27The gastrointestinal adverse-effect profile resembles that of the incretin agonists, with nausea predominating and concentrated during escalation. Whether combining two agents that both delay gastric emptying compounds this is a question the combination trials address only indirectly.27The gastrointestinal adverse-effect profile resembles that of the incretin agonists, with nausea predominating and concentrated during escalation.

+30Amylin analogues are among the more demanding peptides to characterise, precisely because of the property they were engineered to remove. Residual aggregation propensity means that size-exclusion chromatography and, where available, orthogonal light-scattering methods carry more weight in a specification than they would for a non-aggregating peptide.{{r|usp1503,ich_q6b}}

+32The distinction between reversible self-association and irreversible aggregation matters here as it does for acylated peptides: a size-based method run under dissociating conditions can report a clean profile on material that shows high-molecular-weight species under native conditions. See [[Peptide aggregation]].
