Patients receive itacitinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Itacitinib

Laboratory Biomarker Analysis

Lee Cranmer

This pilot phase I trial studies how well itacitinib works in treating patients with sarcomas that do not respond to treatment (refractory) and have spread to other parts of the body (advanced/metastatic). Itacitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

OUTLINE:

Patients receive itacitinib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 7 and 30 days, every 12 weeks from baseline for up to 1 year, and then every 6 months thereafter.

Itacitinib in Treating Patients With Refractory Metastatic/Advanced Sarcomas

A Pilot Study Examining the Impact of the Jak1 Inhibitor Itacitinib on the Sarcoma Tumor Immune Microenvironment

Evaluation of the change in percentages of cells against the null hypothesis of no difference will be performed using a 1-sided t-test at the 0.05 level.

Will be graded according to Common Terminology Criteria for Adverse Events version 5.0. The frequency and severity of toxicities will be evaluated by proportions and associated 95% confidence intervals.

Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Distributions and percentages at landmark times for time to event outcomes will be estimated using the method of Kaplan-Meier. Confidence intervals about medians will be estimated using the method of Brookmeyer-Crowley. With 12 LMS patients, binary proportions can be estimated to within 29% with 95% confidence. With 8 (SS or MRCL) and PUS, respectively, binary proportions can be estimated to within 36% with 95% confidence.
