Ivonescimab Monotherapy or in Combination With Chemotherapy as Neoadjuvant/Adjuvant Therapy for Resectable Non-small Cell Lung Cancer

November 18, 2025 updated by: Wu Nan, Peking University Cancer Hospital & Institute

Evaluate the Efficacy and Safety of Ivonescimab Monotherapy or in Combination With Chemotherapy as Neoadjuvant/Adjuvant Therapy for Resectable Non-small Cell Lung Cancer

This study is a prospective, II Phase clinical trial designed to evaluate the efficacy and safety of ivonescimab as monotherapy or in combination with platinum-based chemotherapy in the perioperative treatment of resectable non-small cell lung cancer (NSCLC).

Patients are stratified by PD-L1 expression level (TPS ≥50% vs. <50%) and randomized in a 2:1 ratio to differentiated neoadjuvant treatment arms: PD-L1≥50% subgroup: Ivonescimab monotherapy (4 cycles) vs. ivonescimab + platinum-based chemotherapy (4 cycles); PD-L1<50% subgroup: Ivonescimab + 1 cycle of chemotherapy followed by 3 cycles of monotherapy vs. ivonescimab + platinum-based chemotherapy (4 cycles). All patients subsequently receive 13 cycles of ivonescimab as adjuvant maintenance therapy postoperatively.

As the first study to explore a PD-L1-directed chemotherapy de-escalation strategy, this trial aims to reduce treatment toxicity while maintaining efficacy, thereby providing a novel personalized precision therapy pathway for resectable NSCLC.

  2. Presence of locally advanced unresectable or metastatic disease;
  3. Palliative local treatment for non-target lesions within 2 weeks before the first administration; receipt of non-specific immunomodulatory therapy (such as interleukin, interferon, thymosin, tumor necrosis factor, etc., excluding IL-11 used for the treatment of thrombocytopenia) within 2 weeks before the first administration; receipt of Chinese herbal medicines or proprietary Chinese medicines with anti-tumor indications within 1 week before the first administration.

Time Frame
Pathological Complete Response(pCR)rate
Time Frame: At the time of postoperative pathological assessment,Up to approximately 2 years
pCR is defined as the proportion of subjects who have completed surgery and, after the completion of neoadjuvant therapy, have no residual tumor in the resected primary tumor site and lymph nodes as evaluated by local pathology experts.
At the time of postoperative pathological assessment,Up to approximately 2 years

Outcome Measure
Measure Description

MPR is defined as the proportion of patients who have completed surgery and, as evaluated by local pathology experts, have residual viable tumor cells accounting for ≤10% in the resected primary tumor foci and lymph nodes.
At the time of postoperative pathological assessment,Up to approximately 2 years
R0 resection rate
Time Frame: At the time of postoperative pathological assessment,Up to approximately 2 years
