Clinical trials

                                      Welcome to the Amyloidosis Clinical Trials page!

 

This page is designed to be easy to understand for both patients and clinicians alike.

Clinical trials are subdivided into major amyloidosis types: ATTR, AL and Other.

Please SCROLL DOWN for full details.

Clinical trials are listed here once the first health service in Australia has fully opened the trial for patient enrollment.

Once a trial has been listed as being open (or “activated“) at one site, other sites in Australia selected to participate will also be listed, even thought they may not yet be fully open (“pending“).

Please note : Listing a clinical trial on this website does not necessarily equate as endorsement of the trial by the Australian Amyloidosis Network. Any patient interested in a trial should discuss the pros and cons of the studies with their treating practitioner.

For each trial, a description of the trial, including key inclusion and exclusion criteria, and local contacts are provided.

The trial status at each site will be indicated by a symbol.
The key is as follows:

Systemic Light Chain Amyloidosis (AL) trials

Newly diagnosed:

The “CAEL-101” monoclonal antibody trials for newly diagnosed AL Amyloidosis with cardiac involvement are now open in Australia!

All four AAN services, as well as the Royal Adelaide Hospital, are now recruiting patients to these studies!

CAEL101-301: A Phase 3, Double-Blind, Multicenter Study to Evaluate the Efficacy and Safety of CAEL-101 and Plasma Cell Dyscrasia Treatment Versus Placebo and Plasma Cell Dyscrasia Treatment in Plasma Cell Dyscrasia Treatment-Naïve Patients with Mayo Stage IIIb AL Amyloidosis

CAEL101-302: A Phase 3, Double-Blind, Multicenter Study to Evaluate the Efficacy and Safety of CAEL-101 and Plasma Cell Dyscrasia Treatment Versus Placebo and Plasma Cell Dyscrasia Treatment in Plasma Cell Dyscrasia Treatment-Naïve Patients with Mayo Stage IIIa AL Amyloidosis – A Study to Evaluate the Efficacy and Safety of AKCEA-TTR-LRx With Transthyretin Amyloidosis With Cardiomyopathy (ATTR Amyloidosis With Cardiomyopathy)

What is the drug in question?
CAEL-101 is a monoclonal antibody that attaches itself to part of the AL amyloid fibril in your tissues, and makes it easier for your own immune system to clear the amyloid deposits.

Who is eligible for the trial?
Patients with symptomatic newly diagnosed AL cardiac amyloidosis are eligible for these trials.
Patients who have already had treatment for their AL amyloidosis, or those without significant heart involvement are not eligible/
Does every patient receive the actual trial drug?
These are international Phase 3 prospective randomised placebo-controlled double-blinded studies.
All patients will receive the normal treatment for new diagnosed AL amyloidosis, that being bortezomib (Velcade), cyclophosphamide and dexamethasone.
In addition, patients will be randomized 2:1 to also receive either the CAEL-101 infusion delivered through an IV line into your vein (a “drip”) or the placebo (“dummy” drug) infusion. That means you have a 2 out of 3 chance of receiving the active drug. Neither you nor your doctor will know whether you are on the active drug or the placebo.

How is the drug administered?
CAEL-101 is administered as a intravenous (“a drip into a vein”) infusion. Patients will receive their injection weekly for four weeks then fortnightly.

How long does the trial go for?
At least 50 weeks (almost a year).

Anything else I need to know?
As part of the assessment for the trial, you will need to undergo several 6 minute walking tests, echocardiography (heart ultrasounds), and complete quality of life questionairres.

Key inclusion criteria:
Systemic AL (not ATTR) amyloidosis, involving the heart, as proven by

  1. Biopsy proof for amyloid deposits (such as bone marrow, kidney or heart biopsy)
  2. Cardiac MRI and/or echocardiography demonstrating signs of cardiac amyloidosis
  3. Elevated serum free light chains >40mg/L.
  4. NT-proBNP >650ng/L

Key exclusion criteria:

  1. Patients who have received previous therapy for AL Amyloidosis
  2. Patients whose systolic blood pressure if <90mmHg
  3. Patients on dialysis, or taking high doses of prednisolone or doxycycline.

