Hepatotoxicity and metabolism of trabectedin: a literature review.

Trabectedin is a promising anticancer drug currently undergoing phase II evaluation. In preclinical studies, trabectedin was found to cause hepatotoxicity and in patients it reversibly increases plasma levels of liver enzymes. On the basis of preclinical work, it was suggested that metabolism of trabectedin contributed to the pharmacological effects of trabectedin, including hepatotoxicity in rats and increases in liver enzymes in humans. Our aim was to review the current literature on the metabolism of trabectedin and its role in the increases in liver enzymes and hepatotoxicity. We conclude that the trabectedin metabolic profile appears to predict the reversible nature of hepatotoxicity. The rat may not be the best species to investigate trabectedin hepatotoxicity because both trabectedin metabolic profile and reversibility of hepatotoxicity differs from humans. Humans and monkeys display a similar metabolic profile of trabectedin and in both species hepatotoxicity is reversible. Trabectedin is a drug with predictable hepatotoxic effects. Monitoring of plasma levels of liver enzymes ensures safe use of trabectedin in the clinic. Future investigations must be aimed at elucidating the mechanism of trabectedin hepatotoxicity.

In vitro toxicity of three new antitumoral drugs (trabectedin, aplidin, and kahalalide F) on hematopoietic progenitors and stem cells.

OBJECTIVE: In addition to neutropenias and/or thrombocytopenias as a short-term effect, antineoplastics also can produce long-term effects as a consequence of damage to the hematopoietic stem cells. The aim of the present study was to evaluate the toxicity of three marine-derived antineoplastics on murine hematopoietic stem cells. These antitumoral compounds currently are being evaluated in patients in phase II (aplidin and kahalalide F) and phase II/III (trabectedin) clinical trials. MATERIALS AND METHODS: Long-term competitive repopulating assays were performed in mice to analyze toxic effects on the hematopoietic stem cells responsible for the multipotential long-term repopulation of hematopoiesis. Furthermore, granulocytic and T- and B-lymphoid lineages were studied, as well as myeloid (CFU-GM) and megakaryocytic (CFU-Meg) progenitors. RESULTS: When cells were treated in vitro for 24 hours with CFU-GM IC(50) dose of trabectedin (9.59+/-4.96 nM), no significant effects were observed in the stem cells. The dose of trabectedin that produced 90% of inhibition in CFU-GM (IC(90): 23.71+/-1.27 nM) only inhibited 45% survival of stem cells. Doses of aplidin that produced reductions of 50% (56.9+/-13.32 nM) or 90% (195.88+/-21.39 nM) in myeloid progenitors did not show any effect on hematopoietic stem cells. Kahalalide F did not show any toxic effect in either short-term or long-term repopulating cells up to 10 microM. CONCLUSIONS: Our data show that the hematopoietic stem cells effects of antitumoral drugs can be properly characterized by the murine competitive repopulating assays. Our results suggest that long-term myelosuppression as a consequence of trabectedin, aplidin, or kahalalide F treatment would not be expected.

Trabectedin for women with ovarian carcinoma after treatment with platinum and taxanes fails.

PURPOSE: To assess the efficacy and toxicity of the marine-derived alkaloid trabectedin (ET-743) in patients with advanced ovarian cancer refractory to or experiencing disease relapse after platinum- and taxane-based chemotherapy. PATIENTS AND METHODS: Fifty-nine patients from four institutions either resistant (n = 30) or sensitive (n = 29) to prior platinum and taxanes were treated with a 3-hour infusion of trabectedin every 3 weeks. Patients were monitored weekly for toxicity and restaged every two cycles for response. Response was assessed according to Response Evaluation Criteria in Solid Tumors Group. RESULTS: The peer-reviewed objective response rate in platinum-sensitive patients was 43% (95% CI, 23% to 65%) with an estimated median time to progression of 7.9 months (95% CI, 7.5 to 14.1 months); in platinum-resistant patients two partial responses were observed. Responses were durable for up to 12.9 months (median, 5 months). The predominant toxicities at the recommended dose of 1,300 microg/m(2) were neutropenia, asthenia, and self-limited increase of aminotransferases never requiring treatment interruption. CONCLUSION: Trabectedin administered as a 3-hour infusion at 1,300 microg/m(2) is a safe new drug with promising activity in relapsed ovarian cancer, showing a 43% objective response rate in patients with platinum-sensitive disease, which favorably compares with other salvage treatments and warrants additional development either alone or in combination.

