Lantern Pharma Completes LP-184 Trial, 63 Patients Show Promising Efficacy
Lantern Pharma announced additional details and clinical insights from its completed Phase 1a dose-escalation study of LP-184 as well as highlights from its recent webinar. The clinical trial demonstrated durable disease control in 63 heavily pre-treated patients with advanced solid tumors, many of which had DNA damage repair pathway deficiencies. The clinical trial met all primary endpoints for safety, tolerability, and established a clear recommended phase 2 dose. Building on these Phase 1a results, Lantern is advancing an ambitious precision oncology development strategy featuring multiple biomarker-guided Phase 1b/2 clinical trials in triple-negative breast cancer, glioblastoma multiforme, non-small cell lung cancer and advanced urothelial carcinoma. Overall, 63 heavily pre-treated patients with advanced solid tumors enrolled; trial achieved 54% disease control rate in patients at or above therapeutic dose levels, demonstrating promising activity in DNA damage repair-deficient cancers. Patients with stage 4 squamous lung cancer, thymic carcinoma, and gastrointestinal stromal tumor remain on treatment with 12+ to 23+ months of ongoing clinical benefit and meaningful tumor reductions after failing multiple prior therapies. Lantern's Radr platform identified PTGR1 as a key predictive biomarker; greater than 87% of Phase 1a patients exceeded the bioactivation threshold, with a diagnostic-ready molecular assay enabling patient selection and/or stratification. The Phase 1a study enrolled 63 patients with advanced solid tumors who had received a median of three prior lines of therapy. A 62-year-old male patient with stage 4 squamous NSCLC harboring a BRCA1 alteration, who had failed radiation and durvalumab, began LP-184 treatment in December 2023 and continues on therapy with more than 23 months of clinical benefit and 22% target lesion reduction. A 50-year-old male patient with stage 4 thymic carcinoma with a CHEK2 alteration, who had progressed through four prior lines including pembrolizumab, started LP-184 in November 2023 and remains on treatment with more than 12 months of benefit and 26% target lesion reduction. A 62-year-old female patient with stage 4 gastrointestinal stromal tumor harboring an ATM alteration, who had failed four prior therapies including sunitinib, initiated LP-184 in November 2023 and continues treatment with more than 12 months of benefit and 9% tumor reduction. The trial met all primary endpoints for safety and tolerability and established a clear Recommended Phase 2 Dose with a wide therapeutic window.

Clinical Study Results: Lantern Pharma's Phase 1a dose-escalation study of LP-184 demonstrated promising disease control in patients with advanced solid tumors and DNA damage repair deficiencies, meeting all safety and tolerability endpoints.
Future Plans: The company intends to progress LP-184 into multiple Phase 1b/2 trials following the successful outcomes of the initial study.

Clinical Success of LP-284: LP-284, an AI-driven drug candidate, achieved a complete metabolic response in a patient with aggressive B-cell lymphoma after just two cycles, validating its synthetic lethal mechanism and addressing treatment gaps for patients who have failed CAR-T and bispecific therapies.
Strategic Partnership Potential: The drug's profile presents significant partnership opportunities for biopharmaceutical companies, particularly due to its novel mechanism that overcomes resistance to current therapies and demonstrates preclinical synergy with existing FDA-approved agents like rituximab.
Market Need and Economic Impact: With approximately 200,000 new DLBCL cases diagnosed annually and high post-relapse treatment costs, LP-284's off-the-shelf administration could alleviate both clinical and economic burdens in the post-immunotherapy setting.
Ongoing Development and Future Prospects: Lantern Pharma is advancing LP-284 through a Phase 1 trial while exploring combination therapy opportunities, with plans for further clinical assessments and potential expansion into autoimmune and inflammatory conditions.

Company Presentation: Lantern Pharma Inc. will present at the ThinkEquity Conference on October 30, 2025, at 11:30 a.m. ET in New York, NY, with opportunities for one-on-one meetings available throughout the event.
AI-Driven Drug Development: The company utilizes its proprietary AI platform, RADR®, to enhance oncology drug discovery and development, aiming to address significant challenges in the field and potentially impacting over $15 billion in market potential.
Clinical Programs: Lantern Pharma is advancing multiple clinical programs, including a Phase 2 program and several Phase 1 trials, targeting various cancer types with the goal of providing innovative therapies to patients.
Forward-Looking Statements: The press release includes forward-looking statements regarding the company's future performance and drug development plans, highlighting potential risks and uncertainties that could affect outcomes.

Phase 1a Trial Announcement: Lantern Pharma (LTRN) announced a phase 1a trial to evaluate its drug LP-184 as a potential treatment.
Sign-in Requirement: Users need to sign in to access their portfolio related to the trial or company updates.
