Assessing the Safety and Effectiveness of Intracoronary Stem Cells in Patients With Refractory Angina
A Phase II Randomised Sham-controlled Trial Assessing the Safety and Efficacy of Intracoronary Administration of Autologous Bone Marrow Cells in Patients With Refractory Angina
Barts & The London NHS Trust
110 participants
Mar 1, 2024
INTERVENTIONAL
Conditions
Summary
REGENERATE-COBRA will examine whether autologous stem cell treatment can improve angina symptoms and quality of life for patients with refractory angina. Patients will be randomised (randomly allocated with a 50:50 chance) to either the 'treatment' or the 'sham' group - they will not know which group they are in. In the 'treatment' group: * Stem cells will be collected from bone marrow in the patient's hip under local anaesthetic (a bone marrow aspiration). * Under local anaesthetic, the stem cells will be infused into the arteries that supply blood to the heart through a small tube inserted either in the wrist or the groin. * The follow-up involves a phone call at 1 month and 12 months and clinic visit at 6 months. In the 'sham' group: * A sham bone marrow aspiration is performed - a 3mm nick in the skin will be made under local anaesthetic. * A sham cell infusion is performed - a small tube is inserted either in the wrist or groin under local anaesthetic. * The follow-up involves a phone call at 1 month and 12 months and clinic visit at 6 months.

Interventions
Bone marrow will be harvested from the posterior superior iliac crest under local anaesthetic, and mononuclear cells will be separated using a Ficoll technique in a certified laboratory. Later that same day, the participant will undergo an intracoronary cell infusion of the mononuclear cells. Participants will be blinded to their treatment arm (they will wear a blindfold and noise cancelling headphones for the bone marrow aspiration and cell infusion).
These participants will have a sham bone marrow aspiration (a 3mm incision in the skin under local anaesthetic) and a sham intracoronary infusion procedure (the insertion of radial or femoral sheath under local anaesthetic). Participants will be blinded to their treatment arm (they will wear a blindfold and noise cancelling headphones for the sham bone marrow aspiration and sham cell infusion).
