Investigational Drug
Ivonescimab (AK112/SMT112) is a bispecific antibody studied primarily in advanced non-small-cell lung cancer (NSCLC). It has human phase 3 results, including trials comparing it with established immunotherapy or adding it to chemotherapy. The results apply to different patient groups and should not be treated as interchangeable. (pubmed.ncbi.nlm.nih.gov)
Ivonescimab targets both PD-1, an immune checkpoint, and VEGF-A, a protein involved in blood-vessel formation. It is designed to counter immune suppression and tumor angiogenesis simultaneously; whether this design provides a benefit depends on the clinical setting. (pmc.ncbi.nlm.nih.gov)
Grade 3 or higher treatment-related adverse events were more frequent with ivonescimab in some comparisons: 29% versus 16% with pembrolizumab in HARMONi-2, and 64% versus 54% with tislelizumab plus chemotherapy in HARMONi-6. In the global HARMONi trial, prominent grade 3–4 events included reduced blood-cell counts; treatment-related deaths occurred in both study groups. These rates come from different regimens and populations and cannot be directly compared across trials. (pubmed.ncbi.nlm.nih.gov)

Found 16 active trials using this drug:
TrialFetch AI summary: Adults with advanced or recurrent MET exon 14–skipping NSCLC receive tepotinib, a MET inhibitor, plus investigational ivonescimab, a bispecific antibody targeting PD-1 and VEGF-A. Prior MET inhibitors and checkpoint inhibitors are permitted; the study focuses on safety and identifying a tolerable tepotinib dose.
ClinicalTrials.gov ID: NCT07619339
TrialFetch AI summary: Adults with advanced or metastatic nonsquamous NSCLC harboring an EGFR sensitizing mutation or ALK, ROS1, RET, or NTRK fusion receive ivonescimab after genotype-appropriate targeted therapy and platinum/pemetrexed. A separate chemotherapy-naive cohort without EGFR-mutated disease receives ivonescimab plus carboplatin/pemetrexed after targeted therapy; ivonescimab is an investigational bispecific antibody targeting PD-1 and VEGF-A.
ClinicalTrials.gov ID: NCT07405190
TrialFetch AI summary: Adults with squamous or nonsquamous NSCLC, at least one SRS-eligible brain metastasis (1.0–3.5 cm), and ECOG performance status 0–1 receive chemotherapy plus ivonescimab, a bispecific antibody targeting PD-1 and VEGF-A, followed by three-fraction SRS. The study evaluates a tolerable ivonescimab dose and 3-month intracranial disease control.
ClinicalTrials.gov ID: NCT07535463
TrialFetch AI summary: Adults with metastatic NSCLC harboring an osimertinib-sensitive EGFR mutation who have progressed after a third-generation EGFR TKI and received platinum chemotherapy or are ineligible for it receive ivonescimab, a PD-1/VEGF-A bispecific antibody, plus either datopotamab deruxtecan, a TROP2-directed topoisomerase I inhibitor antibody–drug conjugate, or osimertinib.
ClinicalTrials.gov ID: NCT07535437
TrialFetch AI summary: Adults with unresectable or metastatic leiomyosarcoma and measurable disease are eligible after 1–3 prior systemic therapy lines, or if they declined standard first-line therapy; prior PD-1/PD-L1 or VEGF inhibitor treatment is excluded. Participants receive ivonescimab, an investigational bispecific antibody targeting PD-1 and VEGF-A, intravenously every 3 weeks.
ClinicalTrials.gov ID: NCT07516925
TrialFetch AI summary: Adults with ECOG 0–1 and advanced or metastatic RAS-mutant solid tumors are eligible; expansion cohorts include untreated nonsquamous NSCLC and previously treated solid tumors or colorectal cancer. Treatment pairs ivonescimab (PD-1/VEGF-A bispecific antibody) with a RAS(ON) inhibitor—daraxonrasib (multiple RAS variants), elironrasib (KRAS G12C), or zoldonrasib (KRAS G12D)—with selected cohorts adding platinum–pemetrexed, daraxonrasib, or cetuximab.
ClinicalTrials.gov ID: NCT07397338
TrialFetch AI summary: This trial enrolls patients with unresectable metastatic colorectal cancer who have ECOG performance status 0–1 and have not received systemic therapy for metastatic disease; MSI-H/dMMR and BRAF V600E–mutant disease are excluded. Patients receive mFOLFOX6 followed by fluorouracil/leucovorin maintenance, with either ivonescimab, a bispecific antibody targeting PD-1 and VEGF-A, or bevacizumab.
ClinicalTrials.gov ID: NCT07228832
TrialFetch AI summary: Adults with unresectable locally advanced or metastatic HER2-negative esophageal, gastroesophageal junction, or gastric adenocarcinoma who have not received treatment for advanced disease receive first-line ivonescimab plus FOLFOX. Ivonescimab is a bispecific antibody targeting PD-1 and VEGF-A; it is given alone for the first treatment, with FOLFOX added from cycle 2 onward.
ClinicalTrials.gov ID: NCT07070466
TrialFetch AI summary: Adults with previously treated metastatic colorectal adenocarcinoma receive ivonescimab, an investigational bispecific antibody targeting PD-1 and VEGF-A. Cohorts include dMMR/MSI-H disease progressing after PD-1/PD-L1 therapy and pMMR/MSS disease, with or without active liver metastases, progressing after or intolerant to fluoropyrimidine, irinotecan, and oxaliplatin.
