Bispecific antibodies targeting programmed death 1 (PD-1) and vascular endothelial growth factor (PD1–VEGF) have shown promising efficacy in non-small-cell lung cancer (NSCLC). In our previous report of the HARMONi-6 study, we aimed to evaluate the efficacy and safety of ivonescimab plus chemotherapy versus tislelizumab plus chemotherapy as a first-line therapy for patients with advanced squamous NSCLC. Ivonescimab combined with chemotherapy significantly prolonged progression-free survival compared with tislelizumab plus chemotherapy. Here we report the prespecified interim overall survival analysis.
HARMONi-6 is a double-blind, randomised, phase 3 trial, which was conducted 50 hospitals across China. Patients aged 18–75 years with previously untreated, pathologically confirmed, unresectable stage IIIB, IIIC, or stage IV squamous NSCLC and an Eastern Cooperative Oncology Group performance status score of 0 or 1 were eligible for inclusion. Eligible patients were randomly assigned in a 1:1 ratio to receive ivonescimab or tislelizumab, in combination with paclitaxel and carboplatin for four cycles, followed by maintenance ivonescimab or tislelizumab monotherapy. The primary endpoint was progression-free survival assessed by the independent radiographic review committee as per Response Evaluation Criteria in Solid Tumours guidelines (version 1.1) in all randomly assigned patients. Overall survival was a key secondary endpoint; an interim analysis was planned when approximately 225 overall survival events were observed, but it was triggered after 204 overall survival events to meet regulatory deadlines. Safety, defined as adverse events and serious adverse events related to treatment, as well as adverse events related to immunity or VEGF blockade, were analysed in all randomly assigned patients who received least one dose of the assigned study treatment. This study is registered ClinicalTrials.gov (NCT05840016), has completed enrolment, and is ongoing for treatment and follow-up.
From Aug 17, 2023, to Jan 21, 2025, 761 patients were assessed for eligibility, and after 229 exclusions a total of 532 patients were randomly allocated (266 per group). 494 (93%) of patients were male and 38 (7%) of patients were female. The median age was 64 years (IQR 59–69). data cutoff (Feb 27, 2026), 204 deaths had occurred: 84 (32%) patients in the ivonescimab plus chemotherapy group and 120 (45%) in the tislelizumab plus chemotherapy group. With a median follow-up of 21·4 months (95% CI 20·27–21·91), the median overall survival was 27·9 months (95% CI 27·89–not evaluable [NE]) with ivonescimab versus 23·7 months (20·11–NE) with tislelizumab (hazard ratio for death 0·66 [95% CI 0·50–0·87]; pone-sided=0·0017), meeting the prespecified boundary (p
Ivonescimab plus chemotherapy demonstrated a statistically significant and clinically meaningful improvement in overall survival compared with tislelizumab plus chemotherapy in previously untreated patients with advanced squamous NSCLC. This regimen could provide a novel treatment option as first-line treatment in this patient group.
Median progression-free survival was significantly longer with sac-TMT plus pembrolizumab than with pembrolizumab alone (not reached vs 5·7 m) this is regardless of PDL-1 expression (1-49 or >50).
Confirmed objective response was 76% the median duration of response was 15.2 months and the median progression-free survival (PFS) was 14.4 months Of the patients with brain mets 47% had a confirmed intracranial objective response Zongertinib showed sustained efficacy in previously untreated patients with advanced or metastatic HER2-mutant Non–Small-Cell Lung Cancer (NSCLC) with mostly low-grade toxicity.
45 patients with Non–Small-Cell Lung Cancer (NSCLC) who received the 600-mg dose, 36% had a partial response, the median progression-free survival (PFS) was 8.3 months, estimated 12-month overall survival was 59% 21 patients with metastatic pancreatic ductal adenocarcinoma 24% had a response, the median PFS was 3.0 months and the median overall survival was 10.3 months.
Setidegrasib represents a meaningful advance in targeting KRAS G12D–mutant tumors, demonstrating a 36% response rate with median PFS exceeding 8 months in heavily pretreated NSCLC, and a 24% response rate with ~10 month median overall survival (OS) in third line pancreatic cancer, both notable signals in populations lacking approved targeted therapies.
The CHRYSALIS-2, the cohort C analysis of patients with atypical EGFR mutations showed meaningful and durable activity. Atypical mutations can be difficult to deal with as a clinician, and having concrete data on these (S768I, L861Q and G719ZX) mutations gives assurance that this doublet is active. Overall response rate (ORR) was 52% and median progression-free survival (PFS) was 11.1 months in refractory patients and 19.5 months in the treatment-naive population.
