Lantern Pharma Inc. (NASDAQ: LTRN), a clinical-stage AI-driven precision oncology company leveraging its proprietary RADR^® artificial intelligence (AI) and machine learning (ML) platform to transform the cost, pace, and timeline of oncology drug discovery and development, today announced operational highlights and financial results for the first quarter ended March 31, 2026, and provided an update on its portfolio of AI-driven drug candidates and AI platforms.

The first quarter of 2026 was defined by capital-efficient execution across Lantern’s clinical and AI platform pipelines. The Company advanced multiple clinical-stage programs through meaningful regulatory and scientific milestones, including a successful outcome from an FDA Type C meeting interaction on the Phase 2 HARMONIC™ trial of LP-300 and IND clearance for the first pediatric CNS cancer program of wholly-owned subsidiary Starlight Therapeutics, while reducing research and development spend by 47% year-over-year. In parallel, Lantern moved its proprietary AI infrastructure from internal capability to external commercial product with the launch of withZeta.ai, the first multi-agentic AI co-scientist platform purpose-built for rare and complex cancer drug development. The recent fundraise of up to $9.25 million (which includes the potential future exercise of warrants) further strengthens the Company’s balance sheet and supports continued advancement of both its clinical pipeline and its AI commercialization strategy.

“The first quarter of 2026 demonstrated the operating discipline and capital-efficient execution that we believe is differentiating Lantern from other clinical-stage and AI-driven oncology companies,” said Panna Sharma, President and CEO of Lantern Pharma. “We reduced our R&D spend by 47% year-over-year while simultaneously advancing multiple clinical programs through important regulatory milestones, achieving a successful outcome from our Type C meeting request with the FDA on the HARMONIC™ trial, and clearing the path for Starlight Therapeutics’ first pediatric brain cancer trial. This level of milestone delivery on a tightly disciplined budget reflects exactly what our AI-driven drug development model was designed to do — develop more programs, more quickly, and at a fraction of the historical cost of biopharma R&D.”

In addition to Lantern’s clinical pipeline advancements, the first quarter also marked a pivotal evolution in the commercialization of the Company’s AI assets. With the public launch of withZeta.ai and the continued global expansion of the RADR^® platform through the Company’s initiation of an AI Center of Excellence in India, Lantern is now operating two distinct value-creation engines: a clinical-stage drug development business aimed at advancing therapies across solid tumors, blood cancers, and pediatric brain cancers; and an AI platform business addressing the multi-billion-dollar opportunity in AI-enabled drug discovery and rare cancer research. To accelerate value realization across both engines, the Company has announced a strategic plan to create an independent business entity composed of its withZeta.ai platform assets, intended to access dedicated funding sources and pursue valuation distinct from clinical drug development operations.

“withZeta.ai represents Lantern’s first agentic-based commercial AI product, and we believe it is positioned to capture a meaningful share of what we view as a $20 to $50 billion near-term market opportunity in AI-driven drug development,” continued Mr. Sharma. “Separating our withZeta.ai assets into an independent entity is intended to unlock dedicated funding, attract specialized talent, and allow investors to value each business — clinical drug development and AI platforms — on its own terms. Combined with the recent financing, which extends our operating runway into the first quarter of 2027, Lantern enters the remainder of 2026 with a stronger balance sheet, a sharper commercial focus, and a portfolio of AI-driven oncology drug candidates with an estimated combined annual market potential exceeding $15 billion.”

Clinical Pipeline Developments

Lantern’s AI-driven clinical pipeline encompasses multiple drug candidates across solid tumors, blood cancers, and pediatric oncology, with a combined estimated annual market potential exceeding $15 billion. The portfolio includes a Phase 2 clinical program (LP-300) in NSCLC focused on never-smokers and non-smokers with the EGFR exon 21 L858R mutation; planned Phase 1b/2 trials (LP-184) in precision, biomarker-defined solid tumors; and an ongoing Phase 1 program in hematologic malignancies and adult soft tissue sarcomas (LP-284). Additionally, through wholly-owned subsidiary Starlight Therapeutics, the Company has a planned Phase 1 pediatric CNS cancer trial and a planned Phase 1b trial in adult relapsed glioblastoma (GBM) in combination with spironolactone, both with STAR-001 (LP-184). Each program has been guided by the RADR^® platform’s AI-driven insights. On average, Lantern’s newly developed drug programs have been advanced from initial AI insights to first-in-human clinical trials in 2–3 years and at approximately $1.0–2.5 million per program.

