Study summary

This phase Ib/II trial studies the side effects and best dose of anti-OX40 antibody PF-04518600 (OX40) and how well it works alone or in combination with venetoclax, avelumab, glasdegib, gemtuzumab ozogamicin, and azacitidine in treating patients with acute myeloid leukemia that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as OX40, avelumab, and gemtuzumab ozogamicin, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Glasdegib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as venetoclax and azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving OX40, venetoclax, avelumab, glasdegib, gemtuzumab ozogamicin, and azacitidine may work better in treating patients with acute myeloid leukemia.

Read the detailed description

PRIMARY OBJECTIVES:

I. To evaluate the safety of multiple combination regimens of IO-agents (PF04518600 [Ox40 agonist monoclonal antibody (mAb)], avelumab [PD-L1 antagonist mAb], hypomethylator therapy (azacitidine), anti CD33 mAb (gemtuzumab ozogamycin, GO), Bcl-2 inhibitor (venetoclax) and smoothened pathway inhibitor (glasdegib) in patients with relapsed/refractory (RR) acute myeloid leukemia (AML).

II. To evaluate the composite complete response (CRc) defined as complete response (CR) + complete response with incomplete recovery of platelets (CRp) + complete response with incomplete recovery of counts (CRi) within 3 months of therapy initiation in patients with RR AML of: Arm A. PF-04518600 alone, Arm B. azacitidine + venetoclax + GO, Arm C. azacitidine + aveluma + GO, Arm D. azacitidine + venetoclax + avelumab, Arm E. Azacitidine + avelumab + PF-04518600, Arm F. GO + glasdegib.

SECONDARY OBJECTIVES:

I. To assess the morphologic leukemia free survival (MLFS), partial response (PR), hematologic improvement (HI) rate of patients with RR AML treated on arms A-F.

II. To assess relapse-free survival (RFS), time to next therapy (TNT), 4-week and 8-week mortality, and overall survival (OS) of patients with RR AML treated on arms A-F.

III. To assess minimal residual disease (MRD) by multiparametric flow-cytometry at response (+/- 1 month) and assess correlation of MRD to OS in arms A-F.

EXPLORATORY OBJECTIVES:

I. To study immunological and molecular features at baseline and at predefined time-points on-therapy with each combination in the peripheral blood and bone marrow to include quantification of immune ligand expression by the AML/myelodysplastic syndrome (MDS) blasts and AML/MDS stromal components (myeloid-derived suppressor cell [MDSC]s, monocytes and mesenchymal stem cell [MSC]s) including galectin 9, 4-1BBL, ICOSL, PD-L1, PD-L2, OX-40L, CD137L, others.

II. To study immunological and molecular features at baseline and at predefined time-points on-therapy with each combination in the peripheral blood and bone marrow to include determination of the quantitative expression of positive and negative co-stimulatory molecules including 4-1BB, CTLA-4, ICOS, PD-1, OX40, LAG-3, TIM-3, HLA-DR, Ki67, others on T-lymphocyte subsets.

III. To study immunological and molecular features at baseline and at predefined time-points on-therapy with each combination in the peripheral blood and bone marrow to include identification of the immunophenotype of tumor-infiltrating T-lymphocytes (TILs) pre- and post-therapy including CD8+, CD4+ effector, CD4+ regulatory TILs and central memory, effector memory, and naive T-cell subsets among the CD4 and CD8 populations.

IV. To develop a micro-array based gene expression profile (GEP) predictor of response to the immune combinations using either baseline ribonucleic acid (RNA) sequencing and/or nanostring.

V. To perform a validated next generation sequencing (NGS)-based analysis for the detection of somatic mutations in the coding sequences of 28 genes commonly mutated in AML at baseline and on treatment to identify baseline predictors and clonal evolution on treatment and/or whole exome sequencing (WES) in selected cases.

VI. To identify clonal T-cells by performing T-cell repertoire analysis at baseline and longitudinally on therapy on the peripheral blood and/o bone marrow samples.

