What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 40 participants in total. It began in 2025-06-25 with a primary completion date of 2027-05-05.

Brief Summary

This is a Phase II, open-labeled, single-arm, study of neoadjuvant BL-B01D1in combination with Almonertinib followed by adjuvant Almonertinib for the treatment of Patients with EGFR-Mutation Positive Stage II-IIIB Resectable Non-Small Cell Lung Cancer.

Eligibility Criteria

Inclusion Criteria: 1. Voluntarily sign the informed consent form and comply with the study protocol requirements. 2. Male or female, Age ≥18 years and ≤75 years at the time of signing the informed consent form. 3. Diagnosed with stage II-IIIB (according to Version 8 of TNM staging) EGFR-sensitive mutation-positive non-small cell lung cancer (NSCLC) with feasibility or potential feasibility for radical surgery (radical lobectomy + systematic lymph node dissection), and assessed by the investigator as requiring neoadjuvant therapy. 4. Adequate pulmonary function to tolerate surgery. 5. Must have at least one measurable lesion per RECIST v1.1 criteria. 6. Eastern Cooperative Oncology Group (ECOG) performance status score of ≤1. 7. No severe cardiac dysfunction, with left ventricular ejection fraction (LVEF) ≥50%. 8. Organ function levels must meet the following criteria: 1. Bone marrow function: Absolute neutrophil count (ANC) ≥1.5×10⁹/L, platelet count ≥100×10⁹/L, hemoglobin ≥90 g/L; 2. Hepatic function: Total bilirubin (TBIL) ≤1.5×ULN, AST and ALT ≤2.5×ULN; 3.

Coagulation function: International normalized ratio (INR) ≤1.5 and activated partial thromboplastin time (APTT) ≤1.5×ULN. 10. Urine protein: ≤2+ on dipstick or ≤1000 mg/24h. 11. Contraception: Females of childbearing potential or males with partners of childbearing potential must use highly effective contraception from 7 days before the first dose until 6 months after the last dose. Females of childbearing potential must have a negative serum pregnancy test within 7 days prior to the first dose. Exclusion Criteria: 1. Patients who have received previous systemic or local anti-tumor therapy for non-small-cell lung cancer. 2. Patients with other malignant tumors within 5 years before the first administration, except those who have been cured skin squamous cell carcinoma, basal cell carcinoma, superficial bladder cancer, prostate/cervix/breast cancer in situ and so on are considered to be eligible for enrollment. 3. Major surgery (investigator-defined) within 4 weeks before the first dose. 4. Current interstitial lung disease, drug-induced interstitial pneumonia, radiation pneumonitis requiring steroid therapy, or a history of these diseases. 5. Severe systemic infection occurred within 4 weeks before screening, including but not limited to severe pneumonia caused by fungi, bacteria, viruses, bacteremia, or serious infectious complications. 6. Patients at risk for active autoimmune disease, or with a history of autoimmune disease, Including but not limited to Crohn's disease, ulcerative colitis, systemic lupus erythematosus, sarcoidosis, Wegener syndrome, autoimmune hepatitis, systemic sclerosis, Hashimoto's thyroiditis, autoimmune vasculitis, autoimmune neuropathy (Guillain-Barre syndrome), etc. Exceptions include type I diabetes mellitus, hypothyroidism that is stable with hormone-replacement therapy (including that due to autoimmune thyroiditis), psoriasis or vitiligo that does not require systemic treatment, and hypothyroidism that is stable with hormone-replacement therapy. 7. Human immunodeficiency virus antibody (HIVAb) positive, active tuberculosis, active hepatitis B virus infection (HBsAg positive or HBcAb positive and HBV-DNA copy number \> central detection lower limit) or hepatitis C virus infection (HCV antibody positive and HCV-RNA\> central detection lower limit). 8. Poorly controlled hypertension (systolic blood pressure \>150 mmHg or diastolic blood pressure \>100 mmHg). 9. A history of severe cardiovascular and cerebrovascular diseases, including but not limited to: 1. severe cardiac rhythm or conduction abnormalities, such as ventricular arrhythmia requiring clinical intervention, degree III atrioventricular block, complete left bundle branch block, frequent and uncontrollable arrhythmias, such as atrial fibrillation, atrial flutter, ventricular fibrillation, and ventricular flutter (except transient); h) prolonged QT interval (QTc\>450 msec in men or QTc\>470 msec in women) at rest (except transient); 2. acute coronary syndrome, congestive heart failure, aortic dissection, stroke, or other grade 3 or higher cardiovascular or cerebrovascular event occurring within 6 months before the first dose; 3. patients with New York Heart Association (NYHA) functional class ≥II heart failure; 4. unstable angina pectoris; 5. Patients with a history of cerebral infarction or cerebral hemorrhage within 6 months; 10. Previous history of allogeneic stem cell, bone marrow or organ transplantation. 11. Patients with a history of allergy to recombinant humanized antibodies or to BL-B01D1 or any excipients of Almonertinib Mesylate Tablets. 12. A history of autologous or allogeneic stem cell transplantation. 13. Pregnant or lactating women. 14. Other circumstances considered by the investigator to be inappropriate for participation in the trial.
