Detailed Description
Amyloidosis is a disorder of protein folding in which normally soluble proteins are deposited as abnormal, insoluble fibrils that progressively disrupt tissue structure and impair function. The treatment of systemic AL amyloidosis has evolved to a risk adapted approach based on the end organ damage, particularly cardiac involvement, and the functional status of the patient. Intensive therapies like high dose melphalan followed by an autologous stem cell transplant are considered for patients with limited organ involvement, younger age and excellent functional status.
The majority of patients with AL amyloidosis, however, will not be candidates for ASCT and are generally treated with combination chemotherapy. This therapy may include bortezomib, a proteasome inhibitor which is particularly effective in AL amyloidosis but which may have a severe side-effect profile.
Carfilzomib is specific for the chymotrypsin-like active site of the 20S proteasome, is structurally and mechanistically distinct from bortezomib, and has demonstrated less reactivity against non-proteasomal proteases when compared to bortezomib. It also appears to be better tolerated. However, information regarding the use of carfilzomib in the treatment of AL amyloidosis is limited.
In the dose escalation phase of this study, a minimum of 6 (3 at dose level 0 and 3 at dose level -1)and a maximum of 18 (6 at dose level 0, 1, and 2) patients will recruited in a 3+3 design with cohorts of between 3 and 6 patients, in order to determine maximum tolerated dose and recommended dose.
At the recommended dose level identified, a further 20 (minimum) patients will be recruited to further assess safety and toxicities at the RD.

The compliant profile of participants to KTD will be assessed by determining the number of missed doses from recorded data.
Participants will be regarded as compliant if participants have missed no more than 14 days of thalidomide, 2 days of dexamethasone, and 1 dose of carfilzomib per cycle.
Compliance will be reported in terms of the number of participants who were compliant.
