Joshua K. Sabari, MD, evaluates the objective clinical outcomes of emerging targeted therapies for ES-SCLC, comparing them with second-line topotecan and CAV regimens, while discussing the potential of various compounds for platinum-sensitive vs platinum-resistant subgroups. He also considers the applicability of TIGIT immunotherapy, highlighting the need for robust clinical trial data on its safety and efficacy as both monotherapy and in combination, and he reflects on whether tiragolumab is more suited for chemotherapy-naive non–small cell lung cancer than for ES-SCLC, based on the phase 2 CITYSCAPE trial results.

Joshua K. Sabari, MD, discusses the antitumor activity of second-line lurbinectedin, noting an ORR of 45%, a median DOR of 6.2 months, and a median OS of 11.2 months in patients with relapsed SCLC, and emphasizes the need for further studies to validate these findings in those with longer chemotherapy-free intervals while considering factors that may lead to lurbinectedin’s use over chemotherapy in candidates for platinum rechallenge, as well as the potential role of G-CSFs for prophylaxis.

Joshua K. Sabari, MD, describes the mechanism of action of lurbinectedin as a synthetic alkaloid that binds to guanine residues in the minor groove of DNA, forming adducts that disrupt DNA repair mechanisms and promote apoptosis in cancer cells, noting that its action contrasts with traditional alkylating agents by specifically interfering with DNA-protein interactions and transcription processes.
