The cancer biology concerns with c-Met activation are most relevant to chronic use
This is a fact-specific question that depends on the state, the pharmacy, the clinical context, and the prescribers rationale
Key structural features include N14E and V17R substitutions (helix stabilisation), 25P/28P/29P proline substitutions (suppression of beta-sheet propensity and amyloid fibril formation, the primary instability mode of native human amylin), a C-terminal proline-to-tyrosine substitution (P37Y) for calcitonin-receptor activity, and N-terminal C20 fatty-diacid acylation via a gamma-Glu linker
