Clinical Study of AL2846 Capsule in the Treatment of Differentiated Thyroid Cancer
Study Details
Study Description
Brief Summary
This is a Phase Ib clinical trial to evaluate the efficacy and safety of AL2846 capsule in iodine-refractory differentiated thyroid cancer that has failed previous TKI treatment. The trial is planned to enroll 20 subjects. The trial is a single-arm, multi-center, open label clinical study. Objective response rate (ORR) is the primary endpoint.

Outcome Measures
Primary Outcome Measures
- Objective remission rate (ORR) [From baseline up to 12 months.]
ORR is defined as the percentage of participants with complete remission (CR) and partial remission (PR) based on investigator records.
Secondary Outcome Measures
- Progression-free survival (PFS) [From baseline up to 12 months.]
PFS is defined as the time from randomization to the first recorded progressive disease (PD) or death from any cause.
- Disease control rate (DCR) [From baseline up to 12 months.]
DCR is defined as the percentage of patients who have achieved complete response, partial response and stable disease.
- Duration of remission (DoR) [From baseline up to 12 months.]
The time from the start of the first evaluation of the tumor as CR or PR to the first assessment as PD or death from any cause.
- Overall survival (OS) [From baseline to death event.]
Time from the first administration to death due to any cause.
- Occurrence of all adverse events (AEs) [From baseline to 28 days after the last dose or start of a new antineoplastic therapy (whichever comes first).]
Adverse events are evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Age: 18~80 years old (when signing the informed consent form), regardless of gender;
-
Differentiated thyroid carcinoma (DTC) confirmed by histopathology or cytology;
-
At least one measurable lesion according to Response Evaluation Criteria in Solid Tumours (RECIST 1.1);
-
Disease progression occurs after receiving at least one (but not more than two) Vascular Endothelial Growth Factor Receptor (VEGFR) targeted therapy in the past;
-
Iodine refractory patients can be defined as iodine refractory if they meet one of the following conditions:
-
The lesions showed no iodine uptake on the whole body imaging after 131I treatment, and could not benefit from the follow-up 131I treatment (it must be confirmed by the endocrinologist or nuclear medicine physician. If there are too many residual thyroid, it may affect the iodine uptake of the metastatic lesions, which can be evaluated when the thyroid is removed and treated again);
-
The lesions that originally took iodine gradually lost the ability to take iodine after 131I treatment;
-
Some lesions in the same patient take iodine, while some lesions do not take iodine, and there is no biochemical remission;
-
The focus takes iodine, but the disease progresses within 12 months (confirmed by imaging);
-
The cumulative dosage of 131I ≥ 600mCi or 22GBq, but the disease did not alleviate (confirmed by imaging).
-
There was evidence of imaging progress within 14 months before the knowledge;

-
HBsAg positive patients must meet the requirements of Hepatitis B Virus (HBV) DNA compliance or receive anti-HBV treatment at least one week before the start of the study, and the virus index is reduced by more than 10 times. At the same time, the patients are willing to receive anti-HBV treatment throughout the whole study period; The patients with hepatitis C antibody positive and Hepatitis B Virus (HCV) RNA quantitative positive should complete antiviral treatment at least 1 month before starting the study; 12) The serum Human Chorionic Gonadotropin (HCG) test of female patients of childbearing age must be negative within 7 days before study enrollment and must be non-lactating; The patient should agree to use contraception during the study period and within 6 months after the end of the study period; 13) The patient voluntarily joined the study and signed the informed consent form, with good compliance.
