La Biotecnológica inicia el mes de agosto en plena zona de resistencia. Tras la visita “relámpago” “al soporte de los 1.80 euros zonales protagonizada el pasado día 24 de junio, Zeltia ha logrado consolidar una tímida, pero continuada, tendencia de recuperación alcista que de momento le ha acercado al antiguo soporte estructural de los 2.40 euros zonales. Dicho movimiento le ha permitido cruzarse al alza con su media móvil de 30 sesiones, acontecimiento que prácticamente se ha producido a la par con la entrada en terreno positivo de su indicador técnico MACD, síntomas de que el actual rebote técnico podría tener continuidad durante las próximas semanas.

PharmaMar is starting a new Phase III trial, with patients suffering from small cell lung cancer (SCLC). It’ll test the efficacy of its third candidate obtained from marine organisms (PM1183) as a SCLC treatment.
Now, PM1183 is under the spotlight. This cancer drug will be used in a second Phase III trial (after ovarian cancer). It’ll enrol 600 patients with small cell lung cancer (SCLC), for whomplatinum-based treatments have failed before.
This type of lung cancer is less common than non-small cell lung cancer (which has very bad statistics) but has the worstprognosis for pulmonary cancers. Five years after diagnosis, only 5% to 10% of the patients are still alive.

The trial will evaluate the efficacy of PM1183 as a therapy, in combination withdoxorubicin (chemotherapy drug). The therapy’s effect on the progression-free-survival (PFS) of patients will be compared to those undergoing to other treatments – a chemotherapy combination (cyclophosphamide, doxorubicin and vincristine) or topotecan.
Topotecan is currently the only drug approved for this condition, both in the US and in Europe. This lack of therapyoptions also contributes to the poor outlook of small cell lung cancer. If successful, PM1183 would be able to cover a high unmet medical need.

PharmaMar’s PM1183 (also known aslurbinectedin) acts as an inhibitor of RNA polymerase II, an enzyme involved in thetranscription of DNA. In certain types of tumor, the transcription is over-activated – a process where this enzyme is essential.
As with PharmaMar’s other candidates, this drug is the result of a research program to find marine compounds with antitumor activity. The strategy already yielded Yondelis, approved to treat soft tissue sarcoma and ovarian cancer.