AFFIRM-AL (NEOD001-301): A Phase 3 Randomized, MultI-Centre Double-Blind, Placebo-Controlled, Efficacy and Safety Study of Birtamimab Plus Standard of Care vs Placebo Plus Standard of Care in Newly Diagnosed Mayo Stage IV Subjects with Light Chain AL Amyloidosis

What is the drug in question?
Birtamimab – this is a monoclonal antibody that attaches to the amyloid deposits and hopefully this promotes your own immune system to clear the amyloid deposits in your body. This is combined with the typical standard treatment, usually “VCD” chemotherapy.

Who is eligible for the trial?
Newly diagnosed patients with systemic AL amyloidosis with advanced disease in the heart.

Does every patient receive the actual trial drug?
Two out of every three patients will receive birtamimab and one out of three will receive a placebo (“dummy”) drug. Neither you nor your treating team will know which drug you are on.

How is the drug administered?
Birtamimab is given through an IV (drip into the vein) every 28 days

How long does the trial go for?
Once 135 patients have received at least 9 months of treatment, the data will be analysed, and a decision of whether to stop the trial or continue will be made then.

Anything else I need to know?
This trial has been previously performed in patients with newly diagnosed AL amyloidosis but only those with advanced heart disease appeared to possibly benefit. This current trial called “AFFIRM” is looking to see whether a benefit can be proven in more advanced heart disease when a larger number of patients are analysed.rres.

Relapsed/refractory:

Phase I Study of AT-02 in Healthy Volunteers and Subjects With Systemic Amyloidosis (AT02-001)

What is the drug in question?

“AT-02” is a full-length, humanised, recombinant immunoglobulin 1(IgG1)-like glycoprotein monoclonal antibody (mAb) fusion protein that has been developed to treat any form of systemic amyloidosis.

Monoclonal antibodies has been used extensively in many disease, including in AL amyloidosis. Drugs such as Daratumumab, rituximab, isatuximab and elotuzumab are all mAbs.

AT-02 has binding potency to ATTR and AL amyloid, and is thought to opsonise amyloid extracts promoting macrophage-mediated phagocytosis of the amyloid.  In other words, the drug “latches onto” amyloid deposits and sends a signal to the immune system to clear deposits from the organ.

Cardiac, renal and hepatic amyloid deposits were shown to regress in mouse studies of this drug.

The most effective and highest well-tolerated dose of AT-02 in amyloidosis patients has not been determined. This Phase I trial is looking at different doses of AT-02  to see how well this drug is tolerated at a single once-off dose, and to determine the “MTD” or maximum tolerated dose.

Who is eligible for the trial?

Patients with any type of systemic amyloidosis with organ involvement with amyloid but reasonable kidney function (eGFR >30ml/min) are eligible. Patients with only localised disease or those with poor rkidney function are not eligible.

Does every patient receive the actual trial drug?

All patients will receive active drug. There is no placebo-arm to this study.

How is the drug administered?

AT-02 is an IV infusion through a drip. All patients receive paracetamol, and antihistamine and a steroid to reduce the chance of an infusion-related reaction, such as muscle aches, fevers and shakes, which are often seen during the first infusion of any mAb.

How long does the trial go for?

It is estimated that 14 patients will participate in this study to determine the MTD. Patients will be followed up for 3 months by the trials team after the dose is administered, in addition to their regular reviews with their treating amyloid specialist.

However, there will be another study following this one, where patients will receive 4 x weekly IV infusions of AT-02. There will be scans of the heart and liver before and after the 4 infusions, to see if there is any evidence of amyloid regression.

