> The Company has the agreement of the study design in accordance with the FDA

PharmaMar (MSE:PHM) will present data obtained from various clinical studies for its activated transcription inhibitors, Yondelis® and lurbinectedin, during the 53rd Congress of the American Society of Clinical Oncology (ASCO) that will be held from the 2nd to the 6th of June in Chicago (USA).

During this congress, PharmaMar will participate with various presentations for Yondelis® in malignant pleural mesothelioma, along with the data of a prospective study of the combination with radiotherapy in soft tissue sarcoma.

The Company will also present data for lurbinectedin (PM1183) for the treatment of endometrial cancer and BRCA 2-associated metastatic breast cancer. The results will also be presented on a Phase I study that evaluated the combination of lurbinectedin with olaparib in patients with advanced solid tumors.

“After the positive results obtained in endometrial cancer with lurbinectedin, as a single agent and in combination with doxorubicin (abstract 6658), we plan to initiate a pivotal Phase III study. We have reached an agreement with the US FDA on the design of the study”, explains Dr Arturo Soto, Head of Clinical Development at the Oncology Business Unit at PharmaMar. “We will continue with our commitment to finding innovative solutions for cancer patients from compounds of a marine origin that have the characteristic for combating cancer with a novel mechanism of action”, states.

The studies presented during this congress are available on http://abstracts.asco.org

About lurbinectedin

PM1183 is a compound under clinical investigation. It is an inhibitor of RNA polymerase II. This enzyme is essential for the transcription process that is over-activated in tumors with transcription addiction. The antitumor efficacy of lurbinectedin is being investigated in various types of solid tumors, including a Phase III study for platinum-resistant ovarian cancer, a Phase II study for BRCA 1 and BRCA 2-associated metastatic breast cancer and a Phase III study for small cell lung cancer.
