MUNICH, Germany I June 24, 2025 I Thermosome GmbH , a clinical-stage drug development company focused on targeted tumor therapies, today announced new, encouraging data from its ongoing Phase I clinical trial evaluating its lead compound THE001 (DPPG 2 -TSL-DOX) in combination with regional hyperthermia (RHT) for the treatment of soft tissue sarcomas (STS). The Phase I study is assessing the safety, pharmacokinetics (PK), and preliminary efficacy of THE001 + RHT in participants with locally advanced unresectable or metastatic STS, who have exhausted all prior treatment options, including standard doxorubicin (DOX). Despite the early stage of development and a small number of participants, signs of meaningful clinical activity have emerged. Among the heavily pre-treated participants – including patients pre-treated with DOX – the median progression-free survival (PFS) following treatment with THE001 + RHT reached 4.5 months across both dose levels (20 and 40 mg/m²). This exceeds the typical median PFS of 2.7 to 3.5 months observed with first-line DOX therapy in treatment-naïve patients at DOX doses of 75 mg/m 2 , i.e., 2-4x higher than doses of THE001 applied in the Phase I setting. At dose level 2 (40 mg/m²), the mean PFS reached 7.1 months. Two out of three participants in this dose level achieved a partial response (PR) according to Choi criteria and completed the maximum extended treatment phase of 12 cycles (~8.3 months). Notably, one participant whose tumor was initially considered unresectable, could undergo surgical resection at the end of the extended study treatment. This participant showed a tumor shrinkage of -16% in the sum of target lesions, a partial response according to Choi criteria and no vital tumor cells in the resected target lesion. Across dose levels 1 and 2, THE001 + RHT demonstrated a favorable safety profile. There were no dose-limiting toxicities or high-grade treatment-related adverse events that led to treatment discontinuation, underscoring the good tolerability of THE001 in combination with RHT. “These findings not only provide consistent proof of the galenic concept of heat-triggered, largely complete DOX release from THE001, but also demonstrate clinical benefit in a highly challenging patient population,” said Dr. Frank Hermann, Chief Medical Officer of Thermosome. “We are particularly encouraged by the results of one participant who underwent resection after 12 full treatment cycles with THE001 and regional hyperthermia with no vital tumor cells found in the resected target lesion. These results clearly support future exploration in the neoadjuvant setting.” Alexander Eggermont, Professor of Clinical and Translational Immunotherapy, University Medical Center, Utrecht, and a member of Thermosome´s Clinical Advisory Board, commented: “The Phase I data of THE001, a thermosensitive liposomal DOX, and regional hyperthermia in heavily pre-treated DOX-experienced soft tissue sarcoma patients, particularly from dose level 2, are very encouraging. These results demonstrate the clinical potential of this highly innovative approach and provide the necessary foundation for transitioning into Phase II proof-of-concept development. I am excited to support this important work and look forward to advancing this promising therapy, which has the potential to significantly improve outcomes for patients with soft tissue sarcoma, particularly in the neoadjuvant setting.” “It is exciting to see the promising results of THE001 combined with regional hyperthermia, demonstrating strong potential to address the high unmet need for better treatments for soft tissue sarcoma,” added Prof. Shreyaskumar Patel, the Robert R. Herring Distinguished Professor of Medicine and Medical Director of the Sarcoma Center at The University of Texas MD Anderson Cancer Center, Houston Texas, and a member of Thermosome’s Clinical Advisory Board. ”Expansion into Phase II, also including the U.S., would offer a much-needed validation of this new therapeutic strategy for patients with STS. I look forward to supporting the advancement of this innovative treatment option to improve outcomes for patients here in the U.S. and globally on the back of the orphan drug designation granted by the FDA.” Considering supportive feedback from the German Federal Institute for Drugs and Medical Devices (BfArM) on the development of THE001 + RHT in the neoadjuvant setting, the available data from last-line participants are intended to support further development in the neoadjuvant setting. About Thermosome Thermosome is a clinical-stage drug development company focused on targeted tumor therapy combined with immune stimulation for improved cancer therapy. At its core is a novel, proprietary tumor targeting approach that allows for significantly increased local drug concentration and improved tumor penetration to achieve improved clinical treatment efficacy. The first clinical indication for its lead drug candidate THE001 is soft tissue sarcoma, where the Company aims to improve the current standard of care (free doxorubicin). Thermosome’s approach enables targeted tumor treatment independent of specific molecular targets and covers patient populations across all chemo-sensitive tumor subtypes. More information: www.thermosome.com About THE001 Thermosome’s clinical-stage lead drug candidate THE001 is a thermosensitive liposomal formulation of the chemotherapeutic drug doxorubicin (DPPG 2 -TSL-DOX). It