Study summary

A first-in-human evaluation of SYN004, a monoclonal antibody that binds to the EGF receptor on cancer cells. Cetuximab, a marketed antibody, has been shown to be effective by inhibiting the growth of cancer cells thereby prolonging the life of patients who have received it. SYN004 is a closely related monoclonal antibody also binds to the EGF receptor in the same way. SYN004 might also inhibit cancer cells and prolong life but has been engineered to avoid some of the hypersensitivity reactions known to provoked by cetuximab.

Study Design:

In this open-label, dose escalation study, subjects will receive a single IV loading dose of SYN004 on Day 1 of the first treatment week, followed by up to 7 fixed weekly doses of SYN004. Subjects will be assigned to loading and fixed doses by dose group.

Each dose group will comprise 3 subjects and may be expanded to 6 subjects. Subjects will enter dose groups in the order in which they are enrolled. There will be no intra-subject dose adjustments.

Only 1 subject in a cohort may receive the loading dose of SYN004 on any given day; at least 1 day must elapse before the next subject in the cohort receives the loading dose.

Study SYN004-001 Dose Matrix. Three initial subjects will be enrolled followed by an additional three if specified by protocol. Dose levels are specified below.

Group 1: Loading dose: 100 mg/m2; Weekly Dose: 62.5 mg/m2. Group 2: Loading dose: 200 mg/m2; Weekly Dose: 125 mg/m2. Group 3: Loading dose: 400 mg/m2; Weekly Dose: 250 mg/m2.

After each dose of IV SYN004, subjects will be observed in the clinic for 12 hours. After the loading dose, subjects will undergo safety evaluations on Days 2, 3 and 5. Safety evaluation will also be performed on Day 1 (pre-treatment) and Day 3 of each fixed dose treatment week.

Dose-limiting toxicities (DLTs) are defined as any Grade ≥3 AE assessed by the investigator or Medical Monitor, with agreement of the Safety Review Board (SRB), as related to SYN004. Subjects with DLTs will be withdrawn from treatment. If 2 or more subjects in a dose group experience DLTs, or one subject in a dose group experiences a Grade ≥3 infusion reaction, all subjects in that dose group will be withdrawn from treatment.

Subjects in the dose groups are considered evaluable for dose escalation decisions if they receive at least 4 doses of SYN004, or discontinue SYN004 because of a DLT.

Subjects who withdraw or are terminated per protocol before receiving 4 doses of SYN004 will be replaced.

For subjects who receive at least 4 doses of SYN004, End of Study CT scans for RECIST (version 1.1) evaluation will be performed six (6) days following the final SYN004 treatment.

There will be a 28-day safety monitoring period following the final dose of SYN004 for all subjects in the study. All subjects will attend an End-of-Study Visit 28 days after the final dose of SYN004.

Subjects who complete Cycles 1 and 2, who have evidence of improvement per RECIST 1.1 (i.e., findings of complete or partial response per RECIST 1.1) and meet the other eligibility criteria will be offered up to 3 additional treatment cycles (i.e., up to 12 additional weekly doses) of SYN004 in the SYN004-001 Extension Study. During the Extension Study, subjects will receive the same fixed dose of SYN004 they received in Cycles 1 and 2.

Dose escalation will proceed according to a standard 3+3 study design.

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.

Metastases

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

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

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.

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.

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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

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.
