Brief Summary:
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.

Detailed Description:

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.

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.

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.

Arm Intervention/treatment
Experimental: Treatment (tegavivint)
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.
