV3 cells. Overall, ZnO-NPs inhibit the malignant progression and the chemotherapy resistance of SKOV3 cells by activating ERS and promoting autophagy.

Synthetic lethal interaction between WEE1 and PKMYT1 is a target for multiple low-dose treatment of high-grade serous ovarian carcinoma. NAR Cancer 2023; 5:zcad029. [PMID: 37325550 PMCID: PMC10262308 DOI: 10.1093/narcan/zcad029] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 05/24/2023] [Accepted: 05/31/2023] [Indexed: 06/17/2023] Open
Abstract
Ovarian cancer is driven by genetic alterations that necessitate protective DNA damage and replication stress responses through cell cycle control and genome maintenance. This creates specific vulnerabilities that may be exploited therapeutically. WEE1 kinase is a key cell cycle control kinase, and it has emerged as a promising cancer therapy target. However, adverse effects have limited its clinical progress, especially when tested in combination with chemotherapies. A strong genetic interaction between WEE1 and PKMYT1 led us to hypothesize that a multiple low-dose approach utilizing joint WEE1 and PKMYT1 inhibition would allow exploitation of the synthetic lethality. We found that the combination of WEE1 and PKMYT1 inhibition exhibited synergistic effects in eradicating ovarian cancer cells and organoid models at a low dose. The WEE1 and PKMYT1 inhibition synergistically promoted CDK activation. Furthermore, the combined treatment exacerbated DNA replication stress and replication catastrophe, leading to increase of the genomic instability and inflammatory STAT1 signalling activation. These findings suggest a new multiple low-dose approach to harness the potency of WEE1 inhibition through the synthetic lethal interaction with PKMYT1 that may contribute to the development of new treatments for ovarian cancer.

A Retrospective Study Comparing Olaparib and Bevacizumab as a Maintenance Therapy for Platinum-Sensitive Recurrent Ovarian Cancer: Impact on Recurrence-Free Survival in Japanese and Asian Populations. Cancers (Basel) 2023; 15:2869. [PMID: 37345206 DOI: 10.3390/cancers15102869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 05/16/2023] [Accepted: 05/19/2023] [Indexed: 06/23/2023] Open
Abstract
The use of angiogenesis inhibitors and poly ADP-ribose polymerase inhibitors following multi-agent chemotherapy, including platinum-based agents, has become the standard treatment for platinum-sensitive recurrent ovarian cancer (PSROC). However, the optimal maintenance therapy and selection criteria for these patients remain unclear. Thus, this study aimed to optimize the treatment options and selection criteria for patients with PSROC. The clinical data of 51 patients with PSROC admitted to Nippon Medical School Chiba Hokusoh Hospital and Nippon Medical School Hospital were retrospectively collected. The log-rank test was used for the survival analysis, and Cox proportional hazard regression analysis was used for the multivariate survival analysis. Of the 51 patients, 17 received maintenance therapy with bevacizumab (Bev), and 34 received olaparib (Ola). Recurrence-free survival (RFS) was significantly prolonged in the Ola group (27 months; 95% confidence interval (CI), 19-NA months) compared with that in the Bev group (9 months; 95% CI, 5-22 months; p = 0.000103). The efficacy of Ola was independent of background factors, including response to previous chemotherapy, homologous recombination status, histological type, or laboratory data. Ola is superior to Bev as PSROC maintenance therapy, especially in Japanese and Asian populations.