VII. To assess levels of cytokines at baseline and longitudinally on therapy in peripheral blood and/or bone marrow.

Inclusion criteria

  • ARMS A-G: RR AML: Patients with AML who are or relapsed (any salvage) with no available therapies or not candidates for available therapies. For patients with prior MDS or chronic myelomonocytic leukemia (CMML) or myeloproliferative neoplasm (MPN) who transformed to AML, therapy received for MDS, CMML, or MPN is NOT considered as prior therapy for AML with the exception of MDS or CMML treated with hypomethylating agents (HMAs). Patients with MDS or CMML treated with HMA therapies who progress to AML, and have no available therapies or are not candidates for available therapies, will be eligible at the time of progression to AML.
  • Prior therapy with hydroxyurea, chemotherapy, biological or targeted therapy (e.g. FLT3 inhibitors, other kinase inhibitors), or hematopoietic growth factors is permitted.
  • (ECOG) performance status =\< 2.
  • Total =\< 2.0 times (x ULN).
  • or alanine aminotransferase =\< 2.5 x ULN (aspartate aminotransferase or alanine aminotransferase =\< 5.0 x ULN if deemed related to leukemia by the treating physician).
  • Adequate renal function defined by an estimated >= 40 mL/min according to the Cockcroft-Gault formula (or local institutional standard method).
  • Patients must provide written .
  • In the absence of rapidly progressive disease, the interval from prior treatment to the time of initiation of protocol therapy will be at least 14 days for prior anti-leukemic therapy, with the exception of hydroxyurea as noted below, OR at least 5 half-lives for cytotoxic/noncytotoxic agents, whichever is shorter. The half-life for the therapy in question will be based on published pharmacokinetic literature (abstracts, manuscripts, investigator brochure's, or drug-administration manuals) and will be documented in the protocol eligibility document. The toxicity from prior therapy should have resolved to grade =\< 1, however alopecia and sensory neuropathy grade =\< 2 not constituting a safety risk based on investigators judgement is acceptable. Since the effect of most IO-agents, HMA-therapies, SMO-inhibitors, venetoclax may be delayed, use of hydroxyurea for patients with rapidly proliferative disease is allowed before the start of study therapy and will not require a .
  • Concurrent therapy for central nervous system (CNS) prophylaxis or continuation of therapy for controlled CNS disease is permitted. Patients with a known history of CNS disease or leukemic must have been treated locally, have at least 3 consecutive lumbar punctures (LPs) with no evidence of CNS leukemia, and must be clinically stable for at least 4 weeks prior to enrollment and have no ongoing neurological symptoms that in the opinion of the treating physician are related to the CNS disease (sequelae that are a consequence of the treatment of the CNS disease are acceptable).
  • Females must be surgically or biologically sterile or (amenorrheic for at least 12 months) or if of , must have a negative serum or urine pregnancy test within 72 hours before the start of the treatment.
  • Women of childbearing potential must agree to use an adequate method of during the study and until 3 months after the last treatment. Males must be surgically or biologically sterile or agree to use an adequate method of contraception during the study until 3 months after the last treatment. Adequate methods of contraception include:

    • Total abstinence when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
    • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
    • Male sterilization (at least 6 months prior to screening). For female patients on the study, the vasectomized male partner should be the sole partner for that patient.
    • Combination of any of the two following:

      • Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate \< 1%), for example hormone vaginal ring or transdermal hormone contraception.
      • Placement of an intrauterine device (IUD) or intrauterine system (IUS).
      • Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository in case of use of oral contraception, women should have been stable on the same pill before taking study treatment.
    • Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction. Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.

Terms in these criteria, in plain language(26)

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.

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.

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.

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.

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.

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.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

Brain metastases

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

QT and QTc

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.

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2017 to primary completion in Feb 2022, 49 months.

Results were first posted in May 2023, 1 year 3 months after primary completion.

Of 134 non-industry phase 1/2 interventional studies under Leukemia, Myeloid, Acute, half reached primary completion within 76 months of starting (the median), counting those still running; a quarter within 49 and three quarters within 110. This study's 49 months is below that.

Counting every sponsor, half of 226 studies reached it within 73 months; a quarter within 48 and three quarters within 106.

How these figures are worked out, and which studies are left out of them.

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 Sep 5, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
