Emerging drugs for small cell lung cancer--an update

Abstract

Introduction: Small cell lung cancer (SCLC) is a biologically complex tumor whose medical treatment has remained largely unchanged over the last 30 years. The frustration for the invariably negative results reported in the early 2000s in clinical studies investigating new agents for this disease have contributed to the little interest shown by pharmaceutical industries in funding SCLC research. However, recent advances in the molecular understanding of the oncogenic mechanisms underlying SCLC have renewed the attraction for the clinical development of novel active drugs for the treatment of this challenging disease.

Areas covered: The authors briefly touch on the most promising agents under clinical development for the treatment of SCLC, either chemotherapeutic or targeted drugs. Relevant and recent (2 years) studies obtained through Pubmed literature research or released at International scientific meetings are presented.

Expert opinion: The data discussed herein provide evidence in support of the fact that only rationally designed clinical trials including relevant translational research may lead to successful results. Therefore, a thoughtful change in trial construction is crucial for the approval of new active drugs for this orphan disease.
