DapagliFLOzin in Renal AL Amyloidosis (FLORAL)

Description

The goal of this clinical trial is to learn if an oral drug called dapagliflozin is safe and can reduce high protein levels in the urine of patients with renal amyloid light-chain (AL) amyloidosis using a decentralized study design. Participants will be: * screened for the trial via an online platform * contacted by study personal to obtain electronic consent * enrolled in the trial if eligible and consented * contacted by study personal for further instructions and directions * sent dapagliflozin oral medication (supplied by the site pharmacy) * followed up regularly with the study team via telemedicine or other online avenues * monitored using lab work, inquiries about side effects and assessment of protocol adherence at 1 month, 3 months and 6 months * continue treatment for 6 months1. Participants are recruited by one of the following methods: 1. Self-referral through the website 2. Receiving recruitment materials from their provider. 2. Participant visits the prescreening
