Hamburg, Germany, May 6, 2025 – Topas Therapeutics presented positive clinical proof-of-concept data demonstrating gluten-specific tolerance induction in celiac disease (CeD) patients. Data from a Phase 2a clinical trial evaluating TPM502, the company’s lead candidate, demonstrated a positive safety and tolerability profile, a significant reduction of the inflammatory responses to gluten and long-lasting phenotypic changes to gliadin-specific T cells. In addition, TPM502-treated patients reported a beneficial impact on symptoms post a gluten challenge. Developed using Topas’ proprietary platform, TPM502 consists of nanoparticles coupled with CeD disease-relevant antigens. The study findings were presented at Digestive Disease Week® (DDW) 2025 on Monday, May 5, 2025, in an oral presentation and were selected for the American Gastroenterological Association Presidential Plenary

“The data presented at DDW represent a significant validation of TPM502 as a potential treatment for celiac disease. The observed safety profile, combined with the clear, dose-dependent reduction of IL-2 and IFN-γ release by gluten-specific T cells as well as phenotypic changes in antigen-specific CD4+ T cells, reinforces TPM502’s ability to precisely and durably modulate the underlying autoimmune response to gluten,” stated Knut E. A. Lundin, MD, PhD, Principal Investigator of the Phase 2a study and Professor and Head of Clinical Education at the Institute of Clinical Medicine, University of Oslo.

“By directly addressing the pathogenic T-cell activation central to celiac disease, TPM502 could redefine the treatment paradigm and provide a much-needed therapeutic option for patients who currently have no approved alternatives to a lifelong gluten-free diet. Indeed, the gluten-free diet does not meet the medical needs of many celiac disease patients,” added Cristina de Min, MD, CMO of Topas Therapeutics.  “Our Phase 2a trial data also support the application of our nanoparticle platform for a range of autoimmune disease indications for which tolerance induction could be a transformative therapeutic approach.”

The multi-center, double-blind, randomized, placebo-controlled Phase 2a study evaluated TPM502 in HLA-DQ2.5 positive adults with confirmed CeD on a gluten-free diet (NCT05660109). HLA-DQ2.5 is a very common genetic variant among CeD patients, representing approximately 90% of the total disease population.[1] A total of 38 patients that achieved a predefined IL-2 response to bolus gluten challenge (6 g gluten) were randomized and assigned to placebo or 1 of 4 dose cohorts, receiving 2 intravenous infusions of TPM502 (from 0.72 μmol to 7.2 μmol total peptide dose) on day 1 and day 15. A total of 26 patients received TPM502 and 12 received placebo. The gluten challenge was repeated 7 days after the second administration of TPM502 or placebo. As reported in the DDW presentation, TPM502 demonstrated a favorable safety profile. Treatment-related adverse events (TAEs) were reported in 27 patients, including 8 on placebo, with the majority being Grade 1 or 2 events such as nausea, headache, and vomiting; only a single patient experienced four Grade 3 TAEs.

Importantly, a significant and dose-related reduction of IL-2 and IFN-γ release by gluten-specific T cells was observed after TPM502 treatment at the highest dose, which was maintained throughout the study period of 1 month following the last TPM502 administration. In addition, immunomodulation was demonstrated by post-treatment phenotypic changes in gluten-specific CD4+ T cells consistent with T cell anergy or exhaustion and a significant increase in gluten-specific regulatory CD4+ T cells at the highest TPM502 dose, suggesting the induction of regulatory status in these T cells. Patient-reported outcomes using a Celiac Disease Patient‐Reported Outcome (CeD PRO®) tool, indicated a dose-dependent reduction in gastrointestinal symptoms in TPM502-treated patients compared to placebo, following the post treatment gluten challenge.

“Topas Therapeutics is committed to advancing TPM502 as a much-needed treatment option for celiac disease patients, building on data that represent a breakthrough for this and potentially other immune-mediated diseases,” said Hugo Fry, CEO of Topas Therapeutics. “With this validation of our technology and its ability to modulate immune responses in a precise and durable manner, we look forward to the next clinical steps for TPM502 and our pipeline.”

The abstract was selected for presentation in two sessions at DDW. Further details are listed below and available for registered attendees on the DDW conference website.

