Rucaparib Monoclonal Antibody for Lorlatinib-Induced Hypercholesterolemia / Mixed

This prospective single-arm clinical study plans to enroll 29 participants with unresectable stage IIIB-IV ALK fusion-positive non-small cell lung cancer (NSCLC). Eligible patients must be aged ≥18 years with an ECOG performance status of 0-2 and have developed grade 1-3 hypercholesterolemia adverse events (AEs, per CTCAE 5.0) after lorlatinib treatment. All subjects will receive recakimab 300 mg administered once every 8 weeks. The primary endpoint is the percentage change from baseline in low-density lipoprotein cholesterol (LDL-C) at week 16. Secondary endpoints include absolute change in LDL-C at week 16; percentage and absolute change in LDL-C at week 32; percentage and absolute changes from baseline in non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B (ApoB), total cholesterol/HDL-C ratio, ApoB/apolipoprotein A1 (ApoA1) ratio, lipoprotein(a) \[Lp(a)\] and triglycerides (TG) at weeks 16 and 32; proportion of patients whose hypercholesterolemia AEs return to normal at weeks 16 and 32; LDL-C target achievement rate at weeks 16 and 32; and safety profile related to recakimab.
