AL Amyloidosis Clinical Trial
Doxycycline to Upgrade Organ Response in Light Chain (AL) Amyloidosis Trial
Summary
In this study the investigators want to find out more about the addition of the antibiotic, doxycycline, to standard anti-amyloid therapy in people with amyloidosis. The investigators want to find out whether doxycycline improves the response to standard anti-amyloid therapy and whether it causes any problems (side effects).
Full Description
Organ response to anti-plasma cell therapy in AL amyloidosis tends to lags behind hematologic response as chemotherapy may not clear pre-formed organ amyloid. Doxycycline has been shown to have inhibitory effects on amyloid fibril formation as well as de-fibrillogenic effects and shown to be beneficial in in vitro, murine models and other preclinical studies. The investigators will prospectively evaluate the safety and efficacy of doxycycline in AL amyloidosis patients when used in conjunction with anti-plasma cell chemotherapy.
Eligibility Criteria
Inclusion Criteria:
Patients with biopsy proven AL amyloidosis.
Patients ≥ 18 years of age are eligible.

A negative pregnancy test will be required for all women of child bearing potential. Breast feeding is not permitted.
Patients who have previously been taking doxycycline will be eligible as long as there is no contraindication to stay on doxycycline 100 mg twice daily (BID) for 1 year in the opinion of the treating physician.
Creatinine clearance of >25 ml/min.
Exclusion Criteria:
Patients with severe malabsorption syndrome precluding absorption of oral agents will be excluded.
Known intolerance or allergic reactions with doxycycline.
Previous chemotherapy for AL amyloidosis.
