About
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.
Full 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.
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.

Inclusion criteria
PART A: Patients must be >= 12 months and =< 21 years of age at the time of study enrollment
PART B: Patients must be >= 12 months and =< 30 years of age at the time of study enrollment
Patients with recurrent or refractory solid tumors including non-Hodgkin lymphoma and desmoid tumors are eligible. Patients must have had histologic verification of malignancy at original diagnosis or relapse
PART A: Patients with relapsed or refractory solid tumors, including patients with non-Hodgkin lymphoma and desmoid tumors
PART B: Patients with recurrent or refractory Ewing sarcoma, desmoid tumors, osteosarcoma, liver tumors (HCC and hepatoblastoma), Wilms tumor, and tumors with Wnt pathway aberrations. For the Wnt pathway aberrations cohort we will include the most common CTNNB1 mutations (S37F, S45F, T41A, S45P, S33C, S37C, D32Y, S33F, T41I, G34R, G34V, D32N, S33P, G34E, D32G) as well as any loss of function mutations in the APC, Axin2FBXW7, TCF7L2, and RNF43 genes or any gain-of-function mutations in the GSK3B, LRP6, and LGR5 genes. For patients without prior sequencing, immunohistochemistry (IHC), is required. IHC showing strong nuclear beta-catenin staining will be accepted for the following tumor types: colorectal carcinoma, melanoma, endometrial cancer, ovarian cancer, neuroblastoma, non-Hodgkin lymphoma, pancreatic ductal adenocarcinoma, and solid pseudopapillary tumor of the pancreas
PART A: Patients must have either measurable or evaluable disease. For desmoid tumors, the patient must have disease that the investigator deems unresectable or sufficiently morbid or potentially life-threatening that there is favorable risk/benefit to the patient to participate in the trial
PART B: Patients must have measurable disease. For desmoid tumors, the patient must have measurable disease that the investigator deems unresectable or sufficiently morbid or potentially life-threatening that there is favorable risk/benefit to the patient to participate in the trial
Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1 or 2. Use Karnofsky for patients > 16 years of age and Lansky for patients =< 16 years of age
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
Solid tumor patients: >= 21 days after the last dose of myelosuppressive chemotherapy (42 days if prior nitrosourea)
Non-Hodgkin lymphoma patients
Anti-cancer agents not known to be myelosuppressive (e.g., not associated with reduced platelet or absolute neutrophil counts [ANC]): >= 7 days after the last dose of agent
Antibodies: >= 21 days must have elapsed from infusion of last dose of antibody, and toxicity related to prior antibody therapy must be recovered to grade =< 1
Corticosteroids: If used to modify immune adverse events related to prior therapy, >= 14 days must have elapsed since last dose of corticosteroid
Hematopoietic growth factors: >= 14 days after the last dose of a long-acting growth factor (e.g., pegfilgrastim) or 7 days for short acting growth factor. For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur
Interleukins, interferons and cytokines (other than hematopoietic growth factors): >= 21 days after the completion of interleukins, interferon or cytokines (other than hematopoietic growth factors)

Patients must not have received prior exposure to tegavivint

Patients with known bone marrow metastatic disease will be eligible for study provided they meet blood counts (may receive transfusions provided they are not known to be refractory to red cell or platelet transfusions). These patients will not be evaluable for hematologic toxicity. At least 5 of every cohort of 6 patients must be evaluable for hematologic toxicity for the dose-escalation part of the study. If dose-limiting hematologic toxicity is observed, all subsequent patients enrolled on Part A must be evaluable for hematologic toxicity
