Lantern Pharma Announces Development of Drug Candidate LP-184 for Triple Negative Breast Cancer (TNBC) at the San Antonio Breast Cancer Symposium (SABCS)

  • New preclinical results presented at SABCS demonstrate LP-184 has superior anti-tumor efficacy for TNBC, as compared to current TNBC standard of care agents.
  • LP-184 has therapeutic potential not only for primary TNBCs, but also for brain metastases (mets.) stemming from primary TNBC tumors.
  • Each year in the US, there are approximately 8,000 newly diagnosed TNBC patients with an additional 21,000 relapsed TNBC patients, representing an annual market potential of up to $1.7 billion USD.
  • Expanding LP-184's development indications to include TNBC further increases the long-term, potential value of LP-184 across multiple solid tumors that have unmet or underserved patient needs.

DALLAS--(BUSINESS WIRE)-- Lantern Pharma Inc. (NASDAQ: LTRN), a clinical stage biopharmaceutical company using its proprietary RADR® artificial intelligence ("A.I.") and machine learning (“M.L.”) platform to transform the cost, pace, and timeline of oncology drug discovery and development, today announced that it has expanded development of its drug candidate LP-184 to include Triple Negative Breast Cancer (TNBC), one of the most aggressive and malignant forms of breast cancer. New positive preclinical data on the anti-tumor potency of LP-184 for TNBCs was recently presented at the San Antonio Breast Cancer Symposium (SABCS) 2022.

“As many as 20% of all breast cancers are TNBCs, which are tumors that do not express receptors for Estrogen, Progesterone, or HER2. Therefore, drugs targeted at these receptors are not a therapeutic option for TNBC patients. The prognosis of TNBC patients is considerably worse than HR positive breast cancers, with over 50% of patients relapsing in the first 3 to 5 years and metastatic TNBC patients having a median overall survival of less than a year. Due to the poor prognosis and high relapse rate of TNBC, it is imperative to develop new and effective drug candidates for these patients.” stated Kishor Bhatia, Ph.D., Lantern’s Chief Scientific Officer.

The SABCS poster highlights new preclinical results demonstrating LP-184’s potent in vitro and in vivo anti-tumor efficacy across a broad range of breast cancer models, including TNBC models that are resistant to Olaparib, a PARP inhibitor (PARPi) and a current standard of care (SOC) agent for TNBC. LP-184 had low nanomolar potency (average IC50 of 297nM) when tested across a panel of 4 TNBC breast cancer cell lines. Considering LP-184’s in vitro anti-tumor activity for TNBCs, LP-184 was additionally tested in 10 patient derived xenograft (PDX) mouse models of TNBCs, 7 of which were resistant to Olaparib. In all 10 TNBC PDX models, LP-184 treatment led to complete and durable tumor regression of 107-141%.

In addition to LP-184’s preclinical anti-tumor efficacy for primary TNBC tumors, LP-184 may also have added therapeutic potential to treat brain metastases (brain mets.) from TNBCs, which are found in ~14% of TNBC patients at their initial diagnosis. LP-184 was previously shown to have anti-tumor activity in brain mets. cell lines derived from breast, lung and skin cancers, and was additionally shown to have up to 6X more in vitro anti-tumor activity in comparison to multiple brain mets. SOC agents.

“Patients with primary and secondary TNBCs are in urgent need of new and effective therapies. The combined anti-tumor potency of LP-184 in PARPi resistant TNBC PDXs and LP-184’s distinct PARP independent mechanisms, strongly support the potential of LP-184 to be added to the treatment armamentarium for TNBC patients” continued Dr. Bhatia.

About LP-184:

LP-184 is a small molecule drug candidate with a synthetically lethal mechanism of action (MoA) that preferentially damages DNA in cancer cells that harbor mutations in DNA damage repair (DDR) genes and that overexpress the enzyme PTGR1. Lantern is developing LP-184 for genetically defined solid tumors including TNBC, pancreatic, and bladder, as well as several central nervous system (CNS) tumors including glioblastoma, brain mets., and atypical teratoid rhabdoid tumors (ATRT).

LP-184 has been granted Orphan Drug Designation by the FDA for the treatment of pancreatic cancer, malignant gliomas, and ATRT and was also granted a Rare Pediatric Disease Designation for ATRT. These designations and continued positive preclinical data will help to accelerate LP-184 towards a targeted IND submission in Q1 2023 and first in human Phase 1 clinical trials anticipated to commence in Q2 2023.
