Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

1. The subject voluntarily participates in this clinical study, has provided signed informed consent prior to the initiation of any screening procedures, and is able to understand and comply with the study requirements.
2. Aged 18 to 75 years (inclusive, calculated on the day of signing the informed consent form).
3. Histologically or cytologically confirmed cervical cancer, including squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma.

4. Not eligible for curative treatment with surgery, radiotherapy, or chemoradiotherapy.

   Willing to undergo a biopsy during the screening period to provide fresh tumor tissue for PD-L1 and PIK3CA mutation testing; if a biopsy is not feasible, archived tumor tissue samples (formalin-fixed, paraffin-embedded (FFPE) blocks or unstained FFPE slides) may be provided for PD-L1 testing. All testing will be performed at a central laboratory. If the provided tumor tissue sample is deemed unsuitable by the central laboratory for evaluating PD-L1 expression and/or PIK3CA mutation status, the subject cannot be enrolled.

5. Must have at least one measurable lesion as per RECIST v1.1 criteria. Previously irradiated lesions with confirmed progression on imaging may be considered as target lesions.
6. ECOG performance status of 0 or 1.
7. Able to swallow tablets normally.
8. Life expectancy of ≥3 months.

Exclusion Criteria:

1. Previous treatment with any PI3K, AKT, or mTOR inhibitor, or prior treatment with toripalimab.
2. Patients with type 1 or type 2 diabetes mellitus.
3. History of interstitial lung disease, drug-induced pneumonitis, pulmonary fibrosis, pneumoconiosis, or radiation pneumonitis (patients with only radiographic evidence of radiation pneumonitis and not requiring corticosteroid therapy may be enrolled). Patients with active pneumonia during screening, severely impaired lung function, or other conditions that may interfere with the detection and management of suspected drug-related pulmonary toxicity.
4. Radiographic evidence of tumor invasion into the bladder or rectum, deemed by the investigator to pose a risk of perforation; or a known history of female reproductive tract fistula (e.g., vesicovaginal fistula, urethrovaginal fistula, cervicovesical fistula, etc.). Patients may be enrolled if the perforation or fistula has been treated with diversion surgery, resection, or repair, and the condition is considered resolved or controlled by the investigator.
5. Currently active bleeding, intra-abdominal abscess, or intestinal obstruction requiring clinical intervention.
6. CT/MRI or other imaging shows tumor invasion or encasement of major blood vessels, indicating a high risk of bleeding.
7. Current clinically significant hydronephrosis. Patients may be enrolled if hydronephrosis is relieved by nephrostomy or ureteral stent placement.
8. Patients with refractory nausea and vomiting, dysphagia, gastrointestinal disorders affecting drug absorption (e.g., Crohn's disease, ulcerative colitis, or short bowel syndrome), or other malabsorption conditions.
9. History of severe allergy, hypersensitivity, or other anaphylactic reactions to the investigational product or any of its excipients.
10. Administration of a live vaccine within 4 weeks prior to randomization or planned administration during the study.
11. Patients with active autoimmune disease, history of bone marrow or solid organ transplantation, suicidal tendency, alcohol or drug dependence, clear history of neurological or psychiatric disorders, or other conditions that, in the investigator's assessment, may contraindicate the use of the investigational product, compromise the interpretation of study results, or result in forced discontinuation from the study.

• Allocation: Randomized
• Interventional Model: Parallel Assignment
• Masking: None (Open Label)

Number of Arms

2

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Investigator's Choice of Chemotherapy	Drug: Investigator's Choice of Chemotherapy; Randomization for these two strata will be closed upon reaching the total enrollment of 310 subjects who are immunotherapy-naïve or have tumors with PIK3CA wild-type status confirmed by the central laboratory.
Experimental: WX390 1.1mg + Toripalimab 240mg; Participants will receive WX390 continuous oral dosing (1.1 mg once a day) and Toripalimab fixed dose (240mg, intravenous, Day 1, every 3 weeks).	Drug: WX390 1.1mg + Toripalimab 240mg; Participants will receive WX390 continuous oral dosing (1.1 mg once a day) and Toripalimab fixed dose (240mg, intravenous, Day 1, every 3 weeks).
