The Phase 1 clinical trial (NCT07259213) is designed to study the safety, tolerability, whole-body distribution, and preliminary clinical activity of RAD 402 in patients with advanced prostate cancer. The dose escalation Phase 1 study is designed to determine the Maximum Tolerated Dose (MTD) and/or recommended phase 2 dose (RP2D) for expansion.

"Dosing the first patient in our Phase 1 study of RAD 402 marks an important step forward for Radiopharm and for patients with advanced prostate cancer," said Riccardo Canevari, CEO and Managing Director of Radiopharm Theranostics. "RAD 402 is a differentiated, first-in-class, next-generation radiotherapeutic designed to selectively target KLK3-expressing tumors while minimizing off-target exposure. With preclinical data demonstrating strong tumor uptake and minimal bone or marrow involvement, we are optimistic about its potential clinical profile. Advancing this program into the clinic reflects our continued commitment to delivering meaningful data across our portfolio this year. I like to take the opportunity to thank our partners, TerThera and Cyclotek, for the great support in supplying Tb161, radiolabelling, and distributing RAD 402."

About RAD 402
RAD 402 (NCT07259213) is an anti-KLK3 monoclonal antibody radiolabelled with the radionuclide 161Tb that is being evaluated in a Phase 1/2a clinical trial for the treatment of prostate cancer. Prostate Specific Antigen (PSA) is a widely used biomarker to detect prostate cancer and is encoded by the KLK3 gene. KLK3 is highly expressed in prostate cancer cells along with most adenocarcinomas of the prostate including their metastases and has limited expression in sites outside of the prostrate. Preclinical proof-of-concept biodistribution studies of RAD 402 in mouse xenografts showed strong tumor targeting, limited bone and marrow uptake, and a hepatic excretion profile consistent with expectations for a monoclonal antibody.

"We are extremely excited about the continued progress at Calidi," said Eric Poma, PhD, CEO of Calidi Biotherapeutics. "We continue to advance CLD-401, the first lead from our RedTail platform, towards the clinic and have built a world-class scientific advisory board to aid those efforts. We have also expanded what the RedTail platform can do with our new approach of in situ T-cell engagers."

Fourth Quarter 2025 and Recent Corporate Developments

Partnered with Avance Clinical, a full-service contract research organization (CRO) with a proven track record and experience in obtaining regulatory approval and clinical trial initiation in Australia. The partnership is focused on rapidly initiating a first-in-human clinical trial for CLD-401 in Australia. CLD-401, the Company’s lead asset, is a systemically delivered oncolytic virus that replicates only in tumor cells. CLD-401 induces high concentrations of IL-15 superagonist (IL15 SA) expression in the tumor microenvironment while limiting peripheral exposure.

In parallel, Calidi is pursuing an IND filing with the FDA by the end of 2026. Calidi has interacted with the FDA around the Company’s manufacturing and analytical approaches through its Type D meeting request process. The feedback it has received from the agency supports the use of this process for the clinical development of CLD-401.

Partnered with Matica Bio, a leading CDMO in the field of oncolytic virus manufacturing, for the GMP manufacturing of CLD-401. Matica has successfully executed multiple oncolytic virus programs at its state-of-the-art, purpose-built GMP facility in College Station, Texas. That facility was designed specifically to support complex viral vector modalities like CLD-401.

Presented data demonstrating the expression of an in situ T-cell engagers (TCEs) for solid tumors and the simultaneous expression of a T-cell activating agent (e.g., IL-15 SA) through its systemically delivered RedTail platform at the AACR (Free AACR Whitepaper) Immuno-Oncology (AACR-IO) conference. High expression of in situ TCE coincident with expression of a T-cell activator in the TME may overcome the traditional limitations of TCEs in solid tumor.

Raised $6.0 million in gross proceeds from an underwritten public offering with new and existing investors in Q1-2026 and $0.5 million in gross proceeds from the sale of stock under our ATM in Q4-2025, strengthening the balance sheet and extending Calidi’s cash runway.

On March 27, 2026 Lantern Pharma Inc. (NASDAQ: LTRN) and its CNS-oncology focused wholly owned subsidiary Starlight Therapeutics reported that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for STAR-001 in a planned Phase 1 pediatric clinical trial (IND No. 179145).

STAR-001 is a precision oncology compound whose CNS and pediatric CNS indications were initially identified using Lantern’s proprietary RADR AI platform. The planned trial will evaluate STAR-001 as a single agent and in combination with spironolactone in pediatric patients with relapsed or refractory central nervous system (CNS) malignancies.

