Small molecule calpain modulator compositions and pharmaceutical compositions can be prepared and used as therapeutic agents. Exemplary compositions include non-macrocyclic a-keto amide derivatives. The therarapeutic agents can be used for treating fibrotic disease or a resulting secondary disease state or condition. The small molecules can competitively bind with calpastatin and/or inhibit calpain through contact with CAPN1, CAPN2, and/or CAPN9 enzymes.