Simple and sensitive liquid chromatographic quantitative analysis of the novel marine anticancer drug Yondelis (ET-743, trabectedin) in human plasma using column switching and tandem mass spectrometric detection.

The development of a simple and sensitive assay for the quantitative analysis of the marine anticancer agent Yondelis (ET-743, trabectedin) in human plasma using liquid chromatography (LC) with column switching and tandem mass spectrometric (MS/MS) detection is described. After protein precipitation with methanol, diluted extracts were injected on to a small LC column (10 x 3.0 mm i.d.) for on-line concentration and further clean-up of the sample. Next, the analyte and deuterated internal standard were back-flushed on to an analytical column for separation and subsequent detection in an API 2000 triple-quadrupole mass spectrometer. The lower limit of quantitation was 0.05 ng mL(-1) using 100 micro l of plasma with a linear dynamic range up to 2.5 ng ml(-1). Validation of the method was performed according to the most recent FDA guidelines for bioanalytical method validation. The time needed for off-line sample preparation has been reduced 10-fold compared with an existing LC/MS/MS method for ET-743 in human plasma, employing a labor-intensive solid-phase extraction procedure for sample pretreatment. The proposed column switching method was successfully applied in phase II clinical trials with Yondelis and pharmacokinetic monitoring.

Yondelis (trabectedin, ET-743): the development of an anticancer agent of marine origin.

Yondelis (trabectedin, ET-743) is a novel antitumor agent derived from a marine source, the Caribbean tunicate Ecteinascidia turbinata. Preclinical studies demonstrated activity at low concentrations against a variety of tumors. The mechanism by which ET-743 exerts its antitumor activity has not been completely elucidated yet. Binding to the minor groove of DNA which causes a bend towards the major groove has been demonstrated. Furthermore, ET-743 interferes with DNA binding proteins and transcription factors. Clinical studies have been initiated as phase I dose-finding studies at four different treatment regimens. Dose-limiting toxicities were hematological, including neutropenia and thrombocytopenia. Furthermore, significant liver toxicity was observed, especially as a rise in transaminase levels. Antitumor activity in phase I and phase II trials was studied in multiple tumor types, including soft tissue sarcomas, melanomas and breast cancer. ET-743 is currently being extensively investigated in advanced soft tissue sarcomas. The present review describes the development of ET-743, highlighting chemical properties, mode of action, metabolism and preclinical and clinical studies.

Anti-inflammatory properties of the novel antitumor agent yondelis (trabectedin): inhibition of macrophage differentiation and cytokine production.

Yondelis (Trabectedin) is a novel antitumor agent of marine origin extracted from the tunicate Ecteinascidia turbinata. This original compound is active against several human tumors including sarcoma and ovarian and breast adenocarcinoma, as evidenced in phase II clinical trials in advanced multitreated patients. Yondelis is a DNA minor groove binder that blocks cell cycle and interferes with inducible gene transcription in a selective manner. In this study, we investigated the immunomodulatory properties of Yondelis on leukocytes. Human blood monocytes were highly susceptible in vitro to its cytotoxic effect and underwent apoptosis at pharmacologically relevant concentrations (5 nmol/L), whereas lymphocytes were up to 5-fold less sensitive. Macrophages differentiated in vitro with macrophage colony-stimulating factor and tumor-associated macrophages (TAM), isolated from patients with ovarian cancer, were also susceptible. At subcytotoxic concentrations, Yondelis inhibited the in vitro differentiation of monocytes to macrophages. In tumor-treated patients, drug infusion caused a selective decrease of monocyte counts and of ex vivo macrophage differentiation. The in vitro production of two proinflammatory mediators, CCL2 and IL-6, was markedly reduced by Yondelis in monocytes, macrophages, TAM, and freshly isolated ovarian tumor cells. The chemokine CCL2 is the major determinant of monocyte recruitment at tumor sites, whereas IL-6 is a growth factor for ovarian tumors. In view of the protumor activity of TAM and of the strong association between chronic inflammation and cancer progression, the inhibitory effect of Yondelis on macrophage viability, differentiation, and cytokine production is likely to contribute to the antitumor activity of this agent in inflammation-associated human tumors.

