XL092 and Cemiplimab in BRAF WT Thyroid Cancer (NCT06902376) is a Phase 1 interventional studying Anaplastic Thyroid Cancer and Thyroid Cancer, sponsored by UNC Lineberger Comprehensive Cancer Center. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Anaplastic Thyroid Cancer, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 12 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: - Written willing to sign a consent form was obtained to participate in the study and HIPAA authorization for the release of personal health information. - Subjects are willing and able to comply with study procedures based on the judgment of the investigator. - Age ≥ 18 years at the time of consent. - the Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2. - Pathologic findings supporting the clinical impression of anaplastic thyroid cancer. Terminology consistent or suggestive of diagnosis may include the following: anaplastic thyroid carcinoma, undifferentiated carcinoma, squamous carcinoma; carcinoma with spindled, giant cell, or epithelial features; poorly differentiated carcinoma with pleomorphism, extensive necrosis with tumor cells present. - Subject is willing to have a fresh biopsy at least 3 days prior to neoadjuvant therapy if archival tissue is unavailable. Also willing to have a biopsy at the time of SOC surgery, if applicable. - Must have BRAF V600E mutation-negative tumor, as determined by BRAF V600E immunohistochemistry on tumor tissue or genetic/molecular testing of the tumor. Who Should NOT Join This Trial: - Pregnant or breastfeeding (Note: breast milk cannot be stored for future use while the mother is being treated on the study). Females should not breastfeed while receiving study treatment and for 1 month from the last dose of XL092. - Patients who have had prior exposure to any immune modulating agents or any type of small molecule kinase inhibitor (including investigational agents) and have documented disease progression on these agents will not be eligible. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

The following are not exclusionary: vitiligo, childhood asthma that has resolved, type 1 diabetes, residual hypothyroidism that required only hormone replacement, or psoriasis that does not require systemic treatment. * Subject history of documented allergic reactions or acute hypersensitivity reactions attributed to antibody treatments. * Subject is receiving prohibited medications or treatments as listed in the protocol that cannot be discontinued/replaced by an alternative therapy within 7 days of initiating treatment. * Participation in another clinical study with an investigational product during the last 3 weeks.

Bring the printable summary of this trial — including the NCT ID (NCT06902376), the sponsor (UNC Lineberger Comprehensive Cancer Center), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Frequently Asked Questions

What is the NCT06902376 clinical trial studying?

This multicenter study examines the safety and feasibility of the combination of neoadjuvant XL092 and cemiplimab prior to surgical resection in participants with wild-type (WT) anaplastic thyroid cancer (ATC) that has a BRAF mutation (BRAF V600E). The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT06902376?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