Hamburg, Germany, March 17, 2025 – Topas Therapeutics today announced the publication of data highlighting the ability of its proprietary antigen-coupled nanoparticles’ to achieve tolerance induction in relevant autoimmune disease models, under the title “Nanoparticle Platform Preferentially Targeting Liver Sinusoidal Endothelial Cells Induces Tolerance in CD4+ T Cell-Mediated Disease Models” in the journal Frontiers in Immunology. The Topas platform consists of Topas Particles (TPs), that serve as a highly flexible scaffold for coupling with disease-relevant antigens to generate Topas Particle Conjugates (TPCs) that preferentially harness liver sinusoidal endothelial cells (LSECs) to generate antigen-specific tolerance. The publication describes the ability of TPCs to specifically reach LSECs and to generate tolerance in well-established animal disease models of Type 1 Diabetes (T1D) and Multiple Sclerosis (MS). In addition to the proof-of-concept data from the Phase 2a trial evaluating Topas’ lead candidate TPM502 in adults with celiac disease, the preclinical data reported in the publication underscores the broad potential of this innovative platform approach.

In vivo data included in the publication show that intravenous administration of TPCs resulted in predominant uptake by LSECs with negligible uptake by other non-parenchymal liver cells, confirming its cellular targeting specificity. LSECs are lining the liver sinusoids, a position that puts them in direct contact with antigens in the blood. This location, combined with their extraordinary clearance and tolerogenic function, facilitate LSECs’ rapid uptake of nanosized peptide carriers for antigen-specific tolerance induction in various CD4+ T cell-dependent disease models. In a translational mouse model of T1D, a Topas particle mixture comprising five different peptide-coupled TPCs, significantly reduced the frequency of hyperglycemia onsets compared to control, suggesting that even for complex diseases such as T1D, induction of immune tolerance is possible. In a mouse model of multiple sclerosis (MS), administration of TPCs both prior to disease induction and during disease onset, significantly attenuated disease severity and mitigated demyelination within spinal cords as compared to the control, highlighting the TPCs’ ability to induce tolerance prophylactically and therapeutically.

“These published results, coupled with the efficacy data we have established in celiac disease, further support our broad development strategy of advancing TPM502 into a Phase 2b study in celiac disease patients while expanding our pipeline with TPC candidates in highly prevalent autoimmune diseases,” said Cristina de Min, MD, CMO of Topas Therapeutics. “We look forward to presenting the full data analysis of our Phase 2a study during the Digestive Disease Week in San Diego in May, as a further clinical demonstration of what we believe can be transformative approach in promoting immune tolerance.”

“The publication in Frontiers in Immunology underscores the potential of the innovative Topas platform for reinstating antigen-specific tolerance in many autoimmune diseases, while avoiding the complications of broad immunosuppression,” said Hugo Fry, CEO of Topas Therapeutics. “The data pave the way for exploring our TPCs in indications like type 1 diabetes and serves as a foundation to realize the significant potential across autoimmune and immune-mediated diseases.”

Hamburg, Germany, October 15^th, 2024 – Topas Therapeutics today announced positive topline results from its Phase 2a trial evaluating lead candidate, TPM502, in patients with celiac disease. The study data serves as the first clinical proof of concept for Topas’ proprietary nanoparticle platform and its potential to induce targeted, antigen-specific tolerogenic effects.

The international, multi-center, double-blind, randomized, placebo-controlled Phase 2a trial (NCT05660109) was initiated in 2023 to investigate the safety, tolerability and pharmacodynamics of two infusions of TPM502 in adult patients with celiac disease.  Pharmacodynamic parameters were assessed through a gluten challenge after patients received treatment with TPM502 or placebo. Initial analysis showed that antigen-specific markers of tolerance induction exhibited a clear dose-response that reached statistical significance. Further, these antigen-specific effects persisted throughout the study’s follow-up period. TPM502 was safe at all doses investigated. Topas intends to submit the full data and analysis for presentation at an upcoming scientific conference and for publication in a peer-reviewed journal.

“This first look at the TPM502 Phase 2a data is an important milestone for the Topas team and our mission to demonstrate that our platform induces antigen-specific tolerogenic effects. The data generated in this study underscore the potential of this versatile, novel modality in a broad spectrum of autoimmune and immune-mediated diseases,” said Hugo Fry, CEO of Topas Therapeutics. “We believe these results provide a valuable springboard to the next stage of development for Topas and position the company extremely well in the immune-tolerance space.”

Topas’ lead candidate, TPM502, leverages the company’s proprietary platform, a nanotechnology-based modality designed to induce targeted, antigen-specific immune tolerance. TPM502 is comprised of a mixture of nanoparticles that carry the major gluten epitopes for HLA-DQ2.5, present in the majority of celiac disease patients. TPM502 has been developed to establish long-term immune tolerance that will offer significant therapeutic benefit to celiac patients, who currently have no treatment options.

The initiation of the Phase 2a study for TPM502 builds on promising preclinical data and the excellent safety profile demonstrated in the Phase 1 study assessing Topas’ TPM203 in pemphigus vulgaris patients. The company’s next development steps for TPM502 will be based on the full data analysis.