The unique biological features of the marine product Yondelis (ET-743, trabectedin) are shared by its analog ET-637, which lacks the C ring.

It was previously suggested that the peculiar mechanism of action of the novel anticancer drug Yondelis (ET-743, trabectedin) was due to part of the molecule, units A and B, binding to DNA in the minor groove, causing an alkylation at the N2 of guanine, while unit C protrudes out of DNA, possibly interacting with transcription factors or other DNA binding proteins. To test this hypothesis, we have compared the biological activity and the mode of action of Yondelis with its analogue ET-637, which has the same chemical structure except for the lack of the C ring. Yondelis and ET-637 showed similar cytotoxic potency and cell cycle perturbations. As already reported for Yondelis, the UV-96 cell line, deficient in ERCC-1, was less sensitive to ET-637 than the parental cell line. The binding of Yondelis or ET-637 to DNA-oligonucleotides was demonstrated by gel shift assay and SDS did not reverse the binding. Both compounds blocked the temperature-induced activation of the HSP40 promoter in the range of 1-10 nM. This study indicates that ET-637 acts similarly to Yondelis and demonstrates that the C ring of Yondelis may not be required for its biological activity.

The cGAS-STING pathway is a master regulator of OCT4 expression in persistent sarcoma cells and enhances cellular immunotherapy with NK and CIK lymphocytes.

Advanced sarcomas have a poor prognosis and limited therapeutic options. Disease recurrence is caused by persistent cells that survive drug treatments. The alkylating agent trabectedin, when combined with the poly (ADP-ribose) polymerase 1 (PARP1) inhibitor olaparib, exhibits variable antitumor effects in advanced sarcomas. In this study, we demonstrate that the expression of the transcription factor OCT4 is upregulated in persistent cells that survive treatment with trabectedin and olaparib, through the cGAS-STING-IRF3-IFNβ pathway. This route also leads to the upregulation of natural killer (NK) and cytokine-induced killer (CIK) lymphocyte activating ligands. These molecular events enhance the antitumor efficacy of immunotherapy with NK and CIK cells, targeting both the bulk population and residual drug-tolerant cells. In conclusion, the activation of the cGAS-STING pathway has a double-edged effect, enriching the OCT4+ persistent cell population while increasing the expression of NK/CIK ligands. The addition of olaparib to trabectedin potentiates the cGAS-STING pathway activation and the upregulation of NKG2DLs, while simultaneously counteracting the OCT4 overexpression. Therefore, sequential treatment with trabectedin and olaparib followed by NK/CIK immunotherapy represents a promising strategy against advanced sarcomas and warrants further investigation.

New drugs from the sea.

This paper illustrates some biochemical and pharmacological properties of two natural marine products such as trabectedin (ET-743, Yondelis) and aplidine. Trabectedin has shown clinical antitumor activity in refractory soft tissue sarcoma and ovarian cancer. The lack of cross resistance of trabectedin with other chemotherapeutic drugs is presumably related to its peculiar mode of action, that seems to be related to a promoter-dependent transcription modulation. Aplidine is a potent pro-apoptotic inducer in human leukemia and has antiangiogenic properties. These examples support the view that more research should be carried out to investigate new natural marine products since there are compounds among them with antitumor properties. Some of them appear to act by mechanisms different from those of conventional chemotherapeutic drugs and thus may be effective against tumors for which no active drugs are available.

Molecular characterisation of two human cancer cell lines selected in vitro for their chemotherapeutic drug resistance to ET-743.

