PharmaMar (PHM:MSE) today announced that its Phase II trial of lurbinectedin as a single agent for the treatment of relapsed small cell lung cancer (SCLC) has achieved its primary endpoint, by both investigator review and IRC (Independent Review Committee).

The primary endpoint of this trial was to measure the Overall Response Rate (ORR), with other secondary endpoints such as Duration of Response (DOR), ProgressionFree Survival (PFS), Overall Survival (OS) and safety.

This multicenter, single arm, phase II clinical trial, involving 105 patients from 38 centers in nine different countries in Europe and the US, assessed the safety and efficacy of lurbinectedin in patients with relapsed SCLC.

The results will be submitted for presentation at a major medical meeting.

Around 15% to 20% of lung cancers are small cell, and it is one of the cancer types with the worst prognosis. The treatment of relapsed SCLC has not changed substantially in more than two decades. The last FDA approved new chemical entity in second line small cell lung cancer was topotecan, in 1996.

In the lurbinectedin clinical program, the SCLC indication is currently PharmaMar’s first priority. PharmaMar completed the recruitment in July 2018 of its Phase III ATLANTIS study for the treatment of relapsed SCLC. The Company is awaiting results.

Lurbinectedin was designated an Orphan Drug by the FDA in August 2018, and a positive opinion for Orphan Drug Designation by EMA was received in January 2019 for the treatment of SCLC.