Abstract
The introduction of inhibitors of poly-(ADP-ribose) polymerase (PARP) for the treatment of women with epithelial ovarian cancers (EOC) has radically changed the treatment in maintenance setting after responding to first- and second-line chemotherapy. The aim of this paper was to assess the pharmacological costs of PARP inhibitors (olaparib, niraparib, rucaparib and veliparib) in maintenance treatment after responding to first-line chemotherapy in EOC. Incremental cost-effectiveness ratio (ICER) was calculated as the ratio between the difference of the costs in the intervention and in the control groups (pharmacy costs) and the difference between the effect in the intervention and in the control groups (progression-free survival (PFS)). We have considered the pivotal phase III randomized controlled trials (RCTs). Three different populations were considered: the overall population, patients with germline BRCA mutation (gBRCA) and homologous recombination deficiency (HRD) patients non-gBRCA mutation. Three thousand four hundred and twenty patients and 1209 patients were considered in maintenance treatment after responding to first- and second-line chemotherapy in EOC, respectively. At the actual price, the treatment with PARP inhibitors is not cost-effective in maintenance treatment after responding to first-line and second-line chemotherapy in EOC. A reduction in pharmacological costs is mandatory.

Abstract
OBJECTIVE This study aimed to assess the role of leukocyte immunoglobulin-like receptor A2 (LILRA2) in ovarian carcinoma (OC) oncogenesis and prognosis. MATERIALS AND METHODS Using the Cancer Genome Atlas, Genotype-Tissue Expression, and Gene Expression Omnibus databases, the association between clinicopathological profiles and LILRA2 expression was investigated using logistic regression analysis. Kaplan-Meier analysis, Cox regression analysis, and column plots predicted the clinical outcomes of patients with OC and determine the predictive value of LILRA2. The biological functions of LILRA2 were assessed using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. We used single-sample Gene Set Enrichment Analysis to investigate the relationship between immune cell infiltration and LILRA2 expression. RESULTS LILRA2 expression in OC tumors was significantly higher than in normal tissue (P < 0.05). The high LILRA2 expression in OC was correlated with lymphatic invasion (P = 0.014). The results showed consistency indices of 0.611 [95% confidence interval (CI), 0.572-0.649] and 0.623 (95% CI, 0.584-0.663) for the overall and disease-specific survival nomograms, respectively. Cox regression analysis showed that LILRA2 was an independent risk factor for overall survival (hazard ratio [HR], 1.511; P = 0.002) and disease-specific survival (HR, 1.537; P = 0.003). Functional annotation revealed enrichment with immunoglobulin-corresponding pathways when LILRA2 expression was high. CONCLUSION By evaluating gene expression profiles, we demonstrated that LILRA2 has considerable potential to act as a therapeutic target and prognostic biomarker in OC.

Abstract
AbstractOvarian malignancy is the seventh most frequently diagnosed cancer among women. The most common type is epithelial ovarian cancer. Several subtypes with distinct biological and molecular properties exist, and there is inconsistency in availability of and access to different modalities of treatment. The standard first-line management is combining surgery and platinum-based chemotherapy. Most of them are diagnosed at an advanced stage due to which they have poor outcomes. The existing screening tests have a low predictive value. Even with the best available upfront treatment, high rates of recurrences are observed. As a result, there have been major advances in the treatment of recurrences with the development of anti-angiogenic agents and PARP inhibitors. It has led to the improvement in survival and quality of life among the relapsed epithelial ovarian cancers. This review is focused on the management of recurrent epithelial ovarian cancers and future directions based on current evidence. The application of a personalized and structured approach will meaningfully bring changes in the paradigm of care in these groups of patients.

Abstract
The advent of molecular targeted therapies has made a significant impact on survival of women with ovarian cancer who have defects in homologous recombination repair (HRR). High-grade serous ovarian cancer (HGSOC) is the most common histological subtype of ovarian cancer, with over 50% displaying defective HRR. Poly ADP ribose polymerases (PARPs) are a family of enzymes that catalyse the transfer of ADP-ribose to target proteins, functioning in fundamental cellular processes including transcription, chromatin remodelling and DNA repair. In cells with deficient HRR, PARP inhibitors (PARPis) cause synthetic lethality leading to cell death. Despite the major advances that PARPis have heralded for women with ovarian cancer, questions and challenges remain, including: can the benefits of PARPis be brought to a wider range of women with ovarian cancer; can other drugs in clinical use function in a similar way or with greater efficacy than currently clinically approved PARPis; what can we learn from long-term responders to PARPis; can PARPis sensitise ovarian cancer cells to immunotherapy; and can synthetic lethal strategies be employed more broadly to develop new therapies for women with ovarian cancer. We examine these, and other, questions with focus on improving outcomes for women with ovarian cancer.

