Study summary

This study is a prospective, multicenter, randomized, open controlled clinical trial aimed at evaluating the effectiveness and safety of serplulimab plus chemoradiotherapy in FIGO 2018 stage III or IVA cervical squamous cell carcinoma, adenocarcinoma, and adenosquamous cell carcinoma patients who have not received prior treatment.

Read the detailed description

Cervical cancer is the most prevalent malignant tumor of the female reproductive system in China, with an estimated 150,700 new cases and 55,700 new deaths annually. Concurrent chemoradiotherapy (CRT) remains the standard treatment for locally advanced cervical cancer (LACC). However, for high-risk LACC (HR-LACC) patients, the 2-year progression-free survival (PFS) rate is only 57%-62%, and the 5-year overall survival (OS) rate is 52%-64%, which are the leading causes of patient mortality. The KEYNOTE-A18 study demonstrated that the combination of pembrolizumab and CRT reduced the progression risk and death risk by 30% and 27%, respectively, for HR-LACC patients. Following this, the FDA approved pembrolizumab in combination with CRT for the treatment of newly diagnosed stages III-IVA cervical cancer in January 2024. This prospective, multicenter, randomized, controlled clinical trial study aims to evaluate the effectiveness and safety of serplulimab induced and combined chemoradiotherapy in FIGO 2018 stage III or IVA cervical squamous cell carcinoma, adenocarcinoma, and adenosquamous cell carcinoma patients who have not received prior treatment.

Study arms

  • Experimental
    Serplulimab + chemoradiotherapy , Serplulimab maintenance

    Participants receive serplulimab 300 mg intravenously (IV) on Day 1 of each 3-week cycle (Q3W) for 3 cycles followed by serplulimab 300 mg IV on Day 1 of each 6-week cycle (Q3W) for an additional 15 cycles. During the Q3W dosing period of serplulimab, participants receive concurrent chemoradiotherapy. The standard of care chemoradiotherapy regimen includes cisplatin 40 mg/m\^2 IV or carboplatin (AUC=2) once per week (QW) for 5 or 6 weeks plus external beam radiotherapy followed by brachytherapy not to exceed 8 weeks.

What researchers measure

Primary outcomes

  1. Progression-Free Survival(PFS) at Month 36

    PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. Per RECIST 1.1, or by histopathologic confirmation of suspected disease progression, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. Unequivocal progression of non-target lesions is also considered PD. PFS data will be cumulated to a certain cut-off date and the analysis will be performed via Kaplan-Meier approach to estimate the PFS rate at Month 36 using the entire PFS data up to the cut-off date.

    Time frame: Up to approximately 46 months.

Secondary outcomes

  1. Overall Survival (OS) at Month 36

    Overall Survival (OS) at Month 36 \[ Time Frame: Up to approximately 46 months \] OS, defined as the time from initiation of study treatment to death from any cause. OS data will be cumulated to a certain cut-off date and the analysis will be performed via Kaplan-Meier approach to estimate the OS rate at Month 36 using the entire OS data up to the cut-off date. The cut-off date is event-driven and estimated to be approximately 46 months.

    Time frame: Up to approximately 46 months

  2. Objective Response Rate (ORR)

    ORR is defined as the percentage of participants who have a Complete Response (CR: Disappearance of all target and non-target lesions and also includes reduction of all nodal lesions to \<10mm) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions and includes no unequivocal progression in non-target lesions) per RECIST 1.1.

    Time frame: Baseline up to approximately 36 months

  3. Complete Response Rate(CRR)

    The rate of CR (Disappearance of all target and non-target lesions and also includes reduction of all nodal lesions to \<10mm).

    Time frame: Baseline up to approximately 36 months

  4. Time to the first disease progression (TTP)

    Ddefined as the interval between the date of the initial medication and the time of imaging progression.

    Time frame: Up to approximately 24 months

  5. Duration of response (DOR)

    Duration of response is defined as the duration from the first documentation of objective response to the first documented disease progression or death due to any cause, whichever occurs first.

    Time frame: Up to approximately 24 months
