Clinical Trial Summary

This phase II Pediatric MATCH trial studies how well erdafitinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with FGFR mutations that have spread to other places in the body and have come back or do not respond to treatment. Erdafitinib may stop the growth of cancer cells with FGFR mutations by blocking some of the enzymes needed for cell growth.

Description:

PRIMARY OBJECTIVE: I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with erdafitinib with advanced solid tumors (including central nervous system [CNS] tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor genetic alterations in the FGFR1/2/3/4 pathway. SECONDARY OBJECTIVES: I. To estimate the progression free survival in pediatric patients treated with erdafitinib with advanced solid tumors (including CNS tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor genetic alterations in the FGFR1/2/3/4. II. To obtain information about the tolerability of erdafitinib in children with relapsed or refractory cancer. III. To provide preliminary estimates of the pharmacokinetics of erdafitinib in children with relapsed or refractory cancer. EXPLORATORY OBJECTIVE: I. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA). OUTLINE: Patients receive erdafitinib orally (PO) once daily (QD) on days 1-28 of each cycle. Treatment repeats every 28 days for up to 26 cycles (2 years) in the absence of disease progression or unacceptable toxicity. Patients undergo an x-ray, computed tomography (CT) scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, radionuclide imaging, and/or bone scan, as well as a bone marrow aspiration and/or biopsy during screening and on study. Patients also undergo blood sample collection on study. After completion of study treatment, patients are followed up periodically.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Changes in tumor genomic profile	A descriptive analysis will be performed and will be summarized with simple summary statistics. All of these analyses will be descriptive in nature.	Up to 3 years
Primary	Response rate	Response rates will be calculated as the percent of evaluable patients who are responders, and confidence intervals will be constructed using the Wilson score interval method.	From enrollment to the end of treatment, up to 2 years
Secondary	Incidence of adverse events	Graded by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Toxicity tables will be constructed to summarize the observed incidence by type of toxicity and grade. A patient will be counted only once for a given toxicity for the worst grade of that toxicity reported for that patient.	From enrollment to the end of treatment, up to 2 years
Secondary	Progression free survival (PFS)	PFS along with the confidence intervals will be estimated using the Kaplan-Meier method.	From the initiation of protocol treatment to the occurrence of any of the following events: disease progression or disease recurrence or death from any cause, assessed up to 3 years
Secondary	Pharmacokinetic (PK) parameters	A descriptive analysis of PK parameters will be performed to define systemic exposure, drug clearance, and other pharmacokinetic parameters. The PK parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).