Abstract
Ovarian cancer is the eminent gynecological malignancy and chemoresistance remains a major reason for poor in ovarian cancer patients. Taxol has been proved as the most effective chemotherapeutic agent against ovarian cancer. However development of Taxol resistance remains a major problem. Here, we report that STAT3, directly activates pentose-phosphate pathway to exert pro-oncogenic effects on Taxol resistance of ovarian cancer. In addition, we found that STAT3, p-STAT3 and glucose-6-phosphate dehydrogenase (G6PD) protein levels are upregulated in Taxol resistant cell lines compared with Taxol sensitive cell lines. Furthermore, inhibition of STAT3 decreased G6PD mRNA expression level and enhanced the sensitivity of Taxol resistant cell to Taxol. Finally, we found that STAT3 directly binds to the G6PD promoter region and promotes the expression of G6PD at transcriptional level. Taken together, our data indicate that activation of STAT3 promotes ovarian cancer cell proliferation, colony formation, and Taxol resistance via augmenting G6PD expression and pentose-phosphate metabolism flux, which provides a potential therapeutic target that may improve prognosis by decreasing G6PD expression and enhancing Taxol-sensitivity.

Abstract
Background: The different pharmacological effects of drugs in different people can be explained by the polymorphisms of drug metabolism-related genes. Emerging studies have realized the importance of drug metabolism-related genes in the treatment and prognosis of cancers, including ovarian cancer (OV). In this study, using comprehensive bioinformatics and western blot, we identified that the drug metabolism-related gene, ADH1B, was significantly down-regulated in OV cells and tissues. The patients with a high level of ADH1B presented a good prognosis. We also found a negative correlation between ADH1B expression and the activity of chemotherapeutic agents, such as cyclophosphamide. In addition, positive correlations were observed between ADH1B expression and multiple immune checkpoints, including LAG3 and HAVCR2. The immune infiltration analysis further indicated that aberrantly expressed ADH1B might have important roles in regulating the infiltration of macrophages and neutrophils in OV tissues. Then, the co-expression analysis was conducted and the top three enriched KEGG pathways were spliceosome, RNA transport, and DNA replication. In conclusion, the drug metabolism-related gene ADH1B and its interactive network play an essential role in the immune regulation and therapeutic response and maybe identified as promising therapeutic targets for OV patients.

Lorusso D, Guy H, Samyshkin Y, Hawkes C, Estenson K, Coleman RL. Feasibility Study of a Network Meta-Analysis and Unanchored Population-Adjusted Indirect Treatment Comparison of Niraparib, Olaparib, and Bevacizumab as Maintenance Therapies in Patients with Newly Diagnosed Advanced Ovarian Cancer. Cancers (Basel) 2022; 14:1285. [PMID: 35267593 PMCID: PMC8909094 DOI: 10.3390/cancers14051285] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 02/22/2022] [Accepted: 02/23/2022] [Indexed: 01/27/2023] Open
Abstract
Selecting a first-line (1L) maintenance option for ovarian cancer is challenging given the variety of therapies, differing trials, and the lack of head-to-head data for angiogenesis and poly(ADP-ribose) polymerase (PARP) inhibitors. Thus, indirect treatment comparisons (ITCs) can aid treatment decision making. This study assessed the feasibility of two ITCs, a network meta-analysis (NMA) and a population-adjusted ITC (PAIC), comparing the efficacy of the PARP inhibitor niraparib in the PRIMA trial (NCT02655016) with other 1L maintenance treatments. A systematic literature review was conducted to identify trials using the Cochrane Handbook for Systematic Reviews of Interventions to assess differences in trial design, population characteristics, treatment arms, and outcome measures. All 12 trials identified were excluded from the NMA due to the absence of a common comparator and differences in survival measures and/or inclusion criteria. The PAIC comparing PRIMA and PAOLA-1 trials was also not feasible due to differences in inclusion criteria, survival measures, and the previous receipt of chemotherapy/bevacizumab. Neither ITC met recommended guidelines for analysis; the results of such comparisons would not be considered appropriate evidence when selecting 1L maintenance options in ovarian cancer. ITCs in this setting should be performed cautiously, as many factors can preclude objective trial comparisons.

