A Phase 2 interventional study of Biospecimen Collection and Blinatumomab in B Acute Lymphoblastic Leukemia, Philadelphia Chromosome Negative, Recurrent B Acute Lymphoblastic Leukemia and Refractory B Acute Lymphoblastic Leukemia, sponsored by National Cancer Institute (NCI). Recruiting at 285 sites in 2 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-28.
Sponsored by National Cancer Institute (NCI) · Phase 2, Interventional, and Treatment
This phase II trial studies how well inotuzumab ozogamicin and blinatumomab with or without ponatinib work in treating patients with CD22-positive B-lineage acute lymphoblastic leukemia that is newly diagnosed, has come back after a period of improvement (recurrent), or does not respond to treatment (refractory). Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug, called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Blinatumomab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving inotuzumab ozogamicin and blinatumomab with or without ponatinib may be effective in treating patients with newly diagnosed, recurrent or refractory CD22 positive B-lineage acute lymphoblastic leukemia.

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.
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.
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.
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.
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.
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 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 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.
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.
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 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.
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.
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.
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.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
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.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.
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.
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.

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.

Event-free survival
Will be defined as time from start of treatment to failure to achieve complete response (CR)/complete response with incomplete count recovery (CRi) after completing Course II of blinatumomab, relapse after CR/CRi, progression on study requiring withdrawal from study therapy, or death from any cause
Time frame: At 1 year
Completion of protocol treatment (cohort 3)
Feasibility defined as completion of the planned therapy as defined in the protocol. Success rate defined as the proportion of patients who either complete entire protocol treatment or go off protocol treatment due to the disease (e.g., refractory disease, progression, and relapse).
Time frame: Up to 10 years
Overall survival (OS)
Will be evaluated using the Kaplan-Meier method. A 95% confidence interval for the 1- and 3-year rates will be constructed using a point-wise confidence interval for the survival function based on a log-minus-log transformation. Will also calculate a 95% confidence interval by using a point-wise confidence interval for the survival function based on a log-minus-log transformation.
Time frame: Time from start of study therapy to death from any cause censored at the last known alive date, assessed up to 10 years
Relapse-free survival (RFS)
Will be evaluated using the Kaplan-Meier method. A 95% confidence interval for the 1- and 3-year rates will be constructed using a point-wise confidence interval for the survival function based on a log-minus-log transformation. Will also calculate a 95% confidence interval by using a point-wise confidence interval for the survival function based on a log-minus-log transformation.
Time frame: Time from first CR/CRi to progressive disease (relapse, treatment discontinuation due to health deterioration) or death, assessed up to 10 years
Event-free survival (EFS)
Will be evaluated using the Kaplan-Meier method. A 95% confidence interval for the 1- and 3-year rates will be constructed using a point-wise confidence interval for the survival function based on a log-minus-log transformation. Will also calculate a 95% confidence interval by using a point-wise confidence interval for the survival function based on a log-minus-log transformation.
Time frame: Time from start of treatment to failure to achieve CR/CRi after completing Course II of blinatumomab, relapse after CR/CRi, progression on study requiring withdrawal from study therapy, or death from any cause, assessed up to 10 years
Complete and overall response rate
Point and interval estimates of the rates will be shown using a 95% binomial confidence interval.
Time frame: Up to 10 years
Minimal residual disease negativity
Time frame: Up to 10 years
Complete molecular response
Defined as negative BCR-ABL1 quantitative real time polymerase chain reaction on bone marrow aspirate in patients in CR/complete response with partial hematologic recovery/CRi.
Time frame: Up to 10 years
Allogeneic hematopoietic cell transplantation rate (Cohort 2)
Point and interval estimates of the rate will be shown using a 95% binomial confidence interval.
Time frame: Up to 10 years
Rate of cytokine release syndrome (Cohort 1)
Point and interval estimates of the rate will be shown using a 95% binomial confidence interval.
Time frame: Up to 10 years
Sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) of the liver
The rate of, timing of, and risk factors for SOS/VOD of the liver after limited inotuzumab ozogamicin exposure. Point and interval estimates of the rate will be shown using a 95% binomial confidence interval. A summary of the timing and risk factors for SOS/VOD of the liver will be provided.
Time frame: Up to 10 years
OS
Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation versus (vs.) patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. The median, 1-year, and 2-year OS will be compared between the above two groups. The distribution of OS for each group will be estimated using the Kaplan-Meier method.
Time frame: Up to 2 years
RFS
Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation vs. patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. The median, 1-year, and 2-year RFS will be compared between the above two groups. The distribution of RFS for each treatment arm will be estimated using the Kaplan-Meier method.
Time frame: Up to 2 years
Cumulative incidence of relapse (CIR)
Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation vs. patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. Competing risk analysis will be done to compare the relapse rates between the above two groups. In this analysis, death will be considered a competing event. Relapse rates at the 1-year and 2-year time points will be estimated. Other time points of interest may be estimated as well.
Time frame: Up to 2 years
Non-relapse mortality
Will compare between patients achieving CR/CRi and receiving consolidation with allogeneic hematopoietic cell transplantation vs. patients achieving CR/CRi and receiving consolidation without allogeneic hematopoietic cell transplantation. Competing risk analysis will be done to compare the mortality rates between the above two groups. In this analysis, relapse will be considered a competing event. Mortality rates at the 1-year and 2-year time points will be estimated. Other time points may be estimated as well.
Time frame: Up to 2 years
