On August 7, 2024 Lantern Pharma (NASDAQ: LTRN), a clinical-stage biopharmaceutical company leveraging artificial intelligence (AI) and machine learning to transform the cost, pace, and timeline of oncology drug discovery and development, reported a significant advancement demonstrating the preclinical synergy of LP-184 with checkpoint inhibitors and the ability of LP-184 to resensitize tumors that have become non-responsive to Anti-PD1 therapies (Press release, Lantern Pharma, AUG 7, 2024, View Source [SID1234645514]). The company will be presenting preliminary data from the recent work done in conjunction with Drs. Yong Du and Shiaw-Yih (Phoebus) Lin at MD Anderson at The Immuno-Oncology Summit 2024 in Philadelphia.

The data will be presented in the form of poster entitled, LP-184, a Novel Acylfulvene, Sensitizes Immuno-Refractory Triple Negative Breast Cancers (TNBCs) To Anti-PD1 Therapy by Affecting the Tumor Microenvironment, (assigned Poster # P17). The poster highlights the following key points:
LP-184 seems to potentiate anti-PD1 response in a mouse model of TNBC that is non-hypermutated and resistant to immunotherapy in the absence of LP-184.
LP-184 can potentially transform immunologically "cold" tumors (non-responsive to IO therapies) into "hot" tumors (responsive to IO therapies) by modulating T cell activity in the tumor microenvironment and inducing a replication stress response defect.1
LP-184 seems to reshape the tumor microenvironment (TME) by significantly reducing the amount of M2 macrophages – which are associated with tumor drug resistance, tumor cell proliferation and are involved in helping the tumor cells escape immune cell death2.
LP-184 combined with an anti-PD1 agent elicited a greater anti-tumor response than monotherapies in mouse TNBC tumors that are non-hypermutated and resistant to immune checkpoint inhibitors
LP-184 is being investigated in an ongoing first-in-human Phase 1 trial (NCT05933265) in advanced recurrent solid tumors to establish a maximum tolerated dose and assess its overall safety and suitability in more targeted cancer indications, including TNBC.
Immunotherapy with checkpoint inhibitors (CPI) account for nearly $48 billion in sales annually according to Grand View Research and has profoundly changed the landscape of treatment in oncology since their introduction by providing outstanding durable responses and potential long-term remission in a significant proportion of cancer patients.3 Treatments are now approved for more than thirty cancer indications including melanoma, lung, colon, renal, urothelial, gastric, liver, lymphoma, head and neck but only a minority of patients benefit (10% to 50% depending on the stage and site of the tumor) and often patients will be non-responsive to CPI.
"Our drug-candidate, LP-184 has shown very promising preclinical evidence supporting its role in immuno-oncology to help patients improve response and durability of response to IO therapies. This work in collaboration with MD-Anderson supports our initial AI-driven hypothesis regarding the role of LP-184 to synergize with PD1 and PDL1 drugs and potentially improve the lives of a greater number of cancer patients globally. We look forward to developing combination drug studies and clinical trials with LP-184 and checkpoint inhibitors," said Lantern Chief Scientific Officer, Kishor Bhatia, PhD, FRCP.
The entirety of the data and poster to be presented at The Immuno-Oncology Summit 2024 in Philadelphia will be available on the Lantern website after 6pm Eastern today, August 7th 2024.
