Specialized Immune Cells (nCTLs) and a Vaccine (Alpha-type-1 Polarized Dendritic Cells) in Treating Patients With Stage II-IV Ovarian, Fallopian Tube, or Primary Peritoneal Cancer

November 20, 2023 updated by: Roswell Park Cancer Institute

A Phase I/IIa Safety and Immunologic Efficacy Trial of Intraperitoneal Induction of CTLs Combined With Alpha-Dendritic Cell Vaccine for Primary Ovarian Cancer

This phase I/IIa trial studies the side effects and best dose of a type of specialized immune cell (natural killer cell-like cytotoxic T-lymphocytes (CTLs) (nCTLs) and how well they work when given with a vaccine (alpha-type-1 polarized dendritic cells) in treating patients with stage II-IV ovarian, fallopian tube, or primary peritoneal cancer. nCTLs are immune cells that are isolated from each patient?s blood and "taught" in the laboratory how to recognize and eliminate tumor cells. These "educated" immune cells are then given back to the patient. An alpha-type-1 polarized dendritic cell vaccine is another population of "educated" immune cells that work to support the infused nCTLs. Giving nCTLS with a dendritic cell vaccine may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

Detailed Description

PRIMARY OBJECTIVES I. To evaluate the safety, tolerability, and feasibility of intraperitoneal (i.p.) administration of autologous tumor loaded DC vaccines (alpha-type-1 polarized dendritic cell [alphaDC1]) combined with intradermally administered aDC1 .(Safety [Phase I aspect]) II. To measure the intraperitoneal induction and persistence of aDCI induced sensitized cytotoxic T Cells (CTLs), which express natural killer (NK) cell-like features (nCTLs) and total CTLs following intraperitoneal administration of aDC1. (Local Immunologic Efficacy [Phase II aspect])

SECONDARY OBJECTIVES I. To study the T cell populations generated that correlates with higher anti-tumor responses.

EXPLORATORY OBJECTIVES I. To evaluate the progression-free survival and overall survival of patients treated with this regimen.

OUTLINE: This is a phase I, dose-escalation study of nCTLs, followed by a phase IIa study.

Patients receive the alpha-type-1 polarized dendritic cell vaccine intradermally (ID) 2 weeks before day 0, on day 0, and on day 28. Patients also receive nCTLs intraperitoneally (IP) over 15-30 minutes on day 0. In the absence of unacceptable side effects, patients may receive the alpha-type-1 polarized dendritic cell vaccine every 1-3 months at the discretion of the physician.

After completion of study treatment, patients are followed up at 14 days, then at 6 and 12 months.

Exclusion Criteria:

  • Metastatic disease to the central nervous system and any site above diaphragm.
  • Other serious illnesses (e.g., serious infections requiring antibiotics [with the exception of uncomplicated UTI], bleeding disorders).
  • Chemotherapy, radiation therapy, or immunotherapy within 4 weeks prior to first dosing of study agent. Concomitant hormonal therapies are allowed.
  • Patients who have an active autoimmune disease (e.g., rheumatoid arthritis, systemic lupus erythematosus [SLE], ulcerative colitis, Crohn's Disease, multiple sclerosis [MS], ankylosing spondylitis) requiring chronic use of steroids or other immunosuppressives.
  • Patients being chronically treated with immunosuppressive drugs such as cyclosporin, adrenocorticotropic hormone (ACTH), or systemic chronic corticosteroids. NOTE: Recent or current use of inhaled steroids is not exclusionary.

    • NOTE: Recent or current use of inhaled steroids is not exclusionary. If subjects are prescribed a brief course of oral steroids, the use should be limited to less than 7 days. Use of steroids before apheresis and immune assessment blood draws will affect white blood cell function (wash out period of 1 week).
  • Patients with a known immunodeficiency disease including cellular immunodeficiencies, hypogammaglobulinemia or dysgammaglobulinemia; patients who have acquired, hereditary, or congenital immunodeficiencies. Specific testing is not required, however may be done as clinically indicated.

  • Patients with a history of other invasive malignancies, with the exception of nonmelanoma skin cancer, are excluded if there is any evidence of other malignancy being present within the last three years. Patients are also excluded if their previous cancer treatment contraindicates this protocol therapy.
  • Evidence of current drug or alcohol abuse or psychiatric impairment, which in the investigator's opinion will prevent completion of the protocol therapy or follow-up. Specific testing is not required, however may be done as clinically indicated.
  • Any condition that in the opinion of principal investigator (PI) would preclude patient from successfully completing the protocol therapy or follow-up.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of adverse events as assessed by Cancer Therapy Evaluation Program (CTEP) version 4 of the Common Terminology Criteria for Adverse Events (CTCAE)
Time Frame: Up to 12 months
Up to 12 months
Dose-limiting toxicities (DLT) assessed by CTCAE version 5
Time Frame: Up to 14 days after intraperitoneal (IP) infusion of nCTLs
Will be used in the estimation of the maximum tolerated dose (MTD) and the accompanying of the dose escalation decisions. However, no formal analyses of DLTs are planned.
Up to 14 days after intraperitoneal (IP) infusion of nCTLs
Change in immune response
Time Frame: From baseline (day 0) to day 2 (48 hours after adoptive cell therapy [ACT]) administration
Change in immune response will be measured by the increase in the number of CD3+CD8+NKG2D (high) natural killer cell-like cytotoxic T-lymphocyte (CTLs) (nCTLs) and the increase in total CD3+CD8+ CTLs recovered in the peritoneal washes with evaluation on day 0 versus day 2. The analysis will consist of an analysis-of-covariance (ANCOVA) for the outcome of post-pre ACT treatment cell count with a factor for dose and sampling time 48 hrs +/- 24 hrs.
From baseline (day 0) to day 2 (48 hours after adoptive cell therapy [ACT]) administration
Persistence of nCTLs after their adoptive transfer
Time Frame: Up to 4 weeks
At day 0 will obtain peritoneal material (outflow and washes) directly before i.p. infusion of nCTLs, as well as day 2 (48 hours +/- 24 hours), day 7 (+/- 2 days), 2 weeks (14 days +/- 2 days) and 4 weeks (28 days +/- 3 days) later.
Up to 4 weeks