The trial is planned to be conducted in collaboration with POETIC — the Pediatric Oncology Experimental Therapeutics Investigators’ Consortium — a multicenter network of 14 leading academic children’s cancer centers across the United States, Canada, and Israel. The study protocol, as reviewed and cleared by the FDA, is titled:

"A PHASE 1, MULTICENTER, OPEN-LABEL, DOSE ESCALATION STUDY OF STAR-001 (LP-184) AS A SINGLE AGENT AND IN COMBINATION WITH SPIRONOLACTONE IN PEDIATRIC PATIENTS WITH RELAPSED OR REFRACTORY CENTRAL NERVOUS SYSTEM MALIGNANCIES."

ADDRESSING A CRITICAL UNMET NEED IN PEDIATRIC NEURO-ONCOLOGY

Pediatric CNS tumors represent one of the most devastating and treatment-resistant categories of childhood cancer. In the United States, an estimated 4,975 new cases of primary brain tumors will be diagnosed in children and adolescents in 2026 alone — making brain tumors the leading cause of cancer-related death among children and adolescents ages 0 to 19. The burden extends far beyond U.S. borders: globally, approximately 47,600 new pediatric CNS tumor cases are diagnosed each year, resulting in an estimated 23,500 deaths annually. Across Europe, the disease is similarly pervasive, with wide disparities in survival outcomes for children facing high-grade or relapsed cancers.

Despite significant advances in molecular profiling and surgical technique over the past two decades, survival outcomes for children with relapsed or refractory high-grade CNS tumors have improved only marginally. For certain diagnoses, the prognosis remains catastrophic. Diffuse Intrinsic Pontine Glioma (DIPG), for instance, carries a median survival of less than 12 months from diagnosis with no approved curative option. For children with relapsed ATRT, GBM, medulloblastoma, and ependymoma, current therapeutic options are equally limited and often associated with severe long-term toxicity.

The trial design provides for STAR-001 (LP-184) to be evaluated across a range of these aggressive pediatric CNS malignancies, including:

Atypical Teratoid/Rhabdoid Tumor (ATRT) — for which Lantern Pharma holds FDA Rare Pediatric Disease Designation
Diffuse Intrinsic Pontine Glioma (DIPG) — a brainstem tumor with virtually no long-term survivors under current standard of care
Glioblastoma (GBM)
Medulloblastoma
Ependymoma
"This IND clearance is a defining milestone for Starlight Therapeutics and a meaningful step forward for pediatric neuro-oncology. For children with relapsed or refractory CNS tumors, the options are desperately limited — and the science behind this planned trial was built to change that. CNS and pediatric CNS cancers were initially identified as priority indications by our team in support from our RADR AI platform, and that same analysis led us to ERCC3, a DNA repair enzyme that high-grade CNS tumors rely on to survive. Our modeling, analysis and subsequent in-vivo and animal studies showed that spironolactone could dismantle that pathway by degrading ERCC3 before STAR-001 even enters the cancer cell. In ATRT models, the combination extended median survival by 181% compared to the control. We believe this represents a genuinely new way to attack these brain cancers, and we are proud to be advancing it through a network of some of the world’s most respected pediatric oncology centers."
— Panna Sharma, CEO & President, Lantern Pharma Inc.; Founder & Chairman, Starlight Therapeutics

NOVEL BIOLOGY: TARGETING ERCC3 TO AMPLIFY DNA DAMAGE — A FIRST-IN-CLASS COMBINATION STRATEGY

A scientifically distinctive and potentially first-in-class feature of the planned trial is a dedicated combination cohort evaluating STAR-001 alongside spironolactone — exploiting a biological vulnerability in CNS tumor cells that Lantern’s RADR AI platform, helped in part to identify as a novel approach to creating synthetic lethality in these brain tumors.

STAR-001 operates through a precision bioactivation mechanism: selectively converted into a potent DNA-crosslinking agent within tumor cells that overexpress PTGR1 (Prostaglandin Reductase 1), it induces DNA double-strand breaks that are lethal to the cancer cell — if left unrepaired. By degrading ERCC3, spironolactone removes that option.

