Brief Summary:

Background:

- GI-6207 is an experimental cancer vaccine made with baker's yeast. The yeast has been modified to help the immune system target a protein called CEA. CEA is found on the surface of some kinds of tumor cells, including thyroid cancer cells. Researchers want to see if GI-6207 can encourage the body's immune system to attack and kill tumor cells that contain the CEA protein. They will test to see whether this vaccine is a safe and effective treatment for medullary thyroid cancer that has not responded to earlier treatments.

Objectives:

- To test the safety and effectiveness of the GI-6207 vaccine for advanced medullary thyroid cancer.

Eligibility:

- Individuals at least 18 years of age who have medullary thyroid cancer that has not responded to earlier treatments.

Design:

  • Participants will be screened with a physical exam and medical history. They will provide blood and tumor samples and have an imaging study of the neck and chest. They will also have a skin test to make sure that they are not allergic to the yeast in the vaccine.
  • Participants will be divided into two groups. One group will start to take GI-6207 immediately for 1 year. The second group will have 6 months of monitoring and tests with no vaccine, and then will take GI-6207 for 1 year.
  • GI-6207 will be given every other week for the first seven visits (about 3 months), and then monthly for the remaining year of treatment. It will be given as injections beneath the arm and in the upper thigh. These locations will help the vaccine enter the lymph nodes and reach the immune system more quickly.
  • Participants will be monitored with frequent blood and urine tests and imaging studies.
  • Participants will have regular follow-up visits after their year of study vaccines.

Condition or disease Intervention/treatment Phase
Medullary Thyroid Cancer (MTC) Biological: GI-6207 [Recombinant Saccharomyces cerevisiae-CEA (610D)] Phase 2

Detailed Description:

BACKGROUND:

  • CEA is overexpressed in multiple malignancies, including medullary thyroid cancer where CEA is universally expressed on tumor cells.
  • There is no standard treatment for patients with asymptomatic or minimally symptomatic, metastatic medullary thyroid cancer. The only effective FDA-approved therapy (vandetanib) comes with significant toxicity, so it is not used until patients have symptomatic or rapidly progressing disease.
  • Preclinical studies have shown that GI-6207 can induce a strong immune response to CEA as well as therapeutic anti-tumor responses.
  • A previous Phase I GI-6207 study has demonstrated safety and enhanced immune response in some patients.
  • Preliminary data suggests that tumor growth rates can be calculated in medullary thyroid cancer patients within 3 months
  • Retrospective data from prostate cancer studies suggest that vaccines can alter tumor growth rates within 3-4 months

OBJECTIVES:

Primary:

-To determine the effect of GI-6207 on calcitonin growth rate kinetics after 6 months of therapy in patients with medullary thyroid cancer

ELIGIBILITY:

  • Patients will have evidence of metastatic medullary thyroid cancer including disease that is evaluable on bone or CT scan.
  • Patients with minimal or no disease related-symptoms (minimal symptoms will include those that do not affect activities of daily living or pain that does not require regularly schedule narcotics.)
  • ECOG 0-1
  • No previous chemotherapy
  • No previous vandetanib
  • Should have no autoimmune diseases; no evidence of being immunocompromised; no serious inter-current medical illness; no cardiac disease; no prior splenectomy. (History of previous thyroid autoimmune disease will be allowed as these patients will have had total thyroidectomy.)
  • No brain metastasis, history of seizures, encephalitis, or multiple sclerosis
  • No pericardial-based masses greater than 1 cm or thoracic lesions larger than 2 cm

Design:

  • Randomized, phase 2 study to determine the effect of GI-6207 on calcitonin growth rate after 6 months of GI-6207
  • Patients will be randomized to either initial GI-6207 therapy or 6 months of surveillance followed by GI-6207 therapy.
  • GI-6207 will be administered subcutaneously at 4 sites at dose of 10 yeast units per site, biweekly for 7 visits (day 1, 15, 29, 43, 57, 71, 85), then monthly up to 1 year of treatment. (For patients randomized to surveillance and then GI-6207, they will get a full year of GI-6207 after a 6 month surveillance period.)
  • Once patients have completed one year of therapy with GI-6207, patients without radiographic progression will have the option to receive vaccine every 3 months for an additional 12 months. Patients who remain on vaccine will continue to be scanned every 3 months.
  • Immune monitoring via apheresis will be done prior to enrollment and at 6 months for all appropriate and consenting patients. Patients who are evaluable for immunologic response by the ELISPOT Assay (HLA 02, 03 and 24) will have apheresis at start of GI-6207 therapy and then every 3 months while on GI-6207 treatment when feasible.

Arm Intervention/treatment
Experimental: A
GI-6207 for 1 year
Biological: GI-6207 [Recombinant Saccharomyces cerevisiae-CEA (610D)]
GI-6207 is a heat-killed, recombinant yeast-based vaccine engineered to express the full length human carcinoembryonic antigen (CEA), with a modified gene coding sequence to code for a single amino acid substitution (asparagine to aspartic acid) at the native protein amino acid position 610, which is designed to enhance immunogenicity. A plasmid vector containing the modified human CEA gene is used to transfect the parental yeast strain (S. cerevisiae W303 - a haploid strain with known mutations from wild-type yeast) to produce the final recombinant vaccine product.

