Brief Summary

The primary objective of this study is to evaluate the efficacy and safety of Iparomlimab and tuvonralimab (QL1706) in combination with platinum-based chemotherapy for cervical cancer neoadjuvant therapy. Additionally, the study aims to identify potential predictive biomarkers for therapeutic efficacy by analyzing tumor tissues and peripheral blood samples from participants receiving this combined treatment regimen.

Conditions

Cervical Cancer; Neoadjuvant Therapy

Keywords

immunotherapy; PD-1 Inhibitor; CTLA-4 Inhibitor

Outcome Measures

Primary Outcomes (1)

• CR/PR rate (%) in subjects with ≥1 response event

  The ORR assessment will include data obtained before surgery or until disease progression (whichever occurs first), or until the last evaluable assessment data before surgery if no disease progression has occurred.

  4 months after the patient was enrolled in the study

Secondary Outcomes (5)

• pCR rate (%) post neoadjuvant therapy

  6 months after the patient was enrolled in the study

• Time to first event post-neoadjuvant therapy

  2 years after the patient was enrolled in the study

• Patients whose residual active tumor cells are ≤ 10% after neoadjuvant therapy

  6 months after the patient was enrolled in the study

• Number of participants with treatment-related adverse events as assessed by CTCAE v5.0

  2 years after the patient was enrolled in the study

• Surgical Delay Rate (%)

  6 months after the patient was enrolled in the study

Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: female
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Voluntary signing of written Informed Consent Form (ICF).
• Age ≥18 years and ≤75 years at enrollment.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Histologically or cytologically confirmed cervical cancer (squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma) with clinical staging by FIGO 2018 criteria: IB3, IIA2, IIB, or IIIC (parametrial invasion without reaching the pelvic wall, no vaginal lower third involvement).
• No prior systemic or local antitumor therapy (including radiotherapy, chemotherapy, immunotherapy, biologics, or small-molecule targeted therapy) for cervical cancer prior to the first dose of study treatment.
• Agreement to undergo radical hysterectomy with no surgical contraindications as judged by the investigator.
• At least one untreated measurable lesion according to RECIST v1.1.
• Consent to provide tumor tissue and peripheral blood samples during the screening period and study procedures for related research.
• Adequate organ function:
• a) Hematology (no blood components or growth factor support within 7 days before study treatment): i. Absolute neutrophil count (ANC) ≥1.5×10⁹/L (1,500/mm³); ii. Platelet count ≥100×10⁹/L (100,000/mm³); iii. Hemoglobin ≥90 g/L. b) Renal: i. Calculated creatinine clearance (CrCl) ≥50 mL/min (Cockcroft-Gault formula); ii. Urine protein \<2+ or 24-hour urine protein \<1.0 g. c) Hepatic: i. Total bilirubin (TBil) ≤1.5×ULN; ii. AST and ALT ≤2.5×ULN; iii. Albumin (ALB) ≥28 g/L. d) Coagulation: i. INR and APTT ≤1.5×ULN (stable anticoagulation therapy allowed if parameters remain within therapeutic range).
• e) Cardiac: i. Left ventricular ejection fraction (LVEF) ≥50%.
• Fertile women must have a negative urine or serum pregnancy test within 3 days before first dose. If urine test is inconclusive, serum testing is required. Contraception must be used from screening until 120 days post-treatment. Barrier methods or hormonal contraceptives (e.g., pills) are required.
• Fertile women: Not surgically sterilized (e.g., bilateral tubal ligation) or premenopausal (≥12 months amenorrhea with FSH in postmenopausal range).
• Effective contraception: Methods with \<1% failure rate (e.g., hormonal contraceptives).
• Willingness and ability to comply with scheduled visits, protocols, labs, and study requirements.

You may not qualify if:

• Histopathological type other than cervical squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma (e.g., small cell carcinoma, clear cell carcinoma, sarcoma).
• History of other malignancies within 3 years prior to enrollment, excluding localized malignancies cured by local therapy (e.g., basal cell carcinoma, squamous cell carcinoma of the skin, or ductal carcinoma in situ of the breast).
• Simultaneous enrollment in another clinical study, unless it is an observational, non-interventional study or within the follow-up period of an interventional study.
• Non-specific immunomodulatory therapy (e.g., interleukins, interferons, thymosin, tumor necrosis factor) within 2 weeks prior to first dose; herbal or proprietary Chinese medicine with antitumor indications within 1 week prior to first dose.
• Active autoimmune disease requiring systemic therapy (e.g., disease-modifying agents, corticosteroids, immunosuppressants) within the past 2 years. Replacement therapy (e.g., thyroid hormone, insulin, or physiological corticosteroids for adrenal/pituitary insufficiency) is not considered systemic therapy.
• History of non-infectious pneumonia requiring systemic corticosteroids or current interstitial lung disease.
• Significant bleeding diathesis or coagulation dysfunction.
• Uncontrolled comorbidities, including but not limited to decompensated cirrhosis, nephrotic syndrome, uncontrolled metabolic disorders, severe active peptic ulcer disease/gastritis, or psychiatric/social conditions impairing compliance or informed consent.
• History of myocarditis, cardiomyopathy, or malignant arrhythmias. Within 12 months prior to first dose: unstable angina, congestive heart failure, or vascular disease requiring hospitalization (e.g., surgical repair of aortic aneurysm/peripheral venous thrombosis). Within 6 months prior: esophageal-gastric varices, unhealed wounds, gastrointestinal perforation, fistula, obstruction, intra-abdominal abscess, or acute gastrointestinal bleeding. Arterial thromboembolism, NCI CTCAE 5.0 grade ≥3 venous thromboembolism, transient ischemic attack, stroke, hypertensive crisis, or hypertensive encephalopathy. Within 1 month prior: acute exacerbation of COPD. Current hypertension uncontrolled with oral antihypertensives (SBP ≥160 mmHg or DBP ≥100 mmHg).
• Active or history of definite inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis, or chronic diarrhea).
• Severe infection within 4 weeks prior to first dose (including hospitalization, sepsis, or severe pneumonia). Active infection requiring systemic antimicrobial therapy within 10 days prior (excluding HBV/HCV antiviral therapy).
• Major surgery or severe trauma within 30 days prior to first dose; minor local procedures (excluding peripherally inserted central catheter placement) within 3 days prior.
• History of immunodeficiency, HIV seropositivity, or current long-term systemic corticosteroid/immunosuppressant use.
• Active syphilis infection.
• History of allogeneic organ or hematopoietic stem cell transplantation.
