Brief Summary:
The primary objective of this open-label, Phase I, trial is to evaluate the toxicity profile of intraperitoneal talimogene laherparepvec (TVEC) in patients with peritoneal surface dissemination from gastrointestinal or recurrent, platinum-resistant ovarian tumors. The secondary objectives are to evaluate the pharmacokinetic profile and viral shedding of TVEC by measuring viral load in serum and urine as well as viral load in peritoneal washings.

Condition or disease Intervention/treatment Phase
Stage IV Peritoneal Surface Dissemination From Gastrointestinal or Recurrent, Platinum-resistant Ovarian Cancer That Cannot be Completely Resected Biological: Talimogene Laherparepvec Phase 1

Detailed Description:

This is a non-randomized, open-label Phase I trial in patients with Stage IV peritoneal surface dissemination from gastrointestinal or recurrent, platinum-resistant ovarian tumors enrolled at Duke Cancer Institute. All subjects will complete an extensive medical history, baseline physical examination and clinical assessment to ensure subject eligibility requirements within 4 weeks of starting study drug. All eligible patients must have a peritoneal catheter placed at least 2 weeks prior to the initiation of therapy. All patients will receive an initial loading dose of TVEC 4x106 Plaque Forming Units (PFU) on Cycle 1 Day 1 to enable the formation of protective antibodies as described in the currently approved treatment protocol for the treatment of cutaneous melanoma. Three weeks after the initial loading dose, patients will receive TVEC at the dose level for the cohort for which they are enrolled every 2 weeks for up to 4 doses. The length of the first cycle is 5 weeks and subsequent cycles are 2 weeks in duration.

The first portion of the study, the Dose Escalation cohort, will evaluate the toxicity profile of TVEC in patients with peritoneal surface dissemination from gastrointestinal or recurrent, platinum-resistant ovarian tumors. Using a standard '3+3' dose escalation design, there are up to three dose levels that may be explored. Dose escalation will be dependent on dose-limiting toxicity (DLT) within the cohorts.

Once the MTD has been determined, an additional 6 subjects will be enrolled to the dose expansion cohort. All subjects will receive an initial loading dose of TVEC 4x106 PFU on Cycle 1 Day 1. Three weeks after the initial loading dose, patients will receive TVEC at the MTD every 2 weeks for up to 4 doses. The length of the first cycle is 5 weeks and the subsequent cycles are 2 weeks in duration. There are a total of four cycles.

Arm Intervention/treatment
Experimental: Dose

Drug: Talimogene Laherparepvec

There will be two parts to this phase I study: 1) Dose Escalation Cohort; 2.) Dose Expansion Cohort

In the Dose Escalation Cohort, three subjects will be enrolled at the starting dose of 4x106 PFU, and the dosing will continue in the standard '3+3' dose escalation scheme. If the starting dose is tolerated, enrollment will continue at 4x107 and 4x108 PFU. Once the MTD is determined, six subjects will be enrolled to the Dose Expansion Cohort at the MTD. All subjects will be dosed with talimogene laherparepvec intraperitoneal (IP) once every 2 weeks for up to 4 doses (in addition to the initial seroconversion dose, which all patients will receive).

Biological: Talimogene Laherparepvec
TVEC is an oncolytic, genetically modified virus designed to reproduce in tumor tissue and stimulate your immune system to attack the tumor cells
Other Name: (T-VEC)

Primary Outcome Measures :
  1. Most Tolerable Dose (MTD) for talimogene laherparepvec [ Time Frame: MTD for the study will be determined at the completion of Phase I dose escalation cohort; estimated as 1 year ]
    The MTD across three dose levels will be determined and the safety analyses will be performed on the safety population

  2. Non-dose limiting toxicities for talimogene laherparepvec [ Time Frame: Continuous, approximately every 4 weeks minimum until end of study estimated at 4 years ]
    Adverse events will be recorded

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients must have stage IV peritoneal surface dissemination of gastrointestinal cancer that cannot be completely resected at the time of abdominal exploration, or recurrent, platinum-resistant ovarian cancer with peritoneal metastasese. Radiographically measurable disease is preferable, but for patients with previously documented gastrointestinal or ovarian cancer, for whom tumor markers (CEA or CA-125) have been useful markers of disease progression and/or response to treatment, a rising tumor marker (CEA or CA-125) could be substituted for radiographic imaging.
  2. Subjects must have had at least one prior round of systemic therapy or have refused or be ineligible for standard systemic therapy for their disease type.
  3. Age ≥ 18 years
  4. Eastern Cooperative Oncology Group (ECOG) Performance Score of 0-2
  5. Adequate marrow function as evidenced by:

    1. Absolute neutrophil count (ANC) ≥ 2,000/µL
    2. Platelets ≥ 100,000/µL
    3. Hemoglobin (Hgb) ≥ 9 g/dL
  6. Adequate renal function as evidenced by serum creatinine ≤ 1.5 x upper limit of normal (ULN), OR 24-hour creatinine clearance ≥ 60 mL/min for subject with creatinine levels > 1.5 x ULN.
  7. Adequate hepatic function as evidenced by:

    1. Serum bilirubin ≤ 1.5 x ULN OR direct bilirubin ≤ ULN for a subject with total bilirubin level > 1.5 x ULN
    2. Aspartate aminotransferase (AST) ≤ 3 x ULN
    3. Alanine aminotransferase (ALT) ≤ 3 x ULN
    4. Alkaline phosphatase ≤ 3 x ULN

  9. Patients must be recovered from both acute and late effects of any prior surgery, radiotherapy or other antineoplastic therapy.
  10. Patients of reproductive potential (men and women) must agree to use medically accepted barrier methods of contraception (e.g., male or female condom) at the time of pregnancy test (women of childbearing potential only), during the course of the study and for 90 days after the last dose of study drug, even if oral contraceptives are also used. All subjects of reproductive potential must agree to use both a barrier method and a second method of birth control during the course of study and for 90 days after the last dose of study drug.

Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