Key inclusion criteria:

  1. A biopsy-confirmed diagnosis of amyloidosis based on one of the following: histopathology (positive Congo red-stained tissue confirmed by immunohistochemistry demonstrating light chain deposition without the presence of transthyretin), the presence of characteristic appearance on electron microscopy, or mass spectrometry typing of amyloid.
  2. History of organ involvement that included at least one of the following:
    • Renal: albuminuria or non-Bence Jones proteinuria > 0.5 g/day by 24-hour urine collection.
    • Cardiac: mean left ventricular wall thickness on echocardiogram more than 12 mm in the absence of a history of hypertension or valvular heart disease or unexplained low voltage (< 0.5 mV) on ECG; or NT-ProBNP > 332 ng/L (or BNP > 81-ng/L) in the absence of renal failure.
    • Hepatic: hepatomegaly on PE or ultrasound or alkaline phosphatase > 1.5 × the upper limit of normal (ULN).
    • Gastrointestinal: direct biopsy verification of amyloid deposition and gastrointestinal symptoms, such as gastrointestinal bleeding or diarrhea.
    • Neurologic: symmetrical lower extremity sensorimotor peripheral neuropathy or autonomic neuropathy, including gastric motility disorder, pseudo-obstruction, or voiding dysfunction unrelated to direct organ infiltration.
  3. ECOG score of ≤ 2.
  4. Adequate organ function as follows:
    • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 × ULN.
    • Alkaline phosphatase ≤ 5 × ULN.
    • Total bilirubin ≤ 1.5 × ULN except for subjects with Gilbert syndrome.
    • Serum albumin ≥ 2 g/dL (20 g/L).
    • eGFR ≥ 30 mL/min/1.73 m2

A Phase II trial to evaluate the efficacy of Isatuximab plus Pomalidomide and Dexamethasone in patients with AL amyloidosis not in VGPR or better after any previous therapy

What is the drug in question?
Isatuximab is a monoclonal antibody that attacks the amyloid-forming plasma cells and helps your own immune system to kill these abnormal cells. It is very similar to daratumumab which is a highly effective treatment in AL amyloidosis.
Pomalidomide is an immunomodulatory drug which has been used for many years in myeloma, and has been shown to be effective and well tolerated in AL amyloidosis.
Dexamethasone is a steroid which also acts to suppress the production of the amyloid-forming plasma cells, and is usually combined with other treatments to improve their efficiency in destroying the amyloid-causing plasma cells and light chains.

Who is eligible for the trial?
Any patient with AL amyloidosis who have received at least one line of treatment with cyclophosphamide or melphalan and/or Velcade or ixazomib, and dexamethasone and not be in VGPR or better at the time of inclusion.

A “VGPR” stands for “Very Good Partial Response”, which is when the amyloid-making light chain is not more than 40mg/L greater than the other light chain. For instance, a patient with a lambda light chain of 55mg/L and a kappa light chain of 20mg/L would usually be consider in VGPR if the lambda light chains were the amyloid-causing light chains.

Does every patient receive the actual trial drug?
Yes, all patients receive isatuximab, pomalidomide and dexamethasone treatment.

How is the drug administered?
Pomalidomide and dexamethasone are oral tablets, while isatuximab is an intravenous (IV; through a “drip” in your arm) infusion.

Isatuximab will be given weekly for the first month then fortnightly for the remainder of the 12 month trial.

Pomalidomide is a tablet taken every day for 3 weeks then you have a week off. This is repeated every 4 weeks.
Dexamethasone is tablet taken once per week.

How long does the trial go for?
The trial will run for up to 12 months, but for those patients who achieve a complete 100% response to the treatment, the trial finishes after 9 months. However, patients will be followed up after the trial finishes every few months for up to 4 years.

Anything else I need to know?

Key inclusion criteria:

  1. Age: ≥18
  2. Histologic diagnosis of AL amyloidosis

A Single-Arm, Open-Label, Phase 1/2 Study of ZN-d5 for the Treatment of Relapsed or Refractory Light Chain (AL) Amyloidosis

What is the drug in question?
This is a novel BCL-2 inhibitor, similar to venetoclax.

Inhibiting BCL-2 can lead to death in tumour cells dependent on BCL-2 activity, including multiple myeloma cells. Venetoclax has activity in relapsed and refractory AL amyloidosis.

This trial hopes to prove that ZN-d5 will be at least as effective as venetoclax in killing amyloid-forming plasma cells.

Who is eligible for the trial?
Patients with relapsed and refractory AL amyloidosis who have had disease relapse/progression or lack of response to 1 to 3 prior lines of therapy.

Does every patient receive the actual trial drug?
All patients will receive active drug. There is no placebo-arm to this study. ZN-d5 is not given with any other therapy.

