BCD With or Without Doxycycline in Mayo Stage II-III Light Chain Amyloidosis Patients

Survival of intermediate and high-risk primary light chain amyloidosis (pAL) remains poor due to high mortality within 3-6 months of diagnosis. Rapidly effective regimens such as bortezomib, cyclophosphamide and dexamethasone (BCD) still failed to overcome the poor prognosis in very advanced pAL amyloidosis patients. Recently, doxycycline was demonstrated to induce disruption of fibril formation and reduce the number of intact fibrils in transgenic mouse model of pAL amyloidosis. Furthermore, case-control study suggested that adjuvant oral doxycycline could improve response and survival in cardiac pAL amyloidosis, which necessities further confirmation through a randomized trial. Therefore, we designed a multi-center randomized open-label controlled study to investigate the efficacy and safety of co-administration of oral doxycycline with BCD regimen in treatment-naïve patients with Mayo stage II-III pAL amyloidosis. The primary outcome progression-free survival, and secondary endpoints including overall survival, hematologic response, organ response and toxicity of doxycycline will be evaluated.

Treatment and study plan

Doxycycline

Drug

Oral doxycycline 100mg twice daily

bortezomib

Drug

1.3mg/m2 of bortezomib on days 1, 8, 15 and 22 of a 35-day cycle

Cyclophosphamide

Drug

300mg/m2 cyclophosphamide on days 1, 8, 15 and 22 of a 35-day cycle

Dexamethasone

Drug

40mg of dexamethasone on days 1, 8, 15 and 22 of a 35-day cycle

Primary outcomes

  1. Progression-free survival

    Time frame: 2 years

    The patients are assessed after each cycle of chemotherapy following treatment initiation until progression, relapse, death or study closure at 24-month follow-up.

Secondary outcomes

  1. Overall survival

    Time frame: 2 years

    The patients are assessed after each cycle of chemotherapy following treatment initiation until progression, relapse, death or study closure at 24-month follow-up. If the primary endpoint has reached, patients will also be followed up every 3 months thereafter until death or study closure.

  2. Hematologic response

    Time frame: 2 years

    The patients are assessed after each cycle of chemotherapy following treatment initiation until progression, relapse, death or study closure at 24-month follow-up. If the primary endpoint has reached, patients will also be followed up every 3 months thereafter until death or study closure.

  3. Organ response

    Time frame: 2 years

    The patients are assessed after each cycle of chemotherapy following treatment initiation until progression, relapse, death or study closure at 24-month follow-up. If the primary endpoint has reached, patients will also be followed up every 3 months thereafter until death or study closure.

  4. Adverse events

    Time frame: up to 2 years

    Adverse events are collected until 30 days after last dose of doxycycline.
