Joshua K. Sabari, MD, discusses how, despite the relatively small numbers of CRs and PRs in the DeLLphi-301 trial, the DOR to tarlatamab (exceeding 6 months in 59% of patients and more than 9 months in 29%) is promising, particularly considering that more than 50% of responders maintained their response at the data cutoff, indicating potential long-term benefits in this treatment setting.

Joshua K. Sabari, MD, discusses how the ORR of 32% to 40% observed in the DeLLphi-301 clinical trial among participants receiving tarlatamab is clinically meaningful, particularly given that these responses occurred between 5 and 7 weeks after initiation and emphasize the importance of ORR as a primary end point in evaluating the efficacy of treatment in this patient population.

Joshua K. Sabari, MD, discusses how tarlatamab, a BiTE, demonstrates a unique mechanism of action by targeting DLL3, which is aberrantly expressed in 85% to 94% of SCLC cells, thereby directing T cells to these cancer cells independently of MHC class I and promoting T-cell–mediated tumor lysis and regression.

Joshua K. Sabari, MD, discusses how, despite negative results from serial brain MRIs, the consideration of PCI in patients with ES-SCLC depends on individual risk factors, including the likelihood of brain metastases and the overall treatment strategy aimed at improving outcomes.

Dr. Sabari discusses how, for extensive stage small cell lung cancer (ES-SCLC) that progresses within six months after platinum-based chemoimmunotherapy and immunotherapy maintenance, options like lurbinectedin, topotecan, and irinotecan are considered viable subsequent treatments due to their proven effectiveness in similar clinical scenarios.

Panelists discuss how managing extensive stage small cell lung cancer involves balancing the survival benefits of subsequent therapies with the risks of treatment-related adverse events, emphasizing the importance of individualized treatment strategies.
