Resolution Therapeutics Receives MHRA Approval for RTX001 Trial in Decompensated Liver Cirrhosis

Resolution Therapeutics, a spin-off from the University of Edinburgh, has received approval from the UK's MHRA to conduct a clinical trial for its lead candidate, RTX001, in patients with decompensated liver cirrhosis. RTX001 is an engineered autologous macrophage therapy aimed at enhancing anti-fibrotic and anti-inflammatory effects in end-stage liver disease patients. The Phase I/II EMERALD study, scheduled to commence enrollment in Q3 2024, will use clinical events as its primary efficacy endpoint and assess biomarkers like the MELD scale. This trial follows the OPAL study, a natural history study in liver cirrhosis patients, which is generating data to optimize the EMERALD study's control arm.

Resolution Therapeutics' CEO, Dr. Amir Hefni, emphasized the MHRA approval as a significant step towards improving outcomes for patients with inflammatory organ diseases through macrophage cell therapy. The company's research is backed by preclinical data demonstrating the advantages of RTX001 over non-engineered macrophages. Additionally, the University of Edinburgh presented promising data from its MATCH Phase II study at the EASL Congress 2024, further validating the potential of macrophage cell therapy in treating advanced liver cirrhosis.

Key Takeaways

  • Resolution Therapeutics receives MHRA approval for RTX001 trial in decompensated liver cirrhosis.
  • RTX001 is an engineered autologous macrophage therapy targeting anti-fibrotic and anti-inflammatory effects.
  • EMERALD study to measure clinical events and biomarkers like MELD as primary endpoints.
  • Patient enrollment for the Phase I/II EMERALD study expected to start in Q3 2024.
  • Resolution Therapeutics, spun out from Edinburgh University, aims to transform outcomes for inflammatory organ diseases.


Resolution Therapeutics' MHRA approval for RTX001 trial could significantly impact healthcare, particularly for end-stage liver disease patients. The trial's success might reshape treatment paradigms, benefiting patients and healthcare systems by reducing hospitalizations and improving quality of life. Financial markets may react positively, boosting Resolution Therapeutics' stock and attracting further investment in macrophage therapy research. The University of Edinburgh and collaborators could see increased funding and recognition. Conversely, competitors in liver disease treatment might face increased pressure to innovate. Short-term, the trial's initiation will drive industry interest and academic collaborations; long-term, successful outcomes could establish a new standard in organ disease treatment.

Did You Know?

  • Engineered Autologous Macrophage Therapy:
    • Autologous cells are derived from the patient's own body, reducing the risk of immune rejection.
    • Macrophages play a crucial role in the immune system by engulfing and digesting cellular debris, foreign substances, and pathogens.
    • Engineered macrophages involve modifying these cells to enhance their therapeutic effects, such as anti-fibrotic and anti-inflammatory properties, beneficial in treating diseases like liver cirrhosis.
  • MELD Scale (Model for End-stage Liver Disease):
    • The MELD scale assesses the severity of chronic liver disease, predicting mortality in patients with end-stage liver disease or those awaiting liver transplantation.
    • It calculates a score based on several laboratory tests including serum bilirubin, serum creatinine, and the international normalized ratio (INR) for prothrombin time, reflecting liver and kidney function.
  • Phase I/II Clinical Trials:
    • Phase I trials focus on determining the safety profile and metabolization of a new treatment.
    • Phase II trials assess the treatment's efficacy against the disease. Conducting both trials simultaneously allows for efficient data collection on safety and efficacy, expediting the development process while ensuring patient safety and treatment effectiveness.
