Outcome Measures

Primary Outcomes (1)

  • Objective response rate (ORR) by RECIST1.1 in relapsed or metastatic uterine cervical cancer evaluated by IRC (Independent Review Committee), confirmation of CR and PR is required in at least 4 weeks after initial documentation.

    To investigate the efficacy of SG001 in relapsed or metastatic uterine cervical cancer.

    From first dose to the first documented progression of disease, subject withdrawal, lose to follow-up, death, initiating a subsequent cancer therapy, or study completion or termination, whichever occurs earliest, assessed up to 24 months.

Secondary Outcomes (10)

  • ORR (objective response rate) evaluated by investigators.

    From first dose to the first documented progression of disease, subject withdrawal, lose to follow-up, death, initiating a subsequent cancer therapy, or study completion or termination, whichever occurs earliest, assessed up to 24 months.

  • DOR (duration of response) evaluated by IRC.

    From first dose to the first documented progression of disease, subject withdrawal, lose to follow-up, death, initiating a subsequent cancer therapy, or study completion or termination, whichever occurs earliest, assessed up to 24 months.

  • DCR (disease control rate) evaluated by IRC.

    From first dose to the first documented progression of disease, subject withdrawal, lose to follow-up, death, initiating a subsequent cancer therapy, or study completion or termination, whichever occurs earliest, assessed up to 24 months.

  • PFS (free-progression survival) evaluated by IRC.

    From first dose to the first documented progression of disease, subject withdrawal, lose to follow-up, death, initiating a subsequent cancer therapy, or study completion or termination, whichever occurs earliest, assessed up to 24 months.

  • OS (overall survival) evaluated by IRC.

    From first dose to the first documented progression of disease, subject withdrawal, lose to follow-up, death, initiating a subsequent cancer therapy, or study completion or termination, whichever occurs earliest, assessed up to 24 months.

Study Arms (1)

SG001

EXPERIMENTAL

Recombinant Human Anti-PD-1 Monoclonal Antibody

Drug: SG001

Interventions

SG001DRUG

Subjects will receive intravenous infusion of SG001 at the dose of 240 mg every 2 weeks until disease progression, unacceptable toxicity, meeting the suspension or termination criteria, or up to 24 months in patients without disease progression.

Also known as: Recombinant Human Anti-PD-1 Monoclonal Antibody
SG001

Eligibility Criteria

Age18 Years+
Sexfemale(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \. Age ≥ 18 on the day of signing informed consent and volunteered to participated in this study.
  • \. Histologically documented relapsed or metastatic uterine cervical cancer including squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma, a relevant pathological report must also be provided.
  • \. Relapsed or metastatic uterine cervical cancer patient who has failed at least first line platinum-based chemotherapy, which means having disease progression during or following at least first line platinum based chemotherapy or for which platinum based chemotherapy is not tolerated, having disease progression within 6 months of or during neoadjuvant or adjuvant treatment with platinum based chemotherapy can also be accepted.
  • \. Programmed Cell Death Ligand 1 (PD-L1) positive expression defined by Combined Positive Score (CPS) ≥1.
  • \. All the subjects should have at least one measurable lesion in CT or MRI test assessed by RECIST 1.1. A previously irradiated site lesion could only be counted as a target lesion if there was clear sign of progression since the irradiation.
  • \. If subjects have received anti-tumor therapies before, the toxicity severity must decrease to ≤ Grade1 evaluated by NCI-CTCAE 5.0, except for residual alopecia or fatigue.
  • \. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • \. Has a predicted survival period ≥ 3 months assessed by investigators.
  • \. Demonstrate adequate organ function as defined below:
  • Blood routine tests (No blood transfusions were performed, no hematopoietic stimulators were used, and no drugs were used to correct blood cell counts ): Absolute neutrophil count (ANC) ≥1.5×109/L; Platelets ≥75×109/L; Hemoglobin (HGB)≥9 g/dL;
  • Serum biochemical indexs: Serum creatinine ≤1.5 X ULN or Creatinine clearance (CCr) ≥ 50mL/min; Serum total bilirubin (TBIL) ≤ 1.5 X upper limit of normal ULN (Subjects with Gilbert's syndrome can be up to 3 x ULN); Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 X ULN or ≤5 X ULN for subjects with hepatocellular carcinoma and liver metastases;
  • Coagulation function: Activated partial thromboplastin time (APPT) and International Normalized Ratio (INR)≤1.5 X ULN (No anticoagulants or other drugs affecting clotting function were used within 14 days prior to the first administration, except for subjects requiring long-term anticoagulant therapy).
  • \. Women of child-bearing potential (WOCBP) should be willing to use reliable contraceptive methods from signing the informed consent form to 6 months after last dose of investigational drug.

You may not qualify if:

  • \. History of allergic reactions attributed to any monoclonal antibody, and uncontrolled history of allergic asthma.
  • \. Patients with other types of malignant tumours that have progressed or require treatment within 5 years prior to the screening, but well-treated skin basal cell carcinoma, skin squamous cell carcinoma, or superficial bladder cancer, and having cured carcinoma in situ, e.g. breast carcinoma in situ, can be accepted.
  • \. Patients with any active autoimmune disease, but subjects with following diseases are allowed for further screening: subjects with well-controlled type I diabetes, well-controlled hypothyroidism with hormone replacement therapy, skin diseases (such as vitiligo, psoriasis, or hair loss) without systemic treatment, or who are not expected to relapse without external triggers.
  • \. History of primary immunodeficiency.
  • \. Patients with serious cardiovascular diseases, such as grade 2 or above heart failure based on the NYHA (New York Heart Association) Class guidelines, previous myocardial infarction within 3 months, poorly controlled arrhythmias or unstable angina pectoris, previous arterial or venous thrombosis events within 3 months (e.g. transient ischemic attack, cerebral hemorrhage, cerebral infarction, deep vein thrombosis and pulmonary embolism).
  • \. Has history of Interstitial Lung Disease (Patients caused by radiotherapy are eligible), or non-infectious pneumonitis need for glucocorticoid therapy.
  • \. Have a history of active tuberculosis.
  • \. Subjects with untreated or treated but still symptomatic central nervous system metastases (except for residual signs or symptoms related to CNS treatment, those with stable or improved neurological symptoms at least 2 weeks prior to screening can be included).
  • \. Prior therapy with any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways including anti-PD-1, anti-PD-L1, anti CTLA-4, OX40 agonist, and anti-CD137, etc.
  • \. Immune-related adverse events of grade 3 or higher(NCI-CTCAE 5.0)after immune therapy.
  • \. Have received major surgery or radical radiotherapy within 28 days, or palliative radiotherapy within 14 days, or radiological agents (strontium, samarium, etc.) within 56 days prior to screening.
  • \. Have received systemic anti-tumour therapy 28 days before the first dose, including but not limited to chemotherapy, immunotherapy, macromolecular targeted therapy, and biological therapy (tumour vaccine, cytokines or growth factors controlling cancer); Patients who received small-molecule targeted and oral fluorouracil therapy within 14 days before the first dose.
  • \. Have received attenuated live vaccine within 28 days before the first dose or planned to receive during the study period.
  • \. Have received Chinese herbal medicine or Chinese patent medicine with anti-tumor activity within14 days prior to the first dose.
