Drug delivery articles, resident articles, and retrieval systems e.g., for gram-level dosing, are generally provided. In some embodiments, the residence articles are configured for transesophageal administration, transesophageal retrieval, and/or gastric retention to/in a subject. In certain embodiments, the residence article includes dimensions configured for transesophageal administration with a gastric resident system. In some cases, the residence article may be configured to control drug release e.g., with zero-order drug kinetics with no potential for burst release for weeks to months. In some embodiments, the residence articles described herein comprise biocompatible materials and/or are safe for gastric retention. In certain embodiments, the residence article includes dimensions configured for transesophageal retrieval. In some cases, the residence articles described herein may comprise relatively large doses of drug (e.g., greater than or equal to 1 gram).