Lantern’s RADR AI platform identified ERCC3 (Excision Repair Cross-Complementation Group 3) — a key helicase in the nucleotide excision repair (NER) pathway — as a central repair mechanism that could be exploited in high-grade pediatric CNS malignancies including ATRT, medulloblastoma, and diffuse midline glioma, compared to low-grade gliomas. Spironolactone — a brain-penetrant, orally administered agent with a long safety record in pediatric patients — degrades ERCC3 through targeted proteasomal degradation, reducing ERCC3 protein levels by at least 50% across tumor models and confirming direct target engagement. With this repair pathway dismantled, STAR-001-induced DNA damage accumulates unrepaired, driving dramatically enhanced tumor cell death based on preclinical observations. In ATRT orthotopic xenograft models, the combination extended median survival from 27 to 76 days — a 181% improvement over control (p = 0.0018) — with comparable results across medulloblastoma and DMG models showing up to a 3- to 5-fold increase in apoptotic cells versus monotherapy (p < 0.0001).

This two-pronged strategy — AI-guided identification of a DNA repair vulnerability, precision bioactivation of a DNA-damaging agent, and pharmacological elimination of the tumor cell’s repair escape route — represents a mechanistically coherent and potentially transformative approach to pediatric CNS cancers where conventional chemotherapy has reached its limits.

"High-grade pediatric brain tumors represent a significant unmet medical need, with few effective options for children whose disease has relapsed or become refractory to standard therapy. STAR-001 is a novel, precision brain-penetrant alkylator, bioactivated by PTGR1, that has demonstrated meaningful activity across multiple malignant pediatric brain tumor types in preclinical models. In collaboration with the POETIC consortium, we have developed a Phase 1 pediatric protocol — reviewed and cleared by the FDA — to assess the safety, tolerability, and preliminary activity of STAR-001, both as a single agent and in combination with spironolactone, in children with recurrent malignant brain tumors. We look forward to initiating this planned trial and to the possibility of delivering a new therapeutic option to children who need it most."
— Marc Chamberlain, M.D., Chief Medical Officer, Starlight Therapeutics

MULTICENTER PEDIATRIC CLINICAL TRIAL DESIGN

The planned trial will be conducted across approximately 15 leading academic pediatric oncology centers in collaboration with POETIC (Pediatric Oncology Experimental Therapeutics Investigators’ Consortium), a multicenter network of 14 institutions — including MD Anderson Cancer Center, Memorial Sloan Kettering Cancer Center, and Lucile Packard Children’s Hospital at Stanford — spanning the United States, Canada, and Israel. The planned trial is subject to obtaining additional funding and it is designed to enroll approximately 18 to 42 pediatric patients aged 1 to 17 years. POETIC’s established clinical infrastructure provides Starlight with the reach to enroll a geographically and demographically diverse patient population across North America and internationally.

ABOUT STAR-001 (LP-184)

STAR-001 is Starlight Therapeutics’ CNS oncology compound, co-developed with Lantern Pharma as LP-184. CNS and pediatric CNS cancers were initially identified as priority indications for STAR-001 through Lantern’s proprietary RADR AI platform, which analyzed genomic and molecular data across tumor types to pinpoint the PTGR1 overexpression signature that makes these malignancies particularly susceptible to STAR-001’s mechanism of action. STAR-001 is a precision acylfulvene-based agent engineered to exploit elevated PTGR1 (Prostaglandin Reductase 1) expression in tumor cells. Laboratory observations have demonstrated that PTGR1-mediated bioactivation selectively converts STAR-001 into a highly reactive DNA-crosslinking species within cancer cells, while normal tissues with lower PTGR1 activity are largely spared. LP-184/STAR-001 has received multiple FDA orphan and rare pediatric disease designations and has demonstrated encouraging activity in early-stage clinical and preclinical studies. In pediatric CNS cancers — where PTGR1 overexpression has been identified across ATRT, GBM, DIPG, medulloblastoma, and ependymoma — we believe STAR-001 represents a scientifically grounded precision approach to a historically intractable disease.

About Ivonescimab

Ivonescimab, known as SMT112 in Summit’s license territories, North America, South America, Europe, the Middle East, Africa, and Japan, and as AK112 outside of Summit’s license territories, is a novel, potential first-in-class investigational bispecific antibody combining the effects of immunotherapy via a blockade of PD-1 with the anti-angiogenesis effects associated with blocking VEGF into a single molecule. By design, ivonescimab displays unique cooperative binding to each of its intended targets with multifold higher affinity to PD-1 when in the presence of VEGF.

