Real-world Study of Lenalidomide After First-line Treatment Lenvatinib With PD-1 in Advanced HCC

HCC - Hepatocellular Carcinoma

Lenalidomide, hepatocellular carcinoma

This study is a real-world, single-arm, observational study primarily collecting data on patients with hepatocellular carcinoma who experienced disease progression after receiving lenvatinib in combination with PD-1 inhibitors as part of routine clinical practice, and evaluating the efficacy of adding lenalidomide to their treatment regimen.

This study is a real-world, single-arm, observational study primarily collecting data on patients with hepatocellular carcinoma who experienced disease progression after receiving lenvatinib in combination with PD-1 inhibitors as part of routine clinical practice, and evaluating the efficacy of adding lenalidomide to their treatment regimen. The treatment drugs used in this study are: Lenvatinib mesylate capsules (imported or domestically produced), immunotherapy: PD-1 inhibitors (approved for marketing in China and abroad), and Lenalidomide capsules. The study population was divided into three groups: 1. Patients with advanced, unresectable hepatocellular carcinoma treated with lenvatinib in combination with a PD-1 inhibitor, who showed imaging evidence of disease progression (defined as an increase in the maximum diameter of the primary tumor by more than 20% or the emergence of new lesions) and were planned to receive additional treatment with lenalidomide; 2. Patients currently receiving lenvatinib plus PD-1 inhibitor plus lenalidomide therapy due to disease progression; 3. Patients who have previously received lenvatinib plus PD-1 inhibitor plus lenalidomide therapy; Participants in categories 1 and 2 will sign an informed consent form and be enrolled in this study for symptomatic treatment. Category 3 study participants, who have previously received this treatment regimen, cannot obtain informed consent. Therefore, this study has applied for informed consent waiver for Category 3 study participants (this option is not available in the reporting system). According to standard clinical treatment principles, collect hematological examination data from patients one week and one month after receiving combination therapy with lenvatinib + PD-1 inhibitor + lenalidomide.Collect hematological and imaging examination data two months after combination therapy, and evaluate the imaging data at the two-month mark to determine whether the tumor has progressed.Each observation cycle lasts two months. Enrollment standard： 1.Age ≥ 18 years old 2.Patients with hepatocellular carcinoma who previously received lenvatinib and PD-1 inhibitors and whose tumors progressed on imaging (enhanced MRI, enhanced CT, or PET-CT) were treated with lenalidomide. 3.Expected survival period exceeding 3 months 4.Patients with a history of other malignant tumors who have been disease-free for more than 2 years after initial treatment (such as non-melanoma skin cancer or cervical carcinoma in situ) 5.Participants of childbearing age agreed to use contraception during the study period Exclusion standard： 1. Fibrous plate layer or sarcomatous HCC or mixed type HCC-ICC 2. Currently participating in and receiving other experimental treatments, or participating in an immune checkpoint inhibitor study and receiving study treatment. 3. Previously underwent solid organ transplantation, diagnosed with immunodeficiency 4. Bleeding from esophageal or gastric varices within 3 months prior to enrollment 5. Hepatic encephalopathy in the past 6 months, or obvious ascites at the time of enrollment. 6. Active infection requiring systemic treatment 7. CTCAE grading Platelet count \< 50 × 10⁹/L or neutrophil count \< 1 × 10⁹/L 8. Pregnant or breastfeeding women 9. Patients with myocardial ischemia or myocardial infarction classified as grade II or higher according to the Common Terminology Criteria for Adverse Events (CTCAE), uncontrolled arrhythmia 10. Patients who have previously used pomalidomide or thalidomide 11. Patients who have previously received CTLA-4 in combination with PD-1/PD-L1 inhibitors 12.
