The purpose of this trial is to assess the effectiveness of TroVax® compared to placebo in extending the time to progression in patients with asymptomatic relapsed platinum resistant ovarian, fallopian tube or primary peritoneal cancer.The trial will also look at overall survival times and quality of life.

Primary Outcome Measures:
  • Progression [ Time Frame: At 25 weeks ] [ Designated as safety issue: No ]
    RECIST-defined progression

Secondary Outcome Measures:
  • Immune-related response criteria (irRC) [ Time Frame: 8 weeks post evidence of progression by RECIST 1.1 ] [ Designated as safety issue: No ]
    irRC will be used to identify any delayed response.Patients will remain on treatment until irRc has confirmed progression (in the absence of unacceptable toxicity or the need for urgent chemotherapy).

  • Progression-free survival [ Time Frame: Time from randomisation to clinical intervention or confirmed evidence of progression or death, assessed for up to 2 years ] [ Designated as safety issue: No ]
  • Time to clinical intervention [ Time Frame: Time from randomisation to clinical intervention or death, assessed for up to 2 years ] [ Designated as safety issue: No ]
  • Incidence of clinical intervention [ Time Frame: At 25 weeks from randomisation ] [ Designated as safety issue: No ]
  • CA-125 doubling time [ Time Frame: Assessed at treatment visits for up to 2 years from randomisation. ] [ Designated as safety issue: No ]
    To investigate CA-125 doubling time as an independent prognostic factor.

  • Overall survival [ Time Frame: Time between randomisation and death assessed for up to 4 years ] [ Designated as safety issue: No ]
  • Quality of Life [ Time Frame: For up to 2 years following randomisation or until progression ] [ Designated as safety issue: No ]
    Patient reported outcome and health-related quality of life measured by standardised questionnaires (EORTC QLQ C-30, EORTC QLQ OV-28)

Estimated Study Completion Date: October 2018
Estimated Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TroVax®
TroVax® consists of a highly attenuated VV (Modified Vaccinia Ankara, MVA) containing the human TAA 5T4 under regulatory control of a modified VV promoter, mH5.
Biological: TroVax®
Patients will be randomised to receive either TroVax® 1 x 10↑9 TCID50/mL in 1mL (experimental arm) or matched placebo (control arm) on a 1:1 basis. A single dose will be given by intramuscular injection during the following weeks: 2, 4, 7, 10, 13, 19, 25, 31, 37, 43 and 49. No further treatment will be given beyond week 49.Treatment will be stopped early if confirmed progression or unacceptable toxicity.
Placebo Comparator: Placebo Biological: Placebo
Matched placebo will be administered as above.

Detailed Description:

A significant number of patients with advanced ovarian cancer develop a "CA-125 relapse" without clinical symptoms and with a low volume disease on the CT scan. For this group of patients, no survival benefit has been demonstrated from early chemotherapy treatment and, on average, the time to start of chemotherapy is 5 months. Such patients could benefit from immunotherapy and the time to chemotherapy could potentially be prolonged. Multiple immunotherapy agents, such as anti-CA-125 antibodies and various vaccines, have been tested and, although there is plenty of evidence of immune response, this has not translated to a definitive clinical benefit and is not recommended in clinical practice

5T4 appears to be highly expressed in ovarian cancer and correlates with more advanced stage of disease and poorly differentiated tumours. TroVax®, the vaccine targeting 5T4, has an extensive record of safety and efficacy in humans and vaccination in patients with colorectal, renal, and prostate cancer resulted in immune cellular and humoral responses and signs of clinical benefit.

We propose a trial of TroVax® vaccination in patients with CA-125-relapsed asymptomatic ovarian cancer to assess the clinical efficacy and immunological responses as outlined in this protocol. To allow for capture of any delayed response to immunotherapy, patients who progress on RECIST 1.1 criteria and who do not experience toxicity from treatment will continue on the vaccine/placebo injection until repeat imaging at 8 weeks in order for immune-related response criteria (irRC) to be evaluated in addition to RECIST 1.1 criteria (these patients as a standard of care would not receive any other therapeutic intervention).