ET-743 (Yondelis(TM), Trabectedin) isolated from the tunicate Ecteinascidia turbinata, is being tested in phase II clinical trials in Europe and the United States of America (USA). Studies with different solid tumours have shown antitumour activity in advanced, pre-treated sarcomas as well as in drug-resistant breast and ovarian cancer. The primary mechanism of action for ET-743 has not been fully elucidated and different models have been suggested to explain its molecular mechanism of action. ET-743 binds tightly to the minor groove of DNA and previous data have suggested that ET-743 acts by interfering with RNA transcription. To further investigate the mechanism of in vitro drug resistance, we evaluated the gene expression profile in ovarian and chondrosarcoma cell lines selected for resistance to ET-743. We found 70 genes whose expression was modulated in both drug-resistant cell lines when compared with their respective parental drug-sensitive cell lines. This pattern of gene expression seems to be selective for ET-743-resistant cells, since ovarian cancer cells resistant to paclitaxel did not share the same gene expression changes. Data presented in this study reveal different molecular pathways that could be involved in the cellular mechanism of ET-743 resistance.

Preclinical and clinical results with the natural marine product ET-743.

ET-743 (Yondelis, trabectedin) is a natural marine product with antitumour properties derived from the tunicate Ecteinascidia turbinata. ET-743 binds to the N2 position of guanine in the minor groove of DNA with some degree of sequence specificity, altering the transcription regulation of induced genes. Cells that are deficient in nucleotide excision repair, hypersensitive to UV rays, cisplatin and conventional alkylating agents, are resistant to ET-743. This is a unique property of ET-743 and is of potential importance for the drug activity when administered alone or in combination with other drugs. ET-743 showed striking antitumour activity against sensitive and resistant human xenografts. The dose-limiting toxicities in animal models, hepatobiliary events, were of concern, but the pattern of the reversibility noted in monkeys and the evidence of a positive therapeutic index in tumour-bearing nude mice prompted its clinical development. The Phase I programme investigated different schedules of administration, with the dose-limiting toxicities being neutropenia and fatigue. As anticipated in the preclinical models, reversible non-cumulative transaminitis was a prevalent finding from one-third of the maximum tolerated dose level; long-lasting objective responses in pretreated resistant patients were noted, including consistent efficacy data in mesenchymal tumours. The Phase II data for ET-743 administered as a single agent has established a clinical role for the compound in advanced pretreated soft tissue sarcoma and a promising potential in pretreated ovarian and breast cancer. ET-743 combined with other drugs (i.e., cisplatin, paclitaxel or doxorubicin) showed more than additive effects in several preclinical systems and initial clinical results (e.g., a combination of ET-743 with cisplatin) appear to confirm the preclinical findings. In summary, ET-743 is a new drug with a novel mode of action, which has demonstrated activity in human tumours resistant to the available anticancer drugs. Further comparative studies are needed to define the role of ET-743 alone or in combination in cancer chemotherapy.

Management of Soft Tissue and Visceral Leiomyosarcomas.

IMPORTANCE: Leiomyosarcoma is a rare and heterogeneous malignant mesenchymal neoplasm associated with substantial morbidity and mortality. Given recent advances in biologic understanding and the complexity of leiomyosarcoma, a consensus-driven approach is needed to harmonize management and address remaining clinical and research gaps. OBJECTIVE: To provide an evidence-based synthesis of current diagnostic and therapeutic approaches for leiomyosarcoma by an international panel of physicians, researchers, and patient advocates, focusing on site-specific management, systemic therapy strategies, and key areas of clinical uncertainty, while identifying unmet needs and research priorities. EVIDENCE REVIEW: This review is based on a comprehensive evaluation of the literature, including clinical trials, observational studies, and international consensus guidelines. Sources were identified through MEDLINE (via PubMed) and Embase database searches and reference screening, then supplemented by multidisciplinary expert consensus. Emphasis was placed on studies informing diagnosis, surgical management, radiotherapy, and systemic therapy in leiomyosarcoma. FINDINGS: The rarity and heterogeneity of leiomyosarcoma poses substantial challenges in its management. In localized disease, complete surgical resection remains the cornerstone of treatment, with evidence supporting the use of site-specific perioperative treatment strategies. Prospective data supporting neoadjuvant or adjuvant chemotherapy are lacking, and the role of radiotherapy differs across anatomic disease sites and institutions. In advanced disease, multiple systemic therapies demonstrate activity, including anthracycline-based and gemcitabine-based combinations, trabectedin, and tyrosine kinase inhibitors, although optimal sequencing after first-line therapy remains undefined. Emerging data suggest potential benefit from treatment continuation strategies and selected use of local therapies in oligometastatic settings. Molecular heterogeneity is increasingly recognized but has not yet translated into routine clinical implementation, and integration of molecular profiling into diagnostic pathways for predictive and therapeutic insights remains an unmet need. CONCLUSIONS AND RELEVANCE: This international consensus addresses the diagnosis and management of leiomyosarcoma. Management requires a multidisciplinary, site-specific approach informed by limited but evolving evidence. Key uncertainties persist, particularly regarding perioperative therapy, optimal sequencing and combination of systemic treatments, and integration of molecular data. Continued international collaboration and leiomyosarcoma-specific clinical trials are needed to refine treatment strategies and improve patient outcomes.

