A Phase 3 interventional study of Biospecimen Collection and Computed Tomography in Resectable Liposarcoma, Resectable Soft Tissue Sarcoma and Resectable Undifferentiated Pleomorphic Sarcoma, sponsored by Ohio State University Comprehensive Cancer Center. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-16.
Sponsored by Ohio State University Comprehensive Cancer Center · Phase 3, Interventional, and Treatment
This phase III trial compares the effect of adding doxorubicin and ifosfamide (AIM chemotherapy) before (neoadjuvant) receiving standard treatment with pembrolizumab, radiation therapy and surgery to standard of care treatment alone in treating patients with high-risk soft-tissue sarcomas, such as undifferentiated pleomorphic sarcoma (UPS) or liposarcoma (LPS), that originate in the arms, legs (extremity) or torso (trunk wall) and can be removed by surgery (resectable). Doxorubicin comes from the bacterium Streptomyces peucetius. It damages deoxyribonucleic acid (DNA) and may kill tumor cells. It is a type of anthracycline antitumor antibiotic. Ifosfamide attaches to DNA in cells and may kill tumor cells. It is a type of alkylating agent and a type of antimetabolite. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Intensity-modulated radiation therapy (IMRT)is a type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. Giving neoadjuvant doxorubicin and ifosfamide with standard of care pembrolizumab, radiation therapy and surgery may be safe, tolerable, and/or more effective than standard of care therapy alone in treating patients with high-risk resectable soft tissue sarcoma of the arms, legs, or torso.
PRIMARY OBJECTIVE:
I. Disease-free survival (DFS).
SECONDARY OBJECTIVES:
I.Patient-reported quality of life (QoL). II. Overall survival (OS). III. Loco-regional DFS. IV. Distant DFS. V. Treatment-related adverse events (TRAEs).
EXPLORATORY OBJECTIVES:
I. To evaluate DFS between study arms in patients stratified by estimated 10-year (yr) OS (\< 60% versus [vs] ≥ 60%) as determined by SARCULATOR nomogram.
II. To characterize the immune micro-environment of UPS and LPS prior to treatment and after neoadjuvant treatment.
III. To identify factors associated with pathologic response to neoadjuvant therapy.
IV. To compare surgical outcomes between arms, including percentage of patients who successfully undergo protocol-defined surgical resection, rate of R0 vs ≥ R1 resection, rate of re-resection, and surgical complication rates.
V. To identify factors associated with DFS. VI. To identify circulating biomarkers associated with response to treatment and risk of recurrence.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A:
NEOADJUVANT: Patients receive doxorubicin intravenously (IV) within 72 hours on day 1 and ifosfamide IV on days 1-3 or on days 1-5 of each cycle. Cycles repeat every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Starting 21 days after completing neoadjuvant chemotherapy with AIM, patients receive standard of care pembrolizumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Starting 4 weeks after beginning last cycle of AIM, patients also undergo IMRT once daily (QD) on Monday-Friday (5 days per week) for up to 25 fractions (5 weeks) per standard of care. Starting 4-6 weeks after completing radiation therapy, patients undergo oncologic resection per standard of care.
POST-SURGERY: Starting 1-4 weeks after surgery, patients receive pembrolizumab IV over 30 minutes on day 1 of each cycle per standard of care. Cycles repeat every 21 days for cycles 4-17 in the absence of disease progression or unacceptable toxicity.
Additionally, patients undergo transthoracic echocardiography (TTE) or multigated acquisition scan (MUGA) at screening, and blood sample collection, computed tomography (CT) and magnetic resonance imaging (MRI) throughout the study.
ARM B:
NEOADJUVANT: Patients receive standard of care pembrolizumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Starting on day 8, patients undergo radiation therapy, patients undergo IMRT QD on Monday-Friday (5 days per week) for up to 25 fractions (5 weeks) per standard of care. Starting 4-6 weeks after completing radiation therapy, patients undergo oncologic resection per standard of care.
POST-SURGERY: Starting 1-4 weeks after surgery, patients receive pembrolizumab IV over 30 minutes on day 1 of each cycle per standard of care. Cycles repeat every 21 days for cycles 4-17 in the absence of disease progression or unacceptable toxicity.
Additionally, patients undergo TTE or MUGA at screening, and blood sample collection, CT and MRI throughout the study.
After completion of study treatment, patients are followed every 12 weeks (3 months) for 2 years then every 24 weeks (about every 6 months) through year 5.

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 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.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
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).
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 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.
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.
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.
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.
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 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.
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.
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.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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.
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.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
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.
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.
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.
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.
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.
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.
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.

Disease-free survival (DFS)
DFS will be estimated using the Kaplan-Meier method and compared between treatment groups using the stratified log-rank test. In addition, a Cox proportional hazards model will be used to estimate the hazard ratio and 95% confidence interval, adjusting for relevant covariates.
Time frame: From randomization to disease recurrence of death, whichever occurs first, assessed up to 2 years
Patient-reported quality of life (QOL)
Will be evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30. A linear mixed-effects model will be used to assess changes in QOL over time, including random intercepts and slopes. The model will incorporate treatment group, time, baseline QOL score, and the treatment-by-time interaction as covariates.
Time frame: At baseline and at 1 and 2 years post-randomization
Overall survival (OS)
Will be estimated using the Kaplan-Meier method and compared between treatment groups using the log-rank test. A Cox proportional hazards model will also be used to evaluate OS, adjusting for relevant covariates.
Time frame: From randomization to death from any cause, assessed up to 5 years
Loco-regional DFS
Will be defined as clinical or biopsy-confirmed recurrence at the primary tumor site, regional nodal involvement, and loco-regional relapse. Will be estimated using the Kaplan-Meier method and compared between treatment groups using the log-rank test. A Cox proportional hazards model will also be used to evaluate loco-regional DFS, adjusting for relevant covariates.
Time frame: Up to 5 years
Distant DFS
Will be defined as clinical or biopsy-confirmed recurrence at a distant site distinct from the primary tumor site. Will be estimated using the Kaplan-Meier method and compared between treatment groups using the log-rank test. A Cox proportional hazards model will also be used to evaluate distant DFS, adjusting for relevant covariates.
Time frame: Up to 5 years
Incidence of treatment-related adverse events (TRAEs)
Will be measured using Common Terminology Criteria for Adverse Events version 6. The rate of TRAEs will be calculated as the number of patients who develop TRAEs divided by the total number of eligible and evaluable patients. The frequency and severity of TRAEs will be collected and summarized by descriptive statistics. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns.
Time frame: Up to 5 years
Start is estimated for Dec 2026; primary completion for Dec 2028, 24 months later.
