Thyroxine Replacement Therapy After Lobectomy for Low-risk Papillary Thyroid Carcinoma

Q: Who can participate in NCT06087068?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT06087068?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: 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.

A Prospective, Single-arm Phase II Study of Thyroxine Replacement Therapy After Lobectomy for Low-risk Papillary Thyroid Carcinoma

Thyroxine Replacement Therapy After Lobectomy for Low-risk Papillary Thyroid Carcinoma (NCT06087068) is a Phase 2 interventional studying Thyroid Cancer and Surgery, sponsored by Cancer Institute and Hospital, Chinese Academy of Medical Sciences. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

Papillary thyroid carcinoma (PTC) is the most common thyroid cancer and has a good prognosis.According to the 2015 American thyroid association (ATA) guidelines, no gross extrathyroidal extension and the number of pathological lymph node micrometastases (\<0.2cm) ≤5 were defined as the low recurrence risk group. After total thyroidectomy and radioiodine treatment, the probability of disease-free status (irritant Tg\<1ng/ml, no evidence of other disease recurrence) is about 78%-91%, and the probability of structural recurrence is about 1%-10%. In recent years, due to the further understanding of PTC, surgeons tend to become more conservative in treatment, such as active observation or reducing the extent of surgery. The indication for lobectomy has been extended to tumors \<4cm without extrathyroidal extension and clinical lymph node metastasis. For patients treated with lobectomy, current guidelines recommend that Thyroid Stimulating Hormone (TSH) be controlled at 0.5-2 mU/L, but evidence on the prognostic benefits of this TSH inhibition range is lacking.In recent years, a number of studies have suggested that if postoperative TSH in low-risk patients after lobectomy is acceptable within the reference range, it means that a considerable number of patients have a high probability of not receiving thyroxine replacement therapy after surgery, which can significantly improve their quality of life.A previous retrospective study from our institute showed no significant association between TSH levels after lobectomy and prognosis.The aim of this study was to evaluate the benefits and risks of postoperative TSH levels within the reference range (0.4-5 mU/L) in patients with low-risk papillary thyroid cancer who underwent lobectomy.In order to improve the effect of longer recurrence and death time of PTC, the investigators also performed postoperative thyroglobulin and its antibody for short-term treatment response evaluation.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Thyroid Cancer and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

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.

Target enrollment of 140 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Thyroid Cancer subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - (1) Age 18-70 years old, ECOG score 0-2; - (2) Patients with the maximum diameter of unilateral thyroid nodules ≤4.0cm by ultrasound, papillary thyroid carcinoma diagnosed by preoperative cytology (Bethesda grade VI) or intraoperative freezing, and planned to undergo thyroid lobectomy; - (3) No clinical lymph node metastasis (cN0);No extrathyroidal extension, and the number of pathological lymph node micrometastasis (\<0.2cm) was ≤5. - (4) no serious medical diseases and major organ dysfunction, such as blood routine, liver, kidney, heart, lung function; No previous history of other head and neck malignancies, no history of neck radiation, no history of deep neck surgery (skin mass excision except clinical); - (5) Fully understand this study, have the ability to complete treatment, have follow-up conditions and voluntarily sign willing to sign a consent form. Who Should NOT Join This Trial: - (1) History of malignancy in other sites (previous or simultaneous), excluding curable non-melanoma skin cancer and cervical carcinoma in situ; - (2) The contralateral thyroid nodules were evaluated by preoperative ultrasound, and the patients with suspicious nodules who underwent fine-needle aspiration cytology and could not confirm the benign or malignant nodules (Bethesda grade I, III-V) were excluded. - (3) Cervical lymph node metastasis was evaluated before surgery. Cytological aspiration and Tg eluent determination were performed on suspicious lymph nodes. If cytology was negative and Tg eluent was not higher than the normal range, it was not considered as exclusion criteria. The patients who were sent for intraoperative examination and showed metastasis were excluded. - (4) cytological aspiration or intraoperative freezing suspected non-papillary thyroid carcinoma (follicular carcinoma, medullary carcinoma, poorly differentiated or undifferentiated carcinoma) or high-risk subtypes of papillary thyroid carcinoma (high cell type); ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.
