Dr. Joshua Sabari from NYU Langone moderated a comprehensive discussion with Drs. Anne Chiang, Jacob Sands, Misty Shields, and Ticiana Leal on evolving maintenance strategies for extensive-stage small cell lung cancer (ES-SCLC).
The program centered on the IMforte trial, demonstrating that lurbinectedin plus atezolizumab maintenance reduced progression risk by 46% and death risk by 27% versus atezolizumab alone, with median overall survival benefit of approximately 3 months from randomization. The panel addressed practical considerations including myelosuppression management, G-CSF prophylaxis, and patient selection criteria excluding those with brain metastases or ECOG performance status above 1.
Significant attention focused on tarlatamab, a DLL3-targeted bispecific T-cell engager showing remarkable second-line efficacy (DeLLphi-304) and promising first-line maintenance data (DeLLphi-303) with 82% 1-year overall survival, with the phase 3 DeLLphi-305 trial ongoing.
The discussion emphasized individualized treatment approaches, multidisciplinary palliative care integration, brain metastasis surveillance strategies, and the evolving role of platinum rechallenge. Panelists highlighted the importance of early, aggressive treatment given high patient attrition rates and discussed emerging therapies including antibody-drug conjugates and radioligand therapies.
