Clinical Study on the Use of Huaier Granules for the Treatment of Proteinuria Related to Bevacizumab and Anlotinib in Lung Cancer Patients

This study is a prospective, multicenter, parallel-controlled exploratory trial. It plans to enroll 40 subjects diagnosed with malignant lung tumors, who will visit the selected research centers from October 2025 to October 2026. All subjects will be assigned to either the control group or the experimental group based on clinical management and their own preference. Subjects in the control group will receive no therapeutic intervention, while those in the experimental group will be administered Huaier Granules.Throughout the study period, the planned duration for subject recruitment and enrollment is 12 months. The total follow-up duration for enrolled subjects is 48 weeks. After enrollment, subjects will be followed up every 2 weeks during the first 8 weeks, and then every 4 weeks thereafter. Follow-ups will continue until the study ends, the subject withdraws from the study for any reason, is lost to follow-up, or dies, whichever occurs first.
