Study summary

Background:

Olfactory neuroblastoma (ONB) is a rare cancer of the nasal cavity. At diagnosis, it is usually locally advanced. It tends to spread to the neck. Sometimes it spreads to the lungs and bones. Researchers want to find a better way to treat it.

Objective:

To learn if giving immunotherapy drug bintrafusp alfa can help ONB shrink or disappear.

Eligibility:

People aged 18 years and older diagnosed with recurrent or metastatic ONB that has not responded to standard treatment.

Design:

Participants will be screened with a medical history, blood and urine tests, and physical exam. Their ability to perform their normal activities will be assessed. They will have an electrocardiogram to evaluate their heart. They will have imaging scans and/or a nuclear bone scan, as needed. For some scans, they may receive a contrast dye.

Some screening tests will be repeated during the study.

Participants will receive bintrafusp alfa once every 2 weeks for 26 doses. They will get it intravenously over 60 minutes. They may get other medicines to prevent side effects. They will complete health questionnaires. Visits will last 4-6 hours.

Participants may have optional tumor biopsies.

Participants will have an end of treatment visit within 7 days after they stop taking the study drug. About 28 days after treatment ends, they will have a safety visit. They will have follow-up visits every 3 months for the first year, then every 6 months for years 2-5, and then once a year after that for the rest of their life. If their disease progresses, they may be eligible for re-treatment with the study drug

Read the detailed description

Background:

Olfactory neuroblastoma (ONB, also known as esthesioneuroblastoma), is a rare malignant neoplasm of the nasal cavity. At diagnosis, ONB is often locally advanced. It tends to invade locally and has high rates of regional spread to the neck, and distally to the lungs and bones. The 10-year survival rate for ONB is reported at 46%.

Standard of care treatment is surgical resection followed by adjuvant radiation. In advanced unresectable or metastatic cases, systemic chemotherapy is used off label, with agent selection based on published case series. Genomic profiling of ONB has not yet informed the utilization of an appropriate molecularly targeted treatment.

High programmed death-ligand 1 (PD-L1) expression by immunohistochemistry was shown in ONB tumor samples, providing a rationale for immune checkpoint blockade in ONB. In addition, high expression of transforming growth factor beta (TGF-beta) ligands has been identified in ONB, implying that additional benefit may be achieved by combination of checkpoint blockade with TGF-beta inhibition.

Bintrafusp alfa is a novel bifunctional fusion protein composed of a blocking monoclonal antibody against PD-L1 fused with the soluble extracellular domain of the human TGF-beta receptor II (TGF-betaRII), acting as a decoy target for TGF-beta. The safety profile of bintrafusp alfa in clinical trials to date has been shown to be manageable.

Objective:

To assess the objective response rate (ORR) to bintrafusp alfa in participants with recurrent/metastatic ONB, immune checkpoint-naive (CN)

Eligibility:

Participants must have histologically confirmed recurrent or metastatic ONB, not amenable to potentially curative local therapies.

Participants should have received at least one line of systemic therapy including a platinum agent, with evidence of disease progression clinically or radiographically.

Presence of >= 1 lesion measurable by Response Evaluation Criteria in Solid Tumors, (RECIST) 1.1 criteria

Age >= 18 years, men and women

Adequate organ function, and without serious comorbidity (e.g., autoimmune disease), that would preclude concurrent systemic treatment.

Design:

Single-institution, single-arm Phase II trial to determine overall response rate (ORR) in participants with recurrent/metastatic ONB treated with bintrafusp alfa.

Participants will be treated with bintrafusp alfa 1200 mg every 2 weeks for 26 doses.

The trial will initially enroll 12 checkpoint-naive (CN) participants; if responses are observed in one or more participants, the second stage will enroll another 9 CN participants to define the response rate to bintrafusp alfa, for a total of 21 CN participants.

An additional cohort of checkpoint-resistant (CR) participants will be enrolled and evaluated separately. Initially 5 CR participants will be enrolled; if responses are observed in one or more participants, the second stage will enroll another 3 participants, for a total of up to 8 CR participants. Accrual for CR participants will end when the preset number of CN participants has been accrued.

Terms in these criteria, in plain language(32)

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.

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.

Metastases

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

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

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.

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.

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.

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.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

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.

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.

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.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

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.

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.

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.

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.

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

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.

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

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.

What researchers measure

Primary outcomes

  1. Percentage of Participants With an Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

    ORR is defined as the percentage of evaluable participants who experience a response evaluated by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 reported along with a 95% two-sided confidence interval. Complete Response (CR) is disappearance of all target lesions. Partial Response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Progressive Disease (PD) is at least a 20% increase in the sum of the diameters of target lesions. Stable Disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.

    Time frame: Cycle 1 (28 days)

Secondary outcomes

  1. Number of Participants Who Experience a Toxicity Related to Bintrafusp Alfa (M7824), by Grades (1, 2, 3, 4 and/or 5) and Type of Toxicity

    The number of participants who experience toxicity, by grade and type of toxicity related to Bintrafusp alfa (M7824) was assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe. Grade 4 is life-threatening. Grade 5 is death related to adverse event. A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

    Time frame: up to 2 years

  2. Overall Survival (OS)

    OS is defined as the time from the date of first treatment to the date of death (any cause) using the Kaplan-Meier method.

    Time frame: Through study completion, an average of 2 years

  3. Duration of Response (DOR)

    DOR is defined as the time measurement for complete response (CR) or partial response (PR) (whichever is first recorded) until the first documented date of progressive disease (PD) or death. ORR was evaluated by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 using the Kaplan-Meier method and reported along with a 95% two-sided confidence interval. Complete Response (CR) is disappearance of all target lesions. Partial Response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Progressive Disease (PD) is at least a 20% increase in the sum of the diameters of target lesions.

    Time frame: Through treatment completion, an average of 1 year

  4. Progression Free Survival (PFS)

    PFS is defined as the time from the date of first treatment to the date of disease progression or death (any cause) whichever occurs first, using the Kaplan-Meier method and reported along with a 95% confidence interval. Disease progression was evaluated by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 and is at least a 20% increase in the sum of the diameters of target lesions.

  1. Number of Participants With Serious and/or Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0)

    Here is the number of participants with serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

    Time frame: Adverse Events were monitored/assessed from first drug administration through 30 days after the last dose of study drug is administered, an average of 6 months.

Outcome measures

PrimaryPercentage of Participants With an Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

ORR is defined as the percentage of evaluable participants who experience a response evaluated by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 reported along with a 95% two-sided confidence interval. Complete Response (CR) is disappearance of all target lesions. Partial Response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Progressive Disease (PD) is at least a 20% increase in the sum of the diameters of target lesions. Stable Disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.

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 8, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
