Brief Summary:
The purpose of this study is to determine if KM1 is well tolerated with anti-tumor activity in patients diagnosed with recurrent or refractory ovarian cancer, and explore the Recommend Phase 2 Dose (RP2D) of KM1 in the treatment of patients with recurrent or refractory ovarian cancer.

Condition or disease Intervention/treatment Phase
Ovarian Cancer Biological: KM1 Drug: Chemotherapy Phase 1

Detailed Description:
Oncolytic virus therapy is a kind of immunotherapy that can selectively infect and kill tumor cells without damaging normal cells. It has shown good therapeutic effects in the treatment of various types of tumors. KM1 is a genetically modified recombinant vaccinia virus, which has good therapeutic effect on many solid tumors, including ovarian cancer. This study includes Phase Ia and Phase Ib. In the Phase Ia study, subjects will receive three doses intraperitoneal infusion of KM1 followed by chemotherapy. In the Phase Ib study, subjects will receive six doses intraperitoneal infusion of KM1 preceding chemotherapy. Subjects will be followed in the study for 6 months after last dose of chemotherapy.

    Time from study treatment initiation to the first occurrence of disease progression or death (of any cause).

  5. Objective Response Rate (ORR) by RECIST 1.1 [ Time Frame: From date of randomization up to 6 months following last dose of chemotherapy. ]
    The ratio of the sum of Complete Response & Partial Response divided by the number of participants from the start of treatment to confirmation of response.

  6. Disease Control Rate (DCR) RECIST 1.1 [ Time Frame: From date of randomization up to 6 months following last dose of chemotherapy. ]
    The ratio of the sum of Complete Response & Partial Response & Stable Disease divided by the number of participants from the start of treatment to confirmation of response

  7. CA-125 Response [ Time Frame: From date of randomization up to 6 months following last dose of chemotherapy. ]
    Level of CA-125 (UI/ml) at baseline and after treatment measured by Enzyme Linked Immunosorbent Assay (ELISA).

Criteria

Inclusion Criteria:

  • Histologically or cytopathology confirmed epithelial ovarian cancer, fallopian tube cancer or primary peritoneal cancer, except mucinous cancer.
  • Relapsed/refractory subjects who failed to receive systemic treatment (at least one standard platinum containing regimen); Note: If the disease relapses, there should be evidence showing imaging or clinical progress (such as cytological report of new ascites or pleural effusion).
