Modus Therapeutics AB

Stockholm, December 9, 2024 - Modus Therapeutics Holding AB (“Modus”) today announced that the first dose has been administered in the company’s Phase II clinical study evaluating the drug candidate sevuparin for the treatment of chronic kidney disease (CKD) with associated anemia. The study is being conducted at the Centro Ricerche Cliniche di Verona, Italy. This milestone builds in part upon promising preclinical and clinical data recently published in the scientific journal HemaSphere. The article highlights sevuparin’s ability to significantly reduce hepcidin levels—a key regulator of iron metabolism and a crucial contributor to the development of CKD-related anemia—further reinforcing the scientific foundation for the study. Study Design and Objectives The Phase IIa study consists of two parts: • Part 1: Evaluates the safety and determines dose levels of sevuparin through single-dose administration in patients with varying degrees of kidney impairment, alongside a small reference group of healthy volunteers. • Part 2: Focuses on the effects of repeated dosing and clinical outcomes, including hemoglobin levels, kidney function, hepcidin levels, and other biomarkers in patients with advanced CKD and anemia. The study is expected to enroll a total of 50–60 patients, with the completion of Part 1 planned for the first half of 2025. Scientific Background Research has demonstrated that elevated hepcidin levels contribute to iron dysregulation in CKD and chronic inflammation, exacerbating the anemia that occurs in these conditions. In the HemaSphere article, sevuparin was shown to significantly reduce hepcidin levels in both preclinical models and healthy volunteers, achieving reductions of up to 72% at the highest dose. Furthermore, in a preclinical disease model for CKD with anemia presented by Modus at the conference ASH 2023, sevuparin was found to lower hepcidin, treat anemia symptoms and ameliorate the kidney status in mice with CKD. These results, combined with its favorable safety profile, support sevuparin’s potential as an innovative treatment option for patients with limited alternatives today. Comment from CEO Johan Öhd “The initiation of this Phase II study marks an important milestone for Modus Therapeutics and our development of sevuparin as a potential new treatment for patients with CKD-related anemia. We are excited by the scientific progress supporting our clinical strategy and look forward to sharing new data as the study progresses.” For more information on Modus Therapeutics, please contact: John Öhd, CEO, Modus Therapeutics Phone: +46 (0) 70 766 80 97 Email: john.ohd@modustx.com This information is information that Modus Therapeutics Holding AB is obliged to make public pursuant to the EU Market Abuse Regulation.

There is a great need for new treatments that can effectively treat these conditions. Modus’ ambition is to create a paradigm shift in the care of these diseases, where sevuparin could provide therapeutic benefits. Modus Therapeutics is listed on the Nasdaq First North Growth market (“MODTX”). More information is available at www.modustx.com. Sevuparin is a clinical stage, innovative proprietary polysaccharide drug with a multimodal mechanism of action, including immunomodulating, anti-adhesive and anti-aggregate effects. Sevuparin is a heparinoid with markedly attenuated anti-coagulation features that allows severalfold higher doses to be given, compared to regular heparinoids, without the associated risk for bleeding side-effects. Two routes of administration of sevuparin are currently being tested – an IV formulation for in-patient administration and a subcutaneous formulation that allows ambulatory and home care administration.

STOCKHOLM, SWEDEN – November 18, 2024: Modus Therapeutics Holding AB ("Modus") announces that it has received approval from the relevant authorities in Italy for its planned Phase IIa clinical trial with sevuparin. As previously communicated, the planned Phase IIa study will be conducted in two parts. Part 1 aims to establish dosage levels and safety of sevuparin through single doses in 25-30 patients with varying degrees of kidney failure. Part 1 will also include a small reference group of healthy volunteers and may also provide an opportunity to assess early effects on hepcidin in a relevant patient population. Part 2, the so-called "proof of concept" segment, will evaluate the effects of repeated dosing of sevuparin based on the dose levels established in Part I, focusing on endpoints related to anemia, hepcidin, kidney status, and relevant biomarkers in patients with more severe chronic kidney disease and anemia. It is expected to recruit 25-30 patients, bringing the total study enrollment to 50-60 patients. The approval is in line with Modus’ target to execute Part I of the study during the first half of 2025.