Cancer Angiogenesis and Opportunity of Influence on Tumor by Changing Vascularization. J Pers Med 2022; 12:jpm12030327. [PMID: 35330327 PMCID: PMC8954734 DOI: 10.3390/jpm12030327] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 02/18/2022] [Accepted: 02/18/2022] [Indexed: 12/19/2022] Open
Abstract
Based on the study of recent scientific literature devoted to neovascularization and angiogenesis in malignant neoplasms, it was concluded that there are many publications on each of the problems of tumor angiogenesis and vascularization. The formation of blood vessels in a tumor and certain aspects of the prognostic value of the severity of vascularization in almost all forms of cancer are considered. Special attention is paid to the peculiarities of angiogenesis in tumors of the female reproductive system. A large number of vessels in the tumor often indicates a poor prognosis. The influence of various factors on the initiation of angiogenesis and the process itself, as well as the possibility of suppressing such signals to slow down the formation of blood vessels and thus the development of the tumor are widely studied. The results of pharmacological suppression of tumor vessel formation demonstrate a good clinical outcome but one accompanied by a large number of severe adverse side effects. Such a significant amount of studies on each of the problems of tumor vascularization indicates the increasing importance of this area of oncology. At the same time, only a very small number of works are devoted to the study of the differences in angiogenesis and number of vessels between different parts of the tumor, as well as between the primary tumor node and its metastases. The refinement of the results is still to be done. It was noted that the expression of proangiogenic factors in metastases is usually higher than in the source of metastasis, and the expression in lymphogenous metastases is higher than in hematogenous ones.

Treatment Experience and Predictive Factors Associated with Response in Platinum-Resistant Recurrent Ovarian Cancer: A Retrospective Single-Institution Study. J Clin Med 2021; 10:jcm10163596. [PMID: 34441892 PMCID: PMC8397105 DOI: 10.3390/jcm10163596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/13/2021] [Accepted: 08/14/2021] [Indexed: 11/17/2022] Open
Abstract
Ovarian cancer (OC) represents the most common and lethal gynecologic malignancy, due to its increased incidence and mortality rate. It is usually diagnosed in advanced stages and, even though surgery and platinum-based treatments are initially efficient, recurrences emerge in over 70% of cases. Although there are multiple options of chemotherapy drugs from which to choose, little is known regarding the best strategy for prolonged survival. Thus, this study aimed to assess the effect that most frequently used chemotherapeutic regimens have upon time-to-treatment-failure (TTF) from the first line and beyond, considering clinical and biological factors which influence the treatment outcome of platinum-resistant recurrent OC. We retrospectively analyzed data from 78 patients diagnosed with platinum-resistant OC, who underwent chemotherapy-based treatment with or without anti-angiogenic therapy at OncoHelp Oncology Center, Romania (January 2016–February 2021). Our study identified positive predictive factors for TTF related to histology (serous carcinoma subtype), anthropometry (age over 60 for patients treated with topotecan with or without bevacizumab), renal function (creatinine levels between 0.65 and 1 mg/dL for patients treated with regimens containing bevacizumab and pegylated liposomal doxorubicin) and treatment choice (bevacizumab in combination with pegylated liposomal doxorubicin or topotecan used from the first line and beyond).