has a different mode of action than conventional liposomes. Thermosome’s technology enables intravascular drug release initiated by a mild heat trigger using clinically established hyperthermia devices. This results in up to 15-fold higher local drug concentrations in the tumor and aims to improve clinical treatment efficacy by creating a local boost at the desired site of action. These high local concentrations, which also reach less well perfused areas, are intended to overcome drug resistance. This effect cannot be achieved by administration of conventional doxorubicin due to systemic toxicity. Thermosome intends to further enhance treatment efficacy through an additive immune response induced by regional hyperthermia. THE001 has potential for further development in other anthracycline-sensitive solid tumors, such as breast, bladder, and ovarian cancer. THE001 has been granted Orphan Drug Designation for STS in Europe and the United States. About the Phase I Study The Phase I, open-label, interventional dose-escalation trial enrolling patients with (including DOX-) pre-treated locally advanced unresectable or metastatic STS ( NCT05858710 ) is being conducted at two German clinical sites testing THE001 at various different dose levels in initially up to 6 cycles every 3 weeks with option to extend to up to 12 cycles in participants with at least disease control. Both completed dose level (20 mg/m² and 40 mg/m²) were well tolerated and declared safe by the independent data safety monitoring board (DSMB). Primary endpoints of the study are the safety and tolerability of THE001 and the determination of the maximum tolerated dose. A secondary objective is the evaluation of anti-tumor activity. Initial clinical data were presented at the CTOS 2024 Annual Meeting ( link ). About Soft Tissue Sarcomas (STS) STS is an atypical tumor with a patient population that includes many young patients. Locally advanced STS (LA-STS) are large invasive tumors that are difficult or impossible to resect. Neoadjuvant therapy is used to shrink these tumors preoperatively to allow tumor surgery with curative intent. Free doxorubicin in combination with ifosfamide or dacarbazine has been the gold standard for neoadjuvant therapy of all chemo-sensitive LA-STS for several decades. Guidelines also recommend combining DOX-based therapy with regional hyperthermia. However, with response rates of less than 30%, there is a significant unmet need for improved treatment options. Soft tissue sarcomas occur in more than 50 different subtypes that do not share a common driver mutation, making biologic targeting more difficult than physically controlled targeting with the most active agent.

June 15, 2025 Results from the EPCORE® NHL-2 trial show investigational treatment with epcoritamab in combination with rituximab, ifosfamide, carboplatin, and etoposide (R-ICE) led to an overall response rate (ORR) of 87 percent and a complete response (CR) rate of 65 percent in patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) Data further demonstrates the potential of epcoritamab in combination with salvage chemoimmunotherapy to increase the proportion of patients to qualify for Autologous Stem Cell Transplantation (ASCT) Data was presented during an oral session at the 30th European Hematology Association (EHA) Congress Genmab A/S (Nasdaq: GMAB) today announced new results from the Phase 1b/2 EPCORE® NHL-2 trial Arm 10 (NCT04663347), evaluating epcoritamab, a T-cell engaging bispecific antibody administered subcutaneously, in combination with rituximab, ifosfamide, carboplatin, and etoposide (R-ICE) in adult patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) who are eligible for autologous stem cell transplantation (ASCT). Results demonstrated an overall response rate (ORR) of 87 percent, a complete response (CR) rate of 65 percent and a partial response (PR) of 23 percent. The majority of patients (65 percent) proceeded to ASCT. At six months, an estimated 81 percent of responses were ongoing, 74 percent of patients were progression free, and 100 percent of patients were alive. These results were shared today during an oral presentation at the 30th European Hematology Association (EHA) 2025 Congress. The safety profile of this combination therapy showed cytokine release syndrome (CRS) being low grade and no discontinuations due to treatment-emergent adverse events (TEAEs). The most common TEAEs were neutropenia (74 percent), anemia (68 percent), and thrombocytopenia (68 percent). CRS occurred in 52 percent; all were low grade (1/2) and resolved. One patient had immune effector cell-associated neurotoxicity syndrome (ICANS; grade 1), which resolved. No clinical tumor lysis syndrome was observed. Infections occurred in 18 patients (58 percent); five (16 percent) had serious infections. There were no Grade 5 TEAEs. “These results are particularly encouraging because many of the patients in this study had high-risk disease, having progressed rapidly after initial treatment,” said Raul Cordoba, MD, PhD, Head of the Lymphoma Unit at the Fundacion Jimenez Diaz University Hospital, Madrid, Spain. “This combination therapy of epcoritamab plus rituximab, ifosfamide, carboplatin, and etoposide (R-ICE) offers a potential new treatment option for patients with relapsed/refractory diffuse large B-cell lymphoma, providing high response rates and a bridge to potentially curative autologous stem cell transplantation." Among