Ticiana Leal, MD, discusses how tarlatamab, a bispecific T-cell engager (BiTE), leverages the aberrant expression of delta-like ligand 3 on small cell lung cancer (SCLC) cells to direct T-cell-mediated tumor lysis, its promising efficacy shown in the phase 2 DeLLphi-301 study, and the potential clinical benefits of combining it with durvalumab for maintenance therapy after platinum-based chemotherapy.

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.

Yoshiaki Nakamura, MD, PhD, discusses how the COSMOS-CRC-01 study demonstrated statistically significant recurrence-free intervals across various postoperative and adjuvant chemotherapy time points, highlighting the prognostic value of serial, tissue-free ctDNA assays for real-time detection of MRD vs single postchemotherapy assessments.

Saeed Sadeghi, MD, reviews real-world data on luspatercept, discussing treatment patterns and outcomes, including transfusion burden, hemoglobin increase, and other key baseline data that may differ from registrational studies in the context of managing lower-risk myelodysplastic syndromes (LR-MDS).

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.

Ticiana Leal, MD, discusses how in cases of extensive stage small cell lung cancer (ES-SCLC) that progress within 6 months of platinum-based chemotherapy, treatment options such as tarlatamab, lurbinectedin, topotecan, and irinotecan should be considered, alongside the potential to extend chemoimmunotherapy cycles. She also addresses the impact of National Comprehensive Cancer Network (NCCN) guidelines and the consideration of prophylactic cranial irradiation (PCI) despite negative brain imaging results.