Abstract
OBJECTIVES The clinical utility of maintenance therapy (MT) for patients with platinum-sensitive recurrent ovarian cancer has been validated in several clinical trials. We assessed "real-world" treatment patterns using an electronic health record (EHR) database. METHODS A retrospective study of patients diagnosed with ovarian cancer between January 1, 2011 and July 31, 2019 was conducted using the US nationwide Flatiron Health (EHR)-derived de-identified database. Patients were included if they received second- or third-line (2 L or 3 L) platinum-based chemotherapy (PBCT). Information regarding biomarker status was obtained. RESULTS 2292 patients with ovarian cancer received at least two lines of therapy. 222 patients completed PBCT on or after March 1, 2017 and had ≥2 months of active surveillance or received MT with poly(adenosine diphosphate-ribose) polymerase inhibitors (PARPi) or bevacizumab. 46 (20%) had BRCA mutations (BRCAm), 132 (59%) had a wildtype BRCA (BRCAwt) gene, and 47 (21%) were unknown. Of patients with BRCAm, 63% received a PARPi, 17% received bevacizumab, and 20% underwent active surveillance. Of patients with BRCAwt, 40% received a PARPi, 23% received bevacizumab, and 36% underwent active surveillance. MT was more common in those with younger age and a BRCA mutation. PARPi use increased on average by 1.3% every 3 months (p = .02) with no statistically significant change in use of bevacizumab. CONCLUSIONS In this real-world population, MT is becoming progressively more common following 2 L or 3 L PBCT regardless of biomarker status. The results provide insight into the shifting treatment patterns for patients with recurrent ovarian cancer.

Abstract
Ovarian cancer is one of the leading causes of female cancer death. Emerging evidence suggests that many dietary natural products have anti-tumorigenic activity, including that of asparagus officinalis. The current study aimed to assess the anti-tumorigenic and anti-metastatic effects of asparagus officinalis on serous ovarian cancer cell lines and a transgenic mouse model of high grade serous ovarian cancer. Asparagus officinalis decreased cellular viability, caused cell cycle G1 phase arrest and induced apoptosis in the OVCAR5 and SKOV3 cells. Induction of apoptosis and inhibition of cell proliferation was rescued by the pan-caspase inhibitor, Z-VAD-FMK, implying that its cytotoxic effects were mainly dependent on caspase pathways. Asparagus officinalis increased levels of ROS and decreased mitochondrial membrane potential with corresponding increases in PERK, Bip, Calnexin PDI and ATF4 in both cell lines. Treatment with asparagus officinalis also reduced ability of adhesion and invasion through epithelial-mesenchymal transition and reduction of VEGF expression. The combination of Asparagus officinalis with paclitaxel had synergistic anti-proliferative activity. Furthermore, Asparagus officinalis significantly inhibited tumor growth and reduced serum VEGF in a genetically engineered mouse model of ovarian cancer under obese and lean conditions, accompanied with a decrease in the expression of Ki67, VEGF and phosphorylated S6, and in an increase in phosphorylation of AMPK in the ovarian tumor tissues. Overall, our data provide a pre-clinical rationale for asparagus officinalis in the prevention and treatment of ovarian cancer as a novel natural product.

Abstract
Introduction: The efficacy and safety of trabectedin/pegylated liposomal doxorubicin (trabectedin/PLD) in patients with recurrent ovarian cancer have been demonstrated in randomized clinical studies. Real-world evidence is a subsequent necessary step for completing information from clinical practice. In the case of trabectedin/PLD, this evidence derives from prospective studies, retrospective analyses, and case series.Areas covered: The present narrative review provides the most relevant data about efficacy and safety of trabectedin/PLD in real-world studies, and the interpretation of the experience with trabectedin/PLD in clinical practice for patients with recurrent ovarian cancer.Expert opinion: Trabectedin/PLD has a proven antitumor activity that is maintained when administered in advanced lines. Trabectedin/PLD in patients who have relapsed between 6 and 12 months have showed comparable survival outcomes than platinum-based regimens. Moreover, the administration of trabectedin/PLD was associated with a positive survival trend after two previous platinum lines and a significantly superior PFS after subsequent platinum-based therapy. Additionally, the activity of trabectedin seems to be increased in patients with BRCA-mutated ovarian cancer. Overall, real-word evidence has confirmed that trabectedin/PLD is an effective and safe non-platinum combination for advanced lines of chemotherapy in patients with platinum-sensitive recurrent ovarian cancer.

Abstract
Drug resistance hinders effectiveness of human ovarian cancer (OC) therapies, such as cisplatin or paclitaxel therapy. Although dacomitinib, a novel anticancer agent is used against multiple types of cancers, such as non-small cell lung cancer, head and neck cancer, few studies report its effectiveness in drug-resistant human OC cells. In the present study, would healing, microplate spectrophotometer analysis, flow cytometry analysis, western blotting and Gene Expression Omnibus (GEO) analysis were used to detect the synergistic effect of dacomitinib and cisplatin in human OC SKOV-3 or OV-4 cells. Co-administration of dacomitinib and cisplatin significantly reduced viability and promoted cell apoptosis of drug resistant OC cells. In addition, dacomitinib increased Cadherin 1 (CDH1) levels and decreased P-glycoprotein (P-GP) levels in cisplatin-resistant OC cells. In addition, GEO analysis demonstrated that dacomitinib inhibited the epidermal growth factor receptor (EGFR) signaling pathway. In summary, dacomitinib improves chemosensitivity of cisplatin in human OC by regulating CDH1 and P-GP protein levels and inhibiting the EGFR signaling pathway.

Phase I Study of Rucaparib in Combination with Bevacizumab in Ovarian Cancer Patients: Maximum Tolerated Dose and Pharmacokinetic Profile. Target Oncol 2020; 16:59-68. [PMID: 33369704 PMCID: PMC7810645 DOI: 10.1007/s11523-020-00780-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/13/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Targeted agents, such as antiangiogenic drugs (e.g., bevacizumab) and poly(ADP-ribose) polymerase inhibitors (e.g., rucaparib), have been shown to improve outcomes in patients with newly diagnosed or recurrent ovarian cancer. Evidence suggests that combinations of these two classes of targeted agents may result in synergistic antitumor activity. OBJECTIVE The phase I portion of MITO 25 was designed to determine the maximum tolerated dose, pharmacokinetics, and the safety profile of rucaparib when administered in combination with bevacizumab as maintenance treatment for patients with high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer. METHODS This was a single-arm, phase I dose-escalation study. Cohorts of three patients were recruited to receive increasing rucaparib doses of 400 mg, 500 mg, or 600 mg twice daily for 28 days. Bevacizumab 15 mg/kg was administered at day 1 every 21 days. RESULTS We enrolled nine patients. Two patients in the rucaparib 600-mg group had four grade 3 treatment-emergent adverse events: increased in alanine aminotransferase and aspartate aminotransferase levels, depression, and hallucinations. These were deemed to be dose-limiting toxicities related to rucaparib. Because these dose-limiting toxicities occurred in the 600-mg group and affected more than one in three patients, the maximum tolerated dose for rucaparib was considered 500 mg twice daily when combined with bevacizumab 15 mg/kg at day 1 every 21 days. There were no new safety concerns from using the combination. No substantial difference in pharmacokinetic parameters was found between the cohorts or in the pharmacokinetic profiles of rucaparib administered alone or with bevacizumab with respect to historical controls. CONCLUSIONS The maximum tolerated dose of rucaparib is 500 mg twice daily when co-administered with bevacizumab. The plasma concentration-time profiles of rucaparib in combination with bevacizumab suggest no pharmacokinetic interactions between the drugs. The randomized phase II portion of MITO 25 will further investigate rucaparib maintenance treatment with or without bevacizumab in patients with newly diagnosed stage III-IV ovarian cancer who responded to carboplatin-paclitaxel chemotherapy with or without bevacizumab. TRIAL REGISTRATION ClinicalTrials.gov identifier NCT03462212; registered March 2018.
