Background and study aims
Amyloidosis is the name for a group of rare, serious condition in which an abnormal protein called amyloid is produced by the bone marrow (spongy tissue inside some bones where new blood cells are produced). Overtime, this protein builds up in tissues, affecting the way that organs work. There are several types of amyloid proteins, the most common being AL (A is for amyloid, L is for Light Chain). Chemotherapy (an anti-cancer drug treatment) and a stem cell transplant (a procedure where halthy cells, called stem cells are infused into the body to replace damaged or diseased bone marrow) can both be used to treat AL amyloidosis. In a stem cell transplant, special cells which have the ability to turn into different types of cell (stem cells), which are usually taken from that patient, are infused into the body to replace damaged or diseased cells. With a stem cell transplant, patients have very high doses of chemotherapy, (sometimes with whole body radiotherapy) to damage or destroy the abnormal cells in the bone marrow. The stem cells then replace these cells so the body can start making healthy blood cells again. In this study, doctors want to look at using targeted radiotherapy in place of high dose chemotherapy. Targeted radiotherapy means that the radiation is given directly to their bone marrow. This destroys the abnormal cells in the same way as high dose chemotherapy does. They have the radiation from a radiolabelled antibody (anti CD66 radiolabelled with Yttrium 90) which is as a single treatment into their vein. This treatment has been used alongside chemotherapy for people with different types of blood cancer. But this is the first time it is being used for people with amyloidosis. The aim of this study is to see how safe it is to use targeted radiotherapy as part of their stem cell transplant, learn more about the side effects and see how well it works.

Who can participate?
Adults with amyloidosis

What does the study involve?
Participants have stem cells collected using normal procedures before the study starts. As part of the study patients have a visit to the hospital to work out how much radiation they should have. They have a different radiolabelled drug (anti CD66 radiolabelled with Indium-111) to have this test. This is the dosimetry and imaging visit. This must be favourable before any treatment is given. About 1 week later they have their radiation treatment with radiolabelled drug anti CD66 radiolabelled with Yttrium-90. This is the study treatment. They have both the radiolabelled drugs as an injection into a vein. They might be also asked to have a bone marrow biopsy (sample taken) between 1 to 14 days after having the Yttrium-90. After the dose finding test, participants have scans 1, 3 and 4 days afterwards. 7 days before their transplant they go to their transplant centre. Their neutrophils (white blood cells that fight infection) are at their lowest so they are be antibiotics to help prevent an infection. They then have their stem cell transplant as they would normally. Participants see the study doctors 30 days after transplant to have a physical examination, blood tests and a bone marrow test. 100 days after their transplant they see the doctors at the National Amyloidosis Centre and have the same tests repeated.

What are the possible benefits and risks of participating?
There are no direct benefits involved with participating in this study. Most of the treatments and assessments the patients will receive/undergo will be standard of care (i.e. they will receive this anyway and so there are no risks other than those related to the standard procedures used.

Scientific titleA Phase I/IIa Study of Targeted Radiotherapy alone for Stem Cell Transplant Conditioning in Systemic AL Amyloidosis
Study acronymTRALA
Study objectivesThe aim of this study is to assess if targeted radiotherapy used as a sole conditioning treatment prior to autologous stem cell transplantation in patients with Systemic AL Amyloidosis is at least as safe and effective, if not better, than existing treatments for Systemic AL Amyloidosis.
Ethics approval(s)South Central - Hampshire B Research Ethics Committee, 13/11/2015, ref: 15/SC/0565
Health condition(s) or problem(s) studiedSystemic AL-Amyloidosis
InterventionThree treatment levels with step-wise increase of the infused [90Y]-labelled anti-CD66 radiation activity. There will be 3 patients in each cohort (which can be expanded if required due to toxicities seen). A minimum of 12 patients maximum of 18 will be recruited.

All patients will undergo dosimetry using [111In]- CHX A"-DTPA anti-CD66 antibody (drug product).This is a one off dose and administered intravenously. All patients must have favourable dosimetry before they are treated with - CHX A"-DTPA anti-CD66 antibody (drug product)[90Y]. The conditioning treatment [90Y] again is a one off treatment administered intravenously.

There are three treatment levels, representing increasing infused radiation activity levels:
1. 30.0 MBq/kg lean body weight [90Y]-radio-labelled murine anti-CD66.
2. 40.0 MBq/kg lean body weight [90Y]-radio-labelled murine anti-CD66.
3. 45.0 MBq/kg lean body weight [90Y]-radio-labelled murine anti-CD66

After their conditioning treatment patients will undergo a stem cell transplant. They are then seen at day 30 and day 100 post stem cell transplant, after which they have completed the study.

The study would recruit patients with AL-amyloidosis due to undergo autologous stem cell transplantation.
