Lantern Pharma (NASDAQ: LTRN) has achieved a milestone in developing a qRT-PCR-based diagnostic for its drug candidate, LP-184. This diagnostic quantifies PTGR1 RNA in tumor samples, helping identify patients likely to respond to LP-184 across various solid tumors. Successful confirmation of PTGR1 as a important biomarker paves the way for further assay validation and eventual use in later-stage clinical trials. Studies have shown that incorporating biomarkers like PTGR1 can significantly enhance clinical trial success rates. LP-184, aimed at treating malignant gliomas, pancreatic cancer, and ATRT, holds both Orphan Drug and Rare Pediatric Disease designations from the FDA.