patients in the study who progressed within 12 months after first-line treatment (n=20), epcoritamab in combination with R-ICE demonstrated an 85 percent ORR and 55 percent CR. Patients in the study who progressed after 12 months from first-line therapy experienced a 91 percent ORR and 82 percent CR. Additionally, patients with one prior line of therapy experienced an 88 percent ORR and 68 percent CR, and patients who were treated with more than one prior line of therapy experienced an 83 percent ORR and 50 percent CR. “The results from this trial highlight the potential of this investigational epcoritamab containing regimen, especially in patients who progress quickly after initial treatment, and reinforce our joint efforts with AbbVie to develop epcoritamab as a core therapy for B-cell lymphomas, especially as we develop epcoritamab in earlier lines of therapy and a broader patient population,” said Dr. Judith Klimovsky, Executive Vice President and Chief Development Officer of Genmab. “Our comprehensive EPCORE clinical trial program is dedicated to advancing epcoritamab as both monotherapy and in combination to address the significant unmet need in relapsed/refractory diffuse large B-cell lymphoma and other hematologic malignancies." Use of epcoritamab + R-ICE in patients with R/R DLBCL eligible for ASCT is not approved and the safety and efficacy of epcoritamab for use as a combination therapy in DLBCL have not been established. DLBCL is the most common type of non-Hodgkin's lymphoma (NHL) worldwide, accounting for approximately 25-30 percent of all NHL cases. In the U.S., there are approximately 25,000 new cases of DLBCL diagnosed each year. DLBCL can arise in lymph nodes as well as in organs outside of the lymphatic system, occurs more commonly in the elderly and is slightly more prevalent in men. DLBCL is a fast-growing type of NHL, a cancer that develops in the lymphatic system and affects B-cell lymphocytes, a type of white blood cell. For many people living with DLBCL, their cancer either relapses, which means it may return after treatment, or becomes refractory, meaning it does not respond to treatment. Although new therapies have become available, treatment management can remain a challenge. EPCORE NHL-2 is a Phase 1b/2 open-label interventional trial to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics/biomarkers, immunogenicity, and preliminary efficacy of epcoritamab as a monotherapy and in combination with other standard of care agents in patients with B-cell non-Hodgkin’s lymphoma (B-NHL). The trial consists of two parts: Part 1 (Dose Escalation) and Part 2 (Dose Expansion). The primary objective of Part 1 is safety, and the primary goal of Part 2 is preliminary efficacy. The primary endpoint was overall response rate (ORR) based on best overall response per Lugano criteria. MRD negativity was assessed as a secondary endpoint. Arm 10 of the EPCORE NHL-2 study enrolled 31 patients with R/R DLBCL, who were eligible for R-ICE and ASCT, and had received ≥1 prior line of treatment. At the time of data cutoff (December 18, 2024), median follow-up was 11 months (range, 6−15). Among the 31 patients treated with epcoritamab 48 mg + R-ICE, 61 percent were Ann Arbor stage III/IV, 42 percent had bulky disease ≥7 cm, 81 percent had one prior LOT (range, 1−3), and 65 percent had progressed within 12 months of first-line treatment. Epcoritamab is an IgG1-bispecific antibody created using Genmab's proprietary DuoBody® technology and administered subcutaneously. Genmab's DuoBody-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response toward target cell types. Epcoritamab is designed to simultaneously bind to CD3 on T cells and CD20 on B cells and induces T-cell-mediated killing of CD20+ cells.i Epcoritamab (approved under the brand name EPKINLY® in the U.S. and Japan, and TEPKINLY® in the EU) has received regulatory approval in certain lymphoma indications in several territories. Where approved, epcoritamab is available as a readily accessible therapy without the need for reducing tumor burden (“debulking”). Epcoritamab is being co-developed by Genmab and AbbVie as part of the companies' oncology collaboration. The companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization. Both companies will pursue additional international regulatory approvals for the investigational R/R FL indication and additional approvals for the R/R DLBCL indication. Genmab and AbbVie continue to evaluate the use of epcoritamab as a monotherapy, and in combination, across lines of therapy in a range of hematologic malignancies. This includes five ongoing Phase 3, open-label, randomized trials including a trial evaluating epcoritamab as a monotherapy in patients with R/R DLBCL compared to investigators choice chemotherapy (NCT04628494), a trial evaluating epcoritamab in combination with R-CHOP in adult patients with newly diagnosed DLBCL (NCT05578976), a trial evaluating epcoritamab in combination with rituximab and lenalidomide (R2) in patients with R/R FL (NCT05409066), a trial evaluating epcoritamab in combination with rituximab and lenalidomide (R2) compared to chemoimmunotherapy in patients with previously untreated FL (NCT06191744), and a trial evaluating epcoritamab in combination with R2 compared to chemotherapy infusion in patients with R/R DLBCL (NCT06508658). The safety and efficacy of epcoritamab has not been established for these investigational uses.