How is the drug administered?
ZN-d5 is a oral tablet.

How long does the trial go for?
Up to 135 patients will be included in the trial. Subjects will remain on treatment until disease progression, adverse events, withdrawal of consent, death, or the end of the study.

Anything else I need to know?
This trial has been previously performed in patients with newly diagnosed AL amyloidosis but only those with advanced heart disease appeared to possibly benefit. This current trial called “AFFIRM” is looking to see whether a benefit can be proven in more advanced heart disease when a larger number of patients are analysed.

Key inclusion criteria:

A Phase Ib/II Open-Label Study of APG2575 in Combination with Novel Therapeutic Regimens in Subjects with Relapsed or Refractory Multiple Myeloma and Immunoglobulin Light Chain Amyloidosis

APG-2575 (varying doses) + pomalidomide and dexamethasone (Pd)

What is the drug in question?
Approximately 50% of patients with AL amyloidosis have a chromosomal (genetic) change involving part of chromosome 11 swapping with part of chromosome 14, referred to as “t(11;14)”. BCL-2 inhibitors target this mutation and can cause cell death of the plasma cells that make the amyloid. APG-2575 is a novel BCL-2 inhibitor.

In this study, APG-2575 is combined with pomalidomide, an immunomodulatory drug which has been used extensively in myeloma, and appears to be effective and well tolerated in AL amyloidosis too. Dexamethasone, a steroid, is also combined with APG-2575 and pomalidomide, to hopefully enhance the effect of the drug.
During the study, patients will be assigned different doses of APG-2575 to determine the highest dose that is the best tolerated.

Who is eligible for the trial?
Any patient with relapsed AL amyloidosis with organ involvement (eg. heart and/or kidneys), or a patient who has not achieved an excellent response to their first 3 cycles of front-line chemotherapy.

Does every patient receive the actual trial drug?
Yes, all patients receive APG-2575, pomalidomide and dexamethasone

How is the drug administered?
This is an all oral, tablet treatment

Transthyretin Amyloidosis (ATTR) trials

The “Cardio TTRansform” trial for ATTR Amyloidosis is now open in Australia!

Please click on the links below for more details.

If the Cardio TTRansform study isn’t right for you or not available in your area, there are still treatments for ATTR readily available off-trial that your doctor can discuss with you. These include:

  • Diflunisal (similar to tafamidis) – available at all AAN services
  • Doxycycline and/or
  • EGCG (green tea extract).

Phase I Study of AT-02 in Healthy Volunteers and Subjects With Systemic Amyloidosis (AT02-001)

What is the drug in question?

“AT-02” is a full-length, humanised, recombinant immunoglobulin 1(IgG1)-like glycoprotein monoclonal antibody (mAb) fusion protein that has been developed to treat any form of systemic amyloidosis.

Monoclonal antibodies has been used extensively in many disease, including in AL amyloidosis. Drugs such as Daratumumab, rituximab, isatuximab and elotuzumab are all mAbs.

AT-02 has binding potency to ATTR and AL amyloid, and is thought to opsonise amyloid extracts promoting macrophage-mediated phagocytosis of the amyloid.  In other words, the drug “latches onto” amyloid deposits and sends a signal to the immune system to clear deposits from the organ.

Cardiac, renal and hepatic amyloid deposits were shown to regress in mouse studies of this drug.

The most effective and highest well-tolerated dose of AT-02 in amyloidosis patients has not been determined. This Phase I trial is looking at different doses of AT-02  to see how well this drug is tolerated at a single once-off dose, and to determine the “MTD” or maximum tolerated dose.

Who is eligible for the trial?

Patients with any type of systemic amyloidosis with organ involvement with amyloid but reasonable kidney function (eGFR >30ml/min) are eligible. Patients with only localised disease or those with poor rkidney function are not eligible.

Does every patient receive the actual trial drug?

All patients will receive active drug. There is no placebo-arm to this study.

How is the drug administered?

AT-02 is an IV infusion through a drip. All patients receive paracetamol, and antihistamine and a steroid to reduce the chance of an infusion-related reaction, such as muscle aches, fevers and shakes, which are often seen during the first infusion of any mAb.

