Nivolumab plus ipilimumab and chemotherapy continued to show durable benefit at 4 years compared with chemotherapy alone as first-line therapy in patients with advanced non–small cell lung cancer, particularly in the PD-L1–negative and squamous populations.

Fam-trastuzumab deruxtecan-nxki demonstrated clinically meaningful activity across a wide range of HER2 expressing solid tumors, including hard-to-treat tumors, according to findings from the phase 2 DESTINY-PanTumor02 trial.

The triplet combination of zotatifin, abemaciclib, and fulvestrant demonstrated a confirmed overall response rate of 21% in heavily pretreated patients with estrogen receptor–positive metastatic breast cancer.

Treatment with tovorafenib elicited encouraging and fast onset responses in heavily pretreated pediatric patients with low-grade glioma regardless of response assessment criteria, according to data from the phase 2 FIREFLY-1 trial that were presented at the 2023 ASCO Annual Meeting.

Kanwal P. S. Raghav, MBBS, MD, discusses primary findings from the phase 2 DESTINY-CRC02 trial (NCT04744831) of fam-trastuzumab deruxtecan-nxki (Enhertu) in patients with metastatic colorectal cancer with HER2 amplification or overexpression.

Neoadjuvant nivolumab plus chemotherapy improved clinical outcomes vs chemotherapy alone in patients with resectable non–small cell lung cancer who received definitive surgery with numerical but not statistical improvements seen even when definitive surgery was not achieved.

Treatment with the investigational gamma secretase inhibitor nirogacestat allowed patients with progressing desmoid tumors to experience a significant and clinically meaningful reduction in several aspects of disease-related pain when compared with placebo.

Findings from a subgroup analysis of the phase 3 EMERALD trial presented during the 2023 ASCO Annual Meeting demonstrated elacestrant elicited prolonged progression-free survival compared with standard-of-care therapy for patients with estrogen receptor-positive, HER2-negative non-detected ESR1 mutated breast cancer who experienced disease progression within 6 months of CDK4/6 inhibitor treatment plus endocrine therapy.

The PD-1 and TIGIT bispecific rilvegostomig demonstrated promising early signs of tolerability and efficacy in patients with advanced or metastatic PD-L1–positive non–small cell lung cancer following progression on at least 1 prior checkpoint inhibitor. according to initial findings from the phase 1/2 ARTEMIDE-01 study.
