Study summary

In epithelial cancer, MUC-1(mucin-1) overexpression is thought to disrupt E-cadherin function, leading to anchorage-independent tumor cell growth and metastases. Elevated levels of MUC-1 expression have been found in patients with epithelial cancers of breast, ovarian, colon and lung. Furthermore, overexpression of MUC-1 is independently correlated with adverse clinical phenotypes, metastases and resistance to chemotherapy. In animal models, suppressing the expression of MUC-1 reduces the rates of growth and metastasis and increases the sensitivity of the cancer to chemotherapy-induced cell death.

In this study, an adenoviral Ad-sig-hMUC-1/ecdCD40L vector encoding a fusion protein in which the hMUC-1 epithelial antigen is attached to the CD40L (CD40 ligand). The preclinical results have also shown that two subcutaneous Ad-sig-hMUC-1/ecdCD40L vector injections can induce immunity through activation of dendritic cells and promotion of antigen specific B cells or antigen specific CD8 effector T cells which suppresses the growth of hMUC-1 tumor cells in 100% of the vaccinated mice without Interleukin (IL) 2 stimulation being required, this suggests that the Ad-sig-hMUC-1/ecdCD40L vector prime-hMUC-1/ecdCD40L protein boost has the potential to be an effective vaccine in epithelial tumors. Therefore, the safety and tolerability of the Ad-sig-hMUC-1/ecdCD40L vector vaccine will be tested in this phase I non-randomized open label dose escalation trial for men or women with metastatic or recurrent epithelial cancers of the lung, breast, ovary, prostate and colon.

Terms in these criteria, in plain language(24)

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.

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.

Metastases

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

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

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.

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.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

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.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

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.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

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.

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.

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Leptomeningeal disease

Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.

Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

  • Experimental
    Ad-sig-hMUC-1/ecdCD40L vector vaccine

    Experimental: Ad-sig-hMUC-1/ecdCD40L vector vaccine This trial has six cohorts with 3 subjects planned for each cohort. Subjects in the 1st cohort will receive 1 dose of vaccine injection at the lowest planned dose of the vector, 1 x 10\^9 VP. If none of the patients in the 1st cohort experience Dose limiting toxicity (DLT), a 2nd cohort will receive 1 dose of 1x10\^10 VP. If none of the patients in the 2nd cohort experience DLT, the dose escalation will continue with the 3rd cohort receiving 1 doses of 5 x 10\^10 VP per injection. The patients in the 4th cohort will receive 1 injection of 1x10\^11 if no DLT occurs in the preceding cohort. Additional patients will be added to cohort 5 or 6 if DLTs are encountered in the first 3 patients tested in each of these cohorts.

What researchers measure

Primary outcomes

  1. Assessment of a safe, tolerable, and immunologically active dose level of the Ad-sig-hMUC-1/ecdCD40L vector vaccine

    Traditional 3+3 dose escalation scheme is employed for this trial. This trial has 6 cohorts with 3 subjects for each cohort. Subjects in the 1st cohort will receive the lowest planned dose of the vector, 1 x 10\^9 VP. If no patient in the 1st cohort experiences Dose limiting toxicity (DLT), a 2nd cohort will receive 1 dose of 1x10\^10 VP. Similarly, if no DLT occurs in the preceding cohorts, the dose escalation will continue with the 3rd cohort receiving 1 dose of 5 x 10\^10 VP and the 4th cohort receiving 1 dose of 1x10\^11 VP. Following completion of the 4th cohort, the toxicity of adding 1 or 2 booster injections at 7 and 21 days following the 1st vector injection will be tested in the 5th and 6th cohorts. The dose of each of the 2 or 3 vector injections administered in the 5th and 6th cohorts will be the top dose tolerated in the first 4th cohorts. If DLT is encountered in the first 3 patients in cohorts 5 or 6, then additional patients will be added to each of these cohorts.

    Time frame: Subjects will be followed up to 12 weeks after vaccine injection.
