On April 1, 2021 Lantern Pharma Inc. (NASDAQ: LTRN), a clinical stage biopharmaceutical company using its proprietary RADR artificial intelligence ("A.I.") platform to transform oncology drug discovery and development, reported a collaboration with Johns Hopkins Pediatric Oncology Division of The Sidney Kimmel Comprehensive Cancer Center and Dr. Eric Raabe, M.D., Ph.D. focused on Lantern’s drug candidate LP-184 in the area of brain tumors, and specifically in Atypical Teratoid Rhabdoid Tumors ("ATRT"), an ultra-rare and fast-growing cancerous tumor of the brain that presents primarily in children (Press release, Lantern Pharma, APR 1, 2021, View Source [SID1234577504]).

"As we enriched our RADR A.I. platform for additional cancer indications, we began to discover common molecular pathways that drive response to our drug candidate, LP-184, across multiple additional CNS cancers," stated Panna Sharma, President and CEO of Lantern Pharma. "Chief among these newly identified CNS cancers was ATRT, an ultra-rare and fast-growing cancerous tumor of the brain that presents primarily in children with no effective therapies. The urgency of directing LP-184 towards helping children battle this particularly aggressive cancer was self-evident, as was the opportunity to collaborate with the Johns Hopkins’ pediatric oncologist, Dr. Eric Raabe, who has devoted his career to studying pediatric brain cancers, including ATRT."
Rhabdoid tumors (RTs) can emerge in the brain, kidneys, liver and all compartments of the central nervous system ("CNS"). Approximately 66% of RTs occur in the CNS and are called ATRTs. ATRTs predominantly affect infants and young children, with up to 15% of ATRTs arising in the brain. Incidence of ATRT is between 1.4 and 3.0 per million, and the survival rate is between 10% and 15% depending on the age at diagnosis. Pediatric brain cancer is the second-leading cause of pediatric cancer death with the incidence rate growing at ~2.7% per year in the United States.
Dr. Eric Raabe, M.D., Ph.D., is assistant professor of oncology in the Division of Pediatric Oncology at Johns Hopkins and a co-principal investigator at the Pacific Pediatric Neuro-Oncology Consortium. A physician-scientist, Dr. Raabe has devoted his career to the pursuit of treatment options for the most high-risk pediatric brain cancers, including ATRT where Dr. Raabe uses a unique and highly curated panel of cell lines and xenografts in preclinical studies for drug development and research. These models have had extensive molecular and genomic profiling including biomarker studies to help better understand the ATRT and other related CNS cancers.
Over 90% of cases of ATRT are caused by a mutation which drives a partial or whole loss of chromosome 22, resulting in the inactivation of the SMARCB1 gene (Switch/sucrose nonfermentable [SWI/SNF] related, Matrix-associated, Actin-dependent Regulator of Chromatin, subfamily B1). SMARCB1 is a protein encoding and tumor suppressor gene which drives downstream production of the SMARCB1 protein and other SWI/SNF protein subunits which are thought to act as tumor suppressors. While ATRT is diagnosed with standard immunochemistry staining to detect loss of the respective protein(s), no standard of care currently exists for ATRT and ATRT in the brain is typically unresectable. Treatment options are typically limited to only chemotherapy agents since radiotherapy is not advised in children.
"To support the discovery and development of innovative medicines that may help children diagnosed with rare diseases, the U.S. FDA has created a Rare Pediatric Disease Designation. We believe that the rarity of incidence of ATRT in the U.S and its prevalence in children supports the potential for LP-184 to qualify in the future for a possible grant by the US. FDA for a Rare Pediatric Disease Designation for use of LP-184 for ATRT," continued Mr. Sharma. "Moreover, if we are successful in receiving a Rare Pediatric Disease Designation, we believe LP-184, if it receives ultimate approval, may possibly qualify for the granting by the U.S. FDA of a Rare Pediatric Disease Priority Review Voucher ("PRV"). We believe the award of a PRV would represent a significant value enhancing milestone for Lantern Pharma."
Lantern Pharma plans on continuing to use RADR to potentially uncover and develop other indications in brain and CNS cancers where LP-184 has the potential to show efficacy.
