“Lurbinectedin (Zepsyre; PM1183) plus doxorubicin demonstrated significant clinical activity as a second-line therapy for patients with small cell lung cancer (SCLC), especially when excluding refractory patients.
“In particular, patients with chemotherapy-free intervals (CTFIs) of 90 days or more induced a 53% overall response rate (ORR) and PFS of 5.7 months, according to findings that were presented at the 19th World Conference on Lung Cancer (WCLC) in Toronto, Canada.”
Cancers that arise in the lung are mostly of the type known as NSCLC (non-small cell lung carcinoma). A much smaller proportion of lung tumors arise from neuroendocrine cells in the lungs. These cells (which are also found in most other organs) secrete a variety of hormones that are necessary for normal organ function, as well as for healing after injury or infection. Like other lung cells, neuroendocrine cells may transform to become cancers. Lung cancers that arise from neuroendocrine cells are called pulmonary neuroendocrine tumors (NETs), or lung NETs.

“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.”