Experimental: B
6 months of surveillance followed by GI-6207 for 1 year

Accepts Healthy Volunteers:   No
Criteria
  • INCLUSION CRITERIA:

Participants must meet the following criteria for participation:

  • Diagnosis: Patients must have histologically confirmed medullary thyroid cancer by the Laboratory of Pathology or a pathology report and history consistent with medullary thyroid cancer. It is not uncommon for a secondary, minor pathologic focus of another form of thyroid cancer to be coincidentally found in 15-20% of patients with medullary thyroid cancer. In such cases, eligibility is based on the discretion of the investigator.
  • Patients must have evidence of metastatic medullary thyroid cancer including disease that is evaluable on bone, CT scan or MRI. (Patients who are surgical candidates and potentially rendered disease free with surgical resection are not eligible.)
  • Patients must have elevated calcitonin levels, greater than 8 pg/mL in females and 16 pg/mL in males
  • Patients with minimal or no disease related-symptoms (Minimal symptoms will include those that do not affect activities of daily living or pain that does not require regularly scheduled narcotics.)
  • No brain metastasis, history of seizures, encephalitis, or multiple sclerosis.
  • Age greater than or equal to 18 years
  • ECOG performance status of 0-1 at study entry (Karnofsky greater than or equal to 70)
  • No systemic steroid use within 2 weeks prior to initiation of experimental therapy. Limited doses of systemic steroids to prevent IV contrast, allergic reaction or anaphylaxis (in patients who have known contrast allergies) are allowed.
  • Hematological eligibility parameters

    • Granulocyte count greater than or equal to 1,500/mm^3
    • Platelet count greater than or equal to 100,000/mm^3
    • Hemoglobin greater than or equal to 9 g/dL
  • Biochemical eligibility parameters (within 16 days of starting therapy)

    • Baseline renal function:

      --- Serum creatinine less than or equal to 1.5 x upper limit of normal OR creatinine clearance on a 24-h urine collection of greater than or equal to 60 mL/min.

    • Hepatic function:

      • Bilirubin less than or equal to 1.5 mg/dl, in patients with Gilbert's syndrome, a total bilirubin less than or equal to 3.0 mg/dL
      • AST and ALT< 2.5 times upper limit of normal
  • No other active malignancies within the past 3 years (with the exception of nonmelanoma skin cancers, prostate cancer patients with stable biochemical recurrence/not on systemic therapy or carcinoma in situ of the bladder).
  • Willing to travel to the NIH for follow-up visits
  • Able to understand and sign informed consent.
  • Must agree to use effective birth control (such as a condom) or abstinence during and for a period of 6 months after the last vaccination therapy.

EXCLUSION CRITERIA:

Patients with any of the following will not be eligible for participation in this study:

  • Patients should have no evidence of immune dysfunction as listed below.

    • 1 Human immunodeficiency virus (HIV) positivity due to the potential for decreased immune response to the vaccine.
    • Active autoimmune diseases requiring treatment or a recent history of autoimmune disease requiring therapy, including, but not limited to, inflammatory bowel disease, Crohn's disease, ulcerative colitis, or active diverticulitis. This requirement is due to the potential risks of exacerbating autoimmunity. However, patients with vitiligo may be enrolled. (Patients with history of autoimmune thyroid conditions will be allowed as these patients will be on replacement medications.)
    • Concurrent use of systemic steroids, except for physiologic doses of systemic steroid replacement or local (topical, nasal, eye drops or inhaled) steroid use. Limited doses of systemic steroids (e.g., in patients with exacerbations of reactive airway disease or to prevent IV contrast allergic reaction or anaphylaxis in patients who have known contrast allergies) are allowed.
  • Pregnant or breast-feeding women, due to the unknown effects of GI-6207 on the fetus or infant.
  • Serious inter-current medical illness which would interfere with the ability of the patient to carry out the treatment program.
  • Untreated brain metastases (or local treatment of brain metastases within the last 6 months) due to the poor prognosis of these patients and difficulty ascertaining the cause of neurologic toxicities.
  • Patients with pericardial masses >1 cm or thoracic lesions larger than 2 cm will be excluded.
  • Concurrent chemotherapy.
  • Chronic hepatitis infection, including B and C, because potential immune impairment caused by these disorders may diminish the effectiveness of this immunologic therapy.
  • Participation in another interventional clinical trial at the time of enrollment.
  • Any significant disease that, in the opinion of the investigator, may impair the patient's tolerance of study treatment.
  • Significant dementia, altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of informed consent.
  • Patients with second malignancy within 3 years of enrollment; patients treated surgically with a curative intent, such as non-melanoma skin cancers, localized kidney cancer or carcinoma in situ of the bladder, are not excluded. Patients with MEN2 and a history of pheochromocytoma will also not be excluded. In addition patients with prostate cancer who do not require systemic therapy will not be excluded. (A secondary, minor pathologic focus of another form of thyroid cancer may be coincidentally found in 15-20% of patients with medullary thyroid cancer. In such cases, eligibility is based on the discretion of the investigator.
