Itacitinib in Treating Patients With Refractory Metastatic/Advanced Sarcomas

• Status: Recruiting
• Trial end date: 2024-06-01
• Target enrollment: 0
• Participant gender: All

Summary

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 cause changes in the immune system and the body's immune response to cancer, which may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Fred Hutchinson Cancer Research Center
• Collaborators: Incyte Corporation; National Cancer Institute (NCI)

Criteria

Inclusion Criteria:

• Must have a histologically confirmed diagnosis of sarcoma with one of the following subtypes:

• Cohort 1: Leiomyosarcoma

• Cohort 2: Undifferentiated pleiomorphic sarcoma

• Cohort 3: Synovial sarcoma or myxoid/round cell liposarcoma

• Cohort 4: Chondrosarcoma (all subtypes of chondrosarcoma are allowed)

• Subjects must have received at least two prior lines of systemic therapy

• All ongoing toxicities related to prior therapies must be resolved to grade 1 or better (except alopecia)

• Subjects must have one or more measurable lesions, as determined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 assessed by computed tomography (CT) or magnetic resonance imaging (MRI)

• Subjects must have at least one superficial lesion accessible for multiple biopsies; the tumor being biopsied cannot have been previously targeted for radiation therapy or have previously received intra-lesional treatment

• NOTE: Superficial lesions previously targeted with radiation therapy that have demonstrated significant new growth via radiological imaging may be targeted for biopsy, with sponsor-investigator approval.

• Total bilirubin level =< 1.5 x the upper limit of normal (ULN) range mg/dL

• Aspartate aminotransferase (AST) =< 2.5 x ULN and alanine aminotransferase (ALT) levels =< 2.5 x ULN

• Alkaline phosphatase < 2.5 x ULN

• Serum creatinine =< 1.5 x ULN

• Calculated creatinine clearance >= 30 mL/min using the Cockcroft-Gault formula may be included

• Absolute neutrophil count (ANC) >= 1.5 × 10^9/L

• Platelet count >= 100 x 10^9/L; transfusion is permitted as clinically indicated

• Hemoglobin >= 9 g/dL

• Transfusion is permitted as clinically indicated

• Subjects must have a life expectancy >= 6 months, as determined by the treating physician

• Eastern Cooperative Oncology Group (ECOG) performance status =< 2 or Karnofksy performance status >= 60

• Male or non-pregnant and non-breast feeding female:

• Females of child-bearing potential must agree to use highly effective contraception without interruption from initiation of therapy and while on study medication and have a negative serum pregnancy test (beta - human chorionic gonadotropin [hCG]) result at screening and agree to ongoing pregnancy testing during the course of the study, and at the end of study treatment; a highly effective method of contraception is defined as one that results in a low failure rate (that is, < 1% per year), when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some intrauterine contraceptive devices, sexual abstinence, or a vasectomized partner

• Male subjects must practice abstinence or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study

• Ability to understand and sign informed consent document

• Willingness and ability to comply with scheduled visits, laboratory tests, and other study procedures

Exclusion Criteria:

• Known active, uncontrolled, or symptomatic central nervous system (CNS) metastases; a subject with controlled and asymptomatic CNS metastases may participate in this study; as such, the subject must have completed any prior treatment for CNS metastases >= 28 days (including radiotherapy and/or surgery) prior to the start of treatment in this study and should not be receiving chronic corticosteroid therapy for CNS metastases; subjects with known CNS metastases must be confirmed radiographically stable by at least one imaging study, at least 28 days from last treatment

• Receipt of any type of cytotoxic, biologic, or other systemic anticancer therapy (including investigational) within 2 weeks of enrollment

• Prior treatment with a drug targeting JAK1, JAK1/2 or STAT3 inhibitor; Food and Drug Administration (FDA) approved small molecule tyrosine kinase inhibitors (TKIs) not specifically designed to target this pathway are okay (e.g. pazopanib, sunitinib, sorafenib)

• Known, active drug or alcohol abuse

• Pregnant or lactating females

• Active or recent infection requiring systemic anti-infective treatment that was completed =<14 days prior to enrollment (with the exception of uncomplicated urinary tract infection or upper respiratory infection)

• Uncontrolled or concurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

• Oral steroid usage within =< 14 days prior to enrollment

• Known inflammatory or autoimmune disease which requires patient to occasionally require high dose oral steroids

• Subjects with known, active human immunodeficiency virus (HIV) infection (subjects with undetectable viral load and normal CD4+ 1-cell count are permitted)

• Inability to swallow food or tablets, or significant gastrointestinal disorder that, in the opinion of the investigator, could interfere with absorption of the study drug

• Previous reaction to any component of itacitinib or known hypersensitivity to the active substance or any of the excipients

• Subjects with a sarcoma which has other, defined treatments or biology distinctly different from those of soft tissue sarcomas in general; including, but not limited to, Ewing's sarcoma, rhabdomyosarcoma, gastrointestinal stromal tumors, Kaposi's sarcoma, Wilm's tumor
