Lantern Pharma secures US patent for LP-184 biomarker-guided cancer treatment
Lantern Pharma Inc. received USPTO approval for a patent covering LP-184 treatment guided by PTGR1, PTPN14, and ASPH biomarkers. The drug achieved a 45% disease control rate in Phase 1a trials for advanced solid tumors. Future Phase 1b/2 trials are planned for 2026, building on existing FDA Fast Track and Orphan Drug designations.

Lantern Pharma Inc. (NASDAQ: LTRN) has secured a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for U.S. Patent Application No. 17/230,821, strengthening its intellectual property portfolio for its lead candidate LP-184 (zirdafulven). The allowance covers methods for treating solid tumor cancers using illudins and specific biomarkers, specifically targeting patients with ovarian, primary liver, kidney, or thyroid cancer who exhibit elevated expression of the genes PTGR1, PTPN14, and ASPH. This regulatory validation underscores the company’s AI-driven approach to precision oncology, aiming to increase response likelihood by selecting patients based on distinct tumor biology features.
The patent approval follows clinical data from a completed 63-patient Phase 1a trial involving patients with recurrent or refractory advanced solid tumors. Among those treated at or above the effective therapeutic dose, LP-184 demonstrated a disease control rate of 45% (n = 29). Kishor Bhatia, Ph.D., Chief Scientific Officer of Lantern Pharma, noted that PTGR1 is unique as it is associated with aggressive tumor biology and serves as the enzyme that activates LP-184 inside the tumor cell. He added that combining it with PTPN14 and ASPH creates a selection signature leveraging additional tumor features, such as proliferation impact and parallel pathways conferring sensitivity to the drug.
Biomarker Selection and Mechanism
The allowed patent claims focus on a three-gene expression signature identified through Lantern’s proprietary RADR artificial intelligence platform. This platform utilizes machine learning and large-scale genomic data to identify biomarker signatures. The selected genes play critical roles in the drug’s mechanism of action:
| Gene | Role in LP-184 Sensitivity | Biological Impact |
|---|---|---|
| PTGR1 | Activates LP-184 prodrug inside tumor cells | Associated with aggressive tumor biology; frequently overexpressed in tumors |
| PTPN14 | Part of parallel pathways conferring sensitivity | Contributes to tumor aggressiveness and drug responsiveness |
| ASPH | Impacts proliferation | Linked to aggressive tumor characteristics |
LP-184 functions as a prodrug selectively activated by PTGR1, which is often overexpressed in tumors. Upon activation, it forms a highly reactive metabolite that damages cancer cell DNA, inducing interstrand cross-links and double-strand breaks. This damage cannot be repaired in tumors with deficient DNA damage repair (DDR) pathways, resulting in selective cancer-cell death while sparing normal cells. The RADR platform previously identified PTGR1 overexpression and low expression of multiple DDR genes as strong predictors of LP-184 sensitivity.
Clinical Development and Regulatory Status
Lantern Pharma plans to evaluate LP-184 in multiple precision oncology Phase 1b/2 clinical trials during 2026, focusing on advanced aggressive and rare cancers. The compound has already received significant regulatory recognitions, including FDA Fast Track Designation for triple-negative breast cancer (TNBC) and glioblastoma (GBM), as well as Orphan Drug Designation for malignant gliomas, pancreatic cancer, and atypical teratoid/rhabdoid tumor (ATRT). Preclinical models have demonstrated nanomolar potency, while early clinical testing has shown encouraging durability in heavily pre-treated patients.
Strategic Outlook
The company intends to continue expanding its patent portfolio through additional filings covering further indications and biomarker-guided applications of LP-184. This strategic move aims to protect its innovative approach to targeted cancer therapies, which leverages artificial intelligence to transform the cost, pace, and timeline of oncology drug discovery. By securing intellectual property rights for this specific biomarker combination, Lantern Pharma positions itself to potentially differentiate LP-184 in the competitive oncology landscape, offering a tailored treatment option for patients with specific genetic profiles in solid tumors.
How might the specific biomarker selection criteria (PTGR1, PTPN14, ASPH) impact the size of the addressable patient population for LP-184 in upcoming Phase 1b/2 trials?
What are the potential competitive risks to Lantern Pharma's IP moat if other oncology developers identify overlapping biomarker signatures or alternative activation mechanisms for illudin-based therapies?
Given the focus on rare and aggressive cancers, how could the FDA's Fast Track and Orphan Drug designations influence the timeline for regulatory approval and market exclusivity for LP-184?