About Celiac Disease

Celiac disease is an autoimmune disorder characterized by an aberrant immune reaction to ingested gluten that results in damage to the small intestine. It affects 1% of the population and manifests through a wide range of digestive as well as non-digestive symptoms. Diagnosed patients are limited to a gluten-free diet, nevertheless, in a third of cases, severe symptoms persist despite gluten avoidance. There is currently no available medical treatment for celiac disease.

“The initiation of the first clinical study with our lead product candidate is an exciting and at the same time value-generating step forward for Topas,” said Timm Jessen, PhD, Chief Executive Officer. “Pemphigus vulgaris is a well characterized disease with extensive knowledge on the most related autoimmune antigen and biomarkers available. It provides a very good setting to demonstrate the successful translation of our Topas Particle Conjugates platform into the clinic. While treatments do exist for this painful condition, there currently is no cure, and we look forward to advancing TPM203 with the goal of helping patients with this debilitating disease.”

The Phase 1 trial is an open-label study designed to evaluate the safety, tolerability, and pharmacokinetics of TPM203, as well as to explore early signs of effectiveness for TPM203 to induce antigen-specific immune tolerance in this patient population. The study has a single-ascending dose phase, followed by a multiple dose phase. The trial is planned to treat 24 patients and will be conducted at approximately seven sites in Germany; the coordinating investigator is Prof. Michael Hertl from the Dept. of Dermatology and Allergology at University Medical Center Marburg.

Topas Particle Conjugates technology platform harnesses the liver’s natural immunology capabilities
Topas’ technology platform harnesses the natural mechanisms of the liver to promote immune tolerance to blood borne antigens. Small peptide-loaded nanoparticles, Topas Particle Conjugates (TPCs), mimic such blood borne antigens and are taken up by liver sinusoidal endothelial cells (LSECs). LSECs present these antigens to T cells under anti-inflammatory conditions conducive to the induction of tolerogenic regulatory T cells (Tregs) and/or by other mechanisms. Tregs are pivotal for immune tolerance, and their in vivo generation serves to re-instate healthy immune balance (homeostasis) and provide a cure for diseases characterized by undesirable or dysregulated inflammatory immune reactions. The fast and active uptake of circulating TPCs by LSECs leads to rapid clearance of the particles from the bloodstream, allows an exact dosing of the antigen residing in the liver and avoids undesired immune reactions. TPCs provide major competitive advantages, including in vivo traceability, dose-ability, biodegradability and scalability along GMP requirements.

About Pemphigus Vulgaris
PV, an orphan disease, is an autoimmune condition involving a painful blistering on the skin and mucous membranes. If extensive, blistering can lead to life-threatening fluid loss, infection, and disfigurement. In this disease, patients have autoantibodies against desmogleins (proteins that play a role in connecting cells), which disrupt the connections between the squamous cells of the epidermis and cause blisters that can easily burst. Treatment consists of immunosuppressive agents; prognosis is variable, but many patients have a higher than normal mortality rate, and there is no cure.

Topas Therapeutics GmbH (Topas), a Hamburg, Germany-based private company, today announced that it has signed a multi-year agreement with Eli Lilly and Company (Lilly) to collaborate in the field of antigen-specific tolerance induction with an initial focus on external antigens thought to induce inflammation and/or autoimmune disease. Topas will be responsible for conducting pre-clinical proof-of-principle studies in collaboration with Lilly to generate drug candidates. Under the terms of the agreement, Lilly has an option for all candidates produced under the collaboration for in-licensing and further development. Topas will receive R&D; funding and participate in the future success of any compounds in-licensed by Lilly. Financial details of the collaboration are not being disclosed.

Topas’ technology platform induces antigen-specific immune tolerance by harnessing the liver’s natural immunology capabilities; peptide-loaded nanoparticles are selectively targeted towards liver sinusoidal endothelial cells (LSECs). LSECs are one of the body’s premier sites to induce tolerance against bloodborne antigens by generating peptide-specific regulatory T cells.

Timm Jessen, CEO of Topas Therapeutics, said: “We are excited to be working with Lilly to generate drug candidates using our proprietary technology. We expect this work to support the value of our approach in inducing tolerance also against external antigens. Additionally, the interest from such an important pharmaceutical company in our technology, we believe, supports the strong commercial potential of our work.”

Thomas F. Bumol, Ph.D., senior vice president of biotechnology and immunology research at Lilly, added: “Lilly is committed to be an innovation leader in immunology. Topas has a very novel approach to immune tolerance induction, which we would like to see successfully applied to certain disease relevant antigens. We look forward to working together with Topas on their unique platform.”