Marine-derived anticancer agents in clinical trials.

Anticancer agents may be derived either from the isolation of an active lead compound occurring spontaneously in nature or by novel chemical synthesis in the laboratory. There are examples of successful drugs being derived from both sources, which have had a profound impact on the natural history of various types of cancer. The treatment of lymphomas and acute leukaemias with the use of combination chemotherapy, including anthracyclines and vinca alkaloids, are examples of the contribution of nature. In contrast, agents such as 5-fluorouracil, methotrexate and more recently, the humanised anti-CD20 antibody rituximab and the tyrosine kinase inhibitor imatinib are examples of synthetic compounds, which were designed with a clear rationale, that are routinely used in patients with solid tumours and haematological malignancies. Until recently, the tradition in natural product-derived anticancer drug development was to rely almost exclusively on the screening of terrestrial sources (plant extracts and fermentation products) for their cytotoxic properties. Although C-nucleosides obtained from Caribbean sponge were the initial inspiration for the synthesis of antiviral substituted nucleosides and the successful anticancer agent citarabine, active against leukaemias and lymphomas, the contribution of marine compounds as a source of anticancer agents was modest. In recent years, the improvements in the technology of deep-sea collection and aquaculture added to the growing recognition of the tremendous biodiversity present in the marine world, and has contributed to the growing interest of exploring the oceans as a potential source of new anticancer candidates. This is reflected in the number of marine-derived compounds undergoing preclinical and early clinical development. In this paper, the authors discuss the available literature on anticancer agents that have reached clinical trials, such as didemnin B, aplidine, dolastatin-10, bryostatin-1 and ecteinascidin-743 (ET-743, trabectedin), as well as other promising compounds still undergoing tests in the laboratory.

Recent developments in salvage chemotherapy for patients with metastatic soft tissue sarcoma.

The number of effective cytotoxic agents for the treatment of patients with metastatic adult soft tissue sarcoma is limited, especially when patients have failed anthracycline- and ifosfamide-based chemotherapy. For the subgroup of patients with inoperable gastrointestinal stromal tumour (GIST), progress has been made via the rapid development and approval of the targeted therapy imatinib. Small round cell tumours (SRCTs), such as Ewing's sarcoma/primitive neuroectodermal tumour, desmoplastic SRCT and rhabdomyosarcoma, are chemotherapy-sensitive and potentially curable malignancies, which are treated with multimodality, dose-intensive, neoadjuvant protocols regardless of size or overt metastatic disease. Most other high-grade (grading >I), so-called 'adult type', soft tissue sarcomas such as fibrosarcoma, liposarcoma, pleomorphic and synovial sarcomas are treated with an anthracycline-based regimen with or without ifosfamide as front-line therapy. In relapsed 'adult type' soft tissue sarcomas, trofosfamide, gemcitabine and trabectedin (ecteinascidin 743) appear to be drugs associated with some activity and an acceptable toxicity profile. A high activity has been reported for the taxanes, in particular for paclitaxel, in vascular sarcomas located in the scalp or face and in Kaposi's sarcoma. It is interesting to note that the different drugs have particular effects in distinct subtypes of soft tissue sarcoma; however, it should be taken into account that the number of patients included in the phase II trials is limited. The role of the newer agents (e.g. epothilones, brostallicin) is currently undefinable. Targeted therapy inhibiting vascular endothelial growth factor receptor, epidermal growth factor receptor, RAF kinase, c-KIT or platelet-derived growth factor receptors will continue to be tested in GIST patients refractory to imatinib and in other sarcoma histologies.