LP-300 HARMONIC™ Trial: Successful Type C Meeting Request Outcome and Path Forward

In May 2026, Lantern received responses from its Type C meeting request to the U.S. Food and Drug Administration to discuss proposed protocol amendments to the Phase 2 HARMONIC™ trial of LP-300 in never-smokers with advanced non-small cell lung cancer (NSCLC) adenocarcinoma. The Company received a successful outcome from the meeting request and no objections from the FDA on key proposed amendments to the study, providing an emergent regulatory path forward for the trial.

• Focused Patient Enrollment: Future HARMONIC™ enrollment will focus on patients with the EGFR exon 21 L858R mutation, a subtype of tyrosine kinase mutations that demonstrates lower sensitivity and inferior treatment outcome to osimertinib based therapy. Preliminary analysis of study data suggests that patients with this mutation may derive greater clinical benefit from the LP-300 triplet regimen.
• Extended Treatment Cycles: The maximum number of LP-300 treatment cycles will be increased from six to eight, supported by historical safety data indicating that up to eight cycles of LP-300 at the current dose level did not alter the established safety profile of the drug.
• Study Design Change: The study will discontinue enrollment into the control arm while migrating into a single arm study and only enroll additional patients with EGFR exon 21 L858R mutation. This change reflects the evolution of the treatment landscape for TKI-refractory NSCLC that has made continued randomization to the control arm increasingly challenging.

The HARMONIC™ trial is ongoing at clinical sites in the United States, Japan, and Taiwan. Targeted enrollment in Japan was completed in July 2025 across five clinical sites, including the National Cancer Center Tokyo, and the trial continues to enroll patients in the U.S., as well as in Taiwan, where more than 50% of lung cancer cases occur in never-smokers. The trial has previously demonstrated encouraging results in its initial safety lead-in cohort, showing an 86% clinical benefit rate and 43% objective response rate among the first seven patients enrolled in the United States, including one patient who achieved a durable complete response in target cancer lesions with survival continuing for nearly two years.

Lantern is actively exploring collaboration and partnering opportunities both globally and regionally to maximize LP-300’s commercial potential in multiple geographies. Additional clinical data updates from the HARMONIC™ trial are expected in the second half of 2026.

Never-smoker NSCLC is increasingly recognized as a distinct disease entity with unique clinical and genomic characteristics, representing a global market opportunity estimated at over $4 billion annually. Currently, there are no therapies specifically approved for never-smoker NSCLC patients.

Starlight Therapeutics: FDA IND Clearance for Pediatric CNS Cancer Trial and Expanded Adult GBM Program

In early 2026, the FDA cleared the Investigational New Drug (IND) application for Starlight Therapeutics’ planned Phase 1 pediatric CNS cancer trial of STAR-001 (LP-184) in Atypical Teratoid Rhabdoid Tumor (ATRT) and other rare pediatric cancers, marking a pivotal regulatory milestone for Lantern’s wholly-owned subsidiary. STAR-001 has received both Rare Pediatric Disease Designation and Orphan Drug Designation from the FDA for ATRT, along with additional designations for hepatoblastoma, rhabdomyosarcoma, and malignant rhabdoid tumors.

These designations provide potential pathways for FDA Priority Review Vouchers (PRVs) upon a potential future approval. PRVs have historically been sold or transferred for significant value, with recent transactions in the range of $100 million to $150 million or more, representing a potentially meaningful source of non-dilutive value for Lantern and its shareholders independent of the commercial potential of the underlying therapy. The Rare Pediatric Disease Designations for ATRT, hepatoblastoma, rhabdomyosarcoma, and malignant rhabdoid tumors each independently qualifies for a potential PRV upon potential FDA approval and meeting other program conditions.

In addition to the pediatric CNS program, Starlight is advancing plans for a Phase 1b trial of STAR-001 in adult patients with relapsed glioblastoma (GBM) in combination with spironolactone. Preclinical studies have demonstrated meaningful synergy between STAR-001 and spironolactone in GBM models, with combination treatment producing enhanced anti-tumor activity relative to either agent alone. The combination leverages Lantern’s RADR^®-driven insights into DNA damage repair vulnerabilities in GBM, and Starlight believes the program has the potential to address a significant unmet need in a cancer indication where median overall survival following recurrence remains under nine months despite decades of clinical research.

