Brief Summary
This is a single-arm study. The efficacy and safety of Disitamab Vedotin combined with Apalutamide and Toripalimab in the second-line treatment of HER2-expressing recurrent cervical cancer are evaluat...
Detailed Description
This study is a multicenter, open-label, single-arm, exploratory trial. It enrolls 33 participants with recurrent cervical cancer who have HER2 expression (IHC 1+, 2+, or 3+). After eligible participa...
Eligibility Criteria
Inclusion
- Voluntarily enroll in the study and sign a written informed consent form;
- Female patients aged 18 to 75 years (inclusive);
- Histologically or cytologically confirmed primary cervical squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, or small cell (neuroendocrine) cervical cancer;
- Progressive disease or recurrent disease after first-line treatment for recurrent cervical cancer;
- Subjects can provide tumor specimens (paraffin blocks, formalin-fixed paraffin-embedded \[FFPE\] sections, or fresh tissue sections) from the primary or metastatic site for HER2 detection, with HER2 immunohistochemistry (IHC) test results of IHC 1+, 2+, or 3+ (previous test results confirmed by the investigator are also acceptable);
- Presence of at least one evaluable lesion (per RECIST 1.1 criteria);
- Expected survival time ≥ 6 months;
- Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score of 0 to 1;
- For female patients of childbearing potential (i.e., premenopausal or not surgically sterilized), the serum pregnancy test result within 7 days before the first administration of the study drug must be negative; and reliable contraceptive measures must be used during the study drug administration period and within 60 days after the last dose;
- Normal function of major organs, meeting the following criteria:
- Left ventricular ejection fraction (LVEF) ≥ 50%; Hemoglobin (Hb) ≥ 9 g/dL; Absolute neutrophil count (ANC) ≥ 1.5 × 10⁹/L; Platelets (PLT) ≥ 100 × 10⁹/L; Serum total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN in the absence of liver metastasis, and ALT and AST ≤ 5 × ULN in the presence of liver metastasis; Serum creatinine (Scr) ≤ 1.5 × ULN, or creatinine clearance (CrCl) ≥ 40 mL/min calculated by the Cockcroft-Gault formula.
Exclusion
- History of malignant tumors other than cervical cancer, except for the following two situations:
- Patients who have received potentially curative treatment and have no evidence of the disease for 5 years;
- Basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, cervical carcinoma in situ, and other carcinoma in situ that have been successfully treated with resection;
- Previous allogeneic stem cell or solid organ transplantation;
- Previous systemic anti-tumor therapy (including traditional Chinese medicine with anti-tumor indications) completed less than 4 weeks before the first administration of the study drug, or patients whose adverse events caused by previous treatment have not recovered to ≤ Grade 1 according to the Common Terminology Criteria for Adverse Events (CTCAE) (except for alopecia and pigmentation);
- Vaccination with live vaccines within 4 weeks before the start of study drug administration, or planned receipt of any vaccines (except COVID-19 vaccines) during the study period;
- Previous or current history of congenital or acquired immunodeficiency diseases;
- Previous treatment with other antibody-drug conjugates (ADCs);
- Patients with known or suspected history of allergy to recombinant humanized anti-HER2 monoclonal antibody-MMAE conjugates and anti-PD-1 drugs of the same class, or history of hypersensitivity to chimeric/humanized antibodies or fusion proteins, or allergy to the excipients of the study drug;
- Other significant clinical and laboratory abnormalities that the investigator deems may affect safety evaluation, such as uncontrolled diabetes mellitus, chronic kidney disease, peripheral neuropathy of Grade 2 or higher (per CTCAE V5.0), abnormal thyroid function, etc.;
- Heart failure of New York Heart Association (NYHA) Class 3 or higher;
- Severe infection in active stage or with poor clinical control; active infections include:
- Positive for human immunodeficiency virus (HIV) (HIV1/2 antibodies);
- Active hepatitis B (positive for hepatitis B surface antigen \[HBsAg\], or hepatitis B virus deoxyribonucleic acid \[HBV DNA\] \> 2000 IU/ml with abnormal liver function);
- Active hepatitis C (positive for hepatitis C virus \[HCV\] antibodies, or HCV ribonucleic acid \[HCV RNA\] ≥ 10³ copies/ml with abnormal liver function);
- Active tuberculosis;
- Other uncontrolled active infections (Grade \> 2 per CTCAE V5.0); Unrecovered from surgery (e.g., presence of unhealed surgical incisions or severe postoperative complications);
- Other circumstances deemed unsuitable for enrollment by the investigator.
