This news release is available in Spanish.

  • Compelling clinical activity of PM1183 in second line, achieving 67% response rate and a progression-free survival of 4.7 months in patients with small cell lung cancer (SCLC), a type of tumor with very limited treatment alternatives

  • Data from an interim analysis from the pivotal Phase 3 trial of YONDELIS® in soft tissue sarcoma, SAR-3007, will be presented in an oral presentation

  • Phase 2 data showcase activity of YONDELIS® in malignant pleural mesothelioma, a rare form of lung cancer that is largely related to asbestos exposure and for which effective therapies are lacking

Madrid, May 14, 2015: PharmaMar announces that it will present several clinical studies to showcase the data obtained in various tumor types, including SCLC, soft tissue sarcoma and mesothelioma during the 51st American Society of Clinical Oncology meeting in Chicago (ASCO; May 29-June 2). Abstracts have been selected for oral presentation, poster discussion session and general poster presentation. The studies presented by the Company will include the first-in-class drug YONDELIS® (trabectedin), and the second-generation of this class, PM1183 (lurbinectedin). PM1183 is an inhibitor of the transcriptional machinery and a DNA repair complex, which have proven to be crucial in different tumor types, including SCLC, soft tissue sarcoma and ovarian cancer. In addition, these drugs have been shown to have an effect on the tumor microenvironment by targeting tumor-associated macrophages, which is relevant for cancers such as mesothelioma and ovarian cancer, in which chronic inflammation seems to be a hallmark of the disease.

"PharmaMar continues to advance cancer care through the development of innovative anticancer drugs that target tumors in a way that no one is doing. We are identifying new ways to tackle the root of the disease, and our new class of drugs shows efficacy even in difficult-to-treat tumors, such as small cell lung cancer, mesothelioma and soft tissue sarcoma", says Nadia Badri, MD, VP Medical Affairs, PharmaMar. "The events that will take place this year are crucial for PharmaMar as we move forward in the oncology arena, and this forum is the perfect scenario to feature our clinical programs"

About YONDELIS® (trabectedin)

YONDELIS® (trabectedin) is a novel, multimodal, synthetically produced antitumor agent, originally derived from the sea squirt, Ecteinascidia turbinata. The drug exerts its activity by targeting the transcriptional machinery. It is approved in 80 countries in North America, Europe, South America and Asia for the treatment of advanced soft tissue sarcomas as a single-agent and for relapsed ovarian cancer in combination with DOXIL®/CAELYX® (doxorubicin HCl liposome injection). Under a licensing agreement with PharmaMar, Janssen Products, L.P. has the rights to develop and sell YONDELIS® globally except in Europe, where PharmaMar holds the rights, and in Japan, where PharmaMar has granted a license to Taiho Pharmaceuticals.

About PM1183 (lurbinectedin)

PM1183 is an investigational drug from the class of inhibitors of the enzyme RNA polymerase II, which is crucially involved in transcription. By targeting transcription, the drug inhibits the expression of factors important for tumor progression, and impairs the DNA repair system called NER, thereby enhancing tumor cell killing. PM1183 (lurbinectedin) is currently being investigated in different tumor types, including a Phase 3 study for platinum-resistant ovarian cancer, a Phase 2 study for BRCA1/2-associated metastatic breast cancer and a Phase 1b study for small cell lung cancer.
