Study summary

An open-label Phase 1 trial to evaluate the safety and tolerability of MVA-BN-Brachyury priming and FPV-Brachyury boost vaccines modified to express brachyury and T-cell costimulatory molecules in patients with a metastatic or unresectable locally advanced malignant solid tumor. Subjects will be given the following subcutaneous doses: two prime doses with MVA-BN-Brachyury and monthly boost doses with FPV-Brachyury for 6 months. The study will last approximately 104 weeks before starting long term follow up (FU).

Inclusion criteria

  • Patients must have a or unresectable locally advanced malignant solid tumor, confirmed by the Laboratory of Pathology, NCI. In the case of chordoma, unresectable, locally recurrent, or metastatic tumors are acceptable for enrollment, given that this represents incurable disease. Efforts will be made, as much as possible, to enroll patients with tumor types with known increased expression of brachyury (such as lung, breast, ovarian, prostate, colorectal, pancreatic, hepatocellular, Merkel cell, small cell lung cancer or chordoma; other tumors may be included as data on the level of brachyury in those tumors becomes available). Every attempt will be made to collect , preferably metastatic disease.
  • Patients may have measurable or nonmeasurable but evaluable disease. Patients with surgically resected metastatic disease at high risk of relapse or patients with metastatic disease with a complete response after palliative chemotherapy with at high risk of relapse (such as small cell lung cancer, etc) are also eligible.
  • Prior therapy: Patients must have completed or had disease progression on at least one prior line of disease-appropriate therapy for metastatic disease, or not be candidates for therapy of proven efficacy for their disease.
  • There should be a minimum of 4 weeks from any prior chemotherapy, immunotherapy and/or radiation, with the following exceptions:

    1. Prostate cancer - patients must continue to receive GnRH agonist therapy (unless orchiectomy has been done). Patients on combined androgen blockade therapy may continue those therapies as well (bicalutamide, nilutamide, flutamide, enzalutamide and abiraterone).
    2. Breast cancer - patients may remain on hormonal therapy if indicated (ER/PR+), -directed therapy for HER2+ breast cancer (3+ IHC or FISH+).
    3. EGFR-mutated lung cancer - patient may remain on EGFR inhibiting therapy (tyrosine kinase inhibitors) if they have had stable disease or ongoing response to therapy. Patients with T790M mutations may continue receiving osimertinib while receiving vaccine.
    4. Mestastatic colorectal cancer may continue "maintenance" therapy with capecitabine and/or bevacizumab.
  • There should be a minimum of 6 weeks from any prior antibody therapies, (such as ipilimumab or anti-PD1/PDL1) due to prolonged half-life.
  • Patients must have recovered (grade 1 or baseline) from any toxicity associated with prior therapy.
  • Age ≥ 18 years.
  • performance status ≤ 1 ( ≥ 70%)
  • Patients must have normal organ and marrow function as defined in protocol
  • Women of and men must agree to use adequate (hormonal or barrier method of birth control; abstinence) prior to trial entry and for the duration of trial participation and for a period of 4 months after the last vaccination therapy.)
  • Patients must be able to understand and be willing to sign a written document.

Exclusion criteria

Exclusion Criteria:

  • Concurrent treatment for cancer, with specific exceptions noted in inclusion criteria.
  • Chronic or C infection.
  • Any significant disease that, in the opinion of the investigator, may impair the patient's tolerance of trial treatment.
  • Significant dementia, altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of .
  • Active diseases requiring treatment or a history of autoimmune disease that might be stimulated by vaccine treatment.
  • Concurrent use of systemic , except for physiologic doses of systemic steroid replacement or local (topical, nasal, or inhaled) steroid use. Limited pharmacologic doses of systemic steroids (e.g., in patients with exacerbations of reactive airway disease or to prevent I.V. contrast allergic reaction or anaphylaxis in patients who have known contrast allergies) are allowed.
  • Patients who are receiving any other agents within 28 days before start of trial treatment.
  • Patients with untreated central nervous system or local treatment of within the last 6 months. Patients with stable brain metastasis for 6 months post-intervention are eligible. Subjects with chordoma will be eligible regardless of site of disease if other eligibility criteria are met.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to BN-Brachyury or other agents used in trial. History of allergic reaction to aminoglycoside antibiotics or egg products.
  • Serious or uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with trial requirements.
  • Pregnant women.
  • -positive patients.
Terms in these criteria, in plain language(17)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

HER2

HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.

In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 26, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