This is intended to differentiate ivonescimab as there is potentially higher expression (presence) of both PD-1 and VEGF in tumor tissue and the tumor microenvironment (TME) as compared to normal tissue in the body. We believe ivonescimab’s specifically engineered tetravalent structure (four binding sites) enables higher avidity (accumulated strength of multiple binding interactions) in the TME (Zhong, et al, iScience, 2025). This tetravalent structure, the intentional novel design of the molecule, and bringing these two targets into a single bispecific antibody with cooperative binding qualities have the potential to direct ivonescimab to the tumor tissue versus healthy tissue. The intent of this design, together with a half-life of 6 to 7 days after the first dose (Zhong, et al, iScience, 2025) increasing to approximately 10 days at steady state dosing, is to improve upon previously established efficacy thresholds, side effects, and safety profiles associated with prior approved drugs to these targets.

Ivonescimab was engineered by Akeso Inc. (HKEX Code: 9926.HK) and is currently utilized in multiple Phase III clinical trials. Over 4,000 patients have been treated with ivonescimab in clinical studies globally, and over 60,000 patients when considering those treated in a commercial setting in China, as noted by Akeso.

There are currently 15 Phase III clinical studies that are either announced, ongoing, or have been completed studying ivonescimab, four of which are Summit-sponsored global studies, one of which is a multiregional study sponsored by a cooperative group, and ten of which are being or have been conducted in China by Akeso. Summit began its clinical development of ivonescimab in NSCLC, commencing enrollment in 2023 in two multiregional Phase III clinical trials, HARMONi and HARMONi-3. In 2025, the Company began enrolling patients in HARMONi-7. Summit expanded its Phase III clinical development program into CRC in the fourth quarter of 2025 by initiating enrollment in HARMONi-GI3.

HARMONi is a Phase III clinical trial which intends to evaluate ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who were previously treated with a 3rd generation EGFR TKI (e.g., osimertinib). Detailed results of the study were provided in September 2025, and a Biologics License Application (BLA) was submitted to the United States Food and Drug Administration (FDA) for marketing authorization, which the FDA accepted for filing in January 2026; the goal Prescription Drug User Fee Act (PDUFA) date is November 14, 2026.

HARMONi-3 is a Phase III clinical trial, which is intended to evaluate ivonescimab combined with chemotherapy compared to pembrolizumab combined with chemotherapy in patients with first-line metastatic, squamous or non-squamous NSCLC, irrespective of PD-L1 expression.

HARMONi-7 is a Phase III clinical trial which is intended to evaluate ivonescimab monotherapy compared to pembrolizumab monotherapy in patients with first-line metastatic NSCLC whose tumors have high PD-L1 expression.

HARMONi-GI3 is a Phase III clinical trial evaluating ivonescimab in combination with chemotherapy compared with bevacizumab plus chemotherapy in patients with first-line unresectable metastatic CRC.

Also including Summit’s license territories, a Phase III study is planned to be conducted by GORTEC, a cooperative group dedicated to Head and Neck Oncology, in recurrent / metastatic head and neck squamous cell carcinoma (r/m HNSCC). ILLUMINE is a three-arm Phase III clinical trial which is intended to evaluate ivonescimab monotherapy, as well as ivonescimab in combination with ligufalimab, Akeso’s proprietary anti-CD47 monoclonal antibody, compared to monotherapy pembrolizumab in patients with PD-L1 positive r/m HNSCC.

In addition, Akeso has recently had positive read-outs in three single-region (China), randomized Phase III clinical trials, HARMONi-A, HARMONi-2, and HARMONi-6, for ivonescimab in NSCLC, including a statistically significant overall survival benefit in HARMONi-A with a manageable safety profile in each study.

HARMONi-A was a Phase III clinical trial which evaluated ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with an EGFR TKI.

HARMONi-2 is a Phase III clinical trial evaluating monotherapy ivonescimab against monotherapy pembrolizumab in patients with locally advanced or metastatic NSCLC whose tumors have positive PD-L1 expression.

HARMONi-6 is a Phase III clinical trial evaluating ivonescimab in combination with platinum-based chemotherapy compared with tislelizumab, an anti-PD-1 antibody, in combination with platinum-based chemotherapy in patients with locally advanced or metastatic squamous NSCLC, irrespective of PD-L1 expression.

Akeso is actively conducting multiple Phase III clinical studies in settings outside of NSCLC, including biliary-tract cancer, triple-negative breast cancer, head and neck squamous cell carcinoma, small cell lung cancer, colorectal cancer, and pancreatic cancer.

Ivonescimab is an investigational therapy that is not approved by any regulatory authority in Summit’s license territories, including the United States and Europe. Ivonescimab was initially approved for marketing authorization in China in May 2024. Ivonescimab was granted Fast Track designation by the US FDA for the HARMONi clinical trial setting.
