National Collaborative Centre for Hepatic Regenerative Medicine (NC-CHRM): Evaluating Mesenchymal Stem-Cell (MSC) Therapy in Non-viral Acute on Chronic Liver Failure (ACLF) Patients - Phase-III Trial

Официальное название

National Collaborative Centre for Hepatic Regenerative Medicine (NC-CHRM): To Study the Safety and Efficacy of Mesenchymal Stem-Cell Therapy in the Management of Non-viral ACLF Patients: Phase-III Clinical Study

Обзор

Liver disease deaths are rising, but transplants remain scarce in India. With over 100,000 needed annually and only \~2,500 performed, non-transplant options are urgently needed. Regenerative therapy, especially mesenchymal stem cells (MSCs), shows promise but lacks validation, particularly for non-viral ACLF. The proposed NC-CHRM aims to develop and validate MSC-based therapy to promote native liver regeneration and offer a safe, effective, transplant-free treatment.

Подробное описание

The incidence of deaths from chronic liver diseases (CLD) and cirrhosis are rapidly increasing globally, including India. Liver transplant is the only curative option. Unfortunately, transplant is often not feasible. There is a need for nearly 100,000 liver transplants every year in India, though, only about 2,500 transplants are being done at present across the country. There is therefore, a huge unmet need of developing non-transplant options for chronic liver disease patients. In this regard emerging science of regenerative therapy holds great promises but therapeutic benefit of these therapies is limited due to lack of clinical validation.

Liver failure is failure of regeneration hence, potentiating native liver repair and regeneration can serve as potential non-transplant approaches. Others and us have shown in experimental studies that mesenchymal stem cells (MSCs) can improve hepatic regeneration. MSC therapy trials in decompensated cirrhosis and viral Acute-on-Chronic Liver Failure (ACLF) in Korea, China and Japan have shown promise but their utility in non-viral ACLF is limited. In the proposed National Collaborative Centre for Hepatic Regenerative Medicine (NC-CHRM) we will use this novel regenerative medicine approaches MSC for management of acute liver failure in non-viral ACLF to develop safe and effective regenerative therapy clinical protocol for transplant free management of liver failure in cirrhosis. Using integrated cellular, molecular and functional analysis we will also establish their mechanism of action and identify biomarker to access therapeutic response.

Вмешательства

• Препарат Umbilical cord Mesenchymal stem cell
  ucMSC 1 million/kg will be given once a week for 4 week . 250 ml normal saline will be infused 30 minutes prior to ucMSCs infusion. The fresh ucMSCs will then be infused through IV canula peripherally over 30 minutes followed by a further 250 ml normal saline over 20-30 minutes.
• Препарат Steroid
  Prednisolone 40 mg once daily for 7 days as inpatients. After that Lille score will be calculated on day 7. Responders (Lille score \< 0.45) will be continued on steroids for a total of 4 weeks, followed by 2 weeks oftapering before stopping the therapy. In patients who were non responsive to steroids (Lille score \> 0.45) at day 7, steroids will be stopped at day 7 and will receive only SMT.
• Другое Standard Medical Treatment
  All patients will receive the standard medical treatment.
