The Company has presented various studies in different types of tumors, amongst which can be highlighted the results of the study of lurbinectedin in advanced endometrial cancer that showed this molecule is active both as a single agent and when given in combination with doxorubicin (Link to the abstract).

According to Dr. Arturo Soto, Director of Clinical Development at the Oncology Business Unit at PharmaMar, "we are very pleased with the positive results obtained in endometrial cancer with lurbinectedin, both as a single agent as in combination with doxorubicin. This favorable data allows us to continue advancing and to set up a pivotal phase III study inagreement with the FDA".

Dr Andrés Poveda, Clinical Area of Gynecologic Oncology, Instituto Valenciano de Oncología, Spain, has presented the results of a dose-ranging phase I study that evaluates the safety, tolerability, pharmacokinetics and pharmacodynamics of the combination of lurbinectedin with olaparib in advanced solid tumors, where a synergistic activity between the two molecules has been observed.

PharmaMar also presented a comparison between two different clinical studies that suggests that Yondelis® and lurbinectedin are both more active in BRCA 2 than BRCA 1 metastatic breast cancer. (Link to the abstract)

Other studies to be highlighted at ASCO 2017      

1 . Trabectedin (T) as second line treatment option for patients with epithelioid malignant pleural mesothelioma (MPM) in progression following pemetrexed/platin-derivates chemotherapy: ATREUS trial.  
Trabectedin was demonstrated to be effective in terms of progression free survival (PFS) in patients with epithelioid malignant pleural mesothelioma. (Link to the abstract)

2. Correlation between a new growth modulation index (GMI)-based Geistra score and efficacy outcomes in patients (PTS) with advanced soft tissue sarcomas (ASTS) treated with trabectedin (T): A Spanish group for research on sarcomas (GEIS-38 study).  
This is a retrospective study carried out by the Spanish Group for Sarcoma Investigation that evaluates the relationship between the Growth Modulation Index, the efficacy results and the clinical   profiles of the 190 patients with ASTS. A scale of values called GEISTRA, that allows measurement and the association of the results from the patients has been established as a useful clinical tool for predicting the benefit of trabectedin.

3 .Trabectedin and radiotherapy in soft-tissue sarcoma (TRASTS) study: An international, prospective, phase I/II trial-A collaborative Spanish (GEIS), Italian (ISG), and French (FSG) groups study.
This is a European, multicenter, phase I/II prospective study in which the Spanish, Italian and French Sarcoma Groups have collaborated to analyze the combination of trabectedin and radiotherapy during the preoperative setting. The Phase I results have been presented for patients with centralized and locally advanced myeloid liposarcoma, confirming the combination is feasible and well tolerated, has good pathological results in a high percentage of patients, with a complete pathological response observed in 25% of patients.

4 .Trabectedin for advanced soft tissue sarcoma: Ten-year real-life perspective.  
This is a retrospective study about real-life experience with trabectedin. The data concludes that this molecule is a safe and effective drug in advanced high grade STS. (Link to the abstract)

5. Phase I study of lurbinectedin (PM11083) in patients with Advanced Myeloid Leukemia (AML) andMyelodysplastic Syndrome (MDS).
In this study, 42 patients with acute myeloid leukemia (AML) and relapsed/refractory myelodysplastic syndrome (MDS) were treated with lurbinectedin with the objective of determining the recommended dose. The results confirm the safety profile and tolerability of lurbinectedin. As a single agent this compound produces a transitory suppressive effect in some patients with leukemia, including some patients with an alteration in the chr11q chromosome or a mutation in the TP53 gene.
