This is a Phase I/II, open-label dose-escalation study designed to evaluate the maximum tolerated dose (MTD) and dose-limiting side effects of ibrutinib (560 or 840 or 420 mg daily oral dose), given in combination with trastuzumab administered through the vein, in patients with HER2-amplified Metastatic Breast Cancer that has gotten worse after prior therapy with ado-trastuzumab emtansine (T-DM1).
Ado-trastuzumab emtansine (T-DM1) is approved by the FDA for patients with HER2-positive metastatic breast cancer (MBC) previously treated with a taxane and trastuzumab, and is currently listed as the preferred second-line therapy in the NCCN guidelines (NCCN 2014). While the benefit of continued HER2 inhibition has been conclusively established for disease that has progressed on a trastuzumab-containing regimen, there are currently no data regarding the efficacy of HER2- targeted therapies following progression on T-DM1.
With the population of T-DM1-treated patients steadily growing, clinical trials are needed to investigate novel therapies in this setting,to meet the medical need for effective, evidence-based therapies for these patients.
The oral small-molecule Bruton's Tyrosine Kinase (BTK) inhibitor ibrutinib has also demonstrated the ability to inhibit erythroblastosis virus oncogene B (ErbB)/HER receptor family kinases in preclinical studies at clinically relevant concentrations, with an equivalent or greater potency than other HER2-directed tyrosine kinase inhibitors (TKIs) with demonstrated activity in HER2-positive MBC, including lapatinib, neratinib, and afatinib. Of note, in preclinical HER2-positive cell model systems the growth inhibitory ability of ibrutinib was substantially greater in HER2-amplified breast cancer cells versus those that simply overexpressed the HER2 protein.
Ibrutinib is currently approved for use in patients with Chronic lymphocytic leukemia (CLL) or Mantle cell lymphoma (MCL), and has an established safety record from clinical trials in these patient populations. Thus there is a reasonable rationale to investigate ibrutinib in patients with HER2- amplified MBC, in the setting of T-DM1-pretreated disease. Previous studies have demonstrated that combined targeting of HER2 with multiple HER2-directed agents is more effective that single agent therapy and therefore this study will explore the safety and efficacy of ibrutinib in combination with trastuzumab.
This is a Phase I/II, open-label, unblinded, nonrandomized, standard 3+3 dose-escalation study designed to evaluate the maximum tolerated dose (MTD) and dose-limiting toxicities (DLT) of ibrutinib (560 or 840 or 420 mg QD) given orally in combination with trastuzumab (8 mg/kg loading dose followed by 6 mg/kg q3w) administered intravenously (IV) in patients with HER2-amplified MBC that has progressed on prior therapy with ado-trastuzumab emtansine.
Once the recommended phase II dose of ibrutinib plus trastuzumab has been determined (no more than 1 of 6 patients with dose-limiting toxicity) in the required 6 to 18 patients over the 3 possible dose levels, additional patients will be enrolled on the phase II part of the study at the recommended phase II dose of ibrutinib plus trastuzumab, for a maximum of 51 patients total.

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.
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.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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.
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.
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.
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).
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.
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.
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.
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.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
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.
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.
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.
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.
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.
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).
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.
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.
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.
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.
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.
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.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
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 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.
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.

The New York Heart Association’s four classes of how much heart failure limits physical activity.
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.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.
