Phase 2 or 3 results paper on Tarlatamab in Small-cell lung cancer, in New England Journal of Medicine (2025), one of the most cited Europe PMC records with Tarlatamab in its title.
Background: Tarlatamab, a bispecific delta-like ligand 3-directed T-cell engager immunotherapy, received accelerated approval for the treatment of patients with previously treated small-cell lung cancer. Whether tarlatamab is more effective than chemotherapy in the treatment of patients whose small-cell lung cancer has progressed during or after initial platinum-based chemotherapy is not known.
Methods: We conducted a multinational, phase 3, open-label trial to compare tarlatamab with chemotherapy as second-line treatment in patients with small-cell lung cancer whose disease had progressed during or after platinum-based chemotherapy. Patients were randomly assigned to receive tarlatamab or chemotherapy (topotecan, lurbinectedin, or amrubicin). The primary end point was overall survival. Key secondary end points were investigator-assessed progression-free survival and patient-reported outcomes. Results of the prespecified interim analysis (data-cutoff date, January 29, 2025) are reported.
Results: A total of 509 patients were randomly assigned to receive tarlatamab (254 patients) or chemotherapy (255 patients). Treatment with tarlatamab resulted in significantly longer overall survival than chemotherapy (median, 13.6 months [95% confidence interval {CI}, 11.1 to not reached] vs. 8.3 months [95% CI, 7.0 to 10.2]; stratified hazard ratio for death, 0.60; 95% CI, 0.47 to 0.77; P<0.001). Tarlatamab treatment also had a significant benefit with respect to progression-free survival and cancer-related dyspnea and cough as compared with chemotherapy. The incidence of adverse events of grade 3 or higher was lower with tarlatamab than with chemotherapy (54% vs. 80%), as was the incidence of adverse events resulting in treatment discontinuation (5% vs. 12%).
Conclusions: Treatment with tarlatamab led to longer overall survival than chemotherapy among patients with small-cell lung cancer whose disease had progressed during or after platinum-based chemotherapy. (Funded by Amgen; DeLLphi-304 ClinicalTrials.gov number, NCT05740566.).
Indexed on Europe PMC as PubMed record 40454646 (DOI 10.1056/nejmoa2502099). Its title names Tarlatamab and its text names Small-cell lung cancer; PubMed types it as a clinical trial report (Clinical Trial, Phase III, Comparative Study, Multicenter Study, Randomized Controlled Trial). It was matched automatically to the idea "Subtype-directed therapy for SCLC (ASCL1 / NEUROD1 / POU2F3 / inflamed)" and no figure has been checked by an editor.
One of the most cited trial reports Europe PMC returns for Tarlatamab in Small-cell lung cancer, so it is a natural first reading for anyone weighing the idea it is linked from. The record was linked automatically by title and abstract; read the abstract above and the paper itself before relying on any figure.
