Summary

This phase I/II trial evaluates the best dose, side effects and possible benefit of CBL0137 in treating patients with solid tumors, including central nervous system (CNS) tumors or lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Drugs, such as CBL0137, block signals passed from one molecule to another inside a cell. Blocking these signals can affect many functions of the cell, including cell division and cell death, and may kill cancer cells.

Detailed description

PRIMARY OBJECTIVES: I. To estimate the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of Facilitates Chromatin Transcription (FACT) complex-targeting curaxin CBL0137 (CBL0137) administered via infusion on Day 1 and Day 8 of a 21-day cycle to children with recurrent or refractory solid tumors, including CNS tumors and lymphoma. (Phase 1 Dose Escalation) II. To preliminarily determine the antitumor effects as measured by objective response rate of CBL0137 in children with progressive/recurrent diffuse intrinsic pontine glioma (DIPG) and other H3 K27-altered diffuse midline gliomas (DMG). (Phase 2) SECONDARY OBJECTIVES: I. To preliminarily determine the antitumor effects of CBL0137 in children with refractory solid tumors and other CNS tumors, to the extent possible in the context of a Phase 1 study. II. To define and describe the toxicities of CBL0137 in children with recurrent or refractory solid tumors, including CNS tumors. III. To characterize the pharmacokinetics of CBL0137 in children with recurrent or refractory solid tumors, including CNS tumors. EXPLORATORY OBJECTIVES: I. To measure biologic marker FACT in tumor specimens with potential for correlation with disease response. II. To evaluate the effect of CBL0137 on immune response by measuring the effects on the interferon response pathway in peripheral blood mononuclear cells. III. To preliminarily determine the effect of treatment with CBL0137 on overall survival of children with DIPG or other diffuse midline gliomas, H3 K27-altered, in comparison with historical controls. OUTLINE: This is a phase I, dose-escalation study followed by a phase II study. Patients receive CBL0137 intravenously (IV) over 30 minutes on days 1 and 8. Treatment repeats every 21 days for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients with pseudoprogression may remain on treatment, as per the treating physician. Patients also undergo echocardiography (ECHO) collection of blood samples throughout the trial. Patients may also undergo bone marrow aspirate and/or biopsy as clinically indicated. After completion of study treatment, patients are followed up at 3, 6, 9, 12, 18, 24, 36, 48 and 60 months.
