Summary

Purpose:

To evaluate the efficacy and safety of neoadjuvant treatment with iparomlimab and tuvonralimab (QL1706), a dual PD1and CTLA4 bispecific antibody, in combination with paclitaxel and either cisplatin or carboplatin (TP/TC regimen) for patients with locally advanced cervical cancer.

Eligibility Criteria:

Women aged 18 to 70 years with newly diagnosed, histologically confirmed cervical cancer (squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma), FIGO stage IB3 or IIA2, with no evidence of significant lymph node involvement (pelvic and paraaortic lymph nodes \<1.5 cm in short diameter), and who have not received any prior anticancer therapy.

Study Procedures:

Participants will receive up to 4 cycles of QL1706 plus TP/TC chemotherapy (once every 3 weeks) prior to surgery. After 2 cycles, clinical assessment will be performed to evaluate tumor response. If tumor shrinkage is observed, treatment may continue for 2 additional cycles, followed by imaging evaluation. Depending on the response, participants with complete or partial response may undergo less extensive surgery (cervical conization plus sentinel lymph node biopsy) rather than standard radical hysterectomy. After surgery, participants who achieve a major pathological response will receive QL1706 maintenance therapy as a single agent for up to 8 additional cycles (once every 3 weeks). For participants with insufficient tumor response, standard radical hysterectomy will be performed. Postoperative adjuvant therapy (radiation or chemotherapy) will follow standard clinical guidelines.

Primary and Secondary Objectives:

The primary endpoint is the pathological complete response (pCR) rate in the resected tissue following neoadjuvant treatment. Secondary endpoints include safety (treatment related adverse events), objective response rate (ORR), 3 years overall survival, 3 years disease free survival, and quality of life.

Study Duration:

Total participation time depends on treatment response and surgical scheduling, with an expected duration of approximately 9 to 12 months (including neoadjuvant treatment, surgery, and potential maintenance therapy).

Conditions

  • Uterine Cervical Neoplasms
  • Locally Advanced

Interventions

DRUG

Carboplatin

AUC=5 administered intravenously over at least 1 hour on Day 1 of each 21-day cycle for up to 4 cycles. Cisplatin or Carboplatin according to investigator's choice

DRUG

Iparomlimab and Tuvonralimab (QL1706)

250 mg administered intravenously over at least 30 minutes on Day 1 of each 21-day cycle for up to 4 cycles as neoadjuvant therapy, and up to 8 cycles as maintenance therapy (for patients achieving optimal pathological response).

DRUG

Paclitaxel

150-175 mg/m² administered intravenously over at least 3 hours on Day 1 of each 21-day cycle for up to 4 cycles, with standard premedication to prevent hypersensitivity.

DRUG

Cisplatin

70-75 mg/m² administered intravenously over at least 1 hour, split over two consecutive days (Day 1 and Day 2) of each 21-day cycle for up to 4 cycles. Cisplatin or Carboplatin according to investigator's choice
