Show all 23Show fewer
  • Patients whose ovarian cancer recurs/progresses within 0-6 months following platinum-based chemotherapy have platinum resistant disease; such patients are eligible for this trial
  • Patients with documented disease recurrence/progression within 6-12 months of completing platinum-based therapy, are considered to have 'borderline' platinum sensitivity; these patients are eligible for this trial if agreed by the patient and the treating physician
  • Patients who relapse more than 12 months after completion of platinum-based treatment are considered 'platinum sensitive' and will not be eligible for this trial
  • Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
  • Patients must have a life expectancy of at least 3 months
  • Absolute neutrophil count >= 1,500/ul
  • Platelets >= 100,000/ul; low platelet counts may be corrected with transfusion to achieve eligibility for study
  • The hemoglobin level must be greater than 9 g/dL; low hemoglobin counts may be corrected with transfusion to achieve eligibility for study

  • All subjects must have the ability to understand and the willingness to sign a written informed consent
  • Up to 2 prior chemotherapy regimens for recurrent disease are allowed; adjuvant chemotherapy and maintenance Taxol after completion of six cycles of adjuvant carboplatin
  • Taxol will not be counted as a "prior chemotherapy regimen" for the purpose of this study; treatment with targeted agents or hormones would not be considered as a systemic chemotherapy regimen; previous treatment with gemcitabine is not allowable
  • Eligible patients are those with documented disease recurrence/progression within 0-12 months of completing platinum-based chemotherapy

Who cannot join

  • Patients should not have any uncontrolled illness including ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • No other malignancy is allowed except for the following: adequately treated basal or squamous cell carcinoma, superficial bladder cancer, any carcinoma in situ or any other cancer from which the patient has been disease free for at least 3 years
  • Patients may not be receiving any additional investigational agents or radiation therapy
  • History of severe environmental allergies or allergy to egg proteins
  • Pregnant women are excluded from this study
  • Patients with known brain metastases will be excluded
Show all 12Show fewer
  • Patients who have had radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
  • Patients with a family history or Li-Fraumeni syndrome will not be eligible
  • Concurrent use of corticosteroids (exceptions: nasal corticosteroids, inhaled steroids, adrenal replacement steroids and steroid creams are allowed)
  • Patients with a history of immunodeficiency, including organ grafts and human immunodeficiency virus (HIV), will not be eligible
  • Subjects, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study
  • Patients with any active autoimmune disease or a condition that requires systemic corticosteroids or other immunosuppressive medications will be excluded; exceptions to this are subjects with vitiligo, type I diabetes mellitus and autoimmune thyroiditis only requiring hormone replacement, who will be permitted to enroll

About this study

Official title: A Phase I Study of a p53MVA Vaccine in Combination With Gemcitabine in Ovarian Cancer

This phase I trial studies the side effects and recommended dose of the combination of p53MVA vaccine (modified vaccinia virus ankara vaccine expressing tumor protein p53 [p53]) and gemcitabine hydrochloride in treating patients with ovarian epithelial cancer that has come back. Vaccines made from inserting a laboratory-treated gene into a person's tumor cells may help the body build an effective immune response to kill tumor cells that express p53. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving modified vaccinia virus ankara vaccine expressing p53 together with gemcitabine hydrochloride may work better in treating patients with ovarian epithelial cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine a recommended dose for the combination of a p53MVA vaccine and gemcitabine (gemcitabine hydrochloride) and if it is well-tolerated in patients with platinum resistant, p53 over expressing ovarian cancer.

SECONDARY OBJECTIVES:

  1. To evaluate T cell immunity changes and clinical response.

OUTLINE:

Patients receive modified vaccinia virus ankara vaccine expressing p53 subcutaneously (SC) on day 15 and gemcitabine hydrochloride intravenously (IV) over 30 minutes on days 1 and 8. Treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. Patients then continue to receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recommended dose for the combination of gemcitabine hydrochloride and modified vaccinia virus ankara vaccine expressing p53

    The National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 will be used to grade adverse events. To be evaluable for toxicity, a patient must have received one course of gemcitabine and modified vaccinia virus ankara vaccine expressing p53 or experienced a dose-limiting toxicity.

    Measured: Up to 42 days (2 courses)

Secondary outcomes (2)

  1. Clinical responses, assessed by modified RECIST criteria

    Measured: Up to 12 months

  2. Changes in T cell reactivity to p53

    Peripheral blood samples will be collected pre- and post-immunization for assessment of anti-p53 T cell responses and immunophenotyping. Immunosuppressive cell types (myeloid derived suppressor cells, regulatory T cells) and other selected lymphocyte subsets and markers including programmed cell death protein 1, programmed death-ligand 1 (PDL-1) and PDL-2 will be quantified.

    Measured: Baseline to up to 52 weeks
