A Phase 1/2 interventional study of Biospecimen Collection and Dual X-ray Absorptiometry in Colorectal Carcinoma, Endometrial Carcinoma and Melanoma, sponsored by Children's Oncology Group. Recruiting at 21 sites in United States. Open to participants aged 12 Months to 30 Years. Per ClinicalTrials.gov, last updated 2026-08-25.
Sponsored by Children's Oncology Group · Phase 1/2, Interventional, and Treatment
This phase I/II trial evaluates the highest safe dose, side effects, and possible benefits of tegavivint in treating patients with solid tumors that has come back (recurrent) or does not respond to treatment (refractory). Tegavivint interferes with the binding of beta-catenin to TBL1, which may help stop the growth of tumor cells by blocking the signals passed from one molecule to another inside a cell that tell a cell to grow.
PRIMARY OBJECTIVES:
I. To estimate the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of tegavivint administered as an intravenous (IV) infusion over 4 hours, once weekly for 3 weeks, followed by a 1 week rest, in a 28-day cycle to pediatric patients with recurrent/refractory solid tumors, including non-Hodgkin lymphoma and desmoid tumors. (Phase 1 Dose Escalation) II. To preliminarily define antitumor activity of tegavivint in pediatric patients with recurrent or refractory Ewing sarcoma, liver tumors (hepatocellular carcinoma [HCC] and hepatoblastoma), osteosarcoma, Wilms tumor, desmoid tumors, and tumors with Wnt pathway aberrations. (Phase 2) III. To define and describe the toxicities of tegavivint administered on this schedule. (Phase I) IV. To characterize the pharmacokinetics of tegavivint in pediatric patients with recurrent or refractory cancer. (Phase I)
SECONDARY OBJECTIVE:
I. To preliminarily define the antitumor activity of tegavivint for pediatric patients with recurrent/refractory solid tumors, including lymphoma and desmoid tumors within the confines of a Phase 1 study.
EXPLORATORY OBJECTIVES:
I. To test whether baseline activity of the WNT/beta catenin pathway correlates with clinical response using archived tumor tissue.
II. To characterize pharmacodynamic changes in tumor tissue to examine target engagement by tegavivint.
III. To characterize pharmacodynamic activity of tegavivint on serum protein biomarkers.
OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.
Patients receive tegavivint IV over 4 hours on days 1, 8, and 15 of each cycle. Treatment repeats every 28 days for up to 26 cycles or 24 months in the absence of disease progression or unacceptable toxicity. Patients undergo an x-ray at baseline, after cycle 1, and then every 3 cycles while on treatment and a dual x-ray absorptiometry (DEXA) scan at baseline, every 6 cycles while on treatment, at months 12 and 24, and then annually up to 60 months following end of therapy. Patients may also undergo blood sample collection throughout the trial.
After completion of study intervention, patients are followed up every 3 months for 12 months, every 6 months for 24 months, and then annually for 60 months.

Patients must have fully recovered from the acute toxic effects of all prior anti-cancer therapy and must meet the following minimum duration from prior anti-cancer directed therapy prior to enrollment. If after the required timeframe, the numerical eligibility criteria are met, e.g., blood count criteria, the patient is considered to have recovered adequately.
Cytotoxic chemotherapy or other anti-cancer agents known to be myelosuppressive
Non-Hodgkin lymphoma patients

Exclusion Criteria:
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: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
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.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
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.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
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.
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 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.
After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.
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).
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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.
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.
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.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask 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.
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.
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.

Tegavivint will be administered IV over 4 hours on days 1, 8, and 15 of each cycle. Administer D5W flush after completion of each tegavivint infusion. Treatment repeats every 28 days for up to 26 cycles or 24 months in the absence of disease progression or unacceptable toxicity. Drug doses should be adjusted based on the weight (height and BSA will also be captured) measured within 7 days prior to the beginning of each cycle. The starting dose will be 5 mg/kg with dose levels for subsequent cohorts increasing to 6.5 mg/kg and 8 mg/kg if excessive toxicity does not occur. If the MTD has been exceeded at the first dose level, then the subsequent cohort of patients will be treated at a dose of 4 mg/kg. Patients undergo an x-ray at baseline, after cycle 1, and then every 3 cycles while on treatment and DEXA scan at baseline and every 6 cycles while on treatment, then at 12 months, 24 months, and annually up to 60 months following end of therapy.
