Ticiana Leal, MD, discusses how lurbinectedin, a synthetic alkaloid derived from marine sources, exerts its antitumor effects by binding to DNA and disrupting repair mechanisms, highlighting promising efficacy results in the Phase 2 PMO1183 trial, where it achieved a 45% objective response rate (ORR) and an 11.2-month median overall survival in patients with relapsed small cell lung cancer (SCLC).

Joshua K. Sabari, MD, discusses the unique mechanism of action of B7-H3, highlighting its role as an immune checkpoint regulator that is overexpressed in SCLC and associated with poor prognosis. He notes that B7-H3 blockade can enhance CD8-positive T-cell activity and may serve as a promising treatment option for SCLC that has progressed after platinum-based chemotherapy.

Saeed Sadeghi, MD, shares his current approach to treating anemia in lower-risk myelodysplastic syndromes (LR-MDS), detailing when to choose erythropoiesis-stimulating agents (ESAs) for first-line treatment, conditions for switching therapies, and factors influencing the decision to use luspatercept as a first-line option, including considerations for dose escalation.

Yoshiaki Nakamura, MD, PhD, discusses the quantification threshold for tissue-free ctDNA in detecting residual tumor fractions, highlights additional mutations and hypermethylated loci identified by epigenomic assays, and examines how these assays complement current radiographic monitoring in stage II to III CRC while also considering their evolving role in identifying MRD to enhance recurrence-free survival.

Joshua K. Sabari, MD, discusses the anticipated clinical benefits of adding tarlatamab to durvalumab as maintenance therapy for patients with ES-SCLC, highlighting that statistically significant trial end points, such as improved PFS and OS, could encourage community oncologists to adopt this dual maintenance approach.

Ticiana Leal, MD, discusses how ifinatamab deruxtecan, a B7-H3 antibody-drug conjugate, targets the overexpressed B7-H3 in extensive-stage small cell lung cancer (ES-SCLC) to potentially enhance immune response and improve clinical outcomes, as highlighted by efficacy results from the Phase 1/ 2 IDeate-Lung02 study, which reported a 52.4% objective response rate and a 12.2-month overall survival (OS).