How long does the trial go for?

It is estimated that 14 patients will participate in this study to determine the MTD. Patients will be followed up for 3 months by the trials team after the dose is administered, in addition to their regular reviews with their treating amyloid specialist.

However, there will be another study following this one, where patients will receive 4 x weekly IV infusions of AT-02. There will be scans of the heart and liver before and after the 4 infusions, to see if there is any evidence of amyloid regression.

Key inclusion criteria:

  1. A biopsy-confirmed diagnosis of amyloidosis based on one of the following: histopathology (positive Congo red-stained tissue confirmed by immunohistochemistry demonstrating light chain deposition without the presence of transthyretin), the presence of characteristic appearance on electron microscopy, or mass spectrometry typing of amyloid.
  2. History of organ involvement that included at least one of the following:
    • Renal: albuminuria or non-Bence Jones proteinuria > 0.5 g/day by 24-hour urine collection.
    • Cardiac: mean left ventricular wall thickness on echocardiogram more than 12 mm in the absence of a history of hypertension or valvular heart disease or unexplained low voltage (< 0.5 mV) on ECG; or NT-ProBNP > 332 ng/L (or BNP > 81-ng/L) in the absence of renal failure.
    • Hepatic: hepatomegaly on PE or ultrasound or alkaline phosphatase > 1.5 × the upper limit of normal (ULN).
    • Gastrointestinal: direct biopsy verification of amyloid deposition and gastrointestinal symptoms, such as gastrointestinal bleeding or diarrhea.
    • Neurologic: symmetrical lower extremity sensorimotor peripheral neuropathy or autonomic neuropathy, including gastric motility disorder, pseudo-obstruction, or voiding dysfunction unrelated to direct organ infiltration.
  3. ECOG score of ≤ 2.
  4. Adequate organ function as follows:
    • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 × ULN.
    • Alkaline phosphatase ≤ 5 × ULN.
    • Total bilirubin ≤ 1.5 × ULN except for subjects with Gilbert syndrome.
    • Serum albumin ≥ 2 g/dL (20 g/L).
    • eGFR ≥ 30 mL/min/1.73 m2

PLEASE NOTE THAT THE CARDIO-TTRANSFORM STUDY CLOSED TO RECRUITMENT ON 23RD MAY, 2023

A Study to Evaluate the Efficacy and Safety of AKCEA-TTR-LRx With Transthyretin Amyloidosis With Cardiomyopathy (ATTR Amyloidosis With Cardiomyopathy)

What is the drug in question?

AKCEA-TTR-LRx is a gene-silencing therapy, designed to reduce the production of TTR by the liver, and thus slow or stop the formation and progression of TTR amyloidosis.

Who is eligible for the trial?

Patients with symptomatic ATTR cardiac amyloidosis are eligible for this trial.

Both ATTRwt (wild-type) and ATTRv (hereditary) disease groups are included.

Does every patient receive the actual trial drug?

This is an international Phase 3 prospective randomised placebo-controlled double-blinded study.

Patients will be randomized 1:1 (50;50 chance) to receive either the AKCEA-TTR-LRx injection or the placebo (“dummy” drug) injection. Neither you nor your doctor will know whether you are on the active drug or the placebo.

How is the drug administered?

AKCEA-TTR-LRx is administered as a subcutaneous (“under the skin”) injection. Patients will receive their injection every four weeks

How long does the trial go for?

The TTRansform trial lasts 120 weeks (27 months).

Anything else I need to know?

Patients can also take EGCG and/or tafamidis during the study, but not diflunisal or doxycycline.

N.B. Neither EGCG nor Tafamidis will be supplied by the drug company, and tafamidis is currently not available on the PBS.

Key inclusion criteria:

1. “Symptomatic” heart failure defined as requiring hospitalisation or current/prior diuretic management.

2. NT-proBNP 600-6000 ng/L.

Key exclusion criteria:

1. Monoclonal gammopathy of undetermined significance (MGUS) unless fat, bone marrow, or heart biopsy confirms the absence of AL amyloid by mass spectrometry or immunoelectron microscopy.

2. eGFR <30mL/min/1.73 m2

3. Prior liver or heart transplant.