Inclusion Criteria:

  • Aged ≥18 years with histologically or cytologically proven advanced [stage Ic - III or stage IV (pleural effusion only)] epithelial ovarian carcinoma, fallopian tube carcinoma or primary peritoneal carcinoma
  • Completed cytoreductive surgery during the phase of first-line therapy including removal of bulky tumour masses and adequate surgical staging including a minimum of bilateral salpingo-oophorectomy, hysterectomy and omentectomy

  • Normal CA-125 following most recent chemotherapy
  • Have developed CA-125 relapse as defined by either elevated CA125 ≥45 or low volume disease on the CT scan (as judged by the investigator)
  • Currently asymptomatic and does not require chemotherapy.
  • Subject is assumed to be clinically immunocompetent and is free of clinically apparent/active autoimmune disease (i.e. no prior confirmed diagnosis or treatment for autoimmune disease including Systemic Lupus Erythematosis, Grave's disease, Hashimoto's thyroiditis, multiple sclerosis, and rheumatoid arthritis). Note: subjects with type I or type II diabetes mellitus can be included, as can subjects with controlled and rarely flaring rheumatoid disease (defined as recent flare within 6 months prior to randomisation)
  • Subject has adequate bone marrow function as defined by Haemoglobin ≥ 110 g/L, white cell count ≥ 3.0 x 109/L, Absolute Lymphocyte Count (ALC) ≥ 1.0 x 109/L, Absolute Neutrophil Count (ANC) ≥1.5 x 109/L , Platelet Count ≥ 100 x 109/L and <400 x 109/L, Monocytes <0.8 x 109/L (for patients who have undergone previous splenectomy monocyte counts can be < 1.2 x 109/L)
  • Adequate end-organ function: plasma creatinine ≤ 2x upper limit of normal, AST and/or ALT ≤ 2x upper limit of normal, Total Bilirubin ≤ 1.5x upper limit normal
  • ECOG performance status 0-1

  • Ability to give written informed consent
  • To be treated no later than 14 days from randomisation

Exclusion Criteria:

  • Carcino-sarcoma/MMMT
  • Cancer related symptoms, or disease recurrence requiring immediate treatment
  • Patients with platinum resistant disease (patients with elevated CA125 within 6 months of completion of surgery and adjuvant chemotherapy who have a normal CT scan can be considered eligible)
  • CT scan showing bulky disease requiring chemotherapy, as judged by the investigator
  • Major surgery/radiation therapy, immunotherapy or chemotherapy completed < 4 weeks prior to randomisation
  • Patients who are deemed as being immunosuppressed, receiving > 4 weeks parenteral or oral steroids, (nasal sprays and inhalers are permitted), or receiving immunosuppressive therapy following transplant
  • Chronic (≥ 6 months) oral corticosteroid use except when prescribed as replacement therapy in the case of adrenal insufficiency. If previously used for ≥6 months then must have discontinued ≥3 months prior to randomisation.
  • "Currently active" second malignancy, other than non-melanoma skin cancer. Subjects are not considered to have a "currently active" malignancy if they have completed therapy ≥3 years previously and have no known evidence of residual or recurrent disease
  • Concomitant use of supplements or complementary medicines/botanicals. The following exceptions are permitted at screening and during the course of the trial:

    • conventional multivitamin supplements
    • selenium
    • lycopene
    • soy supplements
    • Vitamin E
  • Evidence of significant clinical disorder or laboratory finding which in the opinion of the investigator makes it undesirable for the patient to participate in the trial. No participant should have a serious or uncontrolled intercurrent infection (including those positive for HIV, hepatitis B or C)
  • Psychiatric illnesses/social situations that limit compliance with protocol requirements
  • Allergy to egg proteins or history of allergic response to vaccinia vaccines
