Safety and Efficacy Study of NWRD09 in HPV-16 Related Intraepithelial Neoplasia and Cervical Cancer Patients
This is a single-arm, open label, two cohorts, multi-center clinical study to evaluate the safety and efficacy of HPV-16 targeted mRNA vaccine (NWRD09) in HPV-16 related Cervical, vaginal, and vulvar intraepithelial neoplasia (LSIL and HSIL) patients (cohort A) and HPV-16 related cervical cancer patients (cohort B).
∙ Patients had to meet all of the following inclusion criteria:
• Women aged between 18 and 60 years.
• HPV16 is positive during the screening period.
• Histologically confirmed HPV-16-associated cervical, vaginal, and vulvar intraepithelial neoplasia (LSIL and HSIL). In the case of LSIL, it is necessary to meet persistent HPV16 infection for more than 6 months. In the case of HSIL, it is necessary to meet the requirements of satisfactory colposcopy at screening, which is defined as the squamous columnar epithelial junction (class I or class II transformation zone) is fully visible, and the upper limit of the white epithelium acetate or suspected CIN lesions are fully visible.
• Eligible subjects of childbearing potential must agree to use a reliable method of contraception (hormonal or barrier method or abstinence, etc.) with their partner for the duration of the trial or for at least 6 months after the last dose. For premenopausal women with the possibility of childbearing, blood pregnancy tests must be negative within 7 days prior to the first use of the NWRD09.
• Have fully understood the study and voluntarily signed the ICF, have good communication with the investigator, and are able to complete all treatments, examinations, and visits stipulated in the study protocol.
∙ Patients had to meet all of the following inclusion criteria:
• Women aged ≥ 18 years.
• HPV16-related recurrent or metastatic advanced cervical cancer (Histologically confirmed squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma) patients who have progressed after at least one lines of standard therapy or are intolerant to toxic side effects, or for which there is no standard treatment at present (Treatment failure refers to: disease progression during or after treatment with systemic antineoplastic regimens; Intolerance refers to: the patient has grade 3-4 adverse reactions after receiving standard therapy, and the patient refuses to continue the original treatment).
• At least 1 measurable lesion (RECIST 1.1). Tumor lesions that have received prior radiotherapy or other local therapy are considered measurable only if disease progression at the treatment site is clearly documented after completion of treatment.
• Eastern Cooperative Oncology Group (ECOG) Performance status of 0 or 1.
• Had recovered from all toxicities related to prior anticancer therapies to grade≤1 or baseline level as defined by CTCAE v5.0 (except for the asymptomatic laboratory examination abnormalities such as elevated ALP, hyperuricemia, elevated serum amylase/lipase, elevated blood glucose, etc., and toxicities judged by the investigator to have no safety risk, such as alopecia, grade 2 peripheral neurotoxicity, and hypothyroidism stabilized by hormone replacement therapy, etc.).
• Major organ functions must meet the following criteria:
‣ Blood routine: absolute neutrophil count (ANC) ≥ 1.5×10\^9/L, platelet count ≥ 80×10\^9/L, hemoglobin ≥ 90 g/L,
⁃ Liver function: total bilirubin (TBIL) ≤ 1.5 ULN (≤ 3 ULN for Gilbert's syndrome, liver cancer, or liver metastases), AST and ALT ≤ 2.5 ULN for subjects without liver metastases, and ≤ 5.0 ULN for subjects with liver metastases,
⁃ Renal function: creatinine (Cr) ≤ 1.5 ULN, or creatinine clearance (Ccr) ≥ 50 mL/min (using the Cockcroft and Gault formula),
⁃ Coagulation function: international normalized ratio (INR) ≤ 1.5, and activated partial thromboplastin time (APTT) ≤ 1.5 ULN.
• Has life expectancy of at least 3 months in the best judgement of the investigator.
• Eligible subjects of childbearing potential must agree to use a reliable method of contraception (hormonal or barrier method or abstinence, etc.) with their partner for the duration of the trial or for at least 6 months after the last dose. For premenopausal women with the possibility of childbearing, blood pregnancy tests must be negative within 7 days prior to the first use of the NWRD09.
• Have fully understood the study and voluntarily signed the ICF, have good communication with the investigator, and are able to complete all treatments, examinations, and visits stipulated in the study protocol.