Glioblastoma remains one of the most treatment-resistant cancers, with approximately 12,000 new cases diagnosed annually in the United States and a global incidence representing a multi-billion-dollar market opportunity. Lantern and Starlight are exploring partnership and collaboration opportunities to accelerate the development of STAR-001 across both pediatric and adult CNS indications.

withZeta.ai: Commercial Launch & Evolution Towards An Independent Entity

In April 2026, Lantern publicly launched withZeta.ai, the first multi-agentic AI co-scientist platform purpose-built for rare and complex cancer drug development. The launch was marked by a Nasdaq MarketSite debut, a live demonstration at the American Association for Cancer Research (AACR) 2026 Annual Meeting, and a dedicated investor and analyst webinar covering five oncology use cases ranging from biomarker discovery to clinical trial design optimization. Since its introduction, withZeta.ai has been actively used and evaluated by biotech companies, cancer research centers, biopharma consultants, and institutional investors across the United States, Europe, and Asia.

withZeta.ai is designed to accelerate drug development insights, therapeutic strategy generation, cancer trial development, and research workflows across more than 438 rare cancer indications — a category of diseases that collectively represents a massive unmet medical need, but where individual indications have historically been underserved due to small patient populations, sparse and scattered data, and limited commercial incentives. The platform combines multiple specialized AI agents that work collaboratively to analyze genomic data, identify potential therapeutic targets, predict drug-tumor interactions, and generate actionable development strategies, drawing on Lantern’s unique expertise and proprietary data assets in rare and orphan cancer drug development.

Planned Separation into an Independent Business Entity

In connection with the May 2026 financing, Lantern announced a strategic plan to separate withZeta.ai and related personnel into an independent business entity under the leadership of Panna Sharma. The separation is intended to provide withZeta.ai with dedicated funding sources and the opportunity to realize valuation multiples distinct from Lantern’s clinical-stage drug development operations.

This reflects Lantern’s broader strategic evolution toward operating two distinct value-creation engines: 1) a clinical-stage drug development business aimed at advancing therapies across solid tumors, blood cancers, and CNS cancers; and 2) an AI platform business addressing the multi-billion-dollar opportunity in AI-enabled drug discovery and cancer research. Lantern believes that withZeta.ai is positioned at the intersection of two high-growth markets — the global rare disease therapeutics market, and the broader AI-enabled drug discovery and pharmaceutical R&D outsourcing market. Analysts estimate that the AI-enabled outsourcing and platform market for pharmaceutical companies will be in the range of $20 to $30 billion by 2030.

Lantern plans to host a dedicated investor webinar during the first half of June 2026 to provide additional detail on the withZeta.ai platform’s commercial trajectory, the contemplated independent business entity, the strategic rationale for the planned separation, and anticipated next steps. Registration details will be communicated through the Company’s investor relations channels in advance of the webinar.

predictBBB.ai: Evolution into a Molecular Intelligence Web Service Powered by a Large Quantitative Model

During the first quarter of 2026, Lantern completed a major expansion of predictBBB.ai, repositioning the platform from a focused blood-brain barrier permeability prediction tool into a first-of-its-kind molecular intelligence web service powered by a Large Quantitative Model (LQM). The expanded platform extends beyond BBB permeability prediction to a broader set of molecular and structural analyses designed to accelerate small molecule drug design and optimization for CNS and non-CNS indications alike.

The underlying LQM architecture is purpose-built for the prediction of quantitative molecular properties — including permeability, solubility, binding affinity, metabolic stability, and structural similarity — across a wide range of therapeutic chemistry contexts. By moving from a single-property predictor to a multi-property intelligence service, predictBBB.ai is now positioned to serve a broader user base of medicinal chemists, computational scientists, and translational researchers working across oncology, neurology, and other therapeutic areas.

predictBBB.ai continues to demonstrate industry-leading performance benchmarks, holding five of the top eleven positions on the Therapeutic Data Commons Leaderboard for blood-brain barrier permeability prediction, with the lead model achieving 94.1% accuracy. The platform is accessible through a web-based service interface designed for ease of use by both individual researchers and enterprise drug discovery teams.

The repositioning of predictBBB.ai complements Lantern’s broader AI platform strategy alongside the RADR^® platform and withZeta.ai, reinforcing the Company’s position as a creator and innovator of differentiated, oncology- and rare-disease-focused AI infrastructure for global biopharma drug development.
