What HepaRegeniX does

HepaRegeniX GmbH is a clinical-stage biotechnology company headquartered in Tübingen, Germany, developing first-in-class orally bioavailable small molecule inhibitors of MKK4 (Mitogen-Activated Protein Kinase Kinase 4) to harness the liver's innate regenerative capacity. The company's lead candidate, HRX-215 (also known as darizmetinib), is designed to selectively inhibit MKK4 to accelerate hepatocyte regeneration, with the goal of preventing post-hepatectomy liver failure in patients undergoing liver resection (initially for colorectal cancer liver metastases), enabling extended resections for otherwise inoperable patients, and supporting living donor liver transplantation with smaller grafts. A second program, HRX-233, is being developed as a combination therapy for KRAS-driven cancers to overcome resistance to KRAS inhibitors. The MKK4 target was originally discovered by scientific co-founder Prof. Lars Zender at University Hospital Tübingen and has been validated in two Cell journal publications and a PNAS publication.

The company was founded in 2017 and is backed by a syndicate of European life science venture investors including Vesalius Biocapital IV, Wellington Partners, Novo Holdings, Boehringer Ingelheim Venture Fund, Coparion, High-Tech Gründerfonds, and Ascenion GmbH, with cumulative disclosed funding of approximately €36.5 million across a 2020 Series B and a 2024–2025 Series C. HRX-215 completed a Phase I trial in 48 healthy volunteers in 2022 with no drug-related adverse events, and a Phase Ib minor resection study at Mayo Clinic was completed in February 2026 with DSMB-confirmed favorable safety, supporting advancement to a Phase IIa major resection cohort in 85 patients across the U.S., Europe, and Israel by end of 2026. The company holds a 11–50 employee headcount, has no commercial products, and is led by CEO Elias Papatheodorou (formerly Chair, prior CEO of Genkyotex), COO and co-founder Dr. Wolfgang Albrecht, and CMO Dr. Linda Greenbaum (former Novartis executive director and UPenn hepatologist), under Chair Dr. Martin Bonde.

HepaRegeniX's business model is presently pre-revenue, with future revenue contemplated through either direct commercialization of approved therapeutics (distributed via hospital and specialty pharmacy channels) or out-licensing of regional development and commercialization rights to larger pharmaceutical partners. The go-to-market pathway proceeds through standard regulatory approval and pharmaceutical distribution once clinical milestones are achieved. Until then, the company is funded by equity capital deployed against clinical trial execution and platform expansion across hepatology and oncology indications.

Core offering

HepaRegeniX is a clinical-stage biotech developing first-in-class, orally administered small molecule inhibitors of MKK4 to accelerate and enhance liver regeneration. The lead candidate HRX-215 (darizmetinib) targets post-hepatectomy liver failure and liver transplantation applications, while HRX-233 is being developed as combination therapy for KRAS-driven cancers. Products are intended for hospital-based prescription following regulatory approval.

Product overview

HepaRegeniX is a clinical-stage biotech company developing novel small molecule therapeutics based on MKK4 inhibition. The company's lead product HRX-215 (darizmetinib) is a first-in-class oral small molecule MKK4 inhibitor designed to unlock liver regeneration. The company is also developing HRX-233 for KRAS-driven cancer combination therapy. The therapeutic approach harnesses the liver's inherent regenerative capacity by inhibiting MKK4, a master regulator of liver regeneration.
