About this study

Ovarian cancer is a cancer that forms in or on an ovary. The majority of ovarian cancers arise from the epithelium (outer lining) of the ovary. In 2015 it was reported found in 1.2 million women and resulted in 161,100 deaths worldwide. Among women it is the seventh-most common cancer and the eighth-most common cause of death from cancer. Treatment for ovarian cancer consists of surgery, chemotherapy, immunotherapy and sometimes, radiotherapy. The kind of treatment depends on many factors, including the type of ovarian cancer, its stage and grade, as well as the general health of the patient.

Adoptive immunotherapy with cytotoxic T lymphocytes (CTLs) reactive with specific viral antigens has proven to be effective. Here, the investigators aim to evaluate the safety and efficacy of multiple infusions of ovarian cancer specific cytotoxic T lymphocytes in patients.

Inclusion criteria

  • Written, informed consent obtained prior to any study-specific procedures.
  • Age older than 10 years.
  • Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1.
  • Expected survival ≥ 12 weeks.
  • Histologically confirmed and documented high risk International Federation of Gynecology and Obstetrics (FIGO): Stage II-IV.
  • Not pregnant, and on appropriate birth control if of childbearing potential.
  • Initial hematopoietic reconstitution with
  • neutrophils (ANC) ≥ 1,000/mm^3;
  • platelet (PLT) ≥ 100,000/mm^3.
  • Proper renal and hepatic functions (ULN denotes "upper limit of normal range") with
  • serum creatinine ≤ 2×ULN;
  • serum bilirubin ≤ 2×ULN;
  • AST/ALT ≤ 2×ULN;
  • ALKP ≤ 5×ULN;
  • serum bilirubin. 2.0 is acceptable in the setting of known Gilbert's syndrome.
  • Human immunodeficiency virus (HIV) and Hepatitis C virus (HCV) test were negative.

Exclusion criteria

  • Patients with ovarian tumors with low malignant potential (i.e. borderline tumors);
  • Patients with evidence of abdominal free air not explained by paracentesis or recent surgical procedure (prior, current or planned treatment).
  • Previous treatment of adoptive T cell therapy.
  • Current or recent treatment (within the 28-day period prior to Day 0) with another investigational drug
  • Minor surgical procedures within 2 days prior to Day 0 (including central venous access device placement for chemotherapy administration, tumor biopsies, needle aspirations).
  • Pregnant or lactating females.
  • Inadequate bone marrow function with
  • absolute neutrophil count < 1,000/mm^3;

  • alkaline phosphatase > 2.5 x ULN;
  • serum creatinine >2.0 mg/dl (> 177 μmol/L);
  • urine dipstick for protein uria should be < 2+. Patients with ≥ 2+ proteinuria on dipstick urinalysis at baseline should undergo 24 hour urine collection and must demonstrate < 1 g of protein/24 hr.

  • Subject infected with HCV (HCV antibody positive), HBV (HBsAg positive), and HIV (HIV antibody positive),Treponema pallidum antibody positive or TB culture positive.

Treatment and study plan

OC-CTLs

Biological

2 to 4 infusions, once a week, for 1x10^5~4x10^6 CTLs/kg via IV, abdominal cavity or tumor injection each time

Primary outcomes

  1. Safety of OC-CTLs in patients using CTCAE version 4.0 standard to evaluate the level of adverse events

    Time frame: 6 months

    Physiological parameter (measuring cytokine response, fever, symptoms)

Secondary outcomes

  1. Functional analyses of OC-CTLs in vitro

    Time frame: 4 weeks

    The specificity of OC-CTLs in vitro will be analysed by enzyme-linked immunospot assay (ELISPOT).

  2. Anti-tumor effects

    Time frame: 1 year

    Objective response, such as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) will be assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria.
