Last Updated: 2025-06-11

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE2
• Total Enrollment: 33 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-06-06
• Study Completion Date: 2030-09-11

Brief Summary

This phase II trial tests how well XL092 works for the treatment of patients with differentiated thyroid cancer that has not responded to previous treatment with radioiodine (radioiodine refractory) and that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). XL092 is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply, which may help keep cancer cells from growing.

Detailed Description

PRIMARY OBJECTIVE:

I. Assess efficacy of the treatment zanzalintinib (XL092) in radioiodine refractory/radioactive iodine refractory (RAIR) differentiated thyroid cancer (DTC) patients by evaluating the proportion of patients alive and without progression at 12 months.

SECONDARY OBJECTIVES:

I. Assess efficacy of XL092 treatment in RAIR DTC patients by imaging. II. Assess efficacy of the treatment XL092 in RAIR DTC patients by evaluating progression free survival.

III. Assess efficacy for RAIR DTC patients treated with XL092 evaluating the overall survival time.

IV. Assess the safety and tolerability of XL092 monotherapy in patients with RAIR DTC.

V. Characterize the quality of life in RAIR DTC patients treated with XL092 monotherapy.

EXPLORATORY OBJECTIVES:

I. Assess immune cell landscape in XL092 treated patients. II. Assess by next generation sequencing (NGS) and biomarker analysis, mechanisms that lead to response or failure to XL092.

OUTLINE:

Patients receive XL092 orally (PO) daily (QD) on days 1-21 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scan or magnetic resonance imaging (MRI) and x-ray imaging, and blood and urine sample collection throughout the study.

After completion of study treatment, patients are followed up at 30 days then every 3 months for 12 months.

Eligibility Criteria

Inclusion Criteria

• NOTE: RAI refractoriness is defined as absence of uptake of RAI on either a low-dose diagnostic test or a post-treatment RAI scan in measurable lesions or radiographic progression of disease within 12 months of the last course of RAI treatment despite the recorded uptake of RAI with that previous therapy or having a cumulative lifetime administered dose of ≥ 600mCi.
• Poorly differentiated thyroid cancer (PDTC) is typically classified as a type of differentiated thyroid cancer (as opposed to undifferentiated thyroid cancer or anaplastic thyroid cancer)

• For patients with a known history of human immunodeficiency virus (HIV), infected patients on effective anti-retroviral therapy must have a viral load undetectable for 6 months prior to registration. Please note this lab is not a requirement for eligibility, however, if it has been completed previously as part of the patient's health care, it should be documented for eligibility.

• NOTE. To be eligible, patients must not have known uncontrolled infection with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS)-related illness
• NOTE: patients must meet all of the following criteria:

• On stable anti-retroviral therapy
• CD4+ T cell count ≥ 200/µL; and
• An undetectable viral load.
• NOTE: HIV testing will be performed at screening if it is required by local regulation or per standard of care (SOC).
• NOTE: To be eligible, patients taking CYP inhibitors (e.g., zidovudine, ritonavir, cobicistat, didanosine) or CYP3 inducers (efavirenz) must change to a different regimen not including these drugs 7 days prior to initiation of study treatment. Anti-retroviral therapies (ART) must have been received for at least 4 weeks prior to the first dose.
• NOTE: CD4+ T cell counts, and viral load are monitored per standard of care by the local health care provider
• Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression and patients are stable for at least 4 weeks before the first dose of study treatment.

• NOTE: Patients with active brain metastases are not allowed.
• NOTE: Therapeutic doses of Low Molecular Weight Heparin (LMWH) are not permitted in patients with known brain metastases
• Patients of child-bearing potential must have a negative pregnancy test prior to registration on study.

• NOTE: Patients of child-bearing potential are considered to be of child-bearing potential unless one of the following criteria are met: documented permanent sterilization (hysterectomy, bilateral salpingectomy, or bilateral oophorectomy) or documented postmenopausal status (defined as 12 consecutive months of amenorrhea in a patient of child-bearing potential > 45 years-of-age in the absence of other biological or physiological causes). In addition, a patient of child-bearing potential < 55 years-of-age must have a serum follicle stimulating hormone (FSH) level > 40 mIU/mL to confirm menopause)
• The effects of XL092 on the developing human fetus are unknown. For this reason and because tyrosine kinase inhibitors (TKIs) as well as other therapeutic agents used in this trial are known to be teratogenic, sexually active fertile patients and their partners must agree to use highly effective methods of contraception during the course of the study and for the following durations after the last dose of study treatment (whichever is later): Through 186 days after the last dose of XL092 for patients of child-bearing potential or through 96 days after the last dose of XL092 for patients of sperm producing capacity. Because the effect of XL092 on the pharmacokinetics (PK) of contraceptive steroids has not been investigated, hormonal contraceptives may not achieve the level considered "highly effective". For this reason, an additional contraceptive method, such as a barrier method (e.g., condom), may be required. In addition, patients of sperm producing capacity must agree not to donate sperm and patients of child-bearing potential must agree not to donate eggs (ova, oocyte) for the purpose of reproduction during these same periods. Should a patient of child-bearing potential become pregnant or suspect they are pregnant while they or their partner are participating in this study, they should inform their treating physician immediately
• Recovery to baseline or ≤ grade 1 per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5 from adverse events (AE[s]) related to any prior treatments unless AE(s) are deemed clinically nonsignificant by the Treating Investigator and/or stable on supportive therapy.

• NOTE: Patients must have recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) except for alopecia, neuropathy, and other non-significant adverse events per NCI CTCAE v 5.0
• Patients must have the ability to understand and the willingness to sign a written informed consent document and comply with the protocol requirements
• Patients must have the ability to swallow, retain and absorb oral medications

• NOTE: Patients must have the ability to swallow tablets or ingest a suspension either orally or by a nasogastric (NG) or gastrostomy (PEG) tube

• Patient is pregnant or nursing (lactating)

• NOTE: Pregnant patients are excluded from this study because XL092 is a tyrosine kinase inhibitor with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with XL092, breastfeeding should be discontinued if the mother is treated with XL092
